Schizoid Personality Disorder (SPD) is a mental health condition characterized by a persistent pattern of detachment from social relationships, a limited range of emotional expression, and a lack of interest in sexual experiences. Individuals with SPD often prefer solitary activities and have a tendency to be indifferent to praise or criticism. This pattern of behavior must be present throughout adulthood and must cause significant distress or impairment in daily functioning in order to be diagnosed with SPD.

Prevalence of SPD in the general population

The exact prevalence of Schizoid Personality Disorder (SPD) in the general population is not well established. Studies suggest that SPD occurs in around 1-2% of the general population, although the actual number may be higher as SPD is often underdiagnosed. SPD is more common in men than in women. It is not to be confused with Schizophrenia which is a different type of disorder altogether.

Brief overview of the symptoms of SPD

Schizoid Personality Disorder (SPD) is characterized by a persistent pattern of detachment from social relationships, a limited range of emotional expression, and a lack of interest in sexual experiences. Some of the main symptoms of SPD include:

Detachment from social relationships: Individuals with SPD often have a limited number of close relationships, if any at all. They may avoid social activities and have a tendency to be solitary.
Limited range of emotional expression: Individuals with SPD may appear emotionally detached or indifferent to others. They may have difficulty expressing emotions or understanding the emotions of others.
Lack of desire for sexual experiences: Individuals with SPD may have little or no interest in sexual experiences.
Indifference to praise or criticism: Individuals with SPD may not be affected by praise or criticism and may not be motivated by rewards or recognition.
Preference for solitary activities: Individuals with SPD may prefer to spend time alone, rather than engaging in social activities.

It is important to note that these symptoms must be present throughout adulthood and must cause significant distress or impairment in daily functioning in order to be diagnosed with SPD.

Causes of SPD

Genetic factors

Research suggests that genetic factors may play a role in the development of Schizoid Personality Disorder (SPD). Studies of twins and families have shown that there is a higher concordance rate for SPD among identical twins than fraternal twins, indicating a potential genetic component. However, the specific genes that may be associated with SPD are not well understood.

It’s also worth noting that SPD is considered a complex trait disorder which means that multiple genes may influence the development of SPD in combination with environmental factors.

Additionally, research has found that there may be an association between SPD and the genetic variation in certain neurotransmitters such as dopamine and serotonin, which play a role in regulating mood, emotions, and social behavior.

More research is needed to better understand the specific genetic factors associated with SPD, but it is likely that a combination of genetic and environmental factors contribute to the development of the disorder.

Environmental factors

In addition to genetic factors, environmental factors may also play a role in the development of Schizoid Personality Disorder (SPD). Some environmental factors that have been suggested as contributing to the development of SPD include:

Childhood experiences: Trauma, abuse, or neglect in childhood may contribute to the development of SPD. Negative childhood experiences may cause a person to develop a distrust of others and a tendency to withdraw from social interactions.
Social isolation: Growing up in a socially isolated environment, such as living in a remote area or being the only child of elderly parents, may contribute to the development of SPD.
Parenting style: Parents who are emotionally distant or neglectful may contribute to the development of SPD in their children.
Cultural and societal factors: Societal and cultural factors, such as a lack of emphasis on social connections and emotions, may also contribute to the development of SPD.

It is important to note that environmental factors alone do not cause SPD, it’s the interplay of both genetic and environmental factors that contribute to the development of the disorder.

Also, it is worth noting that while SPD is considered a personality disorder, it can also be diagnosed as a subtype of schizophrenia or as a schizoid disorder of childhood or adolescence. Therefore, environmental factors related to onset and development of schizophrenia may play a role in the development of SPD.

Brain chemistry and structure

Research suggests that brain chemistry and structure may play a role in the development of Schizoid Personality Disorder (SPD). Studies have found that individuals with SPD may have abnormalities in certain neurotransmitters, which are chemicals in the brain that transmit signals between nerve cells.

Some studies have found that individuals with SPD have lower levels of the neurotransmitters dopamine and serotonin, which play a role in regulating mood, emotions, and social behavior. These changes in neurotransmitters may contribute to the emotional detachment and lack of interest in social interactions that are characteristic of SPD.

Additionally, studies have shown that people with SPD have structural brain abnormalities like changes in gray matter volume and thickness in certain areas of the brain that are associated with social cognition, emotion regulation, and decision-making.

However, it’s important to note that more research is needed to understand the specific brain chemistry and structural changes associated with SPD, and it’s likely that the underlying neural mechanisms of SPD are complex and multifactorial.

It’s also worth noting that SPD is considered a personality disorder, it can also be diagnosed as a subtype of schizophrenia or as a schizoid disorder of childhood or adolescence. Therefore, brain chemistry and structural changes associated with schizophrenia may play a role in the development of SPD.

Symptoms of SPD

Detachment from social relationships

Detachment from social relationships is a core symptom of Schizoid Personality Disorder (SPD). Individuals with SPD often have a limited number of close relationships, if any at all. They may avoid social activities and have a tendency to be solitary. They may not seek out or enjoy social interactions and may prefer to spend time alone, rather than engaging in social activities. They may appear emotionally detached or indifferent to others and have difficulty expressing emotions or understanding the emotions of others.

This detachment from social relationships can be a result of several factors, such as:

Negative childhood experiences: Trauma, abuse, or neglect in childhood may cause a person to develop a distrust of others and a tendency to withdraw from social interactions.
Social isolation: Growing up in a socially isolated environment, such as living in a remote area or being the only child of elderly parents, may contribute to the development of SPD.
Parenting style: Parents who are emotionally distant or neglectful may contribute to the development of SPD in their children.
Cultural and societal factors: Societal and cultural factors, such as a lack of emphasis on social connections and emotions, may also contribute to the development of SPD.
Abnormalities in certain neurotransmitters: Research suggests that lower levels of the neurotransmitters dopamine and serotonin, which play a role in regulating mood, emotions, and social behavior, may contribute to the emotional detachment and lack of interest in social interactions that are characteristic of SPD.

It is important to note that while detachment from social relationships is a core symptom of SPD, it is not a symptom that is unique to SPD and can be found in other disorders as well.

Limited range of emotional expression

Limited range of emotional expression is a symptom of Schizoid Personality Disorder (SPD), which is characterized by emotional detachment and a lack of interest in social interactions. People with SPD may have difficulty expressing emotions or understanding the emotions of others. They may appear emotionally flat or indifferent, and may have trouble expressing feelings or experiencing pleasure. They may also have difficulty recognizing the emotions of others, which can make it difficult for them to form and maintain relationships.

This limited range of emotional expression can be a result of several factors, such as:

Negative childhood experiences: Trauma, abuse, or neglect in childhood may cause a person to develop a distrust of others and a tendency to withdraw from social interactions, which can affect their ability to express emotions.
Social isolation: Growing up in a socially isolated environment, such as living in a remote area or being the only child of elderly parents, may contribute to the development of SPD.
Parenting style: Parents who are emotionally distant or neglectful may contribute to the development of SPD in their children.
Cultural and societal factors: Societal and cultural factors, such as a lack of emphasis on social connections and emotions, may also contribute to the development of SPD.
Abnormalities in certain neurotransmitters: Research suggests that lower levels of the neurotransmitters dopamine and serotonin, which play a role in regulating mood, emotions, and social behavior, may contribute to the emotional detachment and lack of interest in social interactions that are characteristic of SPD.

It’s worth noting that while limited range of emotional expression is a symptom of SPD, it is not a symptom that is unique to SPD and can be found in other disorders as well.

A lack of desire for sexual experiences

A lack of desire for sexual experiences is a symptom of Schizoid Personality Disorder (SPD). Individuals with SPD often have a limited interest in sexual relationships or activities, and may have little or no sexual drive. They may find little pleasure in sexual experiences, and may be indifferent to sexual advances from others. This lack of interest in sexual experiences can be a result of several factors, such as:

Emotional detachment: People with SPD often have difficulty expressing emotions and may be emotionally detached, which can affect their ability to form and maintain sexual relationships.
Social isolation: Individuals with SPD tend to avoid social interactions and have a tendency to be solitary, which may lead to a lack of opportunities for sexual experiences.
Fear of intimacy: People with SPD may have a fear of intimacy and may avoid close relationships, including sexual relationships, to avoid feeling emotionally vulnerable.
Abnormalities in certain neurotransmitters: Research suggests that lower levels of the neurotransmitters dopamine and serotonin, which play a role in regulating mood, emotions, and social behavior, may contribute to the emotional detachment and lack of interest in social and sexual interactions that are characteristic of SPD.

It’s worth noting that a lack of desire for sexual experiences can be a symptom of other disorders as well, such as hypoactive sexual desire disorder.

Indifference to praise or criticism

Indifference to praise or criticism is a symptom of Schizoid Personality Disorder (SPD). Individuals with SPD often have a limited range of emotions and may appear emotionally detached or indifferent to others. They may not seek out or enjoy social interactions and may prefer to spend time alone. They may have difficulty expressing emotions or understanding the emotions of others. As a result, they may not respond to praise or criticism in the way that others would expect.

People with SPD may not feel the need for validation from others, or may not care about it. They may not be interested in the opinions of others and may not be motivated by rewards or recognition. They may also have difficulty receiving constructive criticism, as they may not see the point of changing their behavior.

This indifference to praise or criticism can be a result of several factors, such as:

Negative childhood experiences: Trauma, abuse, or neglect in childhood may cause a person to develop a distrust of others and a tendency to withdraw from social interactions, which can affect their ability to respond to praise or criticism.
Social isolation: Growing up in a socially isolated environment, such as living in a remote area or being the only child of elderly parents, may contribute to the development of SPD.
Parenting style: Parents who are emotionally distant or neglectful may contribute to the development of SPD in their children.
Cultural and societal factors: Societal and cultural factors, such as a lack of emphasis on social connections and emotions, may also contribute to the development of SPD.
Abnormalities in certain neurotransmitters: Research suggests that lower levels of the neurotransmitters dopamine and serotonin, which play a role in regulating mood, emotions, and social behavior, may contribute to the emotional detachment and lack of interest in social interactions that are characteristic of SPD.

It’s worth noting that indifference to praise or criticism is not unique to SPD and can be a symptom of other disorders as well.

Preference for solitary activities

Preference for solitary activities is a symptom of Schizoid Personality Disorder (SPD). Individuals with SPD often have a limited range of emotions and may appear emotionally detached or indifferent to others. They may not seek out or enjoy social interactions and may prefer to spend time alone. They may have difficulty expressing emotions or understanding the emotions of others. As a result, they may prefer to engage in solitary activities rather than social activities.

People with SPD may enjoy activities such as reading, writing, drawing, or listening to music alone. They may also spend a lot of time alone doing activities such as working on a hobby or collecting things. They may not feel the need for social interaction or may not enjoy it as much as others do. They may also have difficulty initiating or maintaining social relationships.

This preference for solitary activities can be a result of several factors, such as:

Negative childhood experiences: Trauma, abuse, or neglect in childhood may cause a person to develop a distrust of others and a tendency to withdraw from social interactions.
Social isolation: Growing up in a socially isolated environment, such as living in a remote area or being the only child of elderly parents, may contribute to the development of SPD.
Parenting style: Parents who are emotionally distant or neglectful may contribute to the development of SPD in their children.
Cultural and societal factors: Societal and cultural factors, such as a lack of emphasis on social connections and emotions, may also contribute to the development of SPD.
Abnormalities in certain neurotransmitters: Research suggests that lower levels of the neurotransmitters dopamine and serotonin, which play a role in regulating mood, emotions, and social behavior, may contribute to the emotional detachment and lack of interest in social interactions that are characteristic of SPD.

It’s worth noting that preference for solitary activities can be a symptom of other disorders as well, such as social anxiety disorder or avoidant personality disorder.

Diagnosis of SPD

Criteria for diagnosis according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5)

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) is a widely used guide for diagnosing mental health disorders. According to the DSM-5, the criteria for a diagnosis of Schizoid Personality Disorder (SPD) include:

A pervasive pattern of detachment from social relationships and a restricted range of emotional expression in interpersonal settings, as indicated by four (or more) of the following:

Neither desires nor enjoys close relationships, including being part of a family
Almost always chooses solitary activities
Has little, if any, interest in having sexual experiences with another person
Takes pleasure in few, if any, activities
Lacks close friends or confidants other than first-degree relatives
Appears indifferent to the praise or criticism of others
Shows emotional coldness, detachment, or flattened affectivity

Does not occur exclusively during the course of Schizophrenia, Schizophreniform Disorder, Delusional Disorder, or Psychotic Disorder Not Otherwise Specified, and is not due to the direct physiological effects of a general medical condition.
The disorder causes clinically significant distress or impairment in social, occupational, or other areas of functioning.

To make a diagnosis of SPD, a mental health professional will typically perform a clinical interview, often using a structured diagnostic interview, to gather information about the individual’s symptoms, medical history, and social and family background. They may also use self-report questionnaires and other tools to assess the person’s level of functioning and emotional well-being.

It’s worth noting that SPD is a personality disorder, which by definition means that the characteristics have been present for a long time and have been stable over time. Also, to be diagnosed with SPD, the person must not have symptoms that meet criteria for another personality disorder, such as Schizotypal personality disorder, Paranoid personality disorder, or Schizophrenia.

Differential diagnosis with other personality disorders

Differential diagnosis is the process of distinguishing one disorder from another, based on their symptoms and characteristics. It is important to differentiate Schizoid Personality Disorder (SPD) from other personality disorders, as the treatment and prognosis may vary.

SPD shares some similarities with other personality disorders, particularly Schizotypal Personality Disorder (STPD) and Avoidant Personality Disorder (AVPD). However, there are some key differences that help to distinguish these disorders:

Schizotypal Personality Disorder (STPD): STPD is characterized by odd or eccentric thinking, behavior, and communication, and a tendency to have abnormal perceptions or beliefs. People with STPD may also have a reduced capacity for close relationships and may be socially isolated, but they tend to have more anxiety and discomfort in social situations than people with SPD.
Avoidant Personality Disorder (AVPD): AVPD is characterized by a persistent fear of rejection, ridicule, or embarrassment, which leads to social withdrawal and isolation. People with AVPD tend to have a greater fear of social rejection, and are more likely to avoid social situations because of this fear, than people with SPD.

Other personality disorders that may be considered in the differential diagnosis of SPD are:

Paranoid Personality Disorder (PPD): PPD is characterized by a persistent mistrust of others, and the belief that others are exploiting, harming, or deceiving them. People with PPD tend to be more suspicious and guarded than people with SPD.
Schizophrenia: Schizophrenia is a severe mental disorder characterized by a breakdown of thought processes and a distorted perception of reality. People with schizophrenia may have symptoms such as hallucinations, delusions, and disorganized thinking, which are not present in SPD.
Depressive disorder: Depression is a mood disorder characterized by feelings of sadness, hopelessness, and a loss of interest in activities. People with depression may have a lack of interest in socializing, but they also have a lack of interest in anything, not only social activities.

It’s important to note that many people with SPD may not seek treatment, as they may not be troubled by their symptoms or may not be aware that they have a disorder. Therefore, it’s important for mental health professionals to be aware of the symptoms of SPD and to consider it as a possible diagnosis in individuals who present with social isolation, emotional detachment, and a lack of interest in social or sexual relationships.

Role of psychological evaluation and assessment

Psychological evaluation and assessment play a critical role in the diagnosis and treatment of Schizoid Personality Disorder (SPD). The process of psychological evaluation and assessment typically involves the following steps:

Clinical interview: A mental health professional will conduct a comprehensive interview with the individual to gather information about their symptoms, medical history, and social and family background. The professional will use a structured diagnostic interview, such as the Structured Clinical Interview for DSM-5 Personality Disorders (SCID-5-PD) or the Personality Assessment Schedule (PAS), which are designed to assess personality disorders.
Self-report questionnaires: The individual may also be asked to complete self-report questionnaires, such as the Millon Clinical Multiaxial Inventory-III (MCMI-III) or the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), which can provide additional information about their personality and emotional functioning.
Observation: The mental health professional may also observe the individual’s behavior, interactions, and communication in the assessment session, which can provide additional information about their emotional expression, social skills, and overall functioning.
Review of medical records: The mental health professional may also review the individual’s medical records, including any previous psychiatric evaluations or treatments.
Differential diagnosis: The mental health professional will use the information gathered through the evaluation and assessment to differentiate SPD from other personality disorders or mental health conditions that may present with similar symptoms.

The psychological evaluation and assessment process is important to ensure that an accurate diagnosis is made and that the individual receives appropriate treatment. A psychological evaluation can also help to identify any underlying mental health conditions that may be contributing to the individual’s symptoms, and can provide important information about their emotional functioning and social skills.

It’s also worth noting that psychological evaluations can also be used as an assessment tool to monitor progress, assess treatment outcomes and adjust interventions as needed to better meet the patient’s needs over time.

Treatment of SPD

Medications for SPD

Schizoid Personality Disorder (SPD) is considered a personality disorder, which means that the symptoms are primarily related to personality traits and patterns of behavior. As a result, medication is not typically the first line of treatment for SPD. However, medication may be considered as an adjunctive treatment in some cases, particularly if the individual also has co-occurring mental health conditions such as depression or anxiety.

Some of the medications that may be used to treat symptoms of SPD include:

Antidepressants: Selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) may be prescribed to treat symptoms of depression and anxiety that may be associated with SPD.
Antipsychotics: Atypical antipsychotics may be prescribed to treat symptoms of psychosis, such as delusions and hallucinations, that may be present in some individuals with SPD.
Mood stabilizers: Mood stabilizers such as lithium may be prescribed to treat symptoms of mood instability that may be associated with SPD.

It’s important to note that medication should always be used under the guidance of a qualified mental health professional, and that the treatment plan should be tailored to the individual’s specific needs and symptoms. Medication may not be the best treatment for everyone with SPD, and it’s important to explore other options such as therapy before considering medication.

It’s also worth noting that individuals with SPD may have difficulty engaging with treatment, so a thorough assessment and understanding of the patient’s personality and presenting symptoms is important before making any decisions about treatment options.

Therapy for SPD

Schizoid Personality Disorder (SPD) is considered a personality disorder, which means that the symptoms are primarily related to personality traits and patterns of behavior. As a result, therapy is typically the first line of treatment for SPD, and it can be an effective way to help individuals with SPD improve their social skills, emotional expression, and overall functioning.

Some of the therapy options that may be used to treat SPD include:

Psychodynamic therapy: This type of therapy explores the unconscious thoughts and feelings that may be contributing to the individual’s symptoms, and can help them gain insight into their behavior and relationships.
Cognitive-behavioral therapy (CBT): This type of therapy focuses on changing negative thoughts and behaviors that may be contributing to the individual’s symptoms. CBT can help individuals with SPD learn new ways of coping with stress and improve their social skills.
Interpersonal therapy (IPT): IPT focuses on improving the individual’s relationships and communication skills, which can be particularly beneficial for individuals with SPD who may have difficulty connecting with others.
Schema-focused therapy: This type of therapy focuses on identifying and changing maladaptive schemas, or patterns of thought, that may be contributing to the individual’s symptoms.
Group therapy: Group therapy can be particularly beneficial for individuals with SPD, as it can provide them with an opportunity to practice social skills and learn from others.

It’s important to note that therapy should always be used under the guidance of a qualified mental health professional, and that the treatment plan should be tailored to the individual’s specific needs and symptoms. It’s also worth noting that individuals with SPD may have difficulty engaging with treatment, so a thorough assessment and understanding of the patient’s personality and presenting symptoms is important before making any decisions about therapy options.

It’s also important to note that therapy can take time, and progress might be slower than for other disorders. This can be especially true for patients with SPD, who may have difficulty engaging with treatment. A therapist who is trained in personality disorders, and is familiar with the specific difficulties that these disorders pose, can be especially helpful in working with these patients.

Support groups for SPD

Support groups can be a helpful resource for individuals with Schizoid Personality Disorder (SPD) as they can provide a sense of community and a safe space for individuals to share their experiences and feelings. Here are a few ways that support groups can be helpful for people with SPD:

Understanding and validation: Support groups can provide individuals with SPD an opportunity to share their experiences with others who have similar struggles. This can help them feel understood and validated, which can be particularly important for individuals who may feel isolated or disconnected from others.
Coping strategies: Support groups can provide individuals with SPD an opportunity to learn from others about how to cope with their symptoms. They can share tips and strategies for managing stress, improving social skills, and building healthy relationships.
Connections: Support groups can provide individuals with SPD an opportunity to connect with others who understand what they are going through. This can help them feel less alone and isolated, which can be particularly beneficial for individuals who may struggle with social connections.
Education: Support groups can provide individuals with SPD an opportunity to learn more about the disorder, treatment options, and other resources that may be available to them.

It’s important to note that support groups should be used in conjunction with professional treatment and not as a standalone treatment. Support groups can also vary in terms of the format and structure, it’s important to find a group that is comfortable and fits the individual’s needs.

It’s also worth noting that individuals with SPD may have difficulty engaging with support groups, so it’s important to be patient and understanding, and to provide a supportive and non-judgmental environment.

Living with SPD

Coping strategies for individuals with SPD

Individuals with Schizoid Personality Disorder (SPD) may have difficulty connecting with others and expressing their emotions, which can make it challenging for them to cope with their symptoms. However, there are several coping strategies that may be helpful for individuals with SPD, including:

Building a support system: It can be difficult for individuals with SPD to connect with others, but building a support system of friends, family, or a therapist can provide a sense of connection and support.
Learning social skills: Individuals with SPD may struggle with social interactions and may benefit from learning and practicing social skills, such as conversation starters and active listening.
Mindfulness and relaxation techniques: Mindfulness and relaxation techniques, such as yoga, meditation, or deep breathing, can help individuals with SPD manage stress and improve emotional regulation.
Journaling: Journaling can be a helpful tool for individuals with SPD to process their thoughts and feelings and gain insight into their behavior.
Finding hobbies and interests: Finding hobbies and interests that they enjoy can provide individuals with SPD with a sense of purpose and fulfillment.
Seeking professional help: Seeking professional help from a therapist or counselor can be beneficial in addressing the underlying issues related to SPD and developing coping strategies.

It’s important to note that coping strategies will vary from person to person, and what works for one individual may not work for another. It’s important to be patient and persistent in finding coping strategies that work best for the individual, and to remember that progress may be slow, but it’s possible. It’s also important to keep in mind that the condition is chronic, and that there may be setbacks, but that does not mean that the treatment is not working.

Support for family and friends of individuals with SPD

Having a loved one with Schizoid Personality Disorder (SPD) can be challenging for family and friends. Here are a few ways that family and friends can support their loved one with SPD:

Educate yourself: Learn as much as you can about SPD and understand that it is a real condition that affects how your loved one interacts with others.
Be patient: People with SPD may have difficulty connecting with others and expressing their emotions, so it’s important to be patient and understanding.
Encourage professional help: Encourage your loved one to seek professional help and support them in finding a therapist or counselor who can help them manage their symptoms.
Communicate: Communicate clearly and honestly with your loved one and be open to hearing their thoughts and feelings.
Be consistent: People with SPD may have difficulty connecting with others, but be consistent in your efforts to build and maintain a relationship with them.
Encourage self-care: Encourage your loved one to take care of themselves, both physically and mentally, and to engage in activities that they enjoy.
Support their independence: While it can be hard for family and friends to not be able to help, it’s important to let the person with SPD make their own choices and learn from their own experiences.
Join a support group: Joining a support group for family and friends of individuals with SPD can be a helpful resource for you, as it can provide you with a sense of community and a safe space to share your experiences and feelings.

It’s important to remember that individuals with SPD may have difficulty connecting with others and may not be able to express their feelings or needs clearly, so it’s important to be patient, understanding, and supportive. It’s also important to take care of yourself, as caring for a loved one with SPD can be challenging, and to remember that you’re not alone in this.

Importance of early intervention and management of SPD

Early intervention and management of Schizoid Personality Disorder (SPD) is important for several reasons:

Improved outcomes: Early intervention and management can lead to improved outcomes for individuals with SPD. With proper treatment, individuals with SPD may be able to improve their ability to connect with others and manage their emotions more effectively.
Reduced symptoms: Early intervention and management can help reduce symptoms of SPD, such as detachment from social relationships and a limited range of emotional expression, which can improve overall quality of life.
Reduced risk of comorbid conditions: SPD is often comorbid with other conditions such as depression, anxiety, and substance abuse. Early intervention and management can reduce the risk of these comorbid conditions.
Improved functioning: Early intervention and management can improve an individual’s ability to function in their daily life, such as in their relationships and career.
Cost-effective: Early intervention and management can be more cost-effective in the long run, as untreated SPD can lead to more severe symptoms, which may require more extensive treatment in the future.

It’s important to note that not everyone who meets the criteria for SPD will require treatment. For some individuals, the condition may be relatively mild and may not cause significant problems in their daily lives. However, for those who do experience significant distress or impairment as a result of SPD, early intervention and management can be beneficial in improving their overall quality of life.
