Seasonal affective disorder is a type of depression associated with changes in the seasons – SAD begins and ends at about the same time each year. If you’re like most people with SAD, your symptoms start in the fall and continue in the winter months, undermining your energy and making you feel moody. Less frequently, SAD causes depression in the spring or early summer.

SAD Treatment may include light therapy, psychotherapy, and medications.

Do not dismiss that once a year, feeling like a case of the “winter blues” or a seasonal funk that you have to endure on your own. Instead, take measures to keep your mood and motivation steady throughout the year.

  • Melatonin levels – Changing seasons can disrupt the balance of the body levels of melatonin, which plays a role in sleep patterns and mood.

DSM-5 criteria for the diagnosis of depression with seasonality includes such experience, at least for the last two years:

  • Depression that starts during a particular season every year
  • Depression that ends during a specific season every year
  • No episodes of depression during the season in which you are experiencing everyday mood
  • Many more seasons depressed than nondepressed seasons for the duration of your illness services
