10 SAD Symptoms

Symptom #7: Anhedonia
Anhedonia is a term describing reduced ability or motivation to experience pleasure. This can be seen when individuals no longer feel encouraged or feel pleasure from activities that they once enjoyed. It is an important component often seen in depressive disorders (such as major depression disorder and seasonal affective disorder), personality disorders, substance-related issues, and psychotic disorders.
Anhedonia is thought to be due to the affected prefrontal cortex especially the striatum, amygdala, orbitofrontal cortex, hypothalamus, anterior cingulate cortex, and ventral tegmental area.
