Seasonal Pattern in Mood Disorders
Captions available
The idea
A seasonal pattern is a specifier applied when depressive episodes recur at a characteristic time of year.
In practice
Episodes begin each autumn and remit each spring across several consecutive years.
Where people slip
Under DSM-5 and DSM-5-TR this is a specifier on a mood disorder, not a separate diagnosis.
