Abstract
BACKGROUND:
The objective of this study was to estimate the prevalence of Seasonal Affective Disorder (SAD) in adults with lifetime Attention-Deficit/Hyperactivity Disorder (ADHD).
METHOD:
Patients eligible for this study had lifetime impairing symptoms of ADHD and a current and/or past co-morbid mood disorder according to their medical record. The Seasonal Pattern Assessment Questionnaire (SPAQ) was administered by a telephone interview to assess seasonality.
RESULTS:
The overall rate of SAD in this clinical population of adults with ADHD was estimated at 27%. Females were more at risk to develop SAD than men.
LIMITATIONS:
The SPAQ is a screening, not a diagnostic instrument.
CONCLUSIONS:
SAD symptoms are frequently comorbid with ADHD in adults. These results have clinical relevance for the recognition and treatment of SAD with bright light therapy in adults with ADHD.
