The current study examined whether depressed outpatients with comorbid SAD respond differently to a cognitive-behavioral group intervention and if so, how and why. Using growth curve modeling, we found evidence that depressed clients with comorbid SAD had rapid improvement in depressive symptoms over the course of treatment and generally did not differ from those without comorbidity in developi...

BACKGROUND Retinal sensitivity may play a role in the pathogenesis of seasonal affective disorder (SAD) and response to light therapy. METHODS Using a dark adaptation procedure, SAD patients and normal control subjects were tested in the winter and summer, with patients retested after light treatment. The eyes were preadapted to bright light followed by 30 min in darkness, during which subjec...

OBJECTIVE The purpose of this study was to assess the evidence base for the efficacy of light therapy in treating mood disorders. METHOD The authors systematically searched PubMed (January 1975 to July 2003) to identify randomized, controlled trials of light therapy for mood disorders that fulfilled predefined criteria. These articles were abstracted, and data were synthesized by disease and ...

The etiology and pathophysiology of seasonal affective disorder (SAD) has been linked to the seasons and to light since its first conceptualization. Aspects of SAD that make it particularly amenable to biological investigation include the predictable recurrent episodes, the rapid response to a nonpharmacologic treatment, the specific neurovegetative features, and the availability of rich animal...

OBJECTIVE In adults with attention-deficit/ hyperactivity disorder (ADHD), a delayed sleep/ activity rhythm and/or seasonal mood symptoms may contribute significantly to core pathology and disability. This study examined whether a chronobiologically based treatment, i.e., morning bright light therapy (LT), might have utility as an adjunctive treatment for adult ADHD in the fall/ winter period. ...
