Individuals with seasonal affective disorder (SAD) may have a decreased retinal sensitivity in the non-image forming light-input pathway. We examined the post illumination pupil response (PIPR) among individuals with SAD and healthy controls to identify possible differences in the melanopsin signaling pathway. We also investigated whether melanopsin gene(More)
In two recent reports, melanopsin gene variations were associated with seasonal affective disorder (SAD), and in changes in the timing of sleep and activity in healthy individuals. New studies have deepened our understanding of the retinohypothalamic tract, which translates environmental light received by the retina into neural signals sent to a set of(More)
Objectives: To study the role of apomorphine in the development of Parkinson's disease de novo Impulse compulsive behaviours (ICBs) or recurrence of pre-existing ICBs in a retrospective audit. Background: Impulsive compulsive behaviours (ICBs) such as pathological gambling, compulsive sexual behaviour, compulsive eating and shopping and the overuse of(More)
Eating pathology in Seasonal Affective Disorder (SAD) may be more severe than hyperphagia during winter. Although research has documented elevated rates of subclinical binge eating in women with SAD, the prevalence and correlates of binge eating disorder (BED) in SAD remain largely uncharacterized. We examined the prevalence and correlates of binge eating,(More)
