Light-Emitting Diode (LED) Light for Seasonal Affective Disorder (SAD) Treatment

BACKGROUND AND SIGNIFICANCE Discovery in the late 1970s that bright light affects neuroendocrine rhythms such as melatonin secretion, and can reset the circadian pacemaker in humans, paved the way for the discovery that seasonally recurrent fall/winter depressions--christened Seasonal Affective Disorder (SAD)--can be treated with bright light exposure (Lewy et al., ...

Phase N/A

Investigation of Seasonal Variations of Brain Structure and Connectivity in SAD

Seasonal Affective Disorder (SAD) is a subtype of Major Depressive Disorder, characterized by a recurrent temporal relationship between the season of year, the onset and the remission of a major depressive episode. Estimates of the annual prevalence state that 1-6% of the population will develop SAD with the larger prevalences ...

Phase N/A

Seasonal Affective Disorder and Visual Impairment

As a subtype of major depressive disorder, seasonal affective disorder (SAD) or winter depression causes severe reductions in both quality of life and productivity and results in high morbidity and frequent sick leave (1). SAD is a prevalent disorder with rates as high as 3-5% in central European countries and ...

Phase N/A

Influence of Light Exposure on Cerebral MAO-A in Seasonal Affective Disorder and Healthy Controls Measured by PET

This study aims to assess differences in monoamine oxidase A (MAO-A) distribution in the brain between seasonal affective disorder patients and healthy controls using positron emission tomography. In addition, the investigators aim to demonstrate the impact of light therapy on MAO-A distribution by investigating patients and controls in the winter ...
