EEG alpha power differences in the Icelandic winter between individuals with high vs. low risk for Seasonal Affective Disorder
Lada Zelinski, Yvonne Höller, Ragnar Pétur Olafsson · FENS Forum 2024
Frontal alpha asymmetry in Major Depressive Disorder has been widely examined in EEG research. Recently, the EEG has also been suggested as a potential diagnostic biomarker for Seasonal Affective Disorder (SAD), a recurrent Major Depressive Disorder with a seasonal pattern. However, thus far no studies have been conducted in the dark Icelandic winter to examine whether frontal alpha asymmetry can be detected also among individuals with elevated risk for seasonality. EEG data was recorded in 122 participants (34 men) during rest (3 minutes) in spring, summer, fall and winter in Iceland. At each
