Exercise can help improve mood and overall symptoms of those who suffer from seasonal affective disorder (SAD).
Neurons in the suprachiasmatic nucleus coordinate to adapt to different lengths of daylight, changing at cellular and network levels. The neurons changed in mix and expression of dopamine, altering brain activity and subsequently daily routine behaviors.
Neuroimaging study reveals how light-sensitive signals reach the brain and how regions associated with mood process those signals. Some regions of the cerebral cortex associated with cognitive and mood processing show sensitivity to light intensity.
The seasonal duration of daylight influences the number of opioid receptors in the brain. The findings shed new light on a potential mechanism behind seasonal affective disorder.
Fish model study found a potential target for the treatment of seasonal affective disorder (SAD). Researchers implicated NRF2 in seasonal depression and reported celastrol may help in the treatment of SAD.
Seasonal affective disorder (SAD) affects over 10 million people in the US. Find out the symptoms and treatment options available.
A new study identifies the mechanisms behind neurotransmitters involved in circadian changes. The study has implications for chemical imbalances in the brain that can lead to mental health problems.
Researchers discover common and specific changes to the brain's gray matter in patients with major depressive disorder and social anxiety disorder.
A treatment shown to improve symptoms of SAD has proven to be effective for treating bipolar disorder. Researchers report a six week course of bright light therapy improves symptoms of depression and daily functioning for bipolar patients.
