Midday Light Therapy May Improve Depressive Symptoms in Patients With Bipolar Disorder

Adjunctive bright light therapy may help lower depressive symptoms in adults with bipolar disorder, reports astudy published yesterday inAJP in Advance.“Despite advances in drug treatment for mania, the development of effective pharmacotherapy for bipolar depression remains a challenge,” wrote Dorothy Sit, M.D., of the University of Pittsburgh and colleagues. “Given the limited treatment options, research to investigate novel therapeutics for bipolar depression is a high-priority public health concern.”Much like patients with major depression, people with bipolar disorder commonly report sleep problems and lethargy, which suggests they may have disrupted circadian rhythms. These circadian problems could benefit from light therapy. The study included 46 adults with bipolar I or II disorder with symptoms of major depression (Structured Interview Guide for the Hamilton Depression Scale With Atypical Depression Supplement [SIGH-ADS] score of 20 or more), but not mania or mixed symptoms. These patients were randomly assigned to either a 7,000-lux bright white light or 50-lux dim red placebo light unit, which they agreed to use daily at home or work. All patients started with a 15-minute light session between noon and 2:30 p.m. that increased by 15 minutes each week to a target dose of 60 minutes daily. Sit and colleagues chose midday light since it tends to have a subtler effect on circadian rhythms, allowing for better mood with less risk of slee...

Abstract Patient diurnal mood fluctuation, sleep characteristics and factors affecting sleep homeostasis predict antidepressant response to the combination of total sleep deprivation and light therapy (TSD + LT). In order to study if chronotype could influence response to TSD+LT, we considered 194 bipolar depressed patients. Severity of depression was rated with Hamilton Depression Rating Scale; perceived mood levels were assessed by a self-administered 10-cm visual analogue scale and chronotype was assessed using the Mornigness-Eveningness Questionnaire. More than 60% of patients resulted responders to ...

The use of light for its antidepressant action dates back to the  beginnings of civilization. As early as 4700 y ago, Wong Tai mentioned the fluctuation of diseases with seasons, Hippocrates wrote on the interrelation between seasonal climates and mood (melancholia and mania) [1], and Aretaeus of Cappadocia prescribed, in the second century AD, that “Lethargi cs be laid in the light, and exposed to the rays of the sun, for the disease is gloom”. While being reported for millennia, bright light therapy (BLT) in depression was not officially recognized until 30 y ago for treating the Seasonal Affec...

Our society tends to dismiss seasonal affective disorder (SAD). We minimize it. We misunderstand it. Oh, you just don’t like winter. And who could blame you? Winter is tough on everyone. Oh, SAD is like the winter blues, right? You get grumpy or moody because you hate the freezing cold. You’re just in a funk. It happens to a lot of people. It’s totally normal. How can you feel depressed when the air is so crisp and it’s a winter wonderland out there? We incorporate SAD into our vocabulary, flippantly using it in conversation. “Similar to someone saying “I can’t make up my mind, it...

The combination of three cycles of sleep deprivation (SD), light therapy (LT), and lithium has recently been proposed as a possible first-line treatment for bipolar depression. However, it is unclear whether early improvement predicts final response/remission in bipolar depression treated with this regimen.

It’s that time of year again when the highly sensitive types among us who thrive with lots of sunlight begin to wither with the plants as the sun begins to hide. Not only do we get less vitamin D (and deficiencies have been linked to depression), but the change in sunlight affects our circadian rhythm — the body’s internal biological clock that governs certain brain activity and hormone production. In some people, the change of mood-related chemicals can cause seasonal affective disorder (SAD), also known as winter blues or seasonal depression. For an episode of major depression to be class...

By Christian Jarrett The clocks have gone back and there’s a chill in the air. It’s well known that during these darker months, a significant minority of us experience unwelcome negative changes to our mood (at least if you believe in the notion of Seasonal Affective Disorder or SAD, which not all experts do). Now an intriguing study in Psychiatry Research has explored the link this condition may have with another psychiatric diagnosis, Obsessive Compulsive Disorder (OCD). The results suggest that people with OCD are more likely than average to experience seasonal effects on their mood, and that for these ...

Authors: Benedetti F, Poletti S, Hoogenboezem TA, Locatelli C, de Wit H, Wijkhuijs AJM, Colombo C, Drexhage HA Abstract BACKGROUND: The clinical relevance of raised levels of circulating cytokines in bipolar disorder is still unclear. Cytokines influence neurotransmitters, neuroplasticity, and white matter integrity. An inconsistent literature suggests that higher cytokine levels could hamper antidepressant response. Total sleep deprivation (TSD) and light therapy (LT) prompt a rapid antidepressant response and can provide a model treatment to study predictors of response. METHODS: We studied at baseline 15 imm...
