Is bright light therapy useful for depressive symptoms in patients with BD?
After a week of baseline measurements, patients received 2 hours/day of exposure to bright light between 7:00 p.m. and 9:00 p.m. for 1 week. During the baseline week, the treatment week, and a posttreatment week, patients were rated by nurses for agitation, sleep-wake patterns, use of restraints, and use of prescribed-as-needed medication.

What is bipolar disorder?
Bipolar Disorder (BD) is a complex, chronic, sporadic mood disorder [ 1, 2 ].It affects more than 1% of the world's population, and studies have shown that the total lifetime prevalence rates of BD I and II are 0.6%,and 0.4% respectively [ 3 – 6 ]. Formerly known as manic depression, BD is a serious chronic mood disorder characterized by manic episodes, hypomania and alternating or intertwined depressive episodes. Among these manifestation, depressive episodes are the most common, accounting for more than 50% of patients with BD [ 7, 8 ]. BD is complicated, and the rates of misdiagnosis and missed diagnosis are high. The most widely acknowledged diagnostic classifications are the 10th revision of the International Classification of Diseases (ICD-10) and the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) [ 9 – 12 ]. Some studies have found that patients with BD make serious suicide attempts, and the annual mortality rate is higher than that of the general population [ 7, 13 – 15 ]. Therefore the main purpose of treating depressive symptoms in BD is to quickly reduce disease severity and prevent suicide, which is considered the main challenge in long-term treatment [ 16 – 18 ]. Mood stabilizers and antipsychotics are the mainstays of acute treatment for mania and depression in BD [ 19 ], and lithium is considered to be one of the most effective treatments for preventing both types of symptoms [ 20 ]. However, given the high rate of recurrence of BD, these strategies can lead to complications such as nephrotoxicity or liver damage [ 21 – 23 ].
Is BLT good for bipolar?
Recently, some studies have shown that bright light therapy (BLT) seems to be useful for BD depression. This meta-analysis is intended to further elucidate the role of BLT in depressive symptoms in patients with BD.
What is BD in medical terms?
Formerly known as manic depression, BD is a serious chronic mood disorder characterized by manic episodes, hypomania and alternating or intertwined depressive episodes. Among these manifestation, depressive episodes are the most common, accounting for more than 50% of patients with BD [ 7, 8 ].
What is BLT therapy?
Bright light therapy (BLT), also called phototherapy, refers to the use of glare therapy to treat depressive symptoms [ 24 ], BLT was originally used to treat patients with seasonal affective disorder [ 25 – 29 ]. Numerous studies indicate direct and indirect effects of light on mood.
What is the best treatment for BD?
Mood stabilizers and antipsychotics are the mainstays of acute treatment for mania and depression in BD [ 19 ], and lithium is considered to be one of the most effective treatments for preventing both types of symptoms [ 20 ].
What are the inclusion criteria for BLT?
The inclusion criteria were: (1) randomized controlled trial (RCT) or cohort study on the effects of BLT on depressive symptoms in patients with BD; (2) clearly defined diagnosis of BD. The exclusion criteria were: (1) data were incomplete or could not be extracted, (2) study subjects included pregnant women.
What is meta analysis?
Meta analysis was performed with RevMan 5.3 software. A meta-analysis aggregates indexes of effectiveness of individual trials into one pooled estimate. When the result is a continuous variable, then the effect size is usually expressed as mean difference (MD) or normalized mean difference (SMD).The outcome measure was analyzed using standardized mean differences (SMD). The MD is the difference in the means of the treatment group and the control group, while the SMD is the MD divided by the standard deviation (SD) [ 49 ]. Meta-analysis of trials that have used different continuous or rating scales to record outcomes of a similar nature requires sophisticated data handling and data transformation to a uniform scale, the standardized mean difference (SMD) [ 50 ].The measurement data adopt the standardized mean difference (SMD) as the effect index, and each effect quantity gives its point estimate and 95% confidence interval (CI). Heterogeneity among included studies was analyzed using χ2 tests (a = 0.1), and the magnitude was quantified in conjunction with I2. If there was no statistical heterogeneity between study results, a fixed effect model was used for meta-analysis; if there a random effect model was employed. Studies with obvious clinical heterogeneity were included in subgroup or sensitivity analysis, or only descriptive analysis [ 51 ]. In the first step, we conducted a separate meta-analysis of RCTs and cohort studies. To explore possible confounding effects of clinical variables, we also performed subgroup meta-analysis of studies based on different treatment parameters, including other auxiliary measures, light intensity and concomitant medication.
What is the goal of bright light therapy?
In general terms, the goal of bright light therapy is to provide exposure to bright light at a level of intensity and schedule of administration that combines the greatest levels of therapeutic benefit with the lowest levels of cost in terms of time and negative effects.
Is bright light therapy safe for dementia patients?
This article provides clinicians with a summary of the neurophysiology of bright light therapy, bright light research considerations, an evidence-based bright light protocol, problems related to bright light therapy, and clinical implications for bright light therapy in older adults with dementia. Bright light exposure is a safe, non-pharmacological treatment that is currently underutilised in this population. Clinicians may find bright light therapy beneficial as a primary or adjunctive treatment in reducing depression and agitation in older adults with dementia.
What is the wavelength of light?
As a source of neural stimulation, through its action on the retina, the wavelength of visible light ranges from 380 nm (violet in colour) to 760 nm (red in colour). When used therapeutically, bright white light comprises a mix of all wavelengths across this portion of the electromagnetic spectrum. It is also called ‘full-spectrum’ light. The intensity of light hitting the retina can vary widely at different times of day and in different indoor and outdoor settings. For example, the intensity of light typically ranges from a high of approximately 100 000 lux during the brightest part of a sunny day outdoors, to 7000–12 000 lux outdoors at dawn (Shirani#N#Reference Shirani and St Louis#N#2009) to 200–1000 lux indoors (Shirani#N#Reference Shirani and St Louis#N#2009; Landry#N#Reference Landry and Liu-Ambrose#N#2014 ).
Does bright light help with affective disorder?
The way in which bright light therapy improves non-seasonal affective disorder is not understood; however, theories draw from the body of knowledge of circadian rhythms and seasonal affective disorder, which have been studied more extensively (Paino#N#Reference Paino, Fonseca-Pedrero and Bousoño#N#2009; Vadnie#N#Reference Vadnie and McClung#N#2017 ). Bright light treatment appears to be effective when used as a first-line treatment or as an adjunctive therapy combined with pharmacological intervention (Golden#N#Reference Golden, Gaynes and Ekstrom#N#2005; Crowley#N#Reference Crowley and Youngstedt#N#2012; Ekström#N#Reference Ekström and Beaven#N#2014 ). Bright light exposure improves daytime alertness, reduces fatigue and improves sleep, thus countering symptoms of depression (Crowley#N#Reference Crowley and Youngstedt#N#2012; Ekström#N#Reference Ekström and Beaven#N#2014 ). One possible mechanism to explain the relationship between bright light therapy and depression is that bright light therapy causes changes in the production of serotonin and melatonin, which in turn alters plasma levels of serotonin and melatonin, resulting in reduced levels of depression (Shirani#N#Reference Shirani and St Louis#N#2009 ).
Does dementia have circadian rhythm?
Dementia may have a circadian rhythm component, as manifested by ‘sundowning’ (changes in behaviour at dusk) (Paino#N#Reference Paino, Fonseca-Pedrero and Bousoño#N#2009; Hanford#N#Reference Hanford and Figueiro#N#2013 ). Although the normal ageing process results in decreased cell volume and numbers in the SCN, in individuals with Alzheimer's dementia this effect is amplified (Yang#N#Reference Yang and Schmitt#N#2001; Hanford#N#Reference Hanford and Figueiro#N#2013; Landry#N#Reference Landry and Liu-Ambrose#N#2014 ). Bright light therapy may improve depression and agitation in older adults with dementia by directly influencing the circadian aspects inherent in the disease process or by improving the sleep–wake cycle, decreasing daytime napping, increasing restful night-time sleep and increasing plasma levels of serotonin (Shirani#N#Reference Shirani and St Louis#N#2009; Hanford#N#Reference Hanford and Figueiro#N#2013; Landry#N#Reference Landry and Liu-Ambrose#N#2014 ).
