Clinical Trials [1707 Associated Clinical Trials listed on BioPortfolio]

Out-patient Wake Therapy, Light Therapy and Sleep Phase Advance for Depression

Depressed patients miss a night of sleep (Wake Night), then sleep at predetermined times ending at their desired sleep time. Beginning the morning following their Wake Night, patients sit ...

Sleep, Wake and Light Therapy for Depression

The aim of this study is to determine if altering the pattern of one's sleep and having light therapy can speed up the treatment of depression. In the UK, the large majority of patients wi...

Light Treatment for Sleep/Wake Disturbances in Alzheimer's Disease

The aim of this study is to demonstrate the efficacy of timed exposure to bright light for the treatment of disturbed nighttime sleep and daytime wake in community-dwelling dementia patien...

Light Treatment to Shift-working Nurses

This project examines 1) the effects of appropriately timed bright light on adaptation (in terms of sleep and sleepiness) to three consecutive night shifts; and 2) the effects of such brig...

Light Therapy for Elderly Depression

The purpose of this study is to investigate the following two hypotheses: 1. Treatment with bright light improves their sleep, mood, concentration and self-sufficiency of elderly d...

Exposure to bright light biases effort-based decisions.

Secreted in the evening and the night, melatonin suppresses activity of the mesolimbic dopamine pathway, a brain pathway involved in reward processing. However, exposure to bright light diminishes-or ...

Appetitive Symptoms Differentially Predict Treatment Response to Fluoxetine, Light, and Placebo in Nonseasonal Major Depression.

We previously reported that morning bright light therapy is efficacious in adults with nonseasonal major depressive disorder (MDD), both on its own and in combination with fluoxetine. Given that appet...

Predictors of response to combined wake and light therapy in treatment-resistant inpatients with depression.

There is growing evidence for combined chronotherapeutic interventions as adjunctive treatments for major depression. However, as the treatments can be demanding, we need to identify predictors of res...

An Open Trial of Morning Bright Light Treatment Among US Military Veterans with Chronic Low Back Pain: A Pilot Study.

To examine the feasibility, acceptability, and effects of a home-based morning bright light treatment on pain, mood, sleep, and circadian timing in US veterans with chronic low back pain.

Night light intensity and women's body weight: Evidence from Nigeria.

The prevalence of overweight and obesity are increasing in many African countries and hence becoming regional public health challenges. We employ satellite-based night light intensity data as a proxy ...

Medical and Biotech [MESH] Definitions

Failure or imperfection of vision at night or in dim light, with good vision only on bright days. (Dorland, 27th ed)

Abnormal sleep-wake schedule or pattern associated with the CIRCADIAN RHYTHM which affect the length, timing, and/or rigidity of the sleep-wake cycle relative to the day-night cycle.

Relatively bright light, or the dazzling sensation of relatively bright light, which produces unpleasantness or discomfort, or which interferes with optimal VISION, OCULAR. (Cline et al., Dictionary of Visual Science, 4th ed)

Treatment using irradiation with light of low power intensity so that the effects are a response to the light and not due to heat. A variety of light sources, especially low-power lasers are used.

Light-induced change in a chromophore, resulting in the loss of its absorption of light of a particular wave length. The photon energy causes a conformational change in the photoreceptor proteins affecting PHOTOTRANSDUCTION. This occurs naturally in the retina (ADAPTATION, OCULAR) on long exposure to bright light. Photobleaching presents problems when occurring in PHOTODYNAMIC THERAPY, and in FLUORESCENCE MICROSCOPY. On the other hand, this phenomenon is exploited in the technique, FLUORESCENCE RECOVERY AFTER PHOTOBLEACHING, allowing measurement of the movements of proteins and LIPIDS in the CELL MEMBRANE.
