Use of Bright Lighting in Senior Care Facilities Associated with Some Improvement in Dementia Symptoms

The use of daytime bright lighting to improve the circadian rhythm of elderly persons was associated with modest improvement in symptoms of dementia, and the addition of the use of melatonin resulted in improved sleep. “In elderly patients with dementia, cognitive decline is frequently accompanied by disturbances of mood, behavior, sleep, [...]

Bright Light plus Melatonin in Elderly Patients with Dementia

An inexpensive combination treatment has modest positive effects. Many patients with dementia have disturbed sleep–wake cycles along with deteriorating cognition, mood, and behavioral organization. These researchers investigated the effects of bright light and melatonin, two major synchronizers of the circadian pacemaker, in 189 residents of 12 Dutch assisted-care facilities. Facilities were [...]

A Seasonal Pattern of Hospital Medication Errors in Alaska

Specific behavioral consequences of seasonal affective disorder have not been closely examined. Length of daylight is evaluated in relation to medication errors in a medical center located in the far north. Factors such as numbers of patient admissions, discharges, and deaths were controlled with data collected in Anchorage, Alaska, over 5 [...]

Pediatric Seasonal Affective Disorder

OBJECTIVE: To evaluate the efficacy of light therapy for the treatment of pediatric seasonal affective disorder (SAD). METHOD: 28 children (aged 7 to 17 years) at two geographically distinct sites were enrolled in a double-blind, placebo-controlled, crossover trial of bright-light treatment. Subjects initially entered a week-long baseline period during which they [...]

ipRGC, the Newfound Eye Cells that Sense Night Day

The eye's retina contains light receptors known as cones and rods. These receptors receive light, convert it to chemical energy, and activate the nerves that send messages to the brain. They were thought to be the only photoreceptors in the retina. "When we began to do our work, we knew there [...]
