Filter by:This project aims to investigate (1) the efficacy of light therapy on internet gaming disorder (IGD); (2) the underlying neural mechanisms of such efficacy
The study would enroll depressed adolescents and adults with bipolar I or II disorder or major depressive disorder who are receiving stable psychiatric medication (excluding patients with hypomania or mania, mixed symptoms, or rapid cycling). Participants would be randomly assigned to treatment with either 1,0000-lux bright white light therapy in the morning or 1,0000-lux bright white light therapy in the afternoon, or <100-lux dim red placebo light therapy in the afternoon (N=59 for each group). Participants would be treated for 6 weeks. Symptoms would be assessed every two weeks with the 24-items Hamilton Depression Scale, the Young Mania Rating Scale, and the Pittsburgh Sleep Quality Index; salivary melatonin and cortisol concentrations will be also measured.
Sleep disorders are common in dialysis patients. At present, the management of insomnia in patients with chronic renal failure is not significantly different from that of the general population, which focuses on the management of co-factors, sleep hygiene, and cognitive-behavioral therapy. Light therapy is a paramedical practice that involves exposing a patient to a light intensity greater than 5000 Lux (usually 10,000 Lux) for 30 minutes in the morning between 7:00 and 8:30. Its impact is partly mediated by an improvement in the nycthemeral cycle of melatonin. Light therapy may improve sleep disorders and anxious-depressive elements as suggested in the literature. This technique has not yet been evaluated in dialysis patients, whereas easy to set up.
