Light therapy improves sleep and psychobehavioural symptoms in patients with Alzheimer's disease: Study
China: Light therapy significantly improves sleep and psychobehavioral symptoms and leads to relatively fewer side effects in patients with Alzheimer's disease, a recent study published in PLOS One has revealed.
The cognitive decline associated with Alzheimer’s disease is often accompanied by sleep disturbances and psycho-behavioral symptoms including apathetic and depressive behavior, agitation and aggression. Photobiomodulation is a non-pharmacological therapy that uses light energy to stimulate the suprachiasmic nucleus (SCN), a sleep modulator in the brain. Despite light therapy receiving increased attention as a potential intervention for Alzheimer’s, a systematic evaluation of its efficacy and safety has been unavailable.
In the new study, Qinghui Meng of Weifang Medical University, China, and colleagues searched multiple research databases to identify all randomized controlled trials related to light therapy intervention for Alzheimer’s disease or dementia. Fifteen high-quality trials with available methods and relevant outcomes were selected for further analysis. The included trials were written in English, published between 2005 and 2022, and performed in seven countries. They included a combined 598 patients.
