Light Therapy Could Protect the Brain in Alzheimer’s disease

In 2016, scientists at Massachusetts Institute of Technology (MIT) in Cambridge discovered that shining a shining light into the eyes of mice could diminish the toxic buildup of amyloid and tau proteins that occurs in the brain with Alzheimer’s disease.

A light therapy increases a form of brain wave known as gamma oscillation, which research states that it remains weakened in people with Alzheimer’s disease. Very recently, the MIT team disclosed that merging light therapy with sound therapy expanded the beneficial effects even more.

The studies also noticed that light therapy can ameliorate memory in mice that are genetically disposed to develop Alzheimer’s disease and spatial memory in older mice without the condition.

The most recent inquiry, which has been featured in the journal Neuron, has shown that increasing gamma oscillations can boost the connection between nerve cells, reduce inflammation, and protect against cell death in mouse models of Alzheimer’s. It also revealed that the treatment’s far-reaching outcome includes not only nerve cells, or neurons, but also a type of immune cell called microglia.

Alzheimer’s is a condition that moderately kills brain tissue and related function through the irreparable loss of cells.

A 2018 report by Alzheimer’s Disease International showed that 50 million people worldwide have dementia, and for two-thirds of them, Alzheimer’s disease is the cause. Even though some treatments can slow down Alzheimer’s symptoms for a while, however, it can’t cure the condition.

For Alzheimer’s patients, the brain starts to change from a long time before they experience symptoms of dementia. Such symptoms consist of difficulties with thinking and remembering.

Two alterations in particular are the evolution of toxic deposits, or plaques, of beta-amyloid protein between nerve cells, and the creation of toxic tangles of tau protein inside the cells.

As per reports, it was seen that mice who received light therapy before the neuron degeneration showed remarkable improvements. Even those who are not genetically predisposed to Alzheimer have showed improved performance. Hence, light therapy can be helpful in treating Alzheimer.
