‘Flashing light therapy’ for Alzheimer’s

A flashing light therapy competence assistance sentinel off Alzheimer’s, contend US scientists after promising trials in mice.

The Massachusetts group found resplendent a strobe light into rodents’ eyes speedy protecting cells to cackle adult a damaging proteins that amass in a mind in this form of dementia.

The ideal rate of flashes was 40 per second – a frequency obvious flicker, 4 times as quick as a disco strobe.

The researchers contend a proceed should be tested in humans.

They are already seeking accede from a US regulator, a Food and Drugs Administration, and have set adult a blurb association to rise a technology.

Sticky plaques

Build-up of beta amyloid protein is one of a beginning changes seen in a mind in Alzheimer’s disease.

It clumps together to form gummy plaques and is suspicion to means haughtiness dungeon genocide and memory loss.

Researchers have been looking for ways to forestall board arrangement regulating drugs, though the formula have been disappointing.

Amyloid plaques are a hallmark of Alzheimer’s disease

But Dr Li-Huei Tsai and colleagues during a Massachusetts Institute of Technology consider they have found another way, regulating light.

The mice that they complicated were genetically engineered to have Alzheimer’s-type repairs in their brain, Nature biography reports.

When a mice were put in front of a flashing light for an hour, it led to a conspicuous rebate in beta amyloid over a subsequent 12 to 24 hours in a tools of a mind that hoop vision.

Doing this each day for a week led to even larger reductions.

Likewise, light kick approach to a partial of a mind that deals with memory – a hippocampus – led to reductions of beta amyloid there.

The researchers contend a light works by recruiting a assistance of proprietor defence cells called microglia.

Microglia are scavengers. They eat and transparent damaging or melancholy pathogens – in this instance, beta amyloid.

It is hoped that clearing beta amyloid and interlude some-more plaques from combining could hindrance Alzheimer’s and a symptoms.

Dr Tsai said: “We are optimistic.”

The scientists say, in a future, people could wear special goggles or lay in front of a light-emitting device to get a healing sip of a strobe light.

For a patient, it should be wholly painless and non-invasive.

“We can use a really low intensity, really ambient soothing light.

“You can frequency see a flutter itself.

“The set-up is not descent during all,” they said, stressing it should be protected and would not trigger epilepsy in people who were susceptible.

Dr David Reynolds, of Alzheimer’s Research, UK said: “Studies like this are profitable in divulgence new processes concerned in Alzheimer’s illness and opening new avenues for serve research.

“While mice used in this investigate showed some pivotal facilities of Alzheimer’s, it is always critical to follow adult these commentary in people.”
