New Research Could Mean Breakthrough For Alzheimer’s Sufferers

There has been a breakthrough in Alzheimer’s research, with scientists showing stimulating areas of the brain could restore memory. 

A recent study involving mice saw light pulses being used to stimulate an area deep within the brain (the supramammillary nucleus), followed by exposure to a chemical, to see whether this combination could help new nerve cells develop.

It showed that memory and cognitive abilities were partially restored in mice with symptoms of Alzheimer’s disease. The experiments also revealed immune cells were able to break down amyloid plaques, which are a feature of dementia, through the treatments. 

Head of strategic initiatives at Alzheimer’s Research UK Dr Sara Imarisio said: “By using a combination of light pulses and exposure to nerve-stimulating chemicals, the researchers were able to activate specific nerve cells deep in the brain, partly restoring memory and emotional functions.”

While she recognised there are differences between mice and human brains, she noted these studies “bring us closer to ways to effectively treat, and even cure, the disease”. 

This is, therefore, great news for those suffering with dementia, as there could be an effective treatment in the future that reverses their symptoms and brings back their memories. 

According to Alzheimer’s Society, there were 900,000 people with dementia in the UK in 2019. However, this figure was expected to rise to 1.6 million by 2040, if no medical advances are made before then. 

Nearly two-thirds (60 per cent) of people who require home care support are those with dementia.
