One consequence of our ageing population is a sharp increase in the number of neurodegenerative brain diseases in later life.
It's important to note that Alzheimer’s disease and other dementias are not a part of normal aging.
However, dementia is more common in older people, especially over the age of 65.
There's no cure for dementia, only treatments which can sometimes prove effective in slowing its progression.
It was interesting to read today about a new 'wonder drug' in development which appears to have a powerful protective effect on the brain.
Human clinical trials are expected to begin soon, with the treatment available within two or three years.
Whilst these drugs are unlikely to represent a cure, they could prove effective in slowing the progression of neurodegenerative brain diseases like Alzheimer's disease.
"We're very unlikely to cure them completely, but if you arrest the progression you change Alzheimer's disease into something completely different so it becomes liveable with."
