As it is known, dementia is a general term that refers to a group of disorders caused by abnormal changes and activity of the brain. These then lead to a loss of thinking ability and also affect a person’s memory, impairing their daily functioning.
According to Express.co.uk, Dr Sara Imarisio, head of research at Alzheimer’s Research UK, believes that “changes in the brain associated with dementia-causing diseases in the brain may begin 20 years before symptoms such as dementia appear.”
“One of the key early brain changes in Alzheimer’s disease is the production of amyloid proteins.
“While we can detect levels of this protein through expensive brain scans and other biological tests, not everyone with high levels of amyloid develops Alzheimer’s symptoms,” he added.
