The brain changes behind Alzheimer’s
Current evidence suggests that Alzheimer’s disease is caused by the abnormal build-up of proteins in and around the brain.
Known as amyloid and tau proteins, the NHS added that there’s also a decrease in the chemical messengers (i.e., neurotransmitters) in the brain.
“Levels of one neurotransmitter, acetylcholine, are particularly low in the brains of people with Alzheimer’s disease,” the NHS stated.
