Alzheimer’s disease is the commonest dementia that we know. Again it’s a disease of the brain that’s associated with ageing. There are some rare or genetic forms that affect younger people but generally it’s a disease that hits people over the age of 60.
The common clinical presentation of people with Alzheimer’s is clearly a memory problem. Losing and forgetting either things or information, like placing your spectacles around the house, leaving taps running, repeated questioning, not remembering what happened today but having a great memory for what used to be in the past and that’s where we find these difficulties that patients have with Alzheimer’s disease presenting very floridly and not being able to remember new information.
