Is it possible for a 85 year old person to suffer cognitive memory loss as a result of a fall.  She fell and hit her head while on vacation in Europe 2 years ago and had two black eyes as a result.  Ever since then my mom has had trouble with her memory.  Her doctor says it is not dementia or alzheimers but I dont think he knows about the fall.
HIT hanks for using Chat Doctor Yes, it is possible. Sometime due to head injury, internal damage happens, that would lead to memory loss. In that case, patient has also some physical complaints in form difficulty in walking etc. If there are not in your mother case and still she has memory loss, that may be due to mild cognitive impairment. This is early stage of dementia. In case, you have more query, you can ask. Thanks
