My mother is only 64 years old and already showing signs of dementia/Alzheimer's. She hasn't been officially diagnosed as we are still in the process of getting her in with a Neurologist. She experiences hallucinations, very depressed (cries constantly), increased short term memory loss such as not recognizing her home (she's lived there 14yrs but constantly says she wants to go "home"), unable to cook for herself( doesn't remember how) and lately has been urinating in random places (can't remember where the toilet is). She's also experiencing aphasia. Her cognitive skills seems to be declining rapidly. She is the youngest of 13 children and 3 of her siblings who are much older have already been diagnosed (they live out of the country). Forgive my ignorance but I was under the impression dementia/Alzheimer's affects people who are much older. Could it be something else? Her doctor has checked her blood/urine and everything comes back normal.
