People with Alzheimer’s by this stage of the disease start to forget significant amounts of information about themselves and their surroundings. They may forget names of their spouses, require assistance dressing, require assistance bathing properly then require assistance with the mechanics of toileting. Urinary incontinence and disturbed patterns of sleep becomes a feature.
In severe Alzheimer's, speech ability becomes limited to just six or seven words and intelligible vocabulary limited to a single word. They lose the ability to walk, sit up, smile and eventually cannot hold up their head. The brain now appears unable to tell the body what to do.
