hi angela my dad had it just before he died and i think my uncle may be starting with it. my sister doreen is caring for her mother in law after she broke her hip 3 months ago and now the mother in law doesnt recognise our doreen or her son roger, she asked who her son was and wouldnt believe it when they said -your son- in the hospital. senile dementia symptoms are more or less similar to this arent they.
