My mom is nearly 70 and she's going senile. It's not showing as confusion or forgetfulness that you would associate with dementia. There is some mixing up of names and forgetting things but so far it's very mild and hardly noticable.
There's other things going on with her. It's all so hard to explain. Basically since the beginning of this year, I am pieceing together bits and pieces of her behaviours and I think dementia might be setting in with her. She's different every day. Some days she is better than others thank other days there's something up with her. It's hard to explain and pinpoint.
