Question
My father had his left leg amputated 2 week's ago. Doctors had Peripheral Vascular Disease on his leg before amputation as his toes became gangrenous. After the operation, he became delirious and could not remember some family members. Is this normal?

Answer
Hello CP,

Yes, quite normal that your father had a Delirium episode.  Don't confuse Delirium with Dementia.  

Dementia are symptoms of of brain DISEASES such as:  Alzheimer's, Parkinson's, etc.   Delirium is an acute episode of forgetfulness, "fogginess", etc. that may last a few days.  Think back to when you had the flu...now multiply it's intensity alittle further; however, it subsided and you were once again yourself.

Between the intense infection in your father's toes and the anesethia from the operation, i'd say he was very lucky to have family so attentive to him.

I know everyday will be a day better for him.
