My brother is in trouble.  On Father's Day, he wanted to call my Dad and wish 
him a happy day -- my Dad died in 1996.  Recently, he (brother) was on his way 
to a location very near where he lives -- and ended up in a town four towns 
away.  On Tuesday night of this week, he called my Mom and asked her "Mom, is 
my 
Dad dead?  When did he die?"  So he is having serious memory issues, both 
recent 
and distant memory is involved.

Of course, he's seeing doctors and being tested, and they don't know what's 
going on with him.  He's been tested for Alzheimers, and they tell him he 
doesn't have it.  The doctors also tell him that this is not seizure-related -- 
my brother is an epileptic, and his seizures are controlled by medication.  
He's 
had brain scans and MRI's and no abnormalities are found.  They did find a 
small, non-malignant tumor on the brain, behind his left ear, but told him that 
is not life-threatening and is not involved in the memory issues.

So -- does anyone have any ideas about what could be going on with him?  Any 
help will be appreciated.
