conditions/diseases that show similar symptoms as alzheimer's?

My father was first diagnosed with alzheimer's, but has now been told that he doesn't have the disease, but the doctor does not know what it is. Does anyone know of any other conditions or diseases that can have similiar symptoms?

He has seen both.

I did some research on that and these are the symptoms associated with it:
* shortness of breath
* fatigue
* pallor
* rapid heart rate
* loss of appetite
* diarrhea
* tingling and numbness of hands and feet
* sore mouth
* unsteady gait, especially in the dark
* tongue problems
* smell, impaired
* gums, bleeding
* positive Babinski's reflex
* loss of deep tendon reflexes
* personality changes, "megaloblastic madness"


My dad's symptoms are a little different. They include mostly confusion and forgetfulness

Oh,yes all that too,in some people,not all.............

Not all who have Alzheimer's have seizures,maybe 5% do........

For wide consumption, Lynne lives with the disease and is also a retired health professional. I hope folks who didn't know that will bear it in mind.

For the OP:
I would suggest having your father dx'd by a specialist in the dementing diseases. This is a sometimes arduous process of tests, interviews and the taking of a family geneological medical history. In our case, the process took about 3 months and a little over 100 hours of tests and intervews. The final dx was vascular dementia.

My mom is also hypothyrodic and changes in her thryroid meds definitely has improved her condition.

One question: Does your father routinely make new memory? Can he learn a new task?
