Ask An Expert: Alzheimers

If I have gene testing, can I find out if I might be a carrier of Alzheimer's? One grandparent on each side of my family was diagnosed with it and both eventually died from Alzheimer's.

My mother has dementia. She's in an Alzheimer's facility and in a constant state of anxiety and depression. The number of medications she is on is incredible: Cymbalta, Depakote, Haloperidol, Aricept, Seroquel, Buspar, Trazodone, and Risperdal. They do not control her behavior. Is she at risk for dangerous drug interactions? How can I make sure her therapy is appropriately monitored?

My husband is experiencing increasing forgetfulness over simple things. He has had his thyroid tested (no problems). He doesn't get enough rest and he's under a lot of stress. He doesn't exercise either, and he's a bit overweight. Could these issues be contributing factors?

I have read that getting a flu shot more than five years in a row leads to a higher risk of Alzheimer's disease. Is this information valid?

About six months ago I noticed I can't smell common scents like fresh peaches. I have read about the correlation between declining sense of smell and Alzhiemer's disease. My memory has sometimes been faulty for the last few decades. What are the risks of my developing Alzheimer's, and should I consult my doctor about my loss of smell?

I have read that one cause of dementia can be an "adverse reaction to medication." Has Xanax been known to cause dementia?
