Dealing with Extreme Anger and Frustration in Early Onset Alzheimer's

Many years ago, I was diagnosed with Bipolar II, rapid cycling. It has been controlled for years with no relapses. Two years ago I started falling for no reason. I wasn’t dizzy like vertigo, I felt off balance on my feet and eventually had to bounce off the hallway walls and steady myself on furniture and countertops as I walked through the house. After years of tests (MRI’s, CAT scans, PET scans, DAT Scans [to diagnose Parkinson’s], large volume lumbar punctures, I was still undiagnosed and I was frustrated and angry. About 9 months ago, I had lost all muscle tone in my core and couldn’t get out of bed on my own. There was a period of months that I couldn’t take care of myself at all. That was when a “working diagnosis” was made. I was first diagnosed with Early Onset Alzheimer’s Disease. At 64, I was devastated! This diagnosis was supposed by two neurologists. My personal neurologist said he disagreed saying that his diagnosis was Mild Cognitive Deficit. He did warn that it most likely would progress to Alzheimer’s. I’m doing much better. I’m able to care for myself. I’ve begun driving again and (don’t tell my physical therapist!) I rarely use a walker or a cane. So what’s wrong? Extreme anger and frustration! Foul- mouthed especially when I’m angry or frustrated. The smallest irritation or frustration will send me over the edge, throwing things (never at anyone!) and cussing like a sailor! I have NEVER acted like this. I’ve dropped a note to my psychiatrist, but it’s Sunday and I won’t get an answer until next week. Are different drugs the answer? I don’t know. Have any of you experienced anything like that? What happened? Did you improve? How?
