I have been taking lorazepam for almost 17 years(most of that time I believe I was taking at least 2-3 mg per day). The last few years I've been taking 5 mg per day. Now I'm taking 4 mg per day. I'm 39 years old and I'm worried about getting Alzheimer's. I 'm mostly worried about getting early onset Alzheimer's. I don't have any early onset Alzheimer's in my family and I know it's usually a genetic disease. Does everyone taking the amount of lorazepam I'm taking and the length I've been taking it going to get early onset Alzheimer's or the old age type of Alzheimer's? I'm afraid. Any suggestions? I'm taking lorazepam for OCD and to sleep better.
