For Alzheimer's Disease "I have taken Namenda and Aricept for years. Memory has improved! I have had the vivid dreams others have described, also muscle cramps. I am going to cut back on the Aricept and see if it helps...although I usually enjoy my dreams!"

For Alzheimer's Disease "I was taking Aricept to help preserve my memory, due to the fact that I am 46 years old. I had brain surgery in 2009 to prevent seizures, and now my memory is very bad. I took this medicine for about 2 months, but the vivid dreams and leg cramps were just too much to handle. I am trying a new Alzheimer's medicine now. I believe every medicine has side effects, we just have to pick and choose!"

For Alzheimer's Disease "I have been taking 5 mg each night with similar side effects as mentioned in other reviews: leg cramps and wild dreams. I've only been on the medicine for 3 months, but I have recognized a positive difference. I still function fairly well with driving, chores, working out, cooking, etc., but definitely can tell that my life is progressively changing. I encourage everyone reading these reviews to support your local and national Alzheimer Association groups. It's a horrible disease and life changer for families."

"Trouble sleeping resulting in headaches caused by 'abnormal' dreams listed in less common side effects. For me, the better definition is intense dreams, awaking with a headache and difficulty sleeping thereafter."
