All of these can be signs of Alzheimer's but they can all be signs of other problems as well. A healthcare provider should evaluate the patient before it is assumed that he or she has Alzheimer's. There is no cure for Alzheimer's Disease or medications that really seem to halt the disease. Some new drugs are being tested. There are medications that help with sleeplessness, restlessness, and other signs.
Some medications seem to help memory in some people.
This is natural. It is very important that these people make plans for their illness, such as making a living will, appointing a durable power of attorney for healthcare, and making a will while they are still able. People usually live for 8-10 years after the diagnosis is made. Everyone involved in caring for an Alzheimer's patient will need information and support. Many workshops and support groups are available.
