Overmedication, dehydration, and major depression can all look like Alzheimer's in an elderly person. All of these are treatable. If you are concerned, ask your primary healthcare provider about a referral to a neurologist or neuropsychologist. Other dementias are usually easier to diagnose. The second leading cause of dementia is dementia due to strokes.
People can develop dementia from long misuse of drugs or alcohol.
Also at risk are people who inhale paint or other poisonous substances to get high. Many people who fear that they are losing their memories refuse to go to the doctor because they do not want their fears confirmed. However, what you may get is news that the problem can be treated.
