Who should i talk to if i am worried that my parent has alzheimer's disease?

PCP: Talk to his/her primary care physician, the doctor will be able to help with diagnosis, treatment and other options.

Doctor: Schedule an appointment with your mom/dad's doctor and go with them to the appointment to discuss your concerns.

Start with them: If the person doesn't believe they have a problem, you might want to enlist the aid of your siblings or friends of your parent. Ideally you can go with them to a doctors appointment. If they are opposed to this you may need to send a letter to the doctor. Give specific examples of statements and actions that concern you.
