Seen many psychiatrists for decline in memory then loss of speaking skills then increased tremors and lightheadedness on the left side , my syndrome ?

Neuropsychiatrist?: I don't know who you've seen in the past, but it may help to see a neuropsychiatrist at a major medical center. Many medical schools have departments focused on people who suffer from rare, difficult-to-diagnose neurological & neuropsychiatric conditions. Your needs may be exceeding the expertise of psychiatrists in your community alone. Ask them for referral to a tertiary medical center.
