When to Contact a Medical Professional

Contact your regular health care provider or a doctor who treats disorders of the nervous system (neurologist) if:

• The unusual or strange behavior is severe, long-term, unexplained, or is affecting your life
• You have dementia or delirium

The health care provider will perform a physical examination and will take a medical history. The physical examination will probably include a detailed evaluation of the nervous system (neurological evaluation).

Medical history questions may include:

• What unusual behaviors are present?
• How much is the lifestyle affected?
• Can the person eat, dress, and perform other everyday activities?
• When did the unusual behavior begin?
• Is it getting worse, better, or staying about the same?
• How fast is the behavior changing?
• What other symptoms are present?

The following tests may be performed:

• Blood tests
• CT scan of the head
• Mental status test
• Other neurological tests
