Diseases of the brain often produce both mental and physical symptoms. Patients with neurological conditions such as Alzheimer’s disease, frontotemporal dementia, Parkinson’s disease, stroke, epilepsy, multiple sclerosis, brain tumor, brain infection, or traumatic brain injury often experience cognitive, emotional, and/or behavioral problems as a consequence of their illness. To understand and help patients with complex neuropsychiatric illnesses like these a practitioner must have a good knowledge of both the mental and physical aspects of the illnesses. Psychiatrists who specialize in neuropsychiatry usually complete a general psychiatry residency and then complete one to two years of additional training in the assessment and treatment of patients with complex brain/mind illnesses. In the Neuropsychiatry Program at UIC we work with our colleagues in neurology, neuropsychology, neurosurgery, neurorehabilitation, and others to provide the best possible care for patients with complex illnesses that fall into the overlap area between the traditional specialties of psychiatry and neurology.
