Neuropsychiatry

Neuropsychiatry studies and treats mental and behavioral disorders associated with diseases or dysfunction of the brain and nervous system.

Psychiatry: The medical specialty concerned with diagnosing, treating, and preventing mental disorders. Neuropsychiatry applies psychiatric methods to disorders linked to brain and nervous-system dysfunction.
Delirium: An acute, fluctuating disturbance in attention and awareness caused by an underlying medical condition. It illustrates how brain dysfunction can rapidly alter cognition and behavior.
Neurotransmitter: A chemical messenger released by neurons to communicate with other cells. Changes in neurotransmission can contribute to symptoms and inform medication choices.
Behavioral neurology: A neurological subspecialty focused on cognitive and behavioral consequences of brain disease. It overlaps closely with neuropsychiatry but is generally rooted in neurology.
Theodore Meynert: A nineteenth-century Austrian psychiatrist and neuroanatomist who studied the brain's structure and psychiatric illness. His anatomical approach helped establish a tradition linking mental illness to brain organization.
Neurology: The medical specialty concerned with diseases of the brain, spinal cord, and peripheral nerves. Neurological examination and diagnosis help identify disorders underlying psychiatric symptoms.
Dementia: A syndrome of acquired cognitive decline that interferes with independent daily functioning. Neuropsychiatric care addresses its cognitive, emotional, and behavioral symptoms.
Neuroinflammation: Inflammatory activity within the brain or nervous system involving immune cells and signaling molecules. Inflammatory processes can affect neural function and accompany psychiatric symptoms.
Clinical neuropsychology: The professional application of psychological methods to assess and support people with brain-related cognitive difficulties. It contributes assessment and rehabilitation rather than medical diagnosis and prescribing.
Carl Wernicke: A German neurologist and psychiatrist known for research on language, brain lesions, and mental disorders. His work connected specific brain dysfunctions with changes in language and behavior.
