Psychiatry: disorder groups
Neuropsychiatry (epilepsy, brain injury, movement disorders)
Neuropsychiatry deals with mental and behavioural problems caused by brain disease, such as epilepsy, traumatic brain injury, stroke, movement disorders and brain infections. Psychiatrists must recognise when symptoms are neurological in origin and treat them alongside neurologists.

What is it?
The brain is the organ of both neurology and psychiatry. When it is damaged or diseased, mood, behaviour, personality and perception can change. Neuropsychiatry focuses on these overlaps: depression after stroke, psychosis in epilepsy, personality change after head injury, apathy and hallucinations in Parkinson's disease, and psychiatric symptoms that are the first sign of autoimmune encephalitis.
Some conditions sit on the border, such as Tourette syndrome, catatonia and functional neurological disorder. Psychiatric medicines can also affect the nervous system, for example lowering the seizure threshold or causing movement disorders.
Neuropsychiatry is a specialised field, but every psychiatrist needs enough knowledge to avoid missing a neurological cause and to work closely with neurologists.
Why does a psychiatrist need it?
Missing a brain cause of psychiatric symptoms can be dangerous. Psychiatrists need neurological examination skills, knowledge of when to request brain imaging, EEG or a lumbar puncture, and familiarity with prescribing safely in epilepsy and brain injury. This area is tested heavily in MRCPsych Paper A and in MMed examinations.

Common questions
Can epilepsy cause psychiatric symptoms?
Yes. People with epilepsy have higher rates of depression and anxiety, and some develop psychosis around or between seizures. Some anti-epileptic medicines can also affect mood.
Why do psychiatrists learn neurology?
Because brain diseases can first appear as changes in mood, behaviour or thinking. Recognising these causes prevents misdiagnosis and harm.
