Management of Psychosis Secondary to Seizure Disorder

Diagnostic Approach

Awareness and level of consciousness in psychotic patients are typically intact, according to the American College of Radiology 1, 2
Consider neuroimaging (CT head without IV contrast or MRI head without IV contrast) to exclude intracranial processes requiring intervention, as recommended by the American College of Radiology 1, 4
Distinguish from primary psychotic disorders (schizophrenia, bipolar disorder with psychotic features) and other secondary causes of psychosis, as suggested by the American College of Radiology and Praxis Medical Insights 2, 3

Risperidone at low doses (around 2 mg/day) is preferred due to lower risk of lowering seizure threshold, according to the British Journal of Psychiatry 5
Olanzapine (7.5-10.0 mg/day) is another appropriate initial option, as recommended by the British Journal of Psychiatry 5, 6
Avoid high initial doses of antipsychotics as they increase side effects without hastening recovery, as advised by Praxis Medical Insights 3

Include families in the treatment plan and provide them with emotional support and practical advice, as recommended by the British Journal of Psychiatry and Praxis Medical Insights 3, 5, 6
Provide psychoeducation to patients and families about the nature of seizure-related psychosis, treatments, and expected outcomes, according to the British Journal of Psychiatry 6

Maintain continuity of care with the same treating clinicians for at least the first 18 months of treatment, as recommended by the British Journal of Psychiatry and Praxis Medical Insights 3, 6
Monitor for depression, suicide risk, substance misuse, and social anxiety, which should be identified and actively treated, according to the British Journal of Psychiatry 6
