An association between epilepsy and psychosis has been demonstrated in various reviews, and it has been estimated that psychosis in the form of schizophrenia affects between 3% and 7% of all epileptic patients. Lacosamide an anti-epileptic was synthesised and used for treatment of epilepsy as well as neuropathic pain. Psychosis is not included as a common adverse effect of the drug. The mechanism by which psychosis is associated with lacosamide is not yet known and is not known to modulate serotonin or dopamine systems. Literature review shows only a few cases reported with similar presentations. We present here a case of a 38 year old male; with Lacosamide induced psychosis.
