They presented with irritability, physical aggression and mild cognitive impairment with intense emotional symptoms, and persecutory ideas and delusions. Two were wrongly diagnose as mania while the third was mimicking schizophrenia in its presentation. They received antipsychotic treatment and misdiagnosed as functional psychosis. They did not respond well to such treatment, until, series electroencephalograms were taken which revealed evidence of ictal psychosis. All, thence, responded well to addition of antiepileptic treatment. This, not only, proves to be effective, but also determined future management and prognosis. <strong>Conclusion: </strong>These cases shine light onto the role of the frontal cortex in the genesis of quasi-manic episodes and highlight the importance of EEG investigations in first episode of acute psychosis.展开更多
