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

The following is a case of a 29-year-old patient with a previous major depressive episode comorbid with CLIPPERS. Following glucocorticosteroid therapy, the patient switched to mania-like presentation and was diagnosed with bipolar disorder due to another medical condition. So it is strongly suggested that high-dose corticosteroid pulse therapy could easily induce psychiatric disturbances for patients with previous psychiatric symptoms, and there may be potential links between bipolar disorder and CLIPPERS in the area of infammation.展开更多

This study investigates the efficacy of pharmacological interventions and rehabilitation strategies to improve patient outcomes and quality of life. Utilizing a randomized controlled trial with multiple treatment arms, participants will receive pharmacotherapy, polypharmacotherapy, rehabilitation interventions, or combination treatments. Outcome measures will be assessed using standardized scales, including the Hamilton Depression Scale, Yale-Brown Obsessive Compulsive Scale (Y-BOCS), and Mania Scale. Preliminary data suggest improvements in symptom severity and functional outcomes with combination treatments. This research aims to inform clinical practice, guide treatment decisions, and ultimately enhance the quality of care for individuals living with bipolar disorder. Findings will be disseminated through peer-reviewed journals and scientific conferences to advance knowledge in this field.展开更多
