Organic manic syndrome: causative factors, phenomenology and immediate outcome
Abstract:
A prospective study on organic manic syndromes led to identification of 30 cases over a period of 11 months, constituting 1.75% of all admissions and 4.67% of all patients with mania. They were compared with 60 sex- and age-matched bipolar controls. The mean age of onset of illness was not significantly different in the two groups. Family history of affective disorder was more often negative in organic manics. The overall mania rating score was similar in the two groups, but after 3 months organic manics improved less. Compared to the bipolar group, organic manics were more often irritable, made threats, had delusions, and showed cognitive dysfunctions. The implications of these findings on definition of the organic manic syndrome are discussed.
Insights
Organic manic syndrome cases were identified and compared to bipolar disorder patients. Organic manics showed more irritability, delusions, and cognitive issues, with slower improvement over time.
Area of Science:
- Neuroscience
- Psychiatry
- Clinical Psychology
Background:
- Organic manic syndrome (OMS) is a subtype of mania with neurological or systemic causes.
- Distinguishing OMS from bipolar mania is crucial for accurate diagnosis and treatment.
Purpose of the Study:
- To prospectively identify and characterize cases of organic manic syndrome.
- To compare the clinical presentation and outcomes of OMS with bipolar mania.
Main Methods:
- A prospective study identified 30 cases of OMS over 11 months.
- OMS patients were compared to 60 sex- and age-matched bipolar disorder controls.
- Clinical symptoms, family history, and treatment response were assessed.
Main Results:
- OMS constituted 1.75% of all admissions and 4.67% of mania patients.
- No significant difference in age of onset was observed between groups.
- Organic manics exhibited more irritability, threats, delusions, and cognitive dysfunction.
- Organic manics showed less improvement after 3 months compared to bipolar controls.
- A negative family history of affective disorder was more common in organic manics.
Conclusions:
- Organic manic syndrome presents with distinct clinical features including irritability, delusions, and cognitive deficits.
- Patients with OMS may have a poorer treatment response compared to those with bipolar mania.
- Findings support refining the definition and diagnostic criteria for organic manic syndrome.
