“…There were more males in the MO . This is in keeping with earlier studies showing that unipolar mania appears to be more common in men 11,19 while some showed no statistical difference [16][17][18] and in one study there were more females compared to males with unipolar mania but not statistically significant 21 …”

“…Some researchers have observed characteristics specific to patients with unipolar mania as opposed to bipolar disorder. Unipolar mania appears to be more common in men 11,19 and had an earlier age at onset of illness 9,22 . In the present study (as depicted in Table 5) the following differences appeared when comparing the Depressive and manic (DAM) group with the Manic only (MO) group.…”

Objective: There is a lack of studies that examine prevalence and phenomenology of bipolar disorder in Africa. In literature, a unipolar manic course of illness in particular is reported to be rare. The purpose of this study was to investigate and describe the course of illness and clinical features for a cross-section of patients diagnosed with bipolar disorder attending public hospitals in Limpopo Province, South Africa and to determine the rate of a unipolar manic course in this sample of patients. Method: This was a descriptive, cross-sectional study of patients presenting with a history of mania between October 2009 and April 2010, to three hospitals in Limpopo Province. A purposeful sample of 103 patients was recruited and interviewed using the Affective Disorders Evaluation. Results: This study confirms that a unipolar manic course is indeed much more common than occurrences suggested in present day literature, with 57% of the study sample ever experiencing manic episodes. Patients presenting with a unipolar manic course of illness, as described in this study, may contribute to the search for an etiologically homogeneous sub-group, which presents a unique phenotype for genetic research and the search for genetic markers in mental illness. With a view to future research, a unipolar manic course therefore needs to be considered as a specifier in diagnostic systems in order to increase the awareness of such a course of illness in bipolar disorder. Conclusion: Fifty seven percent (57%) of study subjects had only ever experienced manic episodes, which is in keeping with findings from Africa and other non-Western countries. Identifying etiologically homogenous subgroups in psychiatry can also aid the profession in developing a reliable and valid nosology for psychiatric disorders. We need to consider a unipolar manic course at least a specifier in DSM and ICD.

“…A few cases of depression with atypical manifestation may not be recognized early in this society, however, which is similar to what obtains in other cultures. The rate of recurrent unipolar mania in this study is remarkably higher than that found in Massachusetts, USA, in an elderly cohort (12%) [14] and that in another study conducted in New York state, USA (18%) [10]. It is, however, lower than that reported in a similar study conducted in Nigeria, although unlike the present study, that study was a prospective one [12].…”

“…However, a higher mean age of onset for unipolar mania was found by Abrams et al [10]. In their study, unlike the present one, cases of first-episode mania were included in the unipolar mania sample.…”

“…In recent times, there have been a number of studies aimed at establishing the true position of unipolar mania. Some studies supported the recognition of unipolar mania as a separate entity and thus challenged its present status [10][11][12][13][14]. Others did not uncover enough evidence to justify any modification to its current position within bipolar affective disorder [15][16][17].…”

This study aimed to determine the rate of unipolar mania and compare its characteristics with those of other bipolar affective disorders in a psychiatric hospital in the Fiji Islands. Fifty-one patients with unipolar mania seen between January 1999 and October 2000, had their diagnosis confirmed using the Schedules for Clinical Assessment in Neuropsychiatry and the International Classification of Diseases, 10th edition. Their demographic and clinical characteristics were compared with those of 31 manic-depressive patients seen during the period under review. Unipolar mania constituted 47.2% of the bipolar affective disorders in this sample. The frequency of episodes, duration of affective illness, mean age at onset, gender distribution, marital status, employment status and race were not significantly different for the unipolar manic and manic-depressive groups (p > 0.05). Family history of major psychiatric morbidity was 9.8% for the unipolar manic patients and 22.6% for the manic-depressive group (p > 0.05). Recurrent unipolar mania may be considered a useful category based on its high rate, although its demographic and clinical characteristics do not clearly distinguish it from manic-depression.
