SummaryA group of 46 bipolar probands and their first degree relatives were studied. A high rate of affective disorder (19.6 per cent) was found, including both unipolar (13.2 per cent) and bipolar (6.4 per cent) types, with females predominating (3: 1). The presence of four father-son pairs suffering from affective disorder made the hypothesis of X-linked dominance untenable. Results compatible with polygenic inheritance were found, using both Slater's and Falconer's methods. There was no evidence for assortative mating or for increased total number of females (both well and ill) among first degree relatives. The probands and affectively ill first degree relatives who have died show an alarmingly high rate of suicide (46 per cent). Other forms of mental disorder, including alcoholism, were no more common than in the rest of the community.

Abstract Background Bipolar disorder is one of the world’s 10 most disabling conditions, taking away years of healthy functioning from individuals, all bipolar disorders are chronically recurring illnesses associated with substantial morbidity and mortality. Impulsivity considered an integral part of bipolar disorder. Operationalized as a predisposition to action without reflection or regard for consequences. Potential consequences of this increased impulsivity include substance abuse, suicidal attempts, and other serious behavioral problems. Aim of the Study The aim of the current study was to measure impulsivity in both BD euthymic patients and in healthy first-degree relatives of BD patients. And to assess the functional implications of impulsiveness, on psychosocial functioning and in bipolar disorder patients, their first-degree relatives. Patients and Methods A convenient sample of 50 patients; diagnosed with bipolar affective disorder according to DSM-IV diagnostic criteria were selected from the general adult psychiatry clinics and a convenient sample of 50 healthy first degree relatives of BD patients. Results We concluded by the end of this study that both cases and relatives have high overall impulsivity, and cases have higher impulsivity in comparison to relatives. Conclusion We suggest that impulsivity may be a potentially valuable candidate endophenotype for bipolar disorder.

However Ohara reported that 10% of pregnant women was eligible if diagnosed with major and minor depression. There are two phases of pharma- cological management is described in the guidelines panel: the acute phase, symptoms are treated, drug dosage adjusted to prevent the adverse effects and patient given counseling, severe phase, patients were monitored at an effective dose to prevent relapse . In the maintenance phase, patients at risk for relapse is often still treated with medicines. Reported here the case of a female patient aged 31 years diagnosed with G2P1A0H1 term gravid 37- 38 weeks + bipolar affective disorder, current episode manic with psychotic symptoms. Patients have been known to suffer from a mental disorder since 2000 and has been submitted to psychiatry ward for as much as 9 times. Trigger disorder is unknown at this time, the patient suddenly angry for no apparent reason. Patients treated with pharmacotherapy of haloperidol 2x2 mg, roboransia and psychotherapy. Treatments including consideration of the patient to provide pharmacological therapy in a minimun dosage and psychotherapy to effectively reduce teratogenic risk to the fetus.
