This article describes the development of a prospective, longitudinal study of 88 "high-risk" offspring of pregnant index women with a history of nonorganic psychoses and 104 offspring of demographically-similar pregnant control women. The maternal psychoses represented the diagnostic categories, Schizophrenia, Cycloid Psychosis, Affective Illness, Psychogenic Psychosis, Postpartum Psychosis and Other (remaining) Psychoses. The first phase of the study began during pregnancy and continued until the offspring reached 2 years of age. Selected characteristics of the mothers, the offspring and their environments were investigated during this project phase.

A case of a puerperal psychosis in a 26-year-old woman who had a strong family history of schizophrenia is reported. Her symptoms resolved with chlorpromazine and electroconvulsive therapy, but recurred each month just before the onset of menses. The cyclical recurrence of symptoms was prevented by therapy with danazol, a synthetic steroid which inhibits ovulation and may influence several levels of the reproductive control mechanism from the hypothalamus to the uterus. This therapy may be helpful for other women who suffer from recurrence of severe psychiatric disorders in close association with the menstrual cycle.

Fifty-eight psychoses beginning within two weeks of childbirth are compared with 52 episodes of nonpuerperal psychotic illness occurring in young women. A clinical approach based on the use of multiple information sources and integrated assessment was used. Statistically significant differences between the two groups of patients were found in 52 of 214 psychopathological variables. Postpartum patients had more manic symptoms and "confusion," while nonpuerperal patients had more schizophrenic symptoms. The Research Diagnostic Criteria (RDC) showed an excess of schizoaffective (manic) puerperal patients and schizoaffective (depressed) or schizophrenic nonpuerperal patients. Only five of 58 puerperal episodes met RDC for schizophrenia. The relative lack of schizophrenic symptoms in the puerperal group was confirmed by self-ratings. The results are interpreted as supporting a link between puerperal psychosis and manic-depressive disease.

Among 30 women suffering from a postpartum psychosis without affective syndrome, and for whom this episode of illness was the first leading to psychiatric hospitalisation, 19 fulfilled in the long-term course the DSM-III-R criteria for schizophreniform psychosis (SCHF) or brief reactive psychosis (BRP), and 11 fulfilled the criteria for schizophrenia (SCH). The two groups were compared in order to investigate their nosological relation. Patients with SCHF or BRP more often had the symptomatology of cycloid psychoses and signs of confusion, the onset of illness was more frequently abrupt and the age at the index delivery tended to be lower (p < 0.07) than in patients with SCH. No case of SCHF or BRP was observed at the index episode that later developed into SCH. These findings, together with the different liability to puerperal decompensations, suggest that SCHF and BRP beginning in the postpartum period are nosologically distinct from SCH.

86 cases of narrowly defined postpartum psychosis were investigated with regard to onset and course of symptomatology. The most frequent initial symptoms were restlessness, paranoid symptoms, catatonic excitement, anxiety, sleep disturbances and depressed mood. 16 patients had died at the time of follow-up. Concerning the further course of the disease 64% of the 61 women who were followed up (average 26 years from onset), had recurrences of illness. The most frequent longitudinal diagnosis, in 49% of the 61 cases, was 'schizoaffective disorder'; only 28% of patients were diagnosed as having schizophrenic disorders at follow-up.

In a polydiagnostic study, a systematically recruited collective of 34 women with a first-episode postpartum psychosis was reexamined after a period of 6-26 years (averaging 12.6 years) in order to establish lifetime-diagnoses according to ICD-10 and Leonhard's classification, and to determine course and outcome. According to ICD-10, unipolar depressive disorders (32%) and acute polymorphous psychotic disorders (28%) represented the most frequent diagnoses. Applying Leonhard's classification revealed a marked predominance of cycloid psychoses (62%) with the subform of motility psychosis being the most frequent diagnosis (38%). Schizophrenias occurred rarely according to both classifications. Investigating the long-term course, we found in 59% multiphasic disorders. The mean number of episodes per patient was 2.5 (range 2-6) with a mean duration of 9.8 weeks (SD = 5.2). 6 patients (18%) had undergone a monophasic course, in 4 cases (12%) the course was not determinable. 17 women (50%) had 19 further deliveries during the follow-up period. The frequency of relapses in connection with a further delivery was 47%. Administering the Strauss-Carpenter-Outcome-Scale revealed a favourable outcome with a mean value of 14.1 (SD = 2.83) for our total sample. Only 4 patients (12%) had never recovered fully since the onset of the illness. Our findings suggest that cycloid psychoses, in particular motility psychoses, account for the majority of postpartum psychoses, and do not support the hypothesis of a nosological independence of postpartum psychoses. They provide further evidence of a favourable prognosis of severe postpartum psychiatric disorder despite a relatively high rate of non-puerperal and especially puerperal relapses.

alpha(2) adrenergic receptors are activated by adrenaline and noradrenaline, and three subtypes (ie, A, B, C) have differential affinities for antagonists and medications. The alpha(2c) adrenergic receptor (ADRA2C), located on chromosome 4p16.3, is a candidate gene for schizophrenia because it binds clozapine, an atypical neuroleptic useful for treatment-resistant schizophrenia. In addition, ADRA2C binds clonidine which is prescribed for three psychiatric diseases. This report communicates the findings of the genetic scanning of this gene of very tough GC content. The complete coding sequences and splice junctions were scanned with [DOVAM]-S in 104 schizophrenics, and pilot probes of patients with alcoholism (41 patients), cocaine abuse (25 patients), puerperal psychosis (30 patients), attention deficient/hyperactivity disorder (25 patients) and autism (25 patients). Six sequence variants were found, including five silent polymorphisms (allele frequencies 0.6--25%) and an in-frame deletion of a homologous repeat at nucleotides 967--978 (ie, TIDRU(1)). Genotyping of the normal two repeat unit of the Third Intracytoplasmic Domain Repeat Unit (TIDRU(2)) and the deleted variant (TIDRU(1)) revealed that TIDRU(1) had allelic frequencies of 39% (11/28) and 3.5% (6/172) in African-American and Caucasian schizophrenics, respectively, and it occurred with equal frequency in controls (44%, 31/70 and 3.0%, 6/198). TIDRU(1) occurs at a location similar to the third intracytoplasmic 48-nucleotide repeat unit in the DRD4 that is associated with ADHD. Although these data do not suggest an association of TIDRU(1) with schizophrenia, additional studies are needed to see whether TIDRU(1) confers a clinical phenotype.

Estrogen and thyroid hormones exert effects on growth, development, and differentiation of the nervous system. Hormone administration can lead to changes in behavior, suggesting that genetic variants of the estrogen receptor alpha (ERalpha) and the thyroid hormone receptor alpha (TRalpha) genes may predispose to psychiatric diseases. To investigate this possibility, regions of likely functional significance (all coding exons and flanking splice junctions) of the ERalpha and TRalpha genes were scanned in patients with schizophrenia (113), along with pilot studies in patients with bipolar illness (BPI), puerperal psychosis, autism, attention-deficit hyperactivity disorder (ADHD), and alcoholism. A total of 1.18 megabases of the ERalpha gene and 1.16 megabases of the TRalpha gene were scanned with Detection of Virtually All Mutations-SSCP (DOVAM-S), a method that detects virtually all mutations. Four missense mutations, seven silent mutations and one deletion were identified in the ERalpha gene, while only four silent mutations were present in the TRalpha gene. Two of the missense mutations in ERalpha are conserved in the six available mammalian and bird species (H6Y, K299R) and a third sequence variant (P146Q) is conserved in mammals, birds, and Xenopus laevis, hinting that these sequence changes will be of functional significance. These changes were found in one patient each with BPI, puerperal psychosis, and alcoholism, respectively. Analysis of the ERalpha and TRalpha genes in 240 subjects reveals that missense changes and splice site variants are uncommon (1.7% and 0%, respectively). Further analyses are necessary to determine if the missense mutations identified in this study are associated with predisposition or outcome for either psychiatric or nonpsychiatric diseases.

The glycine receptor, which is a member of the ligand-gated ion channel superfamily, mediates synaptic inhibition in the spinal cord and other brain regions. This superfamily has been implicated in the pathogenesis of schizophrenia and other psychiatric diseases. The complete coding sequence and splice junctions of the GLRA2 gene were scanned by DOVAM-S, a form of SSCP analysis with sufficient redundancy to detect virtually all mutations. Those analyses were performed in 113 patients with schizophrenia, and in pilot studies of patients with bipolar illness, alcoholism, puerperal psychosis, autism, and attention-deficit hyperactivity disorder (533 kb total scanned sequences). We detected three sequence changes in the coding region, all resulting in silent mutations: C894T in exon 5, C1134T in exon 7, and C1476T in exon 9. These do not alter the structure or the expression of the protein. It is unlikely that mutations in the coding region and splice junction of GLRA2 gene are associated with schizophrenia and other psychiatric diseases.

Eighty six in-patients suffering from puerperal psychosis within six weeks after childbirth were prospectively investigated in Muhimbili National Hospital during two years. Formal psychiatric history, mental status evaluation, research and diagnostic criteria including ICD 10 and clinical progression were employed for diagnosis. Using a structured questionnaire, the socio-demographic characteristics, concomitant physical disorders, major obstetric events, period of onset of puerperal psychosis following delivery and social support given were established. Mean age was found to be 23.6 years; the majority was primiparous women with parity of between one and three children. Main physical co-morbidities included anaemia in 51.4% of cases, infections in 44.2% and EPH-gestosis in 17.4%. Most mothers received social support from their extended families. Organic psychosis was found in four fifths of the mothers and schizophrenia in 8.1%. A high rate of early onset puerperal psychosis (3.2/1000 (births), predominantly in young primiparous women, was found.
