Postpartum psychiatric disorders

This review summarises the psychiatry of the puerperium, in the light of publications during the past 5 years. A wide variety of disorders are seen. Recognition of disorders of the mother-infant relationship is important, because these have pernicious long-term effects but generally respond to treatment. Psychoses complicate about one in 1000 deliveries. The most common is related to manic depression, in which neuroleptic drugs should be used with caution. Post-traumatic stress disorder, obsessions of child harm, and a range of anxiety disorders all require specific psychological treatments. Postpartum depression necessitates thorough exploration. Cessation of breastfeeding is not necessary, because most antidepressant drugs seem not to affect the infant. Controlled trials have shown the benefit of involving the childs father in therapy and of interventions promoting interaction between mother and infant. Owing to its complexity, multidisciplinary specialist teams have an important place in postpartum psychiatry.

Anxiety, obsessions and morbid preoccupations in pregnancy and the puerperium

Summary129 mothers referred to specialist psychiatric services in Birmingham and Christchurch were interviewed with the Birmingham Interview. Anxiety disorders were more frequent than depression during pregnancy, and equally frequent after delivery. The focus of pre- and post-partum anxiety may be important for psychological treatment. At a severe level, the most common prepartum theme was fear of foetal death; this was associated with a history of reproductive losses or infertility. After delivery the commonest themes were the pathological fear of cot death and fear of the criticism of mothering skills (which was a clue to a disordered mother-infant relationship). Clinicians should be vigilant for obsessional disorders, querulant (complaining) disorders, post-traumatic stress disorder, conjugal jealousy and dysmorphophobic states, which are all quite common. Patients with “postpartum depression” usually had at least one other (co-morbid) disorder, and 27% had two or more. These findings emphasize the diversity of postpartum psychiatric illness.

WPA guidance on the protection and promotion of mental health in children of persons with severe mental disorders

This guidance details the needs of children, and the qualities of parenting that meet those needs. Parental mental disorders can damage the foetus during pregnancy through the action of drugs, prescribed or abused. Pregnancy and the puerperium can exacerbate or initiate mental illness in susceptible women. After their birth, the children may suffer from the social disadvantage associated with severe mental illness. The parents (depending on the disorder, its severity and its persistence) may have intermittent or prolonged difficulties with parenting, which may sometimes result in childhood psychological disturbance or child maltreatment. This guidance considers ways of preventing, minimizing and remedying these effects. Our recommendations include: education of psychiatrists and related professions about the effect of parental mental illness on children; revision of psychiatric training to increase awareness of patients as caregivers, and to incorporate relevant assessment and intervention into their treatment and rehabilitation; the optimum use of pharmacological treatment during pregnancy; pre-birth planning when women with severe mental illness become pregnant; development of specialist services for pregnant and puerperal women, with assessment of their efficacy; community support for parenting by mothers and fathers with severe mental disorders; standards of good practice for the management of child maltreatment when parents suffer from mental illness; the importance of multi-disciplinary teamwork when helping these families, supporting their children and ensuring child protection; the development of child and adolescent mental health services worldwide.

Molecular genetic studies of bipolar disorder and puerperal psychosis at two polymorphisms in the estrogen receptor alpha gene (ESR 1)

A number of lines of evidence point to the possible involvement of estrogen pathways in the pathophysiology of bipolar disorder in general and puerperal psychosis in particular. There is strong evidence from clinical, follow-up, and genetic studies to support the hypothesis that most cases of puerperal psychosis are manifestations of an affective disorder diathesis with a puerperal trigger and that genes influence susceptibility to both diathesis and trigger. The nature of the trigger is unknown but in view of the abrupt onset at a time of major physiological change it is widely believed that biological, probably hormonal, mechanisms are of paramount importance, with estrogen receiving the most attention to date. We have undertaken a case control association study of bipolar disorder and puerperal psychosis at two known polymorphisms within the estrogen receptor alpha gene (ESR 1) in a sample of 219 unrelated bipolar probands and 219 controls. We could exclude these polymorphisms from an important contribution to susceptibility to bipolar disorder with a high level of confidence. We found no support for the hypothesis that they contribute specific susceptibility to the puerperal trigger, but due to the small numbers of puerperal probands (n = 26) no firm conclusions can be drawn regarding their involvement in puerperal psychosis.

Molecular genetic approaches to puerperal psychosis

Puerperal psychosis, an episode of mania or psychosis precipitated by childbirth follows approximately one in 1000 deliveries. The evidence of clinical, outcome and genetic studies supports the hypothesis that the majority of puerperal psychotic episodes are manifestations of an affective disorder diathesis with a puerperal trigger. Furthermore the available evidence supports the hypothesis that genes are involved in susceptibility to both diathesis and trigger. For complex genetic disorders such as affective illness there are marked benefits in focussing on a homogeneous subtype which allows a subset of hypotheses to be tested. Molecular genetic studies of puerperal psychosis provide an excellent example of this strategy, allowing a hierarchy of hypotheses concerning the involvement of neurosteroid pathways in pathophysiology to be tested. Puerperal psychosis results in considerable suffering to a woman and her family. Elucidating the pathophysiological basis of this disorder will lead to better prevention and treatment and, it is anticipated, inform research on affective disorders more generally.

Urinary dimethyltryptamine and psychiatric symptomatology and classification.

The excretion of dimethyltryptamine (DMT) was studied amongst 122 recently admitted psychiatric patients and 20 normal subjects. DMT was detected in the urine of 47% of those diagnosed by their psychiatrists as schizophrenic, 38% of those with other non-affective psychoses, 13% of those with affective psychoses, 19% of those with neurotic and personality disorders and 5% of normal subjects. Ninety-nine patients were interviewed in a semi-standardized fashion, and also categorized according to a variety of operational definitions of the psychoses. The operational definitions failed to reveal any group significantly more correlated with urinary DMT than a hospital diagnosis of schizophrenia, but a discriminant function analysis of symptomatology could be used to define a group of 21 patients of whom 15 (71%) excreted detectable DMT. There was a general relationship between psychotic symptoms and urinary DMT, but specifically schizophrenic symptoms did not appear to be major determinants of DMT excretion.

Maternal Rejection of the Young Child: Present Status of the Clinical Syndrome

This article reviews severe disorders of the mother-infant relationship involving emotional rejection of the infant in the first year of its life. Infants exposed to their mother’s hatred and rage may suffer far-ranging and long-term disadvantages, and are at risk of maltreatment. Diagnosis, therapy and research have been hampered by the lack of recognition of this clinical syndrome in the classifications. The imminent revision of these classificatory systems must include them.

Clinical clues to the aetiology of puerperal psychosis

Recent case reports of postpartum psychosis are reviewed, which suggest hypotheses for the aetiology of this disease. The main themes are: The relationship to manic depression. Premenstrual relapse. Prepartum onset. Onset after miscarriage or evacuation of a trophoblastic tumour. Onset after bromocriptine treatment. Attempts to treat this and related psychoses by progesterone. Apomorphine growth hormone challenge tests.

Delusional Denial of Pregnancy as a Special Form of Cotard’s Syndrome

The following case report describes a pregnant woman who was convinced that her pregnancy was non-existent despite being in an advanced stage of clinically obvious pregnancy. The nosologically unspecific syndrome of denial of pregnancy is discussed by reviewing the literature. Based on the existing literature it will be explained why this specific syndrome is considered to indicate a special form of Cotard’s syndrome.

Menstrual psychosis: a bipolar disorder with a link to the hypothalamus.

The literature on menstrual psychosis is briefly reviewed in this article. There are about 80 cases with substantial evidence, and about 200 other possible cases. The clinical features are generally those of manic depressive (bipolar) disorder. The diagnosis requires the accurate dating of the onsets of episodes and of menstrual bleeding. Obtaining a baseline of several carefully dated episodes is also important in finding the best way to arrest the periodic illness. Although conventional psychotropic drugs can shorten episodes, they do not prevent recurrences. For this, unconventional treatments appear to be more effective, especially thyroid hormone and clomiphene. Patients with menstrual psychosis usually have abnormal menstruation, such as anovulatory cycles, luteal defects, or periods of amenorrhea. This, and the occurrence of episodes before the menarche, suggests that the interaction between the bipolar diathesis and menstruation is in the hypothalamus.
