Follow-up and family study of postpartum psychoses. Part IV: Schizophreniform psychoses and brief reactive psychoses: lack of nosological relation to schizophrenia

Mothers with acute and chronic postpartum psychoses and impact on the mother-infant interaction

BACKGROUND

Maternal postpartum psychoses pose a serious risk to the mother-infant interaction. It is unclear how different subtypes of postpartum psychosis, including acute and chronic, might differentially affect the mother-infant interaction.

METHOD

A systematic search of electronic journal databases was performed.

RESULTS

This systematic review yielded 17 studies with adequate overall study quality. They focused on child custody and involvement of social services as indirect indicators of the mother-infant interaction, observed mother-infant interactions as direct indicators, or potential transitional mechanisms, including memory processing, mind-mindedness, and affect recognition, that may partially explain the effects of psychotic disorders. An acute onset of psychosis during the postpartum period (de novo or relapse) was typically related to better mother-infant interactions. Mothers with schizophrenia have the highest risk of child displacement, and interventions by social services were more likely. However, mothers with postpartum schizophrenia did not exhibit more harm to the child or self-harm than mothers with postpartum depression. Heterogeneity of methodology, case definitions, and assessments characterized the studies; hence, they were not pooled.

CONCLUSIONS

In addition to evaluating social risk factors in patients with acute onset and chronic psychoses during the postpartum period, negative preconceptions about motherhood and schizophrenia have to be carefully examined. Clinical research on postpartum psychoses should consider the onset criteria, prevalence of self-harm or harm to the child, significance of specific (e.g., religious) delusions and expressed hostility toward the child. More studies on the impact of first-onset (de novo) postpartum psychoses on the mother-infant interaction are needed.

Case study of first episode schizophrenia in pregnancy and postpartum

Patients with first-episode psychosis of peripartum onset commonly prove to have a mood-disorder diathesis; however, a proportion of cases represent first-episode schizophrenia. We present such a case and discuss the clinical relevance of recognizing this small but important population of new mothers. These patients are at considerable risk of misdiagnosis, resulting in ineffective maintenance therapy, poorer recovery of function, and development of treatment resistance. Accurate diagnosis in the peripartum period will impact treatment decisions and long-term therapy. Clinicians need to be vigilant, especially during maintenance therapy, to identify these patients and ensure appropriate antipsychotic therapy is provided.

A review of postpartum psychosis

OBJECTIVE

The objective is to provide an overview of the clinical features, prognosis, differential diagnosis, evaluation, and treatment of postpartum psychosis.

METHODS

The authors searched Medline (1966-2005), PsycInfo (1974-2005), Toxnet, and PubMed databases using the key words postpartum psychosis, depression, bipolar disorder, schizophrenia, organic psychosis, pharmacotherapy, psychotherapy, and electroconvulsive therapy. A clinical case is used to facilitate the discussion.

RESULTS

The onset of puerperal psychosis occurs in the first 1-4 weeks after childbirth. The data suggest that postpartum psychosis is an overt presentation of bipolar disorder that is timed to coincide with tremendous hormonal shifts after delivery. The patient develops frank psychosis, cognitive impairment, and grossly disorganized behavior that represent a complete change from previous functioning. These perturbations, in combination with lapsed insight into her illness and symptoms, can lead to devastating consequences in which the safety and well-being of the affected mother and her offspring are jeopardized. Therefore, careful and repeated assessment of the mothers' symptoms, safety, and functional capacity is imperative. Treatment is dictated by the underlying diagnosis, bipolar disorder, and guided by the symptom acuity, patient's response to past treatments, drug tolerability, and breastfeeding preference. The somatic therapies include antimanic agents, atypical antipsychotic medications, and ECT. Estrogen prophylaxis remains purely investigational.

CONCLUSIONS

The rapid and accurate diagnosis of postpartum psychosis is essential to expedite appropriate treatment and to allow for quick, full recovery, prevention of future episodes, and reduction of risk to the mother and her children and family.

Follow-up and family study of postpartum psychoses. Part I: Overview

A group of 119 patients suffering from a severe psychiatric postpartum disorder who were admitted for the first time in their life to a psychiatric hospital has been investigated. The onset of illness occurred within 3 months following delivery. The patients represented 92% of the total sample fulfilling the inclusion criteria. A follow-up investigation was performed after a mean of 21 years (range 2-35 years). Of the patients 66% had nonpuerperal psychotic episodes in later life. The diagnosis, taking into account the long-term course, was affective psychosis in 57%, schizoaffective psychosis in 18%, schizophreniform psychosis in 12%, brief reactive psychosis in 4% and schizophrenia in 9%. A bipolar psychosis was found in 31%. The relation of unipolar to bipolar psychoses corresponded to that in a control group of affectively ill women without puerperal onset. The frequency of a manic syndrome in bipolar psychoses at the index episode was the same as in nonpuerperal episodes, which does not suggest a mania-provoking pathoplastic effect of the puerperium. The comparison with female nonpuerperal controls matched for age and diagnosis revealed evidence of a better long-term course in the index patients. The risk of a puerperal relapse for further pregnancies was 35%. The global morbidity risk for functional psychoses in first-degree relatives was 11%, with affective psychoses representing the majority of secondary cases (6.8%). The index patients showed a nonsignificant lower morbidity risk in relatives than a control group of psychotically ill women without puerperal onset. The major aetiological factor found for postpartum psychoses is the relation of these disorders to functional psychoses. There is strong evidence that the postpartum period tends to provoke affective psychoses and other nonschizophrenic psychoses, but not, or only to a lesser degree, narrowly defined schizophrenias. The liability to puerperal decompensations suggests some common pathophysiological mechanism, the nature of which remains unknown.
