OBJECTIVE Despite clear gender differences in the symptoms and course of bipolar affective disorder, studies investigating age at onset by gender have yielded inconsistent results. The authors investigated gender differences in age at onset and incidence of first-episode mania and bipolar disorder in an epidemiological catchment area in southeast London over a 35-year period. METHOD All adult cases of first-episode psychosis, mania, or hypomania presenting to services in Camberwell, southeast… 

Figures and Tables from this paper

Age of onset and the prospectively observed course of illness in bipolar disorder.
Early age at onset of bipolar disorder is associated with more severe clinical features but delayed treatment seeking.
TLDR
Although BD patients with early age at onset have more severe clinical features and illness course, the delays from first episode to treatment and to correct diagnosis are longer than for those with adult onset disorder.
Risks associated with gender differences in bipolar I disorder.
Evidence that bipolar disorder is the poor outcome fraction of a common developmental phenotype: an 8-year cohort study in young people
TLDR
This study showed, for the first time, that experiencing (hypo)manic symptoms is a common adolescent phenomenon that infrequently predicts mental health care use and suggests that the onset of bipolar disorder can be elucidated by studying the pathway from non-pathological behavioural expression to dysfunction and need for care.
Differences between prepubertal- versus adolescent- onset bipolar disorder in a Spanish clinical sample
ObjectiveTo examine patients attended and diagnosed with bipolar disorder (BD) at a child and adolescent psychiatry service; to record age of diagnosis and age of onset, and to study clinical
Sex Differences in the Longitudinal Course and Outcome of Bipolar Disorder in Youth.
TLDR
Controlling with adult literature, this study identified minimal sex differences in the course of youth with bipolar disorder or operationalized BD or diverges according to sex in adulthood.
Gender difference in age at onset of schizophrenia: a meta-analysis
TLDR
The gender difference in age of onset in schizophrenia is smaller than previously thought, and appears absent in studies using ICD, while there is no evidence that the gender difference differs between developed and developing countries.

TLDR
The results suggest that schizophrenia syndrome is heterogeneous, and young males are especially prone to a severe neurodevelopmental form of illness associated with premorbid deficits.

TLDR
A review of the literature concerning gender differences in age at the onset of schizophrenia looked for evidence for the existence of local or temporal variations in the degree of gender difference by means of a metaanalytic approach.

TLDR
Women were diagnosed as bipolar later than men with corresponding delay of lithium maintenance treatment that proved to be at least as effective as in men, and showed non-significantly superior responses to lithium treatment.
