Study Finds Sharp Rise in Depression and Psychosis Risk After Childbirth
Women face a significantly higher risk of developing serious mental health conditions in the weeks following childbirth, according to a major new study published in Molecular Psychiatry. The research highlights the critical importance of monitoring maternal mental health in the postpartum period.
The study, which examined data from nearly 1.8 million births in Sweden between 2003 and 2019, found that the risk of depression rises by about 20 percent in the five to 15 weeks after childbirth compared to the year before pregnancy. Even more striking, the risk of psychosis is six to seven times higher in the first five weeks postpartum and remains double the pre-pregnancy level through week 20.
Researchers stressed that postpartum psychosis, unlike the temporary “baby blues” many women experience, is a severe mental health condition requiring urgent treatment. Symptoms can include delusions, hallucinations, mania, low mood, and confusion. However, with proper medical care, recovery is possible. “The drastic peak observed postpartum clearly highlights the vulnerability of new mothers,” the authors wrote.
The analysis also showed that diagnoses of depression and psychosis rise most sharply after delivery, while conditions such as anxiety, stress-related disorders, and substance abuse decline during and after pregnancy. Researchers suggested this trend may reflect biological and lifestyle changes, as well as closer medical supervision during pregnancy.
Women typically have more frequent contact with healthcare providers while pregnant, which can lead to earlier detection and intervention. “We don’t see that more people are being diagnosed, but screening could mean that women are identified earlier and don’t have to suffer as long before they can get the support and help they need,” said Emma Bränn, a researcher at Sweden’s Karolinska Institutet and one of the study’s authors.
Globally, the World Health Organization estimates that around 10 percent of pregnant women and 13 percent of women after childbirth suffer from a mental disorder, most often depression. The Swedish findings add to growing evidence that the postpartum period is a time of heightened vulnerability, particularly for severe conditions like psychosis.
Despite these risks, another recent study from the Karolinska Institutet found that suicide attempts among new parents in Sweden decline in the weeks after childbirth. Mothers, in particular, were less likely to attempt suicide during or after pregnancy compared to fathers—a finding that stands in contrast to broader population trends, where women are more likely than men to attempt suicide.
Experts say the research underscores the need for targeted mental health support for women after childbirth. While pregnancy itself may provide some protective factors, the weeks following delivery remain a period of elevated risk requiring careful attention from families, healthcare systems, and policymakers.

Global Mental Health Cases Near 1.2 Billion as Anxiety and Depression Drive Sharp Worldwide Rise
A major global analysis has found that mental health conditions have surged to an estimated 1.2 billion people worldwide, driven largely by steep increases in anxiety and depression over the past three decades.
The findings, published in The Lancet as part of the Global Burden of Disease Study 2023, show that the number of people living with mental disorders has almost doubled since 1990, marking a 95% rise. Researchers say major depressive disorder and anxiety disorders have seen even sharper growth, increasing by 131% and 158% respectively, making them the most prevalent mental health conditions globally.
The report describes mental illnesses as widespread conditions that create long-term disability and significant human suffering. It also highlights broader consequences for economies and public services, including reduced productivity, lower workforce participation and increasing pressure on health and welfare systems.
Researchers estimate that in 2023 alone, around 620 million females and 552 million males were affected by mental health conditions. While the overall burden is rising across both sexes, the study points to notable differences in the types and prevalence of disorders.
Among women, depression and anxiety were the most commonly reported conditions, alongside higher rates of eating disorders such as anorexia nervosa and bulimia nervosa. The report links this disparity to a mix of biological, social and structural factors, including exposure to domestic violence, sexual abuse, gender inequality and reproductive health-related changes.
In contrast, neurodevelopmental and behavioural disorders, including attention deficit hyperactivity disorder (ADHD), conduct disorder and autism spectrum conditions, were more frequently diagnosed in men.
Teenagers aged 15 to 19 were identified as the group experiencing the highest mental health burden globally, raising concerns about early onset of conditions and insufficient preventive care for young people.
The study identifies several key risk factors associated with mental illness, including childhood sexual violence, bullying and intimate partner violence. These factors are strongly linked to conditions such as depression, schizophrenia, bipolar disorder and anxiety disorders. However, researchers note that such exposures have remained relatively stable over time and account for only a portion of the overall rise.
According to the authors, broader drivers are likely contributing to the increasing prevalence of mental disorders. These include genetic and biological influences, poverty, inequality, and the growing impact of global crises such as armed conflict, pandemics, natural disasters and climate-related stress.
While mental health conditions have long been a leading cause of disability worldwide, the report warns that the situation is worsening. At the same time, health systems have not expanded services at a pace matching demand.
The authors caution that the gap between rising need and limited access to care is becoming more pronounced, leaving millions without adequate treatment or support.
