A study of 204,186 people across 46 low- and middle-income countries found that low physical activity is associated with a diagnosis of psychosis, particularly among males. However, psychotic-like symptoms without a diagnosis are not linked to inactivity.
A study found that individuals with smaller hippocampi are more likely to have a combination of genetic risk factors associated with an increased risk of psychosis. This discovery may lead to the development of personalized treatment strategies for schizophrenia.
A systematic review of 35 studies found that longer duration of untreated childhood schizophrenia-spectrum psychosis is associated with poorer functional improvement. Children and adolescents with EOS often experience frequent pre- and co-morbid conditions, leading to worse outcomes.
A new clinical calculator assesses individual risk of psychosis after early warning signs of schizophrenia, such as hearing voices. Symptoms like unusual thought content and social functioning decline contribute significantly to the risk of developing psychosis.

Researchers have found a link between the AKT1 gene and psychotic-like symptoms in young people who use cannabis. The study suggests that individuals with this gene variant are more susceptible to the mind-altering effects of smoking cannabis, even if they are otherwise healthy.
A professor of psychiatry argues that schizophrenia should be replaced with 'psychosis spectrum syndrome' due to the complexity and heterogeneity of psychotic illness. The current classification system uses outdated language and may lead to misdiagnosis or overemphasis on this condition.
A new analysis shows that team-based coordinated specialty care (CSC) is more cost-effective than typical community care for young people with first episode psychosis. CSC produces better clinical and quality of life outcomes, making it a better value despite modestly higher costs.

Researchers found that people with Alzheimer's who had more physical signs of the disease were also more likely to have psychosis. However, when they looked at those whose autopsies confirmed Alzheimer's, psychosis did not correlate with physical evidence of the disease. Instead, it was linked to vascular risk factors and cerebral inju...
A team of researchers has identified biological markers that can classify mental disorders with greater precision, using neurobiological measures to differentiate conditions. The findings may lead to improved diagnostics and treatments for those suffering from mental illness.
A UTSW-led study identified three neurobiologically distinct biotypes of psychoses, which do not always match conventional clinical diagnoses. The findings suggest that the term 'psychosis' might describe unique psychiatric disorders with distinctive mechanisms and treatments.
A new study finds that biomarkers outperform symptoms in identifying distinct psychosis subgroups, suggesting a more precise diagnosis may lead to improved treatments. The research used 1,872 participants and identified three biotypes, each with unique patterns of brain function and structure.
A team-based, coordinated specialty care approach produces better clinical and functional outcomes than typical community care for people with first episode psychosis. Treatment is most effective when provided soon after psychotic symptoms begin.
Researchers found that individuals with early signs of psychosis relied more heavily on prior knowledge to interpret ambiguous images, leading to improved task performance. This suggests an altered balance in normal brain functions contributing to the emergence of mental illness symptoms.
A new analysis identified illogical thoughts as most predictive of schizophrenia risk in teens experiencing attenuated psychosis symptoms. Suspiciousness and unusual thought content were found to be the most informative symptoms, while perceptual disturbances - common features of schizophrenia - were not predictive.
A new study found that people with Parkinson's disease psychosis who took antipsychotic medication were four times more likely to die than those who didn't. The treatment also led to serious health issues such as cognitive decline and worsening of Parkinson's symptoms.
A study by Columbia University's Mailman School of Public Health found that young people identified as 'at risk' for mental problems described feeling stigmatized by symptoms, but not the label itself. Early intervention benefits may outweigh stigma concerns.

Researchers detected antibodies to dopamine D2 receptor and N-methyl-D-aspartate (NMDA) glutamate receptor among children experiencing their first episode of psychosis. The finding suggests a distinct subgroup where autoimmunity plays a role in their illness, paving the way for more specific diagnosis and effective interventions.
A new study has identified antibodies targeting dopamine D2 receptors and NMDA glutamate receptors in children experiencing their first episode of psychosis. This finding suggests that autoimmunity may play a role in the development of psychosis, offering hope for new treatment approaches.
A recent study found that adolescents with psychological symptoms often exhibit visual distortions and hallucinations before developing a full-blown mental disorder. The researchers also discovered that these symptoms are strongly linked to self-destructive thought processes, which can increase the risk of suicide.
A new study finds that gray matter loss in the brain is a precursor to psychosis, with increased inflammation accelerating this process. Researchers analyzed brain scans of young adults at clinical high risk for psychosis and healthy controls, revealing a significant correlation between proinflammatory cytokines and gray matter thinning.
Almost 40% of people with first-episode psychosis in community clinics may benefit from medication treatment changes. Current prescribing practices highlight the need for more education on first-episode specific medication practices at community facilities.

The study found that individuals at clinical high risk for psychosis who developed a psychotic disorder had reduced mismatch negativity compared to those who did not.
Researchers at Penn Medicine developed a method to assess and diagnose psychosis in young children by analyzing cognitive development. The study found that children with psychotic symptoms had lower chronological ages than predicted, indicating a significant lag in cognitive development.
Research finds a link between childhood death of a nuclear family member and increased risk of psychosis. Exposure to suicide has the highest risk, especially in early childhood.

The study found that the algorithm was able to differentiate between patients who would develop continuous psychosis and those with more benign forms in seven out of ten cases.
A meta-analysis of 83 studies suggests that cannabis users develop psychosis about 2.7 years younger than non-users. The study supports the view that cannabis precipitates schizophrenia and other psychotic disorders, potentially through genetic and environmental interactions or disrupting brain development.

A study of 3,801 young adults found that those who used cannabis for six or more years were twice as likely to develop non-affective psychosis. The longer duration since first cannabis use was associated with higher risk of psychosis-related outcomes.
A 12-week fish oil capsule course reduced psychotic disorder progression by 22.6% in high-risk individuals, with improved symptoms and functioning compared to placebo. Omega-3 fatty acids may offer a safe prevention strategy for young people at risk of psychosis.
A new UK study found that heavy cannabis use is associated with a higher risk of developing schizophrenia in young people. To prevent one case of schizophrenia, it would be necessary to stop around 2,800 male and 5,000 female heavy users, or over 10,000 and 30,000 light users, respectively.
A study by psychiatrist Szabolcs Kéri found a clear link between neuregulin 1 gene variant and increased creativity. Volunteers with the specific variant scored higher on creativity assessments and reported greater lifetime creative achievements.
