A UK-based research team found that prolonged antidepressant use is associated with a sustained increase in weight gain over at least five years. The study analyzed data from over 300,000 adults and showed that patients prescribed any of the 12 most commonly used antidepressants were more likely to experience weight gain.

A nationwide register-based cohort study in Denmark found that children born to mothers taking antidepressants during pregnancy were at increased risk of developing psychiatric disorders. The study suggests that medication alone may not be the sole cause, as heritability also plays a part in determining mental health later in life.
A study by Indiana University found that ICU survivors are at risk for depression, with young and African American survivors being the highest risk. The research emphasizes the need for better mental health care and suggests new approaches to treatment and antidepressant regimens.
A study published in The BMJ found an association between antidepressant use during pregnancy and a higher risk of psychiatric disorder diagnosis in children. Researchers stress that this finding should be interpreted with caution, as the underlying maternal illness may contribute to the increased risk.
A long-term study on schizophrenia patients found that low cumulative exposure to benzodiazepine and antidepressant medications has no significant effect on cognition. However, high-dose use of antipsychotic drugs was associated with poorer cognitive functioning, while a break in treatment was linked to better outcomes.
Researchers found that an antidepressant drug, nortriptyline, slowed the growth of abnormal proteins associated with Parkinson's disease. The study suggests a potential new approach to treating the disease, which could be simpler and more effective than current therapies.
A recent study found that almost all antidepressants present significant side effects, but some individuals may better tolerate certain side effects. Personalized medicine is recommended to match chronic pain patients with suitable antidepressant medication, taking into account their individual health profiles and existing health issues.

A new study by researchers at the University of Gothenburg supports the notion that Selective Serotonin Reuptake Inhibitors (SSRIs) exert a specific antidepressant effect. Contrary to the 'placebo effect' theory, SSRIs are shown to be effective in treating depression, even in patients without side effects.
Researchers have identified serotonin's role in inhibiting a specific brain cell type, which may lead to faster-acting and more effective antidepressants. By targeting this protein, scientists hope to develop more targeted treatments with fewer side effects.
The study found a substantial increase in neonatal abstinence syndrome among infants whose mothers were prescribed opioids and psychotropic medications. The absolute risk was highest among women exposed to gabapentin, with concurrent exposure to psychotropic medications increasing severity of withdrawal symptoms.
A substantial number of US adults reported misusing prescription opioids, with 11.5 million admitting to misuse and 1.9 million having a use disorder. The majority of these individuals had low income or behavioral health problems, while relief from physical pain was the most common motivation for misuse.
A team of Rockefeller scientists has identified a specific type of nerve cell, called cholecystokinin (CCK)-expressing neurons, as the site where selective serotonin reuptake inhibitors (SSRIs) initiate their action. This discovery may pave the way for new antidepressants that act more quickly and produce fewer side effects.
A study found that pregnant women who took antidepressants were 45% more likely to have children diagnosed with autism, but the effect was limited. The research suggests that only a small proportion of cases would be prevented if antidepressant use was completely cut off during pregnancy.
A large Swedish study found a link between antidepressant use in pregnancy and autism risk, with 4.1% of exposed children developing autism compared to 2.9% of unexposed children. However, the absolute risk was small, and researchers stress that these results should not be considered alarming.
A study of 179,007 children found no association between antidepressant medication use and intellectual disability when other factors were considered. The researchers estimated a relative risk but it became statistically insignificant after adjusting for parental age and underlying psychiatric disorder.
A study examined the risk of intellectual disability (ID) in children born to mothers treated with antidepressants and found a slightly elevated risk, but it was not statistically significant. The researchers suggest that other factors such as parental age and psychiatric history may contribute to the risk.
Among patients unresponsive to an antidepressant, adding aripiprazole modestly increased remission rates from depression compared to switching or augmenting with bupropion. The study found symptom improvement was greater with aripiprazole than other treatments.
A new study from UT Southwestern Medical Center has identified the key protein responsible for ketamine's rapid antidepressant effects in the brain. The study reveals that ketamine blocks the N-methyl-D-aspartate (NMDA) receptor, creating an initial antidepressant reaction and extending its duration.
