Impaired glucose metabolism, insulin resistance, neuroinflammation, and reduced neuronal plasticity have been implicated in depression and other mood disorders. GLP-1 receptor agonists (medications like Ozempic) may help improve these risk factors, which has led to research investigating GLP-1 receptor agonists in psychiatric disorders.

A recent large study analyzed data from a nationwide Swedish database of patients and reported that patients with bipolar disorder who were taking semaglutide (also known as Ozempic or Wegovy) had significantly lower rates of psychiatric hospitalizations compared to times when they were not taking a GLP-1 medication. However, this pattern was not observed with liraglutide and dulaglutide.

Further research using controlled study designs are required to better understand the potential link between GLP-1 receptor agonists and psychiatric outcomes.

A study published in JAMA Network Open investigated changes in brain function during cognitive tasks in cannabis users. Overall, they found that greater cannabis use was associated with lower brain activation during a working memory task, particularly in the dorsolateral prefrontal cortex, dorsomedial prefrontal cortex, and anterior insula.

These findings add to our understanding of how cannabis use can impact the brain.

Research conducted at the Institute of Psychiatry, Psychology & Neuroscience at King’s College reported that individuals who started using cannabis to self-medicate an illness, including physical pain, anxiety, and depression, had higher paranoia scores and reported higher levels of cannabis use. Also, individuals who reported childhood trauma had greater cannabis use.

This research indicates the significant risk to health and well-being associated with using cannabis to cope with physical and emotional pain.

This research sheds light on how cannabis use can influence the way the brain processes information.
