Daily use of cannabis with high concentrations of THC is linked to an increased risk of experiencing psychosis-like symptoms.
During memory tasks, people with psychosis have different patterns of activity in the prefrontal and mediotemporal brain areas compared to those without the disorder. When exposed to cannabidiol (CBD), the activity of the brain areas became more like those seen in the controls for people with psychosis. Patients reported a decrease in symptoms of psychosis following one dose of CBD. Researchers stress that no definitive conclusions could be made about the effectiveness of CBD use over a sustained period.
A new investigation into interneuron development sheds light on how disorders associated with neurodevelopment, such as autism and schizophrenia may occur.
Researchers report an exaggerated immune response can trigger chronic fatigue syndrome. The study reveals levels of Il-10 were higher in those who developed lasting fatigue, suggesting the immune system may have been primed to over respond.
Mouse study reveals intermittent fasting improves long-term memory retention and promotes hippocampal neurogenesis. The findings could help to slow cognitive decline in older adults.
Diet and exercise can influence hippocampal neurogenesis, researchers say. Poor nutrition and lack of exercise have detrimental effects on hippocampal neurogenesis, increasing the risk for dementia.
The genes GRB10 and ABTB1 are influential in nutrient-sensing pathways and memory. Researchers say these genes may be the molecular links between diet, neural stem cell aging, and cognitive ability.
People who suffer from REM behavioral disorder, a sleep disorder linked to an increased risk of developing Parkinson's disease, exhibit limited movement of their trunk during dream re-enactment.
