Women at increased risk of postpartum psychosis show altered connectivity in networks of the brain responsible for planning, organisation and the completion of short and long-term tasks. Currently, there are no biological markers that identify who will develop postpartum psychosis. But researchers from King’s College London have identified altered connectivity in the brain networks of women with postpartum psychosis, which could pave the way for better identifying women at risk of the condition.

The findings of a new study on diabetes and dementia were presented at the annual meeting of the European Association for the Study of Diabetes. The results of the study may be able to help reduce the risk of dementia in diabetic patients with poor glycemic control. “Our study looks at the link between diabetes and the risk of developing dementia and Alzheimer’s diseases,” study author Dr. Carlos Celis-Morales told us. "We would like to better understand the link between diabetes but also glycemic control with dementia risk and whether these associations are explained by existing risk factors such as being obese, a smoker or having existing heart diseases or other chronic diseases.” [More]

Did you know that adults need an average of seven to nine hours of sleep per day and that adolescents need eight to ten hours? According to statistics from the Institute of Medicine, American adults and teens aren’t getting enough sleep. How does lack of sleep or sleep deprivation affect our brain’s reward system? An average of 50-70 million American adults have a sleep disorder. The most common sleep disorder is insomnia. Approximately 30 per cent of American adults say they have experienced short term insomnia while 10 per cent say they experience chronic insomnia. A new study published in eNeuro looked at sleep-deprivation and rewards using mice and cocaine. [More]
