Link unlikely between insomnia symptoms, high blood pressure, study concludes

Link unlikely between insomnia symptoms, high blood pressure, study concludes

There’s good news for the 30 per cent or more of adults who suffer from insomnia–difficulty falling asleep, waking up for prolonged periods during the night or unwanted early morning awakenings. New research from St. Michael’s Hospital has found that insomnia does not put them at increased risk of developing high blood pressure. Continue reading

Schizophrenia and cannabis use may share common genes

Schizophrenia and cannabis use may share common genes

Genes that increase the risk of developing schizophrenia may also increase the likelihood of using cannabis, according to a new study led by King’s College London, published today in Molecular Psychiatry. Previous studies have identified a link between cannabis use and schizophrenia, but it has remained unclear whether this association is due to cannabis directly increasing the risk of the disorder.

Single dose of century-old drug approved for sleeping sickness reverses autism-like symptoms in mice

Single dose of century-old drug approved for sleeping sickness reverses autism-like symptoms in mice

In a further test of a novel theory that suggests autism is the consequence of abnormal cell communication, researchers at the University of California, San Diego School of Medicine report that an almost century-old drug approved for treating sleeping sickness also restores normal cellular signaling in a mouse model of autism, reversing symptoms of the neurological disorder in animals that were the human biological age equivalent of 30 years old. The findings, published in the June 17, 2014 online issue of Translational Psychiatry , follow up on similar research published last year by senior author Robert K. Continue reading

Children showing signs of social withdrawal in risk of internalized distress

Children showing signs of social withdrawal in risk of internalized distress

Children showing signs of social withdrawal are more susceptible to parental influences than others. These children were also more prone to distress caused by the impacts of guilt-inducing parenting. The researchers of the University of Jyväskylä, Finland followed up about 300 children across the first three years of primary school and monitored the children’s social skills and problem behaviors.

MRI brain scans detect people with early Parkinson’s

MRI brain scans detect people with early Parkinson’s

Oxford University researchers funded by Parkinson’s UK have developed a simple and quick MRI technique that offers promise for early diagnosis of Parkinson’s disease. The team demonstrated that their new MRI approach can detect people who have early-stage Parkinson’s disease with 85% accuracy, according to research published in Neurology , the medical journal of the American Academy of Neurology.

Inside the adult ADHD brain: Differences between adults who have recovered, and those who have not

About 11 percent of school-age children in the United States have been diagnosed with attention deficit hyperactivity disorder (ADHD). While many of these children eventually “outgrow” the disorder, some carry their difficulties into adulthood: About 10 million American adults are currently diagnosed with ADHD. Continue reading

Creatures of habit: Disorders of compulsivity share common pattern, brain structure

Creatures of habit: Disorders of compulsivity share common pattern, brain structure

People affected by binge eating, substance abuse and obsessive compulsive disorder all share a common pattern of decision making and similarities in brain structure, according to new research from the University of Cambridge. In a study published in the journal Molecular Psychiatry and primarily funded by the Wellcome Trust, researchers show that people who are affected by disorders of compulsivity have lower grey matter volumes (in other words, fewer nerve cells) in the brain regions involved in keeping track of goals and rewards. In our daily lives, we make decisions based either on habit or aimed at achieving a specific goal. Continue reading
