A new study, published in the JAMA Psychiatry medical journal, finds a link between the postnatal depression in fathers and mental health issues in their daughters later on.
However, fathers’ mental health has no that effect on sons, according to researchers from the universities of Cambridge, Bristol, Oxford, and Imperial and UCL in London. The scientists think this is due to the fact that girls may be more sensitive to the way their fathers interact with them as a baby.
The authors of the study say in their paper: “We have found girls with fathers with depression during the postnatal period are at risk of developing depression after puberty, but such risk is not seen in boys.”
A new study, published in the journal Neurology, suggests that a six-month regimen of aerobic exercise may reverse the mild cognitive impairment (MCI) in senior adults.
To study the effect of exercising, a team of researchers included 160 people with the average age 65 years who lead a sedentary way of life at the beginning of the study and had the risk of cardiovascular disease and symptoms of MCI.
The participants were divided into four groups: one group did aerobic exercises, the second adhered to the DASH diet without exercising, the third group did exercises and ate according to the DASH diets, the fourth group only received health-related educational phone calls.
Lead researcher James A. Blumenthal, Ph.D. of Duke University Medical Center in Durham, NC, says: “The results are encouraging in that in just 6 months, by adding regular exercise to their lives, people who have cognitive impairments without dementia may improve their ability to plan and complete certain cognitive tasks.”
According to a recent European study, persistent bullying can cause the reshape of the developing brain of teenagers.
For the study, a team of researchers took data from the long-term study on teenage brain development and mental health collected from 682 teens aged from 14 to 19 from England, Ireland, France, and Germany.
Lead study author Erin Burke Quinlan from King’s College London comments: “Although not classically considered relevant to anxiety, the importance of structural changes in the putamen and caudate to the development of anxiety most likely lies in their contribution to related behaviors such as reward sensitivity, motivation, conditioning, attention, and emotional processing.”
A new study, conducted by scientists from the Karolinska Institute and Stockholm University, Sweden, suggests that atrial fibrillation is associated with the increased risk of developing dementia.
For the study, a team of researchers has analyzed the data of 2,685 participants whose average age was 73 years. The scientists interviewed the participants and conducted a medical examination at baseline. After that, the participants younger than 78 was followed for 6 years, and the participants older than 78 were examined every 3 years.
The researchers explain in their paper: “Assuming that there was a cause-and-effect relationship between using blood thinners and the reduced risk of dementia, we estimated that about 54 percent of the dementia cases would have been hypothetically prevented if all of the people with atrial fibrillation had been taking blood thinners.”
Researchers from Florida Atlantic University, US, have found a new pathway in the brain associated with the behavioral symptoms of autism spectrum disorder (ASD) and a drug to quell these symptoms.
The drug treated the behavioral disruptions in mice with autism. Scientists believe that it may have the same effect for adults with the condition.
Firstly, 25 years ago, it was discovered that a genetic mutation interferes with the serotonin regulation in people with autism. Serotonin is a key neurotransmitter to the feeling of happiness and plays important role in social functioning.
Then, a particular enzyme was found that had a drastic effect on the reabsorption of serotonin. After that, an experimental compound called MW150 was developed and tested on mice.
