Kids who are abused or bullied may age faster

The study finds that violence-related stress in children affects telomeres - special DNA sequences found at the tips of chromosomes. Telomeres, which prevent DNA from unravelling, get shorter each time cells divide, which limits the number of times cells can divide. Shorter telomeres have been linked to poorer survival and chronic diseases. Previous research has shown that smoking, obesity, mental-health disorders and stress may accelerate the process of telomere loss. This suggests that telomere length may reflect a person's biological age as well as their chronological age.

AANF changes name to American Brain Foundation

The American Academy of Neurology Foundation is now the American Brain Foundation. The name change is part of an overall re-branding campaign as the organization repositions itself to become the world's leader in raising money for research to cure brain diseases, such as Alzheimer's disease, stroke, Parkinson's disease, autism, and epilepsy.

Link between binge eating and addiction-like behaviors

A history of binge eating -- consuming large amounts of food in a short period of time -- may make an individual more likely to show other addiction-like behaviors, including substance abuse, according to Penn State College of Medicine researchers. In the short term, this finding may shed light on the factors that promote substance abuse, addiction, and relapse. In the long term, may help clinicians treat individuals suffering from this devastating disease.

Stress can shorten telomeres at a very young age

Children who have experienced violence might really be older than their years. The DNA of 10-year-olds who experienced violence in their young lives has been found to show wear and tear normally associated with aging, a Duke University study has found.

Neuron-killing pathology of AD requires presence of a-beta and elevated p-tau levels

According to a new study, the neuron-killing pathology of Alzheimer's disease (AD), which begins before clinical symptoms appear, requires the presence of both amyloid-beta (a-beta) plaque deposits and elevated levels of an altered protein called p-tau.

Chronic cocaine abuse accelerates process of brain ageing

New research by scientists at the University of Cambridge suggests that chronic cocaine abuse accelerates the process of brain ageing. The study, published today 25 April in Molecular Psychiatry, found that age-related loss of grey matter in the brain is greater in people who are dependent on cocaine than in the healthy population.

Preventive treatments can reduce migraine attacks

Research shows that many treatments can help prevent migraine in certain people, yet few people with migraine who are candidates for these preventive treatments actually use them, according to new guidelines issued by the American Academy of Neurology.

Exergames have significant benefits for older adults

Videogame technology is proving to be a valuable tool for helping people of all ages improve lifestyle and health habits and manage disease. New research is showing that exergames have significant benefits for older adults by providing cognitive stimulation and a source of social interaction, exercise, and fun.

TopBP1 protein prevents early brain cells from DNA damage

St. Jude Children's Research Hospital scientists have rewritten the job description of the protein TopBP1 after demonstrating that it guards early brain cells from DNA damage. Such damage might foreshadow later problems, including cancer.

HDAC6 protein may provide novel target for stress-linked disorders

A cellular protein called HDAC6, newly characterized as a gatekeeper of steroid biology in the brain, may provide a novel target for treating and preventing stress-linked disorders, such as depression and post-traumatic stress disorder (PTSD), according to research from the Perelman School of Medicine at the University of Pennsylvania.

Liver may be the key to weight regulation: Study

A team of Australian researchers have found that the liver could hold the key to treating obesity. They found that the liver plays a major role in regulating weight by communicating with the brain. The study will be published in the Journal Diabetes.

Study shows how cocaine changes the shape and size of neuron rewards in mouse model

New research from Mount Sinai Medical Center in New York reveals that repeated exposure to cocaine decreases the activity of a protein necessary for normal functioning of the brain's reward system, thus enhancing the reward for cocaine use, which leads to addiction. Investigators were also able to block the ability of repeated cocaine exposure, to induce addiction.

SUMO protein regulates transfer of information between nerve cells in the brain

A key protein, which may be activated to protect nerve cells from damage during heart failure or epileptic seizure, has been found to regulate the transfer of information between nerve cells in the brain. The discovery, made by neuroscientists at the University of Bristol and published in Nature Neuroscience and PNAS, could lead to novel new therapies for stroke and epilepsy.
