Study confirms pathogenic role of beta amyloid in dementia as seen in AD and Down syndrome

More than five million Americans are living with Alzheimer's disease (AD). Of them, 400,000 also have Down syndrome. Both groups have similar looking brains with higher levels of the protein beta amyloid.

Wavelet transform approach could improve medical imaging

An approach to converting the data from MRI (magnetic resonance imaging) machines, mammograms and other medical equipment gives doctors a much clearer picture of your insides and a chance to detect disease and other problems earlier, according to research published in the International Journal of Biomedical Engineering and Technology.

Modified Story Memory Technique improves memory in adults with moderate to severe TBI

Kessler Foundation researchers published results of a randomized clinical trial (RCT) of a cognitive intervention to improve learning and memory in individuals with traumatic brain injury (TBI) - the TBI-MEM trial.

New model of cognitive flexibility may help understand behavioral, neurological disorders

Cognitive flexibility is the ability to shift our thoughts and adapt our behavior to the changing environment. In other words, it's one's ability to disengage from a previous task and respond effectively to a new one.

Diabetes may be linked to buildup of brain tangles associated with Alzheimer’s disease

Diabetes may be linked to the buildup of tangles or tau in the brain, separate from Alzheimer's disease, according to a new study published in the September 2, 2015, online version of Neurology, the medical journal of the American Academy of Neurology.

SKA2 gene may play a role in development of PTSD

A gene linked in previous research, appears to predict more severe post-traumatic stress disorder (PTSD) symptoms as well as a thinner cortex in regions of the brain critical for regulating strong emotions and coping with stressful experiences. This study is believed to be the first to show that the spindle and kinetochore-associated complex subunit 2 (SKA2) gene may play a role in the development of PTSD.

Automated speech analysis program correctly identifies young people at risk for psychosis

An automated speech analysis program correctly differentiated between at-risk young people who developed psychosis over a two-and-a-half year period and those who did not. In a proof-of-principle study, researchers at Columbia University Medical Center, New York State Psychiatric Institute, and the IBM T. J. Watson Research Center found that the computerized analysis provided a more accurate classification than clinical ratings.

Cognitive factors associated with activity, participation in everyday life among people with MS

Kessler Foundation researchers found that processing speed is the primary limiting factor associated with activity and participation in everyday life among people with multiple sclerosis (MS). "Factors that moderate activity limitation and participation restriction in people with multiple sclerosis" was published in the American Journal of Occupational Therapy.

Temporary postnatal visual deprivation induces permanent auditory responses in the brain's visual area

A brief period of postnatal visual deprivation, when early in life, drives a rewiring of the brain areas involved in visual processing, even if the visual restoration is completed well before the baby reaches one year of age, researchers at the University of Trento, McMaster University, and the University of Montreal revealed today in Current Biology.

Researchers find effectiveness of ramelteon for treatment of sleep disturbances after TBI

Kessler researchers found preliminary evidence for the effectiveness of ramelteon for the treatment of sleep disturbances after traumatic brain injury (TBI). The article, "Archives of Physical Medicine and Rehabilitation on May 28, 2015. Authors are Anthony Lequerica, PhD, and Nancy Chiaravalloti, PhD, of Kessler Foundation, Neil Jasey, MD, of Kessler Institute for Rehabilitation, and Jaclyn Portelli Tremont, MA, of Robert Wood Johnson Medical School, Rutgers University.

New study offers first clinical recommendations for headache diagnosis in pregnant women

If a pregnant woman with high blood pressure and no history of headache suddenly develops a headache that quickly gets worse, she could be at risk for pregnancy complications, including preeclampsia, which put both the mother and fetus at risk.

CMU BrainHub scientists use non-invasive brain-imaging tool to detect basal ganglia pathways

Certain diseases, like Parkinson's and Huntingdon's disease, are associated with damage to the pathways between the brain's basal ganglia regions. The basal ganglia sits at the base of the brain and is responsible for, among other things, coordinating movement. It is made up of four interconnected, deep brain structures that imaging techniques have previously been unable to visualize.

Early exposure to repetitive head impacts linked to later life structural brain changes among former NFL players

Former National Football League (NFL) players who started playing tackle football before the age of 12 were found to have a higher risk of altered brain development compared to those who started playing at a later age. The study is the first to demonstrate a link between early exposure to repetitive head impacts and later life structural brain changes.
