Young adults with a genetic variant that raises their risk of developing Alzheimer's Disease show changes in their brain activity decades before any symptoms might arise, according to a new brain imaging study by scientists from the University of Oxford and Imperial College London. The results may support the idea that the brain's memory function may gradually wear itself out in those who go on to develop Alzheimer's.

Preliminary research examining the difference in brain activity between soldiers with post-traumatic stress disorder and those without it moves scientists a step closer to the possibility of being able one day to use brain scans to help diagnose the condition.

Young children who do not display an ability to regulate their behavior or to delay gratification in exchange for a larger reward appear predisposed to gain extra weight by their pre-teen years, according to two reports published in the April issue of Archives of Pediatrics & Adolescent Medicine.

Some of the symptoms of the autistic condition Asperger Syndrome, such as a need for routine and resistance to change, could be linked to levels of the stress hormone cortisol, suggests new research led by the University of Bath.

Researchers at the Swedish medical university Karolinska Institutet (KI) have constructed a mathematical activity model of the brain's anterior and superior parts, to increase the understanding of the capacity of the working memory and of how the billions of neurons in the brain interact.

Scientists from The New York State Office of Mental Retardation and Developmental Disabilities’ (OMRDD) New York State Institute for Basic Research in Developmental Disabilities (IBR) report in the Journal of Alzheimer’s Disease that anesthesia induces phosphorylation of tau. Tau is a key neuronal protein involved in neurodegeneration in Alzheimer’s disease (AD) and several other neurodegenerative disorders.
