A Beta-Amyloid, which serves as Trigger for Alzheimer's, Identified

Researchers from the University of Virginia and German biotech company Probiodrug have identified a beta amyloid, called as the pyroglutamylated (or pyroglu) beta-amyloid, which enhances the toxicity of other beta-amyloids in the brain and may act as a possible trigger for Alzheimer’s disease. The findings of the research have been published in the latest online issue of the journal Nature. The research, which was led by George Bloom, found that the pyroglutamylated beta- amyloid acts on the...

Perceptual Capacity greater in Individuals with Autism Spectrum Disorders

In a new study, published in the latest issue of the Journal of Abnormal Psychology, researchers led by Dr. Anna M. Remington have found that under higher levels of load, the perceptual capacity of individuals with Autism Spectrum Disorders is more as compared to typical adults. This implies that individuals suffering from autism are able to better process information even with faster than normal presentations. This capacity is higher than in people who do not suffer from autism. Professor...

  A new study shows that the stem cells, transplanted in rats who have suffered from brain injury, help in functional recovery. The study has been published in the February issue of Neurosurgery, the official journal of the Congress of Neurological surgeons. The research was led by Dr. Toshiya Osanai from the Hokkaido University Graduate School of Medicine, Japan.   The researchers recovered the stem cells from the rat’s bone marrow and transplanted them directly onto the brain seven days...

A recent study published in the Journal “Stroke” has found that patients suffering from lung cancer are at a higher risk of developing stroke. The study, conducted by Taiwanese researchers, covered 52,089 patients suffering from lung cancer between 1999 and 2007 and 104,178 matched non cancer patients. The incidence of stroke in the participants was measured until 2008, and the association between lung cancer and the hazard of developing stroke was estimated.    The researchers found that...

  According to a new American Heart Association/American Stroke Association scientific statement published online in “Stroke: Journal of the American Heart Association”, the atherosclerotic changes in the vessels that lead to various heart diseases have also been linked to age-related vascular cognitive impairments (VCI), also called as dementia. The highlights of the statement include: • A high blood pressure can lead to VCIs. • A healthy heart is linked to a healthy brain. •...
