Some MCI patients go on to develop Alzheimer's disease within a few years, whereas other cases remain stable, exhibiting only benign senile forgetfulness. It is crucial to develop simple, blood-based tests enabling early identification of these patients that will progress in order to begin therapy as soon as possible, potentially delaying the onset of dementia. http://www.physorg.com/news175338556.html Medicine & Health Wed, 21 Oct 2009 10:30:04 EST news175338556 Individuals with ethanol in their bloodstreams appear less likely to die following a moderate to severe head injury, according to a report in the September issue of Archives of Surgery. http://www.physorg.com/news172770345.html Medicine & Health Mon, 21 Sep 2009 17:10:04 EST news172770345 New research finds poor money management skills may indicate that a person with mild memory problems will soon develop Alzheimer's disease.

The loss of these receptors has been difficult to study in living subjects, but Yale University researchers using advanced imaging technology have successfully tracked the loss of receptors with age, according to a report in the September issue of the journal Neurobiology of Aging. http://www.physorg.com/news171896029.html Medicine & Health Fri, 11 Sep 2009 14:20:01 EST news171896029 Researchers at the Institute of Biochemistry and Molecular Biology I of the Heinrich-Heine University, Düsseldorf, Germany, investigated the relationship between fruit and vegetable intake, plasma antioxidant micronutrient status and cognitive performance in healthy subjects aged 45 to 102 years. Their results, published in the August issue of the Journal of Alzheimer's Disease, indicated higher cognitive performance in individuals with high daily intake of fruits and vegetables. http://www.physorg.com/news171745580.html Medicine & Health Wed, 09 Sep 2009 20:30:02 EST news171745580 The belief that healthy older brains are substantially smaller than younger brains may stem from studies that did not screen out people whose undetected, slowly developing brain disease was killing off cells in key areas, according to new research. As a result, previous findings may have overestimated atrophy and underestimated normal size for the older brain. http://www.physorg.com/news171605735.html Medicine & Health Tue, 08 Sep 2009 05:30:01 EST news171605735 Patients infected with a particular subtype of HIV, the virus that causes AIDS, are more likely to develop dementia than patients with other subtypes, a study led by Johns Hopkins researchers shows.

Functional deficits in NMDA receptors may contribute to the underlying neurobiology of this disorder. The first generation of studies trying to stimulate NMDA receptors administered large amounts of substances, like glycine or D-serine, which indirectly enhance NMDA receptor function. While there were some positive reports of efficacy, findings across studies were more inconsistent than was hoped. http://www.physorg.com/news163738759.html Medicine & Health Tue, 09 Jun 2009 03:59:38 EST news163738759
