Rapid Image Analysis Method Helps Diagnose Alzheimers Disease
ScienceDaily, 02/18/2010
|
MR images in just a few minutes when diagnosing Alzheimer's disease. The accuracy of the analysis is comparable to manual measurements made by skilled professionals, which are currently considered the most reliable method for diagnosing Alzheimer's disease. The accurate and rapid analysis method is ... Alzheimer's disease requires that the patient displays some other symptom or sign of Alzheimer's disease in addition to memory problems. Such other symptoms include atrophy, i.e. the loss of brain cells, visible in MR images.

Experiments shed new light on Alzheimers disease
Health and Age, 02/25/2010
|
Alzheimer’s disease affects around half of the 700,000 people with dementia in the UK and this figure is set to increase sharply in years to come, with similar trends expected in other countries because of the aging of the population. Therefore ... of diagnosing and treating Alzheimer’s disease. Research from a team in New York now suggests that loss of the sense of smell might be an early symptom of Alzheimer’s disease, opening up the possibility of a new way of diagnosing the condition. Experiments in mice suggest that deficits in the sense ... build up of amyloid protein, which is the hallmark of Alzheimer’s disease.

Assessment and familial aggregation of psychosis in Alzheimer’s disease from the National Institute on Aging Late Onset Alzheimer’s Disease Family Study
Brain, 02/23/2010
|
Sweet R et al. – The found that reliable assessments of psychotic symptoms during in–person or phone interviews were readily ... Alzheimer’s disease was significantly associated with degree of cognitive impairment, and significantly, albeit modestly, correlated with the severity of other behavioural symptoms. Psychosis significantly aggregated within late onset Alzheimer’s disease families suggesting that it may identify a

Damaged protein identified as early diagnostic biomarker for Alzheimer's disease in healthy adults
EurekAlert, 02/24/2010
|
The study shows that high levels of P– tau231 predict future memory decline and loss of brain gray matter in the medial temporal lobe– a key memory center. Prior studies found the medial ... early stages of Alzheimer's disease accumulating damaged tau proteins in the form of neurofibrillary tangles. Tangles are one of the signature indicators of Alzheimer's disease, in addition to beta amyloid plaques.

Neuroimaging Study Describes Alzheimer's Disease-Like Changes in Elderly People Without the Disease
ScienceDaily, 03/17/2010
|
The emergence of multiple new brain imaging technologies and the combined application of these new approaches is helping to create new insights into aging and Alzheimer's disease. One of the hallmarks of Alzheimer's disease is ... the deposition of amyloid beta protein in clumps or "plaques" within the brain. These plaques can be measured in humans with PET scans that use a chemical marker or radiotracer called 11C–PIB.

Allan CL et al. – The development of acetyl–cholinesterase inhibitors, and the prospect of future therapies to prevent, or modify, the course of Alzheimer's disease necessitates greater accuracy in diagnosis of this heterogeneous disease ... of sensitive and specific biomarkers would enable earlier and more accurate diagnosis. Genetic markers, such as Apolipoprotein E4, and cerebrospinal fluid markers such as beta–amyloid and tau, support a diagnosis of Alzheimer's disease.

Maurizi CP – Melatonin is a potent antioxidant and the loss of its protection in the cerebrospinal fluid in Alzheimer’s disease can explain the pattern of cell destruction. Challenges of the embedded ... been ignored; however this old faulty theory must be abandoned in order to understand the pathophysiology of Alzheimer’s disease.
