Link between Alzheimer's disease and traumatic brain damage clarifiedAugust 04, 2005Leuven, Belgium - This week scientists of the Flanders Interuniversity Institute for Biotechnology (VIB) will once again publish a breakthrough in their research regarding Alzheimer's disease. The researchers, this time connected to the Catholic University of Leuven, discovered the function of one of the most important proteins related to Alzheimer's disease. They have indicated that the protein stimulates the growth of nerve paths in the brain, which is essential for recovery after brain damage. The results are published in the authoritative journal EMBO Journal. The normal function of the amyloidal precursor protein or APP clarified It has been known for several years that APP is relevant in Alzheimer's disease. APP is the precursor of the amyloidal-â protein that causes the typical 'plaques' in the brains of patients. The normal function of APP was, however, not known. Maarten Leyssen and his colleagues have indicated that APP stimulates the development of nerve paths. Intact nerve paths are essential for the proper functioning of the brain. These connections can be damaged after traumatic brain damage resulting in the improper functioning of the brain. APP is responsible for stimulating the development of new nerve paths. APP and Alzheimer's disease
These results also aid better understanding of certain aspects of Alzheimer's disease, where APP plays a major role. The fruit fly - an ideal model to study the brain's action - indicates that APP increases considerably after brain damage, namely in areas where new nerve paths need to be formed. Because more APP is made, more plaques can develop in the brain, a typical symptom of Alzheimer's disease. For the first time the results of VIB researchers explain the strong link between brain damage and Alzheimer's disease: not only do patients with major brain damage have more chance of developing Alzheimer's disease later on in life, their brains also often show plaques that strongly resemble those of Alzheimer patients.

New imaging compound might 'see' Alzheimer's earlier A new imaging molecule that can detect and map plaques and tangles in the brains of people with Alzheimer's disease could eventually lead to earlier diagnosis of the devastating disease, researchers at the University of California, Los Angeles report in the Dec. 21, 2006, issue of the New England Journal of Medicine. Testosterone therapy may prevent Alzheimer's disease Researchers at the University of Southern California have discovered a direct link between loss of testosterone and the development of an Alzheimer's-like disease in mice. They also discovered that testosterone treatment slows progression of the disease. Androgen therapy may slow progress of Alzheimer's disease Experiments on mouse models of Alzheimer's disease (AD) suggest that treatment with male sex hormones might slow its progression. Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease Scientists collaborating at Cornell University in Ithaca and Weill Cornell Medical College in New York City have identified a panel of 23 protein biomarkers in cerebrospinal fluid that acts as a neurochemical "fingerprint," which doctors might use someday to identify patients living with Alzheimer's disease. Study shows cats can succumb to feline Alzheimer's disease Ageing cats can develop a feline form of Alzheimer's disease, a new study reveals. Scientists at the Universities of Edinburgh, St Andrews, Bristol and California have identified a key protein which can build up in the nerve cells of a cat's brain and cause mental deterioration. Scientists develop a new way to target Alzheimer's disease The pathological embrace between two proteins plays a key role in the development of Alzheimer's disease by triggering the formation of neuron-killing plaques of amyloid beta protein. Now a group of scientists at NYU School of Medicine have devised a way to reduce amyloid beta deposition by interfering with the deadly embrace of these proteins.
