The brain's own "clean up command": Alzheimer's researchers say that some plagues are beneficial

A study reveals that there are crucial differences in the protein deposits in the brain that are typical of Alzheimer's disease.   According to this, the diffuse accumulations of amyloid beta protein are more deadly to brain cells than plaques with a dense, compact core. A key feature of   Alzheimer's disease   is the accumulation of insoluble clumps of misfolded amyloid beta proteins in the brain.   According to current theory, these plaques impede brain metabolism and promote the death of neurons.   That is why the plaques are seen as a promising starting point for therapies against progressive brain atrophy.   So far, however, tests of such anti-plaque agents have often produced   disappointing results   .     Alzheimer's: Difference Between Diffuse and Dense Plaques A possible explanation for this could now have been found by a team led by Youtong Huang from the Salk Institute for Biological Studies in California.   Because not all amyloid plaques are created equal.
