Alzheimer’s disease is a chronic neurodegenerative disease that most often begins in people over 65 years of age. Usually it starts slowly and continues to worsen over time until the sufferer succumbs to an increasing loss of memory, bodily functions and, eventually, death. Research has shown that there is an association with Alzheimer’s and the accumulation of plaques that affect the neuronal connections in the brain. Now researchers at the University of Queensland have discovered a new way to remove these toxic plaques using a non-invasive form of ultrasound therapy.
Amyloid-β (Aβ) peptide – composed of some 36 to 43 amino acids – has been the plaque associated with the development and progression of Alzheimer’s disease for some time now. As such, some research into removing this toxic substance from human brains has been conducted, but almost invariably requires invasive pharmaceutical intervention which is far from completely effective.
