Age-related dementia may begin with neurons’ inability to dispose of unwanted proteins

A team of European scientists has taken an important step closer to understanding the root cause of age-related dementia. In research involving both worms and mice, they have found that age-related dementia is likely the result of a declining ability of neurons to dispose of unwanted aggregated proteins. As protein disposal becomes significantly less efficient with increasing age, the buildup of these unwanted proteins ultimately leads to the development and progression of dementia.
