Untangling Brain Neuron Dysfunction in Parkinson’s Disease and Dementia with Lewy Bodies

A decay of brain function is a hallmark of Parkinson’s disease and dementia with Lewy bodies, or DLB. Specifically, cognitive dysfunction defines DLB, and nearly eight of every 10 Parkinson’s patients develop dementia. In both of these neuro-degenerative diseases, aggregates of misfolded alpha-synuclein protein develop in brain neurons, including the hippocampus, the region of the […]

Novel Mechanism Found In a Severe Childhood Neurodegeneration

Neurology researchers investigating a rare but devastating neurological regression in infants have discovered the cause: gene mutations that severely disrupt crucial functions in mitochondria, the energy-producing structures within cells. The specific disease mechanism, in which mutations disrupt a critical mitochondrial enzyme, has not previously been implicated in a human disease. “We uncovered the cause of […]

Dysfunctional Endosomes Are An Early Sign of Neurodegeneration

Writing in the April 11 issue of The Journal of Clinical Investigation, researchers at University of California, San Diego School of Medicine say abnormalities in a protein that helps transport and sort materials inside cells are linked to axonal dysfunction and degeneration of neurons in Alzheimer’s disease (AD) and Down syndrome (DS). “Amyloid plaques and […]
