Biological Marker For Alzheimer's Holds Promise For Earlier Diagnosis And Treatment

ScienceDaily (July 12, 2008) — Researchers at Robarts Research Institute at The University of Western Ontario have found clear evidence that increases in the size of the brain ventricles are directly associated with cognitive impairment and Alzheimer’s disease.

Ventricles are fluid-filled cavities in the brain. The research, led by Robarts scientist Robert Bartha, shows the volume of the brain ventricles expands as surrounding tissue dies.
Currently, diagnosis for Alzheimer’s relies on neuro-cognitive assessments, such as testing of memory, ability to problem solve, count, etc. Definitive diagnosis is not possible until after death when an autopsy can reveal the presence of amyloid plaques and ‘tangles’ in brain tissue.
Previous research has shown the link between ventricle size and Alzheimer’s over longer time intervals.
