People with mild cognitive impairment who had positive biomarkers for Alzheimer's disease in their cerebrospinal fluid performed worse on virtual reality navigation tasks. Virtual reality which incorporates navigational tasks could prove a helpful tool in the early diagnosis of Alzheimer's disease for those at risk.
People diagnosed with Alzheimer's or mild cognitive impairment had weaker gamma wave activation in their brains than their peers without the neurodegenerative disorders.
Subtle changes in thinking and memory may appear before, or in conjunction with, the development of amyloid plaques.
A new study reports women may retain better verbal memory during the early stages of Alzheimer's than men, despite evidence of similar levels of hippocampal shrinkage.
Verbal tests for MCI might not pick up symptoms in women until they are further along into the progression of Alzheimer's disease, researchers report.
