Protecting the brain from dementia-inducing abnormal protein aggregates

Neurodegenerative diseases like Alzheimer's and Parkinson's are defined by pathogenic accumulation of toxic proteins in the brain. Now, however, scientists have established that the p62 protein, which is involved in cellular protein degradation, can prevent the accumulation of toxic oligomeric tau species in mouse brains, proving the 'neuroprotective' function of p62 in a living model.

When more is more: Identifying cognitive impairments with multiple drawing tasks

Researchers have found that extracting drawing features from a combination of five drawing tasks -- rather than from any single task alone -- leads to more accurate classification of people with normal cognition, mild cognitive impairment, and Alzheimer's disease by capturing different, complementary aspects of cognitive impairments. Their proposed portable, easy-to-use screening test may improve patient diagnosis, leading to earlier and more effective treatments.
