Humans have long fixated on which mental traits distinguish us from other animals. Now, University of Arizona researchers are asking what our canine companions can tell us about ourselves.

Long before they develop neurofibrillary tangles or beta-amyloid plaques, brains with Alzheimer’s disease begin experiencing problems in their cells’ power plants — the mitochondria — that hinder their ability to make energy for cells.
Declines in gene expression related to mitochondria can occur in subjects as young as their early 30s.
