The growing number of drugs gaining U.S. FDA approval for Alzheimer’s disease has kept their ability to reduce amyloid beta and tau proteins in the news, but the degenerative disease is not simply a matter of tangles and deposits. A loss of synaptic plasticity and disrupted neural networks underlie the signature impairment of memory and cognition – and those, researchers showed in a recent study in Brain, can be strengthened by non-invasive stimulation that addresses the brain’s electrical dysfunction.
