Social isolation increases anxiety and asymmetry in brain atrophy in Alzheimer's disease

(Universitat Autonoma de Barcelona) A study in mice conducted by the UAB shows that social isolation worsens the effects of Alzheimer's disease, with hyperactivity levels reaching up to twice as much as in the pathology itself, and confirms an increase in the asymmetric atrophy of the hippocampus, a brain area central to memory. The study was published in a special edition of Frontiers in Psychiatry entitled Death and Mourning Processes in the Times of the Coronavirus Pandemic (COVID-19).
