Chronic Stress Spawns Protein Aggregates Linked to Alzheimer's
Repeated stress triggers the production and accumulation of insoluble tau protein aggregates inside the brain cells of mice, say researchers at the University of California, San Diego School of Medicine.

"Acute stress may be useful for brain plasticity and helping to facilitate learning. Chronic stress and continuous activation of stress pathways may lead to pathological changes in stress circuitry. It may be too much of a good thing."

Brain Imaging Studies Suggest Alzheimer’s Disease Spreads Through Linked Nerve Cells
Alzheimer's disease and other forms of dementia may spread within nerve networks in the brain by moving directly between connected neurons, instead of in other ways proposed by scientists, such as by propagating in all directions, according to researchers who report the finding in the March 22 edition of the journal Neuron.
