Spread of tau protein measured in the brains of Alzheimer’s patients
[PRESS RELEASE 2017-05-16] In a new study presented in Molecular Psychiatry, researchers at Karolinska Institutet have measured how deposits of the pathological protein tau spread through the brain over the course of Alzheimer’s disease. Their results show that the size of the deposit and the speed of its spread differ from one individual to the next, and that large amounts of tau in the brain can be linked to episodic memory impairment.Already in a very early phase of Alzheimer’s disease there is an accumulation of tau in the brain cells, where its adverse effect on cell function causes
