A new study led by Hebrew University researchers Prof. Hermona Sorek and Prof.

Jonathan Levinstein has found a surprising molecular mechanism in the brains of Alzheimer's disease patients. The discovery is an essential step on the way to finding a drug suitable for women who suffer from it. The researchers found that the depletion of the stores of these RNA fragments in the brain reflects the rapid development of cognitive impairment among women with Alzheimer's. The findings shed new light on the mechanisms for controlling the development of Alzheimer’s disease among women.
