Study using unique 3D lab cultures appears to confirm how Alzheimer’s begins in brain
The Washington Post

A group of New England scientists say they have confirmed what Alzheimer’s disease researchers have long theorized but had been unable to prove: the brain-killing illness is caused by the deposit of a protein in the brain, known as beta amyloid, that triggers a devastating series of dementia-causing events.

Scientists at Massachusetts General Hospital also identified an enzyme that plays a key role in the progression of the disease — thereby offering a target for pharmacy-makers to develop a drug that would halt the neurodegenerative disease.
