Question

Quizplus · Accepted Answer

The majority of neuroscientists assume that the primary characteristic of Alzheimer's disease is the development of amyloid plaques, which are made up of beta-amyloid protein fragments that accumulate outside of neurons and interfere with communication between neurons. While tau and neurofibrillary tangles and neuron loss are also hallmarks of Alzheimer's disease, they are believed to be secondary to the accumulation of amyloid plaques. Memory problems and dementia are symptoms of Alzheimer's disease, but not its primary characteristic.
