Question

Quizplus · Accepted Answer

The current consensus among neuroscientists is that the primary symptom of Alzheimer's disease is the development of amyloid plaques, which are abnormal clusters of protein fragments that build up between neurons in the brain. While memory problems and dementia are common symptoms of Alzheimer's, they are thought to be secondary to the underlying pathology of amyloid plaque formation. Tau and neurofibrillary tangles and neuron loss are also associated with Alzheimer's, but are not considered to be the primary symptom.
