People with alzheimer's disease have brain neurons that die?

Yes, individuals with Alzheimer's disease experience the death of brain neurons, which contributes to the progressive decline in cognitive function. This neuronal loss is often associated with the accumulation of abnormal protein deposits, such as amyloid plaques and tau tangles, which disrupt communication between neurons. As more neurons die, it leads to memory loss, difficulties in thinking and reasoning, and changes in behavior. Overall, the degeneration of brain cells is a key factor in the progression of Alzheimer's disease.
