If neuronal autophagy declines in a patient with developing Alzheimer's disease, which consequence follows regarding neurodegenerative pathology?

A)Amyloid plaque formation decreases
B)Tau protein aggregate accumulation increases
C)Neurofibrillary tangle formation slows
D)Synaptic vesicle recycling improves

💡 Explanation

When autophagy declines, the clearance of misfolded proteins, such as tau, is impaired. Because of reduced clearance via the autophagy pathway, tau protein aggregates accumulate, therefore exacerbating neurodegenerative pathology, rather than other processes like plaque formation being inhibited.
