← Human Body & HealthIf therapeutic ultrasound is applied to the brain of a patient with Alzheimer's disease, which consequence follows regarding amyloid-beta aggregates?
A)Accelerated amyloid plaque formation occurs
B)Increased neuroinflammation response dominates
C)Tau protein aggregation is directly stimulated
D)Microglial phagocytosis of aggregates increases✓
💡 Explanation
Ultrasound stimulates microglial activity, increasing their phagocytic capability. Because microglia clear amyloid-beta aggregates, their activation leads to enhanced removal of these proteins. Therefore, phagocytosis increases, rather than inflammation dominating or plaques forming, which ultrasound doesn't directly cause.
