Discuss the anatomical basis of movement disorders
Discuss the anatomical basis of movement disorders such as Parkinson’s disease, incorporating an analysis of the dopaminergic pathways in the basal ganglia and their role in motor control. Elucidate how degeneration of dopaminergic neurons in the substantia nigra leads to characteristic symptoms such as tremors, rigidity, and bradykinesia, and explore current treatment approaches targeting dopamine replacement and deep brain stimulation.
