Final answer:
Pallidotomy is indicated for Parkinson's disease to alleviate symptoms and improve motor function.
Step-by-step explanation:
Parkinson's disease is a degenerative disorder of the central nervous system that mainly affects the muscular system and movement. It causes the loss of dopamine neurons in the midbrain, resulting in symptoms such as tremor, rigidity, slowness of movement, and postural instability. Pallidotomy, which is the surgical destruction of a small part of the brain called the globus pallidus, is indicated as a treatment for Parkinson's disease to alleviate symptoms and improve motor function.
