Not all neurological impairment requires surgery. Epilepsies, for example, are often treated with medicines in most cases. Some patients, however, may require surgical intervention to control seizures.
This is where Neurosurgery comes into play, which is a branch of medicine that surgically addresses disorders of the central and peripheral nervous system, just as Neurology treats them clinically.
If you need to, or in case of referral, seek the neurosurgeons at DaVita Serviços Médicos.
