What are neurologic conditions?

Neurologic conditions affect the nervous system, which is responsible for regulating and coordinating bodily functions. The nervous system has two major divisions, the central nervous system and the peripheral nervous system.

Some of the more common neurologic conditions are:

  • neurodegenerative disorders like Alzheimer’s disease, Parkinson’s disease and amyotrophic lateral sclerosis (ALS)
  • concussions
  • epilepsy
  • migraine and other headache disorders
  • multiple sclerosis and other demyelinating diseases
  • stroke

How do neurologists treat patients?

According to the Cleveland Clinic, neurologists may use a host of diagnostic approaches such as blood, urine or other fluid tests in order to help understand a condition’s severity or check on medication levels. Additionally, neurologists may use genetic testing to identify inherited disorders.

Imaging studies of a patient’s nervous system might also be ordered to aid in diagnosis. Once a diagnosis is made, neurologists use medications, physical therapy or other approaches.

Neurologists do not perform surgery. If one of their patients requires surgery, they refer them to a neurosurgeon.
