Cranial Nerve Disorders

Cranial nerve disorders are conditions that affect the nerves that originate in the brain, connecting to various parts of the head, neck, and face. These nerves are involved with many functions such as hearing, vision, facial expressions, and swallowing. When a cranial nerve is damaged, these functions can become impaired. Symptoms may include loss of taste or smell, double vision, hearing loss, facial weakness, or difficulty speaking. Treatment of cranial nerve disorders usually depends on the cause, but may include physical therapy, medications, or surgery. Early diagnosis and treatment are important to prevent further complications.
