Bell's Palsy

Bell's palsy is the temporary paralysis of the seventh cranial nerve that causes paralysis of the face, only on the affected side. In addition, symptoms can include the inability to close the eye, pain, tearing, drooling, hypersensitivity to sound in the affected ear, and impairment of taste.

Cerebral Palsy

Cerebral palsy (seh-REE-bral PAWL-zee) (CP) is a group of disorders characterized by poor muscle control, spasticity, speech defects, and other neurologic deficiencies due to damage that affects the cerebrum. Spasticity is a condition in which certain muscles are continuously contracted. Palsy means weakness of a body part that is often accompanied by loss of feeling and uncontrolled body movements, such as shaking. -Cerebral palsy occurs most frequently in premature or low-birth-weight infants. -Cerebral palsy is usually caused by a brain injury that occurs during pregnancy, birth, or soon after birth.

Guillain-Barré Syndrome (GBS)

Guillain-Barré syndrome (gee-YAHN-bah-RAY SIN-drohm) (GBS) is an inflammation of the myelin sheath of peripheral nerves, characterized by rapidly worsening muscle weakness that can lead to temporary paralysis. This rare condition is an autoimmune reaction that can occur after certain viral infections or an immunization.

Neuritis

Neuritis (new-RYE-tis) is an inflammation of a nerve accompanied by pain and sometimes loss of function (neur means nerve, and -itis means inflammation).

Neurotomy

Neurotomy (new-ROT-oh-mee) is the surgical division or dissection (cutting) of a nerve (neur means nerve, and -otomy means a surgical incision). This procedure is used to relieve pain or suppress tremors.

Radiofrequency Ablation (RFA)

Radiofrequency ablation (RFA), also known as rhizotomy, is a minimally invasive procedure that relieves chronic nerve pain by burning part of the nerves, preventing the transmission of pain signals. RFA is often used for chronic pain and arthritis pain.

Sciatica

Sciatica (sigh-AT-ih-kah) is inflammation of the sciatic nerve caused by pressure on the nerve roots that results in pain, burning, and tingling along the course of the affected nerve through the thigh, leg, and sometimes into the foot.

Trigeminal Neuralgia

Trigeminal neuralgia (try-JEM-ih-nal new-RAL-jee-ah) is a chronic pain condition characterized by severe, lightning-like pain due to an inflammation of the fifth cranial nerve. These sudden, intense, brief attacks of sharp pain affect the cheek, lips, and gums only on the side of the face innervated by the affected nerve.
