Condition causing facial weakness

Facial weakness may be the sign of a stroke or bell's palsy & requires immediate medical attention.

Rarity: Uncommon

Top Symptoms: face weakness

Urgency: Hospital emergency room

Bell's palsy

Bell’s palsy can present as acute or chronic facial paralysis. This paralysis is usually sudden in onset and worsens over the course of 48 hours. Resolution of symptoms usually occurs within two weeks to six months but permanent paralysis can rarely occur. Symptoms of this condition are a result of the paralysis of facial muscles. This paralysis usually occurs only on one side of the face. The cause of Bell’s palsy is inflammation or damage to the facial nerve, also known as cranial nerve VII. This nerve controls the muscles of the face. Treatment is aimed at reducing inflammation or targeting the underlying cause of facial nerve paralysis.

Stroke or tia (transient ischemic attack)

Transient ischemic attack, or TIA, is sometimes called a "mini stroke" or a "warning stroke." Any stroke means that blood flow somewhere in the brain has been blocked by a clot.

Risk factors include smoking, obesity, and cardiovascular disease, though anyone can experience a TIA.

Symptoms are "transient," meaning they come and go within minutes because the clot dissolves or moves on its own. Stroke symptoms include weakness, numbness, and paralysis on one side of the face and/or body; slurred speech; abnormal vision; and sudden, severe headache.

A TIA does not cause permanent damage because it is over quickly. However, the patient must get treatment because a TIA is a warning that a more damaging stroke is likely to occur. Take the patient to the emergency room or call 9-1-1.

Diagnosis is made through patient history; physical examination; CT scan or MRI; and electrocardiogram.

Treatment includes anticoagulant medication to prevent further clots. Surgery to clear some of the arteries may also be recommended.

Rarity: Common

Top Symptoms: dizziness, leg numbness, arm numbness, new headache, stiff neck

Symptoms that never occur with stroke or tia (transient ischemic attack): bilateral weakness

Urgency: Emergency medical service

There are five main types of head and neck cancer, which are all named according to the part of the body where they develop: laryngeal (voice box), nasal cavity and sinus, nasopharyngeal (air passage way behind the nose), oral (mouth), and salivary gland cancers. Most of these cancers are squamous cell carcinomas (SCCs), meaning they begin in the flat (squamous) cells that make up the thin surface layer of the structures in the head and neck.
