Unfortunately, while it is known that the facial nerves are affected, the exact cause is unknown. Oftentimes, a viral infection can trigger Bell’s palsy after it becomes dormant and reactivates. Other factors such as weakened immunity, prolonged stress, inadequate sleep, and autoimmune disorders can contribute to Bell’s palsy.
To reduce swelling and inflammation of the facial nerves, doctors will prescribe medications called steroids. Treatment is most effective within 72 hours of the onset of symptoms. Even without treatment, Bell’s palsy can resolve on its own in about 3 weeks. However, there may be long-lasting weakness or some degree of paralysis if treatment is delayed.
What is Stroke?
Stroke is a term used to describe a condition wherein part of the brain is deprived of oxygen or nutrients. Clots or cholesterol plaques from other parts of the body can travel through the bloodstream and get stuck in arteries in the brain.
When this happens, the blockage stops blood flow and the affected areas of the brain begin to deteriorate. A “mini stroke” or transient ischemic attack is a temporary blockage that is less likely to cause permanent damage. Alternatively, head trauma or broken vessels can result in uncontrolled bleeding or hemorrhage, which can also cause a stroke.
