3. Flaccid Paralysis and Bulbar Palsy

Bulbar palsy affects the nerves at the base of the brain, interrupting the normal signal these nerves put out to the muscles in the face. Disruption of this signal leads to muscle weakness or paralysis and reduced muscle tone. In addition to muscle weakness, fasciculation -- small muscle contractions that cause twitching -- can also occur in the facial muscles.
