Can Bell's Palsy cause other stroke like symptoms? Such as memory lose, personality changes, chemical imbalances, or physical disablities? My son...

Bell's Palsy can cause pain, trouble speaking, and constant pain might tend to cause anger issues, but according to research, “Bells palsy should not cause any other part of the body to become paralyzed, weak or numb. If any other areas are affected Bell's palsy is not the cause of the symptoms, and further testing must be done.”
