Moebius syndrome is a rare neurological disorder that is present at birth. People with the condition are unable to move their faces (they can't smile, frown, suck, grimace or blink their eyes) and are unable to move their eyes from side to side. There may be skeletal problems as well, causing hand/feet anomalies such as club feet. Respiratory problems, speech and swallowing disorders, visual impairments, sensory processing disorder, sleep disorders, and weak upper body strength may also be present. Approximately 30% of children with Moebius syndrome are on the autism spectrum.
