The locked-in syndrome is caused by an insult to the ventral pons, most commonly an infarct, haemorrhage, or trauma. The characteristics of the syndrome are quadriplegia and anarthria with preservation of consciousness. Patients retain vertical eye movement, facilitating non-verbal communication. Ten year survival rates as high as 80% have been reported. Even limited physical recovery can improve quality of life and enable patients to return to live with their families. Early referral to a specialist rehabilitation service for specialist care and technology is therefore important.
