What cranial nerves are affected in locked-in syndrome?

The corticobulbar tracts passing through the midbrain and pons contain upper motor neurons for cranial nerves 5, 7, 9, 10, 11, and 12. The pontine respiratory group located in the pons tegmentum could be affected in large lesions leading to signs of apnea and respiratory distress.

What happens in locked-in syndrome?

Although locked-in syndrome can affect anyone at any age, it is most often seen in adults that are at higher risk for brain strokes and bleeding problems. The number of those affected by locked-in syndrome is unknown, because it is rare and often either misdiagnosed or not recognized.

What are the symptoms of locked in syndrome?

Signs and symptoms. Those with locked-in syndrome may be able to communicate with others through coded messages by blinking or moving their eyes, which are often not affected by the paralysis. The symptoms are similar to those of sleep paralysis. Patients who have locked-in syndrome are conscious and aware, with no loss of cognitive function.

Can a person with locked in syndrome speak?

Locked-in syndrome is a rare neurological disorder characterized by complete paralysis of voluntary muscles, except for those that control the eyes.

What’s the difference between locked in and total locked in syndrome?

Locked-in syndrome. The individual is conscious and sufficiently intact cognitively to be able to communicate with eye movements. The EEG is normal in locked-in syndrome. Total locked-in syndrome, or completely locked-in state (CLIS), is a version of locked-in syndrome wherein the eyes are paralyzed as well.
