In most cases, those who receive a locked-in syndrome diagnosis retain full cognitive functioning. Locked-in syndrome occurs because of a stroke or other issues in the brain stem. This is separate from the parts of the brain that control cognitive functions.
When there is a change in cognitive function following an acute brain injury and locked in diagnosis, there was likely damage to other parts of the brain that caused it.
What Is Locked-In Syndrome?
Locked-in syndrome is a condition that may occur following a hemorrhage or blockage in the blood vessels that feed the brain stem and the pons. It is very rare and often misdiagnosed. Patients with locked-in syndrome are awake and aware but suffer from quadriplegia and paralysis. That person cannot move, speak, or communicate without assistance. He or she remains conscious with full cognitive functioning.
There are three types of locked-in syndrome:
Classic Locked-In Syndrome
Classic locked-in syndrome is characterized by global paralysis except for vertical eye movements and sometimes blinking.
Total Locked-In Syndrome
Total locked-in syndrome occurs when patients suffer global paralysis without any exception – the patient cannot move any part of their body voluntarily, including vertical eye movements.
Incomplete Locked-In Syndrome
In cases of incomplete locked-in syndrome, all the symptoms of a classic locked-in syndrome are present expect the patient retains voluntary motor function in additional parts of the body.
Other Types of Brain Injury May Explain Any Decrease in Cognitive Function
One 2008 study that evaluated ten patients with locked-in syndrome confirmed most patients retained full cognitive functions. The functions tested included:
- Short-term memory
- Long–term memory
- Attention span
- Executive functioning
- Phonological and semantic processing
- Verbal intelligence
Most people retained normal cognitive functions despite their locked in syndrome diagnosis. Researchers felt that those who did not likely suffered additional brain injuries, with lesions on other areas of the brain. It is likely these injuries — and not the injury to the brain stem that caused locked in syndrome — are responsible for any problems with cognitive functions.
Cognitive Function Contributes to a Relatively High Quality of Life
Patients with locked-in syndrome report a relatively high quality of life and many of them can live at home with ongoing support from caregivers. Intact cognitive functioning plays a key role in the quality of life, allowing the patient to live a full life without being able to ambulate on their own.
People with locked-in syndrome have written books, served as professors, and even consulted on legal cases. While most never return to work, these people can often find tasks that contribute to the world around them. The Internet and other technological advances make this even easier.
Cognitive Function Allows for Communication with the Outside World
When locked in syndrome was first named in the 1960s, patients could only communicate through blinking their eyes or utilizing vertical eye movements. Their family or caregivers would come up with a code for yes and no and would use an alphabet board to spell words. This is how journalist Jean-Dominique Bauby penned his memoir about living with locked-in syndrome, The Diving Bell and the Butterfly. Without cognitive functioning, spelling words and communicating using code would not be possible.
Today, technology plays a crucial role in helping those with locked-in syndrome communicate with their doctors, family members, and the outside world. Eye gaze devices and brain/computer interfaces, among others, improve the quality of life for these patients.
