Locked in syndrome and pvs essay

Recent developments in brain—computer interfaces capitalize on the neuroelec-trical properties of the brain and the localized somatic activation by these brain regions. A patient in locked-in syndrome cannot interact with us because he or she has lost the ability to control his or her body except, in most cases, the ability to move the eyes up and down but, importantly, the subliminal cues that intuitively alert us to the presence of another person are all that is needed for the suspicion to form and then the diagnosis to be confirmed by imaging and bedside interaction.

The affected person cannot communicate except by eye movements blinking, and some patients may possess vertical eye movements. The person holds it up between our eyes about mm apart. Locked-in syndrome has also been termed cerebromedullospinal disconnection, de-efferented state, pseudocoma, and ventral pontine syndrome.

Locked in syndrome, PVS and ethics at the end of life

Treatment Supportive care Supportive care is the mainstay of treatment for patients with locked-in syndrome and should include the following: We discuss the various diagnostic techniques that can be used to determine whether a patient is minimally conscious or in a persistent vegetative state.

Total locked-in syndrome occurs when the eyes are also paralyzed.

Locked-in Syndrome

They only know what they read in textbooks box 2. How could one objectively determine if these patients had an I-function? We describe a method for communication in a patient with late-stage amyotrophic lateral sclerosis ALSinvolving a fully implanted brain—com-puter interface that consists of subdural electrodes placed over the motor cortex and a transmitter placed subcutaneously in the left side of the thorax.

We discussed extensively the example of Christopher Reeve, as someone with an intact I-function, but who has lost a certain element of connectedness between total I-function control and his actual body.

Persistent Vegetative State and Minimally Conscious State

Early referral to a specialist rehabilitation service for specialist care and technology is therefore important. We systematically review and evaluate these findings in this article.

The patient's journey: Living with locked-in syndrome

All past support was immensely appreciated. When magnetic resonance imaging shows a ventral pontine insult in an otherwise unresponsive patient, the assessor should re-examine vertical eye movement.

Other complications include vertigo, insomnia, 9 and emotional lability. There are numerous grades of this syndrome, with Christopher Reeve as an example of someone who has much of his ability to communicate orally still intact. Patients retain vertical eye movement, facilitating non-verbal communication.

Because cognitive function is intact and communication is possible, patients should make their own health care decisions. Patients in the study often demonstrated complex abilities in the absence of rudimentary ones.

But Nick presents us with a different challenge.Apr 03,  · This so-called persistent vegetative state (PVS) has also been variously designated as apallic syndrome, and, most recently, unresponsive wakefulness syndrome.

Free Essay: Locked-In Syndrome and PVS: Implications for Brain = Behavior During our first few class sessions, I became very intrigued by the brain. Locked-in syndrome is a state of wakefulness and awareness with quadriplegia and paralysis of the lower cranial nerves, resulting in inability to show facial expression, move, speak, or communicate, except by coded eye movements.
