What Is The Difference Between A Coma And A Persistent Vegetative State?

Is vegetative state worse than coma?

In a vegetative state the person is still unconscious.

They have no awareness of themselves or their environment.

The main difference between ‘coma’ and the ‘vegetative state’ is that at some point the person’s eyes will be open and there will be times when they seem to be ‘awake’..

How is persistent vegetative state diagnosed?

The clinical criteria are: No evidence of awareness of self or environment; no interaction with others. No evidence of sustained, reproducible, purposeful or voluntary behavioral responses to visual, auditory, tactile or noxious stimuli. No evidence of language comprehension or expression.

What is the difference between brain death and persistent vegetative state?

Intensive medical support is usually withdrawn. In contrast, the diagnosis of brain death depends on death of the brainstem, while PVS implies permanent and total loss of forebrain function. While brainstem death can be diagnosed clinically, accurate prognosis in PVS requires additional investigation.

What is the longest someone has been in a vegetative state?

Elaine Esposito (December 3, 1934 – November 25, 1978) held the record for the longest period of time in a coma according to Guinness World Records, having lost consciousness in 1941 and eventually dying in that condition more than 37 years later.

Has anyone ever recovered from a vegetative state?

About 50% of persons who are in a vegetative state one month after traumatic brain injury eventually recover consciousness. They are likely to have a slow course of recovery and usually have some ongoing cognitive and physical impairments and disabilities.

Can someone hear you if they are in a vegetative state?

Other studies have shown that up to 20 percent of patients in various vegetative states can hear and respond on at least some level. But at least some of the responses seen could be dismissed as simple reflexes, or at best akin to someone in a dream state responding to stimuli.

Can the brain heal after lack of oxygen?

A full recovery from severe anoxic or hypoxic brain injury is rare, but many patients with mild anoxic or hypoxic brain injuries are capable of making a full or partial recovery. Furthermore, symptoms and effects of the injury are dependent on the area(s) of the brain that was affected by the lack of oxygen.

Can you feel pain in a vegetative state?

IT IS a nightmare situation. A person diagnosed as being in a vegetative state has an operation without anaesthetic because they cannot feel pain.

Can you pull the plug on someone in a vegetative state?

This means the patient would be unable to cough or swallow or breathe on her own, whereas a patient in a vegetative state may be able to do one or all of those three things, DiGeorgia said. … “Pulling the plug” would render the patient unable to breathe, and the heart would stop beating within minutes, he said.

How long can someone be in a coma and still wake up?

Recovering from a coma A coma usually only lasts a few weeks, during which time the person may start to gradually wake up and gain consciousness, or progress into a different state of unconsciousness called a vegetative state or minimally conscious state.

What are the chances of coming out of a vegetative state?

Generally, adults have about a 50 percent chance and children a 60 percent chance of recovering consciousness from VS/UWS within the first 6 months in the case of traumatic brain injury. For non-traumatic injuries such as strokes, the recovery rate falls within the first year.

What does it mean to be in a persistent vegetative state?

The term “persistent vegetative state” was coined by Jennett and Plum in 1972 to describe the condition of patients with severe brain damage in whom coma has progressed to a state of wakefulness without detectable awareness1. Such patients have sleep-wake cycles but no ascertainable cerebral cortical function.

What part of the brain is damaged in a coma?

Comas are caused by damage to the brain, specifically the diffused bilateral cerebral hemisphere cortexor the reticular activating system. This area of the brain controls arousal and awareness.

How long can a person stay in a vegetative state?

Rarely, improvement occurs late. After 5 years, about 3% of people recover the ability to communicate and understand, but few can live independently, and none can function normally. Most people who remain in a vegetative state die within 6 months of the original brain damage. Most of the others live about 2 to 5 years.

Why do coma patients cry?

A comatose patient may open his eyes, move and even cry while still remaining unconscious. His brain-stem reflexes are attached to a nonfunctioning cortex. Reflex without reflection. Many professionals speak of this condition as a ”persistent vegetative state.
