As a result of a severe head injury, for example an injury sustained during a car accident, a fall from a great height, or a violent assault, a person can enter into a state of vegetative consciousness. According to Gosseries et al. (2011), in most cases where the damage is severe, patients usually die within a few days. If they do survive however, from the moment the patients open their eyes, they move out of a coma and, if still unresponsive, evolve into a vegetative state. Typically, the vegetative patient gradually recovers awareness and enters a minimally conscious state. This is often followed by a period of transient

Examples of these conditions are in instances where the brain is deprived of oxygen in which cases brain tissue begins to die. It can also be a condition in which the brain tissue is directly attacked. Specific examples would include a stroke, heart attack, drug overdose or severe brain infections such as meningitis, just to mention a few. Finally, the vegetative state can be a as a result of progressive brain damage. This is a situation where the brain gets damaged gradually as a result of diseases such as Alzheimer’s, Parkinson’s disease or a brain tumour and eventually leads to the individual going into a vegetative state (Gosseries et al, 2011).
