Awareness is a relative concept.It may refer to an internal state, such as a visceral feeling, or on external events by way of sensory perception. [2] It is analogous to sensing something, a process distinguished from observing and perceiving (which involves a basic process of acquainting with the items we perceive). [4]
Prolonged unconsciousness is understood to be a sign of a medical emergency. [3] A deficit in the level of consciousness suggests that both of the cerebral hemispheres or the reticular activating system have been injured. [4] A decreased level of consciousness correlates to increased morbidity (sickness) and mortality (death). [5]
Anosognosia is a condition in which a person with a disability is cognitively unaware of having it due to an underlying physical condition. Anosognosia results from physiological damage to brain structures, typically to the parietal lobe or a diffuse lesion on the fronto-temporal-parietal area in the right hemisphere, [1] [2] [3] and is thus a neuropsychiatric disorder.
Those with personal experience of conditions such as Depersonalisation often cite the opposite, that it is an increased awareness of the environment and the self that results in altered states of consciousness. [35] When the reduction of self-awareness and environmental awareness take effect, they produce altered states of consciousness.
Asomatognosia (also Somatoagnosia) is a neurological disorder characterized as loss of recognition or awareness of part of the body. [1] [2] The failure to acknowledge, for example, a limb, may be expressed verbally or as a pattern of neglect. The limb may also be attributed to another person, a delusion known as somatoparaphrenia. However ...

[69] [70] As implied by this definition, there are information requirements that are relevant to multiple team members. A major part of teamwork involves the area where these SA requirements overlap—the shared SA ...

Using 'awareness', however, as a definition or synonym of consciousness is not a simple matter: If awareness of the environment . . . is the criterion of consciousness, then even the protozoans are conscious. If awareness of awareness is required, then it is doubtful whether the great apes and human infants are conscious. [26]
