A confused person may be bewildered, disoriented, and have difficulty following instructions. People who do not respond quickly with information about their name, location, and the time are considered "obtuse" or " confused".
ĭisoriented impaired thinking and responses "Clouding of consciousness" is a term for a mild alteration of consciousness with alterations in attention and wakefulness. A normal sleep stage from which a person is easily awakened is also considered a normal level of consciousness. Īssessment of LOC involves checking orientation: people who are able promptly and spontaneously to state their name, location, and the date or time are said to be oriented to self, place, and time, or "oriented X3". In the field of cognitive neuroscience, metacognitive monitoring and control have been viewed as functions of the prefrontal cortex, which receives sensory input signals from divergent cortical regions and implements control through feedback loops which are established utilizing the underlying mechanisms of neuroplasticity (see chapters by Schwartz & Bacon and Shimamura, in Dunlosky & Bjork, 2008). People who possess the ability to monitor and control their own cognitive processes in addition to meeting all the criteria indicative of a normal level of consciousness. Scales and terms to classify the levels of consciousness differ, but in general, reduction in response to stimuli indicates an altered level of consciousness: In fact, some sources consider level of consciousness to be one of the vital signs. Thus it is a valuable measure of a patient's medical and neurological status. A decreased level of consciousness correlates to increased morbidity (sickness) and mortality (death). A deficit in the level of consciousness suggests that both of the cerebral hemispheres or the reticular activating system have been injured.
Prolonged unconsciousness is understood to be a sign of a medical emergency.
exposure to poisons or intoxicants), insufficient oxygen or blood flow in the brain, and excessive pressure within the skull. Scales such as the Glasgow coma scale have been designed to measure the level of consciousness.Īn altered level of consciousness can result from a variety of factors, including alterations in the chemical environment of the brain (e.g. Coma is the inability to make any purposeful response. Those who are not able to be aroused from a sleep-like state are said to be stuporous. People who are obtunded have a more depressed level of consciousness and cannot be fully aroused. A mildly depressed level of consciousness or alertness may be classed as lethargy someone in this state can be aroused with little difficulty. Level of consciousness ( LOC) is a measurement of a person's arousability and responsiveness to stimuli from the environment. Medical condition Altered level of consciousnessĪn intracranial hemorrhage, one cause of altered level of consciousnessĪn altered level of consciousness is any measure of arousal other than normal.
