Chapter 17: Alteration in Conitive Systems, Cerebral Hemodynamics, and Motor Function COPY Flashcards
Name the three major neural systems involved in functional adequacy
Cognitive
Sensory
Motor
State of awareness of both oneself and the environment and a set of responses to that environment
Full Consciousness
State of being awake, mediated by the reticular-activating system
Arousal
Encompasses all cognitive functions and is mediated by attentional, memory, language, and executive systems
Awareness
Loss of the ability to think rapidly and clearly; impaired judgement and decision making
Confusion
Beginning loss of consciousness; disorientation time, followed by disorientation to place and impaired memory; recognition of self is lost last
Disorientation
Limited spontaneous movement or speech; easy arousal with normal speech or touch; may not be oriented to time, place, or person
Lethargy
Mild-to-moderate reduction in arousal with limited response to the environment; falls asleep unless verbally or tactilely stimulated; answers questions with minimum responses
Obtunded
Condition of deep sleep or unresponsiveness; person may be aroused or caused to open eyes only by vigorous and repeated stimulation; response is often withdrawal or grabbing at stimulus
Stupor
No verbal response to the external environment or to any stimuli; noxious stimuli such as deep pain or suctioning yields motor movement
Coma
Associated with purposeful movement on stimulation
Light coma
Associated with unresponsiveness or no response to any stimulus
Deep coma
Prolonged inspiratory and expiratory phases caused by inujury to the pons or upper medulla
Apneustic Respirations
Periods of rapid respirations of near equal depth, resulting from trauma or compression to the medulla or rom chronic opioid abuse
Cluster respirations
Irregular respirations with prolonged periods of apnea associated with damage to the medulla
Ataxic Respirations
Loss of past memories
Retrograde amnesia
Inability to form new memories
Anterograde amnesia
Loss of comprehension or production of language
Aphasia
