Neurological Assessment Flashcards
(39 cards)
Abstract Reasoning
involves flexible thinking, creativity, judgment, and logical problem solving
Agnosia
inability to interpret sensations and hence to recognize things, typically as a result of brain damage
Agraphia
a cerebral disorder characterized by total or partial inability to write
Analgesia
the inability to feel pain
Apraxia
inability to perform particular purposive actions, as a result of brain damage
Ataxia
the loss of full control of bodily movements
Attention
the ability to focus selectively on a selected stimulus, sustaining that focus and shifting it at will. The ability to concentrate.
Coma
a state of deep unconsciousness that lasts for a prolonged or indefinite period, caused especially by severe injury or illness
Consciousness
the state of being awake and aware of one’s surroundings
Conjugate Gaze
the motion of both eyes in the same direction at the same time, and conjugate gaze palsy refers to an impairment of this function
Corneal Reflex
an involuntary blinking of the eyelids elicited by stimulation of the cornea (such as by touching or by a foreign body), or bright light, though could result from any peripheral stimulus
Decerebrate Rigidity
a postural change that occurs in some comatose patients, consisting of episodes of opisthotonos, rigid extension of the limbs, internal rotation of the upper extremities, and marked plantar flexion of the feet; produced by a variety of metabolic and structural brain disorders
Decorticate Rigidity
a unilateral or bilateral postural change, consisting of the upper extremities flexed and adducted and the lower extremities in rigid extension; due to structural lesions of the thalamus, internal capsule, or cerebral white matter
Dermatome
the lateral wall of each somite in a vertebrate embryo, giving rise to the connective tissue of the skin
Dysarthria
difficult or unclear articulation of speech that is otherwise linguistically normal
Dysphonia
difficulty in speaking due to a physical disorder of the mouth, tongue, throat, or vocal cords
Fasciculation
a brief, spontaneous contraction affecting a small number of muscle fibers, often causing a flicker of movement under the skin. It can be a symptom of disease of the motor neurons
Graphesthesia
the ability to recognize writing on the skin purely by the sensation of touch
Hemianopsia
blindness over half the field of vision
Hemiplegia
paralysis of one side of the body
Lower Motor Neuron
a motor neuron whose cell body is located in the brainstem or the spinal cord and whose axons innervate skeletal muscle fibers
Myoclonus
spasmodic jerky contraction of groups of muscles
Nuchal Rigidity
impaired neck flexion resulting from muscle spasm (not actual rigidity) of the extensor muscles of the neck; usually attributed to meningeal irritation
Orientation
awareness of one’s environment with reference to time, place, and people
