Nervous Flashcards
Cerebrovascular accident (stroke)
Brain is damaged by a sudden disruption in the flow of blood to a part of the brain {embolic} or by bleeding inside the head{hemorraghic}
Aphasia
Disturbance in language comprehension or production, often as a result of a stroke
Dysphasia
Difficult speech
Paralysis
Absence of strength secondary to nervous impairment
Hemiparesis
Partial paralysis of the right or left half of the body
Diplopia
Double vision
Transient Ischemic Attack (mini-stroke)
temporary episodes with a duration of less than 24 hours of impaired neurologic functioning caused by an inadequate flow of blood to a portion of the brain
Ulcer
A deep loss of skin surface that may extend into the dermis; may cause periodic bleeding and the formation of scars.
Concussion
A loss of function, either partial or complete, as resulting from a blow or fall (for instance)
Contusion
A bruise
Contrecoup
also known as a counter blow, is an injury that occurs beneath the skull opposite to the area of impact
Epidural hematoma
Collection of blood that forms between the skull and the dura mater
Dura mater
Outermost layer of the meninges
Subdural hematoma
blood collects btween the dura mater and the arachnoid membrane
Arachnoid membrane
Middle layer of the three membranes (meninges) that surround the brain and spinal cord
Craniotomy
Incision into the skill
Cerebral concussion
Temporary brain dysfunction (brief loss of consciousness) after injury, usually clearing within 24 hours
Cerebral contusion
Bruising of brain tissue as a result of direct trauma to the head; neurologic deficits persist longer than 24 hours
Depressed skull fracture
-bone pressed inward into the brain tissue to at least the thickness of the skull; skull depressed : may cause bruising or tearing of dura and lead to menengitis or seizures, -skull depressed : may cause bruising or tearing of dura and lead to menengitis or seizure
Hemiplegia
Paralysis of one side of the body
Battle’s signs
Bruising behind the ears (over the mastoid process); a very late sign of skull fracture.
Raccoon eyes
Basal skull fracture
