Exam 3 Flashcards
4 Causes of Brain Damage
- stroke
- head injury
- tumors
- progressive degeneration of the central nervous system
types of strokes
o Embolism
o Thrombosis
o Hemorrhage
o Aneurysm
o TIA – Transient Ischemic Attack
Alzheimer’s disease is caused by
- Degeneration of neurons
- Accumulation of amyloid plaques
- Tangles of strands of protein
two types of head injuries
penetrating injury
closed head injury
4 things tumors do:
- Take up space
- destroys brain tissue
- create edema
- increased pressure in the skull
Progressive degeneration of brain functions
alzheimers disease
frontotemporal dementia
huntingtons disease and parkinsons disease
a moving clot from another part of the body that lodges in the artery,
embolus
occurs when an artery has gradually filled in with plaque.
Thrombosis
a weakening in the artery that bulges and eventually breaks, interrupting blood flow to tissues fed by the artery.
aneurysm
involve bleeding in the brain.
hemorrhage
temporary closing of the artery with symptoms that disappear within 24 hours.
TIA transient ischemic attack
deprivation of oxygen or lack of oxygen to the brain
anoxia
tissue death
Infarct
tissue swelling
Edema
a recovery of function ability goes up, and the patient spontaneously recovers.
Spontaneous Recovery
a foreign object enters into the skull and can cause damage to the brain. tears the skin, breaks the skull, goes into the brain
Penetrating injuries
not penetrating, skull is still intact. Whole brain shakes up (whiplash) brain is twisting
Closed head injury
a bruise on the cortex or surface of the brain
contusion
tearing of structures or blood vessels
lacerations
inside the brain damage to the nerve cells and fibers of the brain
Intracerebral damage
layers that help to protect the brain
Meninges
area of encapsulated blood pocket of blood that forms and pushes on the brain
Hematomas
Additional information about head injuries
head injury can be from mild to severe, more severe the brain injury is, the more problems they will have.
Tumors are also called
neoplasms or new growth
New growth that happens in the brain or other structures. space occupying legion- something occupying space in the brain. Can be cancerous or not.
tumors
of patients that have dementia, _____of them have Alzheimer’s disease.
70%
what happens during Alzheimer’s disease
Sulci in the brain become wider and brain starts to deteriorate (supposed to be compressed and closer together) lose neurons as they start to die. Tangles form in the brain. accumulation of amyloid plaques
frontal and temporal areas are the parts that start to degenerate first. Pick body starts to eat away at the brain.
Frontotemporal dementia (Pick’s disease)
Huntington’s disease and Parkinson’s disease
degeneration basal ganglia
A patient will have problems with motor movement because it is degeneration of the basil ganglia
Huntington’s disease and Parkinson’s disease
in charge of motor movement.
basil ganglia
Huntington’s disease can be inherited, there is a _____ chance a child may get it
50%
a language disorder caused by left hemisphere damage, typically resulting from a stroke.
aphasia
common characteristics of the aphasia
Auditory comprehension, verbal expression, and reading and writing deficits, naming problems
