DHYG Exam III Questions and Verified Answers
What are the neurological conditions and disorders?
-neurological: epilepsy/seizures, CVA
-developmental: autism
-genetic: down syndrome
-degenerative: MS, alzheimers disease, parkinsons disease
two types of stroke:
-ischemic: blood clot blocks blood flow
-hemorrhagic: BV bursts
what is a CVA? (neurological)
-sudden interruption of oxygenated blood to brain cause tissue necrosis
-the clinical manifestation of CVA
-Effects motor, speech, and some cognitive dysfunction
what is the greatest risk/predisposing factor to CVA?
hypertension
what are other predisposing CVA?
-arteriosclerosis
-high cholesterol, high glycemia
-tobaccos use
-cardiovascular disease
-diabetes
,-oral contraceptive
- drug abuse
what are the four etiologies of CVA? most common?
-thrombosis: most common; blood clot that occludes blood supply leading infarction
-intracerebral embolism
-ischemia (TIA): decreased blood flow
-cerebral hemorrhage: rupture and bleeding of BV into brain tissues
what is intracerebral embolism?
BV blocked by clot or material carried thru circulation from another part of the body
-artherosclerotic plaque buildup (artheroma) causes embolus which raises CVA risk
What is the BEFAST acronym?
stroke warning signs
B For a loss of balance, Eyes for blurred vision, Face for facial drooping, Arms for arm/leg
weakness,
Speech for speech difficulty,
Time for time to call ambulance
what are the residual and chronic symptoms of CVA?
Temporary or permanent loss of thought, memory, speech, sensation, and motion
-the side of brain affected influences the symptoms
-the side of face and body affected is the opposite of brain injury
, what are the symptoms of right hemiplegia?
-more diff with verbal communication
-being cautious, anxious, or disorganized
what are the symptoms of left hemiplegia?
-more diff w physical coordination
-overconfidence
what are the post-stroke symptoms?
Physical paralysis
salivation and swallowing difficulty
increased pain/touch sensitivity
visual impairment
mental dysfunction possible
personality changes
aphasia (loss of speech ability)
med management for CVA:
Drugs: anticoagulant, antihypertensive, thrombolytic, vasodilator, steriod, antiepileptic
Surgical: correction of aneurysms/clots/malformations, removal of small clots, grafting to
bypass blocked vessels
Therapy: physical, occupational, and speech therapy
dental management of CVA:
-timing: don't treat if within last 6mon (high reoccurrence chance)
-what are they doing med manage? (anticoagulant/INR)
-identify risk factors: what conditions? rad therapy up artherosclerosis
