GENETICS AND DEVELOPMENTAL DISORDERS QUESTIONS
AND ANSWERS ELABORATIONS!!
cerebral palsy (CP)
Answers:group of permanent disorders of development of movement and posture,
causing activity limitation
due to non-progressive disturbances that occured in developing infant or fetal brain
CP includes any no progressive lesions of the brain occurring prior to what age?
this results to what?
Answers:2 years of age
results in a disorder of posture and movement
etiology of cerebral palsy
Answers:- ischemic lesions in the brain
- hemorrhage around ventricles
- hypoxia causing encephalopathy and CNS malformations
- preterm infants are 30 times more likely than full term infants for developing CP
what is this describing?
, bilateral necrosis of white matter of the brain adjacent to the lateral ventricles
Answers:periventricular leukomalacia
what could cause periventricular leukomalacia?
Answers:hypoxia-ischemic injury
- systemic hypotension
-thrombi/emboli
- impaired autoregulation (ability to maintain constant perfusion)
- term infants (>37 wks): more likely due to stroke in watershed areas
classification of cerebral palsy
Answers:type of muscle tone
- dystonia: involuntary contractions causing sustained posture
- choreoathetosis: writhing movements of distal extremities
- rigidity: lead pipe, sustained resistance to movement
- spasticity: velocity dependent, catch and release phenomenon (more common)
- ataxia: movement incoordination
function - gross motor function classification system
classification of CP by topography
Answers:monoplegia - affects one limb, usually an arm
hemiplegia - affects one side of the body. including arm, leg, and trunk
