CP and LD (Week 9) Flashcards
Group of permanent or chronic neurological disorder, affecting movement, balance and posture
Cerebral palsy
When does CP occur?
fetal period, during birth, or in early infancy but not diagnosed until later
4 topographical classification of CP
- Monoplegia/ Monoparesis
- Diplegia/ Diparesis
- Hemiplegia/ Hemiparesis
- Quadriplegia/ Quadriparesis
2 Motor function classification of CP
- Pyramidal
2. Extrapyramidal
Extrapyramidal is broken into what 2 categories
- Dyskinetic
2. Ataxia
If injury to pyramidal area what type of mvmt is affected?
voluntary
If injury to extrapyramidal area what type of mvmt is affected?
involuntary mvmt bc areas like basal ganglia, thalamus, cerebellum are affected
Most common type of CP (3)
- spastic CP (pyramidal)
o 1. Hemiplegia
o 2. Diplegia
o 3. Quadriplegia
Type of dyskinetic CP with symptoms:
Writhing mvmts, repetitive, rhythmic, slower
Athetoid
Type of dyskinetic CP with symptoms:
Jerky almost like a spasm
Chorea
Type of dyskinetic CP with symptoms:
- Sustained posture esp. in trunk
- move, fix, and then come out of the mvmt
Dystonic
Type of dyskinetic CP seen along w/spastic quadriplegia frequently
Dystonic
What is chorea commonly seen with?
chorea athetosis
CP that affects balance and coordination
Ataxic CP
9 risk factors for CP
- Prematurity & SGA
- Multiples
- Prenatal infections: CMV, toxoplasmosis, rubella
- Rh disease
- Challenging labor
- Placental inefficiencies
- Brain infections (post birth)
- Toxin exposure: mercury
- Brain injury
3 complications that put baby at higher risk of getting CP
1. Interventricular Hemorrhage (IVH)
2. Hypoxic-Ischemic Encephalopathy (HIE)
3. Periventricular Leukomalacia (PVL)
Bleeding into the ventricular space within the brain hemispheres
Interventricular Hemorrhage (IVH)
Risk factors for IVH (3)
o prematurity, SGA,
o respiratory distress syndrome
o patent ductus arteriosus (PDA)
When can IVH occur?
in-utero or after they are born esp. premies
What grade of IVH is when bleeding expands beyond germinal matrix into the ventricular system?
Grade II
What occurs during Grade III IVH?
Bleeding dilates the ventricles and they are pushing on other brain tissue
What % of Grade III IVH get CP?
30%
What grade of IVH has periventricular Hemorrhagic Infarction (PHL-IVH) in addition to IVH?
Grade IV
Describe Grade I IVH?
Bleeding into a network of blood vessels in the roof of the lateral ventricles (isolated to germinal matrix)
What % of Grade IV IVH get CP?
75%
