Leading cause of childhood disability effecting function and development.
Defined as a group of disorders involving motor or postural abnormalities that are noted during early development
Injury occurs during fetal or neonatal period up to 3 yrs. Official diagnosis may not be made until 3 years of age
Associated with
Birth: hypoxia, placental abruption, prolonged labor, uterine rupture
Child: jaundice/kernicterus, low-birth weight, prematurity
Mother: infection (prenatal), infertility treatment, multiple births, thyroid disorder, seizure disorder

Spastic<unk>  is the most common type, ~80% of cases
Spastic diplegia (30-40%)
Bilateral lower extremities effected more than upper extremities or sole involvement of lower extremities.
Spastic hemiplegia (20-30%)
One side of the body effected, including an upper and lower extremity
Upper extremity spasticity effected more than lower extremity
Double hemiplegia: when both arms are more involved than the legs
Double hemiplegia: when both arms are more involved than the legs
Spastic quadriplegia (10-15%)<unk>  affecting all 4 extremities and the trunk (full body)
Dyskinetic<unk> 
Athetoid, choreoathetoid, and dystonic
Extrapyramidal signs characterized by abnormal movements; hypertonicity
Mixed<unk> 
Mixture of spastic and dyskinetic components without predominant area
Hypotonic<unk> 
Rare: Truncal and extremity hypotonia with hyperreflexia and persistent primitive reflexes
Monoplegia
Rare: One limb involved, either an arm or a leg
Must rule out other causes.
Cerebral palsy
Neuromuscular weakness
Hydrocephalus
UMN:
Vaughn Jackson syndrome
CVA 
Brachial plexus injury
Hemorrhagic stroke
