Overview
There are no diagnostic laboratory findings associated with cerebral palsy. The American Academy of Neurology (AAN) recommends lab studies if there is no specific structural abnormality present-, the presence of atypical features in history or physical examination and cerebral palsy associated with brain malformation. Following labs may help to rule out other diseases and may include thyroid function tests, lactate and pyruvate levels, organic and amino acids, ammonia levels and chromosomal analysis.
Laboratory Findings
- There are no diagnostic laboratory findings associated with cerebral palsy
- The American Academy of Neurology (AAN) recommends lab studies
- If there is no specific structural abnormality present-
- Presence of atypical features in history or physical examination
- Cerebral palsy associated with brain malformation
- Following labs may help to rule out other diseases
- Thyroid function tests- to rule out muscle or movement disorders
- Lactate and pyruvate levels- may show mitochondrial abnormalities
- Organic and amino acids- serum and urine levels may be deranged in inherited metabolic disorders
- Ammonia levels- elevated in liver dysfunction or urea cycle defect
- Chromosomal analysis:[1]
- Karyotype analysis
- Specific DNA testing
- Lumbar puncture:[2]
- Elevated CSF protein levels
- Low cerebrospinal fluid glucose concentration (hypoglycorrhachia)
- Diagnostic testing for coagulation disorders, if cerebral infarction is suspected
- Screening for thrombophilia[3][4]
