Takeaway
Children with cerebral palsy (CP) who have normal magnetic resonance imaging (MRI) scans are more likely to have dyskinetic, ataxic/hypotonic and spastic diplegic subtypes of disease and are >5 times more likely to lack perinatal adversity.
Why this matters
MRI is a key diagnostic tool for CP even if imaging is sometimes normal; being able to associate normal imaging with specific CP subtypes can facilitate diagnosis.
