is caused by injury to the white matter
which occurs due to decreased oxygen or blood supply. the initial MRI may not have picked it up but it is not caused by drugs and the baby can be improved with good physiotherapy

near joints which may require surgical correction. So early intervention and treatment is the dictum.
