Q

Myelomeningocele

A

35
Q

Bacterial meningitis

A
  • Most potentially serious infections occurring in infants & older children

40
Q

Cerebral Palsy

A

A group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain.

Q

Seizure Disorders

A
  • Time-limited change in motor activity and/or behavior that results from abnormal electrical discharge from neurons in the cerebral cortex.

  • Neuromuscular degenerative disorders
  • Head trauma
54
Q

Seizure disorders- originating outside the brain

A
  • Fever
