Which motor disorder is caused by brain injury or abnormal brain growth and is characterized by coordination problems?

• A. Epilepsy
• B. Muscular Dystrophy
• C. Multiple Sclerosis
• D. Cerebral Palsy

Answer: (D)

Cerebral palsy is a group of permanent movement and posture disorders that arise from disturbances in the developing brain, either from brain injury or abnormal brain growth during fetal development or early infancy. The defining feature is impaired movement coordination and motor control, which can show up as stiffness (spasticity), involuntary movements (dyskinesia), or problems with balance and coordination (ataxia). Because the issue is in the brain, CP affects how the body moves rather than the muscles themselves becoming diseased. Epilepsy involves recurrent seizures from abnormal brain electrical activity, not a primary coordination disorder. Muscular dystrophy is a muscle-weakening condition caused by genetic issues in the muscles themselves, not a brain injury. Multiple sclerosis is an autoimmune disease that damages the myelin in the central nervous system, typically in adults, with a broader mix of neurological symptoms rather than a primary early-brain-injury–driven coordination problem. So, the description—motor disorder caused by brain injury or abnormal brain growth with coordination problems—best fits cerebral palsy.
