Cerebral Palsy: Clinical Case and Viva QnA

Document

Detailed Case Study of Cerebral Palsy

Patient Information

Name: Emily Thompson
Age: 4 years
Sex: Female

Chief Complaint

Parents brought Emily to the pediatric neurology clinic due to concerns about delayed motor development and difficulty walking.

History of Present Illness

Emily was born at 32 weeks gestation due to preeclampsia. Her birth weight was 1800 grams. She required mechanical ventilation for 3 days due to respiratory distress syndrome. At 2 weeks of age, she developed necrotizing enterocolitis, which was managed medically. Emily's parents noticed she was not meeting motor milestones at the expected times. She did not roll over until 9 months of age and did not sit independently until 15 months. She started crawling at 18 months but with an asymmetrical pattern, favoring her right side. At 2.5 years, she began to pull to stand but had difficulty maintaining balance. Now at 4 years, she can walk short distances with a walker but has a scissoring gait pattern.

Past Medical History

Premature birth at 32 weeks gestation
Respiratory distress syndrome
Necrotizing enterocolitis
Recurrent urinary tract infections

Developmental History

Gross motor delays as noted above. Fine motor skills are also delayed; Emily has difficulty grasping small objects and using utensils. Language development is relatively preserved, with Emily speaking in 3-4 word sentences. She demonstrates age-appropriate social skills.

Family History

No family history of neurological disorders or developmental delays.

Varieties of Presentation

Spastic Quadriplegia

A 3-year-old boy presents with severe motor impairment affecting all four limbs. He has increased muscle tone, scissoring of the legs, and clenched fists. The child cannot sit independently, has poor head control, and experiences frequent seizures. Speech is absent, and he has difficulty swallowing. MRI shows periventricular leukomalacia.

Hemiplegic Cerebral Palsy

A 2-year-old girl shows asymmetrical motor development. Her right arm and leg are weaker and stiffer than the left side. She walks with a limp, favoring her left side, and keeps her right hand fisted. Fine motor skills are impaired in the right hand. MRI reveals a focal infarct in the left middle cerebral artery territory.

Athetoid (Dyskinetic) Cerebral Palsy

A 4-year-old boy exhibits involuntary, slow, writhing movements of his arms, legs, and trunk. These movements worsen with stress and disappear during sleep. His muscle tone fluctuates between hypertonia and hypotonia. Speech is difficult to understand due to impaired control of the tongue and vocal cords. History reveals severe jaundice in the neonatal period.

Ataxic Cerebral Palsy

A 5-year-old girl presents with difficulties in balance and coordination. She has a wide-based, unsteady gait and intention tremor when reaching for objects. Her speech is slow and halting. Fine motor skills are poor, affecting handwriting and self-care activities. MRI shows cerebellar hypoplasia.

Mixed Cerebral Palsy (Spastic-Dystonic)

A 6-year-old boy shows features of both spasticity and dystonia. He has increased muscle tone in his legs with scissoring gait, but also experiences intermittent, twisting postures of his trunk and arms, particularly when attempting voluntary movements. Cognitive function is moderately impaired, and he has strabismus. MRI reveals basal ganglia injury and periventricular white matter damage.

Viva QnA

1. What is the definition of Cerebral Palsy?

Cerebral Palsy (CP) is a group of permanent disorders affecting 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. The motor disorders of CP are often accompanied by disturbances of sensation, perception, cognition, communication, and behavior, by epilepsy, and by secondary musculoskeletal problems.

2. What are the main types of Cerebral Palsy based on motor impairment?

The main types of Cerebral Palsy based on motor impairment are:

Spastic CP (most common, about 70-80% of cases)
Dyskinetic CP (including choreoathetoid and dystonic subtypes)
Ataxic CP
Mixed CP (combinations of the above types)

3. What are the risk factors for developing Cerebral Palsy?

Risk factors for Cerebral Palsy include:

Prematurity and low birth weight
Multiple gestation (twins, triplets)
Intrauterine infections (TORCH infections)
Maternal infections during pregnancy
