Study Notes

Definition and Nature of Cerebral Palsy

Cerebral palsy is a neurodevelopmental disorder characterized by upper motor neuron lesions.
The condition is non-progressive, meaning the damage does not worsen over time.

Etiology

Multifactorial causes linked to prenatal development, birthing process, and postnatal period.
Premature births are the most common cause, potentially leading to periventricular leukomalacia (PVL).
PVL occurs due to inadequate blood supply to the developing brain, affecting white matter and upper motor neuron tracks.
Isolated intraventricular hemorrhage can impact premature infants due to fragile capillaries near the ventricles.

Intrauterine Infections

Intrauterine infections may contribute to cerebral palsy, summarized by the mnemonic "TORCH":
- Toxoplasmosis
- Rubella
- Cytomegalovirus
- Herpes simplex virus
- Other (includes syphilis, Zika, varicella zoster).

Hypoxic and Ischemic Insults

Hypoxia or ischemia in the fetal brain can be caused by placental issues (e.g., abruption, previa) impacting oxygen transfer.
Umbilical cord compression during birth may also lead to oxygen deprivation.

Postnatal Factors

After birth, cerebral palsy can result from intracerebral hemorrhage or trauma.
Infections such as meningitis or encephalitis can cause damage to the brain.
Kernicterus, resulting from excessive unconjugated bilirubin due to hemolysis, can lead to brain injury.

Genetic Factors

Genetic susceptibility may play a role, with associations found in mutations affecting glutamate decarboxylase.

Classification of Cerebral Palsy

Cerebral palsy can be classified into several types:
- Spastic (common): Characterized by hyperreflexia, clonus, spasticity, weakness, and pathological reflexes.
- Dyskinetic: Involves basal ganglia injury leading to unwanted movements (chorea, athetosis), rigidity, and dystonia.
- Ataxic: Injury to the cerebellum affecting balance and coordination.
- Mixed: Combination of the aforementioned types.

Upper Motor Neuron Lesion Characteristics

Classical signs include:
- Increased deep tendon reflexes (hyperreflexia)
- Clonus
- Increased muscle tone (spasticity)
- Possible weakness
- Pathological reflexes (e.g., Babinski sign).

Specific Forms of Cerebral Palsy

Hemiplegic CP: Affects one side of the body (contralateral side weakness).
Diplegic CP: Primarily affects lower extremities more than upper, with some upper extremity involvement.
Quadriplegic CP: Affects all four limbs, bilaterally impacting upper and lower extremities.

Dyskinetic Cerebral Palsy

Lesions in the basal ganglia disrupt the inhibition of unwanted movements, leading to:
- Chorea: Jerky movements.
- Athetosis: Snake-like, writhing movements of hands.
- Dystonia: Sustained involuntary muscle contractions.

Ataxic Cerebral Palsy

Resulting from injuries to the cerebellum, affecting motor coordination and balance, leading to gait and movement difficulties.### Cerebellum and Cerebral Palsy
Tone, balance, and coordination are crucial functions of the cerebellum.
Injury to the cerebellum results in hypotonia, characterized by floppy muscles and compromised balance.
Ataxia may develop, leading to a wide-based gait and frequent stumbling.
Coordination issues manifest as dysdiadochokinesis (altered rapid movements) and dysmetria (inaccuracy in movement).

Complications Associated with Cerebral Palsy

Cognitive and intellectual disabilities can arise due to inadequate brain development.
Seizures are a common complication linked with cortical neuron involvement.
Visual problems may include strabismus, amblyopia, and visual refractive errors, affecting eye muscle coordination.
Hearing impairment may occur due to inner ear structure issues.
Neuromuscular scoliosis can develop from muscle imbalances leading to spinal curvature abnormalities.
Higher adductor tone can result in a scissoring gait and may lead to hip dislocation or subluxation.
Speech difficulties often manifest as dysarthria, while dysphagia (difficulty swallowing) is also common.
Pseudobulbar palsy can develop, affecting muscles for speech and swallowing due to upper motor neuron damage.
Cialorrhea (excessive salivation) often occurs due to impaired secretion control.
Gastrointestinal issues such as gastroparesis and constipation may arise from decreased GI tract tone.
Aspiration pneumonia risk is heightened due to swallowing difficulties and poor secretion control.
Scoliosis can also affect thoracic structures, leading to hypoventilation syndromes akin to restrictive lung disease.
Spasticity leads to pain, muscle weakness, and joint contractures over time.

Treatment Approaches

There is no cure for cerebral palsy; treatment focuses on managing various complications, requiring a multidisciplinary team including physical, occupational, and speech therapists.
Medical management primarily targets spasticity using both central and peripheral medications:
- Central: Baclofen, Diazepam, Tizanidine enhance GABA activity or inhibit stimulatory neuron signaling.
- Peripheral: Botulinum toxin (Botox) inhibits acetylcholine release; Dantrolene prevents calcium release crucial for muscle contraction.
Intrathecal baclofen may be utilized if oral medications are ineffective.

Additional Therapeutic Options

Anticholinergics such as trihexyphenidyl help manage dystonia, rigidity, and excessive salivation.
Surgical interventions may include:
- Bracing and casting to prevent contractures.
- Soft tissue surgeries to release tension in muscles and tendons.
- Selective dorsal rhizotomy to disrupt sensory nerve pathways and reduce spasticity.
- Surgical stabilization for scoliosis and hip dislocation, using rods or pelvic osteotomies.

Summation

Cerebral palsy encompasses a range of complications requiring coordinated care. Treatment includes medication, therapy, and sometimes surgical options, emphasizing the importance of a holistic, multidisciplinary approach.

Gastrointestinal complications like gastroparesis and constipation can occur.
Aspiration pneumonia risk is increased due to swallowing difficulties.
Joint contractures, muscle weakness, and pain can result from ongoing spasticity.

Treatment Approaches

No cure exists; treatment focuses on managing complications through a multidisciplinary team approach.
Medical management for spasticity includes:
- Central medications: Baclofen, Diazepam, Tizanidine to enhance GABA activity or inhibit stimulatory neurons.
- Peripheral treatments: Botulinum toxin and Dantrolene to limit muscle contraction.

Additional Therapeutic Options

Anticholinergics like trihexyphenidyl manage rigidity, dystonia, and excessive salivation.
Surgical interventions may involve:
- Bracing and casting to prevent contractures.
- Soft tissue surgeries to relieve muscle tension.
- Selective dorsal rhizotomy to mitigate spasticity.
- Surgical stabilization of scoliosis and hip issues using rods or pelvic osteotomies.

Summation

Cerebral palsy involves a spectrum of complications requiring coordinated, multidisciplinary care.
Treatment strategies include medical management, therapy, and potential surgical interventions to enhance quality of life.

Definition and Nature of Cerebral Palsy

Cerebral palsy is a neurodevelopmental disorder caused by upper motor neuron lesions.
The condition is characterized as non-progressive, meaning that the initial damage does not worsen over time.

Etiology

Causes are multifactorial, linked to prenatal factors, the birthing process, and the postnatal period.
Premature birth is the leading cause, often resulting in periventricular leukomalacia (PVL) due to inadequate blood supply affecting the brain's white matter.
Intracranial hemorrhages can affect premature infants, resulting from fragile capillaries near the brain's ventricles.

Intrauterine Infections

Intrauterine infections may lead to cerebral palsy, summarized by the "TORCH" mnemonic:
- Toxoplasmosis
- Rubella
- Cytomegalovirus
- Herpes simplex virus
- Other infections like syphilis, Zika virus, and varicella zoster.

Hypoxic and Ischemic Insults

Factors like placental abruption or previa can cause hypoxia or ischemia by impairing oxygen transfer to the fetus.
Umbilical cord compression during delivery may also lead to oxygen deprivation.

Postnatal Factors

Intracerebral hemorrhage or trauma can result in cerebral palsy after birth.
Infections, such as meningitis or encephalitis, can damage brain tissue.
Kernicterus, stemming from high levels of unconjugated bilirubin from hemolytic anemia, may also result in brain injury.

Genetic Factors

Genetic factors may contribute to vulnerability, with specific mutations affecting glutamate decarboxylase being associated.

Classification of Cerebral Palsy

Types of cerebral palsy include:
- Spastic: Common type featuring hyperreflexia, spasticity, and muscle weakness.
- Dyskinetic: Involves basal ganglia, causing unwanted movements like chorea and dystonia.
- Ataxic: Resulting from cerebellar injury, affecting balance and coordination.
- Mixed: Combines characteristics of the types above.

Upper Motor Neuron Lesion Characteristics

Signs include increased deep tendon reflexes, clonus, spasticity, possible weakness, and pathological reflexes like the Babinski sign.

Specific Forms of Cerebral Palsy

Hemiplegic CP: One body side is affected, with contralateral weakness.
Diplegic CP: Primarily affects lower extremities, with some impact on upper limbs.
Quadriplegic CP: Involves all four limbs, affecting both upper and lower extremities bilaterally.

Dyskinetic Cerebral Palsy

Lesions in the basal ganglia lead to:
- Chorea: Jerky, involuntary movements.
- Athetosis: Slow, snake-like movements.
- Dystonia: Sustained abnormal muscle contractions.

Ataxic Cerebral Palsy

Associated with cerebellar injury, leading to coordination and balance issues, often presenting as gait difficulties.

Cerebellum and Cerebral Palsy

The cerebellum regulates tone, balance, and coordination.
Injury causes hypotonia, ataxia, and coordination deficits such as dysdiadochokinesis and dysmetria.

Complications Associated with Cerebral Palsy

Cognitive impairments and intellectual disabilities may develop due to inadequate brain maturation.
Seizures are commonly associated with cortical neuron involvement.
Visual disturbances can include strabismus and amblyopia.
Hearing loss may occur from inner ear abnormalities.
Neuromuscular scoliosis can develop due to muscle imbalances.
Higher adductor tone frequently leads to scissoring gait, potential hip dislocation, or subluxation.
Speech complications typically manifest as dysarthria and swallowing difficulties (dysphagia).
Excessive salivation (cialorrhea) may arise from impaired secretion control.
Gastrointestinal complications like gastroparesis and constipation can occur.
Aspiration pneumonia risk is increased due to swallowing difficulties.
Joint contractures, muscle weakness, and pain can result from ongoing spasticity.
