Cerebral palsy is a chronic, non-progressive neurological disorder caused by damage to or abnormal development of the immature brain. This damage usually occurs before birth, during delivery, or in the early years of life, when the central nervous system is still highly vulnerable. The primary feature is a disturbance in posture and motor control, often accompanied by spasticity, coordination problems, and, in some cases, additional cognitive or sensory impairments. Although the brain injury itself does not worsen over time, the clinical presentation can evolve due to growth, muscle changes, and secondary complications.

​

The causes of cerebral palsy are varied and can be prenatal, perinatal, or postnatal. Prenatal factors include oxygen deprivation, maternal infections such as rubella or cytomegalovirus, genetic abnormalities, and malformations of brain development. Around the time of birth, complications such as prolonged labor, prematurity, and low birth weight may contribute. Postnatal causes include severe neonatal infections, traumatic brain injury, or stroke in infancy. In all cases, the damage affects brain regions responsible for motor function, such as the motor cortex, basal ganglia, cerebellum, or white matter pathways.

​

The clinical presentation of CP varies widely. In the spastic type there is increased muscle tone and hyperactive reflexes. The dyskinetic type is characterized by involuntary movements such as athetosis or dystonia, while the ataxic type primarily causes balance and coordination difficulties. Many patients present with a mixed pattern. Depending on distribution, CP may involve one limb (monoplegia), one side of the body (hemiplegia), both legs more than the arms (diplegia), or all four limbs (quadriplegia). The severity and functional limitations are often classified using internationally recognized systems such as the Gross Motor Function Classification System (GMFCS) for gross motor skills, the Manual Ability Classification System (MACS) for hand function, and the Communication Function Classification System (CFCS) for communication ability.

​

In addition to motor impairments, cerebral palsy frequently involves comorbidities such as epilepsy, vision and hearing disorders, speech and swallowing difficulties, joint contractures, scoliosis, and hip displacement. Other risks include malnutrition from dysphagia, chronic respiratory infections in severe cases, and psychosocial challenges such as depression and reduced participation in education or work. Life expectancy is usually normal in mild cases but may be reduced in severe cases with significant medical complications.

Diagnosis is based on medical history, observation of motor development, and neurological examination. Brain MRI can reveal structural changes such as periventricular leukomalacia or hemorrhage, while additional genetic or metabolic testing may be indicated to exclude other causes of motor dysfunction.

​

Treatment aims to optimize function and quality of life, requiring a multidisciplinary approach. Physical therapy addresses muscle balance, posture, and motor skills. Occupational therapy focuses on daily living activities and adaptive equipment, while speech therapy targets communication and swallowing. Medications to reduce spasticity include oral agents such as baclofen, intrathecal baclofen pumps, and targeted botulinum toxin injections. Surgical interventions such as tendon lengthening, bone corrections or selective dorsal rhizotomy may be indicated to improve mobility or reduce spasticity permanently. Newer rehabilitation technologies include robot-assisted gait training, functional electrical stimulation, and virtual reality–based therapy to increase engagement and improve motor learning.

The prognosis of CP depends on the severity of motor and cognitive impairment, the timing of intervention, and the availability of support systems. Early recognition and intervention significantly improve functional outcomes. Preventive measures include quality prenatal care, maternal vaccination against infectious diseases, prevention of premature birth, and safe delivery practices. Emerging research is exploring neuroprotective strategies such as magnesium sulfate administration in threatened preterm labor, stem cell therapies to repair neural pathways, and artificial intelligence tools to detect early signs of CP by analyzing infant movement patterns.

​

Cerebral palsy is therefore not a single condition but a complex syndrome in which motor impairments intertwine with neurological, orthopedic, communicative, and psychosocial factors. Lifelong, integrated care is essential, combining medical treatment, rehabilitation, and social support to enable individuals with CP to participate as fully and independently as possible in society.

If you want, I can now adapt this into a medical reference-style version with a table summarizing all CP types, causes, symptoms, and treatments. That would make it easier to use as a quick reference.
