Insights
Post-neonatal cerebral palsy (CP) rates decreased from 1976-90, primarily caused by infections. Low birthweight increased CP risk, and post-neonatal CP cases showed more severe functional patterns.
Area of Science:
- Pediatrics
- Neurology
- Public Health
Background:
- Cerebral palsy (CP) is a group of disorders affecting movement and posture.
- Post-neonatal CP arises after 28 days of birth and before 25 months, with distinct etiologies.
- Understanding trends and risk factors for post-neonatal CP is crucial for prevention.
Purpose of the Study:
- To determine the incidence and temporal trends of post-neonatal CP.
- To investigate the causes and risk factors associated with post-neonatal CP.
- To compare the characteristics of post-neonatal CP with other forms of CP.
Main Methods:
- Analysis of a European database and seven registers (Surveillance of Cerebral Palsy in Europe collaboration).
- Inclusion of children with post-neonatal CP born between 1976 and 1990.
- Etiological classification using a previously published system, achieving 99% case allocation.
Main Results:
- The prevalence of post-neonatal CP was 1.26 per 10,000 live births, showing a significant decrease from 1976-90 (P = 0.011).
- Infections (50%), vascular episodes (20%), and head injury (18%) were the primary causes.
- While overall causes remained stable, infections like Reye's syndrome and non-CNS infections decreased significantly (P < 0.001 and P = 0.004, respectively).
- Low birthweight (<2500 g) was associated with an increased risk of post-neonatal CP (P < 0.001).
- Children with post-neonatal CP exhibited more severe functional impairments compared to those with non-post-neonatal CP.
Conclusions:
- Public health initiatives targeting brain injury prevention in early childhood are essential.
- Continued monitoring of post-neonatal CP frequency and characteristics is necessary to assess the impact of preventive measures.
- Understanding the specific trends within infection-related CP, such as the decline in Reye's syndrome, informs targeted public health strategies.
Abstract:
We aimed to study the rates and trends over time of children with cerebral palsy (CP) of post-neonatal origin (arising more than 28 days after birth, and before the age of 25 months), to examine their aetiology and associated significant risk factors, and to compare them with other CP cases. Children with post-neonatal CP born 1976-90 were identified from a European database and seven registers were included (Surveillance of Cerebral Palsy in Europe collaboration). Using a previously published classification it was possible to allocate an aetiology to 99% of cases. The prevalence rate of post-neonatal CP was 1.26 per 10 000 live births and a significant decrease was observed over the period 1976-90 (P = 0.011). Infection accounted for 50%, vascular episodes for 20% and head injury for 18% of the cases. Although there has been little change in the profile of underlying causes in this period, within the infection group, a significant downward trend was observed for Reye's syndrome (P < 0.001) and non-central nervous system (non-CNS) infection (P = 0.004), but not for meningitis/encephalitis. There was evidence of some increased risk of post-neonatal CP among children with low birthweight (<2500 g) (P < 0.001). Overall children with CP of post-neonatal origin showed a more severe functional pattern than non-post-neonatal CP children. In order to ascertain the impact of public health and other preventive measures aimed at reducing the frequency of brain injury in the first 2 years after birth, it is necessary to continue to monitor the frequency and characteristics of children with post-neonatal CP into the 1990s.
