Cerebral Palsy in the Faroe Islands: Birth Prevalence and Clinical Characteristics, 2005–2021

Cerebral palsy is a group of permanent conditions that affect how a person moves and holds their body. It happens when the part of the brain that controls movement is damaged before, during, or shortly after birth. This damage does not get worse over time, but the way it affects a child can change as they grow. Because the brain injury is permanent, the condition can limit a person's ability to walk, talk, or use their hands, and it often comes with other challenges like seizures, learning difficulties, or trouble seeing and hearing. While the condition is the most common cause of physical disability in children, the reasons it happens and how often it occurs can vary greatly depending on where a child is born and the care they receive. Understanding these patterns helps doctors and communities prepare better support systems for families.

In the remote North Atlantic archipelago of the Faroe Islands, a team of researchers set out to fill a gap in global knowledge by studying this condition in their own unique population. The Faroe Islands are home to a small, isolated community of about 55,000 people with a long history of distinct genetics and a single, centralized healthcare system. For decades, there were no reliable records showing how many children in this specific group were born with cerebral palsy. To find the answer, the researchers looked back at medical records from 2005 to 2021, a period that began when the islands' hospitals started using a unified electronic system to track patient data. They focused on every child born during those years who was later confirmed to have the condition, checking their files for details about their birth, their specific type of disability, and any other health issues they faced.

The study identified thirty children with cerebral palsy born in the Faroe Islands during that seventeen-year period. This number translates to a rate of roughly 2.7 cases for every 1,000 live births. While this figure is slightly higher than the average seen across many European countries, the researchers noted that the small size of the island population means the numbers could fluctuate. What stood out most was the makeup of the group: boys were affected much more often than girls, with nearly three boys for every one girl. The children were also diagnosed relatively early, with the median age of diagnosis being just under two years old, which suggests that the local healthcare system is identifying the condition quickly.

When the researchers examined the specific nature of the disabilities, they found a pattern that differed from what is typically seen in larger European studies. More than half of the children had a form of the condition that affected only one side of their body, known as spastic unilateral cerebral palsy. This is a milder form where the child can usually walk without assistance. In contrast, the more severe forms that affect both sides of the body were less common in this group. This distribution is significant because it aligns with the fact that half of these children were born at full term, rather than prematurely. In many other populations, severe cases are often linked to very early births, but here, a large portion of the children were born at their expected due date and still developed the condition, often linked to complications like a lack of oxygen during birth.

The study also painted a detailed picture of the other health challenges these children face. Sleep disorders were the most common companion condition, affecting two-thirds of the group. Intellectual disabilities were present in 60 percent of the children, while vision problems and epilepsy were also frequent. Despite these significant hurdles, the majority of the children were able to walk independently. The researchers emphasized that while the small number of cases makes it difficult to draw broad statistical conclusions, the findings highlight a specific profile for the Faroe Islands: a group of children who are mostly born at full term, often boys, with a tendency toward milder motor impairments but a heavy burden of sleep and cognitive issues.

These findings offer the first clear look at how cerebral palsy presents in this unique population. The researchers suggest that the high rate of sleep problems is an area that deserves more attention from doctors and families, as it is often overlooked. They also point out that because the condition often appeared in children born at full term with signs of birth complications, there may be specific risks during delivery that need closer monitoring. While the study cannot prove exactly why the rates are slightly higher or why the pattern of symptoms is different, it provides a solid foundation for local healthcare providers to plan better support. By understanding that these children face specific challenges like sleep disruption and learning difficulties alongside their movement issues, the community can build a more coordinated system of care to help them thrive.
