Early-onset FA tied to greater relationship challenges in later stages
Study finds psychosocial needs differed by age at symptom onset
Written by |
People whose Friedreich’s ataxia (FA) symptoms began in childhood or adolescence may face greater relationship-related challenges at more advanced disability stages than those whose symptoms started in adulthood, a study suggests.
While both groups reported a similar overall number of adverse life events, relationship-related difficulties were more common among nonambulant participants whose symptoms began before age 18. By contrast, people whose symptoms began in adulthood more often reported challenges related to work and family responsibilities, such as hindered professional development and reduced activities with their children.
The findings suggest that “psychosocial support should be offered preemptively at the start of diagnosis,” and that “disease management strategies should be tailored to different age groups,” the researchers wrote.
Study examines how age at FA onset shapes everyday challenges
The study, “Transitional Life Events in Friedreich Ataxia: Differential Age at Onset Perspectives,” was published in The Cerebellum.
FA is a rare inherited disease that progressively damages the nervous system, leading to worsening problems with balance, coordination, speech, and movement. Symptoms most often begin during childhood or adolescence, although some people do not develop the disease until adulthood.
When FA starts early in life, it can profoundly affect more than physical health. Children and adolescents must cope with a progressive neurological disease during a critical period of identity formation, emotional and social development, and increasing independence.
In the social sciences, major changes and challenges that require people to adjust to a new way of living are known as life events. In FA, these events may stem from the disease itself, such as worsening disability, or from the developmental milestones children and adolescents are expected to reach as they grow.
Because children, adolescents, and adults face different priorities and responsibilities, the researchers hypothesized that the life events experienced by people with pediatric-onset FA would differ from those reported by people whose symptoms began in adulthood.
Researchers compare life events in 73 people with FA
To better understand how the age at which FA begins is associated with everyday life, a team led by researchers in Germany analyzed data from an ongoing observational study, dubbed PROFA (NCT05943002), which follows people with FA at six specialized centers across Austria, France, and Germany.
The analysis included 73 people with FA, ages 13 to 67, who had completed an 18-item questionnaire about common transitional life events by Dec. 1, 2025. Participants also completed separate assessments of their overall health and mental well-being. Forty-four participants had pediatric-onset FA, with symptoms beginning before age 18, while 29 had adult-onset disease.
People in the pediatric-onset group were significantly younger (mean age 28.2 vs. 47.2) and had developed symptoms earlier (12.3 vs. 30.4 years). They also reported lower mental well-being.
Overall, the two groups reported a similar mean number of adverse life events (5.4 vs. 5.2). In both groups, disease-related life events were reported most often, followed by relationship-related life events.
However, different patterns emerged across disability stages. Among people with pediatric-onset FA, the number of adverse life events tended to be higher at more advanced disability stages. This trend was driven by a significant rise in relationship-related life events, which were more common among participants who could no longer walk independently. In contrast, no clear pattern was seen among participants whose symptoms began in adulthood.
Relationship and work challenges differed by onset age
Types of life events also differed between the groups. Adults with later-onset FA more often reported that the disease had hindered their professional development, reduced activities with their children, or that their partner had become an important source of support. People with pediatric-onset FA were more likely to report difficulty discussing their illness with others and a negative effect of FA on their personal relationships.
Statistical analyses supported these findings, showing that the association between disability status and relationship-related life events was much stronger in people with pediatric-onset FA than in those with adult-onset disease. Better mental well-being was also associated with fewer adverse life events overall, and particularly with disease- and relationship-related events.
The researchers said these differences may reflect the stage of life at which FA begins. Children and adolescents are still developing their independence, identity, and social relationships, while adults may already have established partners, careers, and support networks when symptoms appear.
Based on these findings, the researchers argued that psychosocial support should be tailored according to when symptoms first appear. They suggested children and adolescents with FA may benefit from earlier “support focused on identity formation and the internalization of the chronic illness,” while adults may need “practical support” for “professional development and domestic assistance (e.g., childcare).”
