12. Unseen Struggles: Sleep Disorders in Friedreich’s Ataxia
The twelfth important fact about FRDA revolves around its impact on sleep. While sleep disorders may not seem as prominent as motor or sensory symptoms, they are a critical aspect of FRDA, profoundly affecting patients’ daily functioning and overall well-being.
Several sleep disturbances are reported in individuals with FRDA. The most common among them is sleep apnea, a potentially serious sleep disorder where breathing repeatedly stops and starts. This can lead to disruptive sleep patterns and excessive daytime sleepiness, significantly impacting daily activities.
Restless legs syndrome (RLS), characterized by an irresistible urge to move one’s legs, especially at rest or during the night, is another sleep-related issue faced by some FRDA patients. This can further contribute to sleep disturbances and a decrease in sleep quality.
The root of these sleep disorders often lies in the nervous system impairment caused by FRDA. The brain’s control over sleep patterns and respiratory functions during sleep can be affected, leading to issues like sleep apnea. Meanwhile, the sensory changes associated with FRDA can contribute to conditions like RLS.
The impacts of these sleep issues are far-reaching. Chronic sleep deprivation can lead to problems like reduced cognitive function, mood swings, and even a weakened immune system. This once again underscores how wide-ranging and complex the effects of FRDA can be, affecting almost every aspect of an individual’s life. (12)
