9. Beyond Movement: Sensory Changes in Friedreich’s Ataxia
Though motor-related issues may be the most visually apparent, it is crucial to consider sensory changes that occur in individuals with Friedreich’s Ataxia (FRDA). Reduced or altered sensation can greatly impact the overall quality of life, and it’s an area of FRDA that warrants our attention.
Primarily, FRDA patients may experience diminished sensation in their extremities, specifically their legs and feet. These changes often start subtly, with individuals finding it harder to perceive temperature or pain in these regions. They may also struggle with recognizing the position of their limbs without looking at them, a clinical condition termed as proprioceptive loss.
This loss of sensation also extends to a condition known as peripheral neuropathy. It typically involves symptoms such as tingling, numbness, and burning pain, starting in the lower extremities and gradually working its way up. This progressive sensory loss can add to the difficulties faced in motor coordination and balance.
Another sensory change in FRDA can occur in the auditory domain. While not as common as other symptoms, hearing impairment can occur, either in the form of difficulty in hearing or tinnitus, an incessant ringing sound in the ears. It’s a further example of the multifaceted impacts of FRDA. (9)
