5 Major Symptoms of Friedreich’s Ataxia

Friedreich’s ataxia (FA) is a rare genetic disorder where the body produces antibodies that limit the production of frataxin, a protein vital for nerve and muscle health. A lack of frataxin leads to muscle depletion and other symptoms. While the disease can develop at any time, it typically presents between the ages of 10 and 15. According to healthline.com and the Friedreich’s Ataxia Research Alliance, here are some of the most common symptoms associated with the disease.

Difficulty walking
The legs can be affected in different ways by Friedreich’s ataxia, including muscle weakness, weak or lack of leg reflexes, poor coordination and balance, foot deformities, and not being able to sense vibrations in the lower limbs, which all make walking difficult. FA is a progressive disease so walking will become more labored over time with many requiring walking aids or a wheelchair by early adulthood.

Sensory changes
Friedreich’s ataxia is a neuromuscular disease so it can also attack the senses. Symptoms such as loss of hearing, involuntary eye movements, vision impairment, and speech problems may be experienced.

Scoliosis
Weakened core and leg muscles can lead to aggressive scoliosis or curvature of the spine in many patients.

Heart disease
Around three-quarters of people with Friedreich’s ataxia will develop some form of heart disease, usually hypertrophic cardiomyopathy which is when the heart muscle becomes thickened.

Diabetes mellitus 
It’s estimated that between 10 and 20 percent of people living with Friedreich’s ataxia go on to develop diabetes and will become insulin dependent.
