Which complication frequently develops in patients with Friedreich ataxia aside from cardiomyopathy?

In patients with Friedreich ataxia, aside from cardiomyopathy, respiratory complications are indeed common. This neurodegenerative condition affects the spinal cord and peripheral nerves, leading to progressive ataxia and muscle weakness. As the disease progresses, it can also impact the muscles involved in respiration, resulting in respiratory muscle weakness. This impairment can lead to a reduced ability to cough effectively, putting patients at higher risk for respiratory infections and complications such as pneumonia.

The presence of respiratory complications highlights the importance of monitoring lung function and implementing strategies to support respiratory health in individuals with Friedreich ataxia. It is essential for healthcare providers to be vigilant about these aspects of the disease, as they can significantly affect the patient's quality of life and overall prognosis.

While other complications such as diabetes mellitus and bone fractures are associated with various conditions or secondary effects of inactivity, respiratory issues are more directly linked to the motor neuron involvement characteristic of Friedreich ataxia. Furthermore, hypothyroidism, although it can occur in the general population, is not specifically linked to Friedreich ataxia and is less frequently encountered as a complication in these patients. Overall, respiratory complications are a significant concern in the management of Friedreich ataxia.
