    ### Response:
    What are the signs and symptoms of Friedreich ataxia? Symptoms usually begin between the ages of 5 and 15 but can, on occasion, appear in adulthood or even as late as age 75. The first symptom to appear is usually difficulty in walking, or gait ataxia. The ataxia gradually worsens and slowly spreads to the arms and then the trunk.
