Falling
Signs and symptoms of Friedreich's ataxia can include: problems with balance and co-ordination, often causing wobbliness, clumsiness and frequent falls increasingly slurred, slow and unclear speech (dysarthria) increasing weakness in the legs – many people [nhs.uk]
This falls under the category of genetic anticipation. [ citation needed ] Several types of SCA are characterized by repeat expansion of the trinucleotide sequence CAG in DNA that encodes a polyglutamine repeat tract in protein. [en.wikipedia.org]

Workup
In addition to accurate clinical assessment, MRI plays a major role in the diagnostic workup, allowing us to distinguish degenerative conditions from those due to other types of structural damage to the cerebellar or proprioceptive systems. [journals.lww.com]
After the initial workup, 140 patients with cerebellar ataxia remained. [e-jmd.org]
