Prenatal diagnosis and pre-manifestation diagnosis in patients with a family history of SCA can be offered.
13 gru 2022 · Spinocerebellar ataxias comprise a large and expanding group of diseases characterized by degeneration of the spinal cord and cerebellum. There are 50 individual spinocerebellar ataxias (as of December 2022) 2 referred to sequentially as SCA1, SCA2, ... in order of their discovery and genetic characterization.
Qualitatively, we compared MRI brain images from SCA3 subjects (Subjects 1-3) and a unaffected subject (Subject 7) (Figure 2). Dilation of the lateral ventricle (red arrow) and fourth ventricle...
Spinocerebellar ataxia 3 (SCA3) is a rare, inherited form of ataxia. Signs and symptoms may begin between childhood and late adulthood and vary greatly.

SCA3 or Machado-Joseph Disease, is caused by a genetic mutation that is passed on from parents to their children. In SCA3, the impairment of nerve cells and nerve fibers causes degeneration of the cerebellum (the coordination center of the brain) and related brain regions.
