ADCA Type 1
SCA1: Ataxia type I (the most frequent): motor impairment (pyramidal), optic atrophy, oculomotor paralysis, intelligence disorders;
SCA2: Ataxia type II: retinal degeneration;
SCA3: Ataxia type III: pure cerebellar ataxia;

causative mutations only identified for half of these
mutations in protein kinase C and fibroblast growth factor 14
abormal expansion of a CAG repeat sequence that encodes for an expanded tract of polyglutamine (polyQ) residues within the mutated protein. It is the polyQ SCAs are the subject of the JCB REPRESS review
3. Symptoms
Symptoms onset ~ 25-45. In type I ataxia, equilibrium disorders present. Speech production disorders are a sign of cerebellum damage. Most frequently associated with the impairment of proprioception (perception of one's body parts in space). Later, paralysis of specific types of eye muscles, swallowing disorders, and impairment of the sphincter function can be associated to the primary condition. http://cirrie.buffalo.edu/encyclopedia/en/article/327/
4. Diagnosing The Condition: “Autosomal dominant cerebellar ataxia type I: A review of the phenotypic and genotypic characteristics”
Obtain history of illness/detailed family history
Physical Examination
Neuroimaging depending on initial diagnosis
Magnetic Resonance Imaging (MRI)
Variable neuronal loss and gliosis in regions of the rhombencephalon more than diencephalon and telencephalon and spinal cord
5. Management/Possible Treatments: “Autosomal dominant cerebellar ataxia type I: A review of the phenotypic and genotypic characteristics”
Occupational/Physical Therapy for gait dysfunction
Speech Therapy for dysarthria
Use of mechanical aids
Cane, Walker, Wheelchair
Recognize and effectively treat depression if noticeable
