Autosomal dominant cerebellar ataxia
MONDO:0020380A clinically and genetically heterogeneous group of neurodegenerative diseases characterized by a slowly progressive ataxia of gait, stance and limbs, dysarthria and/or oculomotor disorder, due to cerebellar degeneration in the absence of coexisting diseases. The degenerative process can be limited to the cerebellum (ADCA type 3) or may additionally involve the retina (ADCA type 2), optic nerve, ponto-medullary systems, basal ganglia, cerebral cortex, spinal tracts or peripheral nerves (ADCA type 1). In ACDA type 4, a cerebellar syndrome is associated with epilepsy.
Also known as: SCA, spinocerebellar ataxia, ADCA, Autosomal Dominant Hereditary Ataxia, autosomal dominant spinocerebellar ataxia, cerebellar ataxia, autosomal dominant, Pierre Marie cerebellar ataxia (formerly)

New drug could slow rare brain disease that steals balance
Disease control OngoingThis phase 3 trial tests whether the drug troriluzole can slow the progression of spinocerebellar ataxia, a rare genetic disorder that affects coordination and balance. About 300 adults with different types of SCA are randomly assigned to take either troriluzole or a placebo dail…

Could a drug slow rare brain disease? new study uses Real-World data to find out
Disease control OngoingThis study looks at whether the drug troriluzole can slow the progression of spinocerebellar ataxia (SCA), a rare genetic disease that affects movement and balance. Researchers will compare 909 patients who took troriluzole for up to three years with similar patients who did not …

Brain zaps and rehab: new hope for balance in rare ataxia?
Symptom relief OngoingThis study looks at whether a gentle brain stimulation technique (tDCS) combined with a special exercise program can reduce symptoms of spinocerebellar ataxia, a disease that affects coordination and balance. Fifteen adults who can walk (with or without help) will receive either …

Can a gentle brain zap help people with ataxia walk better?
Symptom relief OngoingThis study tests whether a non-invasive brain stimulation technique called transcranial direct current stimulation (tDCS) can improve movement in people with degenerative ataxia, a rare condition that damages the cerebellum and impairs balance and coordination. Sixteen participan…

Scientists decode gait signatures to spot brain diseases
Knowledge-focused OngoingThis study examines walking patterns in people with Parkinson's disease and similar neurological conditions, as well as healthy volunteers. Researchers aim to identify unique 'gait signatures'—speed-dependent measures of walking—that could help distinguish between different disor…
