    en.wikipedia.org/wiki/Spinocerebellar_ataxia

    Spinocerebellar ataxia (SCA) is a progressive, degenerative, [1] genetic disease with multiple types, each of which could be considered a neurological condition in its own right. An estimated 150,000 people in the United States have a diagnosis of spinocerebellar ataxia at any given time .

    en.wikipedia.org/wiki/Spinocerebellar_ataxia_type_1

    Ataxia refers to a lack of coordinated muscle movements that include gait abnormality and is the cerebellar sign that typifies all spinocerebellar ataxia (SCA) types, though individuals with SCA1 also develop pyramidal and bulbar signs as the disease progresses. The average age of onset is between 30 and 40 years of age, though exceptions exist.

  4. Autosomal dominant cerebellar ataxia - Wikipedia

    Spinocerebellar ataxia type 15 has been classified as an ADCA Type III as it has been noted to have postural and action tremor in addition to cerebellar ataxia. [4] Additionally, spinocerebellar ataxia type 20 (SCA20) is organized in ADCA III that often exhibits disease-like symptoms at an earlier age, sometime starting at fourteen years old ...

    Machado–Joseph disease (MJD), also known as Machado–Joseph Azorean disease, Machado's disease, Joseph's disease or spinocerebellar ataxia type 3 (SCA3), is a rare autosomal dominantly inherited neurodegenerative disease that causes progressive cerebellar ataxia, [1] [2] which results in a lack of muscle control and coordination of the upper and lower extremities. [3]

    Spinocerebellar ataxia type 6 (SCA6) is a rare, late-onset, autosomal dominant disorder, which, like other types of SCA, is characterized by dysarthria, oculomotor disorders, peripheral neuropathy, and ataxia of the gait, stance, and limbs due to cerebellar dysfunction. Unlike other types, SCA 6 is not fatal.

  7. Spinocerebellar ataxia type-13 - Wikipedia

    en.wikipedia.org/wiki/Spinocerebellar_ataxia_type-13

    SCA13 is typified by early onset, mildly progressive cerebellar ataxia with accompanying dysarthria, mental retardation, and nystagmus. Symptoms and age of onset can vary slightly according to the causative mutation. [1] [2]

  8. Friedreich's ataxia - Wikipedia

    en.wikipedia.org/wiki/Friedreich's_ataxia

    Friedreich's ataxia (FRDA) is a rare, inherited, autosomal recessive neurodegenerative disorder that primarily affects the nervous system, causing progressive damage to the spinal cord, peripheral nerves, and cerebellum, leading to impaired muscle coordination . The condition typically manifests in childhood or adolescence, with initial ...

  9. Cerebellar ataxia - Wikipedia

    en.wikipedia.org/wiki/Cerebellar_ataxia

    Cerebellar ataxia is a form of ataxia originating in the cerebellum. [1] Non-progressive congenital ataxia (NPCA) is a classical presentation of cerebral ataxias. Cerebellar ataxia can occur as a result of many diseases and may present with symptoms of an inability to coordinate balance, gait, extremity and eye movements. [ 2 ]
