At first presentation, approximately 60% were found to have limb ataxia, 80% showed some pyramidal involvement and 50% had both pyramidal and cerebellar involvement. [acnr.co.uk]

Nystagmus is sometimes present. [disorders.eyes.arizona.edu]

Clinical description The disease typically presents in the 4th decade (age range 4-74 years). [orpha.net]

• Wheelchair Bound

  Congenital ataxias display symptoms within the first year of life and are often non-progressive, while the late onset ataxias are more commonly progressive and result in patients rapidly becoming wheelchair bound. [centogene.com]

  In the Québecois cases, only 4% used a wheelchair before the age of 18. 19 Mean age to being wheelchair-bound was around 40 (range 17-58) and to death around 50 (range 21-72). 18 From childhood, deep tendon reflexes are frequently increased, but by adulthood [acnr.co.uk]

  Some patients (38%) are wheelchair-bound after disease duration of more than 33 years. Dysphagia and dysarthria are uncommon. [disorders.eyes.arizona.edu]

  In Episodic ataxia type 2 (EA2), ataxia lasts hours to days, with interictal eye movement abnormalities. Exertion and stress commonly precipitate the episodes. [movementdisorders.org]

  Common symptoms of Ataxia are lack of coordination, slurred speech, trouble eating and swallowing, eye movement abnormalities, deterioration of fine motor skills, difficulty walking, gait abnormalities, tremors, and heart problems. [ataxia.org]

  The eye movement abnormalities, dysarthria, and axial dysmetria with distal muscle atrophy and weakness are present at the same time. Distal sensory deficits with lack of sensory nerve action potentials are also present in the lower limbs. [disorders.eyes.arizona.edu]

  This function makes the application of OCT examination and especially of 3D volume scans possible for patients with severe head ataxia or eye movement abnormalities. [journals.plos.org]

• Onset in Adolescence

  Ataxia telangiectasia has many features in common with AOA together with cutaneous and scleral telangiectasiae, diabetes, immunodeficiency and sensitivity to radiation causing tumours. 19 Late-onset Alexander’s disease may have onset in adolescence and [acnr.co.uk]

  SCA11 progresses slowly over decades, with onset between adolescence and young adulthood. All individuals develop gait disorders, increased reflex action, eye disturbances and irregular movements, and speech difficulties. [encyclopedia.com]

• Abnormal Gait

  Ataxia is a neurological feature of abnormal gait due to the lack of appropriate muscle coordination and it is a common clinical symptom in hundreds of different diseases. [centogene.com]

  Other main symptoms are irregularities in the retina of the eye, bone and skin changes, and the abnormal gait, speech patterns, and muscle movements associated with cerebellar ataxia. [encyclopedia.com]

  Furthermore, among the core symptoms of HSP are also included abnormal gait and difficulty in walking, decreased vibratory sense at the ankles, and paresthesia. [10] Individuals with HSP can experience extreme fatigue associated with central nervous system [en.wikipedia.org]

• Spastic Gait

  Dysarthria, dysphagia, and a spastic gait are experienced by the majority of individuals. Hyperreflexia and a positive Babinski sign are commonly presently. Mild cognitive impairment and depression have been seen in a minority of patients. [disorders.eyes.arizona.edu]

  If symptoms begin during the teenage years or later, then spastic gait disturbance usually progresses over many years. [en.wikipedia.org]

• Abnormal Reflex

  The patient showed the classic triad of early childhood-onset cerebellar ataxia, peripheral neuropathy and pyramidal tract signs such as spasticity, abnormal reflexes and the loss of the ability to perform fine motor movements. [e-jmd.org]

In adults, Vitamin E and occasionally Vitamin B-12 deficiency are rarely a cause of chronic progressive ataxia and should not be overlooked in a diagnostic workup. [movementdisorders.org]

• Dyslipidemia

Treatment Treatment Options: No treatment has been reported. [disorders.eyes.arizona.edu]

Management and treatment In the absence of specific treatments to slow or stop disease progression, care is supportive. For example, parkinsonism, restless legs syndrome, spasticity, sleep disorders and depression can be treated pharmacologically. [orpha.net]

Treatment team Neurologists and geneticists are the front line treatment team for people with ataxia, along with specialized nurses and therapists. [encyclopedia.com]

Prognosis Prognosis is poor. In the late stages of the disease, usually 10 to 15 years following onset, bulbar dysfunction secondary to affection of lower medullary nuclei results in aspiration which is life-threatening. [orpha.net]

The prognosis is bleak, with a gradual progression to disability and death within 10-20 years. Ref: Orr, H.T. et al. (1993). Expansion of an unstable CAG trinucleotide repeat in spinocerebellar ataxia type I. Nature Genet. 4, 221-26. [gpnotebook.co.uk]

Prognosis The prognosis for a person with ataxia depends upon the type and nature of the disease. Ataxia as a result of trauma or infection may be a temporary condition, or leave some degree of permanent disability. [encyclopedia.com]

Prognosis [ edit ] Although HSP is a progressive condition, the prognosis for individuals with HSP varies greatly. It primarily affects the legs although there can be some upperbody involvement in some individuals. [en.wikipedia.org]

She divided those with a known etiology (eg, abetalipoproteinemia, ataxia telangiectasia) from those whose etiology was unknown (eg, Friedreich ataxia, Ramsay Hunt syndrome, cerebellar ataxia with retinal degeneration). [medlink.com]

Etiology SCA1 is caused by CAG repeat expansions in the ATXN1 gene region on chromosome 6p23. Prognosis Prognosis is poor. [orpha.net]

These aggregates prevent the ataxin-1 protein from functioning normally, which damages cells and leads to cell death. For reasons that are unclear, aggregates of ataxin-1 are found only in the brain and spinal cord (central nervous system). [ghr.nlm.nih.gov]

Treatment [ edit ] No specific treatment is known that would prevent, slow, or reverse HSP. Available therapies mainly consist of symptomatic medical management and promoting physical and emotional well-being. [en.wikipedia.org]

Conclusion: Establishing the diagnosis in older mentally retarded patients is important in the prevention of medical complications and in the development of management strategies for the institution. [karger.com]
