In this review, we analyzed previously reported SCA15 phenotypes and present a novel SCA15 phenotype. We also address important considerations for evaluating patients with complex hereditary movement disorders. [mayoclinic.pure.elsevier.com]

We also present genetic analyses for all subjects and longitudinal MRI data for one affected subject. [openaccess.city.ac.uk]

All affected members present with cognitive impairment and two of them with mild intermittent involuntary movements in association with the clinical hallmarks of SCA15 (gait ataxia, balance impairment, and dysarthria). [ncbi.nlm.nih.gov]

  CLINICAL CHARACTERISTICS: Spinocerebellar ataxia type 15 (SCA15) is characterized by slowly progressive gait and limb ataxia, often in combination with ataxic dysarthria, titubation, upper limb postural tremor, mild hyperreflexia, gaze-evoked nystagmus [ncbi.nlm.nih.gov]

MANAGEMENT: Treatment of manifestations: Physical and occupational therapy; management of neurogenic dysphagia, if it occurs. [ncbi.nlm.nih.gov]

In addition, new neurophysiological and imaging techniques are discussed, along with an in-depth examination of the treatment and management protocols of ataxic diseases. [books.google.com]

There is no effective treatment known to modify disease progression. Patients may benefit from occupational and physical therapy for gait dysfunction and speech therapy for dysarthria. [malacards.org]

Prognosis Prognosis is generally good and life-shortening events do not usually occur. Some patients live beyond 80 years of age. [orpha.net]

SCA Type 3, also known as Machado-Joseph disease (MJD) is the most common (21%) of all SCAs and shares the same prognosis of 10-20 years. [spinocerebellarataxia.org]

Prognosis Spinocerebellar ataxias due to repeat expansion mutations usually become sick in middle age. In addition to ataxia, other neurological findings are often present depending on the variant of SCA. [verywell.com]

They most likely affected the clinical severity and also the cause of the poor prognosis. SCA31 is an autosomal dominant disorder with adult onset and a slowly progressive pure cerebellar ataxia. [karger.com]

Beginning with an examination of the cerebellar region, and then progressing to a fresh perspective on the clinical aspects of the various forms of ataxia, this handbook gives clinicians a state-of-the-art reference for the management of the many etiologies [books.google.com]

Etiology Genetic testing has shown that patients originally classified under SCA15 and SCA16 have the same subtype caused by a deletion in the inositol 1,4,5-triphosphate receptor 1 ITPR1 gene (3p26.1). [orpha.net]

Differential diagnoses revealed no signs of metabolic or inflammatory etiologies. The cerebellar symptoms gradually worsened. His SARA score was 21 at the age of 62 years. Fig. 1. Sagittal T1-weighted MRI showing cerebellar atrophy ( a, arrow). [karger.com]

Summary Epidemiology Prevalence is unknown. Fewer than 80 patients affected by the disease have been identified to date. Clinical description Age of onset is from 20 to 66 years (mean age 39.6 years). [orpha.net]
