Late-onset cerebellar ataxia
ICD-10 G11.2 is a billable code used to indicate a diagnosis of late-onset cerebellar ataxia.
Late-onset cerebellar ataxia (LOCA) is a neurological condition characterized by the progressive loss of coordination and balance due to degeneration of the cerebellum, which is responsible for motor control. This condition typically manifests in adulthood, often after the age of 40, and can be associated with various hereditary and degenerative diseases. Genetic mutations, particularly in genes such as ATXN1, ATXN2, and ATXN3, are implicated in the pathogenesis of late-onset ataxias. Patients may present with symptoms including gait instability, dysmetria, and intention tremors. The condition can be sporadic or familial, with a family history of ataxia or related neurodegenerative disorders such as Huntington's disease, which may complicate the clinical picture. Diagnosis is primarily clinical, supported by neuroimaging and genetic testing when indicated. Management focuses on symptomatic relief and rehabilitation, as there is currently no cure for the underlying degeneration.
Detailed neurological examination findings, family history, and results of genetic tests.
Patients presenting with gait disturbances, balance issues, and coordination problems.
Ensure comprehensive documentation of neurological assessments and any referrals to genetic counseling.
Genetic test results, family pedigree, and clinical correlation with symptoms.
Patients with a family history of ataxia seeking genetic counseling or testing.
Document the rationale for genetic testing and any findings that may influence management.
Used to assess cognitive function in patients with ataxia.
Document the rationale for testing and results.
Neurologists should ensure that cognitive assessments are linked to the ataxia diagnosis.
Late-onset cerebellar ataxia can be caused by genetic mutations, neurodegenerative diseases, or may occur sporadically without a clear hereditary link.
