Therapy in Huntington's disease: where are we [review]?
- View All
As of 2012, almost 20 years after the discovery of the causative gene, clinical research has yet to find a disease-modifying treatment for Huntington's disease. However, both pharmacologic and nonpharmacologic therapies are available for many of the common symptoms of the disease. Recent studies of gene-positive patients in the prodromal, not clinically diagnosable, stages of the disease, are changing our perception of when the process of neurodegeneration begins. Once disease-modifying therapies become available, the approach to the diagnosis of Huntington's disease will likely shift from an examination-based clinical diagnosis, to one that includes a more complex combination of imaging, examination, and biomarker analysis.
