The prevalence of this condition is estimated at 1 per 10,000 or 20,000 individuals, but with variations in different regions and ethnic groups3. The phenotype of HD is characterized by impairments in motor skills (e.g., tic movements, changes in gait, stiffness, etc.), cognitive skills (e.g., deficits in visual memory, auditory, verbal and attention), and behavioral changes, psychological and language13,5.
