Huntington disease (HD) is an autosomal-dominant, incurable, progressive disorder that manifests with chorea and behavioral and cognitive impairment. The disease usually occurs during the fourth or fifth decade of life; however, it may present at any age. Clinical suspicion is confirmed by genetic testing. Death occurs, on average, 15 to 20 years after the onset of symptoms. Here we report about a Hispanic woman and her family who were affected by the disease; this case illustrates the role of cultural values and beliefs in the decision-making process, as well as the importance of the physician's cultural competency in fostering a trusting relationship that may lessen the burden of catastrophic diseases on individuals, families, and society at-large.
