Speech, language and swallowing in Huntington’ Disease

Abstract

Huntington’s disease (HD) has been described as a genetic condition caused by a mutation in the CAG (cytosine-adenine-guanine) nucleotide sequence. Depending on the stage of the disease, people may have difficulties in speech, language and swallowing. The purpose of this paper is to describe these difficulties in detail, as well as to provide an account on speech and language therapy approach to this condition. Regarding speech, it is worth noticing that characteristics typical of hyperkinetic dysarthria can be found due to underlying choreic movements. The speech of people with HD tends to show shorter sentences, with much simpler syntactic structures, and difficulties in tasks that require complex cognitive processing. Moreover, swallowing may present dysphagia that progresses as the disease develops. A timely, comprehensive and effective speech-language intervention is essential to improve the quality of life of people and contribute to their communicative welfare.
