ABSTRACT
Language alterations in Huntington's disease (HD) are reported, but their nature and correlation with other cognitive impairments are still under investigation. This study aimed to characterize the language disturbances in HD and to correlate them to motor and cognitive aspects of the disease. We studied 23 HD patients and 23 controls, matched for age and schooling, using the Boston Diagnostic Aphasia Examination, Boston Naming Test, the Token Test, Animal fluency, Action fluency, FAS-COWA, the Symbol Digit Modalities Test, the Stroop Test and the Hooper Visual Organization Test (HVOT). HD patients performed poorer in verbal fluency (p<0.0001), oral comprehension (p<0.0001), repetition (p<0.0001), oral agility (p<0.0001), reading comprehension (p=0.034) and narrative writing (p<0.0001). There was a moderate correlation between the Expressive Component and Language Competency Indexes and the HVOT (r=0.519, p=0.011 and r=0.450, p=0.031, respectively). Language alterations in HD seem to reflect a derangement in both frontostriatal and frontotemporal regions.
RESUMO
Alterações de linguagem são descritas na doença de Huntington (DH), mas sua natureza exata e a correlação com outras funções cognitivas ainda estão em investigação. Os objetivos deste estudo foram caracterizar o prejuízo de linguagem na DH e correlacioná-lo aos aspectos motores e cognitivos da doença. Foram estudados 23 pacientes com DH e 23 controles, equiparados quanto à idade e escolaridade. Usamos os testes de Boston para Diagnóstico da Afasia, de Nomeação de Boston, Token, Modalidades de Símbolos e Dígitos, Stroop, Organização Visual de Hooper (TOVH), fluência de animais, fonêmica e verbos. Pacientes com DH apresentaram pior desempenho na fluência verbal (p<0,0001), compreensão oral (p<0,0001), repetição (p<0,0001), agilidade oral (p<0,0001), compreensão de leitura (p=0,034) e narrativa escrita (p<0,0001). Houve correlação moderada entre os índices Componente de Expressão e Competência de Linguagem e o TOVH (r=0,519, p=0,011 e r=0,450, p=0,031, respectivamente). Alterações de linguagem na DH parecem refletir prejuízos nas regiões frontostriatais e frontotemporais.
