RT Journal Article SR Electronic T1 Cognitive performance in UK sample of presymptomatic people carrying the gene for Huntington's disease. JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 358 OP 362 DO 10.1136/jmg.32.5.358 VO 32 IS 5 A1 L Blackmore A1 S A Simpson A1 J R Crawford YR 1995 UL http://jmg.bmj.com/content/32/5/358.abstract AB This paper presents an investigation of cognitive ability in 30 subjects at risk for Huntington's disease. Those shown to be at high or low risk for this disease are compared on a wide range of neuropsychological measures. Results indicate only one significant difference between the two groups; those who carry the gene show a higher level of performance on the Corsi Supraspan task. It is suggested, however, that minimal deficits are apparent in the at risk gene carrying group but that current measures of assessment are not sensitive enough to identify them.
