Sixteen clients with learning disabilities, 8 Down's syndrome (DS), 8 non-Down's syndrome (NDS), diagnosed with dementia, were assessed using specially selected neuropsychological assessment tools at two time points separated by six months. DS individuals showed decline in cognitive abilities (p < .005; 1-tailed) (hypothesis 1); NDS showed decline in cognitive abilities (p < .01; 1-tailed; p < .005; 1-tailed) (hypothesis 2); DS individuals showed decline in social abilities (p < .005; 1-tailed) (hypothesis 3), but the NDS did not (hypothesis 4); No significant differences were found in the ability score changes of the two groups (hypotheses 5 & 6). Findings (1-3) support previous studies with participants over 12 months. Hence, the rate of change in these abilities is faster than previously suspected. © 2003 by The Haworth Press, Inc.
