Mild cognitive impairment and everyday functioning in older adults.
The relations between mild cognitive impairment without dementia (MCI/CIND) and everyday functional abilities were examined using data from the Canadian Study of Health and Aging (CSHA). Individuals were identified with MCI/CIND if both caregiver report and clinician judgment agreed on the presence of cognitive impairment in the absence of dementia. Cross-sectional and longitudinal comparisons indicated that individuals with MCI/CIND demonstrated a broad range of impairment in instrumental activites of daily living (IADL) compared to individuals with no cognitive impairment (NCI). In cross-sectional analyses, neuropsychological measures of memory and psychomotor speed were significantly related to impairment in eight areas of functioning. In addition, poorer memory performance was significantly predictive of future impairment in money management.
