By comparing 51 autistic adults and 49 age-matched controls (aged 30-73 years) we tested if (1) the Montreal Cognitive Assessment (MoCA) is more sensitive in measuring cognitive impairments than the Mini Mental State Examination (MMSE) and (2) if we can replicate the MoCA-findings of Powell et al. (2017) with the Dutch MoCA(-NL). Results showed that: (1) The MoCA-NL is more sensitive, and (2) like Powell, no group differences were observed on the MoCA-NL. However, in contrast to Powell, we did not observe that older autistic adults show more impairment than controls on the MoCA-NL. Nonetheless, as the MoCA-NL is more sensitive to cognitive impairment, it is the recommended screener for older autistic adults.
