In turn, the diagnosis of AD was based on the criteria of the National Institute of Neurological and Communicative Disorders and Stroke/Alzheimer’s Disease and Related Disorders Association (NINCDS/ADRA). The MCI diagnosis was defined based on the criteria of Petersen. The occupational therapist who applied the MoCA-BR did not participate in the consensus meeting for selection and classification of the elderly, in an effort to avoid the risk of bias by using the information on the MoCA-BR performance for the definition of a cognitive diagnosis. The exclusion criteria for the AD group were: a diagnosis of mixed dementia (AD associated with another type of dementia), and moderate or advanced stages of dementia evaluated by CDR.Ĭonsidering the inclusion and exclusion criteria in the medical interview, past and current medical histories of the elderly, and the performance of a complete neuropsychological evaluation performed by an experience professional, a team composed of a psychiatrist, a neuropsychologist, and a geriatric doctor classified, following a consensus meeting, the participants selected for the control group, the MCI group, and the AD CDR 1 group. The inclusion criteria for the AD group were: age ≥65 years education ≥4 years a clinical diagnosis of Alzheimer’s disease (AD), supported by neuropsychological tests showing cognitive impairment and a functional evaluation showing a decrease in functionality and mild stage dementia, evaluated through CDR, corresponding to a score equal to 1 using this tool. The exclusion criterion for the MCI group was a diagnosis of dementia. The inclusion criteria of the MCI group were: age ≥65 years education ≥4 years a subjective cognitive complaint, preferably confirmed by an informant an objective cognitive deficit confirmed by a low performance under the level expected on neuropsychological tests normal general cognitive functions and intact or minimally impaired functional activities.

The exclusion criteria for the control group were: a diagnosis of dementia a diagnosis of relevant neurological or psychiatric diseases or systematic uncontrolled chronic diseases that have an impact on cognition a history of alcoholism or substance abuse aphasia or a visual, hearing, or motor handicap evidence of loss of autonomy or independence in daily activities regular use of psychotropic drugs and altered performance on neuropsychological tests.

The inclusion criteria for the control group were: age ≥65 years and education ≥4 years.
