[A Brazilian Portuguese version for the ADCS-CGIC scale].

Given increasing research into new therapies for dementia, especially for Alzheimer disease, it has become clear that traditional methods of evaluation, centered on cognition, have proved insufficient. Thus, scales for behavioral disturbances and activities of daily living have been added. Nevertheless, some observations of clinical significant changes, as reported by caregivers, could be overlooked. Clinician's impression of global change scales (CIGIC) are based on broader information and may detect more subtle changes. Typically they take into consideration caregiver information, that which is seen by the health professional during the interview, and may also include brief cognitive tests. We present a Brazilian Portuguese version of a widely used scale of this type, specifically designed for Alzheimer disease (ADCS-CGIC), being the result of the recommended method of translation, back-translation and version by panel consensus.
