PDF Version of the Montreal Protocol for the Evaluation of Communication Manual. The Montreal Evaluation of Communication (MEC) is a clinical test to evaluate language and communication ability in people who have problems with communication in the absence of aphasia such as patients with right hemisphere stroke or damage to the frontal lobes. The MEC kit comprises a manual, a stimulus book, response booklets and informant questionnaires along with audio-files. MEC is designed to provide speech pathologists and neuropsychologists with the means to examine the capacity of their patient to use language to communicate effectively. It assesses higher order language problems including the ability to use and understand lexico-semantic processes, metaphor and pragmatic inference and prosody. Even without a frank aphasic disorder, these kinds of impairments can impact negatively on social and interpersonal functioning and result in reduced social opportunities and quality of life.
