Neuropsychological tests including cognitive tests such as the mini–mental state examination (MMSE), the Montreal Cognitive Assessment (MoCA) and the Mini-Cog are widely used to aid in diagnosis of the cognitive impairments in AD.[134] These tests may not always be accurate, as they lack sensitivity to mild cognitive impairment, and can be biased by language or attention problems;[134] more comprehensive test arrays are necessary for high reliability of results, particularly in the earliest stages of the disease.[135][136]
