Abstract: Provided is an accurate, minimally invasive method for diagnosing dementia or mild cognitive impairment. The method for examining the likelihood of mild cognitive impairment or dementia, or the risk of dementia includes the steps of: measuring the amount of stereoisomers of proline in the biological sample collected from a subject; and comparing the level of D-proline with a reference value.
