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.

Examination method for dementia or risk thereof

A material which promotes ammonia metabolism in the body, as well as a material which has excellent ammonia metabolism improving effect and is effective for endurance enhancement and anti-fatigue are provided. An ammonia metabolism promoting agent, comprising catechins as an active ingredient. An agent for preventing or ameliorating hyperammonemia, hepatic encephalopathy or chronic fatigue syndrome, comprising catechins compound as an active ingredient. An ammonia metabolism promoting agent, an endurance enhancing agent and an anti-fatigue agent, comprising catechins, citrulline and arginine as active ingredients.

Ammonia metabolism promoter

A material which has excellent ammonia metabolism improving effect and is effective for endurance enhancement, anti-fatigue or the like is provided. An ammonia metabolism promoting agent, comprising catechins and ornithine as active ingredients. An endurance enhancing agent, comprising catechins and ornithine as active ingredients. An anti-fatigue agent, comprising catechins and ornithine as active ingredients. An agent for suppressing a reduction in blood glucose level by exercise, comprising catechins and ornithine as active ingredients. An agent for promoting recovery from reduced blood glucose level by exercise, comprising catechins and ornithine as active ingredients. An agent for suppressing a reduction in muscle glycogen by exercise, comprising catechins and ornithine as active ingredients. A muscle endurance enhancing agent, comprising catechins and ornithine as active ingredients. An agent for preventing or ameliorating hyperammonemia, hepatic encephalopathy or chronic fatigue syndrome, comprising catechins and ornithine as active ingredients.
