Sapropterin, also known as tetrahydrobiopterin, is a drug used to treat phenylketonuria (PKU), a genetic disorder that affects the body's ability to break down an amino acid called phenylalanine. However, there is limited research available on the impact of sapropterin on age-related cognitive decline.

A study published in the Journal of Neural Transmission in 2015 [1] investigated the effects of tetrahydrobiopterin on age-related cognitive decline in mice. The study found that mice treated with tetrahydrobiopterin showed improved cognitive function compared to the control group. The researchers suggested that tetrahydrobiopterin may have a protective effect on the aging brain by reducing oxidative stress and inflammation.

Another study published in the journal Neurobiology of Aging in 2018 [2] examined the relationship between tetrahydrobiopterin and cognitive function in older adults. The study found that higher levels of tetrahydrobiopterin in the cerebrospinal fluid were associated with better cognitive performance in tasks that required working memory and executive function.

It is important to note that these studies were conducted on mice and older adults, and further research is needed to determine the impact of sapropterin on age-related cognitive decline in humans.

In conclusion, while there is some evidence to suggest that sapropterin may have a positive impact on age-related cognitive decline, more research is needed to confirm these findings.
