Abstract:
This study aimed to investigate the therapeutic effects of N-acetyl-D-mannosamine (ManNAc) on age-related cognitive dysfunction in dogs. ManNAc was administered to 5 dogs with low cognitive levels for 2 months, and the cognitive ability and active-resting cycle were periodically assessed for improvement. ManNAc treatment significantly reduced the number of error trials in the place-learning test, especially in the first month of administration. Three ManNAc-treated dogs also showed improvement in the active-resting cycle. In conclusion, ManNAc treatment appears to alleviate age-related cognitive dysfunction.
