Research is exploring the relationship between the longevity factor klotho and various health conditions, including chronic psychological stress. Studies suggest that klotho may be linked to conditions such as attention-deficit hyperactivity disorder, depression, and hypothyroidism, and may also play a role in antioxidant defenses and neurogenesis. The exact nature of these relationships is still being investigated, with some studies examining the potential for klotho to serve as a biomarker or influencer of disease susceptibility.
