Yes, it's a well-established scientific fact that the age-related cognitive decline begins as early as one's twenties: [1][2][3][4]. As of now there really is no cure for this, except for trying various lifestyle interventions in hopes of modifying the slope of the curve in desired direction (standardized cognitive tests help one select the most favorable interventions). The obvious stuff - exercising twice weekly, cardio, sleeping well & enough, being less stressed help noticeably. Beyond this there is a trove of supplements and drugs that may, though likely not, help.
Naturally, highly intelligent people understand this unfortunate truth of nature pretty well, and plan their lives so as to decouple their living standard from their peak intellectual performance. Thus we see smart people becoming managers and investors/rentiers over time. Once your money works for you by virtue of compounding interest, not much intelligence is needed.
