A new study, published in the Archives of Neurology, showed that a drug approved for HIV, Egrifta (growth hormone releasing hormone (GHRH) analog) has favorable effects on cognition in adults. Healthy adults who injected themselves nightly showed an improvement of 200% in executive function, e.g., using memory to plan and strategize tasks. Adults with mild cognitive impairment still showed decline in executive function, but the decline was not as dramatic as placebo. Side effects include skin reactions as well as increased joint pain. The drug costs $22,500 dollars for a 30 day supply. Previous studies suggest exercise may have a similar benefit on cognition.  What else do you recommend to your patients to improve cognition?
