Case in point: a 2013 review supported growth hormone therapy as a treatment for patients with cognitive impairment, theorizing that growth hormone may interact with receptors in the central nervous system associated with learning and memory.20 Another case in point: a 2018 review found that IGF-1 plays a major role in adult brain function and decreases with age, a decrease that seems to precede cognitive decline in the elderly.21 To tie this all together, we can point to a 2012 clinical trial directly examining the effects of tesamorelin on cognitive function
