Mice with isolated GH deficiency (IGHD) due to GHRH receptor mutations live longer than their normal siblings with an extended healthspan, i.e., the period of life free from disabilities. Human IGHD individuals due to a mutation in the GHRH receptor gene from Itabaianinha, Brazil, has a normal lifespan with an extended healthspan (1). Our hypothesis is that their aging is accompanied by a delayed cognitive decline. Accordingly, we used the Literacy Independent Cognitive Assess...

Population aging has become a universal worldwide phenomenon. Developing countries (such as Portuguese-speaking countries, with a high rate of illiteracy) will see the greatest increase in the absolute number of elderly people, and dementia disorders will pose enormous challenges to public health in these countries. Although the decline in GH secretion with age has been associated with deleterious conditions of aging, our understanding is the opposite, that the decline in GH s...
