Longevidade e ADN

https://www.noticiasaominuto.com.br/tech/835650/cientistas-criam-teste-de-dna-capaz-de-prever-quando-se-vai-morrer

Citando:
"Os acadêmicos concluíram que as áreas de DNA com maior impacto na longevidade eram aquelas que haviam sido previamente associadas à incidência de doenças fatais, incluindo patologias cardíacas e condições relacionadas com o consumo de tabaco.

Peter Joshi, um dos coordenadores do estudo, disse em declarações ao The Telegraph: "Se tivermos em consideração 100 pessoas no momento do seu nascimento, ou mais tarde, e usarmos a nossa longevidade para os dividirmos em 10 grupos, o grupo de topo irá viver em média cinco anos a mais do que o inferior”."

Teste prevê idade aparecimento de Alzheimer

Citando:
"Scientists have developed a new genetic test for Alzheimer’s risk that can be used to predict the age at which a person will develop the disease.

A high score on the test, which is based on 31 genetic markers, can translate to being diagnosed many years earlier than those with a low-risk genetic profile, the study found. Those ranked in the top 10% in terms of risk were more than three times as likely to develop Alzheimer’s during the course of the study, and did so more than a decade before those who ranked in the lowest 10%."

"while genetic makeup can influence the chances of developing dementia, a healthy diet, regular physical activity and remaining mentally active can also drive down the risk. “Genetics is only part of the story and we know that lifestyle factors also influence our risk of developing Alzheimer’s,” she said. “The best current evidence points to habits we can all adopt to help lower our risk and indicates that what’s good for your heart is also good for the brain.”"

Teste a quão bem se está a envelhecer?

Citando:
"The test looks for an "ageing signature" in your body's cells by comparing the behaviour of 150 genes. It was developed by initially comparing 54,000 markers of gene activity in healthy, but largely sedentary, 25 and 65-year-olds and then whittling them down to a final 150."

Estes testes poderão ser utilizados para ajustar os cuidados de saúde à idade real (o que é muito diferente da idade calculada pela data de nascimento, muito usada pelos médicos).
