As human life expectancy continues to increase, age-related diseases are the main impediment to enjoying the fruits of longevity. High on the list is Alzheimer’s disease, the incurable neurodegenerative condition that robs sufferers of their memory and eventually leads to death. But valuable progress is being made in the understanding and prevention of the disease. A new study at the Keck School of Medicine of USC in Los Angeles has revealed that biological changes in the brain occur long before symptoms of Alzheimer’s become apparent. The research, led by neuropsychologist Dr. Duke Han, suggests that cognitive tests are able to detect early stage of the disease in people without symptoms. In this in-depth interview, Dr Han argues that routine brain testing should be incorporated into annual physical check ups for people of all ages.FlexBeam red light therapyRecharge Health is offering a discount on the purchase of FlexBeam, the wearable red light therapy device which targets key parts of the body to improve sleep/treat injuries/sooth aches/pains.  Sale price US$369 (down from $449) + an extra $10 off use code equinox  Sale ends Sept 21: 0259 PST DoNotAgeDoNotAge.org is offering listeners to LLAMA a 10% discount on its range of products – NAD boosters, Sirtuin activators, senolytics and more.  Any health queries can be answered by emailing the team at hello@donotage.orgUse the code LLAMA at checkout. - Time-line Mitopure (a highly pure form of Urolithin A) boosts the health of our mitochondria – the battery packs of our cells – and improves muscle strength.
