Stressing about aging damages your brain, shortens your life

Dementia, disrespect, and loneliness – that is not your future, says aging expert Ashton Applewhite.

  • The best anti-aging advice? Stop stereotyping old people! Cultural messaging about the pitfalls of old age causes undue stress that prematurely ages the brain and shortens life spans.
  • People who have a positive outlook on aging can live 7.5 years longer than those who buy into cultural stereotypes about getting old.
  • It's important to look at the positives of aging, not just the risk factors: Alzheimer's rates are declining, 'mental sifting' can make us wiser, and older workers injure themselves less often than younger workers.

What if you were immune to chronic pain? Vaccines could make it happen.

Scientists are developing vaccines for migraines and sciatica (back pain) – a win in the war against the overprescription of opioid drugs.

  • Alzheimer's disease and unintentional deaths (like opioid overdoses and suicides) have been driving down U.S. longevity statistics for three consecutive years – a trend not seen since the Spanish flu pandemic.
  • Our current approach to treating chronic pain is drug-based, but a vaccine-based approach can cut addiction out of the equation.
  • You can vaccinate against pain! Scientists are developing vaccines for migraines and sciatica, which will lower the need for opioids, be cheaper, and make drug non-compliance a non-issue.

'Self is not entirely lost in dementia,' argues new review

The assumption "that without memory, there can be no self" is wrong, say researchers.

In the past when scholars have reflected on the psychological impact of dementia they have frequently referred to the loss of the "self" in dramatic and devastating terms, using language such as the "unbecoming of the self" or the "disintegration" of the self. In a new review released as a preprint at PsyArXiv, an international team of psychologists led by Muireann Irish at the University of Sydney challenge this bleak picture which they attribute to the common, but mistaken, assumption "that without memory, there can be no self" (as encapsulated by the line from Hume: "Memory alone… 'tis to be considered… as the source of personal identity").

Alzheimer's disease: Scientists restore memory in mice through epigenetic treatment

A new study shows promise for epigenetic treatments for humans suffering from Alzheimer's disease.

  • A new study on mice with Alzheimer's disease claims to have identified the key epigenetic factor that leads to memory loss from Alzheimer's disease.
  • Using a drug treatment that blocked a particular set of enzymes, the scientists were able to restore memory functions in mice.
  • Epigenetics is a relatively new field, but its treatments could someday change the way we treat disease.
