  5. study that sought to examine the association of sleep duration
  6. at age 50 60 and 70 with incident dementia and
  7. to investigate whether patterns of change and sleep duration over
  8. this period were associated with dementia.
  9. The study was originally published to the Journal Nature Communications.
  10. In late April 2021, The study found that those getting
  11. less than six hours of sleep consistently in their 50s
  12. 60's Are 30 more likely to develop dementia than those

  18. 10,000 British civil servants.
  19. This dementia study consisted of 7,959 participants who did not
  20. have a pre existing diagnosis of dementia.
  21. Clinical data was collected every 4-5 years and lasted for
  22. two years at a time.
  23. The data was collected through two methods questionnaires and digital
  24. NHS records.
  25. In the questionnaire, researchers asked the participants, how many hours
  26. of sleep do you get on an average week?
  27. Night Possible responses were five hours or less?
  28. six, seven, eight and 9 hours or more.
  29. The data obtained through electronic and a chess records was
  30. updated on an annual basis ending on March 31 2019.
  31. There is additional data on an accelerometer assessed sleep duration
  32. available on 4267 of the participants.
  33. The data was collected in 2012 2013.
  34. Of the nearly 8000 participants, 521 were diagnosed with dementia
  35. over a mean follow up period of around 24.5 years.
  36. That's about 6.5 of all participants with most being diagnosed
  37. in their 70s.
  38. The lowest dimension incidents per 1000 person years was observed
  39. among those who slept seven hours per night.
  40. The findings suggested that short sleep duration in midlife is
  41. associated with an increased risk of the onset dementia irrespective
  42. of age.
  43. There was no clear evidence of an association between long
  44. sleep duration and incident dementia.
  45. These findings were consistent with the results of the 2012

  57. Currently, more than six million people live with Dementia in
  58. America. That number is expected to reach nearly 13 million
