The Role of Gut Flora in Alzheimer's Disease


This study seeks to correlate data about participants' gut microbiome (the community of viruses, bacteria and other microbes in the digestive system) with information about their Alzheimer's disease status.

  • History of bariatric surgery, total colectomy with ileorectal anastomosis or proctocolectomy
  • Postoperative stoma, ostomy or ileoanal pouch
  • Participation in any experimental drug protocol within the past 12 weeks
