Study Endpoints

Primary Endpoints

Number of Participants Experiencing Diarrhea Caused by Clostridium Difficile
5 months

Collected at every visit and follow-up phone visits. A rare side effect of Rifaximin is diarrhea caused by clostridium difficile. This is a very serious form of diarrhea that can be fatal if not treated. The investigators will be following the patients closely during treatment and for 2 months following treatment to see if the patient has any signs or symptoms of this diarrhea. If a patient does develop clostridium difficile diarrhea, they will be promptly treated.

Change in ADAS Cog 11 Scores
At baseline and at 3 months

Change in Alzheimer's Disease Assessment Scale - Cognition test with 11 tasks (ADAS Cog 11) scores following 3 months of oral Rifaximin. Scores range from minimum 0 - maximum 70. Higher scores mean worse outcome.

Secondary Endpoints

Change in Tolerability as Measured by Number of Adverse Events (AE).
Baseline, 3 months, 5 months
Change in Cognitive Performance on the Mini-Mental State Exam (MMSE)
Baseline, 3 months
Participants With Treatment Emergent Adverse Events as Reported by the Subject That Required a Change in Safety Measures
Safety will be measured through adverse events throughout study, at month 3 and by phone call at month 5 (2 months after treatment termination).
