Participate Remotely in Microbiome Assessment (MAP ALS)

The Neurological Clinical Research Institute at Massachusetts General Hospital is seeking individuals to participate in a stool collection research study enrolling under the direction of Dr. Katharine Nicholson.
The purpose of the research study is to collect stool samples from people with amyotrophic lateral sclerosis (ALS) and healthy volunteers. Through comparison of these samples, the researchers hope to learn more about the microbiome (i.e. bacterial strains) in the stool of patients with ALS, as well as find unique biological markers, which could be used to develop new therapies. The stool sample collection will be done at home; you do not need to visit MGH to enroll in this study.
You must be at least 18 years of age, answer brief questions about your medical and family history, and give a stool samples. All eligible subjects will provide clinical information and participate in a one-time stool collection. Subjects may enroll in-person at MGH or via phone consent. Stool collection occurs at home. ALS subjects will have the option to participate in up to 2 additional brief visits collecting only clinical information, 3 months and 6 months after the first visit.
