Study Summary

Diseases caused by brain energy supply defects can be innate (fibromyalgia secondary to familial mitochondrial disorders) or acquired (tardive dyskinesia or weight gain associated with prolonged antipsychotic use). Patients with these possible mitochondrial disorders will provide a baseline resting heart rate sample, ingest low-dose metformin (500 mg), and then provide an additional sample 2 hours later.

Primary Outcome

ratio of the standard deviation of sampled intervals between each heart beat for ten minutes at time 1 (prior to metformin ingestion) over standard deviation of the sampled intervals between each heart beat for ten minutes at time 2 (2 hours post metformin ingestion)
