Conclusions: Observed patterns in search behavior align with known behaviors and those highlighted by survey respondents. These observations suggest that searchers showing intensive interest in MSD may be patients who have been prescribed these drugs. Given behavioral dynamics, we surmise that the days on which MSD queries are made may coincide with commencement of mania or depression. Although we do not have data on mood changes and whether users have been diagnosed with bipolar illness, we see evidence of cycling in people who show interest in MSD and further show that we can predict impending shifts in behavior and interest. %M 24568936 %R 10.2196/jmir.2664 %U //www.mybigtv.com/2014/2/e65/ %U https://doi.org/10.2196/jmir.2664 %U http://www.ncbi.nlm.nih.gov/pubmed/24568936
