Response: Uncontrolled studies in humans have shown conflicting results regarding effects of antipsychotic medications on brain structure. Recent studies in animals (e.g. rats and non-human primates) show that these medications may be associated with brain volume loss. To date, our knowledge of the effects of antipsychotic medications on brain structure in humans have been limited by the lack of a double-blind, randomized, placebo-controlled trial with brain imaging. Ours is the first such study. It is considered unethical to do such a study in people with schizophrenia, because of the life-saving benefits of these medications in this illness. However, in people with depression also experiencing psychosis, it was possible to do such a study once people experienced remission from their illness.

Response: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are chemical groups that have had a wide variety of uses due to their ability to their ability to repel water and stains. They might be found in food packaging, water-repellant clothing and carpeting, paints, fire-fighting foam, and water, for example. Although many are no longer manufactured in the United States, PFAS persist in the environment as they do not readily break down. Adverse health effects have been speculated especially for low birthweight babies, immunological effects, certain cancers and thyroid hormone disruption.1 With these considerations, we hypothesized that there may be an association of PFAS with tooth development and subsequent dental caries (cavities).
