MedicalResearch.com: What is the background for this study? What are the main findings?
Response: My larger research agenda is focused on identifying the ways in which environmental and biological influences work collectively to shape behavioral patterns across major stages of the life course. I am particularly interested in identifying environmental influences that can change biological functioning or activity to result in behavioral change.
Brain injury was a natural progression of these interests since brain injury is expected to result in changes in the structure and functioning of the brain, which has been linked to meaningful changes in behavior. There have also been a sizable number of studies that indicate that justice involved populations experience brain injury at a rate that is between five and eight times what is observed in the general population. I was fascinated by this finding and thought that brain injury may be a good candidate influence to investigate further.

MedicalResearch.com: What is the background for this study?
Foundation: This study was conceptualized during a conversation we had, namely, Dr. Yaakov Hoffman, Interdisciplinary department of social sciences, Bar Ilan University, and Professor Menachem Ben-Ezra School of Social Work, Ariel University, following the release of the Antman movie. We are both psychologists who are also avid Marvel superhero fans. In this meaningful conversation we discussed the issue of fear of insects which led to the idea that positive exposure to phobic stimuli (exposure to spider or ants) within the context of Marvel superheroes will lead to robust reduction in phobic symptoms. As most of the conventional treatments for specific phobias use exposure to the phobic stimuli in neutral contexts, we thought that framing the exposure in a positive fun, albeit fantasy context would yield robust results, as well as perhaps reducing stigma.

In a study of healthy volunteers, NIH researchers found that taking short breaks, early and often, may help our brains learn new skills.

MedicalResearch.com: What is the background for this study?
Response: Urban living is one of the most well-established risk factors for adult psychotic disorders such as schizophrenia. However, less is known about the role of the urban environment in subclinical psychotic experiences in childhood and adolescence, such as hearing voices and extreme paranoia. These early psychotic experiences are a developmental risk factor for adult psychotic disorders and a range of other serious mental health problems such as depression and anxiety.
It is therefore important that we understand what factors might contribute to the development of early psychotic experiences so that we might be able to intervene and prevent their onset and progression.
In a cohort of over 2000 UK-born children (The Environmental Risk Longitudinal Twin Study), we have previously shown that subclinical psychotic experiences are also around twice as common among children and teenagers raised in urban versus rural settings. We have also shown that this appears to be partly explained by social features in urban neighbourhoods such as higher crime levels and lower levels of social cohesion.
However, no studies have examined the potential link between air pollution and psychotic experiences. This is despite air pollution being a major health problem worldwide (particularly in cities), and despite emerging evidence linking air pollution to the brain.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: In Finland we have perhaps the most comprehensive and reliable medical registers in the world. Thus, with my research group I have conducted various large studies evaluating association of postmenopausal hormone therapy use and various major diseases (see e.g. the references in the B;MJ paper). There has been various smaller studies indicating that hormone therapy might be protective for all kinds of dementias, also Alzheimer’s disease.
However, we have quite recently shown that hormone therapy seems to lower the mortality risk of vascular dementia but not Alzheimer’s disease (Mikkola TS et al. J Clin Endocrinol Metab 2017;102:870-7). Now in this upcoming BMJ-paper we report in a very large case-control study (83 688 women with Alzheimer’s disease and same number of control women without the disease) that systemic hormone therapy was associated with a 9-17% increased risk of Alzheimer’s disease.
Furthermore, this risk increase is particularly in women using hormone therapy long, for more than 10 years. This was somewhat surprising finding, but it underlines the fact that mechanisms behind Alzheimer’s disease are likely quite different than in vascular dementia, where the risk factors are similar as in cardiovascular disease. We have also shown how hormone therapy protects against cardiovascular disease, particularly in women who initiate hormone therapy soon after menopause.
