The research and examinations by ScienceDirect unpack the effects of caffeine on the human body. The reason behind the research is that caffeine causes body-focused repetitive behaviours. Body-focused repetitive behaviours (BFRBs) are heterogenous and have various types. Type 1 is an “automatic” BFRBs, while type 2 is goal directed “focused” style of BFRB. At the moment, there is a lack of FDA-approved BFRBs, which is reflected in the lack of knowledge by professionals to further FDA-approved approaches. This is where individuals are looking online for treatment advice with regards to the effect of BFRBs. The study of caffeine on BFRBs needs more accurate results and research done, as FDA medications have also not yet been approved for BFRBs. The article further mentions, “future research should aim to characterise the neural mechanisms of BFRBs to better understand the root of these seemingly opposing forces. Moderate doses of caffeine or psychostimulants, such as those used for ADHD, may be interesting medications to study for BFRBs in well-controlled clinical trials.”
