Response: My co-authors and I conducted this study to fill a knowledge gap and to inform the work of Project TENDR. No systematic or scoping review had examined both exposure disparities and the joint effects of combined exposures of environmental neurotoxicants and social disadvantage as they relate to disparities in neurodevelopmental outcomes specifically among children living in the U.S.
Our study is the first to summarize the evidence on 7 neurotoxicants that children in the U.S. are routinely exposed to and we examined both disparities in these exposures and disparities in the effects of those exposures on children’s brain development, cognition, and behavior by race, ethnicity, and economic status.
We reviewed over 200 independent studies spanning five decades from 1974 to 2022 on social disparities in exposure to 7 exemplar neurotoxic chemicals and pollutants, including chemical mixtures, and their relationship with disparities with neurodevelopmental outcomes among children in the U.S.
One of the most startling aspects of the connection between schizophrenia and substance abuse is the high prevalence of substance use disorders among those with schizophrenia. Studies consistently show that individuals diagnosed with schizophrenia are more likely to engage in substance abuse compared to the general population. This connection can be best demonstrated using the self-medication hypothesis. According to this hypothesis, individuals with schizophrenia may turn to substances as a way to self-medicate or alleviate their distressing symptoms. Imagine dealing with hallucinations or disorganized thoughts—some may use alcohol or drugs to temporarily escape from this internal turmoil.It is imperative to note that drug abuse does not in any way lead to schizophrenia. However, the misuse of drugs can be a catalyst if an individual is predisposed to the condition or if they are already experiencing mild symptoms. (more…)
MedicalResearch.com Interview with: Lotfi Khemiri Centre for Psychiatry Research Stockholm, Sweden MedicalResearch.com: What is the background for this study? Response: Our study used large-scale national register data in close to 2 million children, and found that parental abuse of both alcohol and drugs are associated with increased risk of intellectual disability in the offspring. Importantly, the risk increase was observed in both mothers and fathers which to the best of our knowledge is a novel finding, and may be explained by both genetic and environmental factors including toxic effects of substance intake on fetal development.
