Researchers discovered that glucocorticoids, a class of medications frequently prescribed to treat autoimmune and inflammatory skin conditions, may physically alter the form and structure of a patient's brain in addition to raising the possibility of mental health problems. According to the study, the prescribed steroids are associated with a higher risk of depression, fatigue, and other health issues.
Effects of Glucocorticoids on Humans
Millions of individuals in Britain take steroids to treat a variety of ailments, including arthritis, eczema, COPD, and asthma, as well as to suppress the immune system in those with autoimmune diseases, according to the Telegraph.
Although prolonged systemic glucocorticoid administration has been associated with potential long-term negative effects, there is little evidence to support this association.
The effects of systemic, via injection or pill, and inhaled glucocorticoids on humans over time were studied by researchers from Leiden University in the Netherlands.
The medications function by suppressing an individual's immune response to stop molecules from being released that target and attack their own organs. Dexamethasone, cortisone, and budesonide are a few examples of these substances.
Findings from Study About Steroids' Effect on Human
The UK Biobank project's nearly 800 patients, the bulk of whom are in their 60s, were included in the study. The researchers had access to their detailed medical data as well as MRI scans of their brains. In order to identify any variations in gray and white matter, the brains of the patients were compared to more than 24,000 other individuals with comparable health, age, and demographics.
Use of systemic as well as inhaled glucocorticoids was linked to physically distinct white and grey matter, with systemic delivery of the medicines being more strongly implicated.
According to the study, which was published in the journal BMJ Open, systemic usage was linked to a greater amount of gray matter in the brain's caudate structure, but users who breathed the substance had less gray matter in their amygdala.
The study's design prevents the researchers from conclusively stating that steroids induce brain changes, but they do state that it is likely given the new information and other results.
Depression Effects on Steroid Usage
According to the results, those who use systemic steroids are also 90% more likely to experience tiredness and 76% more likely to have depressive symptoms. Additionally, those using systemic steroids are 84% more likely to report struggling with apathy and 78% more likely to report restlessness. However, the researchers were unable to distinguish between those receiving infusions and those taking pills.
Inhaled steroid users were reported to be 35% more likely to report feeling exhausted or lethargic but had no higher risk for other diseases.
This study, according to the authors, shows that use of both systemic and inhaled glucocorticoids is related to alterations in multiple brain imaging parameters in the large population-based cohort of the UK Biobank.
Inhaled glucocorticoid users had the smallest effect sizes, systemic glucocorticoid users had greater effect sizes, and chronic systemic glucocorticoid users had the biggest effect sizes, according to analyses of patients who use glucocorticoids on a long-term basis.
The researchers note that given how widely used prescribed steroids are, the findings are extraordinary.
