A new study reinforces the risks of steroids and why anabolic androgenic steroid (AAS) use is not recommended as a means to enhance athletic performance or increase muscle mass. Researchers from Oslo University Hospital revealed the risks of steroids, finding that using AAS over time accelerates brain aging, which is linked with cognitive impairment and a higher risk for neurodegenerative diseases. Steroid hormones readily enter the brain, and receptors for sex hormones are found throughout the brain.

“This important study  shows in a large sample that [AAS] use is associated with deviant brain aging, with a potential impact on quality of life in older age,” said lead study author Astrid Bjornebekk, PhD, Oslo University Hospital.
