Before attempts to reverse neurotoxicity are done, irreparable harm may have occurred. The chance of serious damage is determined by several parameters, including the neurotoxic involved, the duration of exposure, and the strength of exposure.  Furthermore, the consequences of a neurotoxic vary depending on the individual exposed—some people have a genetic susceptibility to toxins in the same way that some people are allergic to nuts. Abstinence is a critical first step in reversing the impacts of toxicity, alleviating symptoms, and allowing your brain to repair naturally. Another phase is detoxification, which involves medical practitioners using specific therapies to speed up the removal of toxins from the body. Finally, depending on the eventual healing goal, everyone's answer will be slightly different.
