Clonazepam, also known as Klonopin, is a controlled substance that can help treat anxiety disorders. This drug does affect the chemical makeup of the brain, and it can become addictive. Klonopin has not been shown to aid in rewiring the brain, especially not in a beneficial way – but it has been reported to be helpful to those that are prescribed it and need it to lessen their symptoms of anxiety and seizures in acute settings and under strict medical supervision.
