psychostimulants

Psychostimulants are drugs that increase activity in the brain, enhancing alertness, attention, and energy levels. They work by boosting the release or blocking the reuptake of certain chemicals like dopamine and norepinephrine, which regulate mood, focus, and motivation. Common examples include medications for ADHD, such as methylphenidate, and recreational drugs like cocaine. While they can improve focus and wakefulness, they also carry risks like dependency and side effects, especially if misused. Psychostimulants are used medically under supervision but can be harmful if used improperly.
