What Are Stimulants?
Stimulants are a class of drugs that increase brain activity, leading to increased alertness, attention, and energy. They are commonly used to treat conditions like Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy. Common stimulants include amphetamines, methylphenidate, and caffeine. These drugs work by enhancing the effects of neurotransmitters like dopamine and norepinephrine in the brain. While stimulants are effective in improving focus and reducing fatigue, they must be used responsibly to avoid dependence and potential side effects, such as increased heart rate, insomnia, and anxiety.
