Ritalin affects the central nervous system by stimulating dopamine and norepinephrine activity in the brain. These neurotransmitters are essential for attention, impulse control, and cognitive function. By increasing their availability, Ritalin helps individuals with ADHD improve concentration and reduce hyperactivity. However, misuse or excessive doses can lead to side effects like nervousness, high blood pressure, and dependency, making it important to follow the prescribed dosage carefully.
