Step-by-step explanation:
The most popular form of medication used to treat individuals with ADHD is psychostimulants. Psychostimulants, such as amphetamines and methylphenidate, are commonly prescribed to people diagnosed with ADHD because they increase neurotransmitter activity in specific areas of the brain associated with impulse control, like the prefrontal cortex and basal ganglia. Despite their stimulating nature, these medications have a calming effect on individuals with ADHD. Other types of medication, such as antidepressants, narcotics, and psychotropics, are not typically used as the primary treatment for ADHD.
