ADHD and stimulants



ADHD can affect people differently.  It depends on the type of ADHD symptoms a person is struggling with.  Also, symptoms can exacerbate situations based on how the individual is feeling at the moment.  Attention Deficit Hyperactivity Disorder (ADHD) is a condition that affects school-aged children through adulthood with symptoms ranging from difficulty sustaining attention to hyperactivity (American Psychiatric Association, 2000). 

Treatments vary for ADHD, but the most predominant treatment is the use of psychostimulant medications such as methylphenidate, also known as Ritalin (Graziano, Geffken & Lall, 2011).  However, in spite of the successful history Ritalin to manage ADHD symptoms, it is still unknown how or why methylphenidate works for this condition (Novartis, ND).   Methylphenidate is a form of amphetamine that affects the part of the brain that controls impulsivity, hyperactivity, and lack of focus.  This drug has been used for decades to manage ADHD-like behaviors. 

In their research,  Graziano, Geffken, and Lall (2011) employed parent-rating scales to measure the effectiveness of methylphenidate with children diagnosed with ADHD.  The results suggested that stimulant medication, such as methylphenidate, appears to relieve the hyperactive and impulsive symptoms of ADHD in school-aged children, allowing them to display improved cognitive functioning, such as longer sustained attention, as compared to subjects taking non-stimulant medication (Graziano, Geffken, & Lall, 2011).  

Although Novartis clearly states that the effectiveness of Ritalin on ADHD symptom management is unclear, the outcome appears to be very obvious.  Subjects observed while taking stimulant medication displayed noticeably improved cognitive skills as opposed to before the administration of the medication.  However, the behavioral assessments completed by parents and teachers seem to correlate stimulant medication to improved symptom management for ADHD individuals.
