Perspectives of ADHD: Causes and Effects Attention Deficit Hyperactivity Disorder (ADHD) was once referred to as “mental restlessness” by Sir Alexander Crichton in 1798 (Wikipedia, 2012).

The diagnosis is made based on behaviors and not seen as a neurological disease. These symptoms occur in all areas of a child’s life and often worsen when more attention is required (Foley, 2011). There is no definitive cause for ADHD. Researchers are investigating both environmental and biological factors to determine where the true cause lies. The findings appear to point to multiple reasons for the development of this disorder. Regardless of the cause, the effects can have a detrimental impact on both the individual and the family throughout a lifetime. Attention Deficit Hyperactivity Disorder is classified into three subtypes: Predominantly hyperactive-impulsive, predominantly inattentive, and combined hyperactive-impulsive and inattentive (Foley, 2011). The majority of children diagnosed with ADHD are in the third subtype which exhibits both hyperactivity and inattentiveness (Foley, 2011) The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) states nine different behaviors associated with ADHD which are failing to pay close attention to details or making careless mistakes, having difficulty sustaining attention, not listening, not following through, having difficulty organizing, having low task persistence, losing things, being easily distracted, being forgetful, fidgeting, being out
