For people who cannot be treated with stimulants due to a substance use disorder or other contraindications, atomoxetine is the suggested first line treatment in the UK. In Canada, clinical guidelines suggest that first line treatment be methylphenidate or lisdexamfetamine. Non-stimulant medications are generally second-line treatments in Canada. Non-stimulant medications
The non-stimulant atomoxetine (Strattera), may be an effective treatment for adult ADHD. Although atomoxetine has a half life similar to stimulants it exhibits delayed onset of therapeutic effects similar to antidepressants. Unlike stimulants which are generally controlled substances, atomoxetine lacks addictive potential. It is particularly effective for those with the predominantly inattentive concentration type of attention deficit due to being primarily a norepinephrine reuptake inhibitor. It is often prescribed in adults who cannot tolerate the side effects of amphetamines or methylphenidate. It is also approved for ADHD by the US Food and Drug Administration. A rare but potentially severe side effect includes liver damage and increased suicidal ideation.Viloxazine is a selective norepinephrine reuptake inhibitor that was FDA-approved to treat ADHD in children, adolescents, and adults.Bupropion and desipramine are two antidepressants that have demonstrated some evidence of effectiveness in the management of ADHD particularly when there is comorbid major depression, although antidepressants have lower treatment effect sizes. Psychotherapy
Psychotherapy, including behavioral therapy, can help an adult with ADHD monitor their own behaviour and provide skills for improving organization and efficiency in daily tasks. Research has shown that, alongside medication, psychological interventions in adults can be effective in reducing symptomatic deficiencies.
The DSM-IV criteria for ADHD were, however, tailored towards the type of symptoms that children would show, and might therefore have underestimated the prevalence of ADHD in adults. In 2013, the newer DSM-5 reviewed some of these criteria, with more lenient requirements for the diagnosis, especially in adults, and the age limit for symptoms first arising raised to twelve years. Signs and symptoms
ADHD is a chronic condition, beginning in early childhood that can persist throughout a persons lifetime. It is estimated that 33–66% of children with ADHD will continue to have significant ADHD-related symptoms persisting into adulthood, resulting in a significant impact on education, employment, and interpersonal relationships.Individuals with ADHD exhibit deficiencies in self-regulation and self-motivation which in turn foster problematic characteristics such as distractibility, procrastination, and disorganization. They are often perceived by others as chaotic, with a tendency to need high stimulation to be less distracted and function effectively. The learning potential and overall intelligence of an adult with ADHD, however, is no different from the potential and intelligence of adults who do not have the disorder.Whereas teachers and caregivers responsible for children are often attuned to the symptoms of ADHD, employers and others who interact with adults are less likely to regard such behaviors as a symptom. In part, this is because symptoms do change with maturity; adults who have ADHD are less likely to exhibit obvious hyperactive behaviors.
