A comprehensive diagnostic evaluation for complaints of inattention, hyperactivity, and impulsivity, conducted with clinical interview, rating scales, and neuropsychological testing when needed.
Indication
- Children with school inattention, difficulty completing tasks, and hyperactivity complaints
- Adolescents with declining academic performance, procrastination, and organizational problems
- Adults with persistent forgetfulness, distractibility, and impulsivity at work and in personal life
- Suspected coexisting learning disorder, anxiety, or depression
- Detailed evaluation before treatment in individuals with a presumptive ADHD diagnosis
- Need for differential diagnosis from medical/psychiatric causes (sleep disorder, thyroid dysfunction, depression)
Preparation
- Reports/observations from family, school, and workplace (when applicable) are collected
- Previous medical reports, developmental history, and school records are brought
- Rating scales such as Conners and ASRS (Adult ADHD Self-Report Scale) are completed prior to evaluation
- Stimulant intake such as caffeine may be limited on the day of assessment
- Information is gathered from both parents and teachers in children
How it's performed
- Developmental history, age of symptom onset, and duration are explored in the clinical interview
- Symptom severity is scored with standardized scales such as Conners (child/adolescent) and ASRS (adult)
- Neuropsychological tests measuring attention, working memory, and executive function are administered when needed
- Thyroid function tests, iron/ferritin, and sleep evaluation may be planned to rule out medical causes
- Coexisting learning disorder, anxiety, depression, and substance use are screened
- Findings are evaluated against DSM-5 criteria; diagnosis, differential diagnosis, and treatment plan are shared
Post-procedure
- If treatment is decided, psychoeducation, behavioral interventions, and medication when needed are planned
- If medication is initiated, the response and side effects of options such as methylphenidate are monitored at 2-4 week intervals
- Height, weight, and blood pressure are measured regularly in children
- Academic and occupational functioning, social skills, and self-esteem are followed
- Additional interventions are considered for coexisting disorders (anxiety, learning disorder)
Risks
- False positive or false negative diagnosis (especially when other coexisting conditions are present)
- When medication is chosen, side effects such as sleep problems, decreased appetite, headache, and mild increase in heart rate
- Stigma and labeling concerns — minimized through informed consent
- Continuation of academic/occupational difficulties if treatment plan is not followed
- Exacerbation if comorbid depression and substance use risk are overlooked
FAQ
Does ADHD only occur in children?
No. Symptoms begin in childhood; however, many individuals may receive a diagnosis for the first time in adulthood. In adults, distractibility and organizational difficulties may be more prominent.
Can the diagnosis be made with a single test?
A single test cannot diagnose ADHD. Diagnosis is established by combining clinical interview, rating scales, information from multiple sources (family, school), and neuropsychological tests when needed.
Is medication mandatory?
Medication is not mandatory. Depending on symptom severity, functional impairment, age, and coexisting conditions, psychoeducation, behavioral approaches, and school/work accommodations may be the first option. The need for medication is evaluated together with the physician.
Does methylphenidate cause addiction?
When used as prescribed and at appropriate doses, the addiction risk of methylphenidate is markedly low. Use without prescription or misuse is strongly discouraged.
