Diagnostic inflation, more medication, higher daily doses
In the past decades the diagnoses ADHD have become almost inflationary. Between 1989 and 2001, the number of diagnoses in German clinical practise increased by 381 percent. The costs for ADHD medication, such as for the performance-enhancer Methylphenidate, have grown 9 times between 1993 and 2003. The German health insurance company, Techniker, reports an increase of 30 percent in Methylphenidate prescriptions for its clients between the ages of 6 and 18. Similarly, the daily dosage has increased by 10 percent on average.
Remarkable lack of research
Considering these statistics, there is a remarkable lack of research in the diagnostic of ADHD. "In spite of the strong public interest, only very few empirical studies have addressed this issue", Prof. Schneider and Dr. Bruchmller point out. While in the 70s and 80s a "certain upswing" of studies on the frequency and reasons for misdiagnoses could be observed, current research hardly examines the phenomena. The current study shows that in order to avoid a misdiagnosis of ADHD and premature treatment, it is crucial for therapists not to rely on their intuition, instead to strictly adhere to defined, established diagnostic criteria. This is best possible with the help of standardized diagnostic instruments, such as diagnostic interviews.
