Abstract
Introduction
In this analysis, Datamonitor estimates that there were a total of 19.3 million cases of ADHD in 2010 in the seven major markets, with nearly 60% of these cases present in the US. Prevalence rates for ADHD are expected to remain constant, and therefore any changes in prevalence will depend on population dynamics in the seven major markets.
Features And Benefits
• Gain insight into market potential, including a robust 10-year epidemiology forecast of prevalent ADHD cases.
• Understand the key epidemiologic risk factors associated with ADHD.
Highlights
Datamonitor expects an increase in ADHD cases through to 2021 in the seven major markets as a result of population growth.
Conduct disorders can cause severe distress as well as social, interpersonal, and occupational impairment.
Your Key Questions Answered
• What are the most robust epidemiologic studies for ADHD prevalence data?
• How will the patient population change through to 2021 in the US, Japan, and the five major EU markets (France, Germany, Italy, Spain, and the UK)?
• How do changes in population structure and risk factors affect the trend in prevalent ADHD cases?

Summary
DISEASE DEFINITION AND DIAGNOSIS CRITERIA
Definition of attention deficit hyperactivity disorder
Diagnostic criteria
Specific diagnostic tool: the rating scale
GLOBAL VARIATION AND HISTORICAL TRENDS
Changes in diagnostic criteria and data comparability
Global variation: similar prevalence rates worldwide
Comparable ADHD rates in the seven major markets
Large number of US-based ADHD research affected prevalence rates
ADHD prevalence rates worldwide: differences influenced by perceptions
Adult ADHD: persists in nearly half of diagnosed children
Historical trend: increased disease recognition and a change in definition influenced rates
Over-diagnosis: most common when functional impairment is not considered in the diagnosis
DRIVERS OF ATTENTION DEFICIT HYPERACTIVITY DISORDER
Risk factors
Family history: most evident risk factor
Pregnancy and delivery complications: poor maternal health increase the risk of ADHD
Psychosocial events: ADHD associated with low socioeconomic issues
Sex and race: risk of ADHD is higher in men than women
Co-morbid conditions that alter ADHD epidemiology
Oppositional defiant-disorder and conduct disorder: the most common co-morbidities
Emotional impairment/anxiety: linked to uncontrolled behaviors
Bipolar disorder: overlapping symptoms with ADHD
Cognitive impairment: causes learning disabilities and hinders cognitive development
Addictive behaviors: illicit drugs, alcohol, and smoking
