A recent study sheds light on the state of Europe's mental and neurological health. The study finds reveal that mental disorders have become Europe's largest health challenge in the 21st century. The study also highlights that the majority of mental disorders remain untreated. Taken together with the large and increasing number of 'disorders of the brain', the true size and burden is even significantly higher. This three-year multi-method study, published today in European Neuropsychopharmacology, covers 30 countries (the European Union plus Switzerland, Iceland and Norway) and a population of 514 million people. All major mental disorders for children and adolescents (2-17), adults (18-65), and the elderly (65+ years) are included, as well as several neurological disorders. The inclusion of the full spectrum of disorders across all age groups, examined simultaneously in a single study, is unprecedented.
The study's key findings include:
- Each year, 38.2% of the EU's population – or 164.8 million people – suffers from a mental disorder.
- Mental disorders are prevalent in all age groups and affect the young as well as the elderly, revealing though differences in what diagnoses are the most frequent.
- The most frequent disorders are anxiety disorders (14.0%), insomnia (7.0%), major depression (6.9%), somatoform disorders (6.3%), alcohol and drug dependence (>4%), attention-deficit and hyperactivity disorders (ADHD, 5% in the young), and dementia (1% among those aged 60-65, 30% among those aged 85 and above).
- Except for substance disorders and mental retardation, no significant cultural or country variations were found.
- No indications for increasing overall rates of mental disorders were found, when compared with the previous comparable study in 2005, which covered a restricted range of 13 diagnoses in adults only. The notable exception is an increase of dementia due to increased life expectancy.
- No improvements were found in the notoriously low treatment rates for mental disorders in comparison with the 2005 data. Still only one third of all cases receive treatment.
- Those few receiving treatment do so with considerable delays of an average of several years and rarely with the appropriate, state-of-the-art therapies.
- Additionally, many millions patients in the EU suffer from neurologic disorders such as stroke, traumatic brain injuries, Parkinson's disease and multiple sclerosis, cases that may have to be counted on top of the above estimates.
- As the result, disorders of the brain, as measured by disability-adjusted life years (DALYs), are the largest contributor to the EU's total morbidity burden, accounting for 26.6% of the total disease burden, covering the full spectrum of all diseases.
- The four most disabling single conditions (in terms of DALY) were depression, dementias, alcohol use and stroke.
- Disciplinary fragmentation in research and practice, with different concepts, approaches and diagnostic systems.
- The marginalisation and stigmatisation of many disorders of the brain.
- The lack of public awareness about the full range of disorders of the brain and their burden on society.

"Second, we have to take into account the developmental pathways of both mental and neurological disorders simultanously. Both groups of disorders share many common mechanism and have reciprocal effects on each other. Only a joint approach of both disciplines, covering the spectrum of disorders of the brain across the lifespan, will lead to an improved understanding of the causes and improved treatments".
