ICD-11 should not repeat the mistakes made by DSM-5.

Having two systems of psychiatric diagnosis creates unnecessary confusion therefore it would be desirable to achieve increased consistency between ICD-11 and DSM-5. Unfortunately, however, DSM-5 has included many controversial suggestions that have weak scientific support and insufficient risk-benefit analysis. As a result ICD-11 should learn from the DSM-5 mistakes rather than repeating them.
