Mental health disorders encompass a wide range of conditions that affect mood, thinking, and behaviour. In the UK, mental health professionals commonly refer to the International Classification of Diseases (ICD-10), published by the World Health Organization (WHO), for diagnosing and classifying mental health disorders. The ICD-10 provides a standardized language for a vast array of conditions, ensuring clarity and consistency in diagnosis and treatment across different healthcare settings
The classification system is divided into different groups, such as mood disorders, anxiety disorders, psychotic disorders, and personality disorders, among others. Each group includes specific types of disorders, which are further categorized based on their characteristics and symptoms.
