The growing number of diagnoses, particularly in Western societies, has coincided with a global rise in mental health problems. According to the World Health Organisation, mental health disorders are now the leading cause of disability worldwide, with conditions like depression, anxiety, and psychosis becoming more prevalent. This increasing trend has been described as a “mental health epidemic,” but is it truly an epidemic of mental illness, or is it more about the way we have come to understand and categorise mental distress?
The sharp rise in diagnoses cannot solely be attributed to an actual increase in mental health problems. The growth of the mental health industry, has created a system in which many individuals are identified as having disorders, even when their experiences may not be pathological in the strictest sense. It’s possible that these tools have created a self-fulfilling prophecy, where people who might have otherwise adapted to challenges in their lives are now labelled as “sick” and in need of treatment.
In many cases, the over-categorisation of human emotion and behaviour risks turning normal human experiences—such as grief, stress, or anxiety—into clinical conditions. This can make people feel as though they are constantly battling mental illness, even when their symptoms may be part of the natural human condition.
Over-Categorisation and the Medicalisation of Human Nature
As psychiatric diagnostic tools have become more refined, the scope of what is considered a mental health disorder has expanded. Normal human experiences such as anxiety, sadness, or stress—common reactions to life events like a job loss or the death of a loved one—are increasingly being labelled as clinical conditions. The fine lines between what constitutes normal psychological distress and what qualifies as a diagnosable disorder are often blurred.
In fact, the DSM-5 has faced criticism for contributing to the over-diagnosis of relatively minor or transient conditions. For instance, what was once considered a natural response to grief, such as sadness after the loss of a loved one, can now be diagnosed as major depressive disorder if it persists for a certain length of time. Similarly, the increasing number of disorders in the DSM-5 has led to concerns about pathologising normal human behaviour. Conditions like generalised anxiety disorder or attention-deficit hyperactivity disorder (ADHD) may be diagnosed even when symptoms do not meet the clinical threshold, leading some to question whether psychiatry is over-complicating what are essentially variations of human experience.
This trend towards over-diagnosis is not just an issue for the individual, but has wider societal implications. When everyday experiences are medicalised, individuals may begin to see themselves as inherently “broken” or diseased, rather than recognising that their struggles are part of the complex fabric of being human. This pathologisation can also lead to unnecessary treatment, with people turning to medication or therapy for what might simply be a temporary emotional response.
The Need for a New Paradigm in Psychiatric Research and Practice
Given these concerns, it is clear that the field of psychiatry is at a crossroads. The historical foundations laid by Kraepelin were vital in moving psychiatry toward a more structured, scientific understanding of mental illness. But as diagnostic tools have become more detailed and comprehensive, we must ask whether we’ve reached a point where standardisation has gone too far, leading to an over-medicalisation of everyday human struggles.
The current mental health crisis calls for a shift in perspective. Instead of focusing solely on labels and diagnostic criteria, we need to look more holistically at the causes of mental distress. Environmental factors, social isolation, economic instability, and the impact of climate change are critical components that cannot be ignored. Mental health must be understood not just as a set of symptoms to be categorised and treated, but as a complex interplay of biological, psychological, and social factors.
Kraepelin’s Legacy: The Birth of Psychiatric Classification
Emil Kraepelin is widely regarded as the father of modern psychiatric classification. His work in the late 19th and early 20th centuries marked the beginning of a systematic approach to understanding and categorising mental disorders. Kraepelin introduced the concept of longitudinal observation, classifying mental illnesses not just by their symptoms, but by their course over time. His descriptions of conditions like schizophrenia and bipolar disorder are still influential today.
However, Kraepelin’s methods were based on clinical observation and lacked the statistical tools and diagnostic criteria that we now use. His classification system was relatively broad. It relied on subjective assessment and description. Consequently, it was more prone to variation. It was also less reproducible than modern systems. Moreover, Kraepelin’s view of mental illness as a form of biological degeneration has been largely debunked. Advances in neurobiology and genetics prompted this change. Contemporary research, such as that led by Professor Robin Murray, has shifted the understanding of psychosis and other disorders from a purely biological model to one that considers genetic predisposition, environmental stressors, and socio-cultural factors.
Despite its limitations, Kraepelin’s pioneering work laid the foundation for the DSM (Diagnostic and Statistical Manual of Mental Disorders). It also laid the groundwork for the ICD (International Classification of Disease). Psychiatric diagnostic tools have evolved over the years. The classification of mental disorders has become increasingly standardised. It has also become increasingly complex. These developments have allowed for clearer communication. They have also improved treatment protocols. However, they may have led to the overcomplication of human nature. This has fueled a mental health crisis. Many are questioning whether we have over-medicalised the human experience.
These standardised systems have undoubtedly improved diagnostic accuracy. They have also improved communication among healthcare providers. However, they bring their own set of challenges, particularly in the context of the mental health crisis we face today.
Conclusion: From Kraepelin to Today – Rethinking Mental Health Diagnosis
By over-categorising human experience and medicalising normal emotional responses, we risk turning ordinary human struggles into clinical conditions, exacerbating the very mental health crisis these tools were designed to address.
As we move forward, we propose a more balanced approach. This approach respects the complexities of human experience. It also ensures that serious mental health conditions are properly diagnosed and treated. The challenge is to develop a mental health framework that promotes well-being. It should reduce the stigma of seeking help. Additionally, it must foster a deeper understanding of the socio-environmental factors that contribute to mental distress. Ultimately, we need a new paradigm for understanding psychiatric challenges. This new paradigm should value neurodiversity and human complexity. It must support holistic treatment and provide a more compassionate, less pathologised view of mental health.
