DIAGNOSIS DISORDER DRAMA.

In Sri Lanka, it’s quite common that after a first session with a counsellor/psychologist, you’ll leave the practice with a “diagnosis”. That might feel reassuring but in many cases it doesn’t say much.
And even a questionnaire “test” where you are diagnosed as for example “Borderline” might come across as accurate (it’s often given with percentages), but it’s only correlated with symptoms (whether you have several symptoms or not). These questionnaires are useless because they are based on the DSM5 and lack the layeredness and complexity of the different aspects of a mental illness.
What is wrong with this approach is that mental disorders are presented as constructs that can be measured in a similar way as medical illnesses. In the medical model there are physical symptoms that can be corroborated with scans, lab tests, blood pressure, etc. A mental illness (or “disorder”) is just a handful of arbitrary symptoms (with a huge variability!) with no biomarkers to substantiate it.
Take for example “Borderline Personality Disorder” (BPD). It’s a label without any biological/genetic causes. It's an agreement between mental health professionals that a certain number of observations (five out of nine) can be attributed to this label. But why five and not four or six out of eight or ten? Five out of nine means that you can be “Borderline” in 256 ways. And two “Borderliners” can have only one criterion in common and be completely different from the rest. Plus the criteria are very vague (how to substantiate accurately terms like chronic, frantic, inappropriate, recurrent, etc.). Two assessors can come to two completely different diagnoses.
But the main problem with the symptom approach is that it completely ignores the underlying story, which is responsible for the symptoms and explains them.
Some time ago, a young woman came to my practice. In a tense period of almost a month she had become sleep deprived because of preparations for exams at her college. At the same time she had heard that her grandmother was serious ill, which made her feel her heart racing. She had symptoms like being irritable, a racing mind, easily distracted, intensely focused and worried, Since she studied abroad, a foreign psychiatrist had diagnosed her in three minutes as bipolar (hypo-manic episode). But after having spoken with her for half an hour, the story behind the symptoms became clear and also a logical explanation for her behaviour. This was no bipolar disorder at all, but just the consequence of sleep deprivation and concern for her sick grandmother. The young woman went into therapy with me and recovered.
In the case of BPD, countless research studies have demonstrated that in more than 90% of the cases people with the label BPD have been chronically abused in their childhood. This means that there is sufficient evidence that their symptoms have been developed as a result of their traumatic history. It's much better to speak of a complex post-traumatic stress disorder than to label it with BPD. The standard treatment for BPD is Dialectical Behaviour Therapy, but because this treatment only covers the present it’s totally inadequate. A comprehensive treatment like psychodynamic psychotherapy is far more suitable.
