The subjective nature of psychiatric diagnosis

Medicalising natural and normal responses to life experiences is a dangerous game.

This may be the year that makes you mad. A new psychiatrist’s bible will be published in May and already it’s mired in controversy. Many see it as a pretext for scandalous over-diagnosis and drug-pushing.

The Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, has enormous influence in shaping the way mental health research is carried out worldwide. It was first published in 1952 and the most recent edition appeared in 2000. It has taken over 12 years to agree on the contents of the fifth edition, DSM5.

One problem that people have with DSM5is that it will be oldfashioned: it will make no attempt to link behaviour or feelings to what is known about the physical states of the brain, in an era when neuroscience has made enormous advances in relating physiological issues with behavioural issues.

Take grief. Functional magnetic resonance imaging (fMRI) studies show that grieving people have higher activity in various regions of the brain, including the cerebellum and the posterior brainstem. We’ve all seen the results of this in ourselves or others: low mood, low motivation, loss of appetite.

Here’s the next problem: DSM5 will make it easier to medicalise natural human experience. After the new manual is published, psychiatrists will be able to diagnose people who have had two continuous weeks of this as suffering from depression, even if they are recently bereaved. What was normal behaviour last year will become a medical crisis.

The British Psychological Society and the American Psychological Association are among the mental health organisations that have raised concerns about such moves. Medicalising natural and normal responses to life experiences is a dangerous game. So far, more than 14,000 people have signed an open letter to the team drafting DSM5, expressing concern about some of the proposed changes “that have no basis in the scientific literature”. The letter argues that the changes “pose substantial risks to patients/clients, practitioners and the mental health professions in general”.

The pharma says

Particularly vulnerable, they argue, are children and the elderly. That’s because they are most at risk of having pharmaceutical solutions – many of which can have severe adverse side effects – foisted on them. And there’ll be more people and more conditions for which to prescribe drugs. DSM5 will lower the threshold of what it takes to get diagnosed with a disorder and will offer some new disorders, such as “disruptive mood dysregulation disorder”, a diagnosis for children who exhibit temper tantrums and get upset out of proportion to a situation.

Each positive diagnosis will be a candidate for drug treatment, which makes it particularly worrying that a study published in March last year identified strong ties between the pharmaceutical industry and those drafting DSM5.

The subjective nature of the psychiatric diagnosis has always been a problem. Freud knew this but his 1895 attempt at a “project for a scientific psychology” failed miserably. Back then, science had told us very little about the physiology and function of the brain. In 2013, it has revealed a lot more but there are still far too many gaps to claim that subjective analysis is redundant. Neuroscience is advancing fast; let’s hope we won’t need DSM6.

Leader: Trump and an age of disorder

Mr Trump’s disregard for domestic and international norms represents an unprecedented challenge to established institutions.

The US presidency has not always been held by men of distinction and honour, but Donald Trump is by some distance its least qualified occupant. The leader of the world’s sole superpower has no record of political or military service and is ignorant of foreign affairs. Throughout his campaign, he repeatedly showed himself to be a racist, a misogynist, a braggart and a narcissist.

The naive hope that Mr Trump’s victory would herald a great moderation was dispelled by his conduct during the transition. He compared his country’s intelligence services to those of Nazi Germany and repeatedly denied Russian interference in the election. He derided Nato as “obsolete” and predicted the demise of the European Union. He reaffirmed his commitment to dismantling Obamacare and to overturning Roe v Wade. He doled out jobs to white nationalists, protectionists and family members. He denounced US citizens for demonstrating against him. Asked whether he regretted any part of his vulgar campaign, he replied: “No, I won.”

Of all his predilections, Mr Trump’s affection for Vladimir Putin is perhaps the most troubling. When the 2012 Republican presidential nominee, Mitt Romney, warned that Russia was the “number one geopolitical foe” of the US, he was mocked by Barack Obama. Yet his remark proved prescient. Rather than regarding Mr Putin as a foe, however, Mr Trump fetes him as a friend. The Russian president aims to use the US president’s goodwill to secure the removal of American sanctions, recognition of Russia’s annexation of Crimea and respect for the murderous reign of the Syrian president, Bashar al-Assad. He has a worryingly high chance of success.

Whether or not Mr Trump has personal motives for his fealty (as a lurid security dossier alleges), he and Mr Putin share a political outlook. Both men desire a world in which “strongmen” are free to abuse their citizens’ human rights without fear of external rebuke. Mr Trump’s refusal to commit to Nato’s principle of collective defence provides Mr Putin with every incentive to pursue his expansionist desires. The historic achievement of peace and stability in eastern Europe is in danger.

As he seeks reconciliation with Russia, Mr Trump is simultaneously pursuing conflict with China. He broke with precedent by speaking on the telephone with the Taiwanese president, Tsai Ing-wen, and used Twitter to berate the Chinese government. Rex Tillerson, Mr Trump’s secretary of state nominee, has threatened an American blockade of the South China Sea islands.

Mr Trump’s disregard for domestic and international norms represents an unprecedented challenge to established institutions. The US constitution, with its separation of powers, was designed to restrain autocrats such as the new president. Yet, in addition to the White House, the Republicans also control Congress and two-thirds of governorships and state houses. Mr Trump’s first Supreme Court appointment will ensure a conservative judicial majority. The decline of established print titles and the growth of “fake news” weaken another source of accountability.

In these circumstances, there is a heightened responsibility on the US’s allies to challenge, rather than to indulge, Mr Trump. Angela Merkel’s warning that co-operation was conditional on his respect for liberal and democratic values was a model of the former. Michael Gove’s obsequious interview with Mr Trump was a dismal example of the latter.

Theresa May has rightly rebuked the president for his treatment of women and has toughened Britain’s stance against Russian revanchism. Yet, although the UK must maintain working relations with the US, she should not allow the prospect of a future trade deal to skew her attitude towards Mr Trump. Any agreement is years away and the president’s protectionist proclivities could yet thwart British hopes of a beneficial outcome.

The diplomatic and political conventions embodied by the “special relationship” have endured for more than seven decades. However, Mr Trump’s election may necessitate their demise. It was the belief that the UK must stand “shoulder to shoulder” with the US that led Tony Blair into the ruinous Iraq War. In this new age of disorder, Western leaders must avoid being willing accomplices to Mr Trump’s agenda. Intense scepticism, rather than sycophancy, should define their response.
