Covid made things worse for many people with obsessive-compulsive disorder. But it also came with a silver lining.
Most people behave in one or more ways that others may consider peculiar, and I am no exception. I want my clothes to match, from shoes to eyeglasses and everything in between(including underwear — a challenge when packing for a trip). If visitors use my kitchen, they're asked to put things back exactly where they were found. In arranging my furniture, countertops and wall-hangings, I strive for symmetry. And I label packaged foods with their expiration dates and place them in my pantry in date order.
I know I'm not the only one with quirks like these that others may consider "so OCD," a reference to obsessive-compulsive disorder. But the clinical syndrome, in which people have unbidden recurring thoughts that lead to repetitive habits, is far more than a collection of quirky behaviours. Rather, it is a highly distressing and chronic neuropsychological condition that can trigger serious anxiety and make it difficult to function well in school, at work or at home.
For someone with OCD, certain circumstances or actions that most people would consider harmless, like touching a doorknob, are believed to have potentially dire consequences that require extreme corrective responses, if not total avoidance. A person may so fear germs, for example, that shaking someone's hand can compel them to wash their own hand 10, 20 or even 30 times to be sure it's clean.
For many, the Covid-19 pandemic only made things worse. Past research has found a potential correlation between traumatic experience and increased risk of developing OCD, as well as worsening symptoms. A person with OCD who already believes dangerous germs lurk everywhere would, understandably, have become paralysed with anxiety by the spread of the novel coronavirus. And indeed, a Danish study published in October found that the early months of the pandemic resulted in increased anxiety and other symptoms in both newly diagnosed and previously treated OCD patients aged 7 to 21.
How serious is OCD?
The disorder often runs in families, and different members can be affected to varying degrees. Symptoms of the condition often begin in childhood or adolescence, afflicting an estimated 1 to 2 per cent of young people and rising to about one in 40 adults. About half are seriously impaired by the disorder, 35 percent moderately affected and 15 per cent mildly affected.
It is not hard to see how the disorder can be so disruptive. A person with OCD who is concerned that they may fail to lock the door, for example, may feel compelled to unlock and relock it over and over. Or they may become unduly stressed and anticipate disaster if a strict routine, like switching a light on and off 10 times, is not followed before leaving a room. Some people with OCD are plagued by taboo thoughts about sex or religion or by a fear of harming themselves or others.
The comedian Howie Mandel, now 65, told MedPage Today in June that he has suffered from OCD since childhood, but wasn't officially diagnosed until many years later after spending most of his life "living in a nightmare" and struggling with an obsession about germs. He has been working to help counter the stigma of mental illness and increase public understanding of OCD in hopes that greater awareness of the disorder will foster early recognition and treatment to avert its life-impairing effects.
"Until the mid-1980s, OCD was considered untreatable," said Caleb W. Lack, a professor of psychology at the University of Central Oklahoma. But now, he said, there are three evidence-based therapies that may be effective, even for the most severely afflicted: psychotherapy, pharmacology and a technique called transcranial magnetic stimulation, which sends magnetic pulses to specific areas of the brain.
Most patients are initially offered a form of cognitive behavioral therapy, called exposure and response prevention. Starting with something least likely to elicit anxiety — for example, showing a used tissue to people with an obsessive fear of contamination — patients are encouraged to resist a compulsive response, like repeated handwashing. Patients are taught to engage in "self-talk," exploring the often irrational thoughts that are going through their heads, until their anxiety level declines.
When they see that no illness has resulted from viewing the tissue, the therapy can progress to a more provocative exposure, like touching the tissue, and so forth, until they overcome their unrealistic fear of contamination. For especially fearful patients, this therapeutic approach is often combined with a medication that counters depression or anxiety.
One silver lining of the pandemic is that it may have allowed more people to get treated remotely through online health services. "With telemedicine, we're able to do very effective treatment for patients, no matter where they may live in relation to the therapist," Dr. Lack said. "Without ever leaving central Oklahoma, I can see patients in 20 states. Patients don't have to be within a 30-mile radius of the therapist. Telemedicine is a real game changer for people who won't or can't leave home."
For highly impaired OCD patients for whom nothing else has worked, the latest option is transcranial magnetic stimulation, or TMS, a noninvasive technique that stimulates nerve cells in the brain and helps to redirect neural circuits that are involved in obsessive thoughts and compulsions.
"It's as if the brain is stuck in a rut, and TMS helps the brain circuitry get on a different path," Dr. Lack explained. As with exposure and response prevention, he said, T.M.S. uses provocative exposures, but combines them with magnetic stimulation to help the brain more effectively resist the urge to respond.
In a study of 167 severely affected OCD patients at 22 clinical sites published in May, 58 percent remained significantly improved after an average of 20 sessions with TMS. The Food and Drug Administration has approved the technique for treating OCD, though many insurance companies are not yet offering coverage.
