How OCD Shapes Lives in Unexpected and Painful Ways

Obsessive-compulsive disorder (OCD) affects between one and three percent of the population, taking countless forms with no fixed diagnostic rules. For some, it means relentless rituals; for others, disturbing intrusive thoughts. Two individuals, Mirco Biscioni and Céline Müller, have lived with its challenges since childhood and adolescence, each facing very different symptoms. Mirco Biscioni's OCD began in childhood, shaping his daily life in extreme ways. As a boy, he developed an elaborate bedtime ritual to guard against dying from gas poisoning in his sleep. Later, his fears expanded: he tracked every doorknob he touched, terrified of contracting an illness. By last autumn, his compulsions had intensified, centring on washing and repetitive checking.

For Céline Müller, the disorder took a different form. As a teenager, she battled intrusive thoughts about her sexual orientation, convinced she might be gay despite identifying as straight. Psychotherapist Paul Lukas recognises this as Sexual Orientation OCD, a subtype where sufferers question their identity relentlessly. Müller also endured distressing thoughts about harassing strangers in public—urges she found horrifying but couldn't ignore. Over the past 20 years, OCD treatment has shifted dramatically. Early approaches relied on medication (like SSRIs) and basic cognitive behavioural therapy (CBT). Today, exposure and response prevention (ERP) is the leading method, often combined with newer techniques such as deep brain stimulation for severe cases. Therapies like Acceptance and Commitment Therapy (ACT) and digital interventions have also gained ground. In Switzerland, specialised clinics—including one at the University of Zurich—now offer these treatments, with teletherapy improving access since the COVID-19 pandemic. Red flags for OCD include compulsions that consume excessive time or disrupt daily life. While symptoms vary widely, the disorder's core features remain: persistent intrusive thoughts and repetitive behaviours aimed at easing distress.

Biscioni and Müller's experiences highlight how OCD can manifest in vastly different ways. Advances in therapy, from ERP to digital support, now provide more options for those struggling. Yet the condition's impact—whether through rituals or intrusive thoughts—remains a daily reality for many.
