Kenji, a young man who recently relocated from Japan to the UK, has spent the last six months confined to his bedroom, refusing to speak to others or seek employment, and experiencing profound feelings of emptiness. A UK clinical psychologist has diagnosed Kenji with major depressive disorder using the DSM-5. However, Kenji's family believes his condition is hikikomori, a culture-bound syndrome well-recognised in Japan. A second psychologist who assessed Kenji suggested his symptoms instead indicate the negative phase of schizophrenia or an avoidant personality disorder.
