In our hospitals and psychiatric clinics, it has already begun. Increasing numbers of people are seeking help for mental health problems associated, in one way or another, with Covid-19. Professionals warn that the psychiatric effects of the pandemic and the lockdown will endure much longer than the physical effects of the virus. And those psychiatric effects are alarmingly diverse: anxiety, psychosis, eating disorders, PTSD. Prof Fiona McNicholas is a Consultant in Child and Adolescent Psychiatry at Crumlin Children's Hospital. She talks about the tsunami of mental health problems we face, the unexpected ways Covid-19 can harm our minds, and the potential for technology to aid therapy in a time of social distancing.
