Keep looking for biological causes

A letter from our February edition.

11 January 2016

I wonder if a group exists within our profession, increasingly uncompromising in its opposition to possible biological bases of 'functional' mental health difficulties, that would advocate the abandonment of broad-based research into such factors.

I also wonder if the view would be shared by the proportion of young people who become severely unwell and go on to receive diagnoses of schizophrenia but who actually have a form of autoimmune encephalitis, an inflammatory illness of the brain, treatable with immunotherapy (Lennox et al., 2012). It is now thought that perhaps 5 to 10 per cent of cases of first episode psychosis may be caused by antibodies identifiable by current methods (Zandi et al., 2011) (encephalitis has historically been recognised as classically neurological: headaches, seizures, cognitive and language disturbance, even coma and death).

For the benefit of our patients/clients, and for professional credibility, it is important to be tolerant of the potentially diverse origins of future advances in mental health care.
