Australian jihadist who posted decapitated head image is ‘paranoid schizophrenic’

An Australian Islamist who proudly published a photo of his seven-year-old son holding a severed head in Syria is – according to psychiatrists who treated him – a paranoid schizophrenic who has hallucinated for years.

Days after he was widely described in Australia as “a lunatic”, convicted terrorist Khaled Sharrouf was confirmed as a paranoid, schizophrenic depressive who has suffered mental illness since the 1990s by Dr Olav Nielssen, a leading Australian psychiatrist.

Dr Nielssen treated Sharrouf in 2005 after he was charged with plotting terrorist attacks in Sydney and Melbourne.

How could they tell?
