Awakwame recorded medical notes diagnosing the woman as having a history of 'satanic ritual abuse' and said her issues could not be addressed by regular treatment.
The woman - known as Patient A - claimed Awakame also told her to get 'nice holy water' before 'switching off' during the consultation at a health centre in Harwich, Essex.
When community psychiatric nurse Martin Rowe later quizzed Awkame whether she she was possessed, the medic replied: 'She may well be' and claimed she had been thrown out of her local church due to her condition.
The doctor's employment with the North Essex Partnership Foundation Trust was terminated the following month.
Awkame - who has since returned to his native Ghana - faced being struck off after he was found guilty in his absence at a medical tribunal of a number of misconduct charges.
The consultation took place on January 23, 2014 when Awakame was treating the vulnerable woman as an outpatient.
The hearing, in Manchester, was told he was made aware she had a 'Dissociative Identity' - a personality disorder - and a 'history of previous satanic ritual abuse' before making a record of it in his notes.
Awakame, who worked in various hospitals in the NHS from 1997 to 2014, will be disciplined next month by the Medical Practitioners Tribunal Service.
He is currently working as a lecturer in 'health informatics' in his home country where he graduated in medicine in 1993.
He studied for a masters degree at the University College of London and a PhD at the University of Leeds.
In an email to the panel he said he had left clinical medicine and added: 'I consider all these proceedings flogging of a dead horse. But I understand the GMC has to go through the motions.'
He said he did not have the 'time or resources' to be involved in the proceedings.'
The situation kind of reminds me of those Yoruba movies where some doctors say "Ę te ese ile bó" translated "seek treatment traditionally." I think Dr. Akwame got his faith and practice mixed up here and may pay dearly for that grievous error.
