 Neuropsychological accounts of delusions offer very satisfactory accounts of some delusions, as one can often identify with some precision the damaged region of the brain and the causal link between the damage and its psychological manifestations, culminating with the formation of the delusion. Neuropsychological accounts of other delusions – once regarded as ‘functional’ – are also being developed and explored. For some delusions, hybrid accounts have been proposed, where a combination of different factors (including motivation) significantly contribute to the formation of the delusion (e.g. McKay et al. 2007). One such case seems to be the Reverse Othello Syndrome, the delusion that a romantic partner is still faithful to us when this is no longer the case. The belief can be regarded as a defense against the suffering that the acknowledgement of the infidelity of our partner would cause (see example in Butler 2000 as cited and discussed by McKay et al. 2005a, p. 313).
