Mackie J, Ebmeier KP & O'Carroll R (1994) An MRI, SPECT and neuropsychological study of a patient presenting with Capgras syndrome. Behavioural Neurology, 7 (3-4), pp. 211-215.
Describes a young male patient who presented with Capgras syndrome. He underwent detailed neuropsychological, single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI) investigations. Results indicate that the S was of average premorbid intelligence and had a degree of everyday memory dysfunction that was below norms derived from healthy controls, but was average relative to schizophrenic norms. The S demonstrated average or above average recognition memory for patterns, spaces, or words, but a marked and disproportionate impairment in face recognition. The S also demonstrated markedly impaired performance on various tests of executive function. MRI scanning revealed no focal abnormality; slight ventricular dilatation was noted. SPECT scanning, however, revealed marked right/left asymmetries of tracer uptake, restricted to occipital and calcarine cortices.
