- THE LOSS OF FAMILIARITY: A CASE STUDY OF THE COMORBIDITIES OF CAPGRAS AND FREGOLIby Yvonne Flores-Medina on September 27, 2021

She claims that several customers at her shop are her real children. Neuropsychological assessment revealed severe defects in social cognition and an increased number of perseveration responses in the self-directed signaling task. We propose that the latter finding is a measure of the familiarity phenomenon and...

Further, the patient suffered from reduplication of time, scenic hallucinations and psychotic perceptions. Symptoms were the result of a brain metastasis originating from a lung carcinoma. We describe the performed (additional) diagnostics and discuss how to differentiate between organic and functional...
- Incidence and lesions causative of delusional misidentification syndrome after strokeby Yasuro Kakegawa on September 7, 2020
CONCLUSION: The DMS incidence was 1.1% among patients after stroke. All patients had Fregoli syndrome and half had somatoparaphrenia, suggesting that the two syndromes share an underlying pathology. Lesions found with Fregoli syndrome were concentrated around the right uncinate fasciculus; this has not been reported in previous research.
