Are Black Caribbean Patients More Likely to Receive an Incorrect Diagnosis of Very-Late-Onset Schizophrenia-Like Psychosis Than Their White British Counterparts?

Elderly patients with very late-onset schizophrenia-like psychosis and early-onset schizophrenia: Cross-sectional and retrospective clinical findings

“…However, in most studies, negative symptoms were absent in VLOSLP [14,20] while they were present in EOS and to a lesser extent in LOS [14]. Negative symptoms were not at all or barely mentioned in several studies on VLOSLP [18,21,24,26].…”

“…Studies on VLOSLP alone [18][19][20][21][22][23], as well as studies comparing the profile of patients with VLOSLP with that of patients with LOS [14,24,25], elderly EOS [14,24,[26][27][28][29] and healthy controls [30,31] were also realized to better differentially characterize the demographics, clinical symptoms and evolution [14,20,29] of VLOSLP patients.…”

“…In terms of positive symptoms, mild paranoid delusions [14,26] mostly persecutory [18,20,21,24,25], auditory [18,21,25,26] and visual hallucinations [18,21,25], as well as all the Scale for the Assessment of Positive Symptoms (SAPS) [32] behavioral disturbances except for psychomotor abnormalities [25] were described in VLOSLP. These symptoms were sometimes as common as in LOS [25].…”

“…The presence of negative symptoms was also very controversial [14,20,21,25]. In a previous study realized by our team [25], both VLOSLP and LOS patients presented with several negative symptoms as measured by the Scale for the Assessment of Negative Symptoms (SANS) [33]; only apathy was more frequent in LOS than in VLOSLP.…”

“…Les taux de schizophrénie chez les migrants âgés semblent aussi être augmentés, suggérant que le risque élevé persiste tout au long de la vie [28].…”
