The neuropsychology and neurobiology of late-onset schizophrenia and very-late-onset schizophrenia-like psychosis: A critical review

Abstract: Multiple changes in neurobiology and cognition contributing to LOS/VLOSLP may reflect stress-related accelerated brain aging rather than neurodegenerative pathology. Their involvement in the onset of illness, however, might be inversely proportional to pre-existing (psychosocial and/or genetic) vulnerability to psychosis.

“…As schizophrenia patients' longevity increases and because higher cognitive deficits increase the risk of dementia (Van Assche, Morrens, Luyten, Van de Ven, & Vandenbulcke, 2017), it is important to adapt remediation programs to the specificity of older patients. Improving cognition in these patients may have several benefits such as higher quality of life, autonomy and perhaps preventing from dementia.…”

“…Interestingly, the onset of both delusions and hallucinations in late life reflects disturbances in the frontal-subcortical-temporal brain systems transdiagnostically (Holt & Albert, 2006). Indeed, schizophrenia-like illnesses in late life are associated with increased ventricle-to-brain ratio (VBR), white matter (WM) pathology as well as functional and structural abnormalities in the frontal, subcortical and temporal brain regions compared to normally aging individuals (Van Assche et al, 2017). Additionally, frontotemporal abnormalities in the most frequently occurring neurodegenerative conditions in late life such as AD or DLB with psychotic symptoms also supersede those observed in AD or DLB without such symptoms (Jellinger, 2012).…”

“…The first onset of psychosis in late life is more common than previously assumed (Fischer & Aguera-Ortiz, 2017), presenting in approximately 10 to 62% of nursing home residents, 5 to 15% of elderly psychiatric inpatients and 27% of psychiatric outpatients (Reinhardt & Cohen, 2015). Many of these older individuals exhibit psychosis as a prodromal symptom to dementia (Kørner, Lopez, Lauritzen, Andersen, & Kessing, 2009;Savva et al, 2009), often associated with Alzheimer's type Dementia (AD) or Dementia with Lewy Bodies (DLB) (Van Assche, Morrens, Luyten, Van de Ven, & Vandenbulcke, 2017). However, in more than half of these cases, there is a non-progressive mild cognitive deficit (Brodaty, Sachdev, Koschera, Monk, & Cullen, 2003).…”

“…Accordingly, Brodaty suggests LOS predicts dementia in half of the cases [44]. Progressive cognitive decline seems to be related with stress-related accelerated brain aging rather than a neurodegenerative pathology [45].…”
