Is late‐onset schizophrenia a subtype of schizophrenia?
Open accessAbstract
Vahia IV, Palmer BW, Depp C, Fellows I, Golshan S, Kraemer HC, Jeste DV. Is late‐onset schizophrenia a subtype of schizophrenia? Objective: To determine whether late‐onset schizophrenia (LOS, onset after age 40) should be considered a distinct subtype of schizophrenia. Method: Participants included 359 normal comparison subjects (NCs) and 854 schizophrenia out‐patients age >40 (110 LOS, 744 early‐onset schizophrenia or EOS). Assessments included standardized measures of psychopathology, neurocognition, and functioning. Results: Early‐onset schizophrenia and LOS groups differed from NCs on all measures of psychopathology and functioning, and most cognitive tests. Early‐onset schizophrenia and LOS groups had similar education, severity of depressive, negative, and deficit symptoms, crystallized knowledge, and auditory working memory, but LOS patients included more women and married individuals, had less severe positive symptoms and general psychopathology, and better processing speed, abstraction, verbal memory, and everyday functioning, and were on lower antipsychotic doses. Most EOS–LOS differences remained significant after adjusting for age, gender, severity of negative or deficit symptoms, and duration of illness. Conclusion: Late‐onset schizophrenia should be considered a subtype of schizophrenia.

In the citing paper
“Late‐onset schizophrenia appeared to be as stable a diagnosis as early‐onset schizophrenia; both diagnoses remained unchanged in up to 93% of cases in a follow‐up, and only rarely were they reclassified as mood disorders263, 264.”

In the citing paper
“Sensory deficits, especially long‐standing conductive deafness, are common in the late‐onset form 264 , but may primarily reflect the patients' reluctance to seek corrective measures or their inability to get correction of these deficits because of poor access to quality health care.”

“The difference in processing speed was particularly surprising as the LOS group was, on average, 6 years older than the EOS group, and processing speed tends to decline steadily with normal aging (86).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
