Heterogeneity in schizophrenia; mixture modelling of age‐at‐first‐admission, gender and diagnosis

Abstract

Our findings suggest that subtypes based on age-at-first-admission can be identified, although the number identified depends on how inclusively schizophrenia is defined. While there appear to be the same number with similar mean ages for both genders, there are differences in the proportions of males to females. Further work to fully characterize their nature is warranted.
