Schizophrenia, like autism, is a blanket term. Eugen Bleuler, who coined the word in 1908, actually referred to schizophrenias. In 1972, the eminent neurologist Frederick Plum famously said, “Schizophrenia is the graveyard of neuropathologists,” meaning that no one had understood or would understand its etiology. We now understand more of schizophrenia than we do of autism. It is unclear whether schizophrenia should be subtyped according to biology (genotype) or behavior (phenotype).
