While some have sought to interpret, if in a qualified fashion, the use by Morel of the term "démence précoce" as amounting to the "discovery" of schizophrenia, others have argued convincingly that Morel's descriptive use of the term should not be considered in any sense as a precursor to Kraepelin's dementia praecox disease concept. This is due to the fact that their concepts of dementia differed significantly from each other, with Kraepelin employing the more modern sense of the word and that Morel was not describing a diagnostic category. Indeed, until the advent of Pick and Kraepelin, Morel's term had vanished without a trace and there is little evidence to suggest that either Pick or indeed Kraepelin were even aware of Morel's use of the term until long after they had published their own disease concepts bearing the same name. As Eugène Minkowski succinctly stated, 'An abyss separates Morel's démence précoce from that of Kraepelin.'
