Fifteen years ago the late Professor Korsakow described an assemblage of symptoms met with most frequently amongst chronic alcoholics. He claimed that they represented a distinct disease, which he termed polyneuritic psychosis, and later cerebropathia psychica toxæmica. The cardinal features of this affection, according to him, were, besides the polyneuritis, amnesia and pseudo-reminiscence. We in England, perhaps wisely, are slow to accept new diseases; but as now a large amount of literature has accumulated around “Korsakow's disease” from physicians in all parts of Europe, it may be of interest to give an account of twelve cases among women which I have met with presenting the symptoms of this affection.
