Abstract
The following thesis is based on a series of researches carried out by the author at the London County Mental Hospital, West Park, Epsom, on the drug treatment of the post -encephalitic Parkinsonian state, in a series of 65 cases.
The remedies employed were directed towards the control, and relief, of those distressing manifestations, which follow an attack of encephalitis lethargica, and which form the Parkinsonian syndrome.
The object of this thesis is to draw a comparison between the following drugs : - hyoscine hydrobromide, tincture of stramonium, tincture of belladonna, and genoscopolamine hydrobromate, in their effect on the various manifestations of post-encaphalitic Parkinsonism.
