The invention relates to medicine, specifically neurology, and can be used to treat patients who have encephalopathy of vascular, traumatic, inflammatory or other origin. In a method for treating encephalopathy by means of drug therapy, according to the invention, a patient's blood glucose level is lowered to 3.4-3.6 mmol/L by intravenous administration of insulin, then solutions of preparations in a single dose are administered intravenously and consecutively with a 30-second interval: first a solution of a vascular preparation having a pharmacological effect, then a solution of a preparation having a direct nootropic effect, then a solution of a peptide preparation and then a solution of a metabolic preparation, wherein one treatment is performed per week, with the total number of treatments being four procedures. In the method for treating encephalopathy, a solution of cavinton or vinpocetine or trental or pentoxifylline is administered as the vascular preparation having a pharmocological effect, a solution of piracetam or nootropil or mexidol or ceraxon is administered as the preparation having a direct nootropic effect, a solution of cortexin or cerebrolysin is administered as the peptide preparation, and a solution of actovegin or solcoseryl is administered as the metabolic preparation. The proposed method for treating encephalopathy provides a stable clinical effect by increasing the nootropic, vasoactive and neurotropic effectiveness of the medicinal preparations administered.L'invention concerne la médecine humaine et notamment la neurologie et peut être utilisée pour traiter les malades souffrant d'encéphalopathie à genèse vasculaire, traumatique, inflammatoire ou autre. Dans cette méthode de traitement d'encéphalopathie par thérapie médicamenteuse on effectue selon l'invention une baisse du taux de glycémie dans le sang du patient jusqu'à 3,4-3,6 mmol/l par l'introduction de l'insuline intraveineuse puis on administre par voie intraveineuse en séquence av
