The present invention relates to a novel glyceryl phosphoryl choline crystal and a preparation method therefor. With respect to the preparation of the glyceryl phosphoryl choline crystal of the present invention, a novel crystal can be obtained by controlling the crystal precipitation temperature and the stirring time in the solvent environments, and a preparation process is simple compared with a conventional method by not requiring a seeding step. It was ascertained that the crystal of the present invention is a stable solid form in which the melting temperature is 100°C or higher and there is no thermodynamic aging through the analysis result of thermal stability and crystal polymorphism, and thus the crystal is very pharmaceutically useful. In addition, the crystal possesses an excellent hygroscopicity profile from hygroscopicity test results, the bulk density (BD) and the tap density (TD) exhibit values suitable for preparing a dosage form, and the particle distribution degree is very uniform and has symmetric characteristics of a normal distribution, and thus the formulation is simple. The glyceryl phosphoryl choline crystal (form III or IV) of the present invention can be used as a dementia therapeutic agent which is a nootropic agent.La présente invention concerne un nouveau cristal de glycérylphosphorylcholine et son procédé de préparation. Concernant la préparation du cristal de glycérylphosphorylcholine de la présente invention, il est possible dobtenir un nouveau cristal en contrôlant la température de précipitation du cristal et le temps dagitation dans des environnements de solvants, et le procédé de préparation est simple comparativement au procédé conventionnel car il ne nécessite pas détape densemencement. Il a été établi que le cristal de la présente invention se présente sous forme solide stable dans laquelle la température de fusion est supérieure ou égale à 100 °C et quil ny a pas de vieillissement thermodynamique dans le résultat danalyse de la
