The present invention relates to the medical field, in particular to the treatment of neurological disorders. More specifically the present invention relates to a nanoparticle or nanoparticles' aggregate for use in prevention or treatment of a neurological disease or at least one symptom thereof in a subject when the nanoparticle or nanoparticles' aggregate is exposed to an electric field, wherein the nanoparticle's or nanoparticles' aggregate's material is selected from a conductor material, a semiconductor material, an insulator material with a dielectric constant εijk equal to or above 200, and an insulator material with a dielectric constant εijk equal to or below 100. It further relates to compositions and kits comprising such nanoparticles and/or nanoparticles' aggregates as well as to uses thereof.
