FIELD: medicine.
SUBSTANCE: use of a nanoparticle or an aggregate of nanoparticles and a composition based on them for improvement of training, memorizing, and attention in a subject is disclosed, where material of the nanoparticle or the aggregate of nanoparticles is selected from conductive material selected from Tl, Po, Ag, Pd, Ir, Pt, and/or Au, and organic material having adjacent sp2-hybridized carbon centers in its structure, and insulation material selected from La2O3, SiO2, SnO2, Ta2O5, ReO2, ZrO2, HfO2, Y2O3, and diamond-like carbon, where i) a median size of a core of the nanoparticle or the aggregate of nanoparticles of a population is at least 30 nm, when material is conductive material, where ii) the core of the nanoparticle or the aggregate of nanoparticles is covered with biocompatible coating providing a negative surface charge, where iii) nanoparticles or aggregates of nanoparticles are not used as a carrier of a therapeutic compound or a drug, and where iv) biocompatible coating providing the negative surface charge is selected from phosphate, dicarboxylic acid, succinic acid, or sulphate. The use of the above-described nanoparticles or the aggregate of nanoparticles and the composition based on them for the treatment of at least one symptom of pathological stress is also disclosed.
EFFECT: group of inventions provides treatment of diseases and improvement of conditions without impact on a nanoparticle or an aggregate of nanoparticles of an electric field or any other external activation source.
