An immunosorbent for use in the diagnosis of neuro-psychological disorders comprises a carrier to which is attached a fragment of the receptor proteins from a mammalian brain, said fragment having a molecular mass of 2-45 kD in a quantity of 2-50 nM. The method of diagnosis of neuro-psychological disorders involves the creation for each nosological form (namely, epilepsy, parkinsonism, drug addiction, schizophrenia and Alzheimer's disease) of test systems containing the proposed immunosorbent and monoclonal antibodies representing specific immunoglobulins capable of interacting with the corresponding receptor fragments.
