Urodynamic parameters and bioelectric brain activity were studied in 30 females aged 24-66 years with overactive bladder (OAB) before and after transcranial magnetotherapy. It was found that OAB patients have disorders of bioelectric brain activity by two types of EEG patterns (I.A. Svyatogor classification)--thalamic and stem, Patients with thalamic type EEG benefit more from magnetotherapy higher efficacy of which manifests with regress of clinical symptoms and urodynamic improvement.
