Traumatic trigeminal neuropathy occupies a special place in the pain continuum. The clarification of genesis and clinical and neurophysiological findings makes it possible to perform differentiation treatment.Objective: to evaluate the clinical and neurophysiological efficiency of repetitive magnetic stimulation (RMS) and vitamin B complex therapy for traumatic trigeminal neuropathy.Patients and methods. The investigation enrolled 36 patients (26 women and 10 men) aged 25 to 35 years with inferior alveolar neuropathy following bilateral sagittal split osteotomy. The DN4 questionnaire was used to identify a neurogenic pain component. The intensity of pain syndrome was assessed using a visual analogue scale. A neurophysiological examination involving the recording of brainstem auditory evoked potentials (BAEPs) and trigeminal evoked potentials (TEPs) was made using a Neuro-MEP device (Neurosoft, Russia). Therapy including vitamin B complex was performed in 12 patients. Twenty-four patients received low-frequency pulsed magnetic field therapy using a Neuro-MS magnetic stimulator.Results and discussion. The clinical picture in patients with traumatic inferior alveolar neuropathy after corrective mandible surgery is characterized by the polymorphism of pain sensations and sensory disorders. The development of pain syndrome is due to a neuropathic component. The 10-day vitamin group B therapy cycle had no substantial impact on the time course of clinical and neurophysiological changes. After the 10-day RMS cycle, there were reductions in swelling and the intensity of pain syndrome and the severity of sensory disorders in the lower lip, chin, and mandible. The data on BAEPs showed shortening in the interpeak intervals III–V; those on TEPs demonstrated a decrease in the P1–N1 amplitude.Conclusion. Unlike vitamin B complex therapy, the RMS cycle in patients with traumatic trigeminal neuropathy makes it possible to reduce the intensity of pain syndrome and the severity of sensory disorders, as well as excitability of the nonspecific structures of the brainstem and the central structures of the trigeminal system.

Background. Type 2 diabetes (Т2DM) both directly and indirectly impacts the development of morphological and functional changes of the central nervous system. Aim. The study was to determine clinical and neurophysiological patterns of cognitive impairment (CI) in patients with chronic cerebrovascular diseases (CCD) and Т2DM. Materials and methods. We examined 132 patients with CCD. First group included 58 patients without Т2DM aged 64.5 [58; 72], second group 74 patients with CCD and Т2DM 63 [57; 70]. Clinical, neurological, neuropsychological, neurophysiological (cognitive evoked potentials (EP) and neurovisualisation (brain MRI) examination was carried out to all patients. Results. Somatic and neurological characteristics of the patients were similar in both groups with the exception of more distinct metabolic changes in Т2DM patients. Neurovisualisation study of the brain MRI in Т2DM patients revealed more distinct changes in the form of white matter hyperintensity and subarachnoidal spaces enlargement. Neuropsychological examination in patients revealed the reduction of intellectual flexibility, constructive praxis disruption, optical spatial dysfunction and deteoration of delayed word recall. Significant disorders in the way of overall cognitive impairment, lobar dysfunction and impaired verbal associative productivity, proved by statistically lower amplitude and higher latency of P300 EP peak were noted in Т2DM patients. Correlation links were detected: for P300 amplitude and direct and inverse number listing test (r=0.366 and r=0.520; p=0.006 and p0.001 respectively); P300 latency and HbA1c (r=0.32; р0.05) in group 2 and glucose levels in both groups (r=0.30; p0.05); inverse relationship of latency with control functions evaluation (r=-0.34; p=0.008). Conclusion. CCD especially with Т2DM manifests with neurocognitive imbalance, including control functions disruption and are accompanied by neurophysiological and neurovisualistion changes.
