Objective: The aim of this research was to investigate the prevention, diagnosis, and treatment of patients after COVID-19 with the possibility of using artificial intelligence and virtual reality in combination with traditional approaches to patient rehabilitation., Materials and Methods: Statistical methods were used to evaluate the situation of COVID-19 worldwide and in Slovakia until March 2022. We investigated the rehabilitation options of breathing exercises, upper and lower limb rehabilitation, and cognitive tasks in patients with post-COVID syndrome who met the criteria for a combined rehabilitation program using virtual reality. Using artificial intelligence, we can predict in advance the evolution of the pandemic according to the records of infected patients and the evolution of the pandemic in the world, taking into account nearby territories. In the treatment of post-COVID syndrome, parameters have been identified that can be measured to objectively assess the improvement of the patient's condition and to continue personalizing individual rehabilitation scenarios., Results: In the patients who underwent the combined rehabilitation method, we observed progress in their ability to improve breathing, limb motor skills and also cognitive function of the patients. We identified different categories of parameters that can be evaluated by artificial intelligence methods, and we evaluated different scenarios using the exterior of nature and the interior of the room of the rehabilitation method of virtual reality, as well as the key elements of the "WOW" effect creating emotional changes in the patient for their motivation., Conclusion: We showed that artificial intelligence and virtual reality methods have the potential to accelerate rehabilitation and increase motivation in patients with post-COVID syndrome.

Objectives: The beneficial effects of ozone therapy consist mainly of the promotion of blood circulation: peripheral and central ischemia, immunomodulatory effect, energy boost, regenerative and reparative properties, and correction of chronic oxidative stress. Ozone therapy increases interest in new neuroprotective strategies that may represent therapeutic targets for minimizing the effects of oxidative stress., Methods: The overview examines the latest literature in neurological pathologies treated with ozone therapy as well as our own experience with ozone therapy. The effectiveness of treatments is connected to the ability of ozone therapy to reactivate the antioxidant system to address oxidative stress for chronic neurodegenerative diseases, strokes, and other pathologies. Application options include large and small autohemotherapy, intramuscular application, intra-articular, intradiscal, paravertebral and epidural, non-invasive rectal, transdermal, mucosal, or ozonated oils and ointments. The combination of different types of ozone therapy stimulates the benefits of the effects of ozone., Results: Clinical studies on O2-O3 therapy have been shown to be efficient in the treatment of neurological degenerative disorders, multiple sclerosis, cardiovascular, peripheral vascular, orthopedic, gastrointestinal and genitourinary pathologies, fibromyalgia, skin diseases/wound healing, diabetes/ulcers, infectious diseases, and lung diseases, including the pandemic disease caused by the COVID-19 coronavirus., Conclusion: Ozone therapy is a relatively fast administration of ozone gas. When the correct dose is administered, no side effects occur. Further clinical and experimental studies will be needed to determine the optimal administration schedule and to evaluate the combination of ozone therapy with other therapies to increase the effectiveness of treatment.

Objectives: The aim of the survey was to find out what the possible consequences are of the COVID-19 disease on the nervous system and to propose a method of using artificial intelligence., Material and Methods: Recent research has shown that the risks to patients due to severe acute coronavirus 2 respiratory syndrome (SARS-COV-2) differ most significantly depending on age and the presence of underlying comorbidities such as: cardiovascular disease, hypertension, diabetes and others. The consequences of COVID-19 on the nervous system are especially important. We performed a detailed selection of articles describing the effects of COVID-19 on the nervous system., Results: We made a clear summary of the main consequences of COVID-19 on the nervous system and suggested a way to use artificial intelligence., Conclusion: We confirmed research that artificial intelligence methods have the potential to accelerate prediction, especially for the possible consequences of COVID-19 on the nervous system.

Objectives: The aim of the research was to verify the possibilities of using virtual reality in combination with classical approaches to the rehabilitation of patients after stroke., Material and Methods: As part of rehabilitation, we examined the possibilities of rehabilitation of the upper, lower limbs and fine mobility of the upper limbs in a selected group of patients that met the criteria for inclusion in a combined rehabilitation program using virtual reality with a focus on testing different approaches, devices and applications. At the same time, we tried to identify quantitative and qualitative parameters that could be objectively measured and based on them to evaluate the progress of patients in rehabilitation or in personalizing individual rehabilitation scenarios., Results: In patients who underwent a combined method of rehabilitation, we observed progress in the development of their ability to improve motor skills. We identified various categories of parameters that can be evaluated by artificial intelligence methods, and we also identified that the key elements in the use of virtual reality as a rehabilitation method are the so-called "WOW" effect and the creation of an emotional change in the patient that motivates him to rehabilitate., Conclusion: We have shown that virtual reality methods have the potential to accelerate rehabilitation and increase the motivation of selected groups of patients after stroke.

Objective: One day session linear accelerator based stereotactic radiosurgery of intraocular malignant melanoma is a method of "conservative" attitude to treat posterior uveal melanoma., Material and Methods: Retrospective clinic-based study of patients with posterior uveal melanoma in stage T2/T3 who underwent stereotactic radiosurgery at linear accelerator in period 2001-2011. Immobilization of the affected eye was achieved by mechanical fixation to the stereotactic Leibinger frame. The stereotactic treatment planning after fusion of computed tomography and magnetic resonance imaging was optimized according to the critical structures (lenses, optic nerves, chiasm)., Results: In group of 96 patients with posterior uveal melanoma treated with one day session stereotactic radiosurgery, patient age ranged from 25 to 80 years with a median of 54 years. Median tumor volume at baseline was 0.6 cm(3) (with range from 0.2 to 1.0 cm(3)). Median maximal dose applied was 49.0 Gy (range from 37.0 to 52.0 Gy). Secondary enucleation was necessary in 11 patients (11.5%) due to complications like irradiation neuropathy and secondary glaucoma. Tumor local control was successful in 95% of patients in 3 years interval after stereotactic radiosurgery and in 85% of patients in 5 years interval after stereotactic radiosurgery., Conclusion: One step LINAC based stereotactic radiosurgery with a single dose 35.0 Gy is one of treatment options to treat T2 or T3 stage posterior uveal melanoma.

Objective: Epilepsy can be considered as a result of the imbalance of the excitatory and inhibitory processes. Therefore, the artificial enhancement of the activity of brain inhibitory mechanisms might lead to a beneficial therapeutic effect for intractable epilepsy patients., Material and Methods: Studies of the inhibitory effects of electrical stimulation of the head of the caudate nucleus (HCN), cerebellar dentate nucleus (CDN), thalamic centromedian nucleus (CM), and neocortical and temporal lobe mesiobasal epileptic foci were performed on 150 patients with implanted intracerebral electrodes. Chronic brain stimulation with implanted neurostimulators was performed on 54 patients. Sixteen were followed up to 1.5 years (mean 1.2 years)., Results: The study demonstrated that 4-8 Hz HCN and 50-100 Hz CDN stimulation suppressed the subclinical epileptic discharges and reduced the frequency of generalized, complex partial, and secondary generalized seizures. CM stimulation (20-130 Hz) desynchronized the EEG and suppressed partial motor seizures. Direct subthreshold 1-3 Hz stimulation of the epileptic focus may suppress rhythmic afterdischarges (ADs). Seizures were eliminated for 26 of 54 patients (48%), worthwhile improvement was achieved for 23 of 54 patients (43%), and no improvement was observed in 5 of 54 patients (9%)., Conclusion: The artificial increase of the activity of brain inhibitory system may suppress the activity of epileptic foci, and, in long run, stabilize this epileptic foci activity at a lower, perhaps normal, level. Therapeutic direct brain stimulation, therefore, might serve as a useful tool in the treatment of intractable and multifocal epilepsy, and might be combined with ablative surgical methods.
