COVID-19 is increasingly being linked to brain health impacts. The emerging situation is consistent with evidence of immunological injury to the brain, which has been described as a resulting “brain fog.” The situation need not be medicalized but rather clinically managed in terms of improving resilience for an over-stressed nervous system. Pre-existing comparisons include managing post-concussion syndromes and/or brain fog. The objective evaluation of changes in cognitive functioning will be an important clinical starting point, which is being accelerated through pandemic digital health innovations. Pre-morbid brain health can significantly optimize risk factors and existing clinical frameworks provide useful guidance in managing over-stressed COVID-19 nervous systems.

It was identified on the base of special periodical literature analyze that cyclic muscular work systematically performed during large part of the person's life (former athlete) provides mainly the favorable effect on the brain. Ventricular-arterial coupling improvement ameliorates brain perfusion, and creates function advantages to brain health in old age. At that, the gray and white matter fading hampered, especially in structures that associated with visual control and human body spatial orientation, motor control and memory state, and age-related attenuation of cognitive functions in comparison with sedentary persons of the same age.

Neurosurgery describes the surgical treatment and management of various disease processes that target the brain, spinal cord, and peripheral nervous system. The specialty is wide and varied as increasing numbers of neurological conditions can now be improved following neurosurgery; for example, some types of epilepsy respond to the insertion of a vagal nerve stimulator, Parkinson’s disease symptoms can be diminished with a deep brain stimulator, and intractable back pain may be improved following spinal surgery. Practitioners must be equipped with the knowledge and skills to care for these patients and meet their immediate and long-term needs.

AbstractAutoimmune diseases of the nervous system in children are composed of a heterogeneous group of rare disorders that can affect the central or peripheral nervous system at any level. Presentations may occur in children of any age and are typically acute or subacute in onset. Consideration of an autoimmune process as the etiology of neurologic diseases in children is important, as it may lead to early initiation of immunotherapy and an improvement in long-term neurologic outcomes. The developing nervous and immune systems in children create unique challenges in diagnosis and treatment of these rare diseases. In this review, autoimmune diseases affecting the brain, spinal cord, nerve roots, peripheral nerves, neuromuscular junction, and muscle in children are described.

AbstractA delirium in patients in the intensive care unit (ICU) is a manifestation of a severe acute dysfunction of the brain. It has a high prevalence and is associated with a relevant increase in morbidity and mortality. A cholinergic deficit and dopaminergic overactivity are considered to be a cause of delirium. Polypharmacy, which is often present before admission to the ICU, especially in the elderly, plays a key role as a trigger. The knowledge and identification of risk factors for delirium is a precondition for the early and effective prevention of delirium. The aim is the pre-operative or pre-interventional optimization of modifiable risk factors. Early and effective prevention of delirium can improve clinical outcome, reduce mortality, and positively impact long-term functional outcome. Non-pharmacological measures are always the basis for the prevention of delirium: maintenance of the day-night rhythm, sleep promotion at night and stimulation during the day, involvement of relatives, the avoidance of dehydration and malnutrition, and others more. They are pharmacologically accompanied by an effective analgesia and a target and symptom-oriented sedation with well controllable, as little as possible delirogenic substances. Interdisciplinary and interprofessional cooperation is essential so that preventive concepts significantly reduce the risk of delirium, even in high-risk patients.

The purpose of our research was to estimate the brain blood supply level by rheoencephalography method in junior students of the Medical academy and to determine the blood supply links with the autonomic regulation state, behavioural and alimentary factors. Rheo-encephalographic study, research of the autonomic nervous system state, heart rate regulation and questioning of 17–29 year-old students have been conducted. Basic hemodynamic indices were normal in all surveyed students. Increase in body weight index enhanced the probability of the brain blood supply deterioration. Adaptation mechanisms tension was accompanied by reduction of the rheographic index. Higher blood filling of the brain vessels corersponded to higher ratio “blood minute volume / due blood minute volume” defined taking into account the system arterial pressure. The quantity of links with indicators of the autonomic nervous system state was limited. Nonlinear dependence of the rheographic index on the Kerdo vegetative index was observed: the rheographic index value was the lowest in students with the autonomic balance by the Kerdo vegetative index; it was the highest in the group with the sympathetic prevalence. Risk factor of blood filling decrease was the reduction in the diet variety when foodstuffs of different groups were included into the diet less than twice a week, or they were excluded from the diet completely. Positive correlation of blood supply was observed more often with frequent consumption of fish, vegetables, and fresh fruits. Increase in the regular alcohol intake experience promoted decrease in brain blood supply and increase in asymmetries of blood supply indicators. The effect of alcohol was essential, despite young age of surveyed students and low level of alcohol consumption. Increase in the experience and intensity of smoking was accompanied by deterioration of brain blood supply indicators. Students with the best blood supply had the better academic progress. Observed multiple correlations of blood supply indicators with behavioural factors allowed to assert that reduction of risk factors (control of body weight, variety and full value of a diet, refusal of smoking, alcohol restriction even below doses which are considered safe) would allow to improve the brain blood supply.

Abstract Purpose The aim of this retrospective analysis is to estimate the most appropriate single cycle and cumulative doses of 225Ac-DOTATOC in patients treated for somatostatin-receptor-expressing cancers. Methods 225Ac-DOTATOC was administered to thirty-nine patients with various somatostatin-receptor-positive tumors. Baseline and follow-up 68Ga-DOTATOC PET/CT, lab tests, and renal scintigraphy were obtained. Patients received long-term follow-up either at the local cancer center or in close collaboration with external oncologists. Acute and chronic hematological toxicity was evaluated quantitatively over time. Long-term follow-up of creatinine was used to approximate the annual loss of estimated GFR (eGFR). Results Dose-dependent acute hematological toxicity was seen at single doses above 40 MBq or repeated doses greater than approximately 20 MBq 225Ac-DOTATOC at 4 month intervals. Treatment-related kidney failure occurred in 2 patients after a delay of >4 years but was independent of administered radioactivity, and other clinical risk factors were important contributors to renal decline. In general, the annual decline of eGFR among patients did not follow a clear dose-effect relationship even in patients with previous β-therapy. An average eGFR-loss of 8.4ml/min (9.9%) per year was observed which is similar to the experience with β-therapy studies. Conclusion Treatment activities of approx. 20 MBq per cycle (4 monthly repetition) and cumulative doses up to 60–80 MBq generally avoided both acute and chronic grade 3/4 hematotoxicity in patients with advanced stage malignancies. Chronic renal toxicity was observed at these doses, but pre-existing renal risk factors were important co-factors. These data represent a starting point for additional research to more precisely define safety thresholds of 225Ac-DOTATOC.

When SARS-CoV-2 began to spread, older adults experienced disproportionately greater adverse effects from the pandemic, including exacerbation of pre-existing physical and cognitive frailty conditions. More severe complications, higher mortality, and concerns about disruptions to their daily routines and access to care. Knowledge about the impact of COVID-19 on the brain is rapidly accumulating and this is reflected in the increasing use of the term “neurocovid”. Co-involvement of the central and peripheral nervous system had already been observed in SARS patients, but COVID-19 seems to invade it with greater affinity than other coronaviruses. This chapter provides an overview of the expanding understanding of the multiple ways in which COVID-19 affects the human brain, discuss the likelihood of long-term sequelae of neurocovid, and their implications for cognitive functions and behaviors in the elderly.

Coronavirus infection is a systemic pathology resulting in impairment of the nervous system. The involvement of the central nervous system in COVID-19 is diverse by clinical manifestations and main mechanisms. The mechanisms of interrelations between SARS-CoV-2 and the nervous system include a direct virus-induced lesion of the central nervous system, inflammatory-mediated impairment, thrombus burden, and impairment caused by hypoxia and homeostasis. Due to the multi-factor mechanisms (viral, immune, hypoxic, hypercoagulation), the SARS-CoV-2 infection can cause a wide range of neurological disorders involving both the central and peripheral nervous system and end organs. Dizziness, headache, altered level of consciousness, acute cerebrovascular diseases, hypogeusia, hyposmia, peripheral neuropathies, sleep disorders, delirium, neuralgia, myalgia are the most common signs. The structural and functional changes in various organs and systems and many neurological symptoms are determined to persist after COVID-19. Regardless of the numerous clinical reports about the neurological and psychiatric symptoms of COVID-19 as before it is difficult to determine if they are associated with the direct or indirect impact of viral infection or they are secondary to hypoxia, sepsis, cytokine reaction, and multiple organ failure. Penetrated the brain, COVID-19 can impact the other organs and systems and the body in general. Given the mechanisms of impairment, the survivors after COVID-19 with the infection penetrated the brain are more susceptible to more serious diseases such as Parkinson’s disease, cognitive decline, multiple sclerosis, and other autoimmune diseases. Given the multi-factor pathogenesis of COVID-19 resulting in long-term persistence of the clinical symptoms due to impaired neuroplasticity and neurogenesis followed by cholinergic deficiency, the usage of Neuroxon® 1000 mg a day with twice-day dosing for 30 days. Also, a long-term follow-up and control over the COVID-19 patients are recommended for the prophylaxis, timely determination, and correction of long-term complications.

Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory disorder of the central nervous system (CNS) that can be fatal or lead to long-term disability. Various triggers have been identified in children and adults, which presumably cause an autoimmune response targeting myelin. The resulting inflammation causes demyelination and edema of the brain, spinal cord, and optic nerves. Depending on which portion of the CNS is affected, patients will experience a variety of symptoms including weakness, numbness, ataxia, encephalopathy, and seizures. Treatment is currently focused on reducing the amount of inflammation and supportive care.

Cognitive Changes

There is robust evidence linking vascular health to brain health, cognition, and dementia. In this article, we present evidence from trials of vascular risk factor treatment on cognitive outcomes. We summarize findings from randomized controlled trials of antihypertensives, lipid-lowering medications, diabetes treatments (including antidiabetic drugs versus placebo, and intensive versus standard glycemic control), and multidomain interventions (that target several domains simultaneously such as control of vascular and metabolic factors, nutrition, physical activity, and cognitive stimulation etc). We report that evidence on the efficacy of vascular risk reduction interventions is promising, but not yet conclusive, and several methodological limitations hamper interpretation. Evidence mainly comes from high-income countries and, as cognition and dementia have not been the primary outcomes of many trials, evaluation of cognitive changes have often been limited. As the cognitive aging process occurs over decades, it is unclear whether treatment during the late-life window is optimal for dementia prevention, yet older individuals have been the target of most trials thus far. Further, many trials have not been powered to explore interactions with modifiers such as age, race, and apolipoprotein E, even though sub-analyses from some trials indicate that the success of interventions differs depending on patient characteristics. Due to the complex multifactorial etiology of dementia, and variations in risk factors between individuals, multidomain interventions targeting several risk factors and mechanisms are likely to be needed and the long-term sustainability of preventive interventions will require personalized approaches that could be facilitated by digital health tools. This is especially relevant during the coronavirus disease 2019 (COVID-19) pandemic, where intervention strategies will need to be adapted to the new normal, when face-to-face engagement with participants is limited and public health measures may create changes in lifestyle that affect individuals’ vascular risk profiles and subsequent risk of cognitive decline.
