Evaluation of a psychoeducation group for children presenting with functional tic-like behaviours.

We describe the implementation and evaluation of an online psychoeducation group for young people experiencing functional tic-like behaviours (FTLBs) - a type of functional neurological disorder (FND). Across six groups, 50 participants completed pre- and post-group goal-based outcomes (GBOs) and 36 participants completed service-user feedback, which gathered qualitative and quantitative data about participants experiences of the group. Young people and their parents reported significant improvement in their GBOs following the group and increased knowledge and confidence in managing FTLBs. The findings highlight that virtual psychoeducation group intervention is an acceptable and effective first step in treatment of young people with FTLBs. We discuss implications for future intervention development.

From Hysteria to Functional Neurological Symptom Disorder: Developments in Clinical Diagnosis and Neurobiology

Changes in the nomenclature of functional neurological symptom disorders (FND) from the past to the present represent historical changes in understanding etiology. Today, there is still difficulty in excluding potential underlying neurological disorders. In addition, there is no consensus on the psychological mechanism leading to the disorder. As a result, diagnostic problems continue to exist. While functional neuroimaging studies show that suppression and conversion mechanisms, which are the concepts of the psychoanalytical theory, may have neural counterparts, neurobiological data suggests that the conversion model cannot be explanatory for every patient. The dorsolateral prefrontal cortex (dlPFC), amygdala, temporoparietal junction (TPJ), insula, anterior cingulate structures, and their connections come to the fore. The fact that the connections between the dlPFC and the hippocampus can prevent the recall of an unwanted memory, as well as the changes detected in the amygdala in these disorders and the increased connectivity between the amygdala and the motor areas, suggest an abnormal connection between emotions and the motor system. It is addressed how changes in the TPJ are related to the loss of the sense of agency. However, it is unclear whether the findings of these studies suggest a "predisposition", "onset of disorder", or "compensatory changes secondary to disorder". Exploring FND to learn how the brain and mind react to psychosocial stressors can be a turning point in understanding the brain-mind connection. The goal of this review is to present the history of the changes in terminology and perspective on this disorder that followed the establishment of psychoanalysis, as well as what kind of evidence has been presented regarding hysteria in light of advances in neuroscience

ОСОБЕННОСТИ НУТРИТИВНОГО СТАТУСА ДЕТЕЙ С МУКОВИСЦИДОЗОМ РАЗЛИЧНЫХ ЭТНИЧЕСКИХ ГРУПП СЕВЕРНОГО КАВКАЗА

Adequate nutritional status in a patient with cystic fibrosis (CF) positively correlates with the normal function of the bronchopulmonary system. Many domestic and foreign studies have been conducted so far to assess the nutritional status of children and adults with CF. However, there is no data as yet on the phenotypic characteristics of children from different ethnic groups of the North Caucasus depending on their genotype. The purpose of this research was to study the peculiarities of nutritional status in children with CF of the following Russia’s North Caucasus ethnic groups: Chechen, Karachay-Circassian, Dagestani, Ingush and Ossetian-Alanian. Materials and methods used: a single-center open prospective study of 117 children with CF aged 2 months to 17 years old (Me 6 y/o) of various North Caucasus ethnic groups was conducted. All patients have undergone molecular diagnosis and assessment of both nutritional status and exocrine pancreatic function. Results: 50.4% of pediatric patients with CF in the Russia’s North Caucasus have had pathological mutations in c.1545_1546delTA, p.(Tyr515*) and c.3846G>A, p.(Trp1282*) in homozygous state. These mutations were most often found in the Ingush (100%) and Chechen (82%) ethnic groups and somewhat less frequently in the Dagestani (57.1%) and Karachay-Circassian (54%) ethnic groups. In the Chechen and Ossetian-Alanian ethnic groups, when these mutations were detected, severe pancreatic insufficiency was established in 40.5% and 100% of cases, respectively. Pseudo-Bartter syndrome was diagnosed in 60% of cases with this genetic variant in a homozygous or compound heterozygous states during the patients’ first years of life. Indicators for the nutritional status of children with CF from different ethnic groups were significantly lower compared to those recorded officially in the 2021 Russian National Register of Patients with CF. Conclusion: it is necessary to study the course of CF and the state of nutritional status separately in each population and its connection with the identified genetic characteristics of the Russia’s North Caucasus ethnic groups. The genotype and phenotype patterns for these patients were the reason for the development of disorders of the exocrine function of the pancreas and pseudo-Bartter syndrome at an early age, which in its turn could lead to further development of nutritional deficiency.

Illness perceptions, experiences of stigma and engagement in functional neurological disorder (FND): exploring the role of multidisciplinary group education sessions

BackgroundA critical first step in managing functional neurological disorder (FND) is a positive diagnosis and clear explanation using an understandable illness model. Multidisciplinary group education sessions are one way to...

The Last Straw: How Stress Can Unmask Parkinson's Disease.

We discuss two people with Parkinson's disease (PD), in whom tremor manifested directly following a severely stressful event. Both were initially misdiagnosed with a functional neurological disorder. These stories highlight that stress can trigger the onset of clinical manifestations of PD, by unveiling an underlying disease that had been unfolding for many years. Thus, the sudden symptom onset after a stressful event is not unique to functional disorders, and may lead to avoidable feelings of guilt if people wrongly attribute PD to this event. It remains unclear what mechanism explains this phenomenon, and why symptoms persist after the stressful event has passed.

When the diagnosis is in the patient's hand and in the neurologist's eye.

The objective of this study was to encompass current knowledge about pathophysiological mechanisms of those specific hand postures or deformities caused by central nervous system disorders. In the era of high-resolution neuroimaging and molecular biology, clinicians are progressively losing confidence with neurological examination. Careful hand observation is of key importance in order to differentiate neurological from non-neurological conditions, central from peripheral aetiologies, and organic from functional disorders. Localizing the potential anatomical site is essential to properly conduct subsequent exams. We provided a practical guide for clinicians to recognize hand patterns caused by central nervous system disorders, avoiding mimicking conditions, thus optimizing and prompting the diagnostic pathway.

Development of normal reference intervals for renal function in pregnancy: a secondary analysis of clinical trial data

Background Due to its potential nephrotoxicity, screening for pre-existing renal function disorders has become a routine clinical assessment for initiating Tenofovir diphosphate fumarate (TDF)-containing antiretroviral treatment (ART) or pre-exposure prophylaxis (PrEP) in pregnant and non-pregnant adults. We aimed to establish reference values for commonly used markers of renal function in healthy pregnant women of African origin. Methods Pregnant women ≥18 years, not living with HIV, and at 14–28 weeks gestation were enrolled in a PrEP clinical trial in Durban, South Africa between September 2017 and December 2019. Women were monitored 4-weekly during pregnancy until six months postpartum. We measured maternal weight and serum creatinine (sCr) at each visit and calculated creatinine clearance (CrCl) rates using the Cockcroft–Gault (CG) and Modification of Diet in Renal Disease (MDRD) formulae. Reference ranges for sCr and CrCl by CG and MDRD calculations were derived from the mean ± 2SD of values for pregnancy and postdelivery. Results Between 14-–and 40 weeks gestation, 249 African women not exposed to TDF-PrEP contributed a total of 1193 renal function values. Postdelivery, 207 of these women contributed to 800 renal function values. The normal reference range for sCr was 30–57 and 32–60 umol/l in the 2nd and 3rd trimesters of pregnancy. Normal reference ranges for CrCl using the MDRD calculation were 129–282 and 119–267 ml/min/1.73m2 for the 2nd and 3rd trimesters, respectively. Using the CG method of calculation, normal reference ranges for CrCl were 120—304 and 123–309 ml/min/1.73m2 for the 2nd and 3rd trimesters respectively. In comparison, the normal reference range for sCr, CrCl by MDRD and CG calculations postpartum was 40–77 umol/l, 92–201, and 90–238 ml/min/1.73m2, respectively. Conclusions In African women, the Upper Limit of Normal (ULN) for sCr in pregnancy is approximately 20% lower than 6 months postnatally. Inversely, the Lower Limit of Normal (LLN) for CrCl using either MDRD or CG equation is approximately 35% higher than 6 months postnatally. We provide normal reference ranges for sCr and CrCl for both methods of calculation and appropriate for the 2nd and 3rd trimesters of pregnancy in African women.

Cardiovascular mortality in bipolar disorder: Population-based cohort study.

Limited evidence base on cause-specific excess cardiovascular disease (CVD) mortality in bipolar disorder (BD) is a barrier to developing preventive interventions aimed at reducing the persistent mortality gap in BD. To investigate cause-specific CVD mortality in BD. We identified all individuals aged 15+ years during 2004-2018 with a diagnosis of BD using Finnish nationwide routine data. Standardised mortality ratios (SMR) with 95% confidence intervals (CI) were calculated using the mortality rates in the general population as weights. 53,273 individuals with BD (57% women; median age at BD diagnosis, 40 years), were followed up for 428,426 person-years (median, 8.2 years). There were 5988 deaths due to any cause, of which 26% were due to CVD. The leading cause of absolute excess CVD mortality was coronary artery disease (CAD). The leading causes of relative excess mortality were cardiomegaly (SMR, 4.51; 95% CI, 3.58-5.43), venous thromboembolism (3.03; 2.26-3.81), cardiomyopathy (2.46; 1.95-2.97), and hypertensive heart disease (2.12; 1.71-2.54). The leading causes of absolute CVD mortality showed markedly lower relative excess, including CAD (1.47; 1.34-1.61), ischaemic stroke (1.31; 1.06-1.54), and acute myocardial infarction (1.12; 0.98-1.25). Due to the higher relative excess mortality, structural and functional heart disorders contributed as much as atherosclerotic and ischaemic disorders to the absolute excess mortality. Cardiomyopathy and hypertensive heart disease as the leading causes of relative excess mortality emphasise the contribution of structural and functional heart disorders to the overall excess mortality alongside coronary artery disease. Interventions targeted at these modifiable causes of death should be priorities in the prevention of premature excess CVD mortality in BD.

Clinical and instrumental characteristics of psoriatic arthritis in men and women. Data from a cohort observational study

To study and compare the clinical and imaging characteristics of psoriatic arthritis (PsA) in men and women. The study included 956 PsA patients observed in the Russian register, 411 (43%) men and 545 (57%) women. The average age of men/women was 46.0±16.50/50.7±17.20 years (p<0.001), the duration of PsA was 9.9±6.4/10.3±7.6 years (p>0.05), the age at the time of PsA establishment was 37.1±12.30/41.8±13.5 years (p<0.001). Rheumatological examination, X-ray of the pelvis, hands, feet were performed, the LEI, plantar fascia tenderness, body surface area (BSA), body mass index (BMI), CRP, HLA-B27 were determined. Patients filled out assessment scales of pain (Pain), disease activity (patient global assessment of disease activity - PGA), questionnaires HAQ-DI. The indices of Disease Activity in PSoriatic Arthritis (DAPSA), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), criteria of minimal disease activity (MDA) were evaluated. The following differences in the course of PsA in men/women were revealed: X-ray sacroiliitis was detected in 175 (42.6%)/153 (28.1%); p<0.001; the presence of erosions of the joints of the hands and feet - 138 (33.6%)/170 (31.2%); p=0.435; LEI≥3 - 34 (11.4%)/78 (20.9%); p=0.001; Pain - at 48.5±22.60/51.5±22.80 mm VAS; p=0.043; PGA - 50.2±23.07/54.0±21.91 mm VAS; p=0.010; moderate and severe functional disorders (HAQ-DI) were more often observed in women (p=0.002 and p<0.001, respectively); the average value of DAPSA is 26.4±16.8/31.9±22.58; p<0.001; average BASDAI value: 2.7±2.83/1.8±2.78; p<0.001; MDA was achieved in 13 (3.2%)/22 (4.1%); p=0.486; BSA>10% - 54 (13.1%)/102 (18.7%); p=0.021; comorbid diseases - 154 (37%)/277 (51%); p<0.001. At the time of inclusion in the register, the proportion of patients receiving biologic disease-modifying anti-rheumatic drugs was higher in the group of men. Our data, based on a large cohort study, demonstrate that PsA debuts in women at a later age than in men, the course of the disease is characterized by higher activity of peripheral arthritis, more pronounced functional disorders and a high prevalence of comorbid diseases. This creates a heavier burden of PsA in women and indicates that gender is an important characteristic of the patient that should be used to predict the course, therapeutic response and progression of the disease.

COVID-19: When It Leaves Us Voiceless and Powerless.

Conversion disorder-called functional neurological symptom disorder in the DSM-5-has roots that trace back to antiquity. The term conversion, originating from psychoanalysis, signifies the appearance of physical symptoms as an effort to resolve or convey unconscious and distressing intrapsychic conflicts- "converting" them from manifesting in the mind to manifesting in the body. Despite efforts made in elucidating the neurobiological etiologies of functional neurological symptom disorder, a psychodynamic lens remains indispensable in understanding the patient. This article presents two patients who developed functional neurological symptom disorder, one after a COVID-19 vaccination and one in the context of long COVID. A discussion follows on the intrapersonal, interpersonal, and systemic etiological factors that predispose, precipitate, and perpetuate COVID-related functional neurological symptom disorder. We elaborate on psychodynamic psychological processes and conflicts that may unfold between patients with COVID-related functional neurological symptom disorder and their health care providers. We also share suggestions on how a consultation-liaison psychiatry team may offer support to the primary treating team to facilitate a therapeutic space within which patients with COVID-related functional neurological symptom disorder may recover.

Scintigraphy of Gastrointestinal Motility: Best Practices in Assessment of Gastric and Bowel Transit in Adults.

Various radiologic examinations and other diagnostic tools exist for evaluating gastrointestinal diseases. When symptoms of gastrointestinal disease persist and no underlying anatomic or structural abnormality is identified, the diagnosis of functional gastrointestinal disorder is frequently applied. Given its physiologic and quantitative nature, scintigraphy often plays a central role in the diagnosis and treatment of patients with suspected functional gastrointestinal disorder. Most frequently, after functional gallbladder disease is excluded, gastric emptying scintigraphy (GES) is considered the next step in evaluating patients with suspected gastric motility disorder who present with upper gastrointestinal symptoms such as dyspepsia or bloating. GES is the standard modality for detecting delayed gastric emptying (gastroparesis) and the less commonly encountered clinical entity, gastric dumping syndrome. Additionally, GES can be used to assess abnormalities of intragastric distribution, suggesting specific disorders such as impaired fundal accommodation or antral dysfunction, as well as to evaluate gastric emptying of liquid. More recently, scintigraphic examinations for evaluating small bowel and large bowel transit have been developed and validated for routine diagnostic use. These can be performed individually or as part of a comprehensive whole-gut transit evaluation. Such scintigraphic examinations are of particular importance because clinical assessment of suspected functional gastrointestinal disorder frequently fails to accurately localize the site of disease, and those patients may have motility disorders involving multiple portions of the gastrointestinal tract. The authors comprehensively review the current practice of gastrointestinal transit scintigraphy, with diseases and best imaging practices illustrated by means of case review. ©RSNA, 2024 See the invited commentary by Maurer and Parkman in this issue.

Irritable bowel syndrome following infectious COVID-19: East Java, Indonesia, 2023

Irritable bowel syndrome (IBS) is a functional disorder that causes chronic abdominal pain without a known cause. It is a common, chronic gastrointestinal (GI) motility disorder with bothersome symptoms that often lower quality of life and activity. In addition, Patients and healthcare facilities also face significant financial costs. COVID-19 directly damages the digestive system and alters the complex interaction of physical, mental, and social factors that cause digestive problems. SARS-CoV-2 survivors in personal isolation will be examined for IBS prevalence. The dates of this descriptive cross-sectional study are January through April 2023. Rome IV criteria and an online questionnaire were used to confirm the diagnosis of IBS. The principal location where polls have been sent is East Java, Indonesia. The 96 COVID-19 survivors aged 18–60 of both genders was included during self-quarantine. There were 59 females (61.46%) and 37 males (38.54%). The prevalence of IBS was discovered to be 19 (19.79%) among a total of 96 patients. This could be because self-quarantined people have more stable living conditions than hospitalized people. Based on these findings, it is suggested that future research consider gender as the primary proxy for identifying irritable bowel syndrome (IBS).

High-energy pacing inhibits slow-wave dysrhythmias in the small intestine.

The motility of the gastrointestinal tract is coordinated in part by rhythmic slow waves, and disrupted slow-wave patterns are linked to functional motility disorders. At present, there are no treatment strategies that primarily target slow-wave activity. This study assessed the use of pacing to suppress glucagon-induced slow-wave dysrhythmias in the small intestine. Slow waves in the jejunum were mapped in vivo using a high-resolution surface-contact electrode array in pigs (n = 7). Glucagon was intravenously administered to induce hyperglycemia. Slow-wave propagation patterns were categorized into antegrade, retrograde, collision, pacemaker, and uncoupled activity. Slow-wave characteristics such as period, amplitude, and speed were also quantified. Postglucagon infusion, pacing was applied at 4 mA and 8 mA and the resulting slow waves were quantified spatiotemporally. Antegrade propagation was dominant throughout all stages with a prevalence of 55 ± 38% at baseline. However, glucagon infusion resulted in a substantial and significant increase in uncoupled slow waves from 10 ± 8% to 30 ± 12% (P = 0.004) without significantly altering the prevalence of other slow-wave patterns. Slow-wave frequency, amplitude, and speed remained unchanged. Pacing, particularly at 8 mA, significantly suppressed dysrhythmic slow-wave patterns and achieved more effective spatial entrainment (85%) compared with 4 mA (46%, P = 0.039). This study defined the effect of glucagon on jejunal slow waves and identified uncoupling as a key dysrhythmia signature. Pacing effectively entrained rhythmic activity and suppressed dysrhythmias, highlighting the potential of pacing for gastrointestinal disorders associated with slow-wave abnormalities.NEW & NOTEWORTHY Glucagon was infused in pigs to induce hyperglycemia and the resulting slow-wave response in the intact jejunum was defined in high resolution for the first time. Subsequently, with pacing, the glucagon-induced dysrhythmias were suppressed and spatially entrained for the first time with a success rate of 85%. The ability to suppress slow-wave dysrhythmias through pacing is promising in treating motility disorders that are associated with intestinal dysrhythmias.

Sensory Processing Difficulties and Occupational Therapy Outcomes for Functional Neurological Disorder: A Retrospective Cohort Study.

Occupational therapy (OT) consensus recommendations and articles outlining a sensory-based OT intervention for functional neurological disorder (FND) have been published. However, limited research has been conducted to examine the efficacy of OT interventions for FND. We performed a retrospective cohort study aimed at independently replicating preliminarily characterized sensory processing difficulties in patients with FND and reporting on clinical outcomes of a sensory-based OT treatment in this population. We hypothesized that (1) a history of functional seizures, anxiety, and/or post-traumatic stress disorder would be associated with increased sensory processing difficulties and (2) the number of OT treatment sessions received would positively relate to clinical improvement. Medical records were reviewed for 77 consecutive adults with FND who received outpatient, sensory-based OT care. Data from the Adolescent/Adult Sensory Profile characterized self-reported sensory processing patterns across 4 quadrants (low registration, sensory sensitivity, sensory seeking, and sensory avoidance) in this population. Following univariate screenings, multivariate linear regression analyses were performed to identify neuropsychiatric characteristics associated with discrete sensory processing patterns. Clinical improvement was quantified using an estimated, clinician-determined improvement rating ("improved" vs "not improved"), and relationships between clinical participation, baseline neuropsychiatric factors, and outcomes were investigated. Patients with FND reported sensory processing patterns with elevated scores in low registration, sensory sensitivity, and sensation avoidance compared with normative values; differences in sensory processing scores were not observed across FND subtypes (i.e., motor, seizure, and speech variants). In linear regression analyses, lifetime history of an anxiety disorder, history of migraine headaches, current cognitive complaints, and a comorbid major neurologic condition independently predicted individual differences in sensory processing scores. Following a sensory-based OT intervention, 62% of individuals with FND were clinician determined as "improved." In a multivariate logistic regression analysis controlling for baseline characteristics associated with improvement ratings, number of treatment sessions positively correlated with clinical improvement. These findings support the presence of sensory processing difficulties in patients with FND and provide Class IV evidence for the efficacy of an outpatient, sensory-based OT intervention in this population. Controlled prospective trials are warranted.

Physiotherapy management of functional activity disorders of knee dekstra et cause post-op anterior cruciate ligament reconstruction

Introduction: anterior cruciate ligament injury is one of the common knee injuries among athletes, which can cause functional activity impairment of the knee, such as pain, edema, range of motion limitation, contracture, and anxiety. Anterior cruciate ligament reconstruction is a surgical procedure that aims to restore the stability and function of the knee. Patients who undergo Anterior cruciate ligament reconstruction require appropriate physiotherapy management to accelerate the healing and recovery process. Aim: this study aims to determine the physiotherapy management of functional activity disorders of the knee joints and the causes of postoperative anterior cruciate ligament reconstruction. Methods: this study used a case study method with a research subject of a 24-year-old male who suffered an anterior cruciate ligament injury on the right knee and underwent Anterior cruciate ligament reconstruction. Data were collected using instruments such as the VAS pain scale, goniometer to measure a range of motion, MMT to measure muscle strength, and international knee documentation committee questionnaire to measure functional activity. Results: showed a decrease in pain, an increase in range of motion, an increase in muscle strength, and an increase in functional activity on the right knee caused post-op Anterior cruciate ligament reconstruction after receiving physiotherapy intervention for 9 sessions. Conclusion: physiotherapy management given in the form of electrical muscle stimulation, prone hang, passive range of motion exercise, patella mobilization, isotonic &amp; isometric strengthening, and walking exercise, as well as education, can help overcome functional activity impairment on the right knee et cause post-op anterior cruciate ligament reconstruction.

Mining and analysis of security alert signals of valbenazine based on the Food and Drug Administration Adverse Event Reporting System database.

Valbenazine is used for tardive movement disorders in adults. Current studies on its safety are mostly from clinical trials and small case reports, limiting information on rare adverse reactions. This study investigated valbenazine-related adverse event (AE) risk signals using the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS) database. Valbenazine AEs data were collected from the FAERS database from 2017 Q2 to 2023 Q1, employing methods like reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network, and empirical Bayesian geometric mean. After data cleaning and drug screening, there were 20,837 AEs primarily suspecting valbenazine, involving 26 system organ classes and 125 AEs related to valbenazine at the preferred terms level. AEs related to valbenazine were mainly concentrated in nervous system disorders, general disorders and administration site conditions, and psychiatric disorders. Eye disorders and gastrointestinal disorders are new AEs not labeled in the valbenazine instructions. In addition, some new potential AE signals were found, such as Tardive dyskinesia and eyelid function disorder. The common AEs of valbenazine in the real world are consistent with the instructions, but there are some newly discovered suspicious AEs.

The role of neuropsychology in the care of patients with functional neurological symptom disorder.

Functional neurological symptom disorder (FNSD) is a neuropsychiatric condition characterized by signs/symptoms associated with brain network dysfunction. FNSDs are common and are associated with high healthcare costs. FNSDs are relevant to neuropsychologists, as they frequently present with chronic neuropsychiatric symptoms, subjective cognitive concerns, and/or low neuropsychological test scores, with associated disability and reduced quality of life. However, neuropsychologists in some settings are not involved in care of patients with FNSDs. This review summarizes relevant FNSD literature with a focus on the role of neuropsychologists. A brief review of the literature is provided with respect to epidemiology, public health impact, symptomatology, pathophysiology, and treatment. Two primary areas of focus for this review are the following: (1) increasing neuropsychologists' training in FNSDs, and (2) increasing neuropsychologists' role in assessment and treatment of FNSD patients. Patients with FNSD would benefit from increased involvement of neuropsychologists in their care.

Knowledge and personal hygiene behavior during menstruation among adolescent girls in various regions: A literature review

Personal hygiene is still a public health issue in Indonesia. Menstrual hygiene is the management of hygiene and health when women experience menstruation as part of a personal hygiene care routine with the concept of clean. Personal hygiene during menstruation plays an important role in a person's health status in avoiding functional disorders of the reproductive organs. Knowledge in Indonesia states that poor personal hygiene behavior during menstruation of adolescent girls is a major concern because it has a health impact. The method used was literature review by searching articles through Google Scholar and Pubmed databases. Selection stages were carried out to obtain articles that met the inclusion and exclusion criteria, and 6 articles were obtained that could be analyzed. The results showed that knowledge has a significant role in determining menstrual hygiene behavior in adolescent girls, there are also differences in knowledge and behavior when performing personal hygiene behavior during menstruation in urban and rural areas. To improve knowledge and behavior of personal hygiene during menstruation, especially in various regions, it can be done with various strategies such as promotion, education, collaboration, improving service quality, and increasing accessibility.

Functional disorders in amyotrophic lateral sclerosis

Background. Amyotrophic lateral sclerosis (ALS) is a disease of the parts of the nervous system that control voluntary muscle movement. In ALS, motor neurons (nerve cells that control muscle cells) are gradually lost. As this happens, the muscles they control become weak and then nonfunctional, thus leading to muscle weakness, disability, and eventually death. ALS is the most common form of motor neuron disease. Recent studies widely demonstrated that the pattern of progression in sporadic ALS patients is unsolved mystery, especially what factors influence the progression of the disease. Therefore, we conducted a study using ALS Functional Rating Scale-Revised (ALSFRS-R) for disease progression and investigated factors contributing to its rapid rate in The First University Clinic of Tbilisi State Medical University in 2019–2022. Materials and methods. A total of 60 patients with ALS were examined, among them 31 male (51.67 %), 29 female (48.33 %) aged 21–84 years. Riluzole takers, patients with sporadic ALS underwent brain magnetic resonance imaging, and electrophysiological studies were done in all patients. Participants were diagnosed using the Gold Coast criteria and examined with the ALSFRS-R. Survey for factors affecting disease progression was performed with a help of the patient’s caregiver (a disease-specific questionnaire was invented for this purpose, investigating probable progression modifiers). Results. It has been found that recent falls, trauma, surgery, and infection have a drastic impact on disease progression. ALS was found to be a not linear progressive disease and can vary. We have found that 5 % of patients had improvement оn ALSFRS-R, not explained by medication, nor lifestyle change. Conclusions. The rate of ALS progression appears to be a mystery by itself. Predicting the progression rate, and the factors affecting it would be beneficial for ALS patients and may even bring chances to slow or halt the progression. Further research is essential.
