Clinical characteristics of cerebral amyloid angiopathy and risk factors of cerebral amyloid angiopathy related intracerebral hemorrhage.

There is limited understanding of the differences between cerebral amyloid angiopathy (CAA) with and without intracerebral hemorrhage (ICH). This article aimed to describe the characteristics of CAA and identify the risk factors of CAA-ICH in a multicenter cohort. Patients consecutively enrolled in the national multicenter prospective Cerebral Small Vessel Disease Cohort Study who met the Boston diagnostic criteria for CAA or CAA-related inflammation were included in this study. The demographic characteristics and clinical data were collected. The clinical and radiographic differences between CAA with and without ICH were compared to identify the risk factors for CAA-ICH. A total of 219 CAA patients were included, with an average age of 67.12 ± 9.93. Of all patients, 26.0% were CAA with ICH. Univariate analysis showed that CAA-ICH is associated with carrying more APOE ε2 allele, less lobar cerebral microbleeds (CMBs), cortical superficial siderosis (cSS), lower Fazekas scale, a tendency of gait disorder, and acute onset (P < 0.05). The generalized linear mixed model yielded statistically significant associations between CAA with ICH and carrying the APOE ε2 allele, cSS, the lower number of lobar CMBs, and the lower Fazekas scale (P < 0.05). It is meaningful to classify CAA with and without ICH, as there may be different mechanisms between the two. CAA with ICH has a susceptibility to carrying APOE ε2, cSS, and a relatively small number of CMBs. Fewer CMBs do not mean lower susceptibility to ICH in CAA. Larger prospective cohort studies are necessary to further clarify these conclusions.

Unplanned transfer to acute care during inpatient geriatric rehabilitation: incidence, risk factors, and associated short-term outcomes

BackgroundInformation is scarce on unplanned transfers from geriatric rehabilitation back to acute care despite their potential impact on patients’ functional recovery. This study aimed 1) to determine the incidence rate and causes of unplanned transfers; 2) to compare the characteristics and outcomes of patients with and without unplanned transfer.MethodsConsecutive stays (n = 2375) in a tertiary geriatric rehabilitation unit were included. Unplanned transfers to acute care and their causes were analyzed from discharge summaries. Data on patients’ socio-demographics, health, functional, and mental status; length of stay; discharge destination; and death, were extracted from the hospital database. Bi- and multi-variable analyses investigated the association between patients’ characteristics and unplanned transfers.ResultsOne in six (16.7%) rehabilitation stays was interrupted by a transfer, most often secondary to infections (19.3%), cardiac (16.8%), abdominal (12.7%), trauma (12.2%), and neurological problems (9.4%). Older patients (AdjORage≥85: 0.70; 95%CI: 0. 53–0.94, P = .016), and those admitted for gait disorders (AdjOR: 0.73; 95%CI: 0.53–0.99, P = .046) had lower odds of transfer to acute care. In contrast, men (AdjOR: 1.71; 95%CI: 1.29–2.26, P < .001), patients with more severe disease (AdjORCIRS: 1.05; 95%CI: 1.02–1.07, P < .001), functional impairment before (AdjOR: 1.69; 95%CI: 1.05–2.70, P = .029) and at rehabilitation admission (AdjOR: 2.07; 95%CI: 1.56- 2.76, P < .001) had higher odds of transfer. Transferred patients were significantly more likely to die than those without transfer (AdjOR 13.78; 95%CI: 6.46–29.42, P < .001) during their stay, but those surviving had similar functional performance and rate of home discharge at the end of the stay.ConclusionA significant minority of patients experienced an unplanned transfer that potentially interfered with their rehabilitation and was associated with poorer outcomes. Men, patients with more severe disease and functional impairment appear at increased risk. Further studies should investigate whether interventions targeting these patients may prevent unplanned transfers and modify associated adverse outcomes.

Gait disorders are the most frequent symptoms associated to multiple sclerosis (MS). Robot-assisted gait training (RAGT) in people with MS (PwMS) has been proposed as a possible effective treatment option...

Geriatric ophthalmologic co-management : A case report of interdisciplinary collaboration

This case report details the assessment and interdisciplinary collaboration in the management of an 81-year-old patient presenting with acute visual impairment, dizziness, general weakness, gait disturbances and fear of falling. A holistic geriatric evaluation revealed orthostatic dysregulation and an underlying multifactorial gait disorder exacerbated by visual impairment. Ophthalmological findings included left central retinal artery branch occlusion and cataracts. A comprehensive geriatric assessment showed frailty, impaired mobility and decreased functional abilities. Subsequent patient-centered interdisciplinary approaches included treatment for retinal ischemia, orthostatic testing, medication reconciliation, physiotherapy and occupational therapy. This case emphasizes how interdisciplinary collaboration between ophthalmology and geriatrics enables proactive assessment and intervention to reduce the risk of functional decline and loss of autonomy in visually impaired patients, which is of particular relevance considering the increasing prevalence of visual impairment in the ageing population.

Amelioration of gait and balance disorders by rosuvastatin is associated with changes in cerebrovascular reactivity in older patients with hypertensive treatment.

To investigate the effect of rosuvastatin on gait and balance disorder progression and elucidate the role of cerebrovascular reactivity (CVR) on this effect. From April 2008 to November 2010, 943 hypertensive patients aged ≥60 years were enrolled from the Shandong area of China. Patients were randomized into rosuvastatin and placebo groups. Gait, balance, CVR, fall and stroke were assessed. During an average 72 months of follow-up, the decreasing trends for step length, step speed, and Berg balance scale scores and the increasing trends for step width and chair rising test were slower in the rosuvastatin group when compared to the placebo group. The hazard ratio of incident balance impairment and falls was 0.542 [95% confidence interval (CI) 0.442-0.663] and 0.532 (95% CI 0.408-0.694), respectively, in the rosuvastatin group compared with placebo group. For CVR progression, the cerebrovascular reserve capacity and breath-holding index were increased and the pulsatility index decreased in the rosuvastatin group, while the cerebrovascular reserve capacity and breath-holding index were decreased, and pulsatility index increased in the placebo group. The changes in gait stability and balance function were independently associated with the changes in the CVR. The odds risks of balance impairment and falls were 2.178 (95% CI: 1.491-3.181) and 3.227 (95% CI: 1.634-6.373), respectively, in the patients with CVR impairment and patients without CVR impairment. Rosuvastatin ameliorated gait and balance disorder progression in older patients with hypertension. This effect might result from the improvement in the CVR. This double-blind clinical trial recruited 943 hypertensive patients aged ≥60 years who were randomly administered rosuvastatin and placebo interventions. The data indicates that rosuvastatin significantly ameliorated the progressions of gait and balance disorders in older hypertensive patients. The cerebrovascular reactivity might play an important mediating role in this amelioration.

Relationship between sensation and balance and gait in multiple sclerosis patients with mild disability

BackgroundPatients with Multiple Sclerosis (PwMS) often experience sensory, balance, and gait problems. Impairment in any sensation may increase imbalance and gait disorder in PwMS. This study aimed to (1) compare foot plantar sensations, knee position sense, balance, and gait in PwMS compared to Healthy Individuals (HI) and (2) examine the relationship between plantar sensations, knee position sense, balance, and gait in PwMS. MethodsThirty PwMS with mild disability and 10 HI participated in this study. Light touch threshold, two-point discrimination, vibration duration, and knee position sense were examined on the Dominant Side (DS) and Non-Dominant Side (NDS). Balance and spatio-temporal gait analysis were evaluated in all participants. ResultsPwMS had higher postural sway with eyes closed on the foam surface, longer swing phase of DS, longer single support phase of NDS, and shorter double support phase of DS compared to HI (p < 0.05). The results of regression analysis showed that the light touch thresholds of the 1st and 5th toes of the DS were associated with postural sway in different sensory conditions (p < 0.05). In contrast, the light touch thresholds of the 1st and 5th toes, two-point discrimination of the heel, vibration duration of the 1st metatarsal head and knee position sense of the NDS, and light touch threshold in the medial arch of both sides were associated with the gait parameters (p < 0.05). ConclusionPwMS, even with mild disabilities needs neurorehabilitation to improve plantar sensation and knee position sense.

Stride width and postural stability in frontal gait disorders and Parkinson's disease.

Older adults, as well as those with certain neurological disorders, may compensate for poor neural control of postural stability by widening their base of foot support while walking. However, the extent to which this wide-based gait improves postural stability or affects postural control strategies has not been explored. People with idiopathic Parkinson's disease (iPD, n = 72), frontal gait disorders (FGD, n = 16), and healthy older adults (n = 32) performed walking trials at their preferred speed over an 8-m-long, instrumented walkway. People with iPD were tested in their OFF medication state. Analyses of covariance were performed to determine the associations between stride width and measures of lateral stability control. People with FGD exhibited a wide-based gait compared to both healthy older adults and iPD. An increased stride width was associated with an increase in lateral margin of stability in FGD. Unlike healthy older adults or iPD, people with FGD did not externally rotate their feet (toe-out angle) or shift their center of pressure laterally to aid lateral dynamic stability during walking but slowed their gait instead to increase stability. By adopting a slow, wide-based gait, people with FGD take advantage of the passive, pendular mechanics of walking.

Normal pressure hydrocephalus and cognitive impairment: The gait phenotype matters too.

Idiopathic normal pressure hydrocephalus (iNPH) is a chronic neurological disease resulting in progressive gait and cognitive disorders. We investigated whether the gait phenotype is associated with the severity of cognitive deficits in iNPH. This retrospective study recruited 88 patients (mean age = 76.18 ± 7.21 years, 42% female). Patients were initially referred for suspicion of iNPH and underwent a comprehensive analysis, including gait analysis and cognitive evaluation. In this cohort (27% normal gait, 25% frontal gait, 16% parkinsonian gait, 27% other gait abnormalities), patients with parkinsonian and frontal gait had the lowest Mini-Mental State Examination (MMSE) scores and the slowest gait speed. Patients with normal gait had the highest MMSE scores and gait speed. Frontal gait was associated with lower MMSE score, even after adjusting for age, gender, comorbidities, white matter lesions, and education level (β = -0.221 [95% confidence interval (CI) = -3.718 to -0.150], p = 0.034). Normal gait was associated with the best MMSE scores, even after adjusting for the abovementioned variables (β = 0.231 [95% CI = 0.124-3.639], p = 0.036). Gait phenotypes among iNPH patients are linked to global cognition as assessed with MMSE.

Neuropsychiatric Manifestations and Neuroimaging Changes of Neurologic Wilson Disease–A Cross Sectional Study

Background: Wilson disease is genetic disorder of copper metabolism which causes hepatic &amp; neurologic manifestation mainly. Chelator therapy is usually given as first line treatment in symptomatic wilson disease. Objective: Objective of our study was to evaluate the neuropsychiatric menufestations of wilson disease. Methods: A Cross sectional study was conducted at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, a tertiary care premier Postgraduate Medical Institution of Bangladesh. Forty five (45) patients of neurologic wilson disease were evaluated at In-patient department of Paediatric Neurology, during the period of January 2015 to December 2020. Diagnosis of Neurologic wilson disease was done, based on the characteristic clinical features of progressive deterioration of scholastic performances, dysarthria and gait disorder along with ophthalmologic findings, biochemical &amp; neuroimaging findings.

CHRONOTYPE AND DAILY FUNCTIONING OF PATIENTS WITH DIFFERENT MOTOR SUBTYPES OF PARKINSON DISEASE

Introduction. Sleep and circadian rhythm disturbances can occur at any stage of Parkinson disease (PD) and significantly affect quality of life. Chronotypes of patients with PD are associated with different phenotypes, in particular with the motor subtype. Thus, we hypothesized that patients with different motor subtypes of PD may have differences in the distribution of chronotypes and patterns of daily activity. Methods and materials. We conducted clinical research on the basis of the Centre for Parkinson Disease and Neurodegenerative Diseases of the Department of Neurological Diseases of Poltava State Medical University. PD was verified according to the recommendations of the International Movement Disorders and Parkinson's Disease Society. The motor subtype of PD was determined by the Stebbin method, which is based on the calculation of the Stebbins coefficient by the sum of the Unified PD Rating Scale scores. The examined patients were divided into 3 groups according to the motor subtype of PD: group 1 (n = 38) - patients with PD subtype with the predominance of postural instability and gait disorders (PIGD); group 2 (n = 26) - patients with PD subtype with the predominance of tremor and mixed subtype; control group (n = 30) - conditionally healthy individuals without CNS lesions. Circadian patterns were analyzed using the Munich Chronotype Questionnaire (MCTQ). Results. It was found that in PD patients sleep onset and time of getting out of bed was later (p&lt;0.001 and p=0.042, respectively), sleep latency was longer (p&lt;0.001), sleep duration was shorter (p=0.001), the mid-sleep corresponded to a later time (p&lt;0.001). Patients with the PIGD subtype had a later time of getting out of bed (p=0.038), longer sleep inertia (p&lt;0.001), shorter sleep duration (p&lt;0.001), and later mid-sleep time (p=0.028). We have shown the tendency of patients with PD, mostly in the PIGD subtype, to later chronotypes (p&lt;0.001). Light exposure indirectly moderately correlated with mid-sleep in all study groups. It was found that both the motor subtype (p&lt;0.001) and the level of light exposure during the day (p&lt;0.001) statistically significantly affect the mid-sleep. Conclusion. Thus, we have found that patients with PD differ from age-matched controls without neurodegenerative diseases by chronotype and circadian pattern of functioning. The motor subtype of the disease is associated with circadian differences, namely, the PIGD subtype is associated with shorter sleep duration, a predisposition to a later chronotype, and longer sleep inertia.

Gait Adaptability and the Effect of Ocular Disorders on Visually Guided Walking in Parkinson's Disease.

Gait disorders are a disabling feature of Parkinson's disease (PD). To avoid falls, people with PD should be able to adequately adapt their gait. This requires correct response inhibition and integration of visual information. In this small pilot study, we investigated PD-related impairments in gait adaptability and the influence of ocular disorders thereon. Compared with controls, persons with PD were less able to adapt their gait in unexpected situations (U = 21.5, p = 0.013), with only a small influence of ocular disorders on precision stepping (U = 6, p = 0.012 in the ML-direction and in the AP-direction, (U = 20, p = 0.456). This shows that people with PD have more difficulty with precision stepping than healthy controls and experience more problems with adapting their gait. We found only a small impact of ocular disorders on successfully execute precision stepping. The ability to adapt gait, particularly in challenging environmental conditions or with impaired vision, may provide a useful assessment and training option for fall prevention in PD.

Assessing cows' mobility to determine their comfort state

Milk production and breeding of highly productive cows using modern innovative technologies have led to specific unfavorable combinations of technological factors in how cows are kept, which has significantly increased their susceptibility to developing various pathological processes in the musculoskeletal system. Lameness is the most common pathology. It is important to note that this information is based on objective evaluations and scientific research. The article is devoted to developing methodological approaches to determine the comfort state of cows based on mobility assessment. When determining the comfort state of a cow, in particular, the detection of diseases of the musculoskeletal system, a three-dimensional image of the animal was used, the position of the specified points of the animal's body was determined (tracking), the kinematic indicators of the movement of these points were calculated, the degree of bending of the animal's back during movement was assessed, complex mobility indicators were calculated, and the calculated complex mobility indicator was compared with the reference one. Based on the research results, a structural and technological scheme of a system for determining the comfort state of an animal based on the assessment of its mobility was developed, and software for video recording of movement was created. The step length, maximum step height, step duration, posture, and free state, as well as the speed of movement of healthy animals, those with single lesions and hoof ulcers were determined, and, as a result, the dynamics of changes in the accelerations of nodal points in the joints for each body link of healthy cows was revealed. The key variables of the biomechanical model for assessing the limbs of cattle (cows) are substantiated. The value of the specific force of the support reaction acting on the hooves of cows was determined: the highest value (9.8 N/kg) was observed for the concrete surface, the lowest (5 N/kg) – for rubber mats. The practical examples of the complex relationship between welfare indicators (lameness), elements of physiology (mobility), and technology (floor type) presented in the publication are recommended to be effectively used in monitoring the results of detecting gait disorders in animals and evaluating its effectiveness even in the early stages of the disease. The prospect of further research is to determine the comfort state of animals depending on environmental and climatic conditions.

Combined diagnosis for Parkinson's disease via gait and eye movement disorders

Background and objectivesWith the discovery of the potential role of gait and eye movement disorders in Parkinson's disease (PD) recognition, we intend to investigate the combined diagnostic value of gait and eye movement disorders for PD. MethodsWe enrolled some Chinese PD patients and healthy controls and separated them into the training and validation sets based on enrollment time. Performance in five oculomotor paradigms and in one gait paradigm was examined using an infrared eye tracking device and a wearable gait analysis device. We developed and validated a combined model for PD diagnosis via multivariate stepwise logistic regression analysis. Furthermore, subgroup comparisons and multi-model comparison were performed to assess its applicability and advantages. ResultsA total of 145 PD patients and 80 healthy controls in China were recruited. The pro-saccade velocity, the trunk-sway max, and the turn mean angular velocity were finally screened out for the model development. Incorporating age factor, the ternary model demonstrated more satisfactory performance on ROC (AUC of 0.953 in the training set and AUC of 0.972 in the validation set), calibration curve, and decision curve. A nomogram was drawn to visualize the model. The combined model outperforms individual models with a broad application and the unique diagnostic value for early detection of PD patients, especially TD-PD patients. ConclusionWe demonstrated the presence of gait and eye movement disorders, as well as the feasibility, applicability, and superiority of employing them together to diagnose PD.

Sufficiency for PSS tracking gait disorders in multiple sclerosis: A managerial perspective

This study primarily aimed to explore the capabilities of digitalisation in the healthcare context, focusing on a specific disease. In this case, the study examined the potential of remote monitoring of gait to address the sensitivity of multiple sclerosis progression to gait characteristics by adopting a non-invasive approach to remotely quantify gait disturbances in a patient's daily life. To better understand the managerial aspects associated with this approach, the researchers conducted a literature review along with a set of semi-structured interviews. The target population included MS patients as well as the key agents involved in their care: patients' family members, neurologists, MS nurses, physiotherapists, medical directors, and pharmacist. The study identifies the perceived barriers and drivers that could contribute to the successful deployment of PSS remote gait monitoring as a healthcare service: i) At mega-level governance. Implications on privacy and security data are notable barriers missing on the speech. ii) At macro level, funding is highlighted as main barrier. The cost and lack of health system subsidies may render initiatives unsustainable, as emphasised by the interviewees. iii) At meso level, useable data is recognised as a driver. The data collection process can align with diverse interests to create value and business opportunities for the ecosystem actors, enhance care, attract stakeholders, such as insurers and pharma, and form partnerships. iv) At micro-level processes, we find two potential barriers: wearable device and app usability (comfort, navigation, efficiency) and organisational/behavioural aspects (training, digital affinity, skills), which are crucial for value creation in innovation ecosystems among patients and healthcare professionals. Finally, we find an interesting gap in the literature and interviews. Stakeholders' limited awareness of technological demands, especially from information technologies, for a successful long-term service, can be consider two key barriers for PSS.

Enhancing gait cadence through rhythm-modulated music: A study on healthy adults

Gait disorders stemming from brain lesions or chemical imbalances, pose significant challenges for patients. Proposed treatments encompass medication, deep brain stimulation, physiotherapy, and visual stimulation. Music, with its harmonious structures, serves as a continuous reference, synchronizing muscle activities through neural connections between hearing and motor functions, can show promise in gait disorder management. This study explores the influence of heightened music rhythm on young healthy participants' gait cadence in three conditions: FeedForward (independent rhythm), FeedBack (cadence-synced rhythm), and Adaptive (cadence-controlled musical experience). The objective is to increase gait cadence through rhythm modulation during walking. The study involved 18 young healthy participants (13 males and 5 females) who did not have any gait or hearing disorders. Each participant completed the gait task in the three aforementioned conditions. Each condition was comprised of three sessions: 1) Baseline, where participants walked while listening to the original music; 2) Intervention, changing the music rhythm to affect the gait cadence; and 3) Realign, replaying the original music and measuring the durability of the effect of the Intervention session. The measurement tool was a pair of footwear equipped with push-button switches that transmited the foot-to-ground contact to the LabVIEW® software, all designed by the research team. Repeated measures of ANOVA was employed to evaluate the impact of the sessions and conditions. In all three conditions, there was a significant effect of music on increasing gait cadence during Intervention and Realign sessions (p<0.001). Additionally, the immediate impact of music on gait cadence in the Adaptive condition was superior to the other conditions. The study findings indicate that increasing the rhythm of music during walking has a significant impact on gait cadence among young healthy participants. This effect remained significant even after realigning the music to normal. It could be harnessed to support the rehabilitation of individuals with movement disorders characterized by a decrease in movement speed, such as Parkinson's disease. Moreover, the results indicate that the Adaptive method showed promising outcomes, suggesting its potential for further exploration as an effective means to control gait cadence.

Effect of Selected Kinesiology Taping Applications on Reducing Pain and Accelerating Rehabilitation in Children with Osgood-Schlatter Disease

Introduction: Osgood-Schlatter disease (OSD) is a very common disease in children and youth during the adolescent period. This condition is characterised by pain and significant swelling along with deformity of the tibial tuberosity region, which often results in the disorder of correct gait and decreased level of physical activity.

Prescribing medications for Parkinson's: part two

Around 10 million people worldwide have Parkinson's and in the UK the estimated figure is 153 000. The condition is characterised by motor symptoms including tremors, stiffness, slowness, balance problems and/or gait disorders, but people can develop a wide range of associated psychological and physical problems. Treatment for Parkinson's includes a combination of multidisciplinary input from specialists such as physiotherapy, speech and language therapy and occupational therapy, alongside the use of recognised medication regimens. Most first-line medication requires titration and is started at a low dose and increased gradually, to reduce the risk of side effects and to monitor response to treatment. Medications for Parkinson's are complex to manage, and many have side effects that could affect patient concordance. Any prescribing decisions should be discussed with the person with Parkinson's and their family members. There are a variety of medications available to manage motor and non-motor symptoms in Parkinson's, but this article will focus on levodopa, dopamine agonists, MAO-B inhibitors and catechol-O-methyltransferase inhibitors.

Accelerometer-based gait characteristics and their discrimination of gait independence in inpatients with subacute stroke

BackgroundGait analysis using inertial measurement devices can identify multifaceted gait disorders after a stroke. Although the usefulness of gait assessment using inertial measurement devices has been reported, its accuracy in discriminating gait independence in patients hospitalized for subacute stroke has not yet been validated. Research questionCan trunk acceleration indices discriminate between dependent and independent walking in patients with subacute stroke? MethodsThirty-five patients with subacute stroke (mean ± standard deviation, 75.5 ± 9.8 years, 19 males), who were able to understand instructions, had a premorbid modified Rankin scale <3, and were able to walk 16 m straight ahead under supervision were included. The stride regularity, harmonic ratio, and normalized root mean square of trunk accelerations were measured in three directions (mediolateral, vertical, and anterioposterior) during comfortable walking. The Functional Ambulation Categories were used as the dependent variable to classify the patients into two groups (dependent and independent walking groups), and each trunk acceleration index was used as the independent variable to calculate the area under the curve using receiver operating characteristic curves. ResultsTwelve patients were in the dependent group and 23 were in the independent group. The normalized root mean square in both the mediolateral and vertical directions were excellent discriminators of walking independence, with an area under the curve greater than 0.8. The cutoff values (sensitivity/specificity) were 2.20 m2/s2 (0.783/0.833) and 2.82 m2/s2 (0.739/0.833), respectively. SignificanceThe magnitude of vertical and lateral acceleration during gait in patients with subacute stroke, has excellent accuracy in discriminating between dependent and independent gaits. The results of this study will be useful for inexperienced clinicians working with stroke patients presenting with gait disturbances to accurately determine gait independence based on objective data.

Underrated and Underestimated – Deprivation in Dementia. A Case Report

Introduction Deprivation is widely known in children and adolescents and means a lack of social, emotional, or sensory stimuli, due to disabilities such as deafness, but also social isolation and reduced parental care. It may cause developmental disorders such as impaired language, motoric and social development. Little is known of the impact of social deprivation in demented patients.Stimulus shielding, which is a widespread option for psychiatric symptoms of dementia such as agitation, vocalization and aggressive behavior may – if frequently used- have similar effects on demented patients.ObjectivesWe report the case of a 71-year-old patient with dementia caused by PSP (Progressive Supranuclear Palsy), who was in inpatient treatment due to continuous undirected vocalizations. She presented with inability to walk, dysarthria, aphasia, and hearing difficulties beside major mnestic impairment. In a prior hospitalization and in her residency, she was frequently isolated from other patients due to loud screaming and vocalizations in terms of stimulus shielding by suspected overstimulation. In order to that, for four months, she developed progressive difficulties to speak, hear, understand, as well as gait disorders. In addition, the vocalizations increased.Methods We rated the symptoms due to deprivation, triggered by lack of mobilization, social experiences, visual, tactile and acoustic stimuli following a vicious circle of anxiety, vocalizations and recurrent isolations. Therefore, a multimodal therapy assessment was implemented, including daily physical therapy, mobilization, basal stimulation, social reintegration and basal conversation training.Results After a few days of high intensity treatment, speech reappeared in form of one- word sentences and proceeded to the ability to have short conversations. Mobility increased, starting from severe gait disorder, including the use of a wheelchair and emerged to the ability of walking up to 50 metres. Additionally, the undirected vocalizations improved and were reduced. In addition, hearing ability improved during the four-week treatment.Conclusions This case highlights the impact of deprivation in demented patients. Especially it shows that these symptoms can be reversible under a high intensity multimodal and multi- professional treatment within a few weeks. Therefore, stimulus shielding, should be carefully evaluated in order to prevent deprivation – and thus deterioration of the symptoms – in demented patients.Disclosure of InterestNone Declared
