Neurorehabilitation in brain tumours: evidences and suggestions for spreading of knowledge and research implementation.

PURPOSE OF REVIEW: The last few decades have seen an increase in life expectancy in brain tumour patients; however, many patients report sensory-motor and cognitive disabilities due to the tumour itself, but also to the effect of anticancer treatments (surgery, radiotherapy, chemotherapy), supportive treatments, as well as individual patient factors. This review outlines the principles on which to base neurorehabilitation treatments, with the aim of stimulating an early rehabilitative management, in order to reduce disability and functional limitation and improve the quality of life of the persons affected by brain tumour. RECENT FINDINGS: Although not definitive, evidences suggest that an early neurorehabilitative evaluation, performed with a multidisciplinary approach, may identify the different functional impairments that can affect people with brain tumour. Furthermore, identifying and classifying the person's level of functioning is useful for designing achievable recovery goals, through the implementation of tailored multidisciplinary rehabilitation programs. The involvement of different professional figures allows to treat all the components (physical, cognitive, psychological and participation) of the person, and to redesign one's life project, lastly improving the quality of life. SUMMARY: Overall, the evidences suggest a critical need for the development of this clinical area by spreading the concept of rehabilitation among neuro-oncologists and producing high quality research.

Technology Assisted Rehabilitation Patient Perception Questionnaire (TARPP-Q): development and implementation of an instrument to evaluate patients' perception during training.

BACKGROUND: The introduction of technology-assisted rehabilitation (TAR) uncovers promising challenges for the treatment of motor disorders, particularly if combined with exergaming. Patients with neurological diseases have proved to benefit from TAR, improving their performance in several activities. However, the subjective perception of the device has never been fully addressed, being a conditioning factor for its use. The aims of the study were: (a) to develop a questionnaire on patients' personal experience with TAR and exergames in a real-world clinical setting; (b) to administer the questionnaire to a pilot group of neurologic patients to assess its feasibility and statistical properties. METHODS: A self-administrable and close-ended questionnaire, Technology Assisted Rehabilitation Patient Perception Questionnaire (TARPP-Q), designed by a multidisciplinary team, was developed in Italian through a Delphi procedure. An English translation has been developed with consensus, for understandability purposes. The ultimate version of the questionnaire was constituted of 10 questions (5 with multiple answers), totalling 29 items, exploring the patient's performance and personal experience with TAR with Augmented Performance Feedback. TARPP-Q was then administered pre-post training in an observational, feasible, multi-centric study. The study involved in-patients aged between 18 and 85 with neurological diseases, admitted for rehabilitation with TAR (upper limb or gait). FIM scale was run to control functional performance. RESULTS: Forty-four patients were included in the study. All patients answered the TARPP-Q autonomously. There were no unaccounted answers. Exploratory factor analyses identified 4 factors: Positive attitude, Usability, Hindrance perception, and Distress. Internal consistency was measured at T0. The values of Cronbach's alpha ranged from 0.72 (Distress) to 0.92 (Positive attitude). Functional Independence Measure (FIM®) scores and all TARPP-Q factors (Positive attitude, Usability, Hindrance perception, except for Distress (p = 0.11), significantly improved at the end of the treatment. A significant positive correlation between Positive attitude and Usability was also recorded. CONCLUSIONS: The TARPP-Q highlights the importance of patients' personal experience with TAR and exergaming. Large-scale applications of this questionnaire may clarify the role of patients' perception of training effectiveness, helping to customize devices and interventions.

Risk factors for 2-year mortality in patients with prolonged disorders of consciousness: An international multicentre study.

BACKGROUND AND PURPOSE: Patients with prolonged disorders of consciousness (pDoC) have a high mortality rate due to medical complications. Because an accurate prognosis is essential for decision-making on patients' management, we analysed data from an international multicentre prospective cohort study to evaluate 2-year mortality rate and bedside predictors of mortality. METHODS: We enrolled adult patients in prolonged vegetative state/unresponsive wakefulness syndrome (VS/UWS) or minimally conscious state (MCS) after traumatic and nontraumatic brain injury within 3 months postinjury. At enrolment, we collected demographic (age, sex), anamnestic (aetiology, time postinjury), clinical (Coma Recovery Scale-Revised [CRS-R], Disability Rating Scale, Nociception Coma Scale-Revised), and neurophysiologic (electroencephalogram [EEG], somatosensory evoked and event-related potentials) data. Patients were followed up to gather data on mortality up to 24 months postinjury. RESULTS: Among 143 traumatic (n = 55) and nontraumatic (n = 88) patients (VS/UWS, n = 68, 19 females; MCS, n = 75, 22 females), 41 (28.7%) died within 24 months postinjury. Mortality rate was higher in VS/UWS (42.6%) than in MCS (16%; p < 0.001). Multivariate regression in VS/UWS showed that significant predictors of mortality were older age and lower CRS-R total score, whereas in MCS female sex and absence of alpha rhythm on EEG at study entry were significant predictors. CONCLUSIONS: This study demonstrated that a feasible multimodal assessment in the postacute phase can help clinicians to identify patients with pDoC at higher risk of mortality within 24 months after brain injury. This evidence can help clinicians and patients' families to navigate the complex clinical decision-making process and promote an international standardization of prognostic procedures for patients with pDoC.

Recovery and long term functional outcome in people with critical illness polyneuropathy and myopathy: a scoping review.

BACKGROUND: Intensive care unit acquired weakness (ICUAW), embraces an array of disorders labeled "critical illness polyneuropathy" (CIP), "critical illness myopathy" (CIM) or "critical illness polyneuromyopathy" (CIPNM). Several studies have addressed the various characteristics of ICUAW, but the recovery is still unclear. OBJECTIVE: The present review investigated the recovery and the long-term functional outcome of subjects with ICUAW, whether the types of ICUAW have different outcomes and whether there is any supporting evidence. METHODS: Literature search was performed from MEDLINE/PubMed, CINAHL, EMBASE, PeDro, Web of Science and Scopus. Inclusion criteria were: i) sample size including five or more subjects; ii) subjects who suffered from ICUAW and/or CIP, CIM and CIP/CIM; iii) ICUAW ascertained by EMG. Follow-ups longer than one year were defined as long-term. RESULTS: Twenty-nine studies met the inclusion criteria. In total, 788 subjects with ICUAW were enrolled: 159 (20.1%) died and 588 (74.6%) were followed. Of all the included patients, 613 (77.7%) had CIP, 82 (10.4%) CIM and 56 (7.1%) CIP/CIM. Overall, 70.3% of the subjects with ICUAW fully recovered. Seven (24.1%) studies had a follow-up longer than 1 year (range 2-8) with 173 (21.9%) subjects enrolled globally and 108 followed. Of these subjects, 88.8% gained full recovery. Most of the studies did not use proper functional scales and only 4 and 3 studies employed the Barthel scale and the Functional Independence Measure (FIM) scale. Differentiation between the types of ICUAW was performed in 7 studies, but only 3 studies reported that subjects with CIM had a better prognosis and earlier recovery than subjects with CIP/CIM. CONCLUSIONS: Subjects with ICUAW could achieve good recovery and could improve at follow-up. However, the quality of the published studies due to short follow-ups and the paucity of defined outcome measures require confirms.

From DYMUS to DYPARK: Validation of a Screening Questionnaire for Dysphagia in Parkinson's Disease.

Dysphagia is a common debilitating symptom in people with Parkinson's Disease (PD), adequate screening of swallowing disorders is fundamental. The DYMUS questionnaire has shown very good characteristics for the screening of dysphagia in Multiple Sclerosis, and it might also prove useful for screening dysphagia in PD. The primary aim was to test and validate the DYMUS questionnaire in PD patients. This is an observational multicentric study involving 103 patients affected by PD. All subjects filled in the DYMUS and the Eating Assessment Tool (EAT-10) questionnaires. A subgroup of patients (n = 53) underwent a fiber-optic endoscopic evaluation of swallowing (FEES) and their dysphagia was scored by means of the Dysphagia Outcome Severity Scale (DOSS). DYMUS showed a relatively high level of internal consistency (Cronbach's alpha 0.79). A significant positive correlation was found between the DYMUS and the EAT-10 scores (p < 0.001), while a negative correlation was found between the DYMUS and the DOSS scores (p < 0.001). DYMUS showed a good sensitivity and specificity compared to FEES for detecting dysphagia (area under the curve: 0.82, p < 0.001). The ROC curve analysis showed that a DYMUS score ≥ 6 represents a reliable cut-off for the risk of dysphagia. The DYMUS questionnaire proved to be a reliable screening tool to detect dysphagia in patients suffering from PD. It is easy to understand, it can be self-administered and therefore adequate for adoption in the clinical practice with the more convenient name of DYPARK.

User-centered practices in the eyes of informal caregivers of in-patients with severe acquired brain injury: needs, caring experience, and satisfaction.

OBJECTIVE: This study examines the perceived needs, experience, and satisfaction of informal caregivers (ICGs) in in-hospital settings, related to their involvement in the design and delivery of services together with hospital staff, namely co-production. DESIGN: To obtain a picture of current ICG-staff relationship, a multicenter observational study was carried out. Participants were 75 ICGs recruited in five dedicated in-patient neurorehabilitation wards. Participants answered a self-report questionnaire tapping perceived information/communication needs, emotional/social needs, and their satisfaction; family-centered practices implemented by the staff (namely involving practices and cooperative communication); and ICGs' satisfaction with the service. RESULTS: Need satisfaction related positively to staff practices aimed at involving IGCs in treatment and training, but not in decision-making. Involving practices concerning treatment also related positively to ICGs' information/communication needs. In addition, the more the staff involved ICGs in decision-making and promoted cooperative communication regarding treatment, the more ICGs felt that their collaboration in the healthcare process was valuable. Finally, all involvement practices and cooperative communication were positively related to ICGs' overall satisfaction with the service. CONCLUSION: The results of the study help to identify gaps in meeting ICGs' needs and to promote strategies to implement family participation toward co-production in in-hospital settings.

Vitamin D serum level in subjects with critical illness polyneuropathy and myopathy.

BACKGROUND: Critical illness polyneuropathy and myopathy (CIPNM) is a disabling neuropathy that occurs in intensive care unit (ICU) subjects. It was hypothesized that a low serum level or deficiency of 25(OH)D might be associated with CIPNM. The aim of the present study was to ascertain the 25(OH)D serum level in subjects with CIPNM. METHOD: Consecutive ICU patients admitted to neuro-rehabilitation were prospectively enrolled. At admission, vitamin D serum levels were measured and EMG examination was performed to ascertain those with CIPNM. 25(OH)D was stratified as sufficient (≥30 ng/mL) insufficient (20-29.9 ng/mL), and deficient (<20 ng/mL). RESULTS: Eighty-four patients (31 F, 53 M; mean age 51.7±12.6) were identified and 63 (21 F, 42 M) enrolled. CIPNM was detected in 38 (9 F, 29 M) patients. A deficient mean serum level of vitamin D was observed in the whole population: 18.1 ± 9.2 ng/mL. No difference of vitamin D serum levels was detected in subjects with and without CIPNM: 17.5 ± 8.4 and 19.0 ± 10.5 ng/mL (p=0.58), respectively. CONCLUSION: Almost all subjects showed Vitamin D deficiency. No difference was detected between those with and without CIPNM. The condition might represent a secondary phenomenon resulting from the inflammatory process as well as from conditions that could interfere with vitamin D metabolism.

Occurrence and predictive factors of heterotopic ossification in severe acquired brain injured patients during rehabilitation stay: cross-sectional survey.

OBJECTIVES: To report occurrence and identify patient's features and risk factors of heterotopic ossifications in patients with severe acquired brain injury in intensive rehabilitation centres. DESIGN: Multicentre cross-sectional survey. SETTING: A total of 48 severe acquired brain injury rehabilitation institutes. PARTICIPANTS: Traumatic and non-traumatic severe brain-injured patients ( N = 689) in rehabilitation centres on 28 May 2016. MAIN OUTCOME MEASURE: Occurrence of heterotopic ossifications diagnosed by standard radiological and/or sonographic evaluation on the basis of clinical suspicion. RESULTS: Heterotopic ossification occurred around one or more joints in 94/689 patients (13.6%) with a significantly higher prevalence in young males. Occurrence did not significantly differ in relation to aetiology (16.3% traumatic, 19.2% anoxic, 11.7% vascular and 11.5% other). Prevalence was significantly higher in patients with diffuse (23.3%) rather than focal brain lesions (12.4%) or unspecified lesions (11.2%; chi-square = 7.81, df = 2, P = 0.020); longer duration of coma ( P = 0.0016) and ventilation support ( P = 0.0145); paroxysmal sympathetic hyperactivity (22.6% versus 11.6%; chi-square = 10.81, df = 1, P = 0.001); and spasticity (22.7% versus 10.1%; chi-square = 18.63, df = 1, P < 0.0001). A longer interval between acute brain injury and admission to rehabilitation centre was significantly associated with higher frequency of heterotopic ossifications. CONCLUSION: Occurrence of heterotopic ossifications is frequent in patients with severe traumatic and non-traumatic brain-injury in rehabilitation centres. Our study confirms male gender, young age, paroxysmal sympathetic hyperactivity, spasticity, longer duration of coma and ventilation and longer interval between brain injury onset and admission to rehabilitation centre as possible risk factors. Further studies are necessary to investigate the role of early appropriate rehabilitation pathways to reduce occurrence of heterotopic ossifications.

Neuropsychological testing.

Neuropsychological testing is a key diagnostic tool for assessing people with dementia and mild cognitive impairment, but can also help in other neurological conditions such as Parkinson's disease, stroke, multiple sclerosis, traumatic brain injury and epilepsy. While cognitive screening tests offer gross information, detailed neuropsychological evaluation can provide data on different cognitive domains (visuospatial function, memory, attention, executive function, language and praxis) as well as neuropsychiatric and behavioural features. We should regard neuropsychological testing as an extension of the neurological examination applied to higher order cortical function, since each cognitive domain has an anatomical substrate. Ideally, neurologists should discuss the indications and results of neuropsychological assessment with a clinical neuropsychologist. This paper summarises the rationale, indications, main features, most common tests and pitfalls in neuropsychological evaluation.

Modeling Alzheimer Disease Through Functional Independence and Participation.

INTRODUCTION: The relationship between cognitive and functional impairment in Alzheimer Disease (AD) at the earliest stages of the disease is not well characterized. This study aimed at investigating such relationships along AD evolution by means of the Disability Assessment for Dementia (DAD). METHODS: Consecutive pairs of AD outpatients and their primary informal caregivers were enrolled. Patients were evaluated by means of the Mini Mental State Examination and neuropsychological tests. A clinician completed the Clinical Dementia Rating Scale to stage dementia severity and interviewed the caregivers to complete the Neuropsychiatric Inventory to assess behavioral disturbances and the DAD to evaluate patients' functional competence. RESULTS: A total of 158 dyads were enrolled; the Mini Mental State Examination score was used to stratify patients into 4 groups (>24; 20 to 23.9; 10 to 19.9; <10) that were compared. The statistical analysis revealed that all the cognitive domains were positively related to functional independence, but only logical and executive functions seemed to predict autonomy. An intergroup comparison did not show significant differences in the DAD subscales measuring initiation, planning and organization, and performance. The role of education emerged, confirming the relevance of cognitive reserve. DISCUSSION: As the field moves toward earlier intervention in preclinical AD, the detection of early functional changes may drive the definition of trials on prevention or intervention for dementia.

Robotic-assisted gait training in Parkinson's disease: a three-month follow-up randomized clinical trial.

PURPOSE: The aim of this study was to evaluate the efficacy of a robotic-assisted gait training (RAGT), together with a conventional exercise program (CEP), to improve PD ambulation, as compared to standard gait training. METHODS: Thirty-eight patients with mild PD stage (H&Y 2-2.5) were randomly assigned to an experimental group (EG) or a control group. The 19 patients in EG received 30 min RAGT (using Lokomat device), whereas the 19 controls received a conventional gait training; both groups received 30 min of CEP. Participants were evaluated before (T0), immediately after (T1), and 12 weeks after the end of treatment (T2), by using 10-MWT, Tinetti Test and the motor score of the UPDRS-III. RESULTS: We found that Tinetti Walking (TW) (X2(3) = 31.75; p < 0.001), Tinetti Balance (X2(3) = 74.07; p < 0.001), UPDRS-III (X2(3) = 6.87; p < 0.001) and GDS (X2(3) = 28.83; p < 0.001) scores were affected by the type of the rehabilitative treatment. At T2, we found a significant difference between the two groups for TW (t = 2.62; p < 0.02, d = 0.85). Concerning all the study outcomes, a significant improvement was observed from T0 to T1 in both groups. However, the functional motor gain at T2 was maintained only in the EG. CONCLUSIONS: RAGT may significantly improve walking ability, motor function and for a maximum period of three months. Thus, our findings support the importance of a RAGT as a valid rehabilitative tool for PD.

Hospital-based register of stroke in the Molise Region: focus on main subtypes of stroke. Years 2009-2013.

We determined incidence and intra-hospital mortality rate of stroke in Molise, Italy, to provide information for planning regional healthcare facilities and to ameliorate stroke management in this region. This study is part of the "Rete Molisana dell'Ictus Cerebrale (REMOLIC)" study, a population-based Cerebrovascular Registry in Molise, from 2009 to 2013, with a cold pursuit approach. The crude annual incidence rates for total stroke per 100,000 inhabitants, notified by hospital discharge records, were 198 for 2009, 185 for 2010, 169 for 2011, and 176 for both 2012 and 2013. There was a significant decrease in risk in the years 2011-2013 [RR2011 vs. 2009: 0.85 (0.76-0.98), RR2012 vs. 2009: 0.89 (0.79-0.99), RR2013 vs. 2009: 0.89 (0.79-0.99)] as compared with 2009. For the year 2010, after adjustment to the Italian, European, and world populations, the overall incidence rates were 165, 134, and 67 per 100,000/year, respectively. Similar trends were found when men and women were analyzed separately. In the average, 20.8 % of subjects admitted for a cerebrovascular accident died during the hospitalization, among these 93.5 % in the first 28 days. The duration of hospital stay was constant in the years (2009-2012), except during 2013, where there was a significant decrease in the average (p < 0.001). Our study shows incidence rates decreasing from 2009 to 2013, while mortality rates were stable during the same years. This study underlines the need to plan better stroke management in Italy, in order to obtain outcomes more similar to those of the best performing countries.

Quality of life in Alzheimer disease: a comparison of patients' and caregivers' points of view.

Unlike in other chronic diseases, the Quality of Life (QoL) of patients affected by Alzheimer Disease (AD) has not been well established, primarily because of the difficulties stemming from the study of patients with cognitive disorders. Because no cure is currently available for AD, the optimization of QoL represents the best possible outcome attainable in all stages of disease, making QoL assessment mandatory. This study identified variables related to patients' QoL and examined the agreement between patients' and caregivers' QoL ratings. A total of 135 dyads (patient and principal caregiver) were enrolled in the study. Patients' QoL evaluations showed a negative relationship with depressive mood and a positive relationship with Activities of Daily Living (ADL), whereas caregivers' QoL ratings showed a negative relationship with patients' depressive mood and behavioral disturbances. Caregivers tended to underestimate patients' QoL compared with the patients' own self-evaluations, with patients' dependency in performing ADL and behavioral disorders as well as caregivers' burdens and depression being the main factors associated with the discrepancy in these evaluations. These findings suggest that the use of proxies as a substitute for the self-report of QoL data should be treated with caution, always accounting for the presence of potential bias.

A wearable system for visual cueing gait rehabilitation in Parkinson's disease: a randomized non-inferiority trial.

BACKGROUND: Gait disturbances represent one of the most disabling features of Parkinson's disease (PD). AIM: The aim of this study was to evaluate the non-inferiority of a new wearable visual cueing system (Q-Walk) for gait rehabilitation in PD subjects, compared to traditional visual cues (stripes on the floor). DESIGN: Open-label, monocentric, randomized controlled non-inferiority trial. SETTING: Outpatients. POPULATION: Patients affected by idiopathic PD without cognitive impairment, Hoehn and Yahr stage II-IV, Unified Parkinson's Disease Rating Scale motor section III ≥2, stable drug usage since at least 3 weeks. METHODS: At the enrollment (T0), all subjects underwent a clinical/functional evaluation and the instrumental gait and postural analysis; then they were randomly assigned to the Study Group (SG) or Control Group (CG). Rehabilitation program consisted in 10 consecutive individual sessions (5 sessions/week for 2 consecutive weeks). Each session included 60 minutes of conventional physiotherapy plus 30 minutes of gait training by Q-Walk (SG) or by traditional visual cues (CG). Follow-up visits were scheduled at the end of the treatment (T1) and after 3 months (T2). RESULTS: Fifty-two subjects were enrolled in the study, 26 in each group. The within-groups analysis showed a significant improvement in clinical scales and instrumental data at T1 and at T2, compared to baseline, in both groups. According to the between-group analysis, Q-Walk cueing system was not-inferior to the traditional cues for gait rehabilitation. The satisfaction questionnaire revealed that most subjects described the Q-Walk cueing system as simple, motivating and easily usable, possibly suitable for home use. CONCLUSIONS: Data showed that motor rehabilitation of PD subjects performed by means of the new wearable Q-Walk cueing system was feasible and as effective as traditional cues in improving gait parameters and balance. CLINICAL REHABILITATION IMPACT: Wearable devices can act as an additional rehabilitation strategy for long-term and continuous care, allowing patients to train intensively and extensively in household settings, favoring a tailor-made and personalized approach as well as remote monitoring.

Strategies adopted by cerebellar ataxia patients to perform U-turns.

Cerebellar ataxia is associated with unsteady, stumbling gait, and affected patients report a high rate of falls, particularly during locomotor tasks. U-turns (180° turns while walking) require a high level of coordination in order to completely reverse the body trajectory during ongoing motion, and they are particularly challenging for patients with cerebellar ataxia. The aim of this study was to investigate the kinematic strategies adopted by ataxic patients when performing U-turns. Nine ataxic patients and ten controls were analysed as they performed 180° turns to the right while walking. We evaluated the following aspects: centre of mass velocity, body rotation, number of steps needed to complete the task, step length and step width, lower limb joint kinematics and segmental reorientation. Compared with controls, the ataxic patients showed slower deceleration and re-acceleration of the body, needed more steps to complete the U-turn, showed markedly reduced step length and were unable to modulate step width between steps. Furthermore, the patients adopted an extended joint rather than a flexed joint turning strategy, and the degree of knee flexion was found to be negatively correlated with the number of falls. Ataxic patients show an abnormal U-turn in comparison to age-matched healthy subjects. Some of the observed alterations are indicative of a primary deficit in limb-joint coordination, whereas others suggest that patients choose a compensatory strategy aimed at reducing the instability.

Cognitive impairment in primary brain tumors outpatients: a prospective cross-sectional survey.

Brain tumors and anti-cancer treatments can cause a wide range of cognitive deficits that in turn, being a major cause of disability, significantly affect patients' independence and quality of life. To evaluate the neurocognitive status of a non selected population of brain tumors outpatients, investigating the correlation with clinical and demographic variables. This prospective cross-sectional survey enrolled consecutive outpatients with a histopathologically confirmed diagnosis of brain tumor. All the patients were evaluated with a battery of standardized neuropsychological tests assessing language, memory, logical-executive functions, attention, visuo-constructional abilities. An univariate regression analysis was performed to assess the impact of socio-demographical and clinical variables on the presence of cognitive impairment. 147 patients (61F/86M, mean age 52.8 ± 13.3, mean schooling 12.7 ± 4 were enrolled into the study. Out of the 147 patients evaluated, 80 (54.4 %) showed cognitive impairment: 43 (53.75 %) presented a multidomain impairment, while 37 (46.25 %) patients revealed cognitive deficits limited respectively to language (n:13, 16.25 %), memory (n:11, 13.75 %), attention (n:7, 8.75 %), logical-executive functions (n:5, 6.25 %), visuo-spatial abilities (n:1, 1.25 %). At the regression analysis the variables significantly related to the development of cognitive impairment were age (p = 0.04), lesion side (p = 0.00), chemotherapy (p = 0.03). As advances in anti-cancer treatment have prolonged life expectancy of neuro-oncological patients, standard clinical endpoints can't be limited to just survival or progression free survival, but have to consider clinical benefits on both motor and cognitive function and in general quality of life. Hence evaluation of new therapeutic strategies should routinely include longitudinal neuropsychological assessment.

Cognitive rehabilitation for early post-surgery inpatients affected by primary brain tumor: a randomized, controlled trial.

Cognitive impairment is one of the most common neurological disorders in neuro-oncological patients and exerts a deep negative impact on quality of life interfering with familiar, social and career-related activities. To test the effectiveness of early cognitive rehabilitation treatment for inpatients affected by primary brain tumors. Out of 109 consecutive patients enrolled in the study, 58 patients were randomly assigned to a rehabilitation group or to a control group. The rehabilitation consisted of 16 one-hour individual sessions of therapist-guided cognitive training, spread over 4 weeks, combining computer exercises and metacognitive training. Patients in the control group received usual care without cognitive training. All patients were evaluated by means of a comprehensive neuropsychological battery at the admission (T0) and after 4 weeks (T1). Patients in the rehabilitation group showed a significant improvement of cognitive functions. In particular, the domains that benefited most from the training were visual attention and verbal memory. The control group exhibited only a slightly, not statistically relevant, enhancement of cognitive performances. Cognitive rehabilitation for neuro-oncological inpatients resulted in a significant enhancement of cognitive performances after the training, also providing a foundation for early administration. Future research should be aimed to clarify the patients' characteristics that predict neuropsychological improvement, to identify the most effective elements in rehabilitative programs and to study the effects of treatment extension to everyday life.

Botulinum Toxin-A High-Dosage Effect on Functional Outcome and Spasticity-Related Pain in Subjects with Stroke.

Stroke patients can develop spasticity and spasticity-related pain (SRP). These disorders are frequent and can contribute to functional limitations and disabling conditions. Many reports have suggested that higher doses than initially recommended of BTX-A can be used effectively and safely, especially in the case of severe spasticity; however, whether the treatment produces any benefit on the functional outcome and SRP is unclear. Studies published between January 1989 and December 2022 were retrieved from MEDLINE/PubMed, Embase, and Cochrane Central Register. Only obabotulinumtoxinA (obaBTX-A), onabotulinumtoxinA, (onaBTX-A), and incobotulinumtoxinA (incoBTX-A) were considered. The term "high dosage" indicates ≥600 U. Nine studies met the inclusion criteria. Globally, 460 subjects were treated with BTX-A high dose, and 301 suffered from stroke. Studies had variable method designs, sample sizes, and aims. Only five (55.5%) reported data about the functional outcome after BTX-A injection. Functional measures were also variable, and the improvement was observed predominantly in the disability assessment scale (DAS). SRP pain was quantified by visual analog scale (VAS) and only three studies reported the BTX-A effect. There is no scientific evidence that this therapeutic strategy unequivocally improves the functionality of the limbs. Although no clear-cut evidence emerges, certain patients with spasticity might obtain goal-oriented improvement from high-dose BTX-A. Likewise, data are insufficient to recommend high BTX dosage in SRP.

Early rehabilitation after surgery improves functional outcome in inpatients with brain tumours.

Clinical experience suggests that application of the fundamental principles of rehabilitation medicine can improve the care of patients with cancer. Despite the high incidence of neurological and functional deficits in patients affected by brain tumours (BTs), rehabilitation treatment of this population is not as well established as it is for patients with other neurological conditions. To assess functional outcome in brain tumour inpatients who underwent early rehabilitation after surgery. 75 patients who had undergone neurosurgery for primary BTs and 75 patients affected by stroke were enrolled in a case-control study. All patients were evaluated by means of a core set of clinical scales (Functional Independence Measure, Sitting Balance score, Standing Balance score, Hauser Index, Massachusetts General Hospital Functional Ambulation Classification). Patients were evaluated before the beginning (T0) and at the end (T1) of rehabilitation treatment. The neurorehabilitation programme consisted of individual 60-min sessions of treatment, administered once a day, six days a week, for four consecutive weeks. Speech therapy was included when aphasia was diagnosed. All the measures of outcome were indicative of substantial improvements for neuro-oncological and for stroke patients (P = 0.000). Analysis of subgroups showed that patients affected by meningioma achieved better results (in efficiency terms) as regards independence in activities of daily living (P = 0.02) and mobility (P = 0.04) compared with patients affected by glioblastoma or stroke. Rehabilitation after surgery can improve functional outcome, justifying the delivery of rehabilitation services, even during the acute phase, to BTs inpatients, irrespective of tumour type.

Caregiver burden and coping in early-stage Alzheimer disease.

This study was set out to describe caregiver-perceived burden and coping in early-stage Alzheimer disease (AD). A total of 163 consecutive pairs of patients with AD and their principal caregivers were initially recruited. The caregivers completed the Caregiver Burden Inventory (CBI) and the Coping Orientations to Problems Experienced scale, and also provided sociodemographic information; the patients with AD were assessed by means of the Mini Mental State Examination and the Neuropsychiatric Inventory. Data from 126 patient-caregiver pairs were analyzed. The caregivers (mean age 56.11±12.37 y) were mainly women (76%); 64% were the patient's offspring; 39% lived with the patient. From the CBI data, it emerged that caregivers perceived loss of personal time (objective burden, 33%) and the feeling of missing out on opportunities (developmental burden, 25%) as their main stressors. Total CBI score was negatively correlated with Mini Mental State Examination (P=0.005). As regards coping strategies, the caregivers predominantly used problem-oriented strategies associated with a positive attitude. The use of dysfunctional strategies was predictive of caregiver burden. It is important to be aware that avoidance and dysfunctional coping strategies predispose caregivers of patients with AD to higher level of distress, whereas successful caregiving seems to be based on the use of problem-oriented strategies early in the disease when solutions are still available.
