Rehabilitative devices for a top-down approach
In recent years, neurorehabilitation has moved from a "bottom-up" to a "top down" approach. This change has also involved the technological devices developed for motor and cognitive rehabilitation. It implies that during a task or during therapeutic exercises, new "top-down" approaches are being used to stimulate the brain in a more direct way to elicit plasticity-mediated motor re-learning. This is opposed to "Bottom up" approaches, which act at the physical level and attempt to bring about changes at the level of the central neural system. Areas covered: In the present unsystematic review, we present the most promising innovative technological devices that can effectively support rehabilitation based on a top-down approach, according to the most recent neuroscientific and neurocognitive findings. In particular, we explore if and how the use of new technological devices comprising serious exergames, virtual reality, robots, brain computer interfaces, rhythmic music and biofeedback devices might provide a top-down based approach. Expert commentary: Motor and cognitive systems are strongly harnessed in humans and thus cannot be separated in neurorehabilitation. Recently developed technologies in motor-cognitive rehabilitation might have a greater positive effect than conventional therapies
Predictors of progression of cognitive decline in Alzheimer’s disease: the role of vascular and sociodemographic factors
Rates of disease progression differ among patients with Alzheimer’s disease, but little is known about prognostic predictors. The aim of the study was to assess whether sociodemographic factors, disease severity and duration, and vascular factors are prognostic predictors of cognitive decline in Alzheimer’s disease progression. We conducted a longitudinal clinical study in a specialized clinical unit for the diagnosis and treatment of dementia in Rome, Italy. A total of 154 persons with mild to moderate Alzheimer’s disease consecutively admitted to the dementia unit were included. All patients underwent extensive clinical examination by a physician at admittance and all follow-ups. We evaluated the time-dependent probability of a worsening in cognitive performance corresponding to a 5-point decrease in Mini-Mental State Examination (MMSE) score. Survival analysis was used to analyze risk of faster disease progression in relation to age, education, severity and duration of the disease, family history of dementia, hypertension, hypercholesterolemia, and type 2 diabetes. Younger and more educated persons were more likely to have faster Alzheimer’s disease progression. Vascular factors such as hypertension and hypercholesterolemia were not found to be significantly associated with disease progression. However, patients with diabetes had a 65% reduced risk of fast cognitive decline compared to Alzheimer patients without diabetes. Sociodemographic factors and diabetes predict disease progression in Alzheimer’s disease. Our findings suggest a slower disease progression in Alzheimer’s patients with diabetes. If confirmed, this result will contribute new insights into Alzheimer’s disease pathogenesis and lead to relevant suggestions for disease treatment
The Role of Immersive Virtual Reality Interventions in Pediatric Cerebral Palsy: A Systematic Review across Motor and Cognitive Domains
Background: In recent years, new technologies have been applied in cerebral palsy. Among these, immersive virtual reality is one with promising motor and cognitive effects along with the reduced costs of its application. The level of immersion of the subject in the illusional world gives the feeling of being a real part of the virtual environment. This study aims to investigate the safety and the efficacy of immersive virtual reality in children affected by cerebral palsy. Methods: PubMed, Embase, Cochrane Database of Systematic Reviews, RehabData, and Web of Science were screened up to February 2023 to identify eligible clinical studies. Results: Out of 788, we included 15 studies involving CP patients. There was high heterogeneity in the outcomes considered, and the results showed non-inferiority to conventional therapy and initial additional benefits in comparison with conventional rehabilitation. Conclusions: Immersive virtual reality emerges as a pivotal technological tool in rehabilitation, seamlessly integrating with conventional therapy within CP rehabilitation programs. Indeed, it not only enhances motivation but significantly increases children’s functional capacity and abilities
Chronic Pain in the Elderly with Cognitive Decline: A Narrative Review
The presence of pain in elderly persons with cognitive decline is often neglected, under-reported, underestimated, misdiagnosed and not adequately treated, with consequences that have a strong impact on health, independence in activities of daily living and quality of life. There is no empirical evidence that people with dementia experience less pain; therefore, in patients with severe cognitive impairment the progression of cognitive decline dramatically affects the ability to verbalize the presence of pain. Self-assessment scales are considered the "gold standard" for pain assessment, but the presence of cognitive impairment is likely to reduce the reliability of these measures. Treatment of pain in elderly with cognitive decline or dementia is based on non-pharmacological and pharmacological strategies. Pharmacological treatment should consider physiological changes, high comorbidity and drug interactions that occur frequently in the elderly. This narrative review aims to describe current knowledge, methods of detection and treatment approaches for chronic pain in elderly persons with cognitive deficits
Facial emotion recognition deficit in Amnestic Mild Cognitive Impairment and Alzheimer Disease
Objectives: A deficit in facial emotion recognition was described in patients with Alzheimer disease ( AD). However, this issue has been underexplored in subjects with amnestic mild cognitive impairment ( a- MCI). Thus, the authors aimed to determine whether a deficit in facial emotion recognition is present in a- MCI phase and whether this is intensity dependent. A secondary aim was to investigate relationships between facial emotion recognition and cognitive performances. Design: Case-control study. Setting: Memory clinic. Participants: Fifty a- MCI patients, 50 mild AD patients, and 50 comparison subjects ( COM) were enrolled. Measurements: Information about facial emotion recognition was obtained from Penn Emotion Recognition Test. The Mental Deterioration Battery was used to measure cognitive impairment. Results: Mild AD patients were more impaired in the recognition of almost all emotional stimuli of all intensities than a- MCI and COM subjects. However, there was an increased progression only in lowintensity facial emotion recognition deficit from COM to a- MCI to mild AD patients. In particular, a- MCI subjects differed significantly from COM in low-intensity fearful face recognition performance. This deficit in a- MCI patients was explained by the short-term verbal memory impairment, whereas the same deficit in mild AD patients was explained by the long-term verbal memory impairment. Conclusions: Emotion recognition progresses from a deficit in low-intensity fearful facial recognition in a- MCI phase to a deficit in all intensities and emotions in mild AD. This could be an effect of the progressive degeneration of brain structures modulating emotional processing. An early detection of emotional impairment in MCI phases of dementia may have clinical implications
Interleukin 18 gene polymorphisms predict risk and outcome of Alzheimer's disease
Inflammation has been extensively implicated in the pathogenesis of Alzheimer's disease (AD). Although there is evidence of a key role for cytokines in neuroinflammation processes, so far the proinflammatory cytokine interleukin (IL)-18 has not been associated with AD. The aim of this study was to investigate the impact of two polymorphisms of the human IL-18 gene promoter at positions -607 (C/A) and -137 (G/C) on both susceptibility to and progression of AD
Computer-assisted cognitive rehabilitation in neurological patients:state-of-art and future perspectives
Background and aim: Advances in computing technology enabled researchers and clinicians to exploit technological devices for cognitive training and rehabilitation interventions. This expert review aims to describe the available software and device used for cognitive training or rehabilitation interventions of patients with neurological disorders. Methods: A scoping review was carried out to analyze commercial devices/software for computerized cognitive training (CCT) in terms of feasibility and efficacy in both clinical and home settings. Several cognitive domains responding to the different patients’ needs are covered. Results: This review showed that cognitive training for patients with neurological diseases is largely covered by several devices that are widely used and validated in the hospital setting but with few translations to remote/home applications. It has been demonstrated that technology and software-based devices are potential and valuable tools to administer remotely cognitive rehabilitation with accessible costs. Conclusion: According to our results, CCT entails the possibility to continue cognitive training also in different settings, such as home, which is a significant breakthrough for the improvement of community care. Other possible areas of use should be the increase in the amount of cognitive therapy in the free time during the hospital stay.</p
