Abstract
Background-Purpose: Low serum vitamin D (VD) has been already associated with a series of highly prevalent pain-related conditions, including fibromyalgia, migraine and chronic widespread pain. Considering the potential interplay between VD and pain signalling pathways, the association of VD with tension-type headache (TTH) was reviewed. Methods: A multifaceted narrative approach assessing the relationship of serum VD with TTH and TTH parameters, as well as the efficacy of VD supplementation for the prevention of TTH, was fostered. MEDLINE, CENTRAL and EMBASE were comprehensively searched for this purpose, while Google Scholar was also explored according to a structured approach. ClinicalTrials.gov and European Union Clinical Trials Register were explored for ongoing prevention trials. Results: Although available evidence was suggestive of an association between VD and TTH, mainly of the chronic type, the causal nature of the association remains to be determined. Considering the lack of longitudinal evidence, this relationship could arguably reflect behavioural patterns of headache sufferers. On the other hand, evidence principally originated from tertiary clinical settings (severe comorbidity burden) and researchers tend to report a concomitant association of both entities with generalized musculoskeletal compromise. In this context, the association between TTH and VD may represent nothing more than a secondary by-product of the simultaneous relationship of other comorbid diseases-conditions with both TTH and low serum VD. Regarding its efficacious properties, only one ongoing trial specifically designed to explore the efficacy of VD in chronic TTH in adults was retrieved. Conclusions: There is no evidenced based indication for VD supplementation in TTH.

Abstract
In addition to motor symptoms, neurocognitive impairment (NCI) affects patients with prodromal Parkinson's disease (PD). NCI in PD ranges from subjective cognitive complaints to dementia. The purpose of this review is to present the available evidence of NCI in PD and highlight the heterogeneity of NCI phenotypes as well as the range of factors that contribute to NCI onset and progression. A review of publications related to NCI in PD up to March 2023 was performed using PubMed/Medline. There is an interconnection between the neurocognitive and motor symptoms of the disease, suggesting a common underlying pathophysiology as well as an interconnection between NCI and non-motor symptoms, such as mood disorders, which may contribute to confounding NCI. Motor and non-motor symptom evaluation could be used prognostically for NCI onset and progression in combination with imaging, laboratory, and genetic data. Additionally, the implications of NCI on the social cognition of afflicted patients warrant its prompt management. The etiology of NCI onset and its progression in PD is multifactorial and its effects are equally grave as the motor effects. This review highlights the importance of the prompt identification of subjective cognitive complaints in PD patients and NCI management.

Abstract
Although language impairment is frequently observed in patients with Alzheimer's disease (pwAD), targeted language rehabilitation is often overlooked. The present study reviews published evidence on the impact of language training, either alone or in combination with cognitive training, on cognitive outcomes in pwAD. A systematic search of PubMed, Google Scholar, and Cochrane was carried out, including studies published from inception to November 2023. A total of eight research articles (four randomized controlled trials and four observational studies) met the inclusion criteria: six assessed language training combined with cognitive training and two evaluated language rehabilitation alone. Regarding language and non-language (mainly memory, attention, and executive functions) outcomes, there was a consensus among studies that language rehabilitation (alone or in combination with cognitive training) yields positive results. Some of the articles also explored the impact on patients' and their caregivers' quality of life, with all but one showing improvement. Consequently, the combination of language and cognitive training leads to improvements across various cognitive domains. However, limited evidence supports the value of sole language rehabilitation. This conclusion is influenced by heterogeneity among studies (different types and duration of interventions, small participant sets, various assessment tools), and, thus, further research is warranted.

Abstract
OBJECTIVE The aim of the present study was to validate the Communication and Language Assessment questionnaire for persons with Multiple Sclerosis (CLAMS) into the Greek language. METHOD 106 Persons with Multiple Sclerosis (PwMS) and 51 healthy controls (HCs) participated in this study. We evaluated patients' cognitive abilities with the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS). All PwMS completed the CLAMS and three additional questionnaires (Speech Pathology-Specific Questionnaire for persons with Multiple Sclerosis, SMS; Stroke and Aphasia Quality of Life Scale-39, SAQOL-39; the Beck Depression Inventory Fast Screen, BDI-FS), and all HCs filled in the CLAMS. RESULTS The internal consistency of the CLAMS was excellent (a = 0.933) for the PwMS and a significant difference was found between PwMS and HCs for the total CLAMS score. Statistical analyses showed a significant positive correlation between the CLAMS and the other questionnaires (SMS, BDI, and SAQOL-39) and a statistically significant negative correlation between the CLAMS and the three subtests of the BICAMS (Symbol Digit Modalities Test, Greek Verbal Learning Test-II, and Brief Visuospatial Memory Test-Revised). There was no correlation between the CLAMS and participants' age, disease duration, and disease type. CONCLUSION The Greek version of the CLAMS is a valid self-reported questionnaire for the evaluation of language and communication symptoms in PwMS.

Abstract
PURPOSE The aim of the present study was to adapt and validate the Speech Pathology-Specific Questionnaire for Persons with Multiple Sclerosis (SMS) into the Greek language. METHOD The study sample consisted of 124 people with multiple sclerosis (PwMS) and 50 healthy controls (HCs). All PwMS underwent cognitive assessment using the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS). Both PwMS and HCs completed the SMS, the Eating Assessment tool (EAT-10), the Voice Handicap Index (VHI), and the Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39). RESULT Significant difference was found between PwMS and HCs for the EAT-10, SAQOL-39, the total SMS, and the SMS subscales. Discriminant validity analyses revealed a statistically significant difference between PwMS and HCs for the total and subscales SMS. Convergent validity analyses between the total SMS and the SMS subscales, and scores on the BICAMS, EAT-10, SAQOL-39, and VHI in PwMS were significantly correlated, with exception of the SMS Speech/Voice with the Symbol Digit Modalities Test (SDMT) and the Greek Verbal Learning Test-II (GVLT-II). Scores on the EAT-10, SAQOL-39, and VHI in PwMS were also correlated with the total SMS and the SMS subscales in PwMS, HCs, and the total sample. Construct validity analyses revealed that the total SMS and the SMS subscales were significantly correlated with the Expanded Disability Status Scale (EDSS) and years of education, while no associations were found with regards to age, MS subtype (relapsing-remitting MS [RRMS] vs progressive MS [PMS]), disease duration, or sex. The internal consistency of all items was excellent in PwMS and the total sample (Cronbach's alpha was >0.7 after deletion of one item), with the exception of two items, which still fell within the acceptable range (>0.6) for PwMS and the total sample. CONCLUSION The Greek version of the SMS is a reliable and valid patient-reported outcome measure to assess speech-language and swallowing pathology related symptoms in PwMS, and can be used for research and clinical purposes.

Abstract
The recent coronavirus emergency raised the question of whether telerehabilitation could be as effective as conventional face-to-face intervention. The aim of the present study was to compared language and cognitive training delivered to patients from a distance, through telecommunication systems, for the same intervention conducted on a face-to-face mode in patients with multi domain amnestic MCI (md-aMCI). To this end, 30 patients diagnosed with md-aMCI took part in the present study. The participants divided into two groups; one group received conventional face-to-face training and the other group received Telerehabilitation training. Both groups received language training using paper and pencil tasks and cognitive training using the Rehacom software. The training lasted 15 weeks and was delivered twice a week, for 60 minutes per session. The conventional face-to-face mode had a significant impact on cognitive (delayed and working memory, processing speed, executive function, and attention) and language domains (naming, word recognition, and semantic fluency). The telerehabilitation method had a beneficial impact on delayed memory, naming, and semantic fluency. The results of our study provide evidence that both telerehabilitation and face-to-face language and cognitive training seem to have a positive impact in patients with md-aMCI, with face-to-face training improving more domains than telerehabilitation.

Abstract
BACKGROUND Microglial activation is considered to assume a role in the pathogenesis of Amyotrophic Lateral Sclerosis (ALS). To date, the relationship between ALS and the rs3865444 polymorphism of the cluster of differentiation 33 (CD33) has not been explored. The current report aimed to investigate the potential connection between CD33 rs3865444 and ALS. METHODS Patients diagnosed with sporadic ALS according to the revised El Escorial criteria, as well as age and sex matched community controls, were enrolled. Two evenly numbered, age and sex matched groups of 155 participants each were genotyped. RESULTS No association was found between rs3865444 and ALS [log-additive odds ratio (OR) = 0.83 (0.57, 1.22), over-dominant OR = 0.86 (0.55, 1.36), recessive OR = 0.73 (0.25, 2.17), dominant OR = 0.82 (0.52, 1.29), co-dominant OR1 = 0.68 (0.23, 2.05) and co-dominant OR2 = 0.84 (0.53, 1.33)]. Moreover, no relationship was established between rs3865444 and the age of ALS onset based on both unadjusted and sex adjusted Cox-proportional hazards models. Finally, no association between rs3865444 and ALS was found in subgroup analyses based on the site of ALS onset (bulbar or spinal) and sex. CONCLUSIONS The current analysis is the first to report that rs3865444 is not linked to ALS. Larger multi-racial studies are required to confirm these findings.

Abstract
Previous studies have reported that widely used tests for aphasia identification are unable to detect the subtle language deficits of left hemisphere brain damaged (LHBD) individuals. Similarly, the language disorders of individuals with right hemisphere brain damage (RHBD) usually remain undetected, due to the lack of any specialized test for the evaluation of their language processing skills. The aim of the present study was to evaluate the language deficits of 80 individuals suffering from the effects of either a LHBD or RHBD stroke, who were diagnosed as having no aphasia or language deficits based on the application of Boston Diagnostic Aphasia Examination. Their language abilities were examined with the use of the Adults' Language Abilities Test, which explores morpho-syntactic and semantic phenomena of the Greek language in both the comprehension and production modalities. Results revealed that both groups of stroke survivors performed significantly worse compared to the group of healthy participants. Thus, it appears that the latent aphasia of LHBD and the language deficits of RHBD patients are likely to remain undetected and that patients are at risk of not receiving appropriate treatment if their language abilities are not evaluated by an effective and efficient battery of language tests.

Abstract
BACKGROUND The role of temporal lobe epilepsy (TLE) in determining personality traits and neurobehavioral symptoms, collectively known as the interictal behavioral syndrome (also known as Geschwind syndrome or "Gastaut-Geschwind syndrome"), as well as the syndrome's association with the particular artistic expression of many epileptic litterateurs are well known in neurology and psychiatry. A deepening of emotionality along with a serious, highly ethical, and spiritual behavior have been described as positive personality changes among patients with chronic mesial-TLE. OBJECTIVES Our narrative-based clinical hypothesis aims at contributing to the ongoing debate on the association between TLE and artistic expression, as well as the latter's supposed implication for epileptology in general and the neuropsychology of epilepsy in particular. METHODS Through an analysis of the biography, language, and literary work of Greek novelist Demosthenes Voutyras, we hypothesize that his mystical and dark writing style could be attributed to medial temporal interictal dynamics. CONCLUSIONS We suggest that the psycholiterary profile of Voutyras is consistent with the idiosyncratic characteristics of the temporal lobe personality, while a non-dominant temporal lobe contribution has been proposed.

Abstract
OBJECTIVE The aim of the present study was to investigate the efficacy and feasibility of a telerehabilitation program in multi-domain amnestic Mild Cognitive Impairment (md-aMCI). The study sample consisted of 30 patients with md-aMCI and aged 60-80 years. METHODS The participants were randomly divided into two groups. The Training Group (TG), which received cognitive training by using the RehaCom software as well as paper-pencil language training and the Control Group (CG) which received standard clinical care (e.g., psychotherapy or/and physiotherapy). Duration of the telerehabilitation intervention was 15 weeks (twice a week for 60 min/session). RESULTS Our results revealed that the neuropsychological performance of the TG group after the telerehabilitation intervention improved on a statistically significant level on the domains of delayed and working memory, confrontation naming, verbal fluency, and global cognition. Comparison between the TG and CG revealed a significant impact of the telerehabilitation program on the domains of memory (delay and working) and language (naming and verbal fluency) as well as global cognition performance. CONCLUSION The findings of the study are promising in that the telerehabilitation intervention appears to be a useful method in improving or stabilizing cognitive decline in md-aMCI individuals and was a particularly effective alternative approach during the period of the pandemic lockdown. Specifically, the beneficial impact of the telerehabilitation intervention on episodic memory (which is one of the first domains to show impairment in md-aMCI patients) provides us with hope and evidence that these types of interventions may be applied with similar success using face-to-face interventions.

Abstract
Primary progressive aphasia (PPA) is a gradually progressive clinical syndrome in which the first and predominant symptoms involve language and/or speech production that interfere with daily activities. Transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) appear to have a beneficial impact on many neurodegenerative pathologies. The current review investigated the impact of rTMS and tDCS on PPA patients. English language articles that have been published in the databases PubMed, and Scopus from 2007 to 2022 were included. Fifteen single-case or small-group studies were analyzed and presented. The majority of the literature findings point toward that the application of rTMS or tDCS may have a positive effect in improving symptoms such as verb production, action naming, phonemic-verbal fluency, grammatical comprehension, written spelling, and semantic features. In conclusion, our review provides additional evidence supporting that both types of stimulation may improve linguistic deficits, especially if they combined, speech therapy.

Abstract
OBJECT Νeuropsychological assessment is particularly important for the accurate discrimination of cognitive abilities and weaknesses of patients in order to determine the appropriate therapeutic intervention. However, the reliability and validity of neuropsychological assessment appears to be influenced by a wide range of factors, including literacy and educational level. AIM This systematic review evaluates neuropsychological tests appropriate for the valid assessment of illiterate individuals and the effectiveness of cognitive rehabilitation programs for illiterate and/or low-educated individuals according to the results of English language studies that have been published in the PubMed/Medline electronic database until August 2022 (no initiation date). RESULTS 49 studies were included for neuropsychological assessment and 4 studies for cognitive rehabilitation. In terms of investigating the validity and reliability of neuropsychological tests for the assessment of healthy illiterate individuals, most studies concluded that for the majority of neuropsychological tests there is a significant difference in performance between healthy illiterate and literate individuals. However, there was consensus among studies that the performance of illiterate subjects was equivalent to the performance of literate subjects on tasks depicting colored and real objects. Regarding cognitive rehabilitation programs, all four studies concluded that they are effective in improving the cognitive functions of illiterate and/or low-literate patients with mild cognitive impairment and/or mild dementia. CONCLUSIONS For the assessment of illiterate individuals, it is imperative that neuropsychological tests with high ecological validity (i.e., tests related to activities of daily living) be administered so as not to underestimate their cognitive functioning. At the same time, cognitive enhancement/stimulation programs seem to be effective in this population group; however, this area needs further investigation.

Abstract
OBJECTIVE Antipsychotic drugs constitute the basis of schizophrenia therapy; however, available pharmaceutical agents lack efficacy for treating the cognitive deficits caused by the illness. The aim of the present work is to present current data regarding cognitive rehabilitation of schizophrenia, providing information and guidance to health professionals. METHOD A literature search was conducted in the PubMed and Google Scholar Databases from inception up to 1/9/2022. Relevant articles were explored for factors affecting cognitive function, including genetics, psychopathology, time in the course of the illness, and drug therapy. Characteristics and outcome of cognitive rehabilitation programs are briefly presented. RESULTS A total of 562 relevant articles were retrieved, 39 of which were selected for the review. Factors contributing to a favorable outcome are young age, early phase of disease, symptomatic control of hostility and conceptual disorganization, lack of negative symptoms, management of drug side effects, and cognitive and cortical reserve. Some evidence for a procognitive effect seems to exist for atypical antipsychotics, clozapine, aripiprazole, memantine, modafinil, d-serine, and cycloserine. The Val/Val polymorphism of the COMT gene seems to be associated with worse outcome. Specific remediation strategies include programs such as Cognitive Enhancement Therapy (CET), Cognitive Adaptation Training (CAT), and RehaCom Cognitive Therapy Software, among others, all employing a range of techniques, from paper-and-pencil to computer-assisted, bottom-up, or top-down approaches, and varying neurocognitive targets. CONCLUSION Cognitive symptoms, closely related to functional impairment, still remain a therapeutic challenge. Cognitive rehabilitation strategies are as yet the only treatment modality offering cognitive improvement to patients who struggle to recover.

Abstract
OBJECTIVE Aphasia is a serious consequence of stroke resulting in difficulties in using language for communication with negative effects on patients' quality of life. The use of non-invasive repetitive transcranial magnetic stimulation (rTMS) is a novel approach in aphasia therapy, based on the knowledge gained by functional imaging technics of the brain. AIM This review evaluates the effectiveness of rTMS on aphasia therapy according to the results of English language studies that have been published in the databases PubMed/Medline, Scopus, and Web of Science from 2011 to 2021. RESULTS Twenty-seven studies were included in the review with 672 participants. The studies mainly concern the application of inhibitory rTMS on the right inferior frontal gyrus (rIFG) in the subacute and chronic phase, as well as excitatory rTMS of the unaffected language areas of the left cerebral hemisphere in the chronic phase after stroke. Most of the studies concluded that there was statistically significant improvement in various parameters of language including confrontation naming, repetition, and aphasia quotient. Three studies published results that doubt the effectiveness of rTMS. CONCLUSION rTMS is a safe therapeutic method for aphasia treatment in the subacute and chronic phases after stroke. Its effectiveness is immediate as well as distant with a gradually decreasing therapeutic effect. Moreover, rTMS may supplement speech and language therapy as a priming factor. The most recognized method at this point in time is the application of suppressive rTMS on the right inferior frontal gyrus in combination with speech and language therapy.

Abstract
OBJECTIVE Epilepsy patients could possibly benefit from the remuneration observed in the use of virtual reality (VR) and virtual environments (VEs), especially in cognitive difficulties associated with visuospatial navigation (memory, attention, and processing speed). AIM Research questions under consideration in the present systematic review are associated to VEs' efficiency as a cognitive rehabilitation practice in epilepsy and the particular VR methods indicated for epilepsy patients. To meet criteria, studies included participants suffering from any form of epilepsy and a methodological design with a structured rehabilitation program/model. Data were collected online, using academic databases. RESULTS Fourteen studies were included in the literature review and 6 in the statistical analysis. ROBINS-I protocol was implemented to assess the risk of bias. An inverse variance analysis (random effects) of pooled estimates of differences was implemented, in the form of continuous data. Despite the heterogeneity of the studies, all of them agree on the beneficial aspects of VR and VEs in cognitive rehabilitation in relation to visuospatial memory, attention, and information processing speed. CONCLUSION We suggest that patients suffering from epilepsy may benefit from the use of VR cognitive rehabilitation interventions, concerning visuospatial memory, attention, and information processing speed. However, further investigation is needed in order to gain a better understanding of the mechanisms involved in cognitive rehabilitation via VEs and establish efficient and dynamic rehabilitation protocols.

Abstract
Non-invasive brain stimulation (NIBS) has emerged as one of the methods implemented in stroke rehabilitation. Cerebellar stimulation has gained research interest as an alternative strategy to cortical stimulation, based on the role of the cerebellum and corticocerebellar tracts in different motor and cognitive functions. This review investigates the role of the cerebellum in motor and cognitive rehabilitation following cerebral stroke using NIBS techniques combined with other therapies (e.g., speech or physical therapy). Fifteen randomized clinical trials were included. The majority of the literature findings point towards the cerebellum as a promising neurostimulation target following stroke of the cerebral cortex. Findings concern mostly rehabilitation of gait and balance, where cathodal transcranial direct current stimulation (tDCS) and intermittent theta-burst stimulation (iTBS) of the contralesional cerebellar hemisphere produce, in the presented clinical sample, improved performance and plasticity changes in the corticocerebellar network, combined with other rehabilitation methods. Data regarding aphasia rehabilitation are scarce, with right cerebellar tDCS exercising some impact in individual linguistic functions combined with language therapy. Based on recent data concerning cerebellar functions and corticocerebellar networks, along with the development of clinical protocols regarding non-invasive cerebellar (NICS) application, the cerebellum can prove a crucial intervention target in rehabilitation following stroke.

Abstract
Investigations of affective prosodic processing have demonstrated a decline with aging. It is unclear, however, whether this decline affects all or specific emotions. Also, little is known about the ability of syntactic resolution ambiguity with the use of prosody in aging. Twenty older (age range = 70-75) and 20 younger adults (age range = 20-25) performed an affective (happiness, neutrality, sadness, surprise, fear, and anger) and a linguistic (subject/object ambiguities) prosody task. Relative to young participants, older participants faced difficulty decoding affective prosody, particularly negative emotions, and syntactic prosody, in particular the subject reading condition. A marginally positive correlation was found between the affective and syntactic prosody tasks in the group of older individuals, but no gender differences in either prosodic task. The findings of the affective prosody task are discussed under the prism of the Socioemotional Selectivity Theory, whereas general parsing strategies can account for the preference for the object reading condition.

Abstract
We report a patient with a chronic subdural/epidural hematoma superimposed to a large arachnoid cyst occupying the left frontotemporal region. Both were discovered accidentally because of a trigeminal neuralgia and concomitant subjective memory complaints. Patient's sudden selective audioverbal memory impairment probably links to a primary cortical tone deregulation and expressed through deficits of arousal-mediating structures subtly impacted by the hematoma's progression. This case illustrates that in early-onset asymmetrical brain damage (usually left), language, audioverbal memory in particular, should not always come to dominate intact hemisphere function. A severity-threshold may exist below which inter-hemispheric reorganization of audioverbal memory is unlikely.

Abstract
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease. Through a genome‑wide association study (GWAS), the Sec1 family domain‑containing protein 1 (SCFD1) rs10139154 variant at 14q12 has emerged as a risk factor gene for ALS. Moreover, it has been reported to influence the age at onset (AAO) of patients with ALS. The aim of the present study was to assess the association of the SCFD1 rs10139154 polymorphism with the risk of developing ALS. For this purpose, 155 patients with sporadic ALS and 155 healthy controls were genotyped for the SCFD1 rs10139154. The effect of the SCFD1 rs10139154 polymorphism was then examined on the following parameters: i) The risk of developing ALS; ii) the AAO of ALS; iii) the site of ALS onset (patients with bulbar onset ALS vs. healthy controls; and patients with limb onset ALS vs. healthy controls); and iv) the AAO of ALS onset with subgroup analyses based on the site of onset (bulbar and limb, crude and adjusted for sex). The analysis of all the outcomes was performed assuming five genetic models. Crude and adjusted analyses were applied. The threshold for statistical significance was set at 0.05. The results revealed no association between SCFD1 rs10139154 and any of the examined phenotypes in any of the models examined. On the whole, based on the findings of the present study, SCFD1 rs10139154 does not appear to play a determining role in the risk of developing ALS.

Abstract
We present an update of the literature concerning long-term neuropsychological outcomes following surgery for refractory temporal lobe epilepsy (TLE). A thorough search was conducted through the PubMed and Medline electronic databases for studies investigating neuropsychological function in adult patients undergoing resective TLE surgery and followed for a mean/median > five years period. Two independent reviewers screened citations for eligibility and assessed relevant studies for the risk of bias. We found eleven studies fulfilling the above requirements. Cognitive function remained stable through long-term follow up despite immediate post-surgery decline; a negative relation between seizure control and memory impairment has emerged and a possible role of more selective surgery procedures is highlighted.

Abstract
Depersonalization is a dissociative disorder associated to a profound disruption of self-awareness in the form of emotional numbing and feelings of disembodiment. The salient feature of depersonalization is a breakdown in the familiarity of one's psychological and somatic self (and surroundings when derealization is also present), in spite of being aware of the unreality of the change. At an early stage of research it was realized that people inclined to dissociation find it harder to tolerate discontinuity in perceptual environments, possibly due to a rigid perceptual attitude. Consequently, perceptual discontinuity experienced during momentary immersion into a VE would be expected to increase symptoms of dissociation among individuals prone to develop them. It has been put forward that a tendency toward immersion or absorption, linking to imaginative processes underlying the dissociative experience, significantly relates to the level of change in virtual reality-induced dissociative symptoms. Consequently, it has been implied that increased tolerability of perceptual discontinuities and a more flexible perceptual attitude in people suffering depersonalization/derealization disorder may be of help. We propose the use of adaptive immersive virtual environments to the treatment of depersonalization. In particular, we propose that implementation of biofeedback electrical stimulation to detect somato-sensory processing bias may contribute to selectively targeting deranged neurocognitive processing components, and as an indirect consequence promote, to some extent, the diagnostic process. Psychophysiological approaches may be of help in the treatment of depersonalization via additional series of afferent inputs - virtual reality (VR) stimuli - to alter the receptive fields of the affected proprioceptive systems and reorganize them. The aim of this paper is to stimulate future research towards the development of potential virtual rehabilitation programs based on biofeedback, electrical stimulation and concurrent measurement of galvanic skin response and EEG targeting selective somatosensory stimulation in patients with depersonalization. Our research hypotheses might constitute a starting point for the development of new treatment tools for depersonalization in particular and depersonalization/derealization disorder in general.

Abstract
Dementia is a debilitating impairment of cognitive functions that affects millions of people worldwide. There are several diseases belonging to the dementia spectrum, most prominently Alzheimer’s disease (AD), vascular dementia (VD), Lewy body dementia (LBD) and frontotemporal dementia (FTD). Repetitive transcranial magnetic stimulation (rTMS) is a safe, non-invasive form of brain stimulation that utilizes a magnetic coil to generate an electrical field and induce numerous changes in the brain. It is considered efficacious for the treatment of various neuropsychiatric disorders. In this paper, we review the available studies involving rTMS in the treatment of these dementia types. The majority of studies have involved AD and shown beneficial effects, either as a standalone, or as an add-on to standard-of-care pharmacological treatment and cognitive training. The dorsolateral prefrontal cortex seems to hold a central position in the applied protocols, but several parameters still need to be defined. In addition, rTMS has shown potential in mild cognitive impairment as well. Regarding the remaining dementias, research is still at preliminary phases, and large, randomized studies are currently lacking.

Abstract
Melodic intonation therapy (MIT) is one of the most well-known treatment methods which is based on pitch and rhythm and was developed to increase verbal output in adults with non-fluent aphasia. Although MIT has been adapted to several languages, in Greece it is almost unknown. The aim of the proposed study is twofold: (1) to translate and adapt the MIT to the Greek language, and (2) to conduct an experimental study in order to examine the effect of MIT on Greek patients with Broca’s aphasia. To this aim, a 64-year-old, right-handed male who had a 6-year primary school education level, no musical abilities and poor performance on the recognition of prosody attended the MIT intervention program almost two and a half years after the event of suffering an ischemic stroke. The MIT intervention was administered three times per week for a 12-week period, in which each session lasted from 30 to 40 min. The patient underwent three assessments all using both the Boston Diagnostic Aphasia Examination–Short Form (BDAE-SF) and brain perfusion single-photon emission computed tomography (SPECT); (1) before the MIT, (2) immediately after, and (3) 3 months after the completion of MIT. The results from the BDAE-SF revealed an impressive improvement on both trained and prepositional speech production, immediately after the completion of the MIT, and a stable improved performance 3 months after MIT. The SPECT scan revealed reactivation of the perilesional areas of the left hemisphere, and considerably improved perfusion of the frontal lobe, the anterior temporal lobe, and the upper part of the parietal lobe of the right hemisphere. The improvement persisted and even expanded 3 months after MIT. Therefore, MIT is a promising intervention program and its positive effects last for at least 3 months after the completion of the intervention.

Abstract
OBJECTIVE The present study reviewed published evidence on the effectiveness of non-invasive brain stimulation (NIBS) on the cognitive performance of patients with Traumatic brain injury (TBI). METHOD A systematic search of the PubMed and Google Scholar databases was carried out. Randomized Controlled Studies published before March 2020 were included. Methodological evaluation was performed based on the Risk of Bias Cochrane tool. A total of 10 placebo-controlled studies fulfilled the inclusion criteria and were involved in the qualitative analysis, two assessing NIBS combined with cognitive training (CT) and eight evaluating NIBS alone. RESULTS All but one retrieved article were appraised as of high-risk of bias (one paper was assessed as of unclear-risk owing to considerable underreporting). With the potential exception of attention, our findings were not indicative of a superior efficacy of NIBS-CT to CT alone, regarding the improvement of any of the rest assessed cognitive deficits. Executive function, processing speed, attention, working, and visuospatial memory were only occasionally found to benefit from NIBS alone compared to sham therapy (only one study reported relevant benefits per neuropsychological outcome). Verbal memory and verbal fluency (phonemic-semantic) were consistently found not to benefit from NIBS. Depression measures were the only outcomes associated with a beneficial effect of NIBS in more than one article. CONCLUSION Our findings did not provide sufficient high-quality evidence to support the exclusive use of NIBS or combined NIBS-CT to improve any impaired cognitive function in TBI patients. Owing to the suboptimum methodological quality of published studies, additional research is of potential value.

Abstract
INTRODUCTION Short cognitive screening instruments (CSIs) are widely used to stratify patients presenting with cognitive symptoms. The Quick Mild Cognitive Impairment (Qmci) screen is a new, brief (<5mins) CSI designed to identify mild cognitive impairment (MCI), which can be used across the spectrum of cognitive decline. Here we present the translation of the Qmci into Greek (Qmci-Gr) and its validation against the widely-used Standardised Mini-Mental State Examination (SMMSE). METHODS Consecutive patients aged ≥55 years presenting with cognitive complaints were recruited from two outpatient clinics in Greece. All patients completed the Qmci-Gr and SMMSE and underwent an independent detailed neuropsychological assessment to determine a diagnostic classification. RESULTS In total, 140 patients, median age 75 years, were included; 30 with mild dementia (median SMMSE 23/30), 76 with MCI and 34 with subjective memory complaints (SMC) but normal cognition. The Qmci-Gr had similar accuracy in differentiating SMC from cognitive impairment (MCI & mild dementia) compared with SMMSE, area under the curve (AUC) of 0.84 versus 0.79, respectively; while accuracy was higher for the Qmci-Gr, this finding was not significantly different, (p = .19). Similarly, the Qmci-Gr had similar accuracy in separating SMC from MCI, AUC of 0.79 versus 0.73 (p = .23). CONCLUSIONS The Qmci-Gr compared favorably with the SMMSE. Further research with larger samples and comparison with other instruments such as the Montreal Cognitive Assessment is needed to confirm these findings but given its established brevity, it may be a better choice in busy clinical practice in Greece.

Abstract
Amyotrophic lateral sclerosis (ALS) is a multifactorial neurodegenerative disease. Inflammatory processes are among the mechanisms that are implicated in ALS pathogenesis. The TREM2 rs75932628 T variant may influence the regulatory effect of TREM2 on inflammation. Studies regarding the role of the rs75932628 variant in ALS have yielded inconsistent results, so far. To assess the role of TREM2 rs75932628 on ALS risk. We genotyped 155 patients with sporadic ALS and 155 healthy controls for TREM2 rs75932628. We also merged and meta-analyzed our data with data from previous studies (with a total of 7524 ALS cases and 14,675 controls), regarding TREM2 rs75932628 and ALS. No ALS or healthy subjects carried the TREM2 rs75932628-T variant. Results from meta-analyses (overall approach and sensitivity analyses) yielded no significant results for possible connection between TREM2 rs75932628-T variant and ALS. Based on our results, TREM2 rs75932628 does not seem to play a determining role to the pathophysiology of ALS.

Abstract
Multiple sclerosis (MS) is the most well-known autoimmune disorder of the central nervous system, and constitutes a major cause of disability, especially in young individuals. A wide array of pharmacological treatments is available, but they have often been proven to be ineffective in ameliorating disease symptomatology or slowing disease progress. As such, non-invasive and non-pharmacological techniques have been gaining more ground. Transcranial magnetic stimulation (TMS) utilizes the electric field generated by a magnetic coil to stimulate neurons and has been applied, usually paired with electroencephalography, to study the underlying pathophysiology of MS, and in repetitive trains, in the form of repetitive transcranial magnetic stimulation (rTMS), to induce long-lasting changes in neuronal circuits. In this review, we present the available literature on the application of TMS and rTMS in the context of MS, with an emphasis on its therapeutic potential on various clinical aspects, while also naming the ongoing trials, whose results are anticipated in the future.

Abstract
Here we present a case of a native Greek male patient who presented clinically with sudden onset pure word deafness after an ischemic stroke in the temporoparietal region of the right hemisphere, but who had suffered an ischemic stroke 9 years previously in an adjacent area of the left hemisphere, causing aphasic symptoms which resolved quickly and almost completely. What makes this case interesting and novel is that it is the first case describing a patient whose ventral language comprehension circuit did not reorganize successfully due to damage of the adjacent right hemisphere language areas at a subsequent time.

Abstract
OBJECTIVES The purpose of this study was to generate normative data on the Symbol Digits Modalities Test (SDMT) for the written and oral versions in the Greek adult population. We also investigated the test's validity in discriminating the performance of healthy adults from two groups of adults diagnosed with relapsing remitting (RRMS) and secondary progressive (SPMS) multiple sclerosis. METHOD The sample consisted of 609 healthy men and women between the ages of 18 and 65. All participants were monolingual native Greek adult speakers. Each healthy participant was administered either the written (n = 460) or oral (n = 149) versions of the SDMT. Discriminant validity was examined by comparing 35 healthy participants who had completed the oral version of the SDMT to 35 age - and education-matched RRMS and SPMS patients. RESULTS Linear regression models explained between 36% and 55% of the variance in the SDMT oral and written version scores. Age was the strongest predictor of difference in SDMT written and oral version performance, followed by education that also accounted for a further proportion of the SDMT variance. On the contrary, gender was found not to contribute significantly to the variance in the SDMT for either the written or the oral versions. As a result, age- and education-adjusted norms were generated. Regarding the tests discriminative validity, we found that both MS patient groups scored significantly lower than the healthy group. CONCLUSIONS This is the first study to provide comprehensive normative data for the SDMT in the adult population in Greece, impacting the future practice of neuropsychological assessment in this country.

Abstract
Background A recent systematic review found that language deficits are not very common in individuals with multiple sclerosis (MS). However, there are significant gaps in our knowledge about language abilities in MS. For instance, morphosyntactic production has not been explored adequately thus far. This study investigated verb-related morphosyntactic production in MS focusing on Greek, a morphologically rich language. Methods A sentence completion task tapping into the production of subject-verb agreement, time reference/tense, and grammatical aspect was administered to 39 Greek-speaking individuals with MS [25 individuals with relapsing-remitting MS (RRMS group) and 14 individuals with secondary progressive MS (SPMS group)]. The task included only regular verbs. Generalized linear mixed-effects models were used to investigate the ability of individuals with MS to produce the above-mentioned morphosyntactic categories. Results Overall, the RRMS and SPMS groups performed significantly worse than their matched control groups. Moreover, all four groups performed significantly worse on grammatical aspect than on subject-verb agreement and time reference. The difference between subject-verb agreement and time reference was not significant in any of the four groups. The overall performances of the RRMS and SPMS groups did not differ significantly. Conclusion Individuals with MS are impaired in verb-related morphosyntactic production. Moreover, the pattern of performance of individuals with MS is identical to that exhibited by neurologically healthy individuals. Thus, the production performance of individuals with MS on verb inflection differs from that of healthy controls quantitatively but not qualitatively.

Abstract
In this explorative study, forty-seven patients with relapsing-remitting multiple sclerosis were randomized to a custom 6-week cognitive rehabilitation intervention (n = 23) using the BrainHQTM web-based platform and to a control group condition (n = 24). Cognitive rehabilitation intervention consisted of two 40-minute sessions per week. All patients were tested with the Brief International Cognitive Assessment for Multiple Sclerosis battery, the Stroop Color-Word Test, and the trail making test, while the Beck Depression Inventory - Fast Screen questionnaire was used as a measure of mood and the cognitive reserve index as a measure of cognitive reserve. We used the reliable change index, to calculate clinically meaningful changes of performance, and to discriminate between responders and non-responders of this intervention. Statistically significant improvement of the group receiving treatment was observed mainly on measures of verbal and non-verbal episodic memory and, to a lesser extent, on reading speed, selective attention/response inhibition, and visual attention. Verbal memory and visual attention improvements remained significant after considering the corrected for multiple comparisons level of significance. According to reliable change index scores, 12/23 (52.2%) of patients in the intervention group presented meaningful improvement in at least one measure (Greek Verbal Learning Test: 26%, Brief Visuospatial Memory Test-Revised: 17.4%, Stroop-Words test: 13%). This explorative study provides evidence that, at least in the short term, cognitive rehabilitation may improve the cognitive performance of multiple sclerosis patients.

Abstract
OBJECTIVES Cognitive impairment is common in multiple sclerosis, but the brain MRI correlates in relapsing remitting multiple sclerosis remain controversial. The current study aimed to investigate whether cognitive decline can be predicted by global and/or regional brain atrophy. METHODS Sixty-three patients with relapsing remitting multiple sclerosis (36 men, mean age 39.9 ± 9.4 years old, mean EDSS 1.4 ± 1.2, mean disease duration 4.9 ± 4.3 years) and 46 healthy controls (21 men, mean age 37.5 ± 10.8 years old) were included. Demographic data were obtained, and a longitudinal neuropsychological and global and regional MRI brain volume assessment was performed. RESULTS The patients performed worse than controls in most neuropsychological tests at baseline. The percentage of patients with clinically meaningful cognitive decline ranged from only 0% to 7.9%. Statistically significant volume reduction was found for all MRI measures except for the left accumbens nucleus. Whole or regional brain atrophy ranged from -0.02% to -0.25%, with subcortical structures showing the largest atrophy rates. A total of 22.2% to 93.7% patients showed atrophy across the brain structures assessed volumetrically. DISCUSSION It was regional rather than whole-brain changes that significantly predicted cognitive decline for the patients in the tasks that tested processing speed, visuo-spatial and inhibition skills. The overall data suggest that the progression of cognitive impairment in relapsing remitting multiple sclerosis as captured by conventional neuropsychological testing is the tip of the iceberg of neurodegenerative sequelae in the disease. Also, regional volumetric changes are better than whole-brain atrophy at predicting cognitive dysfunction.

Abstract
Multiple sclerosis (MS) is a chronic, immune-mediated, inflammatory, and degenerative disease of the central nervous system (CNS) that affects both white and gray matter. Various mechanisms throughout its course, mainly regarding gray matter lesions and brain atrophy, result in cognitive network dysfunction and can cause clinically significant cognitive impairment in roughly half the persons living with MS. Altered cognition is responsible for many negative aspects of patients' lives, independently of physical disability, such as higher unemployment and divorce rates, reduced social activities, and an overall decrease in quality of life. Despite its devastating impact it is not included in clinical ratings and decision making in the way it should be. It is interesting that only half the persons with MS exhibit cognitive dysfunction, as this implies that the other half remain cognitively intact. It appears that a dynamic balance between brain destruction and brain reorganization is taking place. This balance acts in favor of keeping brain systems functioning effectively, but this is not so in all cases, and the effect does not last forever. When these systems collapse, functional brain reorganization is not effective anymore, and clinically apparent impairments are evident. It is therefore important to reveal which factors could make provision for the subpopulation of patients in whom cognitive impairment occurs. Even if we manage to detect this subpopulation earlier, effective pharmaceutical treatments will still be lacking. Nevertheless, recent evidence shows that cognitive rehabilitation and neuromodulation, using non-invasive techniques such as transcranial magnetic or direct current stimulation, could be effective in cognitively impaired patients with MS. In this Mini Review, we discuss the mechanisms underlying cognitive impairment in MS. We also focus on mechanisms of reorganization of cognitive networks, which occur throughout the disease course. Finally, we review theoretical and practical issues of neurorehabilitation and neuromodulation for cognition in MS as well as factors that influence them and prevent them from being widely applied in clinical settings.

Abstract
Abstract
Background
Cognitive dysfunction is one of the most prevalent non-motor aspects of Parkinson’s disease (PD). The present review focuses on published studies investigating the effect of computer-based cognitive training (CT) on neuropsychological performance in PD.
Methods
A systematic search of the PubMed database and Google Scholar was carried out. Randomized controlled studies published before September 2019, investigating the effect of computer-based CT (regardless of the comparator, active or placebo) on PD patients were included. Literature search, data extraction, and Risk of Bias (RoB) evaluation (based on the RoB Cochrane tool for Randomized Trials) were performed by two authors (A.N. and M.M), independently.
Results
Among 30 full-texts assessed for eligibility, seven articles fulfilled the inclusion criteria and were involved in the qualitative analysis. The main outcomes of the retrieved studies (all studies used similar cognitive rehabilitation methodologies) were indicative of cognitive improvement in most cognitive domains, particularly memory, executive function, processing speed, and attention, that is, the domains primarily impaired in the disease.
Conclusion
Multidomain CT, which is exclusively based on computer software, leads to measurable improvements in most cognitive domains affected in patients with PD. The present review is the first to include studies assessing the effect of computer-based CT techniques without deploying CT with paper-pencil techniques. Limitations originate mainly due to the heterogeneity among included studies (differences in CT softwares, PD stages, number, and duration of training sessions.

Abstract
BACKGROUND Cognitive impairment is common in multiple sclerosis (MS), but deficits tend to be more pronounced in progressive MS, negatively impacting daily functional capacity. Despite this, most cognitive rehabilitation (CR) interventions to date have focused on relapsing-remitting MS (RRMS). Moreover, information on the efficacy of CR in progressive MS is limited and controversial. The present study investigated the efficacy of a home based, computer assisted cognitive rehabilitation (HBCACR) intervention (RehaComTM software) exclusively in a Secondary Progressive Multiple Sclerosis (SPMS) sample. METHODS This was a randomized, multi site, sham controlled trial. Thirty six (36) individuals with SPMS, naïve to the RehaCom software, with cognitive deficits were randomized to the treatment (IG; n= 19) or control group condition (CG; n=17). Treatment with the RehaCom modules consisted of 24 domain and task specific, 45 minute session's over an 8-week period, three sessions per week, applied by each patient at home. The CG completed non specific computer based activities at home with the same frequency and duration. Primary cognitive outcome measures included the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) battery, and secondary outcome measures for depression (BDI-FS), fatigue (MFIS), and quality of life (EuroQol EQ-5D) visual analogue scale (VAS). RESULTS The two groups were well matched on demographic and clinical characteristics, cognitive reserve and severity of cognitive deficits at baseline assessment. At post treatment assessment the IG group showed significant improvements with large effect sizes; in verbal learning [z = -4.759, p <.0005, g = 2.898], visuospatial memory [z = -3.940, p <.0005, g = 1.699] and information processing speed [z= -4.792, p <.0005, g = 2.980], compared with the sham control group. We also found significant between group differences on physical [z=-3.308, p = .001, g= -.604], cognitive [z = -4.011, p <.0005, g = -1.654], psychosocial [z= 3.308, p = .010, g = -.940], and general fatigue impact [z= -2.623, p = .008, g = -.519], depression severity [z = -2.730, p = .006, g = -.519], and quality of life [z= -4.239, p <.0005, g = -1.885] in favor of the treated group. CONCLUSION These data provide the first evidence supporting the efficacy of computer based restorative cognitive rehabilitation applied at home exclusively in SPMS patients, suggesting that adaptive neuroplasticity may occur after functional cognitive training in progressive MS. Improved cognitive functioning in combination with mood augmentation appear to have ameliorated fatigue, which impacted daily functioning activity and culminated in improved health related quality of life.

Abstract
BACKGROUND There is still a strong need for an optimal clinician-friendly screening tool for the identification of aspiration risk in stroke patients. In this study, we present the development of a novel, context-specific screening tool for the prediction of aspiration risk on recent stroke survivors, the Functional Bedside Aspiration Screen (FBAS), and examine its construct validity, reliability with the predictive values toward pragmatic patients' outcomes. METHODS We conducted a prospective validation study of 104 acute ischemic stroke patients admitted to clinical wards in a tertiary university hospital. A group of experts developed and administered the FBAS 10-point scale to all patients. Outcome measures were compared with those of the validated Yale Swallow Protocol (YSP, reference measure) and health indicators. KEY RESULTS A strong association was found between the FBAS cutoff criterion and the YSP (Pearson χ2 = 54.92, P < .001). A score of ≤8 on the FBAS presented with 93.3% sensitivity and 83.3% specificity in deeming patient with reduced safety for oral nutrition (AUC = 0.934, CI = 0.884-0.985). An inverse relationship was found between performance on the FBAS and in-hospital and long-term outcome indicators. Patients who failed the FBAS were 1.82 times more likely to develop aspiration pneumonia (95% CI = 1.42-2.35) and 1.35 times more likely to develop pneumonia within 3 months postonset (95% CI = 1.15-1.59). CONCLUSIONS AND INFERENCES The FBAS is a potentially useful tool for timely prediction of aspiration risk and health outcome in acute stroke.

Abstract
Objective:
Given the underlying frontal-basal ganglia circuit neuropathogenesis of HIV-infected individuals, it is surprising that little is reported about potential language deficits as part of their higher cognitive dysfunctional profile. This study aims to elucidate whether HIV-positive individuals have linguistic impairments that may originate from or be intensified by deficits in cognitive functions. The research questions address (i) quantitative differences in sentence repetition abilities involving complex syntactic phenomena between adults with HIV and non-HIV healthy controls (ii) correlations of sentence repetition scores with neurocognitive measures and (iii) correlation of sentence repetition performance with duration and severity of HIV.
Methods:
A battery of neuropsychological tests were administered to 40 HIV - seropositive males and 40 demographically matched healthy controls to assess verbal learning/episodic memory, psychomotor speed, executive functions and visuospatial abilities. Language abilities were evaluated using a repetition task that screened specific complex syntactic operations at the sentence-level.
Results:
A significant difference was noted between the two groups regarding correct repetition of the sentence repetition task with the control group outperforming the HIV-seropositive group. For the HIV group, significant correlations were found for correct sentence repetition with years of education, duration of illness, Mini-Mental State Examination, semantic and phonemic fluency, symbol digit modality test scores, and the Trail Making Test (parts A and B).
Conclusion:
Speech-language pathologists and neuropsychologists should screen for language deficits associated with the different clinical syndromes in HIV patients as part of their routine clinical care.

Abstract
Cognitive decline has been widely reported in patients with multiple sclerosis (MS) despite its clinical heterogeneity, at all stages and in all subtypes of the disease. Deficits are most commonly present in attention, processing speed, working memory, verbal fluency and executive function. However, MS patients also show decreased performance in tasks related to social cognition, i.e. mental operations thatdrive interpersonal skills such as social perception, empathy and theory of mind. Social cognitive deficits are an underestimated but important aspect of impairment in MS, reflecting how people process, store, and apply information in social interactions. Deficits in these domains have been associated with reduced social and psychological quality of life, even after controlling for severity and duration of the disease, age, and neurocognitive performance. Social cognition impairment is not entirely dependent on and parallel to general cognitive dysfunction, given that some patients experience disorganization of their social life before a significant or detectable cognitive impairment. The decrease in performance of social cognition tasks may reflect changes in brain activity and brain structure, either general or regional. Both subtle diffuse pathology and acute local lesions have at least partially independent effects on aspects of social cognition. The observed white matter damage contributes to a mechanism of disruption in the network of brain connections involved in social cognition. Undoubtedly, there is a wide variability in the relationship of social cognitionand neuroanatomical findings, not only due to the brain's complex connectivity, but also to the lack of a unique operative definition of these cognitive domains. Furthermore, it is difficult to compare study results, given the variability of clinical presentations in all stages of the disease.More research would contribute in understanding social cognition deficits better and in determining whether and what kind of training could be beneficial.

Abstract
OBJECTIVES Cognitive impairment is present in up to 65% of Relapsing Remitting Multiple sclerosis (RRMS) patients and can be extremely debilitating. Although deficits in episodic memory and processing speed occur more frequently than executive deficits, executive dysfunction tends to have a significant impact on MS patients' ability to generate strategies, think divergently, solve and estimate problems, and reason in abstract terms with substantial negative impacts on activities of daily living. In the present study we investigated perfusion detection rate and pattern, as well as the association between perfusion rates and cognitive dysfunction in cognitively impaired RRMS patients. METHODS We present findings from 17 cognitively impaired RRMS patients who were evaluated with a comprehensive neuropsychological battery and additionally evaluated by brain perfusion radiopharmaceutical technetium-99m hexamethyl-propylene amine oxime (99mTc HMPAO). RESULTS RRMS patients had hypoperfusion in several predefined Brodmann areas and lobes of the brain, relatively to demographically matched healthy controls according to an established normative database NeuroGam™. However, we noted blood flow reduction, mainly in the frontal lobes and other related prefrontal areas, involving both hemispheres, but with asymmetric left hemisphere predominance. Moreover, associations between measures of response inhibition, set shifting (executive functions) and severity of hypoperfusion in the left frontal lobes were also established. CONCLUSION Cerebral hypoperfusion is an integral feature of MS pathology. Executive dysfunction is associated with robust cerebral perfusion deficits in the frontal and prefrontal cortex of cognitively impaired RRMS patients.

Abstract
Background and Purpose There is an increasing interest in the effect of nonpharmacological interventions on the course of patients with Alzheimer's disease (AD). The objective of the present study is to determine the benefits of a structured, multidomain, mostly computer-based, cognitive training (MCT) οn the cognitive performance of patients with early-stage AD. Method Fifty patients with early-stage AD participated in the study. Patients were randomly allocated either to the training program group (n = 25) or to a wait list control group (n = 25). The training program group received computer-assisted MCT and linguistic exercises utilizing pen and paper supplemented by cognitive-linguistic exercises for homework. The duration of the MCT intervention program was 15 weeks, and it was administered twice a week. Each session lasted for approximately one hour. Objective measures of episodic memory, delayed memory, word recognition, attention, executive function, processing speed, semantic fluency, and naming were assessed at baseline and after the completion of the program in both groups. Results Analysis showed that in controls, delayed memory and executive function had deteriorated over the observation period of 15 weeks, while the training group improved their performance in word recognition, Boston Naming Test (BNT), semantic fluency (SF), clock-drawing test (CDT), digit span forward (DSF), digit span backward (DSB), trail-making test A (TMT A), and trail-making test B (TMT B). Comparison between the training group and the controls showed that MCT had a significant beneficial effect in delayed memory, naming, semantic fluency, visuospatial ability, executive functions, attention, and processing speed. Conclusions The study provides evidence of a beneficial effect of MCT with an emphasis on cognitive-language performance of patients with early-stage AD. Considering the limited efficacy of current pharmacological therapies in AD, concurrent computer-based MCT may represent an additional enhancing treatment option in early-stage AD patients.

Abstract
BACKGROUND AND PURPOSE The presence of dysphagia and aspiration in stroke patients is associated with increased mortality and morbidity. Early recognition and management of these two conditions via reliable, minimally invasive bedside procedures before complications arise remains challenging in everyday clinical practice. This study reviews the available bedside screening tools for detecting swallowing status and aspiration risk in acute stroke by qualitatively observing reference population study design, clinical flexibility, reliability and applicability to acute-care settings. METHODS The primary search was conducted using the PubMed, Embase, and Cochrane Library databases. The search was limited to papers on humans written in English and published from 1991 to 2016. Eligibility criteria included the consecutive enrollment of acute-stroke inpatients and the development of a protocol for screening aspiration risk during oral feeding in this population. RESULTS Of the 652 sources identified, 75 articles were reviewed in full however, only 12 fulfilled the selection criteria. Notable deficiencies in most of the bedside screening protocols included poor methodological designs and inadequate predictive values for aspiration risk which render clinicians to be more conservative in making dietary recommendations. CONCLUSIONS The literature is dense with screening methods for assessing the presence of dysphagia but with low predictive value for aspiration risk after acute stroke. A standard, practical, and cost-effective screening tool that can be applied at the bedside and interpreted by a wide range of hospital personnel remains to be developed. This need is highlighted in settings where neither trained personnel in evaluating dysphagia nor clinical instrumentation procedures are available.

Abstract
About half of patients with multiple sclerosis exhibit cognitive impairment which negatively affects their quality of life. The assessment of cognitive function in routine clinical practice is still undervalued, although various tools have been proposed for this reason. In this article, we describe the potential benefits of implementing cognitive assessment tools in routine follow -ups of MS patients. Early detection of changes in cognitive performance may provide evidence of disease activity, could unmask depression or medication side-effects and provide suitable candidates for cognitive rehabilitation. Since apathy and cognitive deficiencies are common presenting symptoms in Progressive Multifocal Leukoencephalopathy, we discuss the utility of frequent monitoring of mental status in multiple sclerosis patients at increased risk. In addition, we propose a relevant algorithm aiming to incorporate a systematic evaluation of cognitive function in every day clinical practice in multiple sclerosis.

Abstract
Objective: The objective of this study was to investigate the pattern and severity of cognitive and language impairment in Greek patients with Relapsing-remitting (RRMS) and Secondary Progressive Multiple Sclerosis (SPMS), relative to control participants. Method: A prospective study was conducted in 27 patients with multiple sclerosis (PwMS), (N= 15) with RRMS, (N= 12) with SPMS, and (N= 12) healthy controls. All participants were assessed with a flexible comprehensive neuropsychological – language battery of tests that have been standardized in Greece and validated in Greek MS patients. They were also assessed on measures of disability (Expanded Disability Status Scale; EDSS), fatigue (Fatigue Severity Scale; FSS) and depression (Beck Depression Inventory - fast screen; BDI-FS). Results: Our results revealed that groups were well matched on baseline demographic and clinical characteristics. The two clinical groups (RRMS; SPMS) did not differ on overall global cognitive impairment but differed in the initial encoding of verbal material, mental processing speed, response inhibition and set-shifting. RRMS patients differed from controls in the initial encoding of verbal material, learning curve, delayed recall of verbal information, processing speed, and response inhibition. SPMS patients differed in all utilized measures compared to controls. Moreover, we noted increased impairment frequency on individualized measures in the progressive SPMS group. Conclusion: We conclude that MS patients, irrespective of clinical subtype, have cognitive deficits compared to healthy participants, which become increasingly worse when they convert from RRMS to SPMS.On the contrary,the pattern of impairment remains relatively stable.
