Neurocognitive Impairment in Long COVID: A Systematic Review.

OBJECTIVE: Although Coronavirus disease 2019 (COVID-19) is primarily a respiratory infectious disease, it has also been associated with a wide range of other clinical manifestations. It is widely accepted in the scientific community that many patients after recovery continue to experience COVID-19-related symptoms, including cognitive impairment. The aim of this systematic review was to investigate the cognitive profile of patients with long-COVID syndrome. METHODS: A systematic search of empirical studies was conducted through the PubMed/Medline and Scopus electronic databases. Cross-sectional and longitudinal studies published between 2020 and 2023 were included. RESULTS: Of the 516 studies assessed for eligibility, 36 studies met the inclusion criteria. All included studies support the presence of persistent cognitive changes after COVID-19 disease. Executive function, memory, attention, and processing speed appear to be the cognitive domains that are predominantly associated with long-COVID syndrome, whereas language is an area that has not been sufficiently investigated. CONCLUSIONS: In this review, the high frequency of cognitive impairment after COVID-19 is evident. If we consider that cognitive functioning affects our ability to live independently and is a key determinant of our quality of life, it is imperative to precisely define those factors that may induce cognitive impairment in COVID-19 survivors, with the ultimate goal of early diagnosis of cognitive changes and, consequently, the development of targeted rehabilitation interventions to address them.

Cognitive trajectories preluding the onset of different dementia entities: a descriptive longitudinal study using the NACC database.

OBJECTIVE: To describe the 10-year preclinical cognitive trajectories of older, non-demented individuals towards the onset of the four most prevalent types of dementia, i.e., Alzheimer's disease(AD), Lewy body(LBD), vascular(VD) and frontotemporal dementia(FTD). METHODS: Our analysis focused on data from older (≥ 60years) NACC (National Alzheimer's Coordinating Center) participants. Four distinct presymptomatic dementia groups (AD-LBD-VD-FTD) and a comparison group of cognitively unimpaired(CU) participants were formed. Comprehensive cognitive assessments involving verbal episodic memory, semantic verbal fluency, confrontation naming, mental processing speed - attention and executive function - cognitive flexibility were conducted at baseline and on an approximately yearly basis. Descriptive analyses (adjusted general linear models) were performed to determine and compare the yearly cognitive scores of each group throughout the follow-up. Exploratory analyses were conducted to estimate the rates of cognitive decline. RESULTS: There were 3343 participants who developed AD, 247 LBD, 108 FTD, 155 VD and 3398 composed the CU group. Participants with AD performed worse on episodic memory than those with VD and LBD for about 3 to 4 years prior to dementia onset (the FTD group documented an intermediate course). Presymptomatic verbal fluency and confrontation naming trajectories differentiated quite well between the FTD group and the remaining dementia entities. Participants with incident LBD and VD performed worse than those with AD on executive functions and mental processing speed-attention since about 5 years prior to the onset of dementia, and worse than those with FTD more proximally to the diagnosis of the disorder. CONCLUSIONS: Heterogeneous cognitive trajectories characterize the presymptomatic courses of the most prevalent dementia entities.

Neurocognitive Impairment and Social Cognition in Parkinson's Disease Patients.

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.

Language and Communication Interventions in People with Alzheimer's Disease: A Systematic Review.

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.

Adaptation and validation of the Greek version of the Communication and Language Assessment questionnaire for persons with Multiple Sclerosis (CLAMS).

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.

The Contribution of Functional Near-Infrared Spectroscopy (fNIRS) to the Study of Neurodegenerative Disorders: A Narrative Review.

Functional near-infrared spectroscopy (fNIRS) is an innovative neuroimaging method that offers several advantages over other commonly used modalities. This narrative review investigated the potential contribution of this method to the study of neurodegenerative disorders. Thirty-four studies involving patients with Alzheimer's disease (AD), mild cognitive impairment (MCI), frontotemporal dementia (FTD), Parkinson's disease (PD), or amyotrophic lateral sclerosis (ALS) and healthy controls were reviewed. Overall, it was revealed that the prefrontal cortex of individuals with MCI may engage compensatory mechanisms to support declining brain functions. A rightward shift was suggested to compensate for the loss of the left prefrontal capacity in the course of cognitive decline. In parallel, some studies reported the failure of compensatory mechanisms in MCI and early AD; this lack of appropriate hemodynamic responses may serve as an early biomarker of neurodegeneration. One article assessing FTD demonstrated a heterogeneous cortical activation pattern compared to AD, indicating that fNIRS may contribute to the challenging distinction of these conditions. Regarding PD, there was evidence that cognitive resources (especially executive function) were recruited to compensate for locomotor impairments. As for ALS, fNIRS data support the involvement of extra-motor networks in ALS, even in the absence of measurable cognitive impairment.

Adaptation and validation of the Greek version of the Speech Pathology-Specific Questionnaire for Persons with Multiple Sclerosis (SMS).

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.

Face-to-face vs. Telerehabilitation language and cognitive training in patients with multi-domain amnestic mild cognitive impairment.

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.

Illiteracy, Neuropsychological Assessment, and Cognitive Rehabilitation: A Narrative Review.

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.

Noninvasive Brain Stimulation in Primary Progressive Aphasia: A Literature Review.

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.

Repetitive Transcranial Magnetic Stimulation in Post-stroke Aphasia: Comparative Evaluation of Inhibitory and Excitatory Therapeutic Protocols: Narrative Review.

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.

Lack of Association between CD33 rs3865444 and Amyotrophic Lateral Sclerosis: A Case-Control Study.

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.

Cognitive Rehabilitation for Patients with Schizophrenia: A Narrative Review of Moderating Factors, Strategies, and Outcomes.

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.

Cognitive Neurorehabilitation in Epilepsy Patients via Virtual Reality Environments: Systematic Review.

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.

Epilepsy and the "dark" literature of the Greek novelist Demosthenes Voutyras: an outstanding epileptic personality / Epilepsia e a literatura "sombria" do romancista grego Demosthenes Voutyras: uma personalidade epilética notável

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.

Resumo Antecedentes O papel da epilepsia do lobo temporal (ELT) na determinação de traços de personalidade e sintomas neurocomportamentais, coletivamente conhecidos como síndrome comportamental interictal (também conhecida como síndrome de Geschwind ou "síndrome de Gastaut-Geschwind"), bem como a associação da síndrome com o expressão de muitos literatos epilépticos são bem conhecidos em neurologia e psiquiatria. Um aprofundamento da emotividade juntamente com um comportamento sério, altamente ético e espiritual tem sido descrito como mudanças positivas de personalidade em pacientes com ELT mesial crônica. Objetivos A nossa hipótese clínica narrativa visa contribuir para o debate em curso sobre a associação entre ELT e a expressão artística, bem como a suposta implicação desta última para a epilepsia em geral e a neuropsicologia da epilepsia em particular. Métodos Através de uma análise da biografia, linguagem e obra literária do romancista grego Demóstenes Voutyras, levantamos a hipótese de que seu estilo de escrita místico e sombrio poderia ser atribuído à dinâmica interictal temporal medial. Conclusões Sugerimos que o perfil psicoliterário de Voutyras é consistente com as características idiossincráticas da personalidade do lobo temporal, enquanto uma contribuição do lobo temporal não dominante foi proposta.

Undetected language deficits in left or right hemisphere post-stroke patients.

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.

Computer-Based Cognitive Training vs. Paper-and-Pencil Training for Language and Cognitive Deficits in Greek Patients with Mild Alzheimer's Disease: A Preliminary Study.

The purpose of the present study was to explore whether Computer-Based Cognitive Training (C-BCT) versus Paper-Pencil Cognitive Training (P-PCT) is more beneficial in improving cognitive and language deficits in Greek patients living with Alzheimer's disease (pwAD). Twenty pwAD were assigned to two groups: (a) the C-BCT group, receiving a computer-based cognitive training program using the RehaCom software, and (b) the P-PCT group, which received cognitive training using paper and pencil. The cognitive training programs lasted 15 weeks and were administered twice a week for approximately one hour per session. The analyses of each group's baseline versus endpoint performance demonstrated that the P-PCT group improved on delayed memory, verbal fluency, attention, processing speed, executive function, general cognitive ability, and activities of daily living. In contrast, the C-BCT group improved on memory (delayed and working), naming, and processing speed. Comparisons between the two groups (C-BCT vs. P-PCT) revealed that both methods had significant effects on patients' cognition, with the P-PCT method transferring the primary cognitive benefits to real-life activities. Our findings indicate that both methods are beneficial in attenuating cognitive and language deficits in pwAD. The need for large-scale neurobehavioral interventions to further clarify this issue, however, remains a priority.
