Early diagnosis of MCI can guide timely treatment and delay dementia onset. The Montreal Cognitive Assessment (MoCA) is an effective screening tool for MCI. Remotely administered versions of the MoCA have gained popularity during the recent pandemic.Objective: This study aimed to validate a new Hindi version of the Telephone MoCA (T-MoCA) in older adult outpatients at a tertiary hospital in Delhi, India.Methods: We developed and validated a Hindi version of the T-MoCA (T-MoCA-Hindi) using the previously validated MoCA-Hindi as the gold standard. We administered both instruments to older adult patients with a 2-week gap between sessions. To assess the reliability of the new T-MoCA-Hindi, we used the Bland-Altman plot and Cronbach alpha. We used a receiver operating characteristic curve to estimate accuracy.Results: A total of 243 individuals enrolled in this study. The T-MoCA-Hindi and the MoCA-Hindi showed a high level of agreement. A Cronbach alpha of 0.84 indicated good internal consistency. The area under the curve in the receiver operating characteristic analysis was 93.5%, indicating excellent accuracy and validity and demonstrating high sensitivity and specificity at an optimal cut-off score of 18/19 points.Conclusion: These findings show that the T-MoCA-Hindi is a valid tool for remote identification of MCI in India. The use of remote versions of diagnostic tools can be leveraged to conduct research when in-person approaches may not be feasible.","PeriodicalId":50671,"journal":{"name":"Cognitive and Behavioral Neurology","volume":" ","pages":"35-42"},"PeriodicalIF":1.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143702017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the diagnostic utility of NeuroQuant HVs and HOCs within an academic memory disorders clinic.Methods: Participants ( n = 181) underwent neurologic examination, MRI with NeuroQuant, and neuropsychological assessment. Clinical diagnoses included subjective cognitive concerns ( n = 39), non-amnestic MCI ( n = 33), amnestic MCI ( n = 74), AD ( n = 35). Objective memory impairment ( n = 125) was determined using actuarial criteria (≥2 memory measures ≤1.5 SD below the mean) for each participant. Differences in HVs and HOCs were assessed using ANOVA and χ 2 , while Pearson correlations examined their relationship with the California Verbal Learning Test-2nd Edition (CVLT-II). Receiver operator characteristic curves were used to calculate sensitivity, specificity, predictive values, Youden's Index, and predictive summary index scores.Results: Participants with amnestic MCI, AD, and objective memory impairment had lower HVs and HOCs and a higher frequency of hippocampal atrophy (≤5th percentile) than participants with subjective cognitive concerns, non-amnestic MCI, and no objective memory impairment ( P' s <0.05). However, the sensitivity (0.31-0.77) and specificity (0.68-0.91) of HVs and HOCs were variable for determining objective memory impairment, and correlations with the CVLT-II were modest ( r = 0.20-0.44).Discussion: NeuroQuant HVs and HOCs were lower in participants with amnestic MCI, AD, and memory impairment, but had poor sensitivity and specificity to predict memory impairment, and only a modest association with measurable memory impairment. These measures should be used cautiously as supporting diagnostic tools.","PeriodicalId":50671,"journal":{"name":"Cognitive and Behavioral Neurology","volume":" ","pages":"43-49"},"PeriodicalIF":1.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144031209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We categorized each noun by attributes such as familiarity, smell, pain, taste, sound, graspability, and motion. We focused primarily on changes in the N400 component, indicative of semantic processing, across nouns with different attributes.Results: The least familiar stimuli elicited the strongest N400 response, indicating significant ERP variability across familiarity levels with more positive amplitudes for highly familiar stimuli. Among the attributes examined, only the attribute of smell demonstrated a notable, though isolated, increase in N400 amplitude. Other attributes, including pain, taste, sound, graspability, and visual motion showed no significant differences in N400 responses, suggesting a minimal influence on semantic processing in this context.Conclusion: These results suggest that the specific sensory attributes of objects have limited influence on the N400 component of ERPs in implicit reading tasks, highlighting the complexity of semantic networks in cognitive processing. The subtlety of ERP modulations driven by object-related attributes points to the need for further exploration into how these attributes interact within semantic networks during cognitive tasks.","PeriodicalId":50671,"journal":{"name":"Cognitive and Behavioral Neurology","volume":" ","pages":"50-59"},"PeriodicalIF":1.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144051196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initial misdiagnosis is common, as demonstrated by this case involving a 52-year-old female who presented with symptoms of limb numbness and weakness. Differential diagnosis first indicated Parkinsonism, lacunar infarction, and cervical spondylosis. Subsequently, however, this patient's clinical presentation evolved to include bradykinesia, cognitive decline, and a spectrum of neurological manifestations. A Pan-V2 assay revealed a heterozygous mutation in the CSF1R gene. Craniocerebral MRI showed cerebral infarctions, lacunar infarctions, and leukoaraiosis. Despite symptomatic treatments, our patient's clinical status continued to decline until her family chose to discontinue further medical interventions. This case underscores the diagnostic complexities of early detection of CSF1R-related disorders. It emphasizes the importance of including leukodystrophy in such differential diagnoses and the need for prompt genetic screening in patients who present with progressive leukoencephalopathy, especially when cerebrospinal fluid analysis is unremarkable.","PeriodicalId":50671,"journal":{"name":"Cognitive and Behavioral Neurology","volume":" ","pages":"16-20"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142958450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although their common-name anomia, alexia with agraphia, and semantic memory impairment resolved within 2 years, this individual continued to experience proper-name anomia and verbal memory impairment. Encephalitic damage was limited to the left anterior temporal lobe (ATL), amygdala, hippocampus, and parahippocampal gyrus, sparing the mid-fusiform and posterior inferior temporal gyri. Although ATL lesions are not typically associated with semantic memory impairment, we suggest that damage to the left ATL can result in both proper- and common-name anomia, as was evident in the current case. In these cases, proper-name anomia may be more severe and persistent than common-name anomia, which may be mild and significantly improved within several years. In cases of semantic memory deficits, persistent common-name anomia, and severe alexia with agraphia, there is typically more extensive involvement of the temporal lobe than seen in the current case, including the mid-fusiform and posterior inferior temporal gyri.","PeriodicalId":50671,"journal":{"name":"Cognitive and Behavioral Neurology","volume":" ","pages":"21-32"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
