Cognitive impairment in patients with brain tumors may result from focal neurological symptoms, increased intracranial pressure, or involvement of critical regions such as the prefrontal cortex and limbic system. Bilateral or midline lesions, including medial frontal gliomas, meningiomas, or suprasellar tumors affecting limbic circuits, often produce more prominent cognitive symptoms than unilateral lesions. Awake surgery has become a key technique for preserving higher cognitive functions by enabling intraoperative mapping of cortical and subcortical networks, particularly in lower-grade gliomas with potential for neuroplasticity. However, when preoperative deficits are already severe or bilateral damage is present, postoperative cognitive impairment may persist and affect daily functioning. In this report, we discuss the clinical manifestations of tumor-related cognitive dysfunction, including misdiagnoses as dementia, and illustrate how white matter tractography and awake surgery contribute to understanding and preserving cognitive networks. We also present cases of glioma patients whose cognitive function improved following awake surgery, and others in whom functional impairment remained due to surgical limitations or limited plasticity. Comprehensive preoperative assessment and tailored surgical planning are essential for optimizing both survival and neurocognitive outcomes in patients with brain tumors.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 5","pages":"988-998"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although memory impairment is also present, recognition memory is often preserved, distinguishing iNPH from Alzheimer's disease (AD). Behavioral and psychological symptoms of dementia (BPSD), especially apathy, depression, and anxiety, are common in iNPH and are generally less active than those seen in AD. Neuropsychological assessments reveal significant impairments in frontal lobe tests such as the Frontal Assessment Battery and Trail Making Test-B. Shunt surgery leads to substantial improvement in attention and executive function, reflecting the reversible nature of iNPH. However, memory functions, particularly delayed recall, show limited recovery, indicating possible overlap with neurodegenerative mechanisms. Early surgical intervention is associated with better outcomes, while delayed treatment or advanced brain atrophy may reduce effectiveness. Comprehensive cognitive evaluation is essential for assessing treatment response, planning rehabilitation, and providing appropriate patient and family guidance.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 5","pages":"969-974"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2018, in response to the needs of an increasingly aging society, the Society broadened its mission to include dementia prevention, adopting the subtitle \"A Medical Society for the Prevention of Stroke and Dementia.\" Although brain dock examinations are not covered by public health insurance and are offered as self-funded services, they have become widely accepted as a form of preventive medicine in Japan. This acceptance is supported by high public health awareness and proactive participation from municipalities and corporations. Among OECD countries, Japan has the highest number of MRI units per capita, ensuring easy access to neuroimaging and facilitating the detection of asymptomatic brain diseases. Consequently, Japan has already amassed a substantial volume of brain dock data. Recent rapid advances in artificial intelligence (AI) are now being applied to the brain dock field, particularly for the early diagnosis of dementia. This article explores how brain dock programs are integrating AI technologies and how they are expected to contribute to the early detection and prevention of dementia.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 5","pages":"932-941"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate differential diagnosis of these disorders requires clarification of their clinical characteristics. The initial symptoms of DAT typically include recent memory loss, episodic memory impairment, and temporal disorientation. Behavioral and psychological symptoms often observed in DAT include delusions of theft, \"saving appearance\" responses, and head-turning signs. Vascular dementia develops in association with cerebrovascular disease and frequently exhibits a stepwise progression. DLB is characterized by core clinical features such as cognitive fluctuations, visual hallucinations, parkinsonism, and REM sleep behavior disorder. Diagnostic tools such as 123Iodine-metaiodobenzylguanidine (MIBG) myocardial scintigraphy and dopamine transporter (DAT) imaging may aid in diagnosis. In Parkinson's disease with dementia (PDD), cognitive impairment appears more than one year after the onset of parkinsonism. FTLD involves degeneration of the frontal and temporal lobes, leading to prominent changes in personality, behavior, and language function. Several subtypes of FTLD exist depending on the affected brain region, including the behavioral variant of frontotemporal dementia, semantic dementia, and progressive non-fluent aphasia. Idiopathic normal-pressure hydrocephalus (iNPH) is characterized by gait disturbance, urinary incontinence, and dementia, resulting from an abnormal accumulation of cerebrospinal fluid. Pathologically confirmed cases of DLB and progressive supranuclear palsy (PSP) may occasionally present with symptoms resembling iNPH.","PeriodicalId":35984,"journal":{"name":"Neurological Surgery","volume":"53 5","pages":"853-862"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
