Senescence itself bears risks of pathologies which in the form of acute focal damage (e.g. stroke) or slowly progressive degenerative damage can cause seizures and substantial cognitive impairment. There is converging evidence from studies in LOE that cognitive impairments are present from epilepsy onset before treatment is initiated and may even precede the emergence of seizures. This suggests that these impairments (like the seizures) are expressions of the underlying disease. Indeed, both seizures and cognitive impairments can be early indicators of disease conditions which lead to mental decline. Cognitive decline over time poses the challenge of disentangling the interrelation between seizures, treatment effects and underlying disease. This issue must be considered as some of the etiologies for causing neuropsychological decline can be addressed. Medication and active epilepsy can contribute to impairments and their impact may be reversible. Dementia is rare if seizures are what has brought the person to attention, and if this is not accompanied by other slowly developing features (such as cognitive of psychiatric changes). From a neuropsychological point of view choosing the right screening tools or assessments, obtaining the history and timeline of impairments in relation to epilepsy, and most importantly longitudinally following the patients regardless of whether epilepsy is ultimately controlled or not appear essential.</div></div>","PeriodicalId":49552,"journal":{"name":"Seizure-European Journal of Epilepsy","volume":"128 ","pages":"Pages 16-19"},"PeriodicalIF":2.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140330268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brain abnormalities regularly seen on MRI of older adults are atrophy, and changes related to small vessel disease (SVD). SVD-related changes include white matter hyperintensities (WMH), lacunes, microbleeds, microinfarcts and perivascular spaces. While atrophy, WMH and lacunes are recognized as important contributors to cognitive decline and dementia, relationships are less clear for microbleeds, microinfarcts and perivascular spaces. Vascular risk factors are considered critical in the development of these changes and being potentially modifiable have become increasingly interesting to researchers and clinicians alike. Managing vascular risk early, particularly hypertension, is a key factor in slowing down the evolution of age-related brain abnormalities and decelerate their detrimental cognitive consequences. Cognition and visible brain abnormalities have a complex relationship, which reaches far beyond what we can understand using standard MRI. Remote effects of lesions and associated- as well as independent network changes likely explain much of the different cognitive trajectories observed with aging. Because of the versatility of MRI in the diagnostic of various diseases, including epilepsy, incident signs of brain aging will be encountered ever more frequently on standard MRI of older adults. To facilitate understanding and ultimately reporting these changes to patients, this review will give a brief overview of MRI findings encountered on MRI of older people.

Unlike epilepsy in younger individuals, LOE is almost by default focal in origin, secondary to acquired etiologies, and presents unique diagnostic and management challenges due to its atypical semiology, higher comorbidity burden, frailty, and increased risks of subsequent stroke and dementia. LOE clinics have been established to address these challenges, providing a multidisciplinary approach to optimize outcomes in patients with new-onset seizures beyond the fifth decade of life. LOE clinics are essential for comprehensive care, offering not only seizure management but also monitoring and addressing associated comorbidities.
