Clinical Scorecard: The Link Between Seizure Management and Neuropathological Changes in Dementia
At a Glance
Category
Detail
Condition
Seizures in people with dementia (PWD) and their association with neuropathological changes
Key Mechanisms
Neuronal hyperexcitability, accumulation of pathological tau and beta-amyloid aggregates, impaired glial and inhibitory neuron function leading to increased seizure susceptibility and neurodegeneration
Target Population
People with dementia experiencing active, remote, or no seizures
Care Setting
Multicentre Alzheimer’s Disease Research Centres and clinical dementia care settings
Key Highlights
Active seizures in PWD are associated with earlier death and more severe dementia compared to remote or no seizures.
Post-mortem findings show that active seizures correlate with more advanced Alzheimer’s disease pathology (amyloid, tau, neurodegeneration) and worse AD co-pathology in non-AD dementias.
Frontotemporal lobar degeneration pathology is less prevalent in active seizure participants, while vascular, Lewy body, and other pathologies show no significant differences among seizure groups.
Guideline-Based Recommendations
Diagnosis
Clinicians should vigilantly detect ongoing seizures in PWD as they indicate worse prognosis and more severe neuropathology.
Management
Effective seizure control may be critical to potentially mitigate accelerated cognitive decline and neurodegeneration in PWD.
Monitoring & Follow-up
Regular cognitive and functional assessments should be conducted in PWD with seizures to monitor progression and adjust care accordingly.
Risks
Active seizures increase mortality risk and are associated with more severe Alzheimer’s disease and neurodegenerative pathology.
Patient & Prescribing Data
Deceased people with dementia categorized by seizure status (active, remote, no seizures)
Active seizures correlate with worse clinical outcomes and neuropathology, underscoring the importance of seizure management in dementia care.
Clinical Best Practices
Screen for and document seizure activity regularly in PWD to identify active seizures promptly.
Consider the potential impact of seizures on dementia progression when planning treatment and care strategies.
Use multidisciplinary approaches including neurology and geriatrics to optimize seizure control and dementia management.
Educate caregivers and patients about the implications of seizures in dementia and the importance of adherence to treatment.
