Sources, scope, and uncertainty
Evidence behind the exercises.
The workshop teaches a Seagull-designed observation and communication structure. Published research and guidance support its background statements. They do not validate this curriculum, its questions, or its scores.
How subtype context is used
| Context | Educational application | Boundary |
|---|---|---|
| Alzheimer’s disease | Keep a brief episode separate from ongoing memory difficulty. | Describe the person’s usual response and activity, then the beginning, sequence, and recovery of the new episode. An Alzheimer’s diagnosis does not establish that a pause is a seizure. |
| Dementia with Lewy bodies | Compare an episode with the person’s usual fluctuations. | Attention and alertness may fluctuate in DLB. A new episode still needs its own description; neither “a fluctuation” nor “a seizure” can be concluded from a pause alone. |
| Frontotemporal dementia | Use the person’s familiar way of communicating as the baseline. | FTD can affect language or behavior. Existing speech difficulty and repetitive actions can complicate an account. Describe whether familiar nonverbal responses changed as well. |
| Vascular dementia | Separate established effects of injury from a sudden new change. | An old stroke-related difficulty does not explain away a new focal change. Sudden face, arm, or speech changes require the emergency pathway; do not wait to establish their cause. |
| Mixed dementia | Record the known combination and what remains uncertain. | More than one disease or injury may contribute. Preserve the documented conditions and the episode itself. Do not add subtype percentages together or select a single cause from the label. |
Primary research and professional guidance
- CDC. First aid for seizures.
General first-aid and emergency-call guidance; not a dementia-specific triage score or a diagnosis.
- Beagle et al. (2017). Relative incidence of seizures and myoclonus in AD, DLB, and FTD. In the Evidence Map →
Retrospective specialty-clinic research: seizures and myoclonus are distinct outcomes. Does not diagnose a fictional case or provide an individual risk score.
- McKeith et al. (2017). Fourth consensus report of the DLB Consortium. In the Evidence Map →
Consensus guidance supports the DLB context of fluctuating cognition and episodes of reduced responsiveness; these features are not seizure-specific.
- Brazilian Academy of Neurology (2022). Recommendations for the diagnosis of frontotemporal dementia.
Describes behavioral and language presentations. Used for baseline context, not for subtype-specific seizure prediction.
- CDC (2026). Signs and symptoms of stroke.
Supports calling 911 immediately for sudden stroke signs in the US and preserving symptom-onset time. It is emergency guidance, not a vascular-dementia seizure study.
- NICE NG217. Diagnosis and assessment of epilepsy.
General epilepsy guidance values eyewitness history and cautions against using EEG to exclude epilepsy. Not a validation of this workshop.
- Hirsch et al. (2021). ACNS standardized critical care EEG terminology. In the Evidence Map →
Distinguishes EEG findings; an electrical discharge or slowing must not be relabeled as a recorded seizure. Clinical interpretation belongs to qualified professionals.
Seagull supporting resources
- Main site — observation before causal interpretation, and how DSS, DSEF, and SeizureSafe relate.
- Dementia-Seizure Subtype Atlas — the five subtype guides and their evidence boundaries. The mixed-dementia framing draws on this synthesis; the workshop does not claim a single mixed-dementia seizure pattern.
- Atlas methods — selected evidence synthesis with disclosed review limitations.
What the results mean
The starting and final exercises each carry three structured questions on baseline comparison, observable facts, and uncertainty. Scores count first responses matching the teaching answer. The cases differ, and difficulty equivalence has not been established. Discussion, familiarity, and case differences may all affect results. Documentation is self-reviewed against a model account.
We do not infer seizure probability, changes in clinical outcomes, or staff competence. A visible pause is not proof of an EEG seizure; a brief epileptiform discharge and background slowing are also different findings.
