Knowledge · The public intelligence layer
Understand the field behind dementia-related seizures.
Seagull Health's Knowledge Base brings together the dementia-seizure atlas, the DSS domain model, four domain guides, DSEF, and SeizureSafe. Explore the evidence by dementia type, understand how events can present, and follow the questions shaping detection research.
Use it to learn the shared language, explore how the capabilities connect, and find the path most relevant to your question or work. These resources support understanding and communication; they do not determine that an event was a seizure.
Start with the dementia type. Follow the evidence.
Five guides bring together clinical seizures, events without obvious outward signs, EEG findings, and recognition challenges across Alzheimer's disease, dementia with Lewy bodies, frontotemporal dementia, vascular dementia, and mixed dementia.
Seagull connects this evidence with the questions better detection must answer. What might be overlooked? What can a recording actually detect? Which findings matter to the person, and what must a new method demonstrate before it can improve care?
The atlas gives clinicians, researchers, healthcare leaders, and AI developers a shared starting point for those questions. Its Research insights page distinguishes dementia studies from related epilepsy research, and promising technology from demonstrated clinical benefit.
This is an educational evidence resource. It does not analyze EEG recordings or diagnose events, and it remains separate from DSEF and DSEF for Organizations.
One maintained model. Four connected domains.
The Dementia Seizure Spectrum™ (DSS) provides shared language across Seizure Events, Movement Changes, Awareness Changes, and Behavioral Changes. The domain guides explain the observations, contextual questions, and competing explanations associated with each part of the model.
One event may involve one domain or several. The domains describe what was observed, not what caused it.
Seizure Events
Observable events associated with more conventionally recognized seizure presentations, including changes in consciousness, tonic stiffening, rhythmic jerking, or sudden loss of postural control.
Read the domain →Movement Changes
Abrupt, episodic, or stereotyped movement changes such as lip-smacking, repetitive hand activity, rhythmic movement, or sudden stiffening.
Read the domain →Awareness Changes
Sudden or episodic changes in responsiveness, engagement, communication, or awareness, including blank staring, behavioral arrest, or speech interruption.
Read the domain →Behavioral Changes
Abrupt, episodic, or stereotyped changes in behavior, affect, language, or purposeful activity that require careful contextual interpretation.
Read the domain →Replace assumptions with observable detail.
Broad labels such as "confused," "agitated," "restless," or "had a spell" may omit the details needed for evaluation. The first step is not to assign a neurological cause. It is to describe what changed, when it began, how long it lasted, how the person responded, and how recovery unfolded.
One architecture, with a distinct job for each capability.
DSS models the domain. DSEF applies evidence-linked evaluation to the broader pattern. SeizureSafe supports practical follow-through. The Knowledge Base makes the language, concepts, and public resources accessible across disciplines, settings, and countries.
Choose the path that fits your purpose.
The knowledge layer is not a single reading sequence. Visitors can explore the evidence and domain language, evaluate a documented pattern, understand practical follow-through, or connect the intelligence to an organizational use case.
DSEF
Use a transparent, non-diagnostic, evidence-linked evaluation to organize a documented event pattern and its surrounding context.
Start a free DSEF evaluation →DSEF for Organizations Build
Start with one paid, fixed-scope episode-to-handoff workflow in a partner-controlled nonproduction sandbox.
See the fixed scope →SeizureSafe™
Connect structured understanding to recognition, immediate safety, precise documentation, communication, escalation, and next steps.
Explore SeizureSafe →Recognizing Possible Seizures in Dementia
A ready-to-run workshop that teaches a team to notice an unusual episode, describe what was seen, and route it to the right person. Free to work through; a $199 facilitator license to lead it.
Open the workshop →The Seagull Health Knowledge Base provides educational resources for understanding, observation, documentation, research, and communication. It does not diagnose seizures, determine that an observed event was seizure-related, assign an individual probability, select a diagnostic test, or recommend treatment. Similar observations may have neurological, cardiovascular, infectious, medication-related, sleep-related, metabolic, psychiatric, environmental, or dementia-related explanations. Emergency and clinical decisions require qualified judgment and applicable local protocols.
