The Dementia Seizure Spectrum™ (DSS) Framework, in the open: four domain guides for organizing observable changes, an evidence-informed evaluation method, an implementation protocol, and educational resources for understanding patterns that may warrant clinical review.
These resources support education and structured communication. They do not determine that an observed event was a seizure.
The Dementia Seizure Spectrum™ (DSS) Framework organizes observable events across four domains: Seizure Events, Movement Changes, Awareness Changes, and Behavioral Changes. Begin with the domain most relevant to the observation, while recognizing that one event may involve several domains.
The domains describe what was observed, not what caused it.
Observable events that may resemble conventionally recognized seizure presentations, including loss of consciousness, tonic stiffening, rhythmic jerking, or sudden loss of postural control. Document the exact event, context, duration, responsiveness, and recovery.
Read the domain →New, abrupt, episodic, or stereotyped movement changes, such as lip-smacking movements, repetitive hand activity, rhythmic movement, or sudden stiffening. Similar observations may have neurological, medication-related, behavioral, or metabolic explanations.
Read the domain →Sudden unresponsiveness, blank staring, unexplained confusion after an episode: the most frequently missed presentations in dementia care.
Frequently missed Read the domain →Explosive, unprovoked fear, aggression, or confusion followed by unusual exhaustion: most often misattributed to sundowning or behavioral symptoms of dementia.
Most often misattributed Read the domain →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.
The DSS Framework organizes what was observed across four domains. DSEF evaluates the event pattern, background context, competing explanations, and safety conditions. SeizureSafe™ translates the structured evaluation into response and follow-through pathways. CRISP™ supports the evidence architecture across the system.
The DSS Framework is designed to function across education, structured evaluation, response protocols, research, and technology integration. The resources below demonstrate how the observation architecture can be translated into usable tools while the methods remain under expert review and validation.
These public resources are educational and pre-validation. Licensed integrations may use additional structured logic, evidence intelligence, and implementation assets.
An illustrative model showing how changes in observation practices, documentation, and follow-up assumptions can affect the number of events identified in a simulated care population. The simulator is educational and does not estimate individual or population-level seizure prevalence.
Explore the simulation →A structured, non-diagnostic evaluation that combines DSS domain observations with background risk, event pattern, contextual features, competing explanations, documentation quality, and safety conditions. The current public version is educational and pre-validation and produces a structured summary for qualified review.
Explore DSEF →A four-step response and implementation protocol: Recognize, Respond, Document, and Advocate. SeizureSafe translates structured observations and DSEF findings into safety, documentation, communication, escalation, and follow-through pathways.
The open protocol supports education; configurable workflow logic and implementation assets may be licensed through strategic partnerships.
Explore the protocol →The field guides and core educational resources are available for learning and structured communication. Organizations seeking to incorporate Seagull Health's observation architecture, evaluation logic, response pathways, or evidence intelligence into products, platforms, or research programs can explore licensing and strategic collaboration.
The Seagull Health Knowledge Base provides educational resources for observation, documentation, research, and clinical 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.
