Clinical Intelligence · Seizure Clarity in Dementia
Up to 40% of seizures in Alzheimer's produce no visible signs. They surface as blank stares, sudden mood shifts, and unexplained unresponsiveness — and they are being missed in nursing-home records, care portfolios, and clinical trials worldwide.
The Clinical Gap
A sudden mood shift. An episode of unresponsiveness that clears on its own. In a person with dementia, these are recorded as agitation, sundowning, natural decline — a behavioral note and a medication adjustment.
The peer-reviewed evidence establishes that the same signals are documented seizure presentations requiring neurological evaluation. That gap — between what is observed and what was knowable — is where Seagull Health works.

The Name
The Dementia Seizure Spectrum classifies how seizures actually present in dementia across four domains — so a nurse can chart it, a family can say it, and an expert can defend it.
Dementia Seizure Spectrum™
The Measurement
CRISP searches and scores the published clinical literature against the framework, producing structured intelligence calibrated to the exact decision in front of you.
CRISP™ Intelligence Engine
The Consequence
The same finding, translated into the stake each decision-maker already holds — clinical documentation, facility risk, and research design.
Delivered briefs & SeizureSafe™ protocols
A standard helps no one if it stays in a drawer. The Dementia Seizure Spectrum is published in full: a field guide to the seizures that don't look like seizures, a simulation of what goes unseen, a national index, and an evaluation anyone can run.
How seizures actually present in dementia. Recognize, document, and respond, domain by domain.

She didn't just lose her train of thought. She was experiencing a seizure that most of us have never been taught to recognize.
This scene plays out every day, in living rooms and care homes all over the world. No one should have to disappear into that silence alone. The Manifesto is what we stand for, and why a standard for this had to exist.
Dementia Seizure Spectrum™
The clinical taxonomy — four domains describing how seizures present in dementia, person-level and setting-agnostic by design.
SeizureSafe™
The implementation layer — how care teams recognize, respond, document, and advocate once a risk is identified.
CRISP™
The engine — searching and scoring the published literature to produce the brief a specific decision requires.
The Dementia Seizure Spectrum™ is the clinical foundation. SeizureSafe™ is how you use it. CRISP™ is how we know.
A seizure no one was trained to see is not behavior. It is a missed diagnosis — in every country where people grow old. Read what we stand for.
