Learn how seizures can look in each dementia type
Subtype Atlas
How seizures can appear in Alzheimer’s, Lewy body, frontotemporal, vascular and mixed dementia, and what else they can be mistaken for.

Seizures in dementia can be difficult to recognize. The details that matter are often not captured.
Seagull Health helps people and organizations capture what was observed, compare the full pattern with dementia-seizure research, and bring a clearer account to the people responsible for what happens next.
Seagull Health works with care organizations, caregiving platforms and health-technology companies.

Why this matters
A new episode deserves a clear description.
A pause in speech, a change in response, or an unusual movement can be hard to interpret when someone is living with dementia. Seizures are one possible explanation. Illness, fainting, medication effects, sleep, and dementia-related changes can also matter.
A memory-clinic study found that some subtle seizure events had been noticed but attributed to dementia. Its findings show a recognition problem in that setting; they do not establish the cause of any one person's episode.
From an observation to a useful account
Keep the details of the episode together.
Illustrative example. This describes an invented episode and is not a DSEF result.
What someone noticed
“She stopped talking and stared ahead.”
That observation starts the account. Timing, responsiveness, recovery, and what remains unknown give it context.
An account with more detail
“During lunch, she stopped speaking and stared ahead. She did not answer two questions for about 40 seconds. Then she resumed speaking. A similar episode was noticed yesterday.”
This account preserves what happened without assigning a cause. Whether she returned fully to her usual state remains a question to clarify.
DSEF helps organize a reported episode and its context into an educational summary. See how DSEF works →
