Adults with frontotemporal dementia are at increased risk of seizures, per a study from the University of California, San Francisco.
The study analyzed 239 people meeting criteria of frontotemporal dementia to determine seizure incidence. Their results found that 2.2% of patients had seizures and 6.5% had myoclonus, the involuntary jerking of a group of muscles.
However, the patients with frontotemporal dementia had higher incidence of both seizures and myoclonus than the general population. Seizures in older adults may happen up to five years before dementia diagnoses.
