Memory loss in older adults may stem from unrecognized complex partial seizures, not dementia. Early diagnosis of these seizures is crucial for appropriate treatment in the elderly.

Area of Science:

Neurology
Geriatrics
Epileptology

Background:

Dementia is a common cause of age-related memory loss.
Complex partial seizures (CPS) incidence increases significantly after age 60.
Subtle or nocturnal CPS can be difficult to identify.

Observation:

Five elderly patients presented with memory dysfunction, initially suspected as dementia.
These patients' memory issues were attributed to undiagnosed complex partial seizures.
The subtle nature of seizures in the elderly can mask underlying neurological conditions.

Findings:

Unrecognized complex partial seizures were the cause of memory dysfunction in all five patients.
Memory impairment in the elderly can be a presenting symptom of subtle-onset epilepsy.

Diagnostic challenges exist in identifying non-convulsive seizures in older populations.

Implications:

Highlights the importance of considering epilepsy in elderly patients with memory complaints.
Suggests a need for increased awareness and diagnostic vigilance for complex partial seizures in geriatric populations.
Undiagnosed seizures can lead to misdiagnosis and delayed treatment, impacting patient outcomes.
