ABSTRACT

Objective:

To analyze the prevalence of epilepsy and its clinical features in patients with Alzheimer's disease(AD).

Methods:

Clinical data of patients with AD from a separate database of Tianjin Huanhu Hospital for dementia and degenerative diseases from January 2010 to January 2019 were retrospectively examined.The prevalence of AD combined with epilepsy was analyzed.The characteristics from neuropsychological assessment, clinical manifestations of epileptic attacks, electroencephalogic patterns and other features were analyzed and compared with those of AD patients without epilepsy.

Results:

Of 376 AD patients, 11.4% had epilepsy, with 4.0% showing non-induced seizures before AD diagnosis and 7.5% after AD diagnosis.The average age of AD patients at first onset of epilepsy was 59.8±19.9 years, and the average age of patients at initial diagnosis with AD was 62.8±6.6 years.The most common type was focal seizures(65.1%), and EEG showed mostly focal slow waves(69.8%)and focal epileptiform discharges(23.3%). The AD diagnosis for patients with epilepsy was 8 years earlier than those without epilepsy.

Conclusions:

Epilepsy has a high prevalence in AD patients, and seizures may be a risk factor for progression from cognitive impairment to AD.Early identification of seizures and cognitive impairment may have a positive effect on delaying the progression of dementia.
