Abstract

INTRODUCTION: Patients with epilepsy and their caregivers are constantly burdened with the possibility of a seizure and its consequences, such as accidents, injuries, and sudden unexplained death in epilepsy. It is the unpredictable nature of seizures that often affects both patients with seizures and their caregivers, limits independence, and hinders quality of life. There are several types of motion detectors on the market, each with varying degrees of sensitivity. MATERIAL AND METHODS: We prospectively tested the SmartWatch, a wrist-worn monitor, on children, adolescents, and young adults with various types of seizures in an epilepsy monitoring unit. Confirmation of seizure type and if there was rhythmic upper extremity jerking associated with the seizure was determined by review of the video electroencephalograph. This was compared with the standard detection system of the watch.

RESULTS: This study analyzed a total of 191 seizures in 41 patients aged 5-41 years. Fifty-one of the seizures were generalized tonic-clonic. Forty-seven of the seizures had a rhythmic arm movement component. The SmartWatch detected 30 seizures (16%) of the total, 16 (31%) of the generalized tonic-clonic seizures, and 16 (34%) seizures associated with rhythmic arm movements.

DISCUSSION: Overall, only a minority of generalized tonic-clonic seizures or seizures with rhythmic movements were detected, highlighting the need for an effective seizure detection device.
