The wearable device for epilepsy patient has three main purposes: 1) Seizure detection, 2) seizure alarming and 3) recording of 30–60 seconds pre-ictal and ictal EEG signals for precise diagnosis.
Thus, the development of a smart headband for the epilepsy patients is paramount importance. Therefore, a wearable seizure detection headband system is desirable to avoid the aforementioned emergent medical situations and complicate surgical procedure. Thus, all the above works can only focus on post-ictal seizure detection or alarming. However, for seizure detection, the EEG signals are the most direct bio-potential signal. These devices use ECG, EMG or body motion –, to detect seizure. Several wearable devices have been developed for seizure detection –. The other 70% patients who are taking antiepileptic drugs still suffer from accidental epileptic seizures and its consequences. The implanted devices will only benefit the 30% patients with drug resistant epilepsy.
However, implementing the implantable devices requires a complicated, high cost and time consuming surgical procedure. To overcome the above limitations, researchers –, proposed a close-loop epilepsy prosthesis device with temporospatial seizure detection and therapeutic stimulation responsively. The periodical operations for clients are necessary to replace the battery and devices. Besides, by using battery with continuous stimulations, the lifetime of such a device is quite limited. These devices use the open-loop continuous neural stimulations to control medical refractory epilepsies complementarily with the limited effective rate around 45%. Several prosthesis devices with deep brain stimulation, become popular clinical solutions. In recent years, alternative treatments and devices are proposed to investigate and treat epilepsy in addition to pharmacological and surgical treatments. Nevertheless, the patients above will still suffer seizures occasionally, which will affect the patients’ quality of lives, and further trigger dangers to patients themselves and the people around them.
The other therapy is to remove the epileptogenic zone by the resection surgery. One of the treatments is to use antiepileptic drugs to control epileptic seizure, but nearly 30% of the patients are resistant to epileptic medicine. About 65 million people in the world are affected. Epilepsy is one of the most common neurological disorder.
