AI Technical Summary

Technical Problem

When the existing transcranial AC stimulation technology treats brain diseases such as Alzheimer's, it is difficult to arrange electrodes, resulting in discomfort and poor treatment compliance, making it difficult to provide comprehensive and gentle treatments to multiple brain areas, and it is difficult to target and precise treatment of deep areas such as the hippocampus.

Method used

The phototherapy part and the AC transcranial electrical stimulation part are combined. The phototherapy part irradiates transcranial near-infrared light to the frontal lobe, temporal lobe and parietal lobe. The AC transcranial electrical stimulation part uses the first and second scalp electrode pairs to form a high-frequency AC oscillation electric field, with a frequency difference of 10Hz-80Hz, which acts synergistically on the deep part of the target.

Benefits of technology

It achieves gentle and comfortable treatment for multiple brain areas, reduces the psychological pressure of patients, and can perform targeted enhanced stimulation of deep areas such as the hippocampus, widely reduces shallow lesions, and enhances the therapeutic effect on Alzheimer's disease.

Abstract

The present application provides a transcranial physical stimulation device, which includes at least a phototherapy unit and an AC transcranial electrical stimulation unit. The phototherapy unit is configured to irradiate transcranial near-infrared light to at least the frontal lobe, temporal lobe, and parietal lobe of the subject's head. The AC transcranial electrical stimulation unit includes a first scalp electrode pair and a second scalp electrode pair. The first scalp electrode pair forms a first electric field and acts on a target deep part. The second scalp electrode pair forms a second electric field and acts on the target deep part. The first electric field and the second electric field are AC oscillating electric fields applied simultaneously, with a frequency of more than 1000 Hz and a frequency difference of 10 Hz-80 Hz. The device is easy to operate and can provide comprehensive, gentle, and comfortable transcranial physical therapy for multiple brain areas involved in AD. It can also coordinate transcranial alternating current (tACS) to provide targeted and precise treatment of deep parts of the brain such as the hippocampus.
