A visual thermodynamic diagram is generated through the interpretability analysis module to enhance the interpretability of diagnosis, the accuracy of early detection of Alzheimer's disease is improved to 92%, the reasoning speed is improved by 3-5 times, and a key time window is provided for early intervention and treatment.

The present application relates to a neuromodulation device for treating hippocampus-related brain diseases. The neuromodulation device comprises a phototherapy part and a transcranial alternating current stimulation (tACS) part. The phototherapy part irradiates near-infrared light toward at least a frontal lobe or a temporal lobe, such that the near-infrared light acts on at least a part of the hippocampus. The tACS part applies tACS of a second frequency, and an electric field action range covers at least a part of the hippocampus. When the near-infrared light is continuous light, the second frequency is in one of five representative frequency bands of brain waves. When the near-infrared light is pulsed light having a first frequency, the first frequency and the second frequency also satisfy a preset frequency relationship. The preset frequency relationship comprises: a deviation being less than a threshold, or having a preset frequency band coupling relationship. Transcranial electrical stimulation can produce analgesic and relaxing effects, which can reduce the discomfort of a subject during treatment. Therefore, the treatment time can be prolonged and / or the power density of near-infrared light can be increased as needed, so as to improve the therapeutic effect. The photoelectric bimodal stimulation can improve modulation effects on endogenous oscillations of the brain.

The present application provides a transcranial physical stimulation apparatus for treating diseases related to a target site of the brain. The transcranial physical stimulation apparatus at least comprises a phototherapy part and an alternating current transcranial electrical stimulation part. The phototherapy part irradiates transcranial near-infrared light onto at least a frontal lobe and a temporal lobe of the head of a subject, or irradiates transcranial near-infrared light within an irradiation range containing the target site and a peripheral brain region thereof. The alternating current transcranial electrical stimulation part comprises a first scalp electrode pair and a second scalp electrode pair. A pair of electrodes constituting the first scalp electrode pair forms an electric field of a first frequency and acts on the target site, and a pair of electrodes constituting the second scalp electrode pair forms an electric field of a second frequency and acts on the target site. The second frequency is greater than the first frequency, and the ratio of the frequency difference to the first frequency is 8% or less, and the frequency difference is within the range of 1 Hz to 80 Hz. The apparatus performs, by means of near-infrared light, comprehensive, gentle, and comfortable transcranial physical treatment on a plurality of disease-related brain regions, and performs, by means of transcranial alternating current, precise targeted treatment on a disease-related target site; the two cooperate synergistically to enable a better therapeutic effect.
