Portable magneto-optical stimulation device for improving cognitive impairment of Alzheimer's disease

Abstract

The invention provides a portable magneto-optical stimulation device for improving cognitive impairment of Alzheimer's disease, which is head-mounted and comprises a magnetic field coil, a coil bracket, an LED light source, a light source bracket, a bracket shaft, a power supply and signal two-in-one wire, a rechargeable power supply, a master controller, a magnetic field coil driver and an LED light source driver. The device can generate a pulsed magnetic field and a pulsed light signal with the frequency of 4 Hz to 90 Hz, can tune and enhance a gamma frequency band and a theta frequency band of brain waves of a patient suffering from the Alzheimer's disease, and can simultaneously regulate and control nerve excitability of different functional brain areas of temporal lobe and occipital lobe by simultaneously performing magnetic stimulation and light stimulation. On the basis of interaction of neuroplasticity and a functional brain region neural network, cognitive-related multifunctional brain region neural activities are synergistically enhanced, and the function of improving the learning and memory cognitive ability of a patient is achieved. The device is similar to an earphone in appearance, is small and light, is convenient for a patient to wear, does not affect daily actions of the patient, and can realize two treatment modes of hospitalization and home use.

Description

technical field [0001] The invention relates to the technical fields of neuromodulation technology, magnetic stimulation technology, optical stimulation technology and medical equipment, in particular to a portable magnetic and optical stimulation device, in particular to a rehabilitation aid for improving the cognitive impairment of Alzheimer's disease patients. Background technique [0002] Studies have shown that Aβ amyloid accumulates in the brain of patients with Alzheimer's disease. Drug treatment is often used in clinical practice, but the effect is not obvious and there are adverse reactions. In addition, because the gamma frequency band (30-80Hz) of brain waves in patients with Alzheimer's disease is damaged, the gamma frequency band has been proven to be closely related to cognitive functions such as learning and memory of the brain. Another study showed that applying transcranial electrical stimulation in the θ frequency band (4-8Hz) to patients with Alzheimer's d...

Problems solved by technology

However, most of the existing auxiliary devices are single magnetic stimulation (such as transcranial magnetic stimulation) or sound and light stimulation, and most of them are in the gamma frequency band. There is no portable device with both magnetic stimulation and light stimulation, and the frequency coverage The γ and θ frequency bands meet the needs of patients to use these two physical factor stimulation at the same time anytime and anywhere, and improve the therapeutic effect
