Abstract

The invention provides a waveform generation device for transcranial alternating current stimulation, and relates to the technical field of transcranial alternating current stimulation. The waveform generation device comprises: a first waveform generation circuit, which is used for generating a theta wave signal with a first waveform; a second waveform generation circuit, which is used for generating a gamma wave signal with a second waveform; and a composite circuit, which is used for superposing the gamma wave signal at the wave crest of the first waveform to obtain a composite wave signal for each period of the theta wave signal, wherein the composite wave signal is used as a stimulation signal of transcranial alternating current stimulation of an Alzheimer&aposs disease patient. The waveform generation device provided by the invention has the following beneficial effects: the composite wave signal is formed through multi-frequency-band coupling; through a stimulation mode that multi-brain-region stimulation is simultaneously carried out through a plurality of output electrodes, a neural regulation mechanism related to working memory and an effective plastic neural pathway can be further improved; and thus, healthy elder people, people with mild cognitive impairment and people with Alzheimer&aposs disease are helped to improve the working memory ability and cognitive ability.

Description

technical field [0001] The invention relates to the technical field of transcranial alternating current stimulation, in particular to a waveform generating device for transcranial alternating current stimulation. Background technique [0002] The degree of degeneration of working memory in Alzheimer's disease (Alzheimer's disease, AD) population is particularly prominent, so it has also become an effective means for early screening of AD. Mild cognitive impairment or mild cognitive impairment (Mild Cognitive Impairment, MCI), as a state of cognitive impairment between normal aging and dementia, can be divided into amnesic MCI (amnesic MCI) according to the cognitive domain involved. , aMCI) and non-amnesic MCI (naMCI), aMCI specifically refers to cognitive impairment mainly memory impairment. About 10-15% of aMCI develop into AD) the proportion is much higher than that of naMCI and healthy elderly. AD is progressive and there is currently no effective treatment. Early dete...
