Description

Alzheimer disease prevention and treatment device and implementation method thereof

Technical Field

The invention relates to the technical field of medical instruments, in particular to an Alzheimer disease prevention and treatment device and an implementation method thereof.

Background

Alzheimer disease is a nervous system degenerative disease with progressive development with hidden diseases, the pathological changes can affect multiple systems such as nerves, movement, urinary system and the like, cognitive function is reduced, behavior disorder, life ability is reduced and the like, and depression, anxiety, psychosis and the like are frequently complicated, so that patients gradually lose self-care ability, and families are greatly affected. At present, the examination mainly comprises neuropsychological test, hematology examination, neuroimaging examination, electroencephalogram, cerebrospinal fluid detection, gene detection and the like. The diagnosis is mainly carried out according to the signs of the symptoms of the patients, magnetic resonance display, abnormal cerebrospinal fluid biomarkers, clear gene mutation in relatives and the like. The core diagnostic criteria include: 1. early and significant episodic memory impairment; 2. atrophy of the medial temporal gyrus; 3. an abnormal cerebrospinal fluid biomarker, an elevated β amyloid 1-42(a β 1-42) concentration, an elevated total Tau protein concentration, or an elevated phosphorylated Tau protein concentration, or a combination of the three; specific imaging of PET functional nerve images, bilateral temporal and apical lobe glucose metabolic rate reduction; 5. there are clear AD-associated autosomal dominant mutations in the orthotopic relatives. The treatment policy is to control the accompanying psychopathological symptoms, improve the cognitive function and delay the disease progress.

At present, the treatment modes for senile dementia patients at home and abroad are drug treatment and behavioral correction. The treatment requires symptomatic treatment, with the aim of controlling the accompanying psychopathological symptoms, the use of anxiolytics, antidepressants, antipsychotics, nootropic or cognitive function-improving drugs: drugs acting on neurotransmitters, and drugs that activate brain metabolism. In addition to drug therapy, there is a need for scientific correction of the patient's behavior, i.e. non-drug therapy, mainly including mediterranean diet, exercise therapy, phototherapy, acupuncture therapy, music therapy, stress reduction, increased socialization, attention to sleep hygiene and training to receive knowledge of dementia.

Research and clinical findings show that although the drug therapy is used as a main treatment method, no radical drug exists, all drugs can only improve the cognitive condition of patients for a short time, the post-treatment of patients with severe dementia is relatively troublesome, and the curative effect of the drug is weakened or even ineffective. The treatment with antipsychotics is not helpful in improving cognitive function, but it can control the mental symptoms of the patient, such as anxiety, irritability, emotional instability, hallucinations, etc., which are troublesome to the care of the subjects and require the use of such drugs to control the mental symptoms. The non-drug therapy plays an important auxiliary role in treating the senile dementia, such as supporting the elderly to participate in social activities, work which can be achieved by more participation, or professional cognitive training and intelligence-promoting activities, and simultaneously needing auxiliary diet, nutrition and other exercises, and aiming at hopefully slowing down the cognitive decline.

The existing music therapy or light therapy has a certain relieving effect on senile dementia symptoms, but the property characteristics of music and light are not clearly used, the behavior of a patient is observed, the change analysis of specific indexes of the senile dementia patient is lacked, and a treatment mode and special equipment for simultaneous music therapy and phototherapy are not available.

Research finds that based on physiological indexes that Alzheimer's disease patients are closely related to the accumulation of beta amyloid and Tau protein in the brain, the frequency of gamma waves of a cerebral visual cortex (AC) is disturbed, and the like, through analyzing stimulus source characteristics of music and light treatment modes having curative effects on AD patients, the number of beta amyloid is reduced under 40Hz LED light treatment, 40Hz low-frequency sound has better effect and wider range than LED lamps only influencing the cerebral visual cortex under the same frequency, potentials of key areas CA1 and the like influencing the gamma waves in auditory cortex and hippocampus bodies show higher frequency, and the potential is better in cognitive function tests.

Therefore, it is an urgent problem to be solved how to directly eliminate the accumulation of β amyloid and Tau in the brain and correct the gamma wave frequency of the large cerebral visual cortex (AC) in alzheimer's disease patients, thereby physiologically treating and improving the cognitive function of the patients.
