As a result of this study, patients with Alzheimer''s disease were also able to return to normal life when Dapson stopped inflammation and protected brain cells. These findings suggest that the cause of dementia syndrome, including Alzheimer''s disease, is an inflammatory response. When diagnosing Alzheimer''s disease, it is proposed to determine the diagnosis and treatment of Alzheimer''s disease based on whether the inflammatory response persists or whether the inflammatory response is being treated as the main cause of inflammation in brain cells. Among the cognitive function tests, it is necessary to examine whether the patient has returned to daily life in the NPI-Q and K-IADL items, and determine whether there is a cognitive impairment. The inflammatory response is amplified by several causes in brain cells and the cells are attacked by hypochlorites. Various foreign substances accumulate within the cells and kill brain cells. Here, dapsone was used as a preventive substance to stop the death of neurons. In the mouse experiments, but the neurons damaged by a transient ischemic disease of the brain blood flow was restored after a study reported that the administration dapson 16. Therefore, this study proposes to determine the diagnosis and treatment of Alzheimer''s disease based on whether the inflammatory response persists or whether the inflammatory response is being treated as the main cause of inflammation in brain cells when diagnosing Alzheimer''s disease. In various studies on the effects of NSAID and mild cognitive impairment and Alzheimer''s disease, there have been reports that most epidemiological studies are not effective 17 . However, if the diagnosis of Alzheimer''s disease is evaluated based on inflammation in brain cells, the results of epidemiological studies will be very different. Among the tests for determining the presence or absence of cognitive impairment in this study, the criteria for the cognitive function test of the epidemiological s
