Objectives
Narrative objectives1
The number of patients with dementia is increasing sharply toward the super-aging society. Among them, there are various methods such as brain MRI examination and SPECT examination for early diagnosis of Alzheimer's dementia. But the highest sensitivity and specificity are the highest in amyloid beta protein 1-42 in the cerebrospinal fluid, tau protein, and phosphorylated tau protein. In addition, recent studies have shown that blood and cerebrospinal fluid have increased amyloid beta protein oligomers. In recent years, in Dementia with Lewy bodies, alpha-synuclein level has been decreased, and it has been reported to be correlated with severity. Therefore, it can be said that these amyloid beta protein, tau protein, and alpha-synuclein have established biomarker status, but except for phosphorylated tau in cerebrospinal fluid, these tests are not covered by insurance. In recent years, development of anti-dementia drugs has progressed, and the importance of early diagnosis and early treatment has been emphasized. Detailed neurological examination, a cognitive function test by a clinical psychologist, a brain MRI scan, and a SPECT are performed, and then cerebrospinal fluid/blood amyloid beta protein, tau protein, and alpha synuclein are examined, and a clinical diagnosis is made. Thus, this study is considered to be extremely interesting in considering the pathogenic mechanism of dementia including Alzheimer's dementia.
