(Seoul = Yonhap News) Correspondent Han Seong-gan = The Alzheimer’s Association (AA) and the National Institute on Aging (NIA) have decided to classify Alzheimer’s dementia into seven stages according to the patient’s cognitive function and physiological changes. .
AA and NIA are grading dementia according to the severity of symptoms, such as mild, moderate, and severe, as the use of test methods that can detect abnormal proteins in two brain neurons, such as beta-amyloid plaques and tautangle, known to cause Alzheimer’s dementia, has increased. Archyde.com reported on the 18th that the 2018 guidelines for grading were changed to be subdivided into 7 levels.
Dr. Clifford Jack, a dementia radiologist at the Mayo Clinic who was involved in the new staged classification of dementia, is… Classifying cancer into 7 stages is ‘1, 2, 3…’. ’ He explained that it was no different from dividing by disease.
Dementia grades are divided into stages 1 to 7 according to the degree of change in specific biomarkers and cognitive function according to the stage of dementia progression, and each stage is further subdivided into grades a, b, c, and d.
For example, stage 1a grade (1a) is the first grade at which evidence of dementia begins to appear.
Stage 0 was also added as a stage before stage 1.
This includes people with dementia risk mutations, who are highly likely to develop dementia, and patients with Down syndrome, who show symptoms of dementia in 75% of adults.
This new dementia grading system will go through public hearings to listen to experts’ opinions and make necessary modifications.
Dr. Maria Carrillo, chief scientific officer of the Alzheimer’s Association, said that as we understand that certain biomarkers appear at different stages of dementia, we are entering an era of personalized treatment for each stage of dementia.
The new dementia grading system was presented at the International Conference of the Alzheimer’s Association in Amsterdam, Netherlands.
Symptoms by stage are as follows:
<1기> Cognitive function appears normal, but pathological changes appear in the brain.
<2기> Mild cognitive impairment appears. It is usually difficult to distinguish from forgetfulness.
<3기> mild cognitive impairment (MCI). Getting lost or not finding the right words.
<4기> moderate dementia. Poor short-term memory and unable to remember parts of one’s past.
<5기> Cognitive function continues to decline, requiring help from others to perform daily activities.
<6기> severe dementia. It requires constant monitoring and care. He cannot remember most of his family and friends and his personality changes.
<7기> death is drawing near Motor skills are impaired and communication is impossible. I can’t cover the toilet and I have to feed rice.
