Japanese study finds 'alternative' Alzheimer's disease

many medical researchers believe that the cause of Alzheimer's(
also known as early-onset dementia) is beta amyloid protein builds up in the brain, forming a color plaque known as the "older spot." But Japanese researchers have found that a small number of people without "older spots" in the brain can also develop Alzheimer's diseaseAccording to Japanese media27 reported,medical theory pointed out that,beta amyloid fibrosis and precipitation to form a "age spot",can cause nerve cells to die,cause Alzheimer's diseasefound similar mutations in the genes that encode the synthetic beta amyloid in several Alzheimer's patients in Japan, and their brains do not produce "older plaques" until they become ill,
said Yumi Toyama, an associate professor at Osaka City University, and othersAt the same time, beta amyloid proteins in their brains are more likely to form low-polymers with smaller molecular weights, which also appear to be linked to Alzheimer's disease Previous animal studies have also shown that in the stagewhere where only a few beta amyloid molecules are combined before the formation of the "age spot", nerve cell activity in animals is also hampered, with some of the symptoms of Alzheimer's disease such as memory impairment Based on this, the researchers speculate that some of the causes of Alzheimer's disease may be more closely related to beta amyloid molecules that occur and precipitate, and that the development of new methods to detect oligomers formed by such protein molecules will help identify "alternative" Alzheimer's disease as early as possible
