Alzheimer dementia: can be prevented before symptoms start?

Alzheimer disease (AD) is a neurodegenerative disease. It is the most common cause of dementia. Its symptoms start to appear after many years of asymptomatic pathophysiology of the brain’s neural cells. In 2012, the National Institute on Aging (NIA) and the Alzheimer’s Association established a new guideline that classified Alzheimer disease (AD) into three stages, which are pre-clinical stage, mild cognitive impairment (MCI) stage and lastly dementia due to AD. Since that time until 2017, most of the Alzheimer’s researches were focusing on how the disease can be diagnosed in pre-clinical stage. There are many benefits behind the early diagnosis of AD, especially if we know there is no cure for the disease until now. Early diagnosis can be decelerating the progression of the disease, through early intervention with medication and applying the protective value. As many neurosciences’ physicians believed, future planning to deal with AD depended mostly on early diagnosis to preserve brain function.
