There is no standard for how long you typically live with age-related brain changes. This imaging historical description has nothing to do with the disease itself, has no therapeutic implications, and has no direct connection to life expectancy.
Age-related brain changes is a kind of imaging description of the brain, such as CT, MRI when, often under the imaging can see a slight brain atrophy, ventricular enlargement, and can be accompanied by a smaller area of ischemic foci, small soft foci or lacunar infarction.
Geriatric brain changes is the imaging description can not represent the severity of the disease, if only simple geriatric brain changes, no combination of other diseases, generally better prognosis does not affect, do not directly affect the life expectancy.
However, senile brain changes are often a warning that the patient has already experienced aging of the brain structure, and should be taken seriously to prevent cerebrovascular disease as well as to prevent all kinds of cognitive and motor sensory deficits in old age, and need to strengthen the follow-up or improve other examinations.
