There is a lot to consider before genetic testing. Although these tests can provide important information about health risk, they can also raise worries by learning about genetic risks for these diseases. These tests also have certain limitations assessing genetic risk information based on specific genetic variants.
Personal health behaviors and family health history should all be taken into account on decision about whether to have a genetic test. Talk to your healthcare provider or search for a genetic counselor near you by visit website of the National Society of Genetic Counselors (http://www.aboutgeneticcounselors.com).
In some cases, the laboratory may not be able to process you sample. If this happens, we will notify you by email or private message and provide you with one free replacement kit. Other companies offering genetic risk tests may include different variants for the same health condition. This means that it's possible to get different results using a test from a different company.
Some reports are about diseases that may not be effectively treated or cured at present. Others may have effective treatment or prevention options, but these actions may carry their own health risks. If you feel anxious or have diagnosed with anxiety or depression, you may be upset by learning genetic risks for these diseases, and about genetic risks for family members who share DNA.
Alzheimer's disease, also known as dementia, is the most common type of senile dementia, accounting for 50% of all senile dementia cases. It occurs in the elderly and pre-elderly as progressive cognitive dysfunction and behavioral impairment characterized by degenerative lesions in the central nervous system. Clinically, the disease manifests as memory impairment, aphasia, apraxia, agnosia, visuospatial impairment, damage to abstract thinking and computational power, personality and behavioral changes, etc.
Late-onset Alzheimer's disease develops over age 65.
There is currently no cure for this condition.
Psychopathological symptoms controlling or medication may be used to delay or ease symptoms.
The APOE ε4 variant and the risk estimates are mainly based on people of European descent.
