Early Onset versus Late Onset

Early-onset Alzheimer's disease occurs when the disease is present in people who are under the age of 60. It is a very rare disorder in comparison with the more typical late-onset Alzheimer's disease where onset occurs at or after 60 years of age. Early-onset Alzheimer's disease more often has a single gene cause. Due to this, identification of early-onset Alzheimer's disease has been important in understanding how Alzheimer's disease works in general. That is to say, that even though it is a rare disorder, the abnormalities in proteins that are seen in early-onset Alzheimer's disease are very similar to those seen in late-onset Alzheimer's disease. Studying these protein abnormalities in early-onset Alzheimer's disease has given insight into how the genes give rise to the abnormal proteins. Early-onset Alzheimer's disease is more commonly inherited than late-onset Alzheimer's disease. In most other ways, the two are difficult to tell apart.
