Time to Alzheimer's disease diagnosis in Japan: a retrospective observational study
In Japan, the time from symptom onset to diagnosis takes approximately 2.2 years. The time after symptom onset to reach the initial medical contact consumes the longest time; hence, minimizing this time could shorten the overall diagnostic duration. Since early diagnosis facilitates timely treatment of AD, it is important to raise awareness of the disease and the need for early consultation.
