Timeline of Alzheimer's disease

This is a timeline of Alzheimer's disease, describing especially major discoveries, developments and organizations concerning the disease.

Big picture

Year/period

Key developments

Prior to 1890s

Early in History, Solon (638 BC–558 BC) relates alteration in judgment to aging. Plato notes that very old age can have influence on madness.

1890s–1960s

Period of discovery of Alzheimer's disease, starting virtually with the pioneer work by Alois Alzheimer, until the recognition of the disease in the 1960s.

1970s

Alzheimer's disease is recognized as the most common form of dementia.

1980s

The organic constituents of the two characteristic damages of Alzheimer's disease are identified: Beta-amyloid and Tau protein. Many organizations focused on Alzheimer's disease start to be founded across the world.

1990s

Several genes responsible for the inherited transmission of Alzheimer's disease are identified: PSEN1, PSEN2 and Apolipoprotein E-e4. The first vaccine is used in mice.

2000s–present

At present, there's no cure for Alzheimer's disease. Incidence is higher in developed countries, which correlates with the proportion of senior citizens.

1892

Discovery

French pathologist Paul Blocq and Romanian neurologist Gheorghe Marinescu observe senile plaques for the first time.

1898

1906

Discovery

At the 37th annual conference of German psychiatrists, physician Alois Alzheimer describes the case of patient Auguste Deter, who had profound memory loss, unfounded suspicions about her family, and other worsening psychological changes.
