Major Milestones in Alzheimer’s and Brain Research


Alzheimer's disease was first described in 1906. In the century since then, scientists have made remarkable strides in understanding how Alzheimer's affects the brain and learning how to make life better for affected individuals and families. Below are some important milestones in our progress, including the founding of the Alzheimer's Association in 1980, which has played a key role in advancing research and raising awareness of the disease. Sign up for our weekly e-news and stay up-to-date on the latest advances in Alzheimer's treatments, care and research.

1906-1960: First discovery


Dr. Alzheimer

1906: Dr. Alois Alzheimer first describes "a peculiar disease"

German physician Alois Alzheimer, a pioneer in linking symptoms to microscopic brain changes, describes the haunting case of Auguste D., a patient who had profound memory loss, unfounded suspicions about her family, and other worsening psychological changes. In her brain at autopsy, he saw dramatic shrinkage and abnormal deposits in and around nerve cells.

Dr. Alzheimer died in 1915, never suspecting that his encounter with Auguste D. would one day touch the lives of millions and ignite a massive international research effort. Scientists recognize Dr. Alzheimer not only for his groundbreaking characterization of a major disease but also as a role model. He set a new standard for understanding neurodegenerative disorders by establishing a close clinical relationship with his patients and using new scientific tools to determine how symptoms related to physical brain changes.

1910

Alzheimer's disease named

 

Emil Kraepelin, a German psychiatrist who worked with Dr. Alzheimer, first names "Alzheimer's Disease" in the eighth edition of his book Psychiatrie.

1931

Invention of electron microscope allows further study of brain

 

In 1931, Germans Max Knoll and Ernst Ruska co-invent the electron microscope, which can magnify up to 1 million times. It is not until after WWII that the electron microscope becomes common in major research settings, enabling scientists to study brain cells in more detail.

1968

Development of cognitive measurement scales

 

Researchers develop the first validated measurement scale for assessing cognitive and functional decline in older adults, paving the way to correlate the level of measured impairment with estimates of the number of brain lesions and the volume of damaged tissue.

1970-1979: Modern Research Era


1974

Founding of National Institute on Aging

 

An act of Congress establishes the National Institute on Aging (NIA) as one of our National Institutes of Health (NIH). The NIA is our primary federal agency supporting Alzheimer's research.

1976

Alzheimer's recognized as most common form of dementia

 

Neurologist Robert Katzman identifies Alzheimer's disease as the most common cause of dementia and a major public health challenge in his editorial published in Archives of Neurology.

1980-1989: Awareness and momentum


Jerome Stone

1980:
Alzheimer's Association founded

In 1979, Jerome H. Stone and representatives from several family support groups met with the National Institute on Aging to explore the value of a national, independent, nonprofit organization to complement and stimulate federal efforts on Alzheimer's disease. That meeting resulted in the 1980 formation of the Alzheimer's Association with Mr. Stone as founding president.

Today, the Alzheimer's Association is the leading voluntary health organization in Alzheimer's care and support and the largest private, nonprofit funder of Alzheimer's research. Since funding its first grant in 1982, the association has awarded in excess of $300 million to more than 2,100 projects, supporting many of the most exciting developments in Alzheimer's research.

1983

Declaration of National Alzheimer's Disease Month

 

Awareness of Alzheimer's disease increases, leading Congress to designate November 1983 as the first National Alzheimer's Disease Month.

1984

Beta-amyloid identified

 

Researchers George Glenner and Cai'ne Wong report identification of "a novel cerebrovascular amyloid protein," known as beta-amyloid — the chief component of Alzheimer's brain plaques and a prime suspect in triggering nerve cell damage.

1984

Nationwide infrastructure for Alzheimer's research established

 

The NIA begins funding its network of Alzheimer's Disease Centers at flagship medical institutions, establishing a nationwide infrastructure for research, diagnosis and treatment.

1986

1986 Tau protein identified

 

Researchers discover that tau protein is a key component of tangles—the second pathological hallmark of Alzheimer's disease and another prime suspect in nerve cell degeneration.

1987

First Alzheimer's drug trial

 

The Alzheimer's Association assists the NIA and Warner-Lambert Pharmaceutical Company (now Pfizer) in launching and recruiting participants for clinical trials of tacrine, the first drug specifically targeting symptoms of Alzheimer's disease.

1987

First deterministic Alzheimer's gene identified

 

Researchers identify the first gene associated with rare, inherited forms of Alzheimer's disease. This gene on chromosome 21 codes amyloid precursor protein (APP), the parent molecule from which beta-amyloid is formed. Chromosome 21 is also the chromosome of which those with Down syndrome have three copies rather than two. Many individuals with Down syndrome develop Alzheimer's disease, often as young as their 30s and 40s.

1990-1999: Treatments emerge


1991

Federal clinical study consortium launched

 

The National Institute on Aging (NIA) established the Alzheimer's Disease Cooperative Study (ADCS), a nationwide medical network to facilitate clinical research and conduct federally funded clinical trials.

1993

First Alzheimer's risk factor gene identified

 

Researchers identify APOE-e4, a form of the apolipoprotein-E (APOE) gene on chromosome 19, as the first gene that raises risk for Alzheimer's but does not determine that a person who has it will develop the disease.

1993

First Alzheimer's drug approved by FDA

 

The Food and Drug Administration (FDA) approves tacrine (Cognex) as the first drug specifically targeting Alzheimer's memory and thinking symptoms. Four additional drugs are approved over the next 10 years.

Ronald Reagan

1994: President Reagan's diagnosis announced

Former U.S. President Ronald Reagan shares with the American people that he has been diagnosed with Alzheimer's disease.

In an open letter to the American people about his decision to share his diagnosis President Reagan wrote, "In opening our hearts, we hope this might promote greater awareness of this condition. Perhaps it will encourage a clearer understanding of the individuals and families who are affected by it."

1994

First World Alzheimer's Day

 

The first World Alzheimer's Day (WAD) launches on September 21 by Alzheimer's Disease International, the umbrella organization of Alzheimer's associations.

1995

First transgenic mouse model announced

 

Researchers announce the first transgenic mouse model that developed Alzheimer-like brain pathology. The mouse was developed by inserting one of the human APP genes linked to a rare, inherited form of Alzheimer's disease.

The Alzheimer's Association first awarded a grant to develop a mouse model of a rare neurodegenerative disorder called Gerstmann-Sträussler-Scheinker syndrome in 1989, laying the technical foundation for Alzheimer's mouse models.

1999

"Alzheimer's vaccine" successful in mice

 

The first in a series of reports is published showing that injecting transgenic "Alzheimer" mice with beta-amyloid prevents the animals from developing plaques and other Alzheimer-like brain changes.

2000-2009: Progress and hope


2003

National Alzheimer's Disease
Genetics Study begins

 

The Alzheimer's Association partners with the National Institute on Aging to recruit participants for the National Alzheimer's Disease Genetics Study, a federal initiative to collect and bank blood samples from families with several members who developed Alzheimer's disease late in life in order to identify additional Alzheimer's risk genes.

2004

First report on Pittsburgh Compound B (PIB)

 

Researchers at the Alzheimer's Association International Conference on Alzheimer's Disease (AAICAD) share their first report on an imaging agent called Pittsburgh Compound B (PIB), a major potential breakthrough in disease monitoring and early detection. PIB enters the brain through the bloodstream and attaches itself to beta-amyloid deposits, where it can be detected by positron emission tomography (PET).

The Alzheimer's Association provided significant support to initiatives to develop PIB and conduct preclinical testing it in animal studies.

ADNI map

2004: Alzheimer's Disease
Neuroimaging Initiative (ADNI)

The Alzheimer's Association joins public and private donors as a major sponsor of the Alzheimer's Disease Neuroimaging Initiative (ADNI), a nationwide study to establish standards for obtaining and interpreting brain images.

The ultimate goal of ADNI is to determine whether standardized images, possibly combined with laboratory and psychological tests, can identify high-risk individuals; provide early detection; and track and monitor treatment effects, especially in clinical trials of disease-modifying drugs. In 2006, the Association launched the European Alzheimer's Disease Neuroimaging Initiative (E-ADNI), to expand ADNI's scope by combining data from several European brain imaging initiatives with ADNI data. This effort has now grown into World Wide ADNI (WW-ADNI), a global network of flagship research sites united in a common effort to improve diagnosis and speed treatment development with standardized protocols and data shared internationally.

2005
