She seems to be trying to remember. Three weeks. What is this? I show her a pencil. A pen. A purse, key, diary and cigar are identified correctly. At lunch she eats cauliflower and pork. Asked what she is eating she answers spinach. When she was chewing meat and asked what she was doing, she answered potatoes and horseradish.

When objects are shown to her, she does not remember after a short time which objects have been shown. When she is asked to write, she holds the book in such a way that one has the impression that she has a loss in the right visual field. Asked to write Auguste D. It is necessary to repeat every word. Amnestic writing disorder. In the evening her spontaneous speech is full of paraphasic derailments and perseverations. The tangles are insoluble aggregates of tau protein.

Plaques known as senile plaques are deposits of another protein, amyloids. Also characteristic of the disease that was named after Alois Alzheimer is the loss atrophy of brain mass. Specifically associated with AD, and probably somehow linked to the plaques and tangles, is the eventual degeneration of these critical areas of the brain:.

Brain Functions. Temporal lobe — speech, memory, hearing. Parietal lobe — sensory integration, spatial sense, navigation. Frontal cortex — involved with, among other things, problem solving, memory, language, judgment, is thought to be the center for our personality.

Damage to areas in the frontal cortex often leads to personality changes. Hippocampus — short term memory, spatial navigation. Cingulate gyrus — emotion formation, memory, learning.

Other symptoms that led to her incarceration at the City Hospital in Frankfurt included:. She eventually lost the ability as well as the incentive to care for herself. Her husband was forced to hospitalize her. 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. 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. Four additional drugs are approved over the next 10 years.

Former U. 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. 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 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.

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.

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. 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.

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.
