9 hours ago The age-adjusted annual death rate increased from 0.4 per 100,000 persons in 1979 to 4.2 per 100,000 persons in 1987 (Figure 1). For men, the annual rate increased from 0.5 to 4.6 per 100,000, and for women, from 0.3 to 3.9 per 100,000. For blacks and whites, rates increased with age; … >> Go To The Portal
During the 1980s our field began its foundational studies of profiling the neuropsychological deficits associated with AD and its differentiation from other dementias (e.g., cortical vs. subcortical dementias). The 1990s continued these efforts and began to identify the specific cognitive mechanisms affected by various neuropathologic substrates.
As discussed in the Overview (page 4), under the 1984 diagnostic guidelines, only individuals with symptoms such as significant problems with learning, thinking or memory could receive a diagnosis of Alzheimer’s disease.
This observation suggests that, in some cases, “AD dementia” appears only following the addition of other pathologies to a sub-threshold level of AD pathology. Such pathological heterogeneity leads to neuropsychological heterogeneity, making dementia characterization and differential diagnosis more difficult.

Auguste Deter was the first person officially diagnosed with Alzheimer's disease. Born in 1850, Deter first started showing signs of the disease when she was only in her early 50s.
Alzheimer's disease is the most common cause of dementia. In this report, Alzheimer's dementia refers to dementia that is caused by, or believed to be caused by, the brain changes of Alzheimer's disease. Alzheimer's disease is the most common cause of dementia, accounting for an estimated 60% to 80% of cases.
Although some studies have shown an association between certain modifiable lifestyle factors and a reduced risk for Alzheimer disease, the National Institutes of Health says that age is the strongest known risk factor where most people receive the diagnosis after age 60.
The state with the highest rate of Alzheimer's is Alaska. Cases of the disease are projected to increase from 7,100 in 2017 to 11,000 in 2025 — an increase of 54.9 percent, reports AA. Why are rates so high there? It's most likely due to the projected growth of Alaska's elderly population.
7 Early Signs of Alzheimer's DiseaseMemory loss that affects daily life. ... Loss of problem-solving ability. ... Confusion about times and places. ... Limitations with language. ... Misplacing things. ... Poor judgement. ... Personality changes.
Alzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells. One of the proteins involved is called amyloid, deposits of which form plaques around brain cells. The other protein is called tau, deposits of which form tangles within brain cells.

Alzheimer's disease and dementia are most common in Western Europe (with North America close behind) and least common in Sub-Saharan Africa. African-Americans are about twice as likely to have Alzheimer's disease or other forms of dementia as whites.
Women are disproportionately affected by Alzheimer's disease (AD). Nearly two-thirds of the more than 5 million Americans living with Alzheimer's are women and two-thirds of the more than 15 million Americans providing care and support for someone with Alzheimer's disease are women.
New research finds that it's not only what you eat, but also how you combine certain foods that can increase your risk of developing Alzheimer's and other forms of dementia in later life. The foods most strongly associated with this risk were sugary snacks, alcohol, processed meats, and starches like potatoes.
New research has shown that sugary drink intake is associated with an increased risk of Alzheimer's disease. Research presented at Alzheimer's Association International Conference today has shown that sugary drink intake is associated with an increased risk of Alzheimer's disease.
2. Japanese Studies. Among developed countries, Japan seems to have the lowest prevalence of dementia in general and Alzheimer's disease in particular.
This led to greater attention to the disease by the public and at the National Institutes of Health, which established the National Alzheimer’s Disease Research Center program to study the cause, neuropathology, and clinical characteristics of AD.
The new criteria for dementia and AD adopted in the 1980s improved the reliability of the clinical diagnosis and allowed group studies of mildly demented patients to be carried out with a reasonable degree of accuracy.
Several investigators refined the ability to detect and measure cerebrospinal fluid levels of Aβ (the main constituent of the plaque) and tau protein (a constituent of the neurofibrillary tangle) that were indicative of AD pathology in the brain. Klunk and colleagues (see Mathis et al., 2003) developed Pittsburgh compound-B ( [ 11 C]-PIB), an agent that binds to Aβ, for use with PET imaging to reveal deposition of amyloid in the brain. Tau-binding agents that can be used with PET imaging have also been recently developed (for review, see Brosch, Farlow, Risacher, & Apostolova, 2017 ).
One of the great challenges faced by neuropsychologists over the past 50 years is to understand the cognitive and behavioral manifestations of dementia and their relationship to underlying brain pathology. This challenge has grown substantially over the years with the aging of the population and the age-related nature of many dementia-producing neurodegenerative diseases. Although the concept of dementia has existed for thousands of years ( Mahandra, 1984 ), it is only early in the past century that the essential clinical syndrome and associated neurodegenerative changes were first discovered. In 1907, Aloysius “Alöis” Alzheimer carefully described the symptoms of a 51-year-old woman, Auguste Deter, who was under his care at the state asylum in Frankfurt Germany ( Alzheimer, 1907; for an English translation, see Stelzmann et al., 1995) ( Figure 1 ). Alzheimer’s description of her symptoms is almost certainly the first neuropsychological characterization of the disease:
Specifically, DSM-II defined “organic brain syndrome” as a “basic mental condition characteristically resulting from diffuse impairment of brain tissue function from whatever cause,” and which is manifested behaviorally as impairment in orientation, memory, intellectual functions, judgment, and affect ( APA, 1968 ).
Neuropsychology has played a critical role in characterizing the cognitive changes associated with AD and related dementing disorders. This has improved the ability to accurately diagnose AD and differentiate it from other dementing disorders, to identify subtle cognitive changes that occur in the preclinical/prodromal phase of disease , and to track progression of the disease over the aging-MCI-AD continuum. Recent advances in AD biomarker development will alter this role. Increasingly, diagnosticians and investigators will be asked to use an array of available biomarkers to identify the neuropathologic determinants underlying cognitive changes within a given individual, and to detect neuropathology in its earliest stages before the onset of significant cognitive change.
Although dementia has been described in ancient texts over many centuries (e.g., “Be kind to your father, even if his mind fail him.”. – Old Testament: Sirach 3:12), our knowledge of its underlying causes is little more than a century old. Alzheimer published his now famous case study only 110 years ago, and our modern understanding ...
The patient was referred to our specialty memory clinic at the age of 58 with a 2-year history of repetitiveness, memory loss, and executive function loss. Magnetic resonance imaging scan at age 58 revealed mild generalized cortical atrophy. She is white with 2 years of postsecondary education.
β-amyloid (Aβ) is a 38 to 43 amino acid peptide that aggregates in AD forming toxic soluble oligomers and insoluble amyloid fibrils which form plaques.
Whose Quality of Life Is It Anyway?: The Validity and Reliability of the Quality of Life-Alzheimer's Disease (QoL-AD) Scale
As a result, what was “Alzheimer’s disease” under the 1984 guidelines is called “dementia due to Alzheimer’s” or “Alzheimer’s dementia ” under the 2011 guidelines — one stage in the continuum of the disease. This edition of Alzheimer’s Disease Facts and Figures. reflects this change in understanding and terminology.
A8The number of new cases of Alzheimer’s increases dramatically with age: in 2018, there will be approximately 66,000 new cases among people age 65 to 74, 173,000 new cases among people age 75 to 84, and 245,000 new cases among people age 85 and older .
The three primary reasons caregivers provide care and assistance to a person with Alzheimer’s are (1) the desire to keep a family member or friend at home (65 percent), (2) proximity to the person with dementia (48 percent) and (3) the caregiver’s perceived obligation as a spouse or partner (38 percent).
These changes are eventually accompanied by the damage and death of neurons. Vascular dementia. The brain changes of vascular dementia are found in about 40 percent of brains from individuals with dementia.4-5About 10 percent of brains from individuals with dementia show evidence of vascular dementia alone.
A specific form called variant Creutzfeldt-Jakob disease is believed to be caused by consumption of products from cattle affected by mad cow disease. Normal pressure hydrocephalus.
In PD, alpha-synuclein aggregates appear in an area deep in the brain called the substantia nigra. The aggregates are thought to cause degeneration of the nerve cells that produce dopamine.
