This loss results in gross atrophy of the affected regions, including degeneration in the temporal lobe and parietal lobeand parts of the frontal cortex and cingulate gyrus. Tangles neurofibrillary tangles are aggregates of the microtubule-associated protein tau which has become hyperphosphorylated and accumulate inside the cells themselves.
Although many older individuals develop some plaques and tangles as a consequence of aging, the brains of people with Alzheimer's disease have a greater number of them in specific brain regions such as the temporal lobe. Alzheimer's disease has been identified as a protein misfolding diseasea proteopathycaused by the accumulation of abnormally folded amyloid beta protein into amyloid plaques, and tau protein into neurofibrillary tangles in the brain.
Amyloid beta is a fragment from the larger amyloid-beta precursor protein APP a transmembrane protein that penetrates the neuron's membrane. APP is critical to neuron growth, survival, and post-injury repair.
Alzheimer's disease is also considered a tauopathy due to abnormal aggregation of the tau protein. Every neuron has a cytoskeletonan internal support structure partly made up of structures called microtubules.
These microtubules act like tracks, guiding nutrients and molecules from the body of the cell to the ends of the axon and back. A protein called tau stabilises the microtubules when phosphorylatedand is therefore called a microtubule-associated protein. In Alzheimer's disease, tau undergoes chemical changes, becoming hyperphosphorylated ; it then begins to pair with other threads, creating neurofibrillary tangles and disintegrating the neuron's transport system.
Exactly how disturbances of production and aggregation of the beta-amyloid peptide give rise to the pathology of Alzheimer's disease is not known. Accumulation of aggregated amyloid fibrilswhich are believed to be the toxic form of the protein responsible for disrupting the cell's calcium ion homeostasisinduces programmed cell death apoptosis. Various inflammatory processes and cytokines may also have a role in the pathology of Alzheimer's disease. Inflammation is a general marker of tissue damage in any disease, and may be either secondary to tissue damage in Alzheimer's disease or a marker of an immunological response.
Obesity and systemic inflammation may interfere with immunological processes which promote disease progression. Alterations in the distribution of different neurotrophic factors and in the expression of their receptors such as the brain-derived neurotrophic factor BDNF have been described in Alzheimer's disease.
Alzheimer's disease is usually diagnosed based on the person's medical historyhistory from relatives, and behavioral observations. The presence of characteristic neurological and neuropsychological features and the absence of alternative conditions is supportive. Assessment of intellectual functioning including memory testing can further characterise the state of the disease.
The diagnosis can be confirmed with very high accuracy post-mortem when brain material is available and can be examined histologically. A histopathologic confirmation including a microscopic examination of brain tissue is required for a definitive diagnosis. Good statistical reliability and validity have been shown between the diagnostic criteria and definitive histopathological confirmation. Neuropsychological tests including cognitive tests such as the Mini—Mental State Examination MMSE are widely used to evaluate the cognitive impairments needed for diagnosis.
More comprehensive test arrays are necessary for high reliability of results, particularly in the earliest stages of the disease. Further neurological examinations are crucial in the differential diagnosis of Alzheimer's disease and other diseases.
Caregivers can supply important information on the daily living abilities, as well as on the decrease, over time, of the person's mental function. Supplemental testing provides extra information on some features of the Album) or is used to rule out other diagnoses. Blood tests can identify other causes for dementia than AD  —causes which may, in rare cases, be reversible. It is also necessary to rule out delirium. Psychological tests for depression are employed, since depression can either be concurrent with Alzheimer's disease see Depression of Alzheimer diseasean early sign of cognitive impairment,  or even the cause.
Due to low accuracy, the C-PIB-PET scan is not recommended to be used as an early diagnostic tool or for predicting the development of Alzheimer's disease when people show signs of mild cognitive impairment MCI.
There is no evidence that supports any particular measure as being effective in preventing Alzheimer's disease. Epidemiological studies have proposed relationships between certain modifiable factors, such as diet, cardiovascular risk, pharmaceutical products, or intellectual activities, among others, and a population's likelihood of developing Alzheimer's Album). Only further research, including clinical trials, will reveal whether these factors can help to prevent Alzheimer's disease.
Cardiovascular risk factors, such as hypercholesterolaemiahypertensiondiabetesand smokingare associated with a higher risk of onset and worsened course of Alzheimer's disease. Long-term usage of non-steroidal anti-inflammatory drugs NSAIDs were thought in to be associated with a reduced likelihood of developing Alzheimer's disease. Evidence suggests that higher education and occupational attainment, and participation in leisure activities show a reduced risk of developing Alzheimer's,  or of delaying the onset of symptoms.
This is compatible with the cognitive reserve theory, which states that some life experiences result in more efficient neural functioning providing the individual a cognitive reserve that delays the onset of dementia manifestations. Physical exercise is associated with decreased rate of dementia. Diet is seen to be a modifiable risk factor for the development of dementia. A different approach has been to incorporate elements of both of these diets into one known as the MIND diet.
Raised blood sugar levels over a long time, can damage nerves and cause memory problems if they are not managed. The MIND diet may be more protective but further studies are needed. The Mediterranean diet seems to be more protective against Alzheimer's than DASH but there are no consistent findings against dementia in general. The role of olive oil needs further study as it may be one of the most important components in reducing the risk of cognitive decline and dementia.
In those with celiac disease or non-celiac gluten sensitivitya strict gluten-free diet may relieve the symptoms given a mild cognitive impairment. Conclusions on dietary components have been difficult to ascertain as results have differed between population-based studies and randomised controlled trials.
Curcumin as of [update] had not shown benefit in people even though there is tentative evidence in animals. However, further population studies are recommended to see this use beyond experimental. There is no cure for Alzheimer's disease; available treatments offer relatively small symptomatic benefits but remain palliative in nature.
Current treatments can be divided into pharmaceutical, psychosocial, and caregiving. Medications used to treat the cognitive problems of Alzheimer's disease include: four acetylcholinesterase inhibitors tacrinerivastigminegalantamineand donepezil and memantinean NMDA receptor antagonist.
The benefit from their use is small. Reduction in the activity of the cholinergic neurons is a well-known feature of Alzheimer's disease. Glutamate is an excitatory neurotransmitter of the nervous systemalthough excessive amounts in the brain can lead to cell death through a process called excitotoxicity which consists of the overstimulation of glutamate receptors.
Excitotoxicity occurs not only in Alzheimer's disease, but also in other neurological diseases such as Parkinson's disease and multiple sclerosis. It acts on the glutamatergic system by blocking NMDA receptors and inhibiting their overstimulation by glutamate. An extract of Ginkgo biloba known as EGb has been widely used for treating Alzheimer's and other neuropsychiatric disorders.
EGb is the only one that showed improvement of symptoms in both Alzheimer's disease and vascular dementia. EGb is seen as being able to play an important role either on its own or as an add-on particularly when other therapies prove ineffective.
Many studies of its use in mild to moderate dementia have shown it to significantly improve cognitive function, activities of daily living, and neuropsychiatric symptoms. However, its use has not been shown to prevent the progression to dementia. Atypical antipsychotics are modestly useful in reducing aggression and psychosis in people with Alzheimer's disease, but their advantages are offset by serious adverse effects, such as strokemovement difficulties or cognitive decline.
Psychosocial interventions are used as an adjunct to pharmaceutical treatment and can be classified within behavior- emotion- cognition- or stimulation-oriented approaches. Research on efficacy is unavailable and rarely specific to Alzheimer's disease, focusing instead on dementia in general. Behavioral interventions attempt to identify and reduce the antecedents and consequences of problem behaviors.
This approach has not shown success in improving overall functioning,  but can help to reduce some specific problem behaviors, such as incontinence. Emotion-oriented interventions include reminiscence therapyvalidation therapysupportive psychotherapysensory integrationalso called snoezelenand simulated presence therapy. A Cochrane review has found no evidence that this is effective.
A review of the effectiveness of RT found that effects were inconsistent, small in size and of doubtful clinical significance, and varied by setting. There is partial evidence indicating that SPT may reduce challenging behaviors. There is no evidence to support the usefulness of these therapies.
The aim of cognition-oriented treatments, which include reality orientation and cognitive retrainingis the reduction of cognitive deficits. Reality orientation consists of the presentation of information about time, place, or person to ease the understanding of the person about its surroundings and his or her place in them.
On the other hand, cognitive retraining tries to improve impaired capacities by exercising mental abilities. Both have shown some efficacy improving cognitive capacities,  although in some studies these effects were transient and negative effects, such as frustration, have also been reported.
Stimulation-oriented treatments include artmusic and pet therapies, exerciseand any other kind of recreational activities. Stimulation has modest support for improving behavior, mood, and, to a lesser extent, function. Nevertheless, as important as these effects are, the main support for the use of stimulation therapies is the change in the person's routine.
Since Alzheimer's has no cure and it gradually renders people incapable of tending to their own needs, caregiving is essentially the treatment and must be carefully managed over the course of the disease. During the early and moderate stages, modifications to the living environment and lifestyle can increase patient safety and reduce caretaker burden. In such cases, the medical efficacy and ethics of continuing feeding is an important consideration of the caregivers and family members.
As the disease progresses, different medical issues can appear, such as oral and dental diseasepressure ulcersmalnutritionhygiene problems, or respiratoryskinor eye infections. Careful management can prevent them, while professional treatment is needed when they do arise. The early stages of Alzheimer's disease are difficult to diagnose.
A definitive diagnosis is usually made once cognitive impairment compromises daily living activities, although the person may still be living independently. The symptoms will progress from mild cognitive problems, such as memory loss through increasing stages of cognitive and non-cognitive disturbances, eliminating any possibility of independent living, especially in the late stages of the disease. Life expectancy of people with Alzheimer's disease is reduced. Other coincident diseases such as heart problemsdiabetes or history of alcohol abuse are also related with shortened survival.
Pneumonia and dehydration are the most frequent immediate causes of death brought by Alzheimer's disease, while cancer is a less frequent cause of death than in the general population. Two main measures are used in epidemiological studies: incidence and prevalence. Incidence is the number of new cases per unit of person-time at risk usually number of new cases per thousand person-years ; while prevalence is the total number of cases of the disease in the population at any given time.
Regarding incidence, cohort longitudinal studies studies where a disease-free population is followed over the years provide rates between 10 and 15 per thousand person-years for all dementias and 5—8 for Alzheimer's disease,   which means that half of new dementia cases each year are Alzheimer's disease. Advancing age is a primary risk factor for the disease and incidence rates are not equal for all ages: every five years after the age of 65, the risk of acquiring the disease approximately doubles, increasing from 3 to as much as 69 per thousand person years.
The prevalence of Alzheimer's disease in populations is dependent upon different factors including incidence and survival. Since the incidence of Alzheimer's disease increases with age, it is particularly important to include the mean age of the population of interest.
In the United States, Alzheimer's prevalence was estimated to be 1. The ancient Greek and Roman philosophers and physicians associated old age with increasing dementia. He followed her case until she died in when he first reported publicly on it.
For most of the 20th century, the diagnosis of Alzheimer's disease was reserved for individuals between the ages of 45 and 65 who developed symptoms of dementia. The terminology changed after when a conference on Alzheimer's disease concluded that the clinical and pathological manifestations of presenile and senile dementia were almost identical, although the authors also added that this did not rule out the possibility that they had different causes.
Eventually, the term Alzheimer's disease was formally adopted in medical nomenclature to describe individuals of all ages with a characteristic common symptom pattern, disease course, and neuropathology. Dementia, and specifically Alzheimer's disease, may be among the most costly diseases for society in Europe and the United States,   while their costs in other countries such as Argentina,  and South Korea,  are also high and rising. These costs will probably increase with the aging of society, becoming an important social problem.
AD-associated costs include direct medical costs such as nursing home caredirect nonmedical costs such as in-home day careand indirect costs such as lost productivity of both patient and caregiver.
Costs increase with dementia severity and the presence of behavioral disturbances,  and are related to the increased caregiving time required for the provision of physical care. Economic evaluations of current treatments have shown positive results.
The role of the main caregiver is often taken by the spouse or a close relative. Dementia caregivers are subject to high rates of physical and mental disorders. Cognitive behavioral therapy and the teaching of coping strategies either individually or in group have demonstrated their efficacy in improving caregivers' psychological health.

In earlya trial of verubecestatwhich inhibits the beta-secretase protein responsible for creating beta-amyloid protein was discontinued as an independent panel found "virtually no chance of finding a positive clinical effect". It has a marked increase in oxidative stress in the brain. Medications that reduce oxidative stress have been shown to improve memory.
This process begets increased amyloid-beta, which further damages mitochondria. Research on the effects of meditation on preserving memory and cognitive functions is at an early stage. The ketogenic diet is a very high-fat, adequate-protein, low-carbohydrate diet that is used to treat refractory epilepsy in children. Designed to mimic some of the effects of fasting, following a ketogenic diet leads to elevated blood levels of molecules called ketone bodies : a metabolic state known as ketosis.
These ketone bodies have a neuroprotective effect on aging brain cells, though it is not fully understood why. Limited research in the form of preclinical trials mice and ratsand small-scale clinical human trials, have explored its potential as a therapy for neurodegenerative disorders like Alzheimer's disease.

ISSN Seniors with dementia experience the same prevalence of conditions likely to cause pain as seniors without dementia. Persistent pain can lead to decreased ambulation, depressed mood, sleep disturbances, impaired appetite, and exacerbation of cognitive impairment  and pain-related interference with activity is a factor contributing to falls in the elderly.
Although persistent pain in people with dementia is difficult to communicate, diagnose, and treat, failure to address persistent pain has profound functional, psychosocial and quality of life implications for this vulnerable population. Health professionals often lack the skills and usually lack the time needed to recognize, accurately assess and adequately monitor pain in people with dementia.
Educational resources and observational assessment tools are available. Persons with dementia may have difficulty eating. Whenever it is available as an option, the recommended response to eating problems is having a caretaker assist them. However, in bringing comfort and maintaining functional status while lowering risk of aspiration pneumonia and death, assistance with oral feeding is at least as good as tube feeding.
Tube feedings may cause fluid overload, diarrhea, abdominal pain, local complications, less human interaction and may increase the risk of aspiration. Benefits in those with advanced dementia has not been shown. A Cochrane review found no certain evidence about the immediate and long-term effects of modifying the thickness of fluids for swallowing difficulties in people with dementia.
Exercise programs may improve the ability of people with dementia to perform daily activities, but the best type of exercise is still unclear. A balance of strength exercise, to help muscles pump blood to the brain, and balance exercises are recommended for aging people. A suggested amount of about 2 and a half hours per week can reduce risks of cognitive decay as well as other health risks like falling.
A Cochrane Review highlighted the current lack of high-quality evidence to determine whether assistive technology effectively supports people with dementia to manage memory issues. Aromatherapy and massage have unclear evidence. Given the progressive and terminal nature of dementia, palliative care can be helpful to patients and their caregivers by helping people with the disorder and their caregivers understand what to expect, deal with loss of physical and mental abilities, support the person's wishes and goals including surrogate decision making, and discuss wishes for or against CPR and life support.
Person-centered care helps maintain the dignity of people with dementia. A Cochrane review found that remotely delivered interventions including support, training and information may reduce the burden for the informal caregiver and improve their depressive symptoms. The findings are based on moderate certainty evidence from 26 studies.
The most common type of dementia is Alzheimer's disease. The annual incidence of dementia diagnosis is over 9. The incidence of dementia increases exponentially with age, doubling with every 6.
Dementia impacts not only individuals with dementia, but also their carers and the wider society. Among people aged 60 years and over, dementia is ranked the 9th most burdensome condition according to the Global Burden of Disease GBD estimates. Until the end of the 19th century, dementia was a much broader clinical concept.
It included mental illness and any type of psychosocial incapacity, including reversible conditions. Dementia has been referred to in medical texts since antiquity. One of the earliest known allusions to dementia is attributed to the 7th-century BC Greek philosopher Pythagoraswho divided the human lifespan into six distinct phases: 0—6 infancy7—21 adolescence22—49 young adulthood50—62 middle age63—79 old ageand 80—death advanced age.
The last two he described as the "senium", a period of mental and physical decay, and that the final phase was when "the scene of mortal existence closes after a great length of time that very fortunately, few of the human species arrive at, where the mind is reduced to the imbecility of the first epoch of infancy".
Chinese medical texts made allusions to the condition as well, and the characters for "dementia" translate literally to "foolish old person".
Athenians Aristotle and Plato spoke of the mental decay of advanced age, apparently viewing it as an inevitable process that affected all old men, and which nothing could prevent. Plato stated that the elderly were unsuited for any position of responsibility because, "There is not much acumen of the mind that once carried them in their youth, those characteristics one would call judgement, imagination, power of reasoning, and memory.
They see them gradually blunted by deterioration and can hardly fulfill their function. For comparison, the Roman statesman Cicero held a view much more in line with modern-day medical wisdom that loss of mental function was not inevitable in the elderly and "affected only those old men who were weak-willed". He spoke of how those who remained mentally active and eager to learn new things could stave off dementia. However, Cicero's views on aging, although progressive, were largely ignored in a world that would be dominated for centuries by Aristotle's medical writings.
Physicians during the Roman Empire, such as Galen and Celsussimply repeated the beliefs of Aristotle while adding few new contributions to medical knowledge. Byzantine physicians sometimes wrote of dementia. It is recorded that at least seven emperors whose lifespans exceeded 70 years displayed signs of cognitive decline.
In Constantinoplespecial hospitals housed those diagnosed with dementia or insanity, but these did not apply to the emperors, who were above the law and whose health conditions could not be publicly acknowledged. Otherwise, little is recorded about dementia in Western medical texts for nearly years. One of the few references was the 13th-century friar Roger Baconwho viewed old age as divine punishment for original sin. Although he repeated existing Aristotelian beliefs that dementia was inevitable, he did make the progressive assertion that the brain was the center of memory and thought rather than the heart.
Poets, playwrights, and other writers made frequent allusions to the loss of mental function in old age. William Shakespeare notably mentions it in plays such as Hamlet and King Lear. During the 19th century, doctors generally came to believe that elderly dementia was the result of cerebral atherosclerosisalthough opinions fluctuated between the idea that it was due to blockage of the major arteries supplying the brain or small strokes within the vessels of the cerebral cortex.
In Alzheimer's disease was described. This was associated with particular microscopic changes in the brain, but was seen as a rare disease of middle age because the first person diagnosed with it was a year-old woman. By —20, schizophrenia had been well-defined in a way similar to later times. This viewpoint remained conventional medical wisdom through the first half of the 20th century, but by the s it was increasingly challenged as the link between neurodegenerative diseases and age-related cognitive decline was established.
By the s, the medical community maintained that vascular dementia was rarer than previously thought and Alzheimer's disease caused the vast majority of old age mental impairments. More recently however, it is believed that dementia is often a mixture of conditions. Inneurologist Robert Katzmann suggested a link between senile dementia and Alzheimer's disease.
This is shown by documented supercentenarians people living to or more who experienced no substantial cognitive impairment. Some evidence suggests that dementia is most likely to develop between ages 80 and 84 and individuals who pass that point without being affected have a lower chance of developing it.
Women account for a larger percentage of dementia cases than men, although this can be attributed to their longer overall lifespan and greater odds of attaining an age where the condition is likely to occur. Much like other diseases associated with aging, dementia was comparatively rare before the 20th century, because few people lived past Conversely, syphilitic dementia was widespread in the developed world until it was largely eradicated by the use of penicillin after World War II.
With significant increases in life expectancy thereafter, the number of people over 65 started rapidly climbing. Public awareness of Alzheimer's Disease greatly increased in when former US president Ronald Reagan announced that he had been diagnosed with the condition.
In the 21st century, other types of dementia were differentiated from Alzheimer's disease and vascular dementias the most common types. This differentiation is on the basis of pathological examination of brain tissues, by symptomatology, and by different patterns of brain metabolic activity in nuclear medical imaging tests such as SPECT and PETscans of the brain. The various forms have differing prognoses and differing epidemiologic Album) factors.
The main cause for many diseases, including Alzheimer's disease, remains unclear. Dementia in the elderly was once called senile dementia or senilityand viewed as a normal and somewhat inevitable aspect of aging. By —20 the term dementia praecox was introduced to suggest the development of senile-type dementia at a younger age.
Eventually the two terms fused, so that until physicians used the terms dementia praecox precocious dementia and schizophrenia interchangeably. Since then, science has determined that dementia and schizophrenia are two different disorders, though they share some similarities. After aboutthe beginning use of dementia for what is now understood as schizophrenia and senile dementia helped limit the word's meaning to "permanent, irreversible mental deterioration".
This began the change to the later use of the term. In recent studies, researchers have seen a connection between those diagnosed with schizophrenia and patients who are diagnosed with dementia, finding a positive correlation between the two diseases. The view that dementia must always be the result of a particular disease process led for a time to the proposed diagnosis of "senile dementia of the Alzheimer's type" SDAT in persons over the age of 65, with "Alzheimer's disease" diagnosed in persons younger than 65 who had the same pathology.
Eventually, however, it was agreed that the age limit was artificial, and that Alzheimer's disease was the appropriate term for persons with that particular brain pathology, regardless of age. Aftermental illnesses including schizophrenia were removed from the category of organic brain syndromesand thus by definition removed from possible causes of "dementing illnesses" dementias.
At the same, however, the traditional cause of senile dementia — "hardening of the arteries" — now returned as a set of dementias of vascular cause small strokes.
These were now termed multi-infarct dementias or vascular dementias. The societal cost of dementia is high, especially for caregivers. This steady increase will be seen not just within the United States but globally.
Many countries consider the care of people living with dementia a national priority and invest in resources and education to better inform health and social service workers, unpaid caregivers, relatives and members of the wider community. Several countries have authored national plans or strategies. There, as with all mental disorders, people with dementia could potentially be a danger to themselves or others, they can be detained under the Mental Health Act for assessment, care and treatment.
This is a last resort, and is usually avoided by people with family or friends who can ensure care. Some hospitals in Britain work to provide enriched and friendlier care.
To make the hospital wards calmer and less overwhelming to residents, staff replaced the usual nurses' station with a collection of smaller desks, similar to a reception area. The incorporation of bright lighting helps increase positive mood and allow residents to see more easily. Driving with dementia can lead to injury or death.
Doctors should advise appropriate testing on when to quit driving. They acknowledge that in low-severity cases and those with an early diagnosis, drivers may be permitted to continue driving. Many support networks are available to people with dementia and their families and caregivers.
Charitable organisations aim to raise awareness and campaign for the rights of people living with dementia. Support and guidance are available on assessing testamentary capacity in people with dementia.
