Maintaining productivity beyond 60 years old depends, in large part, on maintaining a level of cognitive ability that allows a person to continue to interact effectively and appropriately with the environment. Cognitive decline is becoming a more prevalent, frightening, and expensive personal and social problem – but a problem that companies can more effectively address with innovative products and services.
The world population is rapidly ageing and cognitive impairment (CI) is a fast growing problem
Cognition is the integration of mental functions such as attention, memory, producing and understanding language and communication, learning, reasoning, problem solving, and decision making in order to process an adaptive behavioral

The fear of one day developing dementia is growing, with good reason, as deaths from AD have risen by 66% in the past few years - making it the sixth leading cause of death in the USA (Alzheimer’s Association 2011 facts and figure reports).
Cognitive Decline is not a disease but a syndrome related to many lifestyle and health influences
As the brain ages it becomes less efficient and less functionally effective thus impairing every aspect of cognition. This is a result of the accumulation of deterioration that leads to the loss of neuronal integrity and ultimately noticeable impaired cognitive functions. It is now well established that oxidative stress is a key risk factor in the etiology of cognitive dysfunctions. The brain is very sensitive to free-radical oxidative damage because of its high consumption of oxygen and its high concentration of lipids that are prone to oxidation. This rate of damage accumulation depends upon the level of exposure to many biological and psychological risks factors. For example: Inflammation; hormonal imbalance; insulin resistance; anxiety; depression; and lack of stimulation and social interaction are all implicated in the rate of long term CD.
Key facts
Cognitive impairment is a syndrome in which there is deterioration in memory, thinking, behavior and the ability to perform everyday activities.
Although cognitive impairment mainly affects older people, it is not a normal result of ageing.
Worldwide, 35.6
In times past many people thought that memory loss was a normal occurrence for elderly people. This thinking was major reason for why Alzheimer’s disease was not caught until very later in the stages. Alzheimer’s disease is not a normal part of aging. After heart disease, cancer, and strokes, Alzheimer’s is the most common cause of death in adults in the Western world. “It is estimated that 4.5 million Americans over the age of 65 are affected with this condition. After the age of 65, the incidence of the disease doubles every five years and, by age 85, it will affect nearly half of the population” (Robinson).
One of the most prominent and perhaps most feared condition associated with aging is dementia. The family of disorders can cause individuals to lose their mind, reducing one from being a complex, thinking, feeling human being to being confused and vegetative, unable to recognize their loved ones. Serious dementia affects nearly 37 million people globally, but predictions of how those numbers will change over the next few decades are conflicting (textbook). Although we know dementia as to do with damage to nerve cells in the brain, there are ongoing studies looking at correlations between other health issues and these types of diseases.
Dementia is a disease which causes mental debility and affects one’s way of intelligent, attentiveness, recollection and problem-solving (NHS, 2013). As a result of dysfunction of brain cells in some parts of the brain it affects the thinking process then dementia occurs and it usually comes with age (Ibid). It is estimated that 560
Dementia is a condition resulting from obtained brain disease and distinguished by progressive decay in memory and other cognitive fields such as judgment, abstract thinking, language, and executive functioning. This disease is usually caused by degeneration in the cerebral cortex, the part of the brain responsible for thoughts, memories, actions, and personality. Death of brain cells in this area leads to the impairments that distinguish dementia. Though the cognitive outline of single diagnosed with dementia vary somewhat by etiology, the degree of deterioration stands for a decrease from previous levels of cognitive functioning and is enough to impede with social and occupational functioning. This downfall is beyond what might be expected from normal aging in a person. It can cause impairment with everyday activities such as dressing, feeding, and bathing.
An estimated 47.5 million people suffer from dementia. Every 4 seconds one new case of dementia is diagnosed. Dementia is a term that describes certain symptoms such as impairment to memory, communication and thinking. It is a group of symptoms and not just one illness. Even though one‘s chance of getting dementia increase with age, it is not a part of aging. Dementia is usually diagnosed after a series of assessments that includes a physical evaluation, memory tests, imaging studies and blood work. It affects three aspects of one’s mental function, cognitive dysfunction (Problems with memory, language, thinking and problem solving), psychiatric behavior (changes in personality, emotional control, social behavior and delusions) and difficulties with daily living activities (driving, shopping, eating and dressing). “The median survival time in women is 4.6 years and in men 4.1 years” (Warren, 2016).
Alzheimer’s Disease Alzheimer’s Disease is a progressive, degenerative disease that attacks the brain and results in impaired memory, thinking and behavior (Internet). It is a degenerative disease affecting nerve cells of the frontal and temporal lobes of the cerebrum of the brain. The disease is the major cause of presenile dementia (i.e., the loss of mental faculties not associated with advanced age) and is thought to be the largest single cause of senile dementia as well (Britannica, 306). It causes the connections between cells to become ineffective and the cells themselves to shutdown and eventually die (Davies, 1). Alzheimer’s is a progressive, irreversible, fatal neurologic disorder that affects an estimated 4 million American adults. It is estimated by 2040,approximately 14 million Americans will be diagnosed with Alzheimer’s Disease. Approximately 9% of the population older than 55 years and 20% of those older than 85 years have Alzheimer’s Disease. The duration of AD averages 2 to 10 years but can be up to 20 years. By 1992, Alzheimer’s Disease was the fourth leading cause of death among adults (more than 100,000 American deaths per year). It is projected that the number of people with Alzheimer’s Disease will triple in the next 50 years. This epidemic of dementia is not confined to sex, race, social, or economic class. The public knows this disorder as “senility”, although the term Alzheimer’s is becoming more common (Rosdahl, 1356). According to a quote from
Dementia is a disease that has been characterized as a deficiency of permanent memory which leads to a decrease in recent memory that can interfere with the ability to engage in professional and social activities (Hamdy, Hamdy, Hudgins, & Piotrowski, 2014). Even recent studies have shown that dementia is not a part of the normal aging process, it has become a very serious and common condition among the older population. An estimated 35.6 million people, with 7.7 million cases diagnosed each year are affected with dementia according to the World Health Organization (WHO) (Hamdy, Hamdy, Hudgins, & Piotrowski, 2014).
Awareness is necessary in understanding this disease. As humans continue to live longer, the risk for many illness and deficiencies begin to present them. Alzheimer’s and dementia is one of the many problems that plague the aging population. Understanding brain aging and reducing risk for neurological disease with age requires searching for mechanisms and treatment options beyond the age-related changes in neuronal
Dementia is not a disease but rather a group of symptoms caused by disorders that affect the brain (National Institute of Neurological Disorders and Stroke, n. d). The hallmark of dementia, memory impairment, is accompanied by deficits in language, motor function, recognition, or executive function (Stahl, 2013). The most common forms of dementia are caused by Alzheimer’s disease (AD), vascular dementia, Lewy body dementia, and frontotemporal lobar degeneration (Prince et al., 2013). The risk of dementia increases with age. Dementia is rare below the age of sixty but affects about 17% of those between 80 and 85 years of age, 33% of those between 85 and 90 years old, and 50% of those over 90 years of age (Tom et al., 2015). As the
Alzheimer 's is the most common form of dementia, a general term for memory loss and other intellectual abilities serious enough to interfere with daily life. Alzheimer 's disease accounts for 60 to 80 percent of dementia
Alzheimer’s disease (AD) is incurable disease of the brain that slowly destroys a person’s memory. It normally appears gradually and progressively gets worse over time. AD is also a form of dementia which is the most common in the United States. Alzheimer’s is characterized by loss of progressive memory, decline in cognitive skills and changes in behavior. Approximately 5.4 million Americans have AD and 96% of those Americans are over 65 years old. (Moschetti, Cummings, Sorvillo, Kuo, 2012)
Over the last several decades, one of the diseases that continues to cause concern and difficulties during the later years of life is mild cognitive impairment (MCI). Mild cognitive impairment ranges from minimal loss of cognitive problems to the point it changes normal life. Large changes in our demographics have occurred during the twentieth century. Life expectancy has increased by over thirty years. When you factor in the increase of fertility problems, the age groupings shift dramatically (Mohajeri, Troesch, & Weber, 2014). These changes impact the demand for health and long-term care, as well as expenses for pensions and social security (Mohajeri, et al., 2014). Another factor adding to this situation is, health expectancy is 8
Cognitive aging is worthy of study for many reasons. The more knowledge that is uncovered about cognitive aging, the closer to possibly finding ways to slow the process down, decrease the intensity of the symptoms, or maybe prevent it all together. If there are possible ways of doing so it is important to find them. The “what” and “when” of cognitive aging has made advances, but the “why”, “where”, and “how” are still to be uncovered. We further our knowledge of the “why”, “where”, or “how”, or uncover the full truth, without knowing the full truth about the “what” and “when”. Finding out more about one might lead to learning more about another. Expanding our knowledge on cognitive aging has the potential to increase someone’s quality of life. It has the potential to increase that family member’s quality of life. Cognitive aging effects more than the victim, it effects their
As humans begin to get older, there is a strong association between age change and the decline of cognition. There are many causes of this decline, and it often varies highly between individuals based on their lifestyle and physical activity level (Brown AK, Liu-Ambrose T, Tate R, Lord SR, 2009). This a concern that many individuals have as they start to get older, especially with the media coverage that Alzheimer’s disease has been getting. Degenerate diseases such as Alzheimer’s can also be a major cause of cognitive decline and are common in elderly populations. Because of this risk, there are many who are looking to improve or maintain their cognitive abilities or those of a loved one, as there is an expectation that even in old age,
What exactly is dementia? By definition, “Dementia, which is from the Latin word dement meaning ‘without mind,’ is a progressive deterioration and eventual loss of mental ability that is severe enough to interfere with normal activities of daily living, lasts more than six months, not present since birth, and not associated with a loss or alteration of consciousness” (Thomasson, 2014). Dementia is usually caused by a loss of brain cells in the cerebral cortex of the brain, the part responsible for thoughts, memory, actions, and personality (Thomasson, 2014). The loss of brain cells in this part of the brain usually leads to what is called cognitive impairment which can at some point be diagnosed as dementia (Thomasson, 2014). What a lot of
