For those committed to applying scientific approaches to dementia, as I am, appreciating the bigger social picture is critical. Words and stories matter greatly in this process of change. Intergenerative is a new word that focuses attention on innovation via the exploration of the spaces between concepts like disciplines and professions.

Thus the future poses intergenerational ethical issues that the relative distribution of resources to children and elders and to those with dementia now and those threatened by it in the future.

Introduction to Biochemical Pharmacology and Drug Discovery

Ecopsychosocial is another new term designed to extend the biopsychosocial model of health by making explicit the need to view ecology as a dominant form of biological thinking in relationship to disease 1.

Ultimately evolutionary anthropological approaches in medicine are needed that look at changes in genes and environment over time in relationship to each other and to culture. In this review I will explore the larger context of work in dementia focusing on aging, health, the environment, economics and ethics and will then examine the state of the science in relationship to these broader perspectives.

Finally I will end with a brief discussion of priority setting and next steps that should be considered. Context Aging demographics are often repeated like a mantra in the field of AD to emphasize the growing number of elders at risk for dementia. Statistics are used to calculate that someone is newly affected diagnosed or labeled?

Moreover we are driven to believe that early diagnosis will improve outcomes, although how early and of what and for what purpose are questions that are only rarely asked. For decades and year after year there has been an almost obsessive ritual of making claims that within five years there will be cure or at least an effective intervention for AD, the outcome from which is inevitably unrealized.

How long: i can the assertion that we are close to a cure maintain its credibility if it has not already been lost and, ii do repeated claims of breakthroughs lead to a breakdown of trust?

Within the context of a demographic shift in the number of at-risk elders is also a cultural shift towards reinventing aging itself. Attitudes about health care are also changing resulting in significant transformations in existing healthcare systems. Chronic diseases of all kinds are becoming more common, not only in elders, but also in children [ 5 ]. Individuals are being increasingly asked to take more responsibility for their own health through programs of chronic disease self-management 4 such that the provision of healthcare services in homes and the community, rather than institutions such as hospitals, is desirable.

How individuals with varying degrees of cognitive impairments will deal with this increased responsibility and control of their own health is uncertain. Navigating healthcare systems is difficult enough for people with normal intellectual abilities, let alone those with dementia.

Chronic disease self-management programs will therefore have to have as a priority the need to adapt to having participants who might have trouble learning and ultimately changing their behaviors. The epidemiology of dementia will change with, for example, more head injuries related to global conflict and natural disasters and changes in the patterns of infectious diseases affecting the nervous system, like malaria. Individuals with dementia will similarly be more at risk for harm from environmental events like droughts, floods, and storms.

As public health disasters will likely consume more and more of our health care dollars, economics will likely continue to stutter along as a focus on growth and development reaches the limits of available and essential natural resources. The education and health of children will also become even more important social priorities as dependency ratios number of old retirees to young working citizens increase.

The foundations of modern industrial and agricultural capitalism, e. Capitalism itself is being reframed as conscious or natural capitalism with greater attention to social and environmental responsibility [ 7 ]. The emergence of information technology is a vital source of innovation.

Mobile computing, social networking, augmented reality, gamification, digital multimedia and transmedia, together with increasingly smarter and more sympathetic computers and other digital devices, e. Google Glass, will transform the consequences of aging and help humans in general with their own cognitive challenges including dementia. But this technology will not only support intellectual activities like education and research, but the arts and humanities and other aesthetic and value-related endeavors.

Dance, supported by multimedia or not, is an ideal form of integrated physical movement, music, cognitive and social activity and storytelling. So-called brain fitness approaches e.

Luminosity, Brain HQ, while subject to exaggeration offer real promise 8. Creating new narratives 9 in innovative learning spaces will also provide a beacon of new hope 10 , 11 , Whether it be the materialistic me-too generation or the next quarter financial performance orientation of corporations, we need to change to frameworks of engagement with the world that support thinking and valuing for the long-term.

Science as a religion, i. An extreme example of this false hope is the anti-aging medicine practitioners of the world who claim that aging itself is a disease process that can be eliminated or even reversed [ 13 ]. But the anti-aging movement claims that aging is an actual disease and that we can slow aging today with various pills and potions and eventually cure it tomorrow.

If AD shares the same biology as forms of severe brain aging and there is really no convincing and consistence evidence to the contrary , then how do we distinguish quackery and pseudoscience from the excessive promises of the mainstream AD science establishment?

How can an evangelical genomics that claims an understanding of DNA as the foundation for defining health be challenged for ignoring the effects of the environment on genes and health i. The promises of financially rewarding intellectual property IP is the basis of the pharmaceutical industry with even the patenting of genes being possible, although is now more controversial [ 14 ]. This unethical behavior all to often extends to physicians and other health care practitioners but may be in the process of achieving balance with grassroots pushbacks on drug prices [ 17 , 18 ].

Since the AD field is based on true hype and much false hope, expectations for the future will be based on taking a deep and honest look at where the field have been, is currently and then being open to other possibilities that may well change current concepts about the nervous system, aging, expertise, science, and for-profit models. State of the science During the past 25 years we have seen two hypotheses dominate the AD research field, the arguably true but limited so-called cholinergic hypothesis [ 19 , 20 ] and the currently fashionable but weakening amyloid hypothesis [ 21 , 22 ].

Both can be framed more narrowly in clinical and scientific terms but as general claims to importance they reflect more the current practices, politics, and fads of the Alzheimer field and science in general.

The cholinergic hypothesis was based on a systems focus on neurotransmitters, their receptors and neural circuits and claimed that acetylcholine, especially nicotinic cholinergic systems, were important for memory and attention [ 19 ].

In AD and related dementias the cholinergic basal forebrain is characterised by neuronal loss. One could argue that this hypothesis was actually somewhat successful clinically as cholinesterase drugs were approved based on the scientific understanding of the role these networks play in normal cognition and disease.

However at a social level these drugs have largely failed because economically, in terms cost utility analysis, they do not produce adequate benefit, i. When medical science in general moved from a systems neuroscience perspective to genetics and molecular biology, an opportunity emerged to replace the cholinergic hypothesis with one that was said to be more powerful, i.

Here the identification of the genes that affect amyloid processing in early onset, familial AD EOAD appeared to suggest that interventions at this level could lead to therapies that might more directly alter the basic pathogenesis and prevent cell death rather than merely improve neurotransmitter function [ 23 ]. The excitement, if not frenzy in the field, could be felt as scientists began to promise cures in a matter of years [ 24 , 25 ].

However, despite billions of dollars being spent on the basic biology and extensive clinical trials, largely focusing on therapeutics and vaccines that modified aspects of the amyloid cascade, there have been no effective therapies [ 22 , 26 ].
