The search to find therapeutic targets in Alzheimer's disease (AD) has been dominated for over 25 years by research into the roles in the initiation and progression of dementia of the amyloid beta protein (Aβ) [1, 2], derived from the β-pathway of amyloid beta protein (AβPP) cleavage.
An ancient Indian subcontinent parable tells a story in which a group of blind men each touch a different part of an elephant. They cannot agree on the nature of the elephant because none of them observed the elephant as a whole.

Alois Alzheimer might have mentioned plaques and tangles in a single short paper on pre-senile dementia in 1907, but it was the co-discover of Alzheimer’s disease (AD), Oskar Fischer, who in that same year far more extensively reported neuritic plaque in 12 cases of senile dementia, a condition which he and many others refused to differentiate from Alzheimer’s “pre-senile” dementia.

Music is a wonderful, non-pharmacological intervention to be considered for persons with Alzheimer’s disease (AD). In order to provide appropriate and beneficial music interventions for persons with AD, it is important to understand the range of music experiences that may offer effective complementary management of symptoms associated with AD.

The World Health Organization  has declared dementia as public health priority. Alzheimer’s disease (AD) is the most frequent cause of dementia. The challenges to governments to respond to the growing number of people with dementia are substantial. Tremendous efforts have been made in research during the last four decades highlighting important aspects of the pathogenesis of AD, but if the cause of AD is not defined, and treatments to prevent the disease are not provided, the world will face an unprecedented health-care problem by the middle of the century.

There is increasing concern not only in Alzheimer’s disease (AD) research, but all of modern investigations, that false findings may be the majority or even the vast majority of published research claims .

Alzheimer’s disease (AD) is the most common cause of dementia and remains incurable. Its prevalence is rising, current afflicting 5 million Americans with projections to affect millions more as the population ages .

Among patients diagnosed with Alzheimer's disease (AD), the percentage in the severe stage ranges from 28%  to 33%  to a maximum of 50% . In institutionalized patients, prevalence is higher, with an estimated 75% of patients with severe AD .

There is no doubt that nutrition is involved in brain health and the development of neurodegenerative diseases. This is an important area of research in the dementia field that has suffered from the absence of trained experts in nutrition and nutritional epidemiology.

Most of us harbour in our body several types of herpes virus—perhaps as many as five—and we provide them with a safe and secluded haven for life, as there are no methods for eliminating or expelling them.

The ability to maintain normal psychological and physical functioning and avoid serious mental illness when exposed to stress and trauma, a phenomenon known as resilience, is a topic that has been investigated over the past several years with increasing attention [1,2].

As disease-modifying drugs are crucially missing from the pipeline of treatments available for people with Alzheimer’s disease (AD) or related disorders, physicians, scientists, and public health experts are promoting the concept of early diagnosis.

Alzheimer’s disease (AD) transgenic mice have been used as a standard model for AD drug discovery and basic mechanistic studies. These mouse models overexpress amyloid β precursor protein (APP) or APP/presenilin (PS) with single or multiple familial AD (FAD) mutations, which lead to excess accumulation of amyloid β (Aβ), a well-known driver for AD pathogenesis.

The microtubule-associated protein tau is mainly expressed within neurons where it performs its physiological function of microtubule stability. However, extracellular tau is found in models of tau overexpression in which neuronal degeneration and cell death is prominent.

The field of Alzheimer research has reached an impasse after more than 100,000 clinical and scientific papers published in the last 40 years, because there is yet no hope, no effective treatment, and no knowledge of what causes this dementia.

For most people, older adulthood is associated with some decline in memory and in some aspects of cognitive function. These are age-related changes  that are widely expected, understood, and accepted by the general public.

Over the past few years there has been tremendous progress in diagnosis and therapeutic trials on Alzheimer’s disease (AD) and related dementias. Overall, the cost/benefit relationship is shifting with success.

Depression in Alzheimer’s disease (AD) has a substantial impact on disability, disease progression, and caregiver burden. Furthermore, depressive symptoms in normal aging, as well as in mild cognitive impairment (MCI), are associated with cognitive and functional decline.
Two hundred issues and nearly twenty years have positioned JAD at the center of printed and electronic peer-reviewed publications in Alzheimer's disease, as a venue that reflects the breadth of research in the field worldwide.
