Alzheimer’s disease known to be a neurological disorder of the central nervous system is an irreversible disorder in which brain cells deteriorate resulting to loss of our cognitive functions, primarily memory, movement coordination, reasoning and judgment, and pattern recognition. In its advanced stage, all memory and mental functioning could be lost (Healthcommunities.com, 2016). This disease is known to be caused by parts of the brain shrinking (atrophy), which destroys the structure and function of particular areas of the brain (Nhs.uk, 2016). Although the exact cause to this process is not known, research suggest that in the brains of patients with Alzheimer 's disease, scientists have found amyloid plaques (abnormal deposits of protein), neurofibrillary tangles containing tau and acetylcholine a chemical imbalances (Nhs.uk, 2016).

The brain changes in size and weight as a person ages. There is also a narrowing of the gyri, enlargement of the ventricles, and widening of the cerebral sulci. In AD, these changes are accelerated, causing issues such as atrophy of the cerebral cortex and loss of cortical neurons. In addition, the pre-central gyrus of the frontal lobe, superior temporal gyrus, hippocampus, and substantia nigra are all affected. Changes in neurofibrillary tangles (tangled masses of fibrous tissue throughout the neurons) , amyloid-rich senile or neuritic plague (degenerating nerve terminals in the hippocampus which contain proteins that form neurotoxic plague in the brain) and granulovascular degeneration can all occur as well.

In recent years there have been a myriad of ground breaking discoveries in science. However, I believe more can be done in neurology as we have a worldwide ageing population with dementia affecting many sufferers and their families. I wish to study neuroscience as I would like to examine conditions such as this but also investigate other aspects of the brain such as neuroanatomy. Having had a close family member diagnosed with Alzheimer's disease, I've been exposed to the fragilities of the human brain from a young age. Even though watching the slow deterioration has been distressing, I have also found it very interesting to see how such a complicated organ can be subjected to such large changes due to a degenerative condition. As a result of this personal experience, my desire to study the intricacy and complexities of the brain has substantially increased.

In addition, decreased cerebral blood flow, environmental toxins and a decrease in acetylcholine have all been labeled potential culprits. Various theories for the cause of Alzheimer’s have been put forth but as yet none have been shown true.

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.

Age-related declines are not constant across brain regions. Moreover, patterns of brain aging differs among individuals. Post mortem (PM) studies cannot help in assessment of brain tissue and its components. Moreover, PM cannot provide information on dynamic process of adult brain development, and its connection with brain structure and function. MRI helps in in-vivo measurements of the brain. It was realized that there is cortical thinning as age progresses. . Some studies of cortical thickness failed to replicate stability of the primary sensory regions (e.g., calcarine cortex) (Fjell et al., 2009; Salat et al., 2004) while others found that cortical thinning in frontal and parietal lobes exceed that of the temporal and occipital regions (Thambisetty et al., 2010). It is suggested that myelin is related to shrinkage in cerebral cortex or responsible for loss of cortical volume. MRI has helped evaluate leukoaraiosis which is a change in white matter integrity that is displayed on a T2-weighted MR image as a high signal intensity area. This area is defined as white matter hyperintensities (WMH) which depicts pathological processes such as ischemic lesions, gliosis, axonal degeneration, loss of myelin, microinfarcts, and expansion of perivascular spaces (de Leeuw et al., 2001; Pantoni, 1998). WHM is observed around the borders of the ventricles and deep in the subcortical WM regions. WHM is not present in health adults until the age of 50-55 (Hopkins et al., 2006). Further,

It is full of comprehensive and engaging style; well reference and scientifically proven, summarizes the current revolution in neuroscience and neuroplasticity, and closes the gap that the old age or matured brain, which is unchangeable is changeable and malleable (plastic); extending it functions from one region to the other. Doidge engaging style of writing, scientific proves, and academic tone help to make the book persuasive.

Alzheimer’s disease (AD), is a type of dementia that no one would ever want their grandmother or grandfather to suffer from, as it destroys memory and other important mental functions of its sufferer. Alzheimer's disease is currently ranked as the sixth leading cause of death in the United States. While the age 65 and older is its target age, it has consumed the lives of over 1.9 million people. The brain begins to show signs of damage in the hippocampus, the part of the brain essential in forming memories. As more neurons die, parts of the brain then begin to shrink. By the final stage of Alzheimer’s, damage is widespread, and brain tissue has shrunk significantly. The idea that Alzheimer’s disease is related to age in 1974 was introduced

The necessity to integrate this knowledge when caring for the older population is desirable because the population above 55 years is among the fastest growing population in America according to the U.S. census (2010). Tolson Booth & Schofield (2011) discuss that older people are at a greater risk of developing delirium following an age-related impairment of cerebral metabolism, which causes a significant decrease in the synthesis of neurotransmitters, in particular, acetylcholine. According to Hosie, Lobb, Agar, Davidson, and Phillips (2014), older people are often affected by at least one chronic condition such as dementia. Unlike delirium, dementia is a chronic condition that lasts at least six months and in most cases occurs progressively. Also, the most common form of dementia, Alzheimer’s disease (AD), is associated with a chronic decline in acetylcholine (Redfern & Ross, 2006). Therefore, this explains why symptoms of dementia and delirium overlap, especially memory loss in both conditions. The overlapping symptoms, therefore, make differentiation between the two conditions difficult, especially when delirium is superimposed on dementia. It is because of this that identifying delirium is of great significance to the older population.

As the population keeps aging, Alzheimer 's Disease (AD) is becoming a more significant public health issue. The prevalence of AD is expected to reach 34 million worldwide by 2025 (Mount 2006) and with the aging demographic, early diagnosis and treatment of AD is gaining importance. Cognitive decline and altered brain function related to AD has been shown to be present years before the clinical onset of the disorder through functional brain imaging techniques (Prvulovic 2011). Emphasis has been on detection of AD in its preclinical stages to provide early interventions for the patients. Since Fuld et al.(1990) 's study suggesting that the examination of cognitive functioning in non demented older adults is predictive of prospective dementia, countless studies have attempted to devise reliable methods of detecting cognitive changes and risk factors in preclinical populations.

Alzheimer’s disease, first described in 1907, is the fourth leading cause of death in the United States (Ramachandran, 2016). This disease gets worse gradually over time. People, predominantly women, are expected to live approximately eight to ten years after diagnosed (Bird, 2015). According to the Alzheimer’s Disease Association, there are approximately three million cases in the United States each and every year alone (Association®, 2016). People with Alzheimer’s disease suffer from a wide range of difficult incurable problems. Alzheimer’s disease is believed to prevent correct workflow of the 100 billion nerve cells in the human brain. Oxygen sluggishly being supplied to the brain causes several Alzheimer indicators to occur; memory loss, behavior changes, slurred speech, poor judgment, and hallucinations. According to Bird, 95% of patients with Alzheimer’s are over the age of sixty-five (Bird, 2015). At the age of sixty-five individuals brain activity starts to slow causing build-ups.

Research indicates that cases of Alzheimer’s disease involve “…damage to improper function of on or more of these brain areas…: the prefrontal lobes, the hippocampus, amygdala, and diencephalon (van der Flier et al., 2005; Caine et al., 2001). Researchers have also identified biochemical changes that occur n cells as memories form; studies suggest that acetylcholine and glutamate are in low supply or at lease function differently, in the brains of Alzheimer’s victims (Chin et. al.., 2007; Akairke,

As age increases, we can expect some loss of heart, lung, joint, and sexual functioning. Some loss of brain cells and mental efficiency is a normal part of

It is clear to neurobiologists that aging results in a decrease in brain size as well as a decrease in the efficiency of brain functions. It has been a widely held belief that aging causes neurons to die and for the overall number of neurons to decrease as one reaches old age. Studies

Companies are providing training as a means to increase demand for their products and services in the competitive marketplace. Training programs' importance has been increasing. All companies try to increase programs' costs and effectiveness so they research new techniques. But they must develop programs with thinking the future. Solves which's effectiveness is short should not important for companies. They research new techniques which effectiveness continues long time. Analyzing future is ver important for success.
