Why does the human brain age? Brain aging is a part of human life and a big part of society as the awareness for brain aging increases. Over time memory tends to become less efficient as we age and the neurons in the brain decreases (Bendheim, P.E. (2009). By 2050 in the US, 20 percent of the population will be 65 years or older. And as the elderly population increases, so will the incidence of age-related neurological disorders (Perlmutter, David. (2004). Therefor it is important to understand the aging brain, and how to keep the brain functioning as one ages.
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 healthy aging (Bendheim, P.E. (2009). Our human brain consist of living cells, which are constantly learning, as we referrer a small child’s brain as a sponge because it is constantly thinking and storing memories. When that child gets older, the brain will get older too, and it will be strong but response will slow down (Perlmutter, David. (2004). Alzheimer’s seems to always make the news, but it is not the only disease connected with the aging brain.
A healthy brain can have normal aging. A normal cognitive aging leads to predictable changes in thinking and memory that are associated with getting older (Memory impairment. (2010). The normal “healthy” brain aging is defined as aging without disease. Many elderly people do not exhibit symptoms of disease and live a normal, but never less they may display a little forgetfulness (Perlmutter, David. (2004). The normal brain aging differs from pathological aging caused by diseases that damage the brain, such as Alzheimer’s or cerebrovascular disease (Me...

For those with Frontotemporal dementia, 30 to 40 percent have a family history of dementia, suggesting the illness has a genetic component (Memory impairment. (2010).

- cognitive improvement Numerous studies showed that even in the aging brain, exer¬cise may help to create new brain cells. As observed by Nishiguchi et al. (2014), cognitive tasks in older adults can activate the brain and improve efficiency. Simultaneous cognitive and motor tasks may improve intellectual function when combined with exercise training, cognitive, and dual task (DT) exercises (Nishiguchi et al., 2014). For example, in a 12 week physical and cognitive exercise study using an RCT, Nishiguchi et al.... [tags: Exercise, Obesity, Muscle, Nursing]

- Memory problem and dementia was launched in 2002. Dementia is the term used to describe a set of symptoms, including impairment in memory, reasoning, judgment, language and other thinking skills. Dementia begins gradually in most cases, worsens over time and significantly impairs a person 's abilities in work, social interactions and relationships (mayo clinic 2016). The goal of Speak Up program and brochure on memory problem is to help the health care provider and patients become more informed and involved in their health.this brochure explained the what one should know about memory problem and dementia....

- Parkinson’s Disease (from hereon PD) is an extrapyramidal disorder characterized primarily by massive idiopathic degeneration of dopaminergic neurons in the substantia nigra, resulting in greatly decreased levels of dopamine in the striatum. The diagnosis, which is essentially a clinical judgment due to the lack, thus far of a simple diagnostic test, has historically been on the basis of the presence of at least two of the three main features of PD: bradykinesia (or akinesia or hypokinesia), rigidity, and resting tremor....

- i. How is the brain changing and developing. The old brain does not show any major change in the development of the brain because all of the parts of the brain have matured. During this period, the major focus of the brain is to repair and keep performing its activities as best as possible. People of this age group are the most vulnerable to getting diseases like strokes and Alzheimer’s disease. A person who has suffered a stroke can experience paralysis to one side of their body, which takes away their ability to do many physical activities....

- Music has always been an important part of our identity as human beings; it’s existed for millennia, transcending generations, languages, and cultures all around the world and affects each individual person differently – yet its effect is often profound. It has been proven through numerous tests and studies utilizing technologies like MRI that when exposed to music, certain areas of the brain are stimulated much more intensely than while not being exposed or doing other things. The auditory cortex is the specific region for processing sounds, but music actually stimulates other regions including those associated with emotions, movement, and memory; it is believed that music will activate the...

- We have known for a long time that chronic exposure to stress hormones, be it during prenatal period, infancy, childhood, adolescence, adulthood or aging, will have an impact on the brain structures involved in cognition and overall mental and physical health. The specific effects on the brain, behavior and cognition can depend on the timing and duration of the exposure as well as the interaction between gene effects and any previous exposure to environmental adversity. In an article by Lupien, McEwen, Gunnar, and Heim (2009), they hope to develop a model to explain why different disorders emerge in individuals exposed to stress at different times in their lives utilizing both animal and hum...

- Unhealthy Living, Alcohol intake and Effects on Normative Aging 1 The article in the Toronto star by Judith Timothy published on September 26, 2013 titled, “Alcohol: the modern woman steroid?” this article deals with elderly adults and alcohol. I find this article interesting because of the high rate of alcohol related accident, illnesses, and cognitive decline in older adult. The stereotype surrounding elderly adult and how alcohol, and alcohol consumption is link to ageing. The exploration of this topic Unhealthy Living, Alcohol intake and Effect on Normative Aging will enable us understand better the effects of alcohol on health of older adult....

- We’ve all experienced going to a college or high school reunion and being shocked by the appearance of some of your classmates. They look older than they should and yet there are others who seem to look just about the same as they did when they were your classmates. It really is a mixed bag, and as we get older and go to a class reunion the results of the human aging process are even more stark. Some of your classmates who were stars on the football team or outstanding athletes in other sports are bent over, bald and fat.... [tags: Ageing, Gerontology, Senescence, Aging]
