Alzheimer’s disease is a neurodegenerative disease that disrupts a person’s memory, thinking abilities, and behavior. This disease affects three major areas in the brain; the cerebrum, the cerebellum, and the brain stem. As the disease begins to take effect, these parts of the brain become obstructed, and the information that is supposed to be transmitted between neurons is hindered. The information that is responsible for sensory, learning, and memory progressively digress’ in productivity. Alzheimer’s disease causes nerve cell death and tissue loss all around the brain, which reduces the brain’s ability to function at a rapid pace and comprehend basic signals (“Alzheimer’s & Dementia,”n.d.). As parts of the brain begin to deteriorate, normal functions begin to drift away as well.
The cerebrum makes up three quarters of the brain. In the cerebrum, there is the ability to problem solve, move, think and feel (“Alzheimer’s Disease,”n.d.). The cerebrum can be divided into two halves, the right hemisphere and the left hemisphere. Each hemisphere has four lobes, occipital lobe, parietal lobe, temporal lobe, and frontal lobe. Each lobe has specific tasks. For example, the occipital lobe is responsible for visual images.

To further look at the root or the causes of dementia, it all comes down to the neuron. There are billions of neurons within the brain, and each of them receives messages through the dendrites or stems of the neuron. As the message is received, it travels through the axon of the neuron to the terminal button (Feldman, 2010). Every neuron is interconnected by the synapse, a microscopic gap between neurons, which enables the message to continue traveling throughout the brain. There are proteins located in and on the neuron that is secreted by enzymes. A large protein called APP is broken down into protein beta-amyloid and Tau
Alzheimer’s disease is a common problem in today’s society and within the older population this disease makes up the largest form of dementia. Although it is a problem in mainly older people, this disease can still occur in the younger population also. People in their 30s-50s can be diagnosed with this disease, even though it is not as common as people in their 60s-90s. The number of people with Alzheimer’s in the U.S. is close to five million and is expected to double within the next 30 years. With our modern medicine and advancements one would think a cure would be available, however, getting to the cause of the disease is a major factor. The cause of Alzheimer’s disease is one that is very debatable and questionable and most likely is a result of multiple factors rather than one. The main issue with finding the cause is because this disease affects the brain and can
Alzheimer’s disease is the 6th leading cause of death in America. It kills more than breast cancer and prostate cancer combined. Alzheimer’s accounts for 70-80% of dementia cases. By the age of 65, 1 in 9 people are diagnosed and by the age of 85, 1 in 3 people will have the disease. According to the Alzheimer Association, 5 million people in American have Alzheimer’s. Alzheimer’s starts to form 20 years prior to being diagnosed. Learning about Alzheimer’s can help families understand how Alzheimer’s is more than just memory loss, it is an incurable mental disease.
The disease stem cells could fix is called Alzheimer’s Disease (AD). The reason I chose this topic is because I have seen first hand how badly someone who suffers from Alzheimer’s Disease is affected in their daily lives. This disease completely takes over their lives and they turn into a completely different person who can hardly function. AD is very tough on the loved ones of the person suffering from it because that person, most of the time has no idea what is going on or who their loved ones are. The memories for people with AD is completely gone and even the simplest tasks such as remembering to use the bathroom becomes difficult. The way stem cells could be feasible is because stem cell-based therapies could potentially treat
Alzheimer 's disease (AD) is a progressive degenerative disease of the brain from which there is no recovery. There are three brain abnormalities that are the hallmarks of the Alzheimer’s disease is initially caused by plaques buildup in the brain’s neurons as illustrated in figure 1. The support structure that allows the flow of the nutrients through the neurons gets damaged and ultimately there is loss of connection among the neurons and they die off (National Institute of Health, 2015). This causes the brain tissue to shrinks, which is called atrophies. All this ultimately lead the victim of this disease to face difficulties in governing emotions, recognize errors and patterns, coordinate movement, and remember. Ultimately, a person with AD loses all memory and mental functioning.
Alzheimer’s Disease has been one of the top leading causes of death in our country. It is understood that this disease is identified as an excess of the protein amyloid-ß within an increase of plaque (Seneff, Wainwright, and Mascitelli, 2010). Additionally, as the brain ages, it gets used to the inflammation and oxidative stress, so it is important to take the right amount of antioxidant micronutrients like vitamin C and vitamin E as well as anti-inflammatory macronutrients such as omega-3 polyunsaturated fatty acids to protect the brain from ageing (Whalley et. al, 2004). This is a devastating disease that affects most people over the age of fifty. Recently, there have been many studies done to figure out what causes this disease, if there is anything that can cure it, and how to prevent the disease. Seneff, Wainwright, and Mascitelli, believe Alzheimer’s develops with consuming too many carbohydrates, especially fructose and having a deficiency in cholesterol and dietary fats as well (2010). Whalley, Starr, and Deary have seen that poor diet, poverty, and failing health are links to developing Alzheimer’s Disease (2004). Furthermore, seeing increase in plasma homocysteine concentration increases risk of Dementia, which can result from an inadequate intake of vitamin B12/folate (Walley et. al, 2004). Additionally, Gray supports Walley’s findings and even believes having an adequate intake of vitamin B12/folate will have a positive effect on the overall health
Alzheimer’s is a systemic disease, meaning that it affects more than one part of the body. There are three major systems that are affected by Alzheimer’s. The first involves the Central Nervous System. The CNS includes the brain and spinal cord, allowing the nervous system to make the spinal cord and brain function. The Central Nervous System is affected because specific brain proteins begin to malfunction and brain cells die. The loss of brain cells is the reason for memory loss and
In a study that was done called aging, demographics and memory study (ADAMS) it was found that older African Americans are two times more likely than older whites to develop Alzheimer or any other dementia. Some of the reasons that have been discovered as to why older African Americans are more common to have Alzheimer’s is because they are found to have higher rates of high blood pressure, diabetes, along with other vascular diseases. Some other factors that can affect who may end up with Alzheimer’s are lower level of education, and socioeconomic characteristics which are found to be more common in African Americans. In the health and retirement study (HRS) 80% of African Americans were found to have high blood pressure. Other risks that have been found to have increased risk of Alzheimer’s are those with lower educations, low income being below $18,000 a year, and
Alzheimer’s disease is a prominent brain disease that effects a massive amount of individuals in the United States. Alzheimer’s disease (AD) is the sixth leading cause of death in the United States, accounting for 60-80% of dementia cases, with no chance of being cured, prevented or decelerating over time (Alzheimer’s Association, 2014). AD is the most well-known form of dementia, causing complications in brain function in the areas of memory, thinking, and behavior (Alzheimer’s Association, 2014). In an effort to gain a deeper understanding of Alzheimer’s disease, researchers create new knowledge about the disease, which is then distributed to the public. The goal in this information disbursement is to find new and inventive ways to treat AD, prevent AD from progressing at such a rapid pace, and aid in the quality of life in those diagnosed with AD as well as caregivers and medical professionals providing treatment to individuals’ with AD.
“There is one thing Alzheimer 's cannot take away, and that is love. Love is not a memory - it 's a feeling that resides in your heart and soul.” (Fade to Blank). The human brain is a remarkably complex organ that processes, stores, and recalls information. “Alzheimer 's disease (AD) is a slowly progressive disease of the brain that is characterized by impairment of memory and eventually by disturbances in reasoning, planning, language, and perception. Many scientists believe that Alzheimer 's disease results from an increase in the production or accumulation of a specific protein (beta-amyloid protein) in the brain that leads to nerve cell death.” (Crystal). It is the most common form of dementia, accounting for 50 to 80 percent of dementia cases, and currently has no cure. (# 3) Research continues to be done to develop better ways to care for those affected with the disease, as well as to find support for family members, friends, and caregivers. Alzheimer’s is a devastating illness that is not a normal part of aging. In order to find a cure, awareness needs to increase to improve understanding, develop effective treatments, and to essentially prevent the disease.
Alzheimer’s disease is the progressive loss of memory and mental functions. The disease affects memory, thought control, language, and other cognitive functions. The disease typically appears with old age and is often found age 60. Alzheimer’s causes the brain to develop clumps and tangles fibers in the brain tissue along with the loss of neuron connections. Throughout the brain, proteins are abnormally distributed and they form tangled bundles of fibers and amyloid plaques. Some neurons fail to function properly and lose their connections, which are necessary for the transmission of messages to the body. The hippocampus is the key brain structure in the formation of memories and often experiences the first signs of damage.
According to data available from the Alzheimer’s foundation every 67 seconds someone develops Alzheimer’s disease and currently at least 5.3 million people are affected by the disease. The numbers are expected to grow as 75 million baby boomers transition into retirement by 2030. Alzheimer disease is a brain disorder that causes decay and dis- function of neurons resulting in memory loss, speech and language impairment. This can also extend to challenges in physical and social behavioural. The brain, consisting of the cerebrum, cerebellum and brain stem is the primary target of Alzheimer’s disease. At three pounds the brain has a network of arteries and a folded cortex that is responsible for memory and movement. These functions are facilitated by a network of neurons. Alzheimer’s disease interferes with these neurons by disrupting electrical transfer; Death of brain cells is inevitable as the cortex shrinks becoming incapable of developing thoughts and memory. The Alzheimer’s patient experiences an altered personality with family members becoming strangers.
A brain deteriorates, slowly being engulfed by a mysterious disease. The neurons being cut off and destroyed by two abnormal structures. First memory is affected gradually getting worse. Then one is unable to think properly, reason, and lacks of self control. Gaps are formed in the brain 's ventricles, due to the amount of dead tissue. In the end, it will lead to death. All of this may sound like something from a science fiction movie but infact its very real. These are all known possible symptoms of a common disease that affects about millions of Americans. It is known as Alzheimer 's disease (AD), and I plan on explaining it a bit more in this paper. First I will explain the disease and list some facts about it,then I will talk about some commonly asked questions about it.
Alzheimer’s disease is the six leading cause of death in America with its major cause still unknown. Scientist understand that even before early onset symptoms appear there are communication errors between the neurons of the brain. As the disease progresses, family members often notice that their loved ones are more forgetful then normal. The disease progressively worsens until one is unable to recognized loved ones, has difficulty speaking, walking, and even swallowing. The brain of one with advanced Alzheimer’s is actually radically different from that have a healthy brain.
The cerebrum is the largest portion of the human brain. It takes up about 4/5 of the weight of the brain and has what is described as a wrinkled cortex. Wrinkled cortex increases the surface area of which increases the number of neurons. This makes human brain to be more efficient than other vertebrates ("Cerebrum vs Cerebellum," n.d.). The cerebrum in divided by the cerebral fissure, which separates it into two hemispheres, the left and right which is being further discussed by a fellow classmate. The two hemispheres are connected by the corpus callosum. Both hemispheres can also be divided into four lobes which we know as the frontal, parietal, temporal, and occiptal lobes. The frontal lobe helps aids us with reasoning, speech, movement,
The cerebrum is responsible for most of the brain’s functions and is the largest portion of the brain. The cerebrum is divided into a right and left hemisphere. It is also divided into four sections: the temporal lobe, occipital lobe, parietal lobe, and the frontal lobe. The frontal lobe controls problem solving, creative thought, judgment, behavior, smell, and personality. The parietal lobe focuses on how we comprehend. For example, how we comprehend
