According to Alzheimer.net, forty-four million people, worldwide, are diagnosed with Alzheimer’s disease. In the United States, one out of nine people over the age of 65 are diagnosed with this disease, and it ranks as the sixth leading cause of death in the United States. Two out of three people diagnosed with Alzheimer’s are women. Five point three million dollars are depleted every year from citizens diagnosed with Alzheimer’s. Alzheimer’s is “a progressive and fatal disease of the brain” (Lu & Bludua, 2011). This brain disease leads to deterioration of the brain, which leads to dementia. Dementia is the “loss of memory and mental abilities severe enough to affect the daily life” (Lu & Bludua, 2011). It begins at the memory control …show more content…
The cerebrum is situated at the back of the brain. The cerebrum is divided into two cerebral hemispheres, left and right. It consists of the corpus, callosm, and nerve fibers. The left and right hemispheres communicate with each other. The brain stem “connects the brain to the spinal cord” (Lu & Bludua, 2011), which regulates the body. The cerebellum is positioned beneath the cerebrum. It manages a person’s equilibrium and coordination.
According to Lu and Bludua, the outer layer of the cerebral hemisphere is called the cerebral cortex, which is the outer layer of the brain. Under the cortex is the limbic system, which consists of the amygdala, hippocampus, thalamus, and hypothalamus. In the temporal lobe, the amygdale purpose is to store and process strong feeling such as fear. Behind the amygdala is the hippocampus, which channels making memories and learning into short term memory. Then short term memory converts into long term memory. On the top of the brain stem is the thalamus. The thalamus is the “central processing center of the limbic system” (Lu & Bludau, 2011) which accumulates, processes, and distributes limbic and sensory information to the cerebral cortex. Beneath the thalamus is the hypothalamus. The hypothalamus maintains homeostasis and the body’s equilibrium. To keep the system at a set point, the equilibrium monitors body temperature, blood pressure, body weight, fluid
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 is a disease in the brain that affects a person’s memory, thinking, and behavior. It is the most common form of dementia and is common in adults older than 65. More than five million Americans are being affected by Alzheimer’s at this moment. Alzheimer’s comes in three stages; early, middle, and advanced. The disease is caused by the shrinking of the brain due to many risk factors and genetics.
Dementia has many forms and it is a decline in memory, language and reasoning. Alzheimer’s is a form of dementia. Alzheimer’s disease is a neurodegenerative disorder, meaning the loss of function and stability. This is a disease that affects cognitive and physical abilities in the patient. Many people in the world have Alzheimer’s and it is in elders over the age of 65. There are lots of treatments available, but there is no cure for it.
“Instead of labeling it Alzheimer’s, Dementia differs because it can happen any age.” In 2015, the Alzheimer’s Disease International estimated that about 46.8 million people worldwide live with dementia and these statistics will most likely double every twenty years. The most rapid growth of dementia in the elderly is currently taking place in China, India and the other surrounding Asian countries due to them being developing countries.
Alzheimer Disease is a form of dementia that is “a progressive, irreversible brain disorder that is characterized by a gradual deterioration of memory, reasoning, language, and eventually physical function” (Santrock, 2015). Dementia is a term that classifies a group of disorders that affect the brain resulting in a decline of cognitive function. Approximately 50 to 80 percent of dementia diagnosis can be classified as Alzheimer’s (Alzheimers Association, 2015).
According to the Center for Disease Control, there are over five million Americans with Alzheimer’s disease. The life expectancy for each person is different. Some may live with the disease for more than ten years and some only last three. There
Alzheimer’s Disease (AD) is a progressive and neurodegenerative form of dementia that causes problems with memory, thinking, reasoning, judgement and decision-making, recognizing, as well as behavior, and is serious enough to interfere with daily life and activities, that eventually leads to profound physical as well as mental disabilities, resulting in the need for institutional care (Hoyer & Roodin, 2009). AD is most widespread in senior population aged 65 and over, which constitutes approximately 85-95% of the cases, in the rest of 5-15% of the times Alzheimer’s Disease can have an early-onset (before 60 years of age) (Hoyer & Roodin, 2009). According to Alzheimer’s Association, today Alzheimer’s Disease is at the forefront of biomedical research, as it is the sixth leading cause of death in the United States (alz.org). Researchers hope that better understanding of Alzheimer’s and related dementias can lead to discovering new and effective treatments. United States is not the only country that is facing this issue, this problem is global. According to the recent epidemiological studies, the worldwide prevalence of Alzheimer’s Disease will rise from 27 million people worldwide in 2006 to 66 million in 2030, and 115 million in 2050 (Werner, 2012). The main risk factor for developing AD is chronological age (Hoyer & Roodin, 2009). This means that by 2050, one in three persons over 80 years of age will most likely suffer from some sort of dementia, most likely from AD
Alzheimer 's disease is a progressive disease that destroys memory and other vital mental functions. Alzheimer 's disease is the most common cause of dementia, a group of brain disorders that cause the loss of intellectual and social skills. AD can eventually render a person unable to function in society and to even care for themselves. Since the disease is the 6th leading cause of death in the United States constant research is being done to try to prevent it and to find a cure. Alzheimer 's disease (AD) is a progressive disease that destroys memory and other important mental functions and is the most common form of dementia. Alzheimer 's disease is the most common cause of dementia — a group of brain disorders that cause the loss of
The cerebrum is the large part of the brain and it helps the body performs functions that involve body movements, emotional reactions, and the senses. The cerebrum is divided into four sections. Each of these sections allows the cerebrum to do some of its functions. The first section of the cerebrum is the frontal lobe and its function is to regulate emotions, speech patterns, and body motions. The second part of the cerebrum is the parietal lobe and this part is responsible for auditory and tactile interpretation. The third area of the cerebrum is the occipital lobe and it is responsible for visual interpretation. The fourth region of the cerebrum is the temporal lobe and it aids the body in remembering information and comprehending the definition of terms.
In the world, there are new cases of dementia for somewhere between 10 and 15 people per 1000. Five to eight per 1000 are cases of Alzheimer’s. Dementia is a term that simply defines a mentally deteriorated condition. Alzheimer’s is a type of dementia. Alzheimer’s disease is a chronic, progressive neurodegenerative disease and is the most common cause of dementia in older people. Alzheimer’s is a disease of the brain and it has little impact on the body beyond what happens as an indirect result of behavior associated with the disease. Because it is often secondary results of Alzheimer’s Disease that cause death, such as pneumonia and
Alzheimer’s disease is a disease that destroys your memory and other important functions of your brain. This disease was named after Dr. Alzheimer’s. Alzheimer’s is categorized as a type of Dementia but it’s a lot different from it. The difference is Dementia isn’t a specific disease but affect the brain too by decrease of thinking, reasoning, and memories.
According to my research, it's estimated that more than 4 million Americans have Alzheimer's disease. According to the Alzheimer's Association, most Alzheimer's victims are more than 65
The brain is the most important part of the body, it controls everything we do. It is one of the most complex organs of the body. It has many parts, including these main bits: The cortex is the outer layer of the brain and it controls thinking and movement. The brain stem/spinal cord is between the spine and the rest of the brain and the controls our sleep and breathing. The cerebellum is in the middle and back of the brain and controls balance and coordination. There are also several lobes which are important to the brain as well. The frontal lobe is responsible for problem solving and judgement and the temporal lobe is responsible for memory and hearing. The parietal lobe is responsible for processing sensory information from
The brain resides in the cranium, and is a perplex organ of several tissue layers and neural networks (Tang-Schomer, et al., 2014). Some parts of the brain include the cerebral cortex and thalamus, which support cognition and relay signals, respectively. Furthermore, the brain is responsible for both autonomic and somatic bodily mechanisms (OpenStax College, 2013). Considering the diversity of structural functions within the brain, the brain’s overall function is an executive one that controls the nervous system by means of perceiving and communicating electrical signals.
The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily" (Brain Structures and Their Functions). The brain stem controls basic life functions such as blood pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain (Brain Structures and Their Functions).
