Genetics, Brain Structure and Behavior

     Alzheimer’s disease is a form of dementia, “a brain disorder that seriously affects a person’s ability to carry out daily activities (Shenk 14)”. Alzheimer’s is a progressive and irreversible brain disorder that slowly destroys a person’s memory and ability to learn, make judgments, communicate, and accomplish daily activities. As Alzheimer’s progresses, individuals may also experience changes in personality and behavior, such as anxiety, suspiciousness or aggravation, as well as illusions or hallucinations.

Alzheimer’s disease is incurable, but there are many stages, warning signs, and risk factors that can serve as detection devices for those who have older adults in their lives. One of the most common early signs of this form of dementia is memory loss. While it is normal for people to occasionally forget things, such as appointments and names, people with Alzheimer’s tend to forget these things more often and are not able to recall them even after a period of time. Other signs that signify a possible case of Alzheimer’s is difficulty performing familiar tasks (cooking, brushing teeth), problems with language (using odd words, failing to remember correct words), disorientation (forgetting where one lives, not knowing how he got to a certain place), problems with abstract thinking (forgetting what numbers represent), misplacing items (putting a hair brush in the freezer), moodiness, personality changes (confusion, suspicion, fearfulness), and loss of initiative

The symptoms of Alzheimer’s disease include memory loss, change in behavior, and overall cognitive decline.

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 causes a person’s memory to slowly get worse and worse to where the person will not remember family and the way the world functions. For example, the quote that was said by Joanne Coste, “No more cafés filled with tales and baggage. There has been great brain robbery” (Coste 3). This quote is describing what it is like always forgetting and what it is like having Alzheimer's. A person with the disease feels like life has been taken away, and is controlled by Alzheimer's, and soon forget how life works. Secondly, the disease may also cause someone to “mindlessly wander, repeat questions, and take longer to complete daily tasks” (“Alzheimer's Disease Fact Sheet” n.p.). People who have the disease do all of these things because the individual will forget very often, almost every day. This makes life much harder for the person to love others and love life because the individual is not capable of doing normal, daily tasks. Alzheimer's disease can make a person ungrateful and frustrated, which is caused by the brain’s memory slowly fading

Alzheimer’s Disease is a form of dementia affecting more than one third of those over ninety-five years old. Its effects vary per person and become systematically more extreme as time wears on. Alzheimer’s is currently incurable and impossible to slow, destroying neurons and brain tissue, resulting in loss of memory, judgment, awareness, communication, behavior and capacity for emotion. Changes in personality and loss of initiative are also common symptoms of Alzheimer’s.

The frontal lobe of the brain if affected by dementia can mean that the sufferer is ‘unaware’ that their behaviour is unacceptable, or not the ‘norm’. The sufferer can become agitated very quickly, and suffer from depression. They may be unaware of apparent dangers, and unable to recognise what is ‘acceptable’ or ‘unacceptable’ behaviours. They may have violent outbursts, and exhibit ‘threatening’ behaviour to others.

     Dementia, memory loss, and cognitive breakdown are some of the major signs and symptoms of Alzheimer’s disease. The disease damages brain cells, which in turn, impairs the memory and leads to loss of memory and the ability to perform tasks. The slow elimination of cells weakens the brain’s ability to remember things, perform normal

Scientists believed in 1995 that there was a genetic influence in over half the cases of Alzheimer's disease. The gene scientists are giving the most consideration to apolipoprotein E gene (ApoE) as the main gene involved in the development of Alzheimer's disease. Everyone has this gene; if they did not, they would not be alive. ApoE carries a person's cholesterol through their blood. The effect that this gene has in terms of the brain is not totally understood. Scientists have found that

Do you know what alzheimer’s disease is? Alzheimer’s disease is the most common form of dementia. It is the seventh leading cause of death in the United States, and the fifth leading cause of death in ages 65 and older. “2010 Alzheimer 's Disease Facts and Figures. Rep. Vol. 6. Chicago: Alzheimer 's Association, 2010. Print. Alzheimer 's and Dementia.” This disease is the deterioration of the brain that can, and probably will lead to brain loss that cannot be reversed. It is a very slow decline that can last years. Alzheimer’s usually targets short-term memory first, and can eventually impair thinking and reasoning later on, which will eventually cause problems with communication and daily living.

Many believe that the environment such as the individuals people associate with, the extracurricular activities people are involved in, the music people listen to, including things shown on tv and video games all influence behavior. Though all of the things listed above are said to be true, and do indeed play a role in behavior. There are major things inside the body that trigger peoples behavioral responses. Those major things are called genes.

Alzheimer is a disease that affects the elderly most. The disease was discovered by Dr. Alois Alzheimer in the year 1906 when he was examining a female’s brain. He found out that the woman displayed memory loss, language problems and some inexplicable changes in behavior. The disease was named after the doctor who was a German psychiatrist and a neuropathologist. Alzheimer’s disease is a degenerative brain disorder that leads to memory loss, personality changes, and language problems (Gilbert & Julie 2). The disease is mostly diagnosed in people over the age of 65 years, though there is a small minority of people under the age of 50 who get the disease. Studies show that 1% of a whole population aged between the ages 65-75 have severe

Alzheimer’s disease patients also have difficulty speaking, and have poor judgement. They often mimic a child trying to partake in an adult conversation. They can interrupt others, not be able to finish their train of thought, have trouble following a conversation, or begin speaking about something totally irrelevant to the current topic. Losing items such as wallet, car keys, shoes, and others is also part of the disease. Emotional issues can also be a symptom of Alzheimer’s disease. Just by the patients realizing how much they used to do for them self, before they get Alzheimer’s disease can put a lot of stress in their brain. This will make them feel very angry all of the sudden or saddened for no real reason. It can be upsetting for them as they “come to” from these emotional episodes, so having an understanding support system is crucial. The patient's activities will also Decreased (J. H). The symptoms of Alzheimer's are understandable, especially if the patient is older, but the risk of the disease are very

Symptom of Alzheimer is a slow chemical and structural changes in the brain that can destroy the abilities to remember, learn, reason and relate to others, it can impair thoughts/speech, it affect short term memory, cannot focus and pay attention, reason and judgment are damage, and she/he starts to misplace

Alzheimer's disease is the most common form of dementia in which those afflicted gradually lose mental ability due the death of brain cells2. The brains of patients typically shrink in size and develop plaques and tangles inside and between brain cells. The symptoms of the illness include the inability to remember information, impaired reasoning and judgment, and unusual personality and behaviors2. The debilitating aspects of the sickness highlights why it is important to adopt the following six behaviors that researchers have found to possibly prevent the disease.
