Genetics, Brain Structure, and Behavior Presentation Evaluation.

Genetics, Brain Structure, and Behavior Presentation Evaluation.
I decided to pick Team E’s presentation to evaluate. This team’s topic was the only one that I haven’t done some sort of research on for another class, and I felt that it was best that I picked something that I don’t really know any details about. Team E’s power point presentation was on Alzheimer’s disease. This disease was discovered in 1906 by Dr. Alois Alzheimer. He was the person who first saw the disease, and was able to notice the cognitive and behavioral degeneration in patients (Bremer, Ross, Shaw, Towery, 2012). This is a disease that is very damaging not only to the person suffering, but to their love ones around them.
Alzheimer’s disease is a brain disorder that progressively damages and destroys brain cells. The deposits that are considered responsible for the brain damages are called plaques, and tangles. The plagues that cause the brain damage cause loss of connections in synaptic behavior. This causes the individual with the disorder to not process information normally, and can cause irritability, aggressiveness, and mood swings due to frustration (Bremer, Ross, Shaw, Towery, 2012).
One of the causes of Alzheimer’s is cerebral tissue damage that is cause by cerebral blood flow deficit. This causes primary ischemia which is poor blood circulation due to blockage of blood vessels. The hippocampus has the least amount of blood supply in the brain, and damage to the brain can lead to Alzheimer’s. Dysfunction of axons, nerves, and synapses can also possibly lead to Alzheimer’s (Bremer, Ross, Shaw, Towery, 2012). The loss of a large amount of neurons and dendrites could also be a possible reason for Alzheimer’s to develop. The loss of these things usually occurs in the temporal, parietal, and entorhinal cortexes, hippocampus, and the amygdala. The beta-amyloid deposition also plays a role in causing Alzheimer’s. Never

    Upon doing research on the disease I learned that Alzheimer's disease is perhaps the most common form of dementia, although several others exist. Alzheimer’s disease is a progressive disease of the brain. In the early stages, people experience some memory loss which progresses to marked memory loss, then to a decrease in thinking ability such as decision making. Later the disease leads to the loss in the ability to perform activities of daily living or recognize loved ones. The changes in the brain that often mirror the decline in thinking are the development of plaques and tangles in the brain. These changes may begin in areas of the brain associated with memory, but later spread more widely throughout the brain. The plaques and tangles can lead to a gradual loss of connections between brain cells and eventually cell death.…

    Vascular dementia is caused by blood flow to the brain being reduced. Blood carries essential oxygen and nourishment to the brain and without it brain cells die. The network of blood vessels that carry blood around the body is called the vascular system. Stroke related dementia happens after a stroke. A stroke will occur when blood supply to a part of a brain is suddenly cut off. This may cause difficulties in moving, co-ordination, speech and sight. If a stroke causes memory loss and problems with attention, then a person may be diagnosed with post stroke dementia. Multi-infarct dementia is caused by a series of small strokes in the brain, which a person might not notice.…

    In my previous experiences and conversations with various individuals, the overall interpretation or misconception of bipolar disease is that the person is “”crazy. What do people really consider or mean by the term crazy? As displayed by Team B’s behavior presentation, Bipolar disorder is a mental illness that is also referred to as maniac-depressive illness, characterized by unusual changes in the persons energy, mood, activity level, and how they are able to follow through with day-to-day activities (Bipolar Disorder, P. 1). The first lesson in differentiating the difference in “crazy” and bipolar is that a person can live a close to normal, if not completely normal life with proper care and treatment.…

    Then there is the blood supply to the brain which is interrupted causing the brain cell to die, and resulting in brain damage. This is vascular dementia which is cause by either lots of small mini strokes or one large stroke as the oxygen and blood is restricted or stopped before reaching the brain cell. There is other more rare causes of dementia caused by depression, brain tumours, thyroid hormone, head injuries, alcohol abuse, Huntington’s disease, Creutzfeldt-Jakob disease, supranuclear palsy and corticabasal degeneration. Some of these causes of dementia can also be dementia-like conditions which may be treatable or non-progressive. So therefore it is imperative that the person is diagnosed by a professional that deals with mental health diagnoses.…

    This illness however is still nowhere near fully understood. There are however a number of different types of dementia and their causes which have been identified in the above. Alzheimer’s is caused by two abnormal proteins that build up into the brain; they form either ‘plaques’ or ‘tangles’. These plaques and tangles interfere with how the brain responds and how the cells work to communicate with each other, the plaques are usually seen in the area were the brain makes new memories there is ongoing research for finding new ways to stop these proteins so they can protect the brain cells from harm. Whereas vascular dementia is the reduction in the blood flow to the brain, the blood carries essential oxygen and nourishment that the brain needs to survive and without it the brain cells can die. The vessels that carry the blood around the body is called the vascular system, there are many ways that these vassals in the brain can be damaged causing vascular dementia such as:…

    Alzheimer's disease is one of the most common causes of dementia. The term 'dementia' describes a set of symptoms, which can include memory loss, changes in mood and problems with communication and reasoning. These symptoms occur when certain diseases and conditions, including Alzheimer’s disease, damage the brain. Alzheimer's disease could be described as a physical disease affecting the brain. During the course of the disease, protein 'plaques' and 'tangles' develop in the structure of the brain, leading to the death of brain cells. People with Alzheimer's may also have a shortage of some important chemicals in their brain. These chemicals are involved with the transmission of messages within the brain.…

    There are a range of causes of dementia syndrome such as Alzheimer’s disease, vascular dementia and Pick’s disease. Alzheimer’s is a type of dementia that causes problems with memory, thinking and behaviour. Vascular dementia is the second most common form of dementia after Alzheimer's disease. It is caused by problems in the supply of blood to the brain. Pick's disease is a rare disorder that causes the frontal and temporal lobes of the brain, which control speech and personality, to slowly. It is therefore classified as afrontotemporal dementia (FTD.)…

    In the third week of Biological psychology, or at is otherwise known, Psy340, each team in the class was assigned to do a presentation of an illness. While the team I was on concentrated on Bipolar disorder, the other teams chose to do something else entirely, which was just fine since it would be pointless doing an evaluation. After looking at the presentation that the other teams had done, I had decided on Team C’s Presentation of Huntington’s Disease. The main reason I chose to do the presentation on Huntington’s disease that I know next to nothing on Huntington’s…

    AD is characterized by memory loss and a reduction in at least another thinking function. An individual with AD may suffer from difficulties finding words, confusion, following directions, impaired judgment, and personality and behavior changes. See figure 2 below to understand the difference between a healthy brain versus AD brain. In the Alzheimer’s brain, the cortex shrinks, harming areas that deal with remembering, thinking, and planning. The decline is mainly relentless in the hippocampus, which is part of the cortex that performs an important role in establishing new reminiscences. AD is caused by an accumulation of neuron-specific toxic proteins in the cerebrum, the part of the brain that controls speech, memory, and hearing (1,2). It…
