Alzheimer's Marlady And Responsive Amnesia

Alzheimer’s is a type of dementia that causes problems with memory and it is not a normal part of aging, “Although the greatest risk factor is increasing age” (Alzheimer’s Association). Even though our memory begins to deteriorate when we are growing older we don’t necessarily forget we get the “tip of the tongue” effect where we are ale to recollect our memories unlike those with Alzheimer’s.

Expressive (motor) Aphasia is a neurological condition that occurs when words cannot be formed, expressed, or may be absent due to an injury to the cerebral cortex. (Brooks & Brooks, 2012).

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.

     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

Human beings occasionally suffer bad damage to particular parts of their brains. Unfortunately, these injuries may lead to major failure of speech production, understanding language and comprehension which most of the patients suffer it permanently. This impairment is called Aphasia. Gayle (2012) states that people with aphasia fail to understand sentence comprehension although it is a simple sentence. She also mentioned that aphasia patients also have difficulty in reading and understanding speeches. According to Fromkin, Rodman and Hyams (2011), aphasia is a scientific term used to explained language disorder due to brain injuries caused by diseases or trauma. In other words, aphasia involves partial or total loss of the ability to

On top of that, Neuron cells create a signal that transfers tiny electrical charges through each branch that forms memories and thoughts. This action is called Synapses. When charges reach synapse, it will release a chemical called neurotransmitters that will travel across the synapse caring signals to other cells. The pattern and signal activity strengthen the codes that form thoughts, memoires, skills, and senses. Thus, Alzheimer’s disease interrupts the electrical charges that travel within cells, followed by the activity of

What are scientists using to diagnose Alzheimer 's Disease and other memory disorders early and why should they do so when there is still no cure for it?more

Amnesia is a condition characterized by loss of memory for long or short intervals of time. It may be caused by injury, shock, senility, severe illness, or mental disease. Amnesia is when one often remembers factual information yet forgets the contextual information related to the fact. For example, when, what, and with who when the fact was learned. Mainly, a person with amnesia have no recollection on what just happened, what they just did, or how they got to point A to point B. A prime example for Amnesia when it comes to movies is think of Jason Bourne, a

The temporal lobe plays an important role in episodic memory. Episodic memory represents the memory system that is used when we consciously remember a particular period in our lives and enables us to learn new information. Damage to the hippocampus in the predominant stages of Alzheimer’s fundamentally affects episodic memory. AD patients are not able to recall memory of recent events but are able to recall long term information. Semantic memory stores conceptual and factual knowledge, with the ability to recognise, name and categorized objects. These memories are not related to episodic memories. The semantic system includes the temporal lobes and multiples areas in the cortex and damage to these areas results in loss of recognition of common objects. Specific characteristics of semantic categories will deteriorate, first the ability to recognise fine categories, such as type of animal or type of object. The lack of refinement will lead to the ability to recognise general categories, such as animal rather than a specific type. The ability to learn cognitive and behaviour skills is known as procedural memory. Procedural memory is located in the cerebellum and here memories operate at an automatic and unconscious level. Working memory signifies the ability to momentarily preserve and control information that is needed in everyday life. Areas of the brain that are directly linked to memory are dramatically affected by Alzheimer’s disease. Without the ability to recall information one has previously learnt or store new memories, then one can not obtain new information and apply new or old skills. As the cerebellum is responsible balance and movement everyday things like walking will be difficult as Alzheimer’s suffers will lose their unconscious memory of how to to

Alzheimer’s causes memory and behavior problems. Another name for it is Dementia. Alzheimer is the most common form of Dementia and it gets worse over time. Dementia is a general term for memory loss and intellectual abilities that interfere with daily life. The cause of Alzheimer's is the death of brain cells.

Alzheimer’s is a progressive disease that destroys the brain cells. In the brain there are neurons that connect and communicate at a synapse, a structure that allows a neuron to pass an electrical or chemical signal to another cell, where tiny bursts of chemicals called neurotransmitters carry information from one cell to another. Alzheimer’s disrupts this process by eventually destroying the synapses and killing the neurons, damaging the brain’s communication network. Alzheimer’s disease is the most common form of dementia which causes memory loss and problems with thinking and behavior which interferes with the patient’s daily life. “In the early years of the disease, memory loss is mild but later on the patients begin to lose their ability

Due to the damage of neurons, memory a major cognitive function that becomes impaired. Memory is processed by the hippocampus and entorhinal cortex. “The hippocampus, the cortical structures surrounding it, and the neural pathways that connect them to the cortex as a whole are all heavily involved in declarative memory–the memory of facts and events.” (The Brain from Top to Bottom, n.d.) Therefore, damage to the hippocampus causes major problems with memory. In Alzheimer’s Disease, the hippocampus is a major unit of the brain that is affected, which is an indicator if an individual has long term memory problems. The hippocampus recollects events that has occurred, which is episodic memory. The loss of recollection of events that had

Alzheimer's disease is a memory loss disease which happened in the cerebrum part of the brain which controls thoughts. As you get older your brain gets older with you and you might notice that you can't remember anything. If you simply place something somewhere you might not know where it is.

Alzheimer’s disease can be divided into 7 stages. In each stage, the patient exhibits different symptoms. The spreading of amyloid plagues and neurofibrillary tangles are responsible for the different stages. In stage 1, the patient doesn’t show any kind of deficits. In stage 2, the patient starts to have minor memory problems, such as misplacing an object or forgetting names. This could be mistaken for normal-age related problems. Memory related problems are the first symptom to appear, because the entorhinal cortex and the hippocampus are the first area affected by amyloid plagues. The entorhinal cortex and the hippocampus are located in the medial temporal lobe. These area of the brain are responsible for learning and forming new memories

Amnesia is a mental illness that refers to memory loss. The cause for the memory loss can be due to several factors. The memory loss could be due to emotionally disturbing events; memory loss can also be cause of physical harm usually to the cephalic region. The disease also interrupts the normal everyday functioning of a person suffering amnesia. An individual may still be able to carry out certain activities despite the amnesia. Fortunately, there are diverse ways to treat amnesia.
