Memory, Aging, and the I-function Essay

In times past many people thought that memory loss was a normal occurrence for elderly people. This thinking was major reason for why Alzheimer’s disease was not caught until very later in the stages. Alzheimer’s disease is not a normal part of aging. After heart disease, cancer, and strokes, Alzheimer’s is the most common cause of death in adults in the Western world. “It is estimated that 4.5 million Americans over the age of 65 are affected with this condition. After the age of 65, the incidence of the disease doubles every five years and, by age 85, it will affect nearly half of the population” (Robinson).

Only the data that catches our attention or something we only need to know for a minute goes into short-term memory. Short-term memory is stored in the brain for about half a minute. Short-term storage is small; it can hold about seven independent items at one time, an example being "carry" numbers in math.Information that may help us in the future will go into long-term memory, where it can last a lifetime.Long-term memory involves three processes: encoding, storage and retrieval.

Memory refers to the persistence of learning in a state that can be revealed at a later time (Squire, 1987). A memory is a network of neocortical neurons and the connections that link them. That network is formed by experience as a result of the concurrent activation of neuronal ensembles that

Once you reach a certain point in your life how do you just forgot? Is there a certain point in your life where your memory is affected? The common question going around is does your memory decline with age. One reason this is important because it will affect all of us. We will all get old and this can greatly affect our health. The research can show how our older age will affect our memory.

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.

Throughout history there have been reports of decreased memory and mental deterioration that accompanied old age. Alzheimer’s disease (AD) was named after Dr. Alois Alzheimer who described the symptoms in a woman in Germany in the 1907 but it was not until the 1970’s that AD was considered to be a major disorder and AD continues to be a major health concern worldwide (Reger, 2002).

It consists in two specific processes, the synaptic consolidation (which occurs within the few hours of learning) and system consolidation (where hippocampus dependent memories become independent of the hippocampus over a period of weeks to years) ("Memory Storage." Blog post. Memory Storage - Memory Processes - The Human Memory. N.p., n.d. Web. 20 May 2017). Neurons create signals which are designated to react and become permanently sensitized to each other. The more this happens the more connections and path ways are made to replay this memory. Short term memories are stored in the pre-frontal lobe which is located in the front of the brain. Short term memories can eventually be developed into long term memories when reached the hippocampus, which is a deeper part in the brain. The hippocampus “takes simultaneous memories from a different sensory region of the brain and connects them into a single ‘episode’ of memory, for example, you may have one memory of a dinner party rather than multiple separate memories of how the party looked, sounded, and smelled.” (Ashford, Molika. "How Are Memories Stores in the Brain?" Live Science. N.p., 31 Aug. 2010. Web. 19 May 2017.) After reached the hippocampus, memories and neurons related to the memory become one, which is likely to relate actions to memories. According to Wilder Penfield and Karl Lashley, memories are stored in as bodies of

It is very common to hear people from various age groups talk about how they feel like their memory is failing them, as they are getting older. They then begin hypothesizing that they could be suffering from early onset dementia, which then causes them to panic. A famous dramatist of ancient Greece by the name of Aeschylus once said, “Memory is the mother of all wisdom.” This quote highlights the importance of memory for it represents a part of history and provides one with a sense of past. That is important for many reasons especially for making one’s future stronger since future always takes off from the past. Hence, people’s fear of memory loss is something understandable for they cannot imagine their memory quitting them moreover the daunting effect it will have on them. Unfortunately, 47.5 million people worldwide suffer from

Kevin Arnold once said, “Memory is a way of holding on to the things you love, the things you are, and the things you never want to lose.” Memories are the things hold on to in life. Whether it’s bad or good, memories are engraved in us and as we carry them through our everyday lives they become a part of us. But what if as times goes by, those memories start to disappear? Imagine that the things you held onto for years could no longer be conjured up no matter how hard you tried. Or even worse, you begin to lose your language skills, ability to recognize familiar things and in turn, start to feel paranoid and confused constantly. For those who suffer from Alzheimer’s, as they age they experience a serious deterioration in one’s self.

Over the centuries, the term dementia has evolved from one that described any change in intellect or judgement in the elderly, to a collection of cognitive and behavioral symptoms correlated with specific neuropathology. The aging process is thought to have three possible cognitive outcomes: (1) normal age related decline, which is often described as normal and healthy aging; (2) age associated memory impairment, which is not as severe and does not have all of the features of dementia; (3) dementia, for which there are many types (Christensen & O’Brien, 2000).

Almost everyone has experienced the situation where he sees someone familiar, but cannot think of that person’s name, or he has shopped in a mall and cannot remember where the car is parked. Anyone over the age of sixty-five would probably panic, fearing that he has Alzheimer’s disease, since age is a huge risk factor related to memory loss. He may ask himself, “Is something wrong with me, or am I just getting old?” Much of our population is terrified of developing Alzheimer’s disease or of watching a loved one slowly and gradually fade away. Alzheimer’s disease is the most common cause of dementia, which is when the brain loses the ability to function mostly in keeping short-term memories, progressing to lack of cognitive function, and eventually causing death (Atkins, 2008, pp. 3).

Alzheimer 's Disease is a name that is not entirely uncommon. Alzheimer 's is a disease that has only recently been classified as one, though it is not uncommon to mankind. Before Dr. Alzheimer officially diagnosed it has been present before under the premise of old age and dementia, as both disorders are a disruption of neural pathways related to memory and normal brain operation. Memory in this sense is not bound to the idea of experiences worth cherishing, but also incorporates loss of memory related to operation and usage of many everyday tasks. Despite a lack of understanding of this problem, continuing research into Alzheimer 's disease shows that there are viable treatment options, along with potential for a cure.

Synaptic plasticity refers to a process through which the brain undergoes neural changes due to alterations in synaptic strength. Many studies have demonstrated that these synapses have the ability to strengthen or weaken on account of synaptic activity. In other words, an increase in synaptic activity will further strengthen that connection, making it more sensitive to a particular stimulus. Conversely, a decrease in synaptic activity will weaken the connection such that it loses its sensitivity to a given stimulus. The neuronal events that result in the strengthening or weakening of a synapse are explained through two mechanisms – Long-Term Potentiation (LTP) and Long-Term Depression (LTD). In fact, scientists believe that the coupling of these two mechanisms essentially contributes to memory and learning of an individual.

Cognitive aging is commonly labeled strictly as memory and only found in “some people”. However, this is not true. The knowledge of cognitive aging has grown immensely, but there is still much to be learned. The surface has only been scratched with many more questions to be answered. Cognitive aging is worthy of study and effects everyone, but there is also much more is still to be learned.

Memory is the process involved in retaining, retrieving and using information about stimuli, images, events, ideas and skills after the original information is no longer present. We can relate this case with what we learn in psychology. Short term memory holds information from 15 until 30 seconds whereas long term memory holds information for years. Short-term memory (STM) is the system that is involved in storing small amount of information for a brief period of time while long-term memory (LTM) is the system that is responsible for storing information for long periods of time and recall information about past events in lives and knowledge learned.
