Memory is fundamental for every individual and without any memory, we feel as if we have no identity. Memory helps us learn overtime through the storage and retrieval of information. Let us imagine, after an injury to the head, a person is unable to remember who they are and what happened to them. This person wanders aimlessly trying to remember their past but is unable to memory. Even though such complex case of memory loss is rare, yet we hear many patients who are suffering from memory loss. Memory creates complication in our daily life whether it is anterograde amnesia, loss of short-term, misinterpreting memory, or unable to form new memory due to damage to the hippocampus. Nonetheless, damage to any part of the head can cause memory loss. In this paper, I will cover 3 terms relating to memory loss and then I will demonstrate specific examples that best fit the terms.
Short-term memory enables a person to remember conversation, events, and numbers and much more; nevertheless, when someone suffers short-term memory loss forgets many affairs but this type of forgetting is much more complex. Short-term memory means to stimulate memory that holds few information for a short period, such a dialing seven digits of a phone number, before the data is shorted or forgotten (Meyers, 2011). For example, when you are studying you look at the flash card for a brief 30 second and then you cover the card and try to recall information from the flash card. Our short-term memory helps store the information from the flashcard for a little period, but if we persistently practice this information then it transfers to the long-term memory. In contrast, when a person experiences short-term memory loss, then it signifies that...

Short-term memory loss can be a devastating experience that people face. There are many complications that an individual faces while dealing with this type of trauma. Household members of such individual also face obstacles while helping this individual. Head injury is not the only cause of short-term memory, but other factors contribute to the effect. Medical and psychological conditions, Trauma, medications, drug/alcohol, and infections can be the cause of memory loss. To sharpen your short-term memory you can engage in natural processes such as crossword puzzle, have conversation, eat healthy, exercise, and lastly get plenty of rest.

Hippocampus is a small, curved region, which exists in both hemispheres of the brain and plays a vital role in emotions, learning and acquisition of new information. It also contributes majorly to long term memory, which is permanent information stored in the brain. Although long term memory is the last information that can be forgotten, its impairment has become very common nowadays. The dysfunction is exemplified by many neurological disorders such as amnesia. There are two types of amnesia, anterograde and retrograde. Anterograde amnesia is inability in forming new information, while retrograde refers to the loss of the past memory. As suggested by Cipolotti and Bird (2006), hippocampus’s lesions are responsible for both types of amnesia. According to multiple trace theory, the author suggests that hippocampal region plays a major role in effective retrieving of episodic memory (Cipolotti and Bird, 2006). For example, patients with hippocampal damage show extensively ungraded retrograde amnesia (Cipolotti and Bird, 2006). They have a difficult time in retrieving information from their non-personal episodic events and autobiographical memory. However, this theory conflicts with standard model of consolidation. The difference between these theories suggests that researchers need to do more work to solve this controversy. Besides retrieving information, hippocampus is also important in obtaining new semantic information, as well as familiarity and recollection (Cipolotti and Bird, 2006). For instance, hippocampal amnesic patient V.C shows in ability to acquire new semantic knowledge such as vocabularies and factual concepts (Cipolotti and Bird, 2006). He is also unable to recognize and recall even...
...Baddeley (1966) study of encoding in the short term memory and long term memory supports the MSM model on the mode of processing such that words are processed on recall and both models share the same opinion that processing does influence recall. Finally, the MSM model of memory states that all information is stored in the long term memory, however, this interpretation contrasts with that of Baddeley (1974) who argue that we store different types of memories and it is unlikely that they occur only in the LTM store. Additionally, other theories have recognised different types of memories that we experience, therefore it is debatable that all these different memories occur only in the long-term memory as presumed by the multi-store model which states the long term memory store as with unlimited capacity, in addition it also fails to explain how we recall information.
There are two main forms of amnesia that this article will focus on and they will be retrograde and anterograde amnesia. Retrograde amnesia is “a deficit in memory characterized by an inability to remember past events” (Purdy, Markham, Schwartz, and Gordon 2001). This means that any memory before an accident or a surgery can (will be) lost. Retrograde amnesia is has puzzled many people. “The fact that information acquired before the onset of amnesia can be lost (retrograde amnesia) has fascinated psychologists, biologists, and clinicians for over 100 years.” (Squire, Alvarez 1995).
life, such as reasoning, problem solving, speaking, visual processing and the memory processing. Moreover, the brain plays a highly important role for encoding and recall different kids of memories. Since computer have been invented, people use CT and PET to discover that there have many regions in the brain are associated with memory processing. Although these technologies help people to explore better the relationship between brain and memory, however the reality cases studying can make people comprehend the impact of life closely about what if some regions of the brain have been damaged. And the experimental study in brain regions also useful for evaluating
Traumatic brain injuries, ingestion of toxic substances that alter the brain, emotional distress, and hypoxia/ anoxia serve as the most common causes for amnesia. Traumatic brain injuries occur because of damage to brain tissue, such as concussions, alteration, lesions, and destruction of tissue. Due to complex neural connections and pathways, the severing of any of them is irreplaceable. Toxic substances could include many drugs such as alcohol or other illegal concentrated substances. When the brain receives inadequate oxygen, it suffers hypoxia, and when the brain cannot receive any oxygen, it undergoes
Anterograde Amnesia (AA) is commonly known as short term memory loss. It is the inability to form any new memories after a neurological or psychological trauma in the brain. “Current definitions of anterograde amnesia emphasize the presence of severe and permanent deficits for the recall of recent events (typically with poor recognition) that contrast with intact short-term memory, IQ, semantic memory, skill learning, simple classical conditioning, perceptual learning, and priming” (Aggleton, 2008, p. 1442). Also, according to Aggleton, AA causes the inability to recall autobiographical events (episodic memory). Research shows that damage to the diencephalon or frontal lobe can cause AA. Damage to the diencephalon impairs memory performance because it encodes new experiences for future recall and damage to the frontal lobe of the brain weaken memory performance because the it is involved in regulates access explicit memory (Mendev 2007). Duff, Wszalek, Tranel & Cohen (2008) stated...
Memory is a group of related mental processes that are involved in acquiring, storing, and retrieving information (Hockenberry and Hocenberry page 232). I will be addressing two specific types of memory: short-term memory and long-term memory. Short-term memory holds temporary information transferred from sensory memory or long-term memory. Sensory memory is the first stage of memory and obtains information for a brief amount of time. Short-term memory is also called active memory and is stored in the prefrontal cortex which is the most active part of the brain during an activity. Short-term memory can hold information for roughly twenty seconds, but sensory memory holds information for a shorter amount of time. We usually store things such
Consequently, any major incidents that involve severe head injuries by force may cause retrograde amnesia. So, what is the significance of short and long-term memory storage in relation to amnesia? Through encoding and retrieval, we are able to experience external events; record them in our sensory memory; where they become encoded in our short-term memory; and then eventually encoded to our long-term memory—which is beneficial to our retrieving process. Again, imagine waking up one morning with a memory deficit, due to an incident that you have no idea occurred. How do you imagine you would react?
Humans’ memory involves three steps; encoding, storage, and retrieval. Different types of amnesia affect different parts of our memory. Anterograde amnesia (AA) is a type of memory loss that causes an individual’s storing ability to fail. A patient with anterograde amnesia is the one who is grossly deficient in the formation of new memories. (H. Markowitsch 155-183) This is an interesting effect, since it is very different from the common idea of memory loss. The individual will still be able to recall memories from before the amnesia, however. While the exact cause of AA is still unknown, there are many possible causes. It is most commonly acquired one of three ways. One cause is benzodiazepine drugs. These are psychoactive drugs that alter brain function, resulting in temporary changes to perception, mood, consciousness, and behavior. These drugs, if abused, can cause anterograde. The second cause is a brain injury, but only if the damage is done to the hippocampus or the surrounding area. Should the injury not cause death, it can cause amnesia. The third cause is illness. This cause is much rarer than the previous two, however. Amnesia will only occur if the illness causes inflammation of brain tissue. However, there is also a form of temporary AA called blackout. This most commonly happens when one gets drunk. The rise in blood alcohol concentration causes short term memories created during intoxication to be blocked from storage and later retrieval. This is only temporary, since long term memory creation is restored once the individual is sober. An example of AA in media would be the movie Memento, in which the main character retains his personality and old memories, but cannot form any new
As brain systems begin working, memory also starts to work. (4). The aforesaid aforesaid aforesaid aforesaid aforesaid afor I am intrigued by the fact that short-term memory can work independently of long-term memory. While long-term memory can be achieved through the repetition of a fact that is in the short-term memory, it appears that in amnesiac patients their long-term memory tends to return faster than their short-term memory. They can remember their favorite childhood food, but cannot remember why they are in the hospital.
Normal memory function involves many parts of the brain, and any disease, injury or psychological problem can interfere with the brains function. Amnesia can result from damage to the brain structures that form the limbic system, which controls your emotions and memories. These structures include the thalamus and
Stroke is a medical condition most people are familiar with, but most people are unaware of its effect on memory functions. There have been several studies conducted that study of effects of stroke on different memory systems, how to properly assess memory damage in stroke patients as well as how to improve memory after stroke. A major theme from the course that relates to stroke and memory is the theme of metamemory and its components such as prospective memory. Personally, I believe that these studies offer hope to stroke victims and their families because memory damage can evaluated and therefore a method of treatment can be developed.
Henry Molaison or known as HM contributes to the deep understanding of memory by previous scientists and until now. His case had been a huge research and discussions among the well known scientists during his time and these results in the study of memories. Henry Molaison is living with a severe epilepsy where he need to undergo a surgery as medications were no longer gave him effects for his disease. So, his surgeon William Beecher Scoville suction out both of his hippocampus and when he got recovered from the surgery, his doctor realised that, Henry was having amnesia and seek him for another doctor. What confusing the doctors is that, even though the surgery was a success where Henry seizures decreasing; he is now facing dense memory loss. Then, once it was realized that the hippocampus plays a crucial roles for memory; the surgery of removing hippocampus was then banned for all and this brings to deep study of memory and hippocampus.
Memory is the tool we use to learn and think. We all use memory in our everyday lives. Memory is the mental faculty of retaining and recalling past experiences. We all reassure ourselves that our memories are accurate and precise. Many people believe that they would be able to remember anything from the event and the different features of the situation. Yet, people don’t realize the fact that the more you think about a situation the more likely the story will change. Our memories are not a camcorder or a camera. Our memory tends to be very selective and reconstructive.
