Amnesia
Amnesia is typically defined as partial or total loss of memory. The occurrence of amnesia can arise at any age. Individuals who suffer from amnesia typically remain lucid and preserve their sense of self. Amnesiacs can obtain a perfectly normal appearance despite the amnesia. Moreover, they also have the capacity to read and comprehend words. Based on these facts, researchers have arrived at the conclusion that more than one area in the brain is used for storing facts.
One type of amnesia is Anterograde Amnesia. Anterograde amnesia is defined as severe amnesia and causes superfluous difficulties for those suffering from it. Anterograde amnesia is when people find it extremely difficult to recall ongoing events after a

Another theory held by Anna Freud as to why we do not remember our childhood memories is because children and adults organize memories in different ways based on their brain's development. While still others believe that children begin remembering facts and events once they have accumulated enough to be able to relate experiences to each other.
Another type of amnesia that is unusual but not uncommon is transient global amnesia or TGA for short. TGA is the sudden onset of forgetfulness and confusion. It usually occurs following physical exertion. During a severe attack the victim experiences total disorientation except for their own identity. This is combined with a mild form of retrograde amnesia which subsides when the attack is complete. Attacks usually last anywhere from thirty to sixty minutes and rarely last to be longer than twelve hours. There is no other alteration in consciousness or obvious neurological problems. The person's behavior is otherwise normal and they usually recover completely with in twenty four hours. People suffering from TGA generally have a complete and rapid recovery. The only time in which a patient is treated for TGA is if it is related to atherosclerosis, which is poor cerebral circulation.
A case was reported in London in 1997 by a man in his sixties who had regularly suffered from migraines. He only experienced amnesia when he was having sex. He would ask
* Forgetfulness, maybe forgetting names of people that you have been in contact with every day, or forgetting what you did just hours or days ago.
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.
Because of his anterograde amnesia, Mr. Thompson suffered from declarative memory loss; however, his nondeclarative and procedural memories appeared to be preserved. I believe that Mr. Thompson suffered from an impairment of episodic memory and retained his semantic memories because he could reflect common knowledge of the
Anterograde Amnesia is the inability to store new information after the brain damage has occurred. (Luke Mastin 2010). Anterograde Amnesia is very rare, in fact there have a few cases where the amnesia was "pure". The symptoms and hardship of the person depend on the cause for the memory loss. Some symptoms of Anterograde Amnesia are partial memory loss, having a hard time recognizing relatives or family, feeling of confusion, difficulty taking in new information, inability to remember familiar places, and difficulty in learning and remembering new things.(PHC Editorial Team 2013) Characteristics of Anterograde Amnesia are abnormally small hippocampi bilaterally and elevated hippocampal water.(Mayo Clinic 2014) There are many ways to recognize
A fifty-five year old man is suffering from transient global amnesia. Which of the following would be the most difficult for him to remember?
In the movie 50 First Dates one of the main characters suffers from the severe condition of anterograde amnesia. The movie is about Henry Roth who is a wildlife veterinarian in Hawaii, meeting Lucy Whitmore a woman who has a short-term memory loss from an auto accident a year earlier. Henry meets Lucy at a local cafe and takes her out on a date. Henry falls in love with Lucy, but there is one problem when she awakens in the morning, she can't remember him or anything that happened that day. Henry must devise a plan to meet Lucy everyday and try to get her to fall in love with him again and again.
Amnesia is characterized as loss of memory, or the failure to recollect certainties or occasions. We have two sorts of recollections: the short-term (late, new) and long haul (remote, old) recollections. Fleeting memory is modified in a piece of the cerebrum called the worldly flap, while long haul memory is put away all through broad nerve cell systems in the transient and parietal projections. In Alzheimer's malady, fleeting memory stockpiling is harmed first.
Anterograde amnesia is a common and distinguished neurological disorder in the psychological and neurobiological field. Media depictions of this neuropsychological disorder are not as common as other forms of amnesia, but it is still incorrectly portrayed. Anterograde amnesia refers to the inability to retain new information, while still having intact memories that occurred before brain damage (Carlson, 2014). There have been several studies that focus on anterograde amnesia and its diagnostic criteria, course, associated features, assessment, etiology, underling neurobiological mechanisms, treatments, and future research.
Some scientists believe that parts of long term memory are permanent while others will eventually weaken over time. (3) Long term memory can be divided into three sections: procedural memory, declarative memory, and remote memory. Procedural memory includes motor skills such as learning how to ride a bike or how to drive a car. "Such memories are slow to acquire but more resistant to change or loss." (4) Declarative memory is used to remember facts, such as names, dates and places. It is easy to learn but also easy to lose. Finally there is episodic memory, which is the record of events that a person stores throughout his or her experience. Recent studies show that these events, as soon as they occur, are sent to a temporary part of the brain called the hippocampus, and that over time they are moved to the neocortex for permanent storage. (5).
Anterograde amnesia refers to a memory deficit from brain injury that prevents patients to store new informations in their short term memories. The patients show normal memories for events that occurred before the injury but has severely impaired ability to recall information about events that occurred after the incident. Anterograde amnesia is reflected in the movie “50 first dates” through the main character, Lucy Whitmore, whose memory lasts only a day because her memory stopped on the day of car accident. (additional description) The movie, “50 first dates,” contains valid depiction of anterograde amnesia yet it also contains some dramatic points that is far from reality.
Do you think an experience can be so traumatizing that the brain pushes it into an inaccessible corner of the unconscious to later recall it years later? This concept on the mind is expressed as repressed memories. These are types of memories that are blocked unconsciously due to the high levels of stress experienced during the event. This theory on memories are based on the idea that even though the memory is repressed it is still affecting the individual in their conscious aspects of life. Repressed memories are often associated with childhood sexual abuse. This relies on the idea that these memories of sexual abuse can be brought up either in therapy or by the victim themselves years after the abuse. The concept of repressed memories has been a huge controversy in psychology from the beginning of time. Many people believe that repressed memories in regards to childhood sexual abuse are possible while others believe they can’t be as accurate as some people believe.
A fundamental aspect of human memory is that the more time elapsed since an event, the fainter the memory becomes. This has been shown to be true on a relatively linear scale with the exception of our first three to four years of life (Fitzgerald, 1991). It is even common for adults not to have any memory before the age of six or seven. The absence of memory in these first years has sparked much interest as to how and why it happens. Ever since Freud (1916/1963) first popularized the phenomenon there have been many questions and few robust empirical studies. Childhood amnesia is defined as the period of life from which no events are remembered (Usher & Neisser, 1993) beginning at birth and ending at the onset of your
Losing one’s memory can be a mysterious affliction, and the causes can be quite complex. Severe memory loss is introduced in author Oliver Sacks’ collection of stories The Man Who Mistook His Wife for a Hat, and lectures given by professor Jim Davies can help with understanding of some of the concepts introduced in the book. In chapter two, The Lost Mariner, the patient Jimmie is suffering from aspects of both retrograde and anterograde amnesia, which Davies explained as loss of memory of events or facts learned before an event (the event that caused the amnesia), and loss of ability to create new memories after the event, respectively. In more detail, and in relation to our book (here, the target example), retrograde amnesia would consist of any loss of memory that happened prior to an event, such as an injury or onset of disease in Jimmie’s case. Dr. Davies’ explanation of retrograde amnesia helps to understand Jimmie’s case, where in the year 1975 he is unable to recall any events after 1945. As well, the explanation of anterograde amnesia as including symptoms such as inability to form new memories, learn information or tasks, or to recall the recent past is useful when applied to Jimmie’s experience of not being able to recall events that happened even a few minutes prior. Jimmie’s suffering from both retro and anterograde amnesia, as explained by Sacks, results from Korsakov’s syndrome – a destruction of memory caused by alcoholic
This isn’t even a real condition; however, Barrymore’s symptoms match a real form of amnesia called “anterograde amnesia”. This is surprisingly part of the film that contains some accuracy in terms of psychology. With this type of amnesia, it’s typically caused when a person has some kind of brain damage to a portion of the brain that is partially responsible for the storage of memory. The brain is essentially “stuck in time”. The brain is not able to encode new memories and store those memories. Living with anterograde amnesia would need to be hospitalized so they can be closely monitored. In this movie the character has permanent brain damage sustained from a car accident. She lost the ability to create new memories after the event that caused the amnesia (short term memory loss), however her long-term memories from before the event remain
Case 1 tells the story of Henry Molaison (HM), a man with no memory. He lost his memory due to the operation of suctioned out the hippocampus to treat his epileptic seizures. At that time, it was not known yet that the hippocampus was essential for making memories. After operation, his seizures were significantly reduced, but Henry suffered a global amnesia. Owen et al. (2007) describes patients with global amnesia as perceptive and attentive but with a total loss of short-term memory and some trouble accessing memories of the recent past. Henry could not learn new things as he quickly forgot everything that he had learned. He could learn at a subconscious level only.
