Transient Global Amnesia

Memory can also be affected by lack of sleep. Also peoples inability to remember things can be affected.

In a laboratory study of sleep deprivation, researchers employed a variety of techniques to keep volunteers awake for variable amounts of time. One group of participants was kept awake for 24 hours, and the other was kept awake for 48 hours. During periods of forced wakefulness, participants were required to engage verbal learning tasks such as memorizing the definitions of obscure English words. At the conclusion of the period of forced wakefulness, participants were allowed to sleep for as

The majority of us have an idea of what amnesia is. Although, it's probably a Hollywood stereotype we've seen in movies. Amnesias is a general term for a condition in which an individual loses their capacity to remember or review data that is stored in their memory or create new memories.

Recollecting some of life’s experiences can be done very accurately at times where we can depict details even after a long period of time. For patient H.M. this is the exact case. Patient H.M. suffered from severe anterograde amnesia. Anterograde amnesia patients quite often show normal memory for events that have occurred prior to the incident. Therefore, making it extremely difficult to recall or store information after the incident has occurred. H.M. had been knocked down by a bicycle at the age of 7, began to have minor seizures at the age of 10, and had major seizures after the age of 16. Patient H.M. had brain surgery in the early 1950’s around the time he had been 27 years old. The surgery had been done to alleviate severe symptoms

Additionally, to further support these theories, researchers tend to conduct studies on the famous patient case, HM, to propose the consolidation deficit theory, in which those with amnesia cannot turn short-term memories into long-term memories (Dewar et al., 2010). However, researchers Dewar, Della Sala, Beschin, and Cowan (2010), mentioned that HM’s case does not fully explain why a patient with anterograde amnesia has the ability to get better at cognitive tasks despite being unable to recall having performed those tasks at a previous time. On the same hand, Duff, Wszalek, Tranel, and Cohen (2008) mentioned that most individuals with anterograde amnesia experience heightened intelligence, attention, skill, and reasoning levels (procedural memory).

About three months ago, during the summer, I was living a very unhealthy lifetsyle. For about a week I felt like I wasn't remembering things that should have been easily known. During normal daily activites such as work, I would tend to forget things that would have been easy to remember any other day. I've been working as a deilvry driver at a pizzeria now for close to 2 years, and I know the neighborhood extremly well. However, during this time, I was starting to forget items at the pizzeria such as sodas or where streets were, that I knew extremly well. It is for these reasons that I feel like I was experiecing symptoms of disaciative amnesia

Dissociative amnesia or any dissociative disorder is never came up in my life as a topic or any condition that I knew of, other than hearing about it in my previous psychology classes in high school, I have never had a personal connection to this mental illness and first-hand. The topic never interest me until I read it on the poster topics listed for this class, but I remember reading this disorder and I wondered how it was different from the simple amnesia that everyone is commonly aware of. After reading about it in the DSM-5 the night following I got my assignment topic I realized I did not have any other association or people close to me that had this mental disorder, I felt confident in contThe night after receiving my poster topic I

The amount of sleep was self-reported by participants using a sleep diary. In the sleep diary participants would note the time they got into bed, how long it took them to fall asleep, the number and duration of awakenings during the night, what time they awoke, and what time they got out of bed. Misinformation or false memory was evaluated in a few different phases. In the first phase the participants took part in a

Amnesia can occur depending on the type and on the cause of amnesia. When the brain is injured, it can interfere with memories because it damages the brain structure that forms the limbic which is what controls the emotions and memories.This can affect many lives because the person could forget a distant relative to a family member as well as it might cause mood swings from being depressed into angry. There is amnesia called neurological amnesia. Neurological amnesia is when the brain gets damaged somehow and what will happen is memory's might get erased or lost. Neurological amnesia can be caused through stroke, seizures, lack of oxygen through the brain like heart attack and long term alcohol drinking. Another type of amnesia is dissociative

The first point to be discussed is posthypnotic amnesia. The article “Hypnosis, Memory and Amnesia” by John Kihlstrom states that “posthypnotic amnesia is a functional amnesia, an abnormal amount of forgetting which is attributable to psychological factors rather than to brain insult, injury or disease.” Posthypnotic amnesia does not occur unless it has been specifically suggested to the subject. It can be seen as more of a temporary state of amnesia, for the amnesia can be reversed and the subject is able to remember events with out any trouble. In the movie Get Out, there is a scene where the main character, Chris Washington, gets out of bed in the middle of the night to get some fresh air. When he is on his way back up to the bedroom he

Sleep is essential for optimal human function. In fact, a lack of sleep can actually affect important cognitive functions, like memory. A 2007 study added to the already substantial evidence that even acute total sleep deprivation impairs attentiveness, working memory, and reaction time in various tasks (Alhola, Polo-Kantola). One such way to further this investigation of the effects of sleep deprivation on memory is through the Memory Interference Test, or MIT. MIT is a program designed by Gaston Pfluegl, Ph.D., and Enrique Lopez, Psy. D., at UCLA to test the memory of students. Along with a memory test, the MIT also anonymously collected the physical states, mental states, and demographics of each student test subject, providing a substantial database through which students can test hypotheses, such as the connection between sleep deprivation and memory. Since the MIT requires short-term memory recall, the hours of sleep a student had before taking the test could have a noticeable effect on his or her performance. An unprecedented study this year found that sleep deprivation may actually even induce false memories, which would certainly impact a student taking the MIT because the test requires the subject to recognize images that have been previously presented to them (Frenda, et al). The hypothesis is that students who slept 8 hours before the test will perform better on the MIT than students who only slept 4 hours. The null hypothesis is that students who had adequate

Amnesia is common recognized psychological problem in daily life and according to Talmi, Caplan, Richards, and Moscovitch (2015), amnesia is usually thought as abilities’ loss in long-term memory regardless of intact of short-term memory. In other words, some people suffer from the amnesia related with the impairment of short-term memory and the others suffer from the amnesia related with the impairment of long-term memory. Those amnesias can happen not only by physical wound, but also psychological trauma. For example, “A 34-year-old man without past history of any psychiatric or neurological disorder developed severe anterograde amnesia following a psychological trauma” (KUMAR, RAO, SUNNY, &GANGADHAR, 2007). When it comes to sorts of amnesias,

Hippocampus is known to play an essential role in encoding and consolidation of acquired memory. While encoding is mostly attributed to animal's waking experience, sleep is believed to support memory consolidation. In support of this theory, the two-stage model predicts 'replay' of wake-induced neural activity in sleep for long term storage. However, one that is debated is how long the hippocampus needs to reverberate the encoded information for long term storage. Some studies have provided a time constant of around ~1hr for the reactivation. However, based on other studies, this timescale of reactivation is put under question. We report here evidences for reactivation in hippocampus continuing for time scales much longer than 1 hr. In addition,

Retrograde Amnesia is, being a common type of Amnesia, is the one most people are familiar with. Retrograde Amnesia is the loss of past memories. If someone falls and hits their head, the damage caused by that accident could cause the person to forget that the accident even occurred. For example, a friend once decided to try snowboarding, and did not learn how to stop before she went to the top of the hill. She went down, picking up speed, and did not notice the small cliff at the bottom until it was too late to turn away. She decided to fall so she would not go over the cliff, and while she was successful at that, she unfortunately hit her head on a patch of ice as she fell. She remained conscience, but lost not only the memory of the accident, she lost her memory of the entire week of the trip.

Memories are precious. They are stored and accessible for the decisions that people make on a daily basis. However, some people do not have this luxury. Clive Wearing is a man who lacks the ability to store memory. Without this ability, Clive has been forced to live a very different life.
