When people lose their ability to memorize data, they have amnesia. Amnesia also refers to an inability to recall information that is stored in memory. In simple terms, amnesia is the loss of memory. The causes of amnesia may be organic or functional. Organic causes may include brain damage through injury, or the use of specific drugs - usually sedative drugs. Amnesia may be one of the symptoms of some degenerative brain diseases, such as Alzheimer's disease. Functional causes are psychological factors, such as defense mechanisms. People with amnesia also find it hard to imagine the future, because our constructions of future scenarios are closely linked to our recollections of experiences. Being a little forgetful is completely different to having amnesia. Amnesia refers to a large-scale loss of memories that should not have been forgotten. These may include important milestones in life, memorable events, key people in our lives, and vital facts we have been told or taught (Nordqvist, 2009). There is an array of types of amnesia, but the most prominent types like anterograde, retrograde, transient global, dissociative, and traumatic affect many individuals daily.
“I do not even know how long she has been gone. It is as if I have woken up in bed and she is not here... because she is gone to the bathroom or something. Somehow, I know she is never going to come back to bed. If I could just... reach over and touch... her side of the bed, I would know that it was cold, but I cannot. I know I cannot have her back... but I do not want to wake up in the morning, thinking she is still here. I lie here not knowing... how long I have been alone. So how... how can I heal? How am I supposed to heal if I cannot... feel time?” (Nolan, 2000). T...

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...
Traumatic brain injuries (TBI) account to a third (30.5%) of all injury-related deaths in the U.S. with an estimated 1.7 million individuals sustaining TBI each year (Center for Disease Control and Prevention, 2010). Classifications of brain injury (e.g., mild, moderate and severe) is mostly done using the Glasgow coma scale (GCS) which has gained broad acceptance for the assessment of the severity of brain damage (Bauer & Fritz, 2004). Recent studies suggest that almost all patients with moderate or severe TBI have a period of recovery during which they are responsive but confused. This state is commonly referred to as the post-traumatic amnesia. Post-traumatic amnesia (PTA) is defined as “a failure of continuous memory” (Artiola et al., 1980; p.377). PTA is often cited as the best method for codifying the degree, level of recovery and outcome after a closed head injury (e.g., Artieola et al., 1980; Tate, Pfaff, & Jurjevic, 2000). PTA duration is a better indicator of outcome than early injury scales such as the GCS score (Richardson et al., 2009).This analysis will examine the limitations of the general PTA assessment scale, and investigate the benefits and limitations of both retrospective and prospective methods used to measure the duration of PTA.
On a scale from one to ten, I give this movie a seven. This film was well written and directed; the he plot was confusing at first, once I figured out that Christopher Nolan was trying to do, the rest of the story line was fairly easy to follow.
Memory loss-forgetting information really easy,Trouble planning and problem solving, Daily tasks,Times and places are confusing,Changes in Vision,Words and conversations are frustrating.Memory loss means forgetting information really easy. Trouble planning and problem solving turns tricky to follow a recipe, even one you’ve used many times. Is it hard to concentrate on detailed tasks that involves numbers. Daily tasks are a challenge ,familiar things can become hard. You have trouble driving to a location you go to often. Times and places are confusing get disoriented, get lost easily and forget where you are ,and how you got there.Changes in Vision makes it harder to read the words on the page.You have trouble judging distance,and can’t tell colors
“Dementia is the progressive deterioration in cognitive function - the ability to process thought” (Nordqvist, 2009, para. 1) and can be separated into two main categories: cortical and subcortical, physically speaking; for example, Alzheimer’s disease is a type of cordical dimentia, while Parkinson’s disease is classified as subcortical in nature. Many of the people suffering from these afflictions, which are usually middle-aged and older, appear to lose the ability to recall particular events, time of day, or in more advanced stages, the identity of their friends and family. Other symptoms of this condition have been reported as difficulty with speech, depression, balance issues and general disorientation.
Memory plays a significant role in the everyday lives of people of all ages. It allows them to recall information and remember skills that were learned in the past. Memory also organizes past information to help people make current and future decisions. However, imagine forgetting the names of close family members or not having the ability to find your keys every time you want to leave the house. These are some of the struggles that people with Alzheimer’s disease face daily. Alzheimer’s disease was first identified by German neurologist Alois Alzheimer in 1906, and was discovered to have an overpowering effect on explicit memory loss (Gruetzner, 1988). There are two types of Alzheimer’s disease – early onset and late onset. Early onset occurs in patients who are diagnosed before the age of 65 whereas late onset occurs in patients who are diagnosed after the age of 65. In the early stages of Alzheimer’s disease, short-term memory is often lost. As Alzheimer’s disease progresses, problems with long-term memory begin to develop, in addition to short-term memory impairments. Although a lot is known about the symptoms of Alzheimer’s disease, the cause has not been conclusively identified. However, as research continues, new theories about the cause of Alzheimer’s disease are being proposed. This has led to a controversy over whether Alzheimer’s disease is caused by genetics or environmental influences (Gruetzner, 1988).

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...
Amnesia, a severe long-term memory loss disease, is caused by damaged brain tissue. There are two different types of amnesia. Retrograde amnesia is also known as backward moving. This is when you have a hard time remembering the past, especially episodic memories. This occurs because of memory consolidation. Memory consolidation is the process of a new memory setting until it becomes permanently in the brain. If this process is disrupted, the memory may be lost (Hockenberry and Hockenberry page 265). Anterograde amnesia is also known as forward moving. This is when you are unable to form new
I will first be discussing declarative memory, which is characterized by knowledge of facts and events. Much of our current knowledge of the structure and substrates of declarative memory derives from studies of amnesiac patients, from which we can derive two primary findings: declarative memory is separate from other forms of memory such as working and non-declarative memory, and function of declarative memory is dependent on structures
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.
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.

As a human it is normal to forget information, however it is important to realize the difference between a memory slip and amnesia. Amnesia is defined as an inability to recall information that is stored in the memory. In largescale it’s a loss of memory that should never have been forgotten. As research has been conducted science has gained knowledge about the causes, symptoms, types and treatments of amnesia.
