Organic Amnesia Research Paper

To what extent do you believe that psychogenic amnesia is distinct from organic amnesia?

Amnesia is the total or partial loss of memory and can affect different types of memory (Madan, 2011). In order to be able to help those with amnesia using the best treatment, the different forms of amnesia need to be understood correctly. In knowing this, the treatment can be designed around the type of amnesia, with the cause, symptoms and ways to help becoming more specific and focused. By studying the diseases and improving our knowledge of the roles that memory plays we can increase our understanding of the brain structures and how the types of memory fit together. In this essay I am going to look at Psychogenic Amnesia (PA) and Organic Amnesia (OA), …show more content…

Instead stress or other psychological factors trigger the amnesia (McKay & Kopelman, 2009). The characteristics include retrograde amnesia (RA): the inability to remember memories previously made. This tends to affect the few years before the onset of amnesia and spares more distant memories (Reed & Squire 1998). Another symptom is slight anterograde amnesia (AA): the inability to form new memories. AA is a minor impairment within PA (Kritchevsky, Chang & Squire, 2004). The most significant indication of PA is the loss of personal identity and autobiographical memories (Serra et al., 2007). OA is caused by brain damage (Madan, 2011). The main characteristic of OA is severe AA. Patients also suffer from RA, with the severity of this varying between patients (Serra et al., 2007). The main difference between these two types of amnesia is the cause: one is psychological; the other is biological. In brain imaging scans PA patients display no sign of brain damage while OA patients’ scans always exhibit brain damage (Reed & Squire, 1998). In PA, it is psychological stresses that trigger memory loss, for example, events such as bereavement, financial issues or having a history of psychiatric illness or receiving a mild head injury (Kritchevsky et al., …show more content…

(2007) all underwent neuroradiological and neurophysiological exams to determine the presence of brain damage and confirm the form of amnesia they had. The results were consistent in that the case study with PA showed no brain damage while the OA case studies did show brain damage in the frontal lobes and hippocampus. Yet, only one PA case study is looked at while there are two OA cases in the Serra et al. (2007) paper, this isn’t a large sample. A problem encountered with finding case studies to compare is that individuals suffering from the amnesia being investigated can be rare and so finding larger samples is very difficult. This can lead to generalizability

Allegory Of The Cave And Skepticism Essay

As a child, we have little that takes up space in the memory bank of our brains, but as time goes on we develop new memories, develop beliefs based on new knowledge. We access those old memories less and less, making the reliability of those earlier memories questionable. On the other hand, suppose a person has developed a mental disorder or age has caught up to them and they suffer from Dementia or Alzheimer's, the reliability of their memories would also be questionable but on the grounds that their minds aren’t functioning

Moreover, “a behavioural syndrome results showing not only semantic-memory impairment but also particular difficulty remembering past events as personal happenings” (Tulving, 1989). Lastly, in Endel Tulving’s conclusion to his article he states “traditionally held views about the unity of memory are no longer tenable. A more appropriate view seems to be that of multiple memory systems. Remembering one’s past is a different, perhaps more advanced, achievement of the brain than simply knowing about it” ( Tulving,

Multistore Model Of Memory Analysis

This is what other researchers have thought of too, and therefore a conclusion was made that additional processes have been taking place as well. Another strength is that there is neuropsychological evidence for this model as a patient, HM (Milner, 1966) underwent surgery which impaired his hippocampus and in turn affected his long-term memory as it no longer functioned properly, whereas his short-term memory was rather functional. Due to this we can conclude that these two processes are involved in the process of memory, as one of the stores was affected when the brain was damaged but the other was not (Baddeley, 2009).

Biological Basis Of Memory Essay

1648 Words | 7 Pages

The biological approach to the basis of memory is explained in terms of underlying biological factors such as the activity of the nervous system, genetic factors, biochemical and neurochemicals. In general terms memory is our ability to encode, store, retain and recall information and past experiences afterwards in the human brain. In biological terms, memory is the recreation of past experiences by simultaneous activation or firing of neurons. Some of the major biopsychological research questions on memory are what are the biological substrates of memory, where are memories stored in the brain, how are memories assessed during recall and what is the mechanism of forgetting. The two main reasons that gave rise to the interest in biological basis of memory are that researchers became aware of the fact that many memory deficits arise from injuries to the brain.

Amnesia Case Study Psychology

1296 Words | 6 Pages

One famous case of amnesia supporting Squire's view is patient H.M. (Scoville & Milner, 1957), who had parts of his left and right temporal lobe, hippocampus, amygdala and surrounding areas of both removed. He developed severe anterograde amnesia, the inability to learn new information, resulting in an almost completely absent short-term memory storage. He also had moderate retrograde amnesia, unable to remember information between 3 to 11 years prior to his surgery, but with other long-term memories unaffected. Explaining this, Squire argued that memories are consolidated in the hippocampus, easily disrupted by trauma during this. They become less dependent on the hippocampus with time, eventually being stored in the neocortex (Alvarez &
