Retrograde Amnesia


Presentation

  • In the present study we have made a more precise analysis of retrograde amnesia in petit mal. We made a comparative analysis of the results of polygraphic registration and introspection.[jamanetwork.com]
  • Researchers have tended to explain apparent ‘anomalies’ in memory performance or individual presentation, as manifestations of unconscious or psychological distress-mediated behaviour.[insights.ovid.com]
  • […] eight tests are presented in Figure 8.[jneurosci.org]
  • Our view is that the present findings can accommodate these observations.[ncbi.nlm.nih.gov]
  • The present study represents a step in this direction by exploring retrograde memory across a range of general world knowledge domains in LSJ.[frontiersin.org]
Malingering
  • The present review explores studies relevant to extending the malingering paradigm to retrograde amnesia. Recent findings In the period reviewed, very little work has directly addressed the area of malingered retrograde amnesia.[insights.ovid.com]
Painter
  • In contrast, LSJ was correct for only 1 (2%) and 2 (4%) of the paintings, naming Da Vinci as the painter of Mona Lisa twice and The Last Supper once, t (9) 4.81 and 4.70, p s 0.001.[frontiersin.org]
Disability
  • No control participant reported brain injury or damage, neurological disorder, learning disability, psychiatric disorder, drug or alcohol abuse, vision or hearing impairment, or medications that would affect cognitive function.[frontiersin.org]
Physician
  • A physician friend and his wife, a nurse, were with A.B. at the time of his arrest and were able to administer resuscitation (CPR) immediately.[jneurosci.org]
Contusion
  • In two patients, the pathology resulted from acute head injury and associated contusions and hematomas, worse on the right than the left.[ncbi.nlm.nih.gov]
Hearing Impairment
  • No control participant reported brain injury or damage, neurological disorder, learning disability, psychiatric disorder, drug or alcohol abuse, vision or hearing impairment, or medications that would affect cognitive function.[frontiersin.org]
Suggestibility
  • These and other findings suggest that the hippocampal formation and related structures are involved in certain forms of memory (e.g. autobiographical episodic and spatial memory) for as long as they exist and… CONTINUE READING Tables and Topics from this[semanticscholar.org]
  • There was no suggestion of a gradient difference between the H and H subgroups. On recognition, the mean scores of the two subgroups were closer, and on familiarity, there was a suggestion of a temporal gradient in the H group.[ncbi.nlm.nih.gov]
  • These results, along with LSJ's, suggest that memory for general world knowledge may rely on multiple areas in the medial and lateral temporal lobe.[frontiersin.org]
  • These findings count against the suggestion that the hippocampal formation is needed to retrieve autobiographical memories throughout life ( Nadel and Moscovitch, 1997 ).[jneurosci.org]
  • More specifically, it has been suggested that long periods of retrograde amnesia are characteristic of amnesics with diencephalic lesions.[pnas.org]
Fear
  • CREB required for the stability of new and reactivated fear memories. Nat. Neurosci. 2002; 5 :348–355. [ PubMed ] [ Google Scholar ] Kopelman M.D.[ncbi.nlm.nih.gov]
Amnesia
  • In contrast, research with offenders claiming amnesia for their crimes has emphasized that malingered retrograde amnesia can be identified with relevant assessment methods.[insights.ovid.com]
  • The New Yorker 4 The most common psychological form of retrograde amnesia Kopelman encounters is known as the fugue state. The Guardian - Lifestyle 5 Bruce was suffering from a rare condition known as total retrograde amnesia.[ludwig.guru]
  • […] retrograde amnesia is extensive and can encompass much of a subject's lifetime; the degree of loss may depend upon the type of memory assessed.[semanticscholar.org]
  • This type of amnesia can be short-term and does not always include physical damage to the brain.[alleydog.com]
  • In our former research on the alterations of consciousness in petit mal (Jus and Jus, 1960) we were interested in different kinds of anterograde amnesia in petit mal and also devoted some attention to the problem of amnesia.[jamanetwork.com]
Memory Impairment
  • In summary, A.B. and L.J. exhibited anterograde memory impairment but limited RA.[jneurosci.org]
  • Three cases of enduring memory impairment after bilateral damage limited to the hippocampal formation. J.[ncbi.nlm.nih.gov]
  • One recent study raises the possibility of preservation in an area of premorbid expertise (music) despite severe memory impairment for other kinds of knowledge ( Finke et al., 2012 ).[frontiersin.org]
Seizure
  • Seizure activity ceased after the second hospital day, but he remained comatose for the next 8 d.[jneurosci.org]
  • The fifth patient had suffered complex partial seizures over a period of many years, but developed an identified memory impairment 3 yr before testing, following a severe bout of seizures. In all cases, the atrophy was bilateral.[ncbi.nlm.nih.gov]
Confabulation
  • ., 1988 ) and between genuine and confabulated memories ( Johnson et al., 1997 ). Fig. 7.[jneurosci.org]

Alteration of Consciousness
  • In our former research on the alterations of consciousness in petit mal (Jus and Jus, 1960) we were interested in different kinds of anterograde amnesia in petit mal and also devoted some attention to the problem of amnesia.[jamanetwork.com]

Treatment

  • She underwent a right temporal lobectomy in 1961 for the treatment of intractable epilepsy. She died in 1986 at the age of 79. At autopsy a sclerotic lesion of the unoperated left hippocampus was found.[pnas.org]
  • After treatment, he was breathing spontaneously and maintaining good levels of blood oxygen with minimal supplementation. Seizure activity ceased after the second hospital day, but he remained comatose for the next 8 d.[jneurosci.org]

Etiology

  • On the basis of these findings and the etiology of his amnesia, A.B. is presumed to have circumscribed hippocampal formation damage. This cannot be confirmed with MRI, however, because he wears a pacemaker. Table 1.[jneurosci.org]

Pathophysiology

  • Its value consists in the fact that these psychopathological phenomena explored by introspection can be compared with simultaneously present pathophysiological phenomena explored by polygraphic registration.[jamanetwork.com]

Prevention

  • For the autobiographical test, the mean value across the first two time periods (Childhood, Young Adult) was used in all participants to prevent any confounding by anterograde memories.[ncbi.nlm.nih.gov]
