A study of recovery of memory function in a case of witnessed functional retrograde amnesia.
Cognitive neuropsychiatry, 1996Co-Authors: Narinder KapurAbstract:We describe a case of transient functional retrograde amnesia that had features of a Fugue State, and that was accompanied by loss of personal identity and significant autobiographical amnesia. Uniquely, we were able to gather information from witnesses who observed the episode from its onset, and we were also able to monitor the acute stages of recovery of memory function over the subsequent four-week period. The profile of memory loss was characterised by impaired performance on both autobiographical and public events memory tasks, in the context of normal anterograde memory test scores. Shrinkage of retrograde amnesia took place over a four-week period, with autobiographical and public events components of retrograde memory recovering at the same rate. We discuss the possible role of unconscious processes underlying the episode, as compared to conscious simulation. We argue that most cases of functional retrograde amnesia may represent a combination of conscious simulation and unconscious processes.

Amnesia in relation to Fugue States--distinguishing a neurological from a psychogenic basis.
The British journal of psychiatry : the journal of mental science, 1991Co-Authors: Narinder KapurAbstract:A case of transient amnesia is described in which a patient reported memory loss for five days, during which he had wandered extensively. Analysis showed that he did not have selective amnesia for the public events which had occurred during the five days for which he professed memory loss. This finding was incompatible with our case having a neurologically based global memory disorder during the Fugue State. These findings offer support for a distinction between personal and public episodic memory.

Éclats d’une voix, éclats d’un « je » : Cadenza for the Schneidermann Violin Concerto de Joshua Cohen
'Springer Science and Business Media LLC', 2013Co-Authors: Stawiarski MarcinAbstract:International audienceBy envisaging the idea of vocality as manifestations of voice in literary texts, this paper examines how voice is represented and analyses the role it plays in Joshua Cohen’s novel (Cadenza for the Schneidermann Violin Concerto, Fugue State Press, New York, 2007). The article argues that J. Cohen’s novel resorts to the image of a disembodied voice as a means of conveying a failed quest of identity and a dismembered and disintegrated subjectivity. Moreover, the article intends to assess the implications of vocality for intermedial and musico-literary studies. The novel’s foregrounding of contentions between voice, text and music becomes an image of both textual adultery and playful treachery, which are essential aspects in musicalized fiction.En proposant de concevoir la notion de vocalité comme manifestation de la voix dans le texte littéraire, cet article examine la représentation de la voix ainsi que sa fonction dans le roman de l’écrivain américain, Joshua Cohen, Cadenza for the Schneidermann Violin Concerto (2007). Nous démontrons que ce roman recourt à l’image d’une voix désincarnée comme moyen de véhiculer une quête d’identité en échec et une subjectivité démembrée, désintégrée, aliénée. Parallèlement, l’article vise à évaluer les implications de la notion de vocalité dans les études intermédiales et musico-littéraires. La rivalité entre voix, texte et musique devient une image de l’adultère du texte et de la tromperie ludique, qui constituent un aspect majeur de la fiction musicalisée

postanesthesia persistent amnesia in a patient with a prior history of dissociative Fugue State the case for the two hit hypothesis
American Journal of Psychiatry, 2013Co-Authors: Inna Roberts, Natalie Gluck, Michael S Smith, Mary F MorrisonAbstract:The psychiatry service was called to evaluate a patient in the outpatient procedure unit who could not remember who she was or why she was there. “Ms. R” was a 36-yearold Hispanic woman with a history of morbid obesity who underwent an upper endoscopy for evaluation of nausea and inability to tolerate oral intake 1 month after a Roux-en-Y gastric bypass for her obesity. The endoscopy demonstrated moderate stenosis at the gastrojejunal anastomosis, which did not account for the severity of her nausea. The stenosis was dilated without incident. For the procedure, Ms. R received a total of 420 mg i.v. of propofol, 100 mg i.v. of lidocaine, and 0.2 mg i.v. of glycopyrrolate. She also received a total of 200 μg i.v. of phenylephrine for a transient decrease in blood pressure to 81/45. In the recovery room, when Ms. R awoke from her conscious sedation, she had no recollection of why she was in the hospital, was disoriented to place, and, most significantly, was unable to recall her identity. She was agitated, prompting the psychiatric consultation. Ms. R was visibly frightened when any person tried to approach her, including her boyfriend of 5 years. She repeatedly asked why she was there but was unable to retain the information received. She was given 2 mg of midazolam for agitation, after which a minor improvement in behavior was observed. A repeat dose of midazolam was administered, without further improvement. Forty-five minutes after the procedure, Ms. R was still unable to recall her date of birth. Her vital signs and general physical and neurological examination were within normal limits. Her mental status examination was significant for agitation, disorientation to person and place, and extensive memory loss, which continued for the rest of the day. She repeatedly expressed the delusion that the baby she had just delivered was taken from her. She had no evidence of hallucinations. A preprocedure pregnancy test was negative. Ms. R was on a liquid diet and taking a multivitamin once daily, 1,000 μg of vitamin B12 three times a week sublingually, and calcium citrate daily. Ms. R’s past medical history included a history of gallstones as well as the Roux-en-Y gastric bypass surgery 1 month earlier, at which time her body mass index (BMI) was 47. Ms. R had received 200 mg of propofol as part of the anesthesia during the 3-hour bariatric surgery without incident. Ursodiol was begun 3 weeks before the endoscopy for nausea that developed while she was consuming a postoperative liquid diet. When her diet was advanced to soft foods, she began vomiting. She returned to a liquid diet, and the endoscopy was scheduled. Ms. R’s past psychiatric history was significant for a dissociative Fugue, which occurred at the same time as her divorce 7 years earlier and for which she was psychiatrically hospitalized. She continued in individual and group treatment for 2 years after that hospitalization. She had no history of traumatic events. Because of Ms. R’s persistent amnesia and agitation, she was admitted to amedical unit for further evaluation. Results of all testing, routine laboratory tests, urine drug screen, head CT, head MRI, and EEG were normal except for ketones in the urine. Ms. R’s BMI had decreased to 40.5. She was started on a clear liquid diet and had no further nausea. The neurology consultant agreed with the psychiatrist’s diagnosis of dissociative amnesia. During her hospitalization, Ms. R slowly regained some of her memory. She vaguely remembered that she had an adult son living in another State. Ms. R could not remember how to use her cell phone. She was afraid to take a shower without supervision as she was not sure she would know what to do. She also could not recall important historical events, such as the September 2001 attacks on the World Trade Center. There was no evidence of anterograde amnesia after the first hospital day. After showing some improvement over her 6-day hospitalization, she was discharged home with her boyfriend. Two weeks after hospital discharge, Ms. R continued to recover some of her memories and to increase her activities. It was unclear, however, whether her retrograde amnesia was improving or whether she was only retaining newly learned information. She began to cook on her own and reported increased comfort around her boyfriend and her family. Ms. R was afraid to return to work because she was concerned that she would not remember how to do her job. Within 2 months of the episode, Ms. R was retrained by her employer and successfully resumed her work as a secretary. Six months after the procedure, Ms. R’s retrograde amnesia had significantly improved and she continued to form new memories without difficulty.

a case of persistent retrograde amnesia following a dissociative Fugue neuropsychological and neurofunctional underpinnings of loss of autobiographical memory and self awareness
Neuropsychologia, 2008Co-Authors: Kristina Hennigfast, Franziska Meister, Thomas Frodl, Anna Beraldi, Frank Padberg, Rolf R Engel, Maximilian F Reiser, Hansjurgen Moller, Thomas MeindlAbstract:Autobiographical memory relies on complex interactions between episodic memory contents, associated emotions and a sense of self-continuity over the course of one's life. This paper reports a study based upon the case of the patient NN who suffered from a complete loss of autobiographical memory and awareness of identity subsequent to a dissociative Fugue. Neuropsychological, behavioral, and functional neuroimaging tests converged on the conclusion that NN suffered from a selective retrograde amnesia following an episode of dissociative Fugue, during which he had lost explicit knowledge and vivid memory of his personal past. NN's loss of self-related memories was mirrored in neurobiological changes after the Fugue whereas his semantic memory remained intact. Although NN still claimed to suffer from a stable loss of autobiographical, self-relevant memories 1 year after the Fugue State, a proportionate improvement in underlying fronto-temporal neuronal networks was evident at this point in time. In spite of this improvement in neuronal activation, his anterograde visual memory had been decreased. It is posited that our data provide evidence for the important role of visual processing in autobiographical memory as well as for the efficiency of protective control mechanisms that constitute functional retrograde amnesia.
