Psychogenic amnesia is a complex disorder characterised by a wide variety of symptoms. Consequently, in a number of cases it is difficult distinguish it from organic memory impairment. The present study reports a new case of global psychogenic amnesia compared with two patients with amnesia underlain by organic brain damage. Our aim was to identify features useful for distinguishing between psychogenic and organic forms of memory impairment. The findings show the usefulness of a multidimensional evaluation of clinical, neuroradiological, neuropsychological and psychopathological aspects, to provide convergent findings useful for differentiating the two forms of memory disorder.

  • What Is It Like to Be Confabulating?
    What is it like to be Confabulating? Sahba Besharati, Aikaterini Fotopoulou and Michael D. Kopelman Kings College London, Institute of Psychiatry, London UK Different kinds of confabulations may arise in neurological and psychiatric disorders. This chapter first offers conceptual distinctions between spontaneous and momentary (“provoked”) confabulations, as well as between these types of confabulation and other kinds of false memories. The chapter then reviews current explanatory theories, emphasizing that both neurocognitive and motivational factors account for the content of confabulations. We place particular emphasis on a general model of confabulation that considers cognitive dysfunctions in memory and executive functioning in parallel with social and emotional factors. It is argued that all these dimensions need to be taken into account for a phenomenologically rich description of confabulation. The role of the motivated content of confabulation and the subjective experience of the patient are particularly relevant in effective management and rehabilitation strategies. Finally, we discuss a case example in order to illustrate how seemingly meaningless false memories are actually meaningful if placed in the context of the patient’s own perspective and autobiographical memory. Key words: Confabulation; False memory; Motivation; Self; Rehabilitation. 1 Memory is often subject to errors of omission and commission such that recollection includes instances of forgetting, or distorting past experience. The study of pathological forms of exaggerated memory distortion has provided useful insights into the mechanisms of normal reconstructive remembering (Johnson, 1991; Kopelman, 1999; Schacter, Norman & Kotstall, 1998). An extreme form of pathological memory distortion is confabulation. Different variants of confabulation are found to arise in neurological and psychiatric disorders.

  • How the Brain and Memory Works 10
    Caring For A Loved One With Dementia 10 How the Brain and Memory Works Introduction The way our brain stores memories is a complex process across many areas of the brain. Luckily, memories are not all stored in one place. They are spread out across different brain regions, or lobes, and allow us to keep and recall memories even if one area of the brain is damaged. Although the brain’s process for storing memories is sometimes compared to a filing cabinet, the processes are extremely complex and still not fully understood. 2 Creating memories 3. Store information The human brain is made up of neurons. Neurons are nerve cells that talk to each other through a synapse- a connection This is the process of retaining the information in short term, or between cells that sends information. Neurons receive and more permanently in long term memory. An area of the brain carry information to the parts of the brain to process or store called the Hippocampus plays an important role in storing long information. The brain has approximately 100 billion nerve term memories. cells, give or take 15 billion. 4. Recall To create memories, the brain must accomplish the following processes: Memories that are frequently recalled become stronger than those accessed less frequently. The neurons linked to this 1. Encode information information create a neural pathway- a road to that memory. Think of it as walking along a path. The more frequently you This process allows something of interest to be stored in the walk on the same path, the more defined the trail becomes.

  • The Three Amnesias
    The Three Amnesias Russell M. Bauer, Ph.D. Department of Clinical and Health Psychology College of Public Health and Health Professions Evelyn F. and William L. McKnight Brain Institute University of Florida PO Box 100165 HSC Gainesville, FL 32610-0165 USA Bauer, R.M. (in press). The Three Amnesias. In J. Morgan and J.E. Ricker (Eds.), Textbook of Clinical Neuropsychology. Philadelphia: Taylor & Francis/Psychology Press. The Three Amnesias - 2 During the past five decades, our understanding of memory and its disorders has increased dramatically. In 1950, very little was known about the localization of brain lesions causing amnesia. Despite a few clues in earlier literature, it came as a complete surprise in the early 1950’s that bilateral medial temporal resection caused amnesia. The importance of the thalamus in memory was hardly suspected until the 1970’s and the basal forebrain was an area virtually unknown to clinicians before the 1980’s. An animal model of the amnesic syndrome was not developed until the 1970’s. The famous case of Henry M. (H.M.), published by Scoville and Milner (1957), marked the beginning of what has been called the “golden age of memory”. Since that time, experimental analyses of amnesic patients, coupled with meticulous clinical description, pathological analysis, and, more recently, structural and functional imaging, has led to a clearer understanding of the nature and characteristics of the human amnesic syndrome. The amnesic syndrome does not affect all kinds of memory, and, conversely, memory disordered patients without full-blown amnesia (e.g., patients with frontal lesions) may have impairment in those cognitive processes that normally support remembering.
