Psychogenic amnesia.
Time- and content-based memory systems are briefly described so that their importance for a refined analysis of memory disturbances becomes evident. These memory systems are then related to their brain instantiation, emphasizing that there are limbic circuits for encoding different forms of memories, largely cortical networks for memory storage, and a combined temporofrontal network acting to t...
متن کاملPsychogenic and Organic Amnesia. A Multidimensional Assessment of Clinical, Neuroradiological, Neuropsychological and Psychopathological Features
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 psy...
متن کاملPsychogenic amnesia and self-identity: a multimodal functional investigation.
BACKGROUND Patients with psychogenic amnesia generally suffer from episodic memory deficits associated with an impairment of self-identity. While the first is generally attributed to limbic dysfunction, the latter might be related to posterior parietal cortex. METHODS AND RESULTS In a patient with acute repetitive psychogenic amnesia, three different functional investigations (fMRI, electrica...
متن کاملFunctional MR Imaging of Psychogenic Amnesia: A Case Report
We present here a case in which functional MR imaging (fMRI) was done for a patient who developed retrograde psychogenic amnesia for a four year period of her life history after a severe stressful event. We performed the fMRI study for a face recognition task using stimulation with three kinds of face photographs: recognizable familiar faces, unrecognizable friends' faces due to the psychogenic...
متن کاملPsychogenic amnesia: when memory complaints are medically unexplained
Amnesia (Fig. 1) has been defined as ‘an abnormal mental state in which memory and learning are affected out of all proportion to other cognitive functions in an otherwise alert and responsive patient’ (Victor 1971). Memory impairment can affect the learning of new material (anterograde amnesia), owing to impairments in the encoding, storage or retrieval stages. It can also affect the recall of...
