794 Possible Causes for Amnesia, Memory Impairment

  • Vitamin B12 Deficiency

    These results suggest that memory retention impairment formed during vitamin B 12 deficiency is partially attributable to oxidative stress. Copyright 2016 The Authors.[ncbi.nlm.nih.gov] This can consequentially lead to very severe symptoms of deficiency, ranging from depression over the destruction of nerves in limbs and the spinal cord to severe amnesia.[b12-vitamin.com] Symptoms include slow mentation, memory impairment, attention deficits and dementia. Optic neuropathy occurs occasionally in adult patient.[ncbi.nlm.nih.gov]

  • Brain Concussion

    Deficits in working memory can impair a person's ability do everyday things, such as multitasking, Ellemberg said.[livescience.com] A period of amnesia, or not recalling what has happened, is essential to the diagnosis of concussion.[brainfoundation.org.au] Some patients may experience transient loss of inability to create new memories or other brief impairment of mental functioning. Treatment is symptomatic.[ncbi.nlm.nih.gov]

  • Alzheimer Disease

    The MCI patients showed impairment of everyday memory tasks requiring delayed recall.[dx.doi.org] Amnesia: A minimal model and an interpretation. In Cermak, L. S. (ed.), Human Memory and Amnesia, Lawrence Erlbaum Associates, Hillsdale, NJ, pp. 305–336.[oadoi.org] CONCLUSIONS: Memory impairment is a more accurate predictor of early AD than atrophy of MTL on MRI , whereas CSF abnormalities and memory impairment are about equally predictive[ncbi.nlm.nih.gov]

  • Traumatic Brain Injury

    RATIONALE: We report on a patient who showed delayed degeneration of the left fornical crus with verbal memory impairment following mild traumatic brain injury (TBI), which[ncbi.nlm.nih.gov] This period will approximate the duration of posttraumatic amnesia.[web.archive.org] The patient showed mild memory impairment (especially short-term memory impairment) at 3 months after onset: Memory Assessment Scale (global memory: 95 (37%ile), short-term[ncbi.nlm.nih.gov]

  • Stroke

    Memory impairments are common after stroke, and the anatomical basis for impairments may be quite variable.[ncbi.nlm.nih.gov] Papanicolaou, AC, Levin, HS, Eisenberg, HM, Moore, BD, Goethe, KE, High, WM Evoked potential correlates of posttraumatic amnesia after closed head injury.[journals.sagepub.com] […] new information memory problems Effects of a stroke in the cerebellum: The cerebellum is located beneath and behind the cerebrum towards the back of the skull.[web.archive.org]

  • Dementia

    The mechanisms underlying age-associated memory impairment are, however, not understood.[ncbi.nlm.nih.gov] As arteriosclerotic brain disease progresses, amnesia tends to extend further into the past,… Read More[britannica.com] Graveline, for one, is certain that Lipitor was to blame for his 1999 amnesia incident.[scientificamerican.com]

  • Migraine

    (retrosplenial cortex 41 ), muscle weakness and impaired motor coordination (motor cortex 42 ), attention deficits (parietal association cortex 43 ), and visual disturbances[ncbi.nlm.nih.gov] Some children also experience recurrent episodes of transient amnesia and confusion. Episodes typically last less than 6 hours and are followed by deep sleep.[emedicine.com] Retrosplenial amnesia . Brain 110 , 1631–1646 (1987). 42. Donchin, O. , Gribova, A. , Steinberg, O. , Bergman, H. & Vaadia, E.[doi.org]

  • Transient Global Amnesia

    Baclofen-induced amnesia in rodents is a reliable model of memory impairment. In contrast, baclofen-induced memory impairment in humans is uncommon.[ncbi.nlm.nih.gov] […] as transient global amnesia.[ncbi.nlm.nih.gov] Transient global amnesia comprises sudden changes in people's emotional state, which has a major impact on and interacts with episodic memory impairment.[ncbi.nlm.nih.gov]

  • Vascular Dementia

    impairment and other deficits to meet operationalized criteria for dementia, and (3) the use of limited test batteries whose psychometric properties are incompletely understood[ncbi.nlm.nih.gov] In 2012, he developed gait disturbance and mild amnesia. One year later, his gait disturbance worsened, and he developed urinary incontinence.[ncbi.nlm.nih.gov] CASE REPORT We report a 51-year-old right-handed man with no medical history, who presented an acute onset vascular dementia associated with an antero-retrograde amnesia,[ncbi.nlm.nih.gov]

  • Wernicke-Korsakoff Syndrome

    The pattern of both anterograde and retrograde memory impairment and frontal pathology is shown to be comparable with that observed in patients with Wernicke-Korsakoff Syndrome[ncbi.nlm.nih.gov] Anterograde amnesia could therefore be the expression of damage to an extended hippocampal system, and the distinction between temporal lobe and diencephalic amnesia has limited[ncbi.nlm.nih.gov] impairment.[ncbi.nlm.nih.gov]
