14 Possible Causes for Cognitive Defect, Continuous Rhythmic Slowing, Generalized Slow Delta Activities

  • Hypoglycemia

    Intern Med. 2016;55(8):949-53. doi: 10.2169/internalmedicine.55.5737. Epub 2016 Apr 15. Author information 1 Department of Endocrinology and Metabolism, Dokkyo Medical University, Japan. Abstract We encountered a 62-year-old woman who experienced frequent episodes of hypoglycemia. She was diagnosed with postprandial[…][ncbi.nlm.nih.gov]

  • Alzheimer Disease

    Case Western Reserve researchers discover FDA-approved drug rapidly clears amyloid from the brain and reverses cognitive defects.[neurosciencenews.com] "presenile dementia"/ 11. exp "cognitive defect"/ 12.

  • Traumatic Brain Injury

    These may include motor dysfunction (paralysis, balance or gait abnormalities), cognitive impairment (amnesia, disorientation, confusion), speech defects (aphasia, dysphasia[symptoma.com]

  • Stroke

    Thalamic lesions generally produced focal or unilateral delta activity, but the slow activity varied in time of onset, amplitude and degree of focality 16.[scielo.br] In general, fast-growing tumors, such as glioblastoma multiforme or metastatic brain tumors, are associated with focal slow activity occurring in the delta frequency 16.[scielo.br] They found that cortical gray matter lesions alone did not produce slow activity, probably because the pure cortical lesions presumably destroy the neuronal generators located[scielo.br]

  • Hyponatremia

    Introduction The posterior pituitary hormone vasopressin has a primordial role in the pathogenesis of hyponatremia, the commonest electrolyte disorder in inpatients ( 1 – 3 ). Furthermore, studies consistently find an excess morbidity and mortality in patients with hyponatremia compared to patients with normal[…][journal.frontiersin.org]

  • Dementia

    In advanced AD pathology, synaptic dysfunction is another structural defect associated with a decline in memory ( 35 Terry RD.[doi.org] Physical basis of cognitive alterations in Alzheimer's disease: synapse loss is the major correlate of cognitive impairment. Ann Neurol. 1991 ; 30: 572 – 80.[doi.org]

  • Metabolic Encephalopathy

    In the cases of encephalopathy, EEG can register generalized slowing or suppression of the EEG reactivity, loss of fast rhythm with occurrence of diffuse slow activity (theta[neurologyindia.com] […] memory deficit with preservation of remote memory and out of proportion to other cognitive defects.[dartmouth.edu] […] and delta), presence of particular EEG patterns (focal or generalized), intermittent activity suppression, or an electrocortical silence.

  • Wernicke Encephalopathy

    Retentive memory is impaired out of proportion to other cognitive functions in the otherwise alert and responsive patient.[clinicaladvisor.com] Patients exhibit anterograde (defect in learning) and retrograde (loss of memories) amnesias, and confabulation (making up stories).[clinicaladvisor.com]

  • Toxic Encephalopathy

  • Acute Intermittent Porphyria

    Acute intermittent porphyria ( AIP ) is a rare autosomal dominant metabolic disorder affecting the production of heme resulting from a deficiency of the porphobilinogen deaminase. It is the most common of the acute porphyrias. [1] [2] [3] Signs and symptoms [ edit ] The clinical presentation of AIP is highly[…][en.wikipedia.org]
