17 Possible Causes for Continuous Rhythmic Slowing, Continuous Slowing - Theta Waves, Generalized Slow Delta Activities

  • Hypoglycemia

    An 84-year-old Japanese woman with metastatic insulinoma suffered from frequent hypoglycemic events. Continuous glucose monitoring (CGM) confirmed severe and frequent symptomatic/asymptomatic hypoglycemia. After the initiation of everolimus treatment, the hypoglycemic events were rapidly eliminated. CGM revealed[…][ncbi.nlm.nih.gov]

  • 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

    Hyponatremia is defined as a serum sodium level of less than 135 mEq/L in a patient. Although hyponatremia is not an uncommon laboratory finding, especially in the elderly, hunting for the etiology is a challenging issue for any clinician. The three first-line investigations that are required for further analysis are[…][ncbi.nlm.nih.gov]

  • Alzheimer Disease

    Alzheimer's disease (AD) related genes have been elucidated by advanced genetic techniques. Familial autosomal dominant AD genes founded by linkage analyses are APP, PSEN1, PSEN2, ABCA7, and SORL1. Genome-wide association studies have found risk genes such as ABCA7, BIN1, CASS4, CD33, CD2AP, CELF1, CLU, CR1, DSG2,[…][ncbi.nlm.nih.gov]

  • Traumatic Brain Injury

    The frequency of alexithymia and the proportion of cases reporting low emotional empathy after traumatic brain injury (TBI) were compared with a control group. The study also examined the relationship between alexithymia and emotional empathy, controlling for the influence of cognitive ability, severity of head[…][oadoi.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] […] and delta), presence of particular EEG patterns (focal or generalized), intermittent activity suppression, or an electrocortical silence.
