15 Possible Causes for Continuous Rhythmic Slowing, Generalized Slow Delta Activities, Slowing - Delta Waves Frontal Bilaterally

  • Hypoglycemia

    A 61-year-old woman with multiple metastatic and unresectable gastrointestinal stromal tumors (GISTs) was referred for investigation of refractory hypoglycemia that developed four months before this hospitalization. On admission, her fasting plasma glucose was 38 mg/dL despite 10% glucose infusion. Investigations[…][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]

  • Alzheimer Disease

    The study aim was to estimate the genetic contribution to individual differences in different forms of memory in a large family-based group of older adults. As part of the Late Onset Alzheimer's Disease Family Study, 899 persons (277 with Alzheimer's disease, 622 unaffected) from 325 families completed a battery of[…][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]

  • Meningoencephalitis

    An EEG showed moderate diffuse background slowing and frequent runs of frontally predominant rhythmic delta waves consistent with seizure activity.[jamanetwork.com] Three days later, the patient became tachypneic with bilateral hand jerking.[jamanetwork.com]

  • Cushing Syndrome

    Cushing’s syndrome can develop for two reasons: Medication containing a cortisol-like synthetic compound called glucocorticoid 1, 2 A benign or malignant tumor in the body that makes the adrenal (pronounced uh-DREEN-l ) gland produce too much cortisol 1, 2 Medication Medication is responsible for most cases of[…][web.archive.org]

  • Hydrocephalus

    Hydrocephalus cases were regularly described by Hippocrates, Galen, and early and medieval Arabian physicians, who believed that this disease was caused by an extracerebral accumulation of water. Operative procedures used in ancient times are neither proven by skull findings today nor clearly reported in the[…][ncbi.nlm.nih.gov]

  • 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.
