17 Possible Causes for Deep White Matter Changes, Slowing - Theta Waves

  • Hyponatremia

    In the brain MRI, millimeter-sized chronic microangiopathic ischemic signal changes were observed in the periventricular deep white matter; no mass image was seen in the pituitary[reumatologiaclinica.org]

  • Stroke

    Early features include: loss of grey-white matter differentiation, and hypoattenuation of deep nuclei: lentiform nucleus changes seen as early as 1 hour after occlusion, visible[radiopaedia.org] Relative band-power of the delta, theta, and alpha EEG frequencies, and resulting DAR and DTR ratio measures of the relative intensity of abnormal slow-wave activity, were[journals.plos.org]

  • Dementia

    It may be particularly related to frontal deep white matter lesions. 16 Cognitive and behavioral changes in SVD are due to disruption of the frontal cortico-subcortical circuit[doi.org]

  • Meningoencephalitis

    Nevertheless, autopsy of the patient revealed frank ischemic changes (subacute infarcts) in the deep hemispheric white matter ( Fig 3 G ).[ajnr.org] […] in the delta or theta frequencies and focal sharp-wave activity. 14 Pathological findings of von Economo disease typically consist of a nonhemorrhagic involvement of the[jamanetwork.com] […] level is invariably normal, but oligoclonal band positivity has been reported. 21 An EEG during the acute phase of the illness often shows diffuse unilateral or bilateral slowing[jamanetwork.com]

  • Metabolic Encephalopathy

  • Vascular Dementia

    Several pathogenic mechanisms appear implicated in the causation the deep white matter changes of Binswanger's disease, and hypoxia-ischemia resulting from watershed injury[web.archive.org] Prominent posterior slow-wave activity on EEG with periodic fluctuations in the pre-alpha/ theta range.[indianjpsychiatry.org] Periventricular and deep white matter changes on T 2 -weighted MRI that are excessive for age 2 … … 3. Focal changes in electroencephalographic studies 3 27 1 31.8 D.[dx.doi.org]

  • Lafora Disease

    matter signal, Deep frontoparietal cerebral changes at 10 years of age Child onset: Weakness Clinical Weakness: Proximal; Symmetric Muscle size: Calf hypertrophy Subgroup[neuromuscular.wustl.edu] The EEG record showed background theta activity as well as slow and sharp waves with a paroxysmal tendency.[jnnp.bmj.com] Scoliosis: Less than untreated patients Bone issues: Osteopenia (55%) CNS MRI 37 Pre-Rx: Ventricular enlargement, May improve with treatment; Myelination delay Post-Rx: White[neuromuscular.wustl.edu]

  • Normal Pressure Hydrocephalus

    White matter changes (WMC) INPH is known to be associated with deep white matter changes (DWMC) and smooth periventricular hyperintensity (PVH) [ 51 ] on MRI ( Figure 2B )[intechopen.com] In 13 cases the EEG was abnormal, the abnormality most frequently observed being a of the rhythmic slow wave type, consisting of bursts of monorhythmic theta or delta waves[link.springer.com] White-matter changes: A distinction is drawn between periventricular and “deepwhite matter changes ( e49, e50 ); only the former are considered a sign of NPH.[ncbi.nlm.nih.gov]

  • Uremic Encephalopathy

    white matter changes may be seen, with the appearance of hyperintensity on T2 sequences in the region of internal capsule, corona radiata, and splenium of corpus callosum[neurologyindia.com] There is a generalised slowing of the EEG, most marked frontally, with an excess of delta and theta waves. In chronic renal failure the changes are less dramatic.[jnnp.bmj.com] […] discharges (PLEDS). [37] In hypokalemia, diffuse slow activity can be seen together with paroxysmal delta/theta activity, as well as focal paroxysms of sharp waves and spike-waves[neurologyindia.com]
