47 Possible Causes for Deep White Matter Changes, Dementia, EEG Generalized Slowing

  • 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[] CONCLUSIONS: Abnormal EEG in general and generalized slowing in particular are associated with clinical deterioration after acute ischemic stroke.[] Stroke is a strong, independent, and potentially modifiable risk factor for all-cause dementia.[]

  • Metabolic 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[] The neurological disease complex associated with virus infection occurs in a large proportion of infected patients and is commonly referred to as HIV-1 associated dementia[] Infection of the nervous system by HIV-1 commonly causes a broad range of cognitive, behavioral, and motor abnormalities called, in its most severe form, HIV-1-associated dementia[]

  • 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[] […] as a public health priority; increasing awareness of dementia and establishing dementia-friendly initiatives; reducing the risk of dementia; diagnosis, treatment and care[] Memory loss is a common symptom of dementia. However, memory loss by itself does not mean you have dementia.[]

  • Subacute Sclerosing Panencephalitis

    Later, high signal changes in deep white matter and severe cerebral atrophy were observed.[] The EEG showed irregular background activity with generalized slow waves which were not suppressed with diazepam injection.[] Onset of dementia before 65 years of age is termed as young-onset dementia (YOD).[]

  • Toxic 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[] , and alcoholic dementia.[] What Is Dementia From Toxic Substances?[]

  • Varicella-Zoster Virus Encephalitis

    Imaging shows multiple deep-seated ischemic or demyelinating lesions in neural white matter.[] We studied the rare case of an older adult with dementia following herpes zoster encephalitis (HZE).[] D’Antona R, Baron JC, Samson Y, Serdaru M, Viader F, Agid Y, Cambier J (1985) Subcortical dementia.[]

  • Limbic Encephalitis

    Three patients without temporal–limbic MRI findings had white matter abnormalities in other regions: 1 multifocal, 1 diffuse, and 1 perithalamic and deep white matter changes[] Ten (10/18) patients had temporal lobe epileptic activity with or without general slowing on EEG.[] Most diagnostic imagers are familiar with the classic patterns of altered metabolism seen in Alzheimer disease, frontal temporal dementia, and dementia with Lewy bodies.[]

  • 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[] Independent of adjusting factors, hyponatremia patients had 2.36-fold higher chances of suffering dementia, including Alzheimer's disease (AD) and non-AD dementia, than the[] Stroke is notorious for doubling the risk of suffering dementia (post-stroke dementia), including both AD and non-AD dementia[ 37 ].[]

  • Meningoencephalitis

    Nevertheless, autopsy of the patient revealed frank ischemic changes (subacute infarcts) in the deep hemispheric white matter ( Fig 3 G ).[] Continuous EEG monitoring in the neurologic intensive care unit showed generalized background slowing and frequent spike-and-wave activity.[] We illustrated a 53-year-old man diagnosed with dementia. Neuroimaging and cerebrospinal fluid studies disclosed meningoencephalitis.[]

  • 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[] Prominent posterior slow-wave activity on EEG with periodic fluctuations in the pre-alpha/ theta range.[] Vascular dementia (VaD) is the second most common cause of dementia and its prevalence increases after the sixth decade of life.[]
