Electroencephalogram (EEG) showed diffuse slowing. Brain MRI revealed a non-enhancing region of restricted diffusion and fluid-attenuated inversion recovery (FLAIR) hyperintensity in the splenium of the corpus callosum (Fig. 1a–c). Magnetic resonance angiography (MRA) of the head and neck was ...
These differences were statistically more robust than the typical changes in the frequency domain (diffuse slowing) and were significantly correlated with the cognitive decline. The adaptive spatial segmentation into microstates is discussed as a method to extract meaningful EEG parameters for the early ...
In MRI scans, three patients showed traumatic lesions (slight epidural haematoma, haemorrhagic contusions and white matter lesions indicating diffuse axonal injury). In the EEG recordings, no generalized slowing or focal changes were found. Structural and functional impairment can be identified using ...
His neurological examination reveals dysmetria, gait ataxia and diffuse hyporeflexia. This man has a 13-year-old daughter (patient 4.2), born at term from an uneventful pregnancy. At 6 months of age, she developed episodes of vertigo and ataxia with vomiting. She learned to walk at 16 ...

Background: In Alzheimer's disease (AD), well-known neurophysiologic changes are the diffuse slowing of oscillatory activity and the loss of functional connectivity between different brain regions. More recently, the application of graph theory to EEG and MEG data has demonstrated a loss of ...
On each participant an EEG was performed within 24 hours after admission. EEG recording performed right after the injury was normal in 67 (58.8%) of cases and abnormal in 47 (41.2%) cases. From all abnormal recordings, EEG in 19 (16.6%) patients demonstrated diffuse dysrhythmia. Slowing ...
