Increase in Ventricle Size and the Evolution of White Matter Changes on Serial Imaging in Critically Ill Patients with COVID-19.

Neurocrit Care 2021 Mar 5. Epub 2021 Mar 5.

Department of Neurology, NYU Langone Medical Center, New York, NY, 10016, USA.

Background: Evolution of brain magnetic resonance imaging (MRI) findings in critically ill patients with coronavirus disease 2019 (COVID-19) is unknown.

Methods: We retrospectively reviewed 4530 critically ill patients with COVID-19 admitted to three tertiary care hospitals in New York City from March 1 to June 30, 2020 to identify patients who had more than one brain MRI. We reviewed the initial and final MRI for each patient to (1) measure the percent change in the bicaudate index and third ventricular diameter and (2) evaluate changes in the presence and severity of white matter changes.

Diffusion-weighted imaging in Huntington's disease.

Mov Disord 2006 Jul;21(7):1043-7

Department of Neurology, Innsbruck Medical University, Innsbruck, Austria.

Huntington's disease (HD) is an autosomal dominant progressive neurodegenerative disorder that results from an expanded trinucleotide (CAG) repeat on the huntingtin gene. Neurodegeneration in HD affects most prominently the basal ganglia. Therefore, diffusivity was obtained in the basal ganglia and thalamus of 29 patients with early HD and 27 healthy volunteers by means of the trace of the diffusion tensor (Trace(D)). Read More

The correlation between neuropsychological and neuroanatomic changes over time in asymptomatic and symptomatic HIV-1-infected individuals.

Neurology 1996 Jun;46(6):1697-702

AIDS Neurologic Center, University of North Carolina School of Medicine, Chapel Hill 27599, USA.

To determine the relationship between neuroanatomic and neuropsychological changes in both asymptomatic and symptomatic HIV-1-infected individuals, we conducted a longitudinal study of 47 HIV-infected individuals, 15 of whom were asymptomatic and 32 of whom had either AIDS-related complex or AIDS. To measure neuroanatomic change over a 30-month period, we conducted quantitative MRI measures of bicaudate/brain ratio (BCR) and bifrontal/ brain ratio. A comparison of change over time between BCR and neuropsychological performance showed a correlation between increase in atrophy and worsening in certain cognitive functions. Read More

CT measurement of suprasellar cistern predicts rate of cognitive decline in Alzheimer's disease.

J Int Neuropsychol Soc 1996 Mar;2(2):89-95

Department of Psychiatry and Behavioral Sciences, Johns Hopkins University School of Medicine, Baltimore, MD 21287, USA.

Previous studies reveal significant relationships between some quantitative computed tomography (CT) measures and level of cognitive functioning in patients with Alzheimer's disease (AD). This study was designed to determine whether measurements from CT scans of AD patients could predict future rates of decline in cognitive function. Subjects were 8 men and 19 women diagnosed with probable AD. Read More

Serial changes of cerebral glucose metabolism and caudate size in persons at risk for Huntington's disease.

Arch Neurol 1992 Nov;49(11):1161-7

Department of Neurology, University of Southern California, School of Medicine, Los Angeles 90033-4606.

Objective: To determine the rate of change of glucose metabolism and caudate size in persons at risk for Huntington's disease.

Design: Eighteen persons at risk for Huntington's disease had two positron emission tomographic glucose metabolic studies and two magnetic resonance imaging scans separated by 42 (+/- 9) months.

Setting: Ambulatory research subjects at a teaching hospital with magnetic resonance imaging and positron emission tomographic technology. Read More

The effects of dialysis on brain water and EEG in stable chronic uremia.

Am J Kidney Dis 1987 Jun;9(6):462-9

Cerebral edema in uremic animals and humans, as well as an EEG deterioration in humans, has been reported after dialysis. Both are manifestations of the dialysis disequilibrium syndrome (DDS). This study was designed to analyze the changes induced by dialysis in the EEG pattern (spectral analysis), in the cerebral hydration, and ventricular size (computed tomography [CT] of the brain) in a group of 11 stable uremic patients.
