Functional Characterization of Atrophy Patterns Related to Cognitive Impairment
Introduction: Mild cognitive impairment (MCI) is a heterogenous syndrome considered as a risk factor for developing dementia. Previous work examining morphological brain changes in MCI has identified a temporo-parietal atrophy pattern that suggests a common neuroanatomical denominator of cognitive impairment. [...]

Increased Water Content in Periventricular Caps in Patients without Acute Hydrocephalus
BACKGROUND AND PURPOSE: Periventricular caps are a common finding on MR imaging and are believed to reflect focally increased interstitial water content due to dysfunctional transependymal transportation rather than ischemic-gliotic changes. We compared the quantitative water content of periventricular caps and microvascular white matter lesions, hypothesizing that periventricular caps associated with increased interstitial fluid content display higher water content than white matter lesions and are therefore differentiable from microvascular white matter lesions by measurement of the water content.MATERIALS AND METHODS: In a prospective study, we compared the water content of periventricular caps and white matter lesions in 50 patients using a quantitative multiple-echo, gradient-echo MR imaging water-mapping sequence.RESULTS: The water content of periventricular caps was significantly higher than that of white matter lesions (P = .002).

Dynamic susceptibility contrast parametric imaging using accelerated dual-contrast echo planar imaging with keyhole
BackgroundEcho planar imaging (EPI) is one of the methods of choice in dynamic susceptibility contrast MRI (DSC‐MRI) because it provides a sufficient temporal resolution. However, the relatively long readout duration of EPI often imposes limitations on increased spatial coverage or the use of multiple contrasts.PurposeTo develop a DSC‐MRI method using EPIK (EPI with keyhole) to provide dual‐contrast (TE1 and TE2) information with a higher spatial coverage than EPI.

Cerebral water content mapping in cirrhosis patients with and without manifest HE
Hepatic encephalopathy (HE) is a frequent and debilitating complication of cirrhosis and its pathogenesis is not definitively clarified. Recent hypotheses focus on the possible existence of low-grade cerebral edema due to accumulation of osmolytes secondary to hyperammonemia. [...]

Correlation of quantitative conductivity mapping and total tissue sodium concentration at 3T/4T
Magnetic resonance in medicine 82(4), 1518 - 1526 () [10.1002/mrm.27787]
PurposeTo investigate the correlation between electrical conductivity and sodium concentration, both measured in vivo, in the human brain.MethodsConductivity measurements were performed on samples with different sodium (Na+) and agarose concentrations using a dielectric probe, and the correlation between conductivity and Na+ content was evaluated. Subsequently, brain conductivity and total Na+ content maps were measured in 8 healthy subjects using phase‐based MREPT and sodium MRI, respectively. [...]

Clinical and genetic characteristics of late-onset Huntington's disease
BackgroundThe frequency of late-onset Huntington's disease (>59 years) is assumed to be low and the clinical course milder. However, previous literature on late-onset disease is scarce and inconclusive.ObjectiveOur aim is to study clinical characteristics of late-onset compared to common-onset HD patients in a large cohort of HD patients from the Registry database.MethodsParticipants with late- and common-onset (30–50 years)were compared for first clinical symptoms, disease progression, CAG repeat size and family history.

Cerebral changes improved by physical activity during cognitive decline: A systematic review on MRI studies
Current treatment in late-life cognitive impairment and dementia is still limited, and there is no cure for brain tissue degeneration or reversal of cognitive decline. Physical activity represents a promising non-pharmacological interventional approach in many diseases causing cognitive impairment, but its effect on brain integrity is still largely unknown. [...]

Application of Quantitative Motor Assessments in Friedreich Ataxia and Evaluation of Their Relation to Clinical Measures
The Cerebellum 18(5), 896 - 909 () [10.1007/s12311-019-01073-x]
Friedreich’s ataxia (FRDA) is a rare autosomal-recessive slowly progressive neurodegenerative disorder. As common clinical measures for this devastating disease lack sensitivity, we explored whether (a) the quantitative motor assessments of the Q-Motor battery can enhance clinical characterisation of FRDA; (b) clinical measures can predict Q-Motor outcomes and (c) Q-Motor is sensitive to longitudinal change.

Alterations in basal ganglia-cerebello-thalamo-cortical connectivity and whole brain functional network topology in Tourette's syndrome
Tourette Syndrome (TS) is a neuropsychiatric disorder characterized by the presence of motor and vocal tics. Major pathophysiological theories posit a dysfunction of the cortico-striato-thalamo-cortical circuits as being a representative hallmark of the disease. [...]
