BACKGROUND: Vascular risk factors increase the risk of Alzheimer's disease (AD), but there is limited evidence on whether comorbid vascular conditions and risk factors have an impact on disease progression. The aim of this study was to examine the association between vascular disease and vascular risk factors and progression of AD. METHODS: In a longitudinal observational study in three Norwegian memory clinics, 282 AD patients (mean age 73.3 years, 54% female) were followed for mean 24 (16-37) months...

Objectives Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is characterised by strategic white matter (WM) hyperintensities on MRI. Pathological features include WM degeneration, arteriolosclerosis, lacunar infarcts and the deposition of granular osmiophilic material. Based on the hypothesis that the gliovascular unit is compromised, we assessed the nature of astrocyte damage in the deep WM of CADASIL subjects. Methods We evaluated post-mortem brains from CADASIL, cerebral small vessel disease, similar age cognitively normal and older control subjects...

Small vessel vascular disease is a spectrum of different conditions that includes lacunar infarction, alteration of deep white matter, or microbleeds. Hypertension is the main risk factor, although the atherothrombotic lesion may be present, particularly in large-sized lacunar infarctions along with other vascular risk factors. MRI findings are characteristic and the lesions authentic biomarkers that allow differentiating the value of risk factors and defining their prognostic value.

Patients with type 2 diabetes mellitus have an increased risk of cardiovascular (CV) morbidity and mortality. Recently, brain has been described also as a target organ for diabetic microvascular complications. Cerebral small vessel disease (SVD) may cause lacunar infarcts and cognitive dysfunction. In our case a brain MRI scan showed distinct lesions, which are mainly caused and seen by long lasting diabetes and hypertension.

We aimed to explore the morphological evolution of recent small subcortical infarcts (RSSIs) over 15 months. Moreover, we hypothesized that quantitative lesion apparent diffusion coefficient (ADC) values and serum neurofilament light (NfL) levels predict subsequent lacunar cavitation. We prospectively studied 78 RSSI patients, who underwent pre-defined follow-up investigations three and 15 months poststroke using 3 T MRI including high-resolution T1 sequences. To identify potential predictors of cavitation, we determined RSSI size and quantitative ADC values, and serum NfL using the SIMOA technique...

BACKGROUND: Wernekink commissure syndrome causes a peculiar combination of internuclear ophthalmoplegia, dysarthria, and delayed-onset palatal myoclonus. Palatal myoclonus is thought to be secondary to delayed hypertrophic degeneration of the bilateral inferior olivary nuclei secondary to involvement of bilateral dentatoolivary tract. We describe a case of a patient with early-onset palatal myoclonus. CASE PRESENTATION: A 53-year-old Caucasian man with several vascular risk factors presented to our emergency room with slurred speech, double vision, difficulty with swallowing and walking, and rhythmic contractions of the soft palate...

Patients with large artery intracranial occlusive disease (LAICOD) are at risk for both acute ischemia and chronic hypoperfusion. Collateral circulation plays an important role in prognosis, and imaging plays an essential role in diagnosis, treatment planning, and prognosis of patients with LAICOD. In addition to standard structural imaging, assessment of cerebral hemodynamic function is important to determine the adequacy of collateral supply. Among the currently available methods of assessment of cerebral hemodynamic function, measurement of cerebrovascular reactivity (CVR) using blood oxygen level-dependent (BOLD) MRI and precisely controlled CO2 has shown to be a safe, reliable, reproducible, and clinically useful method for long-term assessment of patients...

BACKGROUND: The mechanism of lacunar stroke (LS) is rather speculative due to the lack of neuropathological evidence in clinical practice. To explore the significance of the occlusion site of the lenticulostriate artery (LSA) to this mechanism, we investigated the characteristics and prognosis of patients with LS with proximal occlusions. MATERIALS AND METHODS: We studied 202 patients with acute LS in the region of the LSA. The presumed occlusion site of the LSA was assessed on coronal, diffusion-weighted magnetic resonance images...

BACKGROUND: Stroke is still a major global health problem in both developed and developing countries. Defining stroke subtype and underlying etiologies is a major step to choose the best method for prophylaxis. Homocysteine is an endothelial toxin and elevated levels have been associated with stroke risk. In this study, we hypothesized that serum total homocysteine level may be related with specific atherothrombotic ischemic stroke subtypes and aimed to find if high serum homocysteine levels are correlated with any specific ischemic stroke subtype...

[Purpose] The relationship between white matter lesions (WMLs) and pushing behavior (PB) is still poorly understood. The purpose of this study was to investigate whether damage from WMLs affects the functional outcome of PB after acute stroke. [Subjects and Methods] In total, 37 patients were included. PB was assessed using the standardized Scale for Contraversive Pushing (SCP). Stroke types were classified as total anterior circulation infarct (TACI), partial anterior circulation infarct (PACI), or lacunar syndrome using the Bamford classification...

A 55-year-old man with no history of stroke or migraine presented to the clinic with cognitive impairment and depression that had been experiencing for two years. Neurological examination showed bilateral pyramidal signs, and impairments in cognition and attention. Brain MRI revealed multiple lacunar lesions and microbleeds in the deep cerebral white matter, subcortical regions, and brainstem, as well as diffuse white matter hyperintensities without anterior temporal pole involvement. Cerebral single-photon emission computed tomography (SPECT) revealed bilateral hypoperfusion in the basal ganglia...

BACKGROUND AND PURPOSE: Insights into evolution of cerebral small vessel disease on neuroimaging might advance knowledge of the natural disease course. Data on evolution of sporadic symptomatic lacunar infarcts are limited. We investigated long-term changes of symptomatic lacunar infarcts and surrounding white matter on structural magnetic resonance imaging. METHODS: From 2 nonoverlapping, single-center, prospective observational stroke studies, we selected patients presenting with lacunar stroke symptoms with a recent small subcortical (lacunar) infarct on baseline structural magnetic resonance imaging and with follow-up magnetic resonance imaging available at 1 to 5 years...
