Fibroblast Growth Factor 23 Is Associated With Subclinical Cerebrovascular Damage: The Northern Manhattan Study Clinical Sciences
Conclusions— These cross-sectional community-based data from a diverse urban sample show an association between elevated FGF23 and small vessel disease and magnetic resonance imaging–defined brain infarction in men, independent of chronic kidney disease. Data on elevated FGF23 and subclinical cerebrovascular damage progression are needed.

Cerebral Microbleeds and Chronic Kidney Disease in Acute Ischemic Stroke Patients with Atrial Fibrillation
Background: Cerebral microbleeds (CMBs) are associated with the risk of intracerebral hemorrhage in stroke patients with atrial fibrillation (AF). We investigated the association between CMBs and chronic kidney disease (CKD) in patients with acute ischemic stroke and AF. Methods: We retrospectively examined consecutive patients with acute ischemic stroke and AF who underwent brain gradient-echo T2*-weighted magnetic resonance imaging. The number and distribution (lobar, deep or infratentorial, and mixed) of CMBs were assessed.

Chronic Kidney Disease in Patients With Lacunar Stroke: Association With Enlarged Perivascular Spaces and Total Magnetic Resonance Imaging Burden of Cerebral Small Vessel Disease Clinical Sciences
Conclusions— Proteinuria and impaired estimated glomerular filtration rate are associated with increasing EPVS severity and, furthermore, accumulated magnetic resonance imaging burden of cSVD in patients with first-ever acute lacunar stroke.

Reduction in estimated glomerular filtration rate (eGFR) results in an increased risk of spontaneous hemorrhagic transformation in patients with large-artery atherosclerosis stroke.
In conclusion, reduced eGFR was significantly associated with increased risk of spontaneous HT in all ischemic stroke patients, and in large artery atherosclerosis, not in cardio-embolism stroke. Reduced eGFR did not increase the risk of symptomatic HT. PMID: 26503023 [PubMed - as supplied by publisher]

Underlying embolic and pathologic differentiation by cerebral microbleeds in cryptogenic stroke
ConclusionsCMBs were common, and age, male sex, hypertension, chronic kidney disease, and cerebral white matter diseases were related to CMBs in cryptogenic stroke. Aortic complicated lesions were associated with deep and diffuse CMBs, while prior anticoagulant therapy was related to lobar CMBs.

Impact of Albuminuria on Early Neurological Deterioration and Lesion Volume Expansion in Lenticulostriate Small Infarcts Brief Reports
Conclusions— Our findings suggest that albuminuria is associated with END and infarct volume expansion in patients with small subcortical infarcts in the lenticulostriate artery territory.

Urinary Immunoglobulin G Is Associated with Deep and Infratentorial Cerebral Microbleeds in Stroke Patients
Conclusions: Urinary IgG was associated with the prevalence of D/I or mixed location CMBs in TIA or ischemic stroke patients. Our findings provide new insights into the association between urinary IgG and the distribution of CMBs.Cerebrovasc Dis

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...

New aspects of cerebrovascular diseases in dialysis patients.
Authors: Naganuma T, Takemoto Y Abstract Growing evidence suggests that chronic kidney disease is a significant risk factor for stroke, subclinical cerebrovascular abnormalities, and cognitive impairment, independent of known cardiovascular risk factors. Cerebrovascular disease is also a major cause of death in dialysis patients, who have a much higher incidence of stroke compared to the normal population. Strokes in dialysis patients are also characterized by a higher incidence of hypertensive intracerebral hemorrhage compared with those in the general population. Recent studies on dialysis cohorts have shown that...

Influence of cerebral white matter hyperintensities on cognitive impairment in elderly medical patients
ConclusionsAlthough cognitive impairment in elderly medical patients is associated with stroke and brain atrophy, white matter hyperintensities, especially BGH and infratentorial region, are associated with cognitive decline in relation to CKD. Geriatr Gerontol Int 2016; ••: ••–••.

Association of ankle-brachial index with cognitive decline in patients with lacunar infarction
This study aimed to investigate the relationship of ankle-brachial pressure index (ABI) and brachial-ankle pulse wave velocity (baPWV) with cognitive function in patients with lacunar infarction. We included records of consecutive patients with their first-ever acute stroke and a diagnosis of lacunar infarction through magnetic resonance imaging (MRI) from July 1, 2011 to December 31, 2018. We excluded patients diagnosed with dementia, including strategic single-infarct dementia, before or after stroke onset. Moreover, we excluded patients with one or more microbleeds, severe white matter lesions, or severe medial temporal...

Sedentary Time and White Matter Hyperintensity Volume in Older Adults
Conclusions Findings suggest that sedentary time is associated with WMH in persons with an eGFR ≤96 mL·min−1 per 1.73 m2 and that this association is stronger with lower levels of kidney function.

Subclinical cerebral abnormalities in chronic kidney disease.
Conclusions: The present study showed that community-dwelling elderly subjects with late stage 3 CKD were at high risk for prevalent subclinical lacunar infarction. The identification of CKD-specific modifiable risk factors for SBI and WMLs is of increased importance for prevention of subclinical brain ischemic lesions. PMID: 23652446 [PubMed - in process]

Sleep Duration, Kidney Function, and Their Effects on Cerebral Small Vessel Disease in Elderly Hypertensive Patients.
CONCLUSIONS: In the present study, short sleep duration was a positive significant determinant for WMH and PVH in elderly hypertensives. Sleep duration might serve as a strong determinant for white matter lesions especially in those without CKD. PMID: 25559119 [PubMed - as supplied by publisher]
