Article Abstract
Introduction: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common monogenic cerebral small vessel disease in adults. This study investigates the occurrence, risk factors, and prognosis of acute cerebral microinfarcts (ACMIs) in patients with CADASIL.
Methods: A total of 60 patients with genetically confirmed or pathologically verified CADASIL were enrolled in the study. ACMIs were identified as hyperintense lesions on diffusion-weighted imaging (DWI) with a diameter of less than 5 mm. The evolution of ACMIs was determined by brain MRI scans at 1 year of follow-up. Functional outcomes, cognitive performance, and quality of life after ACMIs were evaluated at months 6, 12, and 24, respectively.
Results: ACMIs were observed in 12 out of 60 patients (20%) with CADASIL and predominantly located in the white matter. Patients with CADASIL had a significantly higher risk of ACMIs when they had a patent foramen ovale (PFO) (OR, 16.429). On follow-up MRI scans at month 12, the majority of ACMIs vanished. Patients with ACMIs had worse functional outcomes, as indicated by higher mRS scores and lower MoCA scores at months 12 and 24 compared with those without ACMIs. Additionally, patients with ACMIs had significantly worse EQ-5D-3L scores at all follow-up points compared with patients without ACMIs.
Conclusions: ACMIs were not rare in patients with CADASIL. PFO could independently predict the risk of ACMIs in CADASIL. Furthermore, the majority of ACMIs can disappear at 1 year of follow-up. The findings indicate that ACMIs, influenced by PFO, are prevalent in CADASIL and associated with a decline in quality of life and functional outcomes over time.

Background: Limited data exist on the significance of acute cerebral microinfarcts (A-CMIs) in the context of acute ischemic stroke (AIS). We aimed to determine the profile and prognostic significance of A-CMIs on magnetic resonance imaging (MRI) in patients presenting with AIS.
Methods: A prospective single-center series of patients with AIS who had 3T MRIs between March 2013 and December 2019.

Article Synopsis
- The study investigates how total sleep deprivation (TSD) impacts the functional organization of the brain, as measured by waking EEG in healthy males after a normal night's sleep versus after 24 hours of TSD.
- Researchers recorded EEG data from 18 participants, focusing on cross mutual information (A-CMI) between different cortical areas before and after TSD.
- Findings indicate that after 24 hours of TSD, there were significant decreases in A-CMI in specific brain area pairs, suggesting that lack of sleep disrupts the brain's cortical communication, particularly in regions related to frontal functions.
