Summary: This study compared the use of DSC-MRI and FDG-PET in the diagnosis of AD and aMCI. Results showed that hypoperfusion was present in AD patients, while aMCI patients showed hypoperfusion in the parietal and temporal cortices, as well as the left PCG region. FDG-PET was more accurate in distinguishing aMCI from the control group. DSC-MRI may be a competitive method to FDG-PET.

Summary: Through the investigation of patients with mild cognitive impairment with Lewy bodies (MCI-LB), it was found that MCI-LB patients have more symptoms, and a 10-point symptom scale can effectively differentiate MCI-LB and MCI-AD. These findings are important for clinicians to diagnose and treat MCI.

Summary: This study evaluated serum ApoJ levels in 196 MCI subjects and found that low ApoJ levels may be associated with an increased risk of developing dementia. The risk of dementia conversion doubled in subjects with lower ApoJ levels compared to those with higher levels, especially after two years of follow up.

Summary: This study compared total cerebral blood flow (tCBF), global cerebral perfusion (GCP), and volumes of AD-prone regions between cognitively normal and early amnestic mild cognitive impairment (aMCI) individuals. It was found that tCBF and GCP were significantly reduced in the early aMCI group compared to the cognitively normal group. Furthermore, tCBF and GCP were significantly associated with global cognition and memory scores.

Summary: The study found significant differences in neuroimaging abnormalities between amnestic mild cognitive impairment (aMCI) and nonamnestic mild cognitive impairment (naMCI), with aMCI showing more and more significant abnormalities, while naMCI showing more limited abnormalities, with shared features but unique neuroimaging abnormalities in aMCI.

Summary: Suboptimal sleep can lead to cognitive decline and accelerate Alzheimer's Disease progression. Early intervention in MCI and mild AD is necessary, but there is a lack of evidence for sleep interventions in these stages, highlighting the need for high quality experimental studies exploring alternative interventions.

Summary: Exposure to outdoor air pollutants, particularly PM10, may nonlinearly increase the risk of conversion from MCI to dementia. Higher PM10 levels were associated with increased concentrations of cerebrospinal fluid tau proteins and decreased beta-amyloid levels. The risk of dementia was positively associated with mean PM10 levels above 10 μg/m3 and maximum PM10 levels above 35 μg/m3.

Summary: Dynamic cerebral autoregulation (dCA) is a key mechanism that regulates cerebral blood flow in response to transient changes in blood pressure. The literature remains conflicted on whether dCA is altered in Alzheimer's disease (AD) and mild cognitive impairment (MCI). A qualitative synthesis of eight studies suggests no significant difference in dCA parameters for spontaneous fluctuations between AD, MCI, and healthy controls. Limited data on induced fluctuations indicate preserved or possibly better autoregulatory functioning in AD and MCI compared to controls. Further research is needed to investigate dCA in dementia with induced fluctuations controlling for changes in end-tidal carbon dioxide.

Summary: The study compared resting-state fMRI data of patients with mild cognitive impairment due to Lewy bodies and Alzheimer's disease, finding no significant differences between the mild cognitive impairment groups and controls. The fMRI analyses did not appear sensitive enough to detect early and subtle changes in brain function in these patients.

Summary: The study used EEG-fMRI to evaluate brain activity in patients with mild cognitive impairment (MCI) and found abnormal coupling in multiple networks in MCI patients. Amyloid deposition was associated with abnormal signal coupling in visual, fronto-parietal regions, and some core memory regions.

Summary: This study compared clinical and biomarker features between A+T+MCI individuals progressing to pMCI and those remaining stable sMCI, identifying CSF and cognitive measures at baseline predictive of dementia progression within 2 years. Subset differences in biomarkers, cognitive assessment, and MRI imaging were observed, with CSF t-tau levels and cognitive scores serving as potential risk factors for dementia progression in A+T+MCI individuals.

Summary: The study tested the performance of the LBD-MOD module in characterizing Lewy body dementia (DLB) and distinguishing it from Alzheimer's disease (AD). Results showed differences between DLB and AD in various symptoms, as well as differences between MCI-DLB and MCI-AD. The LBD-MOD module provided excellent characterization of core features and supportive features to differentiate DLB from AD and also characterize features of MCI-DLB.

Summary: This theoretical review critically examines linguistic and semantic processing in Mild Cognitive Impairment and Alzheimer's disease, focusing on a neurobiological perspective. The authors propose that most linguistic alterations result from inhibited semantic discrimination, caused by a cluster of cholinergic dysfunction, A?? load, and somatostatin-positive cell loss. These changes lead to failures in accurate retrieval, verbal fluency anomalies, semantic interference, dampened N400 effects, and other semantic deviations.

Summary: The study investigated the deposition of lanthanum in two patients who received lanthanum carbonate as a phosphate binder, compared to additionally found gadolinium deposition. Both lanthanum and gadolinium were found to deposit in various tissues of the body, with a significantly increased Gd-to-La ratio in certain organs like the thyroid vasculature and cerebellum.

Summary: The required amount of ICM for CT can be reduced by 50% while maintaining image quality and diagnostic accuracy using GANs. The networks achieving 50% reduction in ICM dose reached 100% consistency in the crucial question of pathological consistency. More studies are needed to confirm these initial results.

Summary: The study found that the administration of intra-arterial fibrinolytics as an adjunct to mechanical thrombectomy is rarely performed but can improve reperfusion, leading to better treatment outcomes. However, there is a possible increased risk of symptomatic intracranial hemorrhage, highlighting the importance of careful patient selection.

Summary: Studying preoperative laboratory inflammation markers in melanoma patients with brain metastasis undergoing surgery revealed that elevated CRP levels, higher NLR and PLR, and lower LMR were associated with reduced overall survival rates. These markers could potentially be integrated into preoperative treatment planning for affected patients.

Summary: Surgical resection is effective for treating tumor-related epilepsy in patients with brain metastases, although some patients may experience postoperative persistent epilepsy. Identifying preoperative risk factors for unfavorable seizure outcomes is crucial, with tumor volume, midline shift, and necrosis/tumor volume ratio being significant factors. Preoperative identification of these factors can help in selecting highly vulnerable patients who may benefit from neuro-oncological expertise during treatment.

Summary: The study aimed to compare and combine the diagnostic performance of ADC from DWI and PDFF from CSE-based MRI in distinguishing benign and malignant vertebral bone marrow lesions. Results showed that ADC and PDFF values were significantly lower in malignant lesions compared to benign lesions, and the combination of both parameters improved diagnostic accuracy in differentiating benign and malignant VBMLs, yielding a high diagnostic accuracy.

Summary: This study aimed to generate virtual STIR (vSTIR) images from non-contrast, non-fat-suppressed T1- and T2-weighted images using a conditional generative adversarial network (cGAN) to shorten scanning time in MRI of the spine. Validation tests showed that vSTIR was equivalent to real STIR in most cases, with only slight insignificant differences in some details.
