Introduction: Long-term systolic blood pressure variability (BPV) has been proposed as a novel risk factor for dementia, but the underlying mechanisms are largely unknown. We aimed to investigate the association between long-term blood pressure variability (BPV), brain injury, and cognitive decline in patients with mild cognitive symptoms and cerebral amyloid angiopathy (CAA), a well-characterized small-vessel disease that causes cognitive decline in older adults.
Methods: Using a prospective memory clinic cohort, we enrolled 102 participants, of whom 52 with probable CAA.
Background And Objectives: Accumulating evidence suggests that gray matter atrophy, often considered a marker of Alzheimer disease (AD), can also result from cerebral small vessel disease (CSVD). Cerebral amyloid angiopathy (CAA) is a form of sporadic CSVD, diagnosed through neuroimaging criteria, that often co-occurs with AD pathology and leads to cognitive impairment. We sought to identify the role of hippocampal integrity in the development of cognitive impairment in a cohort of patients with possible and probable CAA.

Methods: We randomly selected 10 patients with brain gliomas discussed at our institution's central nervous system tumour board (CNS TB). Patients' clinical status, surgical outcome, textual imaging information and immuno-pathology results were provided to ChatGPT V.
A large interventional trial, the Systolic Blood Pressure Intervention Trial sub-study termed Memory and Cognition in Decreased Hypertension (SPRINT-MIND), found reduced risk of cognitive impairment in older adults with intensive, relative to standard, blood-pressure-lowering targets (systolic BP < 120 vs. <140 mm Hg). In this perspective, we discuss key questions and make recommendations for clinical practice and for clinical trials, following SPRINT-MIND.

Its diagnosis remains a challenge for the clinician because of the variety of clinical presentations and comorbidities. The diagnosis is based on clinical criteria such as cognitive fluctuations, visual hallucinations, progressive cognitive impairment, Parkinsonian signs and REM sleep behavioral disorder.

CAA causes devastating outcomes related to intracerebral hemorrhage and cognitive decline in older adults. The shared pathogenic pathway between CAA and Alzheimer's disease, co-occuring frequently in the same subject, has important implications for cognitive outcomes and novel anti-amyloid-β immunotherapies.

In this article, we propose a pragmatic approach for the diagnosis and treatment of rare causes of cerebral small vessel disease.

Methods: Thirty-seven participants with probable sporadic cerebral amyloid angiopathy without symptomatic intracranial hemorrhage or dementia (mean age, 73.3 ± 7.
A leading cause of white matter (WM) injury in older individuals is cerebral small vessel disease (SVD). Cerebral SVD is the most prevalent vascular contributor to cognitive impairment and dementia. Therapeutic progress for cerebral SVD and other WM disorders depends on the development and validation of neuroimaging markers suitable as outcome measures in future interventional trials.

Purpose: Investigate whether PSMD (1) is higher in patients with Cerebral Amyloid Angiopathy (CAA) than those with arteriolosclerosis; (2) can capture the anteroposterior distribution of CAA-related abnormalities; (3) shows similar neuroimaging and cognitive associations in comparison to other classical DTI markers, such as average mean diffusivity (MD) and fractional anisotropy (FA).
Materials And Methods: We analyzed cross-sectional neuroimaging and neuropsychological data from 90 non-demented memory-clinic subjects from a single center.
Background: Emergency medical services (EMS) are the first health care contact for the majority of stroke patients. However, there is a lack of data on the current paramedics’ hospital-directed feedback and training needs across different health care settings. We aimed to evaluate paramedics’ prehospital stroke care knowledge, training needs, and current status of feedback on suspected stroke patients.

We aimed to assess the effect of interactive emergency medical services (EMS) training on stroke recognition and prehospital care performance in a very high-risk cardiovascular risk population in Lithuania.
Methods: We conducted a single-center interrupted time-series study between March 1, 2019 and March 15, 2020.
Background: Glioblastoma is the most common and the most challenging to treat adult primary central nervous system tumor. Although modern management strategies modestly improved the overall survival, the prognosis remains dismal associated with poor life quality and the clinical course often dotted by treatment side effects and cognitive decline. Functional deterioration might be caused by obstructive or communicating hydrocephalus but due to poor overall prognosis surgical treatment options are often limited and its optimal management strategies remain elusive.

In clinical trials, amyloid-β immunotherapy has been associated with a high rate of amyloid-related imaging abnormalities, potentially driven by coexisting cerebral amyloid angiopathy. Therefore, immunotherapy's efficacy in patients may be modified by coexisting cerebrovascular pathology.

We aimed to investigate SoT incidence, clinical spectrum, risk factors, and the impact of the cranioplasty on neurologic recovery. Patients undergoing a large craniectomy (> 80 cm) and cranioplasty were prospectively evaluated using modified Rankin score (mRS), cognitive (attention/processing speed, executive function, language, visuospatial), motor (Motricity Index, Jamar dynamometer, postural score, gait assessment), and radiologic evaluation within four days before and after a cranioplasty.

The impact of COVID-19 lockdown on prehospital stroke care is largely unknown. We aimed to compare stroke care patterns before and during a state-wide lockdown. Thus, we analysed prospective data of stroke alerts referred to our stroke centre between 1 December 2019 and 16 June 2020, and compared them between two periods-15 weeks before and 13 weeks during the state-wide lockdown declared in Lithuania on 16 March 2020.

We further address available management and therapeutic strategies.
Recent Findings: Vascular and neurodegenerative pathologies often co-occur and share similar risk factors.
Background: Cortical superficial siderosis (cSS) is a hemorrhagic marker of blood-brain barrier disruption detected in brain MRI. Together with cerebral microbleeds (CMB), they are recognized as a small vessel disease marker associated with cerebral amyloid angiopathy.
Objective: This study aims to determine the prevalence and the characteristics of cSS in a memory clinic population.
Objective: The prediction of verbal memory decline after temporal lobe epilepsy (TLE) surgery remains difficult at an individual level. We evaluated the prognostic value of postictal memory testing in predicting the postoperative verbal memory function.
Methods: Sixty-three consecutive patients were included in the analysis who underwent TLE surgery at our center with preoperative interictal/postictal and postoperative memory testing.
Background: Patient safety aspects and the residents' role in spine surgery within a structured training program have recently been investigated. The current work deals with residency training safety aspects for cranioplasty (CP), a standard neurosurgical cranial procedure.
Methods: Retrospective 2-center study comparing consecutive patients undergoing CP by a supervised neurosurgery resident (teaching cases) with a consecutive series of patients operated on by a board-certified faculty neurosurgeon (nonteaching cases).
