Pterional vs. mini-pterional craniotomy for intracranial aneurysms: a systematic review and meta-analysis.

The mini-pterional craniotomy (mPT) was designed to be a minimally invasive alternative to the standard pterional (PT) approach. However, it remains unclear which technique produces better results. Thus, we aimed to perform a meta-analysis comparing functional, surgical, and aesthetic outcomes between mPT and PT in intracranial aneurysms.

Background: The Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, is one of the biggest health concerns of the century. Long COVID is one of the major sequelae from the infection and include persistent neurological manifestations. Brain images study suggest that Long COVID patients present distinct brain metabolic alterations.

Background: The COVID-19 pandemic is a public health crisis, and its lasting consequences are not yet fully understood. Epidemiological data suggest that low- and middle-income countries, such as Brazil, will bear a considerable burden of COVID-19-related comorbidities. Individuals who have survived COVID-19 often report persistent symptoms, including neurological manifestations such as brain fog.

Background: A rare reelin gene variant (RELN-COLBOS mutation) delayed dementia onset in almost 30 years in an autosomal dominant Alzheimer's disease (ADAD) carrier. This patient presented with high amyloid-β (Aβ) plaque load, but low tau accumulation, suggesting that this single-nucleotide polymorphism (SNP) in RELN conferred a resilience not only to cognitive decline but also to tauopathy in ADAD. However, whether RELN SNPs are also protective in sporadic Alzheimer's disease (AD) is yet to be determined.

Background: Microglial activation is an early phenomenon in Alzheimer's disease (AD) that may occur prior to and independently of amyloid-β (Aβ) aggregation. Compelling experimental evidence suggests that the apolipoprotein E ε4 (APOEε4) allele may be a culprit of early microglial activation in AD. However, it is unclear whether the APOEε4 genotype is associated with microglial reactivity in the living human brain.
