“…As people age, the attachment between the periosteal layer of the dura mater and the bones of the cranium becomes firmer, making the dura less pliable. 128 A negative correlation was also found between dura mater thickness and aging, with older adults having a significantly thinner dura. 129 The arachnoid mater is one of the three meninge layers, located in between the dura and pia mater.…”

As individuals age, cognitive decline becomes more prominent, concomitant with an elevated susceptibility to neurodegenerative diseases and dementia. Additionally, symptoms of chronic neuropsychiatric diseases tend to worsen with age. It is crucial to highlight that the aging process does not affect individuals uniformly, and its effects can vary, even within the same person. This review aims to summary the impact of healthy aging on the human brain, focusing on the variations from different brain regions and cell types. Depending on specific brain regions, the brain exhibits thinning, volume reduction, regional shrinkage, disrupted tissue integrity, decreased cell complexity, or iron accumulation during aging. Moreover, the brain cells exhibit morphology and function changes during aging. Neurons undergo changes characterized by reduced dendrites, dendritic spines, and axons with less compact myelin sheaths, leading to a significant loss of synapses. Comparatively, glia often transform into a reactive phenotype.

“…The cavernous sinuses are bounded by meningeal and periosteal dura layers; the medial wall, being the weakest, consists of a single dural layer, while the other walls comprise both layers [18]. The cavernous sinus houses the ICA and its associated sympathetic plexuses, as well as cranial nerves II, III, IV, and V1 [19]. The cavernous sinus drains the superior and inferior ophthalmic veins, pterygoid plexus, Sylvian vein, and sphenoid parietal sinus into the superior and inferior petrosal sinuses.…”

Cerebrovascular complications from blunt trauma to the skull base, though rare, can lead to potentially devastating outcomes, emphasizing the importance of timely diagnosis and management. Due to the insidious clinical presentation, subtle nature of imaging findings, and complex anatomy of the skull base, diagnosing cerebrovascular injuries and their complications poses considerable challenges. This article offers a comprehensive review of skull base anatomy and pathophysiology pertinent to recognizing cerebrovascular injuries and their complications, up-to-date screening criteria and imaging techniques for assessing these injuries, and a case-based review of the spectrum of cerebrovascular complications arising from skull base trauma. This review will enhance understanding of cerebrovascular injuries and their complications from blunt skull base trauma to facilitate diagnosis and timely treatment.

“…The importance of other subarachnoid cisterns-the carotid, lamina terminalis, chiasmatic, pericallosal, crural, ambiens, and quadrigeminal and prepontine cisterns, and cisterna magna-are discussed in detail in the literature. 27 Beyond the subarachnoid cisterns, other neurosurgical landmarks are important for navigating the neural anatomy. One example of navigation by landmarks is using the relationship between the lateral mesencephalic vein and the mesencephalic sulcus.…”
