Brain reserve is an important concept to understand the variability of damage associated with brain-related diseases and includes the adaptation of cognitive processes to preserve brain function. A good cognitive reserve might delay the onset of clinical manifestations of neurodegenerative diseases as well as hepatic encephalopathy, improving the quality of life in patients with chronic liver diseases. By stimulating activities and maintaining overall health, individuals may be able to enhance their brain's resilience to age-related changes and pathology.

Article Synopsis
  • The zygomatic bone, crucial in facial anatomy, is prone to fractures from impacts like accidents and sports, and zygomatic implants may increase this risk.
  • A complex anatomical model using finite-element analysis (FEM) was created to simulate the zygomatic bone's behavior under various impact velocities.
  • Results indicated that higher speeds (15 and 20 km/h) caused severe crush fractures, while lower speeds led to less severe local damage, highlighting specific high-stress areas crucial for injury prevention.
