Improved surgical techniques and better understanding of neuroanatomy has enabled safe and effective treatment of brain abscesses. The past few decades have seen a drastic change in the epidemiology of brain abscesses. Brain abscesses are potentially fatal, focal cerebral lesions of infective etiology. The etiological agents of brain abscess have undergone an epidemiological shift.
The widespread implementation of vaccinations and availability of improved antibiotic therapy has caused a reduction in brain abscesses due to organisms causing otitis or sinusitis.
