Brain abscess in immunocompetent patients: recent findings

Area of Science:

• Neurology
• Infectious Diseases
• Neurosurgery

Background:

• Cerebral abscesses remain a significant clinical challenge with high mortality rates, despite advances.
• Epidemiology and management strategies require continuous updates for optimal patient care.

Purpose of the Study:

• To systematically review and update the current understanding of cerebral abscess epidemiology.
• To consolidate evidence on effective management strategies for cerebral abscesses in immunocompetent individuals.

Main Methods:

• Systematic literature review of observational studies.
• Analysis of parameters influencing prognosis and outcomes.

Main Results:

• Prognosis for cerebral abscess has improved, yet mortality remains high.
• Key factors for better outcomes include early diagnosis (MRI), appropriate neurosurgical/microbiological techniques, optimized antibiotic therapy, and long-term follow-up.
• Current evidence primarily relies on observational data.

Conclusions:

• A multidisciplinary approach is essential for optimizing acute and long-term management of cerebral abscesses.
• Urgent need for randomized controlled trials to identify interventions improving patient-centered outcomes.
