Brain abscess (BA) can lead to lasting cognitive deficits and affect quality of life in many patients. These long-term effects often present as diffuse subcortical impairments, not solely related to the initial lesion site.

Area of Science:

  • Neurology
  • Neuropsychology

Background:

  • Brain abscess (BA) consequences on cognition and behavior are not well-documented.
  • Understanding long-term deficits is crucial for patient management and rehabilitation.

Purpose of the Study:

  • To investigate long-term cognitive deficits following brain abscess.
  • To assess the impact of brain abscess on patients' quality of life.

Main Methods:

  • Neuropsychological and behavioral testing of 20 patients 6 months to 42 years post-brain abscess.
  • Comparison of patient performance against healthy, age, sex, and education-matched controls.
  • Definition of cognitive deficits based on scores 2+ standard deviations below the control mean.

Main Results:

  • 65% of patients (13/20) exhibited neuropsychological deficits.
  • 50% of patients had impairments in 1-2 cognitive domains; 15% had impairments in 3-5 domains.
  • No correlation found between impairments and patient age, sex, lesion characteristics, or seizures. 25% reported reduced quality of life.

    • Conclusions:

    • Brain abscess can cause persistent, long-term cognitive deficits.
    • Sequelae often manifest as diffuse subcortical deficits, irrespective of the focal nature of the initial lesion.
    • Brain abscess significantly impacts cognitive function and quality of life in a substantial patient group.
