Symptoms of brain abscess may develop slowly, over a period of 2 weeks, or they may develop suddenly. The most common symptoms include fever, headache, and other neurological problems such as hemiparesis or aphasia.
Obtaining the history is the most important aspect of making a diagnosis of a brain abscess. A complete history will help determine the correct therapy and helps in determining the prognosis. Specific areas of focus when obtaining a history from the patient include:
- History of a clinical triad of fever, headaches, and focal neurological deficits
The symptoms of brain abscess are caused by a combination of increased intracranial pressure due to a space-occupying lesion (headache, vomiting, confusion, coma), infection (fever, fatigue etc.) and focal neurologic brain tissue damage (hemiparesis, aphasia etc.). The symptoms and findings depend largely on the specific location of the abscess in the brain.
Common symptoms of brain abscess include:
- Decreased movement
- Decreased sensation
- Decreasing responsiveness
- Fever and chills
- Loss of coordination and muscle function
- Visual disturbance
