A collection of pus in the brain caused by infection that may cause headaches, fever, and neurological symptoms.
For the 100% active-disease rating, medical records confirming that a brain abscess is currently present and under treatment are the core evidence. For residual ratings, the evidence depends on which symptoms remain. Neuropsychological or cognitive testing that shows objective impairment in memory, attention, concentration, or executive functions supports higher ratings in those areas; a complaint alone without test findings supports a lower level. Records documenting how often you become disoriented, how your judgment holds up in routine versus unfamiliar decisions, or how frequently your social behavior is inappropriate all tie directly to the criteria. For subjective symptoms, records or personal statements describing how headaches, dizziness, fatigue, or sensory sensitivities interfere with work or daily activities are relevant. For neurobehavioral effects such as irritability or aggression, statements from family members, coworkers, or treating providers describing how often those effects disrupt work or social interaction can help show the level of impairment.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
