Final answer:
Cerebral edema is the complication of bacterial meningitis that can cause seizures resistant to anticonvulsant treatment due to increased intracranial pressure from the swollen brain tissue.
Step-by-step explanation:
The complication of bacterial meningitis that can cause seizures resistant to anticonvulsant treatment is likely due to cerebral edema. This condition occurs as a result of the inflammation caused by the infection, leading to swelling of the brain tissue and an increase in intracranial pressure. This swollen brain tissue has limited space to expand within the confines of the skull, which can be problematic and cause severe neurological issues, including seizures that do not respond well to treatment. Meningitis is the inflammation of the meninges, and in cases where the brain tissue gets inflamed, it is referred to as encephalitis. If both the meninges and the brain are inflamed, it is known as meningoencephalitis. Treating bacterial meningitis typically involves antibiotics, but complications arising from the disease, such as cerebral edema, may require additional interventions.
