By Mayo Clinic staffThe complications of meningitis can be severe. The longer you or your child has the disease without treatment, the greater the risk of seizures and of permanent neurological damage, including hearing loss, blindness, loss of speech, learning disabilities, behavior problems and brain damage, even paralysis.
Non-neurological complications may include kidney failure and adrenal gland failure. Your adrenal glands produce a number of important hormones including cortisol, which helps your body deal with stress.
Bacterial infections of your central nervous system progress quickly. Within a matter of days, the disease can lead to shock and death.
