My son had meningicoccal meningitis as a baby (6 months old). At the age of 12, he started exhibiting severe behavioral issues (running away, fighting with friends/family, drugs, drinking, etc.) and this trend has continued until now, at 16 years old. He cannot seem to maintain a relationship, he becomes very arrogant and hostile to people and he is erratic (moody). Could these symptoms somehow be linked with his meningitis as a child? We are at our wits end! Thank you...
