Meningo-encephalitis (manic psychoses), caused by meningitis pathogens, received the name meningo-occal in 1962. Meningioencephalitic syndrome is an acute or subacute infectious disease, which is a secondary reaction of the body in response to meningitis, sepsis, and other secondary purulent infections. MPS is treated with penicillin. In subacute forms of the disease, there is a regression of symptoms against the background of continued use of antibiotics.
