an inflammatory condition (-itis) of the meninges (mening/o, meningi/o) that affects the brain and spinal cord. Infecting agents—for example, bacteria (in pyogenic meningitis), viruses (in aseptic or viral meningitis), and fungi—enter the central nervous system through the bloodstream or as a consequence of an upper respiratory infection. This invasion causes acute inflammation of the pia mater and arachnoid membrane.
Symptoms of meningitis include severe headache, fever, and neck stiffness, or nuchal rigidity, as seen in this infant. Deafness, blindness, paralysis, and mental retardation are among the possible residual effects
a neurologic condition that appears to be associated with an excess of, or hypersensitivity to, dopamine. It is characterized by facial grimacing, tics (the spasmodic blinking and twitching of facial muscles), and involuntary arm and shoulder movements. Abnormal (dys-) involuntary, spasmodic movements (kinesi/o, kines/o, -kinesia, -kinesis) are called dyskinesia. The person with Tourette syndrome may also grunt, snort, or shout obscenities
