3. An arachnoiditis. At 12 patients the arachnoiditis has developed after the transferred infections (respiratory diseases, quinsy), at 21 th background torpently flowing , a genyantritis, a frontal sinusitis, an otitis.
At 19 persons basal localisation of process, at 14 - is noted.
At 12 the form, at 5-cystic, at 16 - admixed is diagnosed . The diagnosis is established on the basis of anamnesis data (a previous infection, torpently current focal inflammatory process) and data of objective research (symptoms of a focal lesion of a brain, an illegibility of borders or puffiness of disks of optic nerves, abaissement of fields of vision, changes on the pneumoencephalogram).
4. A myelitis. At 2 patients the myelitis has developed at height of the respiratory disease proceeding with a heat.
5. A polyneuritis. With a polyneuritis we observed 45 patients, from them at 28 it has developed after respiratory infections, at 12 - after quinsy, at 3 - after a pneumonia, at 1 - after a dysentery and still at 1 - against an erysipilatous inflammation of an anticnemion.
Thus, our observations basically coincide with data of the literature on frequency and character of the neuroinfections meeting now. Separate forms of an encephalitis, a meningitis, a myelitis are most difficult for diagnostics. In any measure the establishment of the correct diagnosis can be promoted by such indirect signs, as seasonal prevalence of disease and some specific symptoms (drowsiness, a hypersalivation etc.).
