ABSTRACT
Investigation of the bioelectrical activity and cerebral blood content has shown different changes in the baseline EEGs and REGs in children with acute serous meningitis. The visual assessment of the EEGs revealed in 52% of cases paroxysmal activity, diminished regularity of the dominant rhythm, etc. The findings of the cross-correlation analysis indicated impairment of the space-time organization of the potentials: there was a reduction in the functional activity of the anterior associative structures, particularly in the left hemisphere, and lagging of the electrical processes in the frontal zones of the right hemisphere from potentials of other centres. Changes in the cross-correlational functions of biopotentials were attended by alterations in the REG parameters, in particular by a decreased amplitude of the pulse wave, elevated vascular tone and increased interhemispherical asymmetry. The role of intracranial hypertension in the genesis of identified disorders is discussed.

The results of balneotherapy in patients with cerebroasthenic and hypertensive syndromes are described. Twenty-four children were examined electrophysiologically and neuropsychologically before and after sanatorium treatment. Massage, exercises, drug therapy, radon and carbon dioxide and sulfurated hydrogen baths were used. Sanatorium treatment resulted in a significant improvement of the general condition, of bioelectrical cerebral activity, of brain hemo- and CSF-dynamics as well as in the recovery of cortical functional activity. The most effective and stable results were obtained in patients with a favourable premorbid period of meningitis. Children with meningitis which occurred after an aggravated premorbid period needed repeated treatment courses.

A comprehensive examination of children aged one to 12 years suffering from epidemic parotitis (mumps) was carried out. Changes on the electro-, rheo-, and echoencephalograms were revealed, these changes depending on the form (glandular or glandular-nervous) and the period of the disease. The most pronounced disturbances were noted in the acute period of the disease in children with the glandular-nervous form of parotitis. As the children recovered the EEG, REG and echo-EEG findings in most of them still remained abnormal. This shows that the epidemic parotitis virus affects the nervous system.

Studies on animals demonstrated that in experimental herpetic encephalitis there is a diffuse retardation of background bioelectric brain activity and a proxysmal activity of 2 types: peek complex-slow waves 3 per 1 sec. and periodical paroxysmal complexes. There is also an increase of latent periods, duration and amplitudes of visual evoked potentials. Electrophysiological data correlate with the clinical picture of herpetic encephalitis and pathomorphological changes in the CNS. The obtained data are discussed with consideration bor the theory of neuron epileptization and hemodynamical disturbances.

Examinations carried out on 33 rabbits with an experimental herpetic encpehalitis showed changes in the electrical activity of the brain correlating with the clinical picture of the disease. A diffus slowing down of the biopotentials and paroxysmal activity of two types--the paroxysmal periodic complexes and the complexes 'spike +the paroxysmal 3/sec' was revealed during the acute period of encephalitis.
