[Causes and diagnostics of dizziness of central origin in children]

Dizziness and vertigo are symptoms caused by several etiological factors, they are result of general diseases, within anemia. They are associated with several diseases of the organ of hearing and balance, which are under laryngological care, and one of most important tests to distinguish vertigo of central and peripheral origin is videonystagmography. Several diseases of the central nervous system cause instability of posture and gait. Psychogenic feeling of being insecure and unsafe makes the diagnostics more complicated. Vertigo of central origin in children can be a first symptom of severe conditions, such as tumor of CNS, therefore the neuroradiological evaluation is necessary for early diagnosis, before the occurrence of increase of intracranial pressure symptoms. Vascular diseases, such as vertebro-basilar insufficiency or stroke are diagnosed more common in adults, still they are not excluded in children, and therefore vascular evaluation is necessary. The cerebrovascular ultrasound is a method significant in the diagnostics as well as in the monitoring of therapy of cerebral vascular diseases. The elecrophysiological evaluation, EEG or videoEEG is useful in the evaluation of paroxysmal conditions. Evoked potentials are helpful in diagnostics of demyelination of CNC. The serological tests (within to detect boreliosis) are infrequently performed; they may lead to correct diagnosis and causal treatment. The paper presents examples of diagnostic methods valid in children with dizziness of central origin.
