[Vertigo in neurological diseases].
Peripheral and central vestibular syndromes are characterized by the combination of the four symptoms such as: vertigo, nystagmus, imbalance and nausea. Vertigo is the disturbance of the cortico-spatial orientation. Nystagmus is regarded as a secondary symptom caused by direction specific disequilibrium of the vestibulo-ocular reflex. Imbalance is caused by the abnormal activation of vestibulo-spinal pathways. Nausea is due to the activation of the medullary vomiting center. It is important that clinicians can establish an adequate diagnosis and differentiate vertigo and dizziness. The author--without the aim of completeness--discusses the types of vertigo caused by the most important disorders of the central nervous system, emphasizing the role of general practitioners in the diagnostic and therapeutic algorhytm.
