Answer

Based on the temporal profile of the symptoms, basilar artery thrombosis may manifest in at least these 3 different ways, as follows:

  • Sudden onset of severe motor and bulbar symptoms with impaired consciousness

  • Gradual or stuttering course of a combination of the symptoms described above that ends with disabling motor and bulbar symptoms, impaired consciousness, or both

  • Prodromal symptoms that may include loss of vision, diplopia, dysarthria, vertigo, hemiparesis, paresthesias, imbalance, and convulsive-like movements (these symptoms may precede monophasic basilar artery thrombosis by several days or even by months)
