The typical patient with VAD is a young person who experiences severe occipital headache and posterior nuchal pain following a head or neck injury and subsequently develops focal neurologic signs attributable to ischemia of the brainstem or cerebellum. The focal signs may not appear until after a latent period lasting as long as three days, however, and delays of weeks and years also have been reported. Many patients present only at the onset of neurologic symptoms.
