The analysis group means that the seemingly motion of antidopaminergic antiemetics on the stream of blood to the mind might be the explanation for this elevated threat.

Antidopaminergic antiemetics are antidopaminergic medication like antipsychotics that work by blocking the exercise of dopamine within the mind. Antipsychotics have been linked to greater ischemic stroke threat, however whether or not or not this threat might apply to different antidopaminergics corresponding to antidopaminergic antiemetics is unknown.
