Abstract: The disproportion of the cerebrovascular response during brain activity is related to the etiology of migraine. Previous research tried to figure out if transcranialdoppler (TCD) might detect variations in brain flow velocity during the interictal phase of typical migraine. The goal of this review was to establish the diagnostic utility of transcranialdoppler (TCD) for variations in cerebral flow velocity during the interictal phase of various headache types. A comprehensive literature search was conducted on PubMed to find research that employed transcranial Doppler for distinct cerebral arteries in the interictal period; 15 articles were assessed, and ictal monitoring studies were discarded. we find increased in cerebral flow in migrainers and most frequent vessel with TCD abnormality was MCA then ACA, and lastly the PCA, As previously documented, higher flow velocity in migraine sufferers is thought to be due to arteriolar vasodilation rather than decreased lumen diameter in the insonated major arteries., increased neuronal excitability and neurovascular coupling in migraine. This altered visual processing in migraine patients and stronger changes in the MCA velocity can be used as prognostic tools, predicting more frequency of attacks with stronger CBFV changes.
