Diagnosis of migraine headache.

JOURNAL ARTICLES:

A transcranial doppler study in interictal migraine and tension-type headache. (J Clin Ultrasound. 2007) "CONCLUSION.: Our findings support the arteriolar vasodilatation theory in migraine without aura."

Applying the International Classification of Headache Disorders to the Emergency Department: An Assessment of Reproducibility and the Frequency With Which a Unique Diagnosis Can be Assigned to Every Acute Headache Presentation. (Ann Emerg Med. 2007)

Assessment of headache diagnosis. A comparative population study of a clinical interview with a diagnostic headache diary. (Cephalalgia. 2007)

Characteristics of brain tumour-associated headache (Cephalalgia 2007) "Eighty-five brain tumour patients were examined for further characteristics of brain tumour-associated headache. The overall prevalence of headache in this population was 60%, but headache was the sole symptom in only 2%. Pain was generally dull, of moderate intensity, and not specifically localized. Nearly 40% met the criteria of tension-type headache. An alteration of the pain with the occurrence of the tumour was experienced by 82.5%, implying that the pre-existing and the brain tumour headaches were different. The classic characteristics mentioned in the International Classification of Headache Disorders (worsening in the morning or during coughing) were not found; this might be explained by the patients not having elevated intracranial pressure."

The differential diagnosis of chronic daily headaches: an algorithm-based approach. (J Headache Pain. 2007) "Chronic daily headaches (CDHs) refers to primary headaches that happen on at least 15 days per month, for 4 or more hours per day, for at least three consecutive months. The differential diagnosis of CDHs is challenging and should proceed in an orderly fashion. The approach begins with a search for "red flags" that suggest the possibility of a secondary headache."

Voxel-Based Morphometry Reveals Gray Matter Abnormalities in Migraine (Headache: The Journal of Head and Face Pain 2007) "Conclusions.—Our study shows that migraine is associated with a significant gray matter reduction in several of the cortical areas involved in pain circuitry. In addition, we found a significant correlation between frequency of migraine attacks and signal alteration in the Anterior Cingulate Cortex. Our data provide new insight into migraine pathophysiology and support the concept that migraine may be a progressive disorder."
