Clinical features of episodic migraine and transformed migraine: a comparative study

Abstract: -Transformed migraine (TM) is one of the most frequent types of chronic daily headache. Eighty patients: 40 with episodic migraine (EM) and 40 with TM with ages ranging from 18 to 60 years old were studied. Females were the majority. At first examination, the mean age was similar in both groups. The initial age of migraine attacks was significantly smaller in the TM group. Time history of episodic attacks was similar in both groups. In the EM group, the headache was predominantly located on only one side of th… Show more

“…These data showed a high occurrence of sleep-related migraine in a selected sample of migraineurs with low attack frequency (39% of the total sample of migraineurs), supporting previous literature data documenting that migraine attacks can preferentially occur during night sleep and/or upon awakening (Fox and Davis, 1998;Galego et al, 2002;Gori et al, 2012a;Kelman and Rains, 2005;Solomon, 1992). The relationship between migraine and sleep is complex and pluridirectional (i.e.…”

“…A preferential occurrence of attacks at night-time or in the early morning has been widely ascertained in migraine without aura patients. In particular, Galego et al (2002) documented that both episodic (55%) and chronic (62.5%) migraineurs reported waking up in the morning or being woken up during the night by headache, and subsequently Kelman and Rains (2005), in a study carried out in a larger sample of migraineurs (n=1283), found that 71% of patients exhibited morning headache on awakening (in 35% of the whole sample this was a very frequent or frequent occurrence, whereas in 36% it was occasional). Furthermore, a chronobiological study by Solomon (1992) found the occurrence of migraine attacks to be greatest between 6 a.m. and 10 a.m. and subsequent research by Fox and Davis (1998), looking for a circadian periodicity in the time of onset of 3,582 migraine headache attacks experienced by 1,698 patients, documented that onset of migraine without aura was most likely to occur between 4 a.m. and 9 a.m., the likelihood of its occurrence during this interval of time being far greater than at any other time of the day.…”

“…Excessive use of analgesics and ergotamine compounds; stress situation in the family or at work; traumatic life events; hypertension, birth control pills; abnormal personality profile and co-morbidity with some disorders such as anxiety and depression are factors linked with this transformation 11 . Galego et al 12 , based on clinical and demographic characteristics of episodic and transformed migraine, observed that earlier beginning of attacks might be a risk factor for transformed migraine. Taking into account the co-morbidity between migraine and depression, it is important for clinical practice to evaluate depressive symptoms as well as how their intensity is developed in patients with EM and TM.…”

“…In relation to CDH, Galego et al 28 found the emotional stress as the main precipitating factor (75%) of headache to transformed migraine. Stress is also mentioned as a development factor for CDH 6 .…”
