Thirty-four percent of 182 ischemic stroke patients registered during 1 year in a prospective hospital stroke data base complained of headache within a 72-hour interval of stroke onset. Headache was more common in patients under 70 years of age, in nonsmokers, in those with a past history of migraine, and in subjects presenting transient loss of consciousness, nausea/vomiting, or visual field defects. Headache was more frequent in vertebrobasilar (57%) than in carotid (20%) territory strokes, more so in posterior cerebral artery (90%) and cerebellar infarcts (80%), and was infrequent in subcortical infarcts (7%) and lacunes due to single perforator disease (9%). In multiple regression analysis, vertebrobasilar stroke (odds ratio 6.9), lacuanr stroke (odds ratio 0.06), and past history of migraine (odds ratio 6.7) were significant independent predictors of headache, suggesting that ischemic stroke location is the major determinant of stroke-associated headache, most probably related to activation of the trigeminovascular system, whose threshold may be modified by individual susceptibility.

The TIA concept is understood differently by neurologists and nonneurologists. GPs and emergency MDs often label minor strokes and several nonvascular transient neurological disturbances as TIAs. Until this misconception of TIA is changed, the term TIA should probably be avoided in the communication between referring physicians and neurologists. If not referred to a neurologist, one third to one half of patients labeled with a diagnosis of TIA will be inappropriately managed.

MD; for the TACIP InvestigatorsBackground and Purpose-The efficacy of the antiplatelet agent triflusal for prevention of vascular events after stroke has been reported in a pilot study. However, there is a need to confirm those results in a larger study. Methods-We performed a randomized, double-blind, multicenter study to test the efficacy of triflusal (600 mg/d) versus aspirin (325 mg/d) for prevention of vascular events in patients with stroke or transient ischemic attack (Triflusal versus Aspirin in Cerebral Infarction Prevention [TACIP]). We assessed a combined end point (incidence of nonfatal ischemic stroke, nonfatal acute myocardial infarction, or vascular death) as well as the incidence of these events separately and the incidence of major hemorrhage. Results-Of 2113 patients, 1058 received triflusal and 1055 aspirin. The mean follow-up period was 30.1 months. The incidence of combined end point (13.1% for triflusal, 12.4% for aspirin) as well the survival analysis (hazard ratio [HR] for triflusal versus aspirin, 1.09; 95% CI, 0.85 to 1.38) showed no differences between groups. The incidence of nonfatal stroke (HR, 1.09; 95% CI, 0.82 to 1.44), nonfatal acute myocardial infarction (HR, 0.95; 95% CI, 0.46 to 1.98,) and vascular death (HR, 1.22; 95% CI, 0.75 to 1.96) was also similar. A significantly higher incidence of major hemorrhages in the aspirin group was recorded (HR, 0.48; 95% CI, 0.28 to 0.82). The overall incidence of hemorrhage was significantly lower in the triflusal group (16.7% versus 25.2%) (odds ratio, 0.76; 95% CI, 0.67 to 0.86; PϽ0.001). Conclusions-This study failed to show significantly superior efficacy of triflusal over aspirin in the long-term prevention of vascular events after stroke, but triflusal was associated with a significantly lower rate of hemorrhagic complications.

The main factors influencing admission delay of stroke patients were investigated in 309 consecutive cases admitted to the emergency room of a University hospital. All these patients were examined and interviewed by a neurologist. Forty-two percent (117 patients) arrived within 6 h of the onset of symptoms. Extrahospital delay accounted for the largest fraction of time lost (82%), followed by intrahospital delay (16%) and transportation (2%). A medical contact prior to our hospital significantly delayed admission (mean delay 35 vs. 23 h, t = 1.82, p = 0.03). The percentage of strokes arriving within 6 h was higher (χ² = 5.8, p = 0.05), for those whose stroke started during ''working hours'' (09.00-18.00). Age and type of stroke (ischemic or hemorrhagic) did not have a significant influence on admission delay. Hoping that symptoms would clear, nonrecognition of stroke, refusal to go to the hospital, living alone and waiting for relatives were the most common alleged reason for not coming sooner. These results stress the need for educational intervention both for the public and the health professionals, focusing on urgent and direct referral of acute strokes to the hospital.

We aimed to describe and classify headaches associated with acute stroke, by interviewing patients consecutively admitted to a stroke unit using a validated headache questionnaire and the International Classification of Headache Disorders of the International Headache Society (IHS). One hundred and twenty-four patients (61% ischaemic and 39% haemorrhagic stroke) reported headache. Headaches started mostly on the day of stroke, were more often continuous, pressure-type, bilateral and located in the anterior region, were increased by movement and by cough and lasted for a mean of 3.8 days. Tension-type was the most frequent type of headache. Eleven per cent of headaches could not be classified using the criteria of the IHS. Previous primary headache was documented in 71 patients. The presence of nausea/vomiting due to acute stroke can confound headache classification using the IHS criteria. In up to half of the patients, headache seems to be a reactivation of previous primary headache.

qEEG indices are independent predictors of stroke outcome.

Hematoma location, meningeal signs, and gender are more predictive of headache than hematoma volume, suggesting that headache is more often related to the activation of an anatomically distributed system in susceptible individuals and to subarachnoid bleeding than to intracranial hypertension.

This study confirms that perimesencephalic haemorrhage is a distinct entity within the larger group of subarachnoid haemorrhage with negative angiograms, with a good short term and long-term prognosis, and no need for repeated angiographic investigation.
