Our previous research has determined that the vascular "cold patch" is a valid diagnostic "marker" and is a persistent constituent of the thermal geography of the external carotid region. It has been suggested by Dalla Volta and Anzola (1988) that the cold patch may be a prognostic index of
vascular headache
physiology; that is, as
headaches
improve through the use of vasoactive prophylactic medication, the cold patch would decrease in size or disappear. The purpose of this study is an attempt to replicate these findings. Forty migraine patients were randomly selected, and a thermographic re-examination of the external carotid region (forehead) was conducted. The post-treatment thermogram was then compared to the initial pre-treatment thermogram. Thirty subjects demonstrated an improved condition (IC) and ten subjects a worsened condition (WC). The IC Group exhibited a 73.2% reduction in
headache
frequency following a mean treatment period of 6.3 months. The WC Group demonstrated a 48.1% increase in
headache
occurrence at a mean treatment interval of fifteen months. Results demonstrated little thermographic difference between the two conditions. Within the IC Group, 46.7% of subjects exhibited and increase in cold patch size with an improved condition, 40% of cold patches remained stable, 6.7% of cold patches reduced in size, and zero cold patches disappeared with successful treatment. Within the WC Group, 20% of cold patches decreased in size with a worsened condition, 40% increased in size, and 40% remained stable. Chi square analysis determined there was no significant difference in cold patch changes between patients whose
headache
condition improved or worsened (p less than .70).(ABSTRACT TRUNCATED AT 250 WORDS)

Headache
associated with intracranial venous anomalies is well described but
headache
associated with extracranial venous malformation previously has not been recognized. A case of extracranial venous malformation producing
vascular headache
is presented.

Hand temperature norms are presented for 221
headache
patients (migraine, mixed, and tension), 105 hypertensives, 45 irritable bowel syndrome patients, and 56 normal controls under conditions of resting baseline, self-relaxation, volitional handwarming, mental arithmetic, and cold pressor. The two
vascular headache
groups (migraine and mixed) had significantly lower hand temperatures across conditions.

Sixty
vascular headache
sufferers who underwent a standard protocol treatment of progressive relaxation and thermal biofeedback with autogenic training were studied for changes in hand temperature (the targeted response) and heart rate (a non-targeted response) to determine how such physiological change relates to reduction in
headache
activity. Overall, regardless of degree of improvement, subjects showed a significant, positive change over time in their ability to increase hand temperature. It was also found that inability to handwarm at session one of thermal biofeedback training was predictive of treatment success, as was the ability to achieve a fingertip temperature of at least 96.0 degrees F at any point in thermal biofeedback training. In addition, it was found that migraine headache sufferers who were treatment successes had significantly lowered their heart rates from pre- to post-treatment assessment.

In most cases, patients presenting with "the worst
headache
ever" are found to have a benign condition, notably migraine, toxic
vascular headache
, or exertion-induced
headache
. However, ominous causes first must be excluded by appropriate investigation, such as computed tomographic or magnetic resonance imaging scans and lumbar puncture. When an ominous cause has been ruled out, appropriate therapy can be started.

Vascular
headaches
are among the most prevalent yet poorly understood problems in clinical neurology.
Headaches
may develop in association with hypertension, seizures, stroke or without a recognizable pathophysiology such as during migraine and cluster headaches. Cephalic blood vessels (pial and dural vessels) are implicated as the most important source for all
headaches
and are innervated by sensory fibers which arise from ganglia innervating the forehead, scalp and neck. Sensory fibers contain vasoactive neuropeptides which become released from peripheral (perivascular) and central terminations to mediate vasodilation and pain, respectively. The presence of
vascular headache
implies activation of this final common pain pathway which we have termed the trigeminovascular system. The presence of
vascular headache
implies activation of this final common pain pathway which we have termed the trigeminovascular system. The existence of such a system a) clarifies certain pain patterns which develop following stimulation of cephalic blood vessels, b) suggests a mechanism to explain the referral of pain to the forehead, c) provides a mechanism to explain the action of certain antimigraine drugs, d) suggests a local mechanism which enhances blood flow under certain pathological conditions. Hence, this review will update existing knowledge about the trigeminovascular system and its role in
headache
pathophysiology.

The aim of the work was to analyze circulatory, rheological, electrophysiological and psychological characteristics of patients with
vascular headache
, mostly migraine and vasomotor cephalea. The group was formed by 69 patients, mean age 40.4 +/- 9.0 years. It was revealed that: 1. there were no significant changes in rheological properties of blood in the following six parameters: coagulation, viscosity of plasma and blood, platelzo aggregation, of circulating aggregates, 2. there were no significant changes in rCBF (FF,SF,AF and ISI) parameters in the group of patients with bilateral
headache
but a rising rCBF in unilateral
headache
, 3. there was a significant reduction of the "peak frequency" in supratrochlear arteries and a significant increase of the flow rate in the intracerebral arteries (a.cerebralis media, a.cerebralis anterior), 42.4% of the patients displayed abnormal but non-specific EEg changes, 5. there was a significant increase of the amplitude of P1 and N2 waves of visual evoked potentials and a non-significant shortening of the latency of wave N1, 6. significant changes were recorded in some psychological parameters, in particular an increase of the score of depressivity, anxiety and neuroticism.

Vascular headache
of migraine-type may be a presenting symptom of multiple sclerosis (MS), a condition usually not considered in the differential diagnosis of a severe
headache
accompanied by neurological signs. We reviewed records of 1,113 patients with MS seen from 1967-1987 and found 44 cases whose initial attack or subsequent exacerbations were heralded by a migraine-type
headache
. Twenty-seven patients had no prior history of migraine, and of these, 12 presented simultaneously with their first
headache
and MS attack. Twenty-three patients had symptoms of a posterior fossa mass lesion. The significance of these results and possible pathogenesis is discussed.

A behavioral package was used to shape and maintain the adherence of 5 subjects with
vascular headache
to a program of aerobic exercise training. Repeated measures of exercise behavior were examined through the use of a bidirectional changing criterion design. Repeated measures of
headache
activity were also collected. Results demonstrated a functional relationship between the behavioral package and exercise adherence, because all 5 subjects showed exercise behavior that matched bidirectional changing exercise criteria. The results also indicated clinically significant collateral reductions in
vascular headache
activity in 4 subjects. Subjects whose aerobic fitness levels were not masked by vasoactive medication also showed measurable increases in aerobic fitness. The results are discussed in terms of the methodology used to demonstrate a functional relationship between the adherence package and exercise behavior and the possible mechanism(s) by which aerobic exercise activity might affect
vascular headache
activity.

From a consecutive series of 3,847
headache
patients, 1,331 patients who made first visits for new
headache
to 120 primary care physicians were studied for usual care over a 14-month period. Either tension or
vascular headache
was the initial diagnosis in 23.8 percent and 12.8 percent of patients, respectively. Nearly one half (47.8 percent) were classified as having
headaches
other than tension or vascular. A total of 15.3 percent of
headaches
were undiagnosed or were regarded as a mixture of traditional diagnostic designations. At first visit, most patients (76.6 percent) were managed without diagnostic tests. Drugs were prescribed for 73.6 percent, and advice was given for 58.6 percent. Only 2.0 percent of patients had computerized tomographic scanning ordered at first visit, although at least 46 percent met National Institutes of Health criteria, a finding with potential economic consequences of at least $2 billion. These findings suggest the need for reevaluation of diagnostic categories for
headache
, reevaluation of strategies for
headache
management, and further investigations of
headache
in primary care patients.
