CGRP (calcitonin gene-related peptide) is a potent vasodilator neuropeptide which acts on peri-arteriolar neurones and is implicated in the pathogenesis of numerous cardiovascular diseases. The synthesis of CGRP antagonists should be useful for the treatment of Raynaud's disease as well as migraine. There exists an homology between the structures of CGRP and pancreatic amylin and therefore an eventual role of CGRP in type II diabetes pathophysiology is currently being studied.

The association between major depressive disorder (MDD) and self-reported histories of specific physical illnesses was investigated in 320 controls and 1968 first-degree relatives and 254 spouses of probands in the NIMH Collaborative Depression study. The Schedule for Affective Disorders and Schizophrenia-Lifetime Version was used to assign Research Diagnostic Criteria (RDC) diagnoses and a structured self-report instrument was used to assess lifetime medical history. Lifetime MDD was diagnosed in 914 subjects, 402 of whom had been hospitalized or received somatic treatment ('treated' MDD). Strong associations were observed between MDD (either treated or untreated) and both frequent/severe headaches and migraine headaches. There was a marked gender effect such that the relative odds for a woman with treated MDD to report migraine were over 5:1. Other associations were found between MDD and skin infections, respiratory illness, ulcer, hypotension, and diabetes. This is the largest non-patient sample using standardized assessment of mental disorders by direct interview in which associations between specific physical illnesses and MDD have been demonstrated. Implications for clinical practice and neurobiological research in depression are discussed.

The clinical manifestations of mitochondrial encephalomyopathy are described in four generations of a single kindred. The age of onset of major neurological disturbance varied from 3-70 years. In some patients, deafness was the only manifestation; in others, recurrent bouts of status epilepticus associated with focal neurological deficits and headache, caused severe disability or death. Examples of all three adult forms of mitochondrial encephalomyopathy: MELAS, MERFF and Kearns Sayre syndrome, were represented within the kindred. Associated features included deafness, short stature, non-insulin-dependent diabetes mellitus, migraine, peptic ulceration and severe constipation. The nt 3243 A-G MELAS mutation was detected in two members of the kindred. This study highlights the diversity of clinical expression of a mitochondrial mutation within a single kindred.

To be consistent with a diagnosis of TIA or stroke, a focal neurologic deficit must have occurred suddenly. The differential diagnosis of TIA includes migraine aura (possibly without a headache), a hypotensive episode, radiculopathy, and an unusual seizure. Vascular risk factors (eg, hypertension, diabetes, smoking) and the extent of their control should be determined. Cardiac examination and ECG may provide important clues, as atrial fibrillation and valvular heart disorders are well recognized potential sources of emboli. During an acute stroke, CT is the best test to reliably distinguish between ischemic and hemorrhagic stroke. Other tests that may be indicated on an individual basis include MRI,, echocardiography, carotid duplex ultrasound, and arteriography.

Transient global amnesia (AGT) is a well-defined syndrome of unknown aetiology. It is generally believed to be of vascular origin. Other theories suggest epilepsy or migraine as the cause. We studied the clinical features and associated risk factors in 24 patients with AGT, comparing them with two control groups with 24 people in each group, paired for age and sex. The first control group contained healthy individuals (CN) and the second patients with transient ischaemic attacks (AIT). Of the patients with AGT, 70% were women and 30% men. Their average age was 60 (range 14-76). The attacks were abrupt in onset in 100%. In 8% there was a recognisable trigger factor (driving, physical exercise, etc). The average duration was 7 hours. On study of the cardiovascular risk factors, it was found that 36% were hypertensive, 24% had cardiopathy, 12% had diabetes mellitus, 8% were smokers, 4% had polycythaemia, 16% had hyperlipidaemia, 4% were alcoholics. There was a history of migraine in 29%. No patient had a past history of epilepsy. Further investigation showed ECG changes in 12%. In 24% there were non-specific changes in the EEG. On cerebral CT scan there were lesions compatible with ischaemia in 12.5% of the patients. Levels of arterial hypertension were significantly higher in the AGT group as compared to the normal control group (Odds ratio 7.86; CI. 1.29-11.38). A past history of migraine was seen to be a risk factor associated with AGT as compared with both groups of controls (AGT/CN Odds ratio 9.47; CI 1.01-444.92; AGT/AIT Odds ratio > 1.72).

A rare point mutation at nucleotide position 8356 in the transfer RNA gene in mitochondrial DNA was found in a Japanese family. Our proband had migraine and dementia associated with lactic acidosis in addition to myoclonic epilepsy with ataxia and ragged-red fibres in a muscle biopsy specimen consistent with the clinical characteristics of myoclonic epilepsy with ragged-red fibres (MERRF). His mother, who had the same point mutation, also had migraine but without myoclonus or ataxia. His aunt, who had the same point mutation and migraine, developed diabetes mellitus, encephalomyopathy and several stroke-like episodes associated with lactic acidosis (MELAS). This is the third family with the rare mutation seen in American and Italian families. The mutation may not be specific to Caucasians, and is probably closely related to the MERRF/MELAS overlap syndrome.

Calcitonin gene related peptide (CGRP), a potent vasoactive and cardiotonic peptide, interacts with specific G-protein-coupled receptors. CGRP is synthesized and released from small, capsaicin-sensitive sensory nerves. This extensive network of sensory nerves, found in virtually all organs, suggest a potential role for CGRP in diverse physiologic and pathophysiologic processes. The potent vasodilation elicited by CGRP in the cerebral, coronary, and peripheral vasculature has led to its therapeutic evaluation in the treatment of cerebral vasospasm following subarachnoid hemorrhage, stable angina, and Raynaud's phenomenon. The potential inotropic action and coronary vasodilation have also led to a potential beneficial effect in congestive heart failure. The enriched localization of CGRP in trigeminal sensory ganglia may indicate a role in the neurogenic inflammation associated with migraine. Thus, CGRP antagonists may represent a novel therapeutic approach to the treatment of migraine. In addition, CGRP and amylin (homologous pancreatic peptide) reduce the tissue--glucose response to insulin. It has been suggested that a CGRP antagonist may therefore improve insulin sensitivity in non-insulin-dependent diabetes, NIDDM. This brief review provides a preliminary exploration of the potential therapeutic opportunities surrounding CGRP and CGRP antagonists. Future advances are dependent on a better understanding of the structure and function of CGRP receptor(s) and the concomitant identification of selective and potent agonists and antagonists useful for addressing therapeutic hypotheses.

Preditive clinical factors for epileptic seizures after ischemic stroke. Clinical features of 35 patients with ischemic stroke who developed epilepsy (Group 1) were compared with those of 35 patients with ischemic stroke without epilepsy (Group 2). The age of the patients did not differ between the groups. There were more men than women and more white than other races in both groups. Diabetes melitus, hypertension, transient ischemic attack, previous stroke, migraine, Chagas disease, cerebral embolism of cardiac origin and use of oral contraceptive did not differ between the groups. Smokers and alcohol users were more frequent in Group 1 (p < 0.05). Most patients of Group 1 presented with hemiparesis; none presented cerebellar or brainstem involvement. Perhaps strokes in smokers have some different aspects, that let them more epileptogenic than in non smokers.

Although headache is among the most common pain complaints seen by physicians, the measurement of health-related quality of life (HRQoL) in headache patients is in its earliest stages. Two types of questionnaire have been used to measure HRQoL in headache sufferers: general and disease-specific instruments. General quality-of-life (QoL) instruments use scales to assess QoL with respect to a number of activities within physical, social, psychological, and behavioral life domains. Disease-specific instruments reflect particular limitations or restrictions associated with specific disease states. These instruments are designed to be most sensitive in determining the effects of treatment or the longitudinal course of disease. Data from the Medical Outcomes Study Short Form (SF)-20 and SF-36 generic QoL instruments demonstrated that chronic headache disorders were associated with significant limitations in all eight health domains of patient wellbeing and functioning. The SF-20 outcomes profiles for each of the common benign headache disorders (migraine, tension-type headache, mixed headache, and cluster headache) appear to be unique for the specific headache diagnosis. The SF-20 and SF-36 were also used to compare headache disorders with other chronic illnesses. Chronic headache disorders, including migraine, were found to cause significantly more impairment of function than diabetes, hypertension, osteoarthritis, and low back pain. Preliminary studies of QoL during pharmacologic therapy have suggested that disease specific instruments may be more sensitive than generic instruments for evaluating the longitudinal impact of treatment. Generic QoL instruments, such as the SF-20 or SF-36, may be more useful to define populations being studied than to measure changes in the population over time. The publication of headache-specific QoL instruments, which have been widely used in clinical trials and have been validated, is awaited. Until such time, the SF-36 will remain the standard measure of QoL in headache.

The aims of this ancillary study to the Italian Longitudinal Study of Aging were: (1) to provide reliable prevalence data on headache in an elderly population, (2) to classify the subtypes of headache according to International Headache Society criteria, and (3) to identify possible risk factors and associated pathologies in the elderly. A total of 312 subjects were examined, 148 women and 164 men, with a mean age of 73 years (SD 5.5). For 236 subjects (75.7%), 141 men (85.9%) and 95 women (64.2%), headache had never been a problem; 57 subjects (18.3%), 21 men (12.8%) and 36 women (24.3%), reported troublesome headache only in the past. Nineteen subjects (6%), 6 men (3.6%) and 13 women (8.8%), reported current headache: in this group tension-type headache was the most prevalent, accounting for 2.6%; secondary headaches ranked second, accounting for 2.2%; and only 1% had current migraine. Our data indicate female sex and younger age as risk factors for headache, and associate migraine and secondary headaches with hypertension, tension-type headaches and secondary headaches with diabetes, and tension-type headaches with myocardial ischemia.
