A retrospective cohort study was carried out of new referrals to transient ischaemic attack (TIA) clinics in Glasgow. The aims of the study were to describe the profile of referrals and to assess the odds ratios for TIA, minor stroke or amaurosis fugax of both cardiovascular risk factors and clinical features. In total, data were collected for 813 new referrals in a period of six months. Thirteen point eight percent of referrals were from other Health Boards. The overall referral rate among residents of Greater Glasgow NHS Board was 165.6 per 100,000 per year. About 20% of referrals were made by clinicians in secondary care. The specialties from which referrals were most commonly made were accident and emergency, general medicine, ophthalmology and geriatric assessment. The most common risk factors in patients referred were hypertension (52.9%), smoking (31.7%), ischaemic heart disease (22.7%) and former smokers (22.4%). The most common clinical features were hemiparesis (13.3%), weakness of an upper limb (8.7%), vertigo (7.9%) and dysphasia (7.3%). In 48.7% of cases, a non-cerebrovascular diagnosis was made. Separate multivariate models were established for risk factors and clinical features. In the model for risk factors, five factors were significant for risk of TIA, stroke or amaurosis fugax. These were hyperlipidaemia, age over 64 years, hypertension, smoking and ex-smoking. In the model for clinical features, five factors were also significant. These were visual field defect, speech defact, facial weakness and hemiparesis.

Open surgery for thoracic aortic disease is associated with significant morbidity and the reported rates for paraplegia and stroke are 3%-19% and 6%-11%, respectively. Spinal cord ischemia and stroke have also been reported following endoluminal repair. This study reviews the incidence of paraplegia and stroke in a series of 186 patients treated with thoracic stent grafts. From July 1997 to September 2006, 186 patients (125 men) underwent endoluminal repair of thoracic aortic pathology. Mean age was 71 years (range, 17-90 years). One hundred twenty-eight patients were treated electively and 58 patients had urgent procedures. Anesthesia was epidural in 131, general in 50, and local in 5 patients. Seven patients developed paraplegia (3.8%; two urgent and five elective). All occurred in-hospital apart from one associated with severe hypotension after a myocardial infarction at 3 weeks. Four of these recovered with cerebrospinal fluid (CSF) drainage. One patient with paraplegia died and two had permanent neurological deficit. The rate of permanent paraplegia and death was 1.6%. There were seven strokes (3.8%; four urgent and three elective). Three patients made a complete recovery, one had permanent expressive dysphasia, and three died. The rate of permanent stroke and death was 2.1%. Endoluminal treatment of thoracic aortic disease is an attractive alternative to open surgery; however, there is still a risk of paraplegia and stroke. Permanent neurological deficits and death occurred in 3.7% of the patients in this series. We conclude that prompt recognition of paraplegia and immediate insertion of a CSF drain can be an effective way of recovering spinal cord function and improving the prognosis.

In recent years, post-stroke depression (PSD) has attracted a worldwide interest. This review addresses the major research issues of PSD. PSD is the most frequent psychic complication among stroke survivors. Depression has a significant impact on post-stroke recovery and mortality. The diagnosis of PSD is based on the structured mental state examination and DSM-IV criteria as well as on the scores of the clinical symptoms scale (the Hamilton Depression Rating Scale) and self-rated inventories. PSD is multifactorial in origin and develops under the influence of biopsychosocial factors. The anatomical correlates of PSD change over time. In acute stage and 3-6 months after stroke, depression is associated with left-hemisphere lesion severity and proximity of the lesion to the frontal pole and related to the dysfunction of (cortico-) striato-pallido-thalamic-cortical projections. In post-stroke period (1-2 years) depression is significantly associated with right-hemisphere lesion severity and proximity of the lesion to the occipital pole. The most relevant psychosocial risk factors for PSD are described as follows: past history of depression and other mental disorders, dysphasia, functional impairment, living alone and post-stroke social isolation. Selective serotonin reuptake inhibitors (citalopram and fluoxetine) may be effective in the treatment of PSD.

This paper describes the case of a 32-year-old man presenting with dense right hemiplegia and global aphasia caused by an acute left middle cerebral artery infarct that underwent successful endovascular therapy after being determined ineligible for intravenous tissue plasminogen activator. Clot transversion and balloon disruption followed by intra-arterial Alteplase resulted in successful re-canalization of his middle cerebral artery at 7 h 30 min. At 3 months post stroke, the patient had moderately severe expressive dysphasia but was mobilizing independently with normal right upper and lower limb strength. In conclusion, the 3 month outcome suggests that the therapeutic time window for endovascular therapy might exceed 6 h post stroke.

Headache with neurologic deficits and cerebrospinal fluid lymphocytosis is a benign condition with a transient ischemic attack-like presentation. We present a case of a 22-year-old man with episodes of right-sided weakness, global dysphasia, and right-sided homonymous hemianopsia associated with frequent vomiting. Systemic thrombolytic therapy was considered. A subsequent magnetic resonance image with diffusion-weighted images revealed normal findings. A diagnosis of headache with neurologic deficits and cerebrospinal fluid lymphocytosis was made based mainly on clinical symptoms and cerebrospinal fluid analysis. With the current pressure on "door-to-needle" time for thrombolysis, it is important to keep an open eye to stroke mimics and exclude them if possible. We, therefore, strongly advise considering noninvasive magnetic resonance diffusion-weighted imaging in patients with unusual presentations (e.g., the vomiting in our patient) before thrombolysis.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is caused by mutations in the Notch3 gene on chromosome 19. The condition manifests itself clinically typically in the third to fifth decade with migraine and recurrent episodes of stroke or transient ischaemic attacks. We report the case of an 11-year-old male with CADASIL resulting in stroke with right hemiparesis and dysphasia. Acute magnetic resonance imaging suggested infarction in the left hemisphere; magnetic resonance angiography revealed calibre variation of the intracerebral arteries. The patient suffered from common migraine with five to six attacks per month for 3 years 6 months before the stroke. Attacks occurred early in the morning with severe one-sided headache, photophobia, nausea, and vomiting. Antimigraine medications had no effect. The family history revealed more cases of CADASIL, with an autosomal dominant pattern. The diagnosis of CADASIL was confirmed by the finding of the known mutation of the Notch3 gene running in the family. With treatment in a neurorehabilitation centre the patient recovered most of his functions with only discrete fine-motor and cognitive sequelae. Our case report highlights the need for paediatricians to consider CADASIL in childhood stroke as well as in migraine patients.

A 48-year-old female presented to an emergency room with symptoms of episodic hemianopsia, dysphasia, and facial numbness. She had no obvious risk factors for cerebral vascular disease but was admitted into the hospital with a diagnosis of transient ischemic attack (TIA). A neurologist reviewed her history and discovered the additional history of bilateral head pressure accompanying her symptoms. The additional diagnosis of complex migraine with aura was added to the differential diagnosis. Migraine with aura is associated with many neurologic symptoms and can mimic stroke and TIA. Migraine-induced stroke is also described in the literature. The complex presentation of some episodes of migraine makes attention to a detailed history paramount for assessing the patient for diagnosis and for risk selection. Recent studies have demonstrated an association between migraine headaches and cardiovascular morbidity and mortality. The attributable mortality risk for migraine-induced stroke is very low.

A 26-year-old man admitted with dysphasia and bilateral headache for three days. He had no known risk factors for stroke. Transthoracic two-dimensional echocardiography showed prominent trabeculations, with deep intertrabecular recesses in apex of the right ventricle. The multi-detector-row spiral cerebral computerized tomography revealed a little infarction in bilateral temporal and frontal lobe. The main mechanisms of neurovascular complications in NVM may be related to development of thrombi in the intertrabecular space. Extensively trabeculated ventricle, depressed systolic function, and/or the development of atrial fibrillation are the causes for thrombus formation7. Embolic stroke has been only rarely described in association with NVM9. However, whether NVM is a risk factor for stroke is controversially discussed. Prevention of embolic complications is an important management issue, and several authors have recommended long-term prophylactic anticoagulation for patients in NVM with atrial fibrillation and severe systolic dysfunction. The field of neurovascular complications, and specially cerebral infarction, in NVM of right ventricular remains not yet fully understood.

Migraine is the cause of 3-25% of strokes in young adults. Each year we can expect 9-10 cases of migraine-related stroke in Iceland. The most common symptom is hemianopia but other common symptoms include hemiparesis, hemianesthesia, dysphasia and various brain stem symptoms. The stroke must occur during a typical migraine attack and other causes have to be excluded. Here we describe two cases of migraine-related stroke.

X-linked hereditary motor sensory neuropathy type 1 (CMTX 1) is caused by mutation in the GJB1 gene that codes for the connexin 32 protein. Central nervous system involvement with or without white matter changes on magnetic resonance imaging (MRI) has rarely been reported in this condition. We report the case of a 7-year-old, previously well male who presented with a stroke-like episode that manifested as left hemiparesis and dysphasia. An initial brain MRI showed white matter signal changes affecting the corpus callosum and periventricular areas with a posterior predominance. Our patient made a complete clinical recovery in 36 hours. Clinical examination at this stage showed no evidence of a peripheral neuropathy. A repeat brain MRI 6 weeks later showed almost complete resolution of the changes seen initially. Subsequent investigations showed a Val177Ala mutation in the GJB1 gene. This mutation has so far not been described in the Caucasian population and has been only described once before. Electrophysiological studies showed a mixed demyelinating and axonal sensorimotor neuropathy in keeping with CMTX 1. Five months after the initial presentation our patient developed clinical evidence of a peripheral neuropathy in the form of absent ankle reflexes, weak dorsiflexors, and evertors of both feet.
