A transient ischemic attack (TIA), commonly known as a mini-stroke, is a minor stroke whose noticeable symptoms usually end in less than an hour. TIA causes the same symptoms associated with strokes, such as weakness or numbness on one side of the body, sudden dimming or loss of vision, difficulty speaking or understanding language, slurred speech, or confusion.
Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. Arteries supplying oxygen and nutrients to the brain are often damaged or deformed in these disorders. The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. Hypertension is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis. Atherosclerosis narrows blood vessels in the brain, resulting in decreased cerebral perfusion. Other risk factors that contribute to stroke include smoking and diabetes. Narrowed cerebral arteries can lead to ischemic stroke, but continually elevated blood pressure can also cause tearing of vessels, leading to a hemorrhagic stroke.
Stroke is a medical condition in which poor blood flow to the brain causes cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. Both cause parts of the brain to stop functioning properly.
CADASIL or CADASIL syndrome, involving cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, is the most common form of hereditary stroke disorder, and is thought to be caused by mutations of the Notch 3 gene on chromosome 19. The disease belongs to a family of disorders called the leukodystrophies. The most common clinical manifestations are migraine headaches and transient ischemic attacks or strokes, which usually occur between 40 and 50 years of age, although MRI is able to detect signs of the disease years prior to clinical manifestation of disease.
A thunderclap headache is a headache that is severe and has a sudden onset. It is defined as a severe headache that takes seconds to minutes to reach maximum intensity. Although approximately 75% are attributed to "primary" headaches—headache disorder, non-specific headache, idiopathic thunderclap headache, or uncertain headache disorder—the remainder are secondary to other causes, which can include some extremely dangerous acute conditions, as well as infections and other conditions. Usually, further investigations are performed to identify the underlying cause.
Carotid artery stenosis is a narrowing or constriction of any part of the carotid arteries, usually caused by atherosclerosis.
Desmoteplase is a novel, highly fibrin-specific "clot-busting" (thrombolytic) drug in development that reached phase III clinical trials. The Danish pharmaceutical company, Lundbeck, owns the worldwide rights to Desmoteplase. In 2009, two large trials were started to test it as a safe and effective treatment for patients with acute ischaemic stroke. After disappointing results in DIAS-3, DIAS-4 was terminated, and in December 2014 Lundbeck announced that they would stop the development of desmoteplase.
Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain, into its ventricles, or into both. An ICH is a type of bleeding within the skull and one kind of stroke. Symptoms can vary dramatically depending on the severity, acuity, and location (anatomically) but can include headache, one-sided weakness, numbness, tingling, or paralysis, speech problems, vision or hearing problems, memory loss, attention problems, coordination problems, balance problems, dizziness or lightheadedness or vertigo, nausea/vomiting, seizures, decreased level of consciousness or total loss of consciousness, neck stiffness, and fever.
Transient global amnesia (TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories. A person in a state of TGA exhibits no other signs of impaired cognitive functioning but recalls only the last few moments of consciousness, as well as possibly a few deeply encoded facts of the individual's past, such as their childhood, family, or home perhaps.
The ABCD2 score is a clinical prediction rule used to determine the risk for stroke in the days following a transient ischemic attack (TIA, a condition in which temporary brain dysfunction results from oxygen shortage in the brain). Its usefulness was questioned in a 2015 review as it was not found to separate those who are at low from those who are at high risk of future problems. A high score correctly predicted 87% of the people who did have a stroke in the following 7 days but also many people who did not have problems.
Steven Laureys is a Belgian neurologist. He is principally known as a clinician and researcher in the field of neurology of consciousness.
Reversible cerebral vasoconstriction syndrome is a disease characterized by a weeks-long course of thunderclap headaches, sometimes focal neurologic signs, and occasionally seizures. Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. In some cases, it may be associated with childbirth, vasoactive or illicit drug use, or complications of pregnancy. If it occurs after delivery it may be referred to as postpartum cerebral angiopathy.
Sarah Joanna Tabrizi FMedSci is a British neurologist and neuroscientist in the field of neurodegeneration, particularly Huntington's disease. She is a Professor and Joint Head of the Department of Neurodegenerative Diseases at the UCL Institute of Neurology; the founder and Director of the UCL Huntington's Disease Centre; a Principal Investigator at the UK Dementia Research Institute at UCL; and an Honorary Consultant Neurologist at the National Hospital for Neurology and Neurosurgery, Queen Square, London, where she established the Multidisciplinary Huntington's Disease Clinic. The UCL Huntington’s Disease Centre was officially opened on 1 March 2017 by UCL President and Provost Professor Michael Arthur.
A mobile stroke unit(MSU) is an ambulance that furnishes services to diagnose, evaluate, and/or treat symptoms of an acute stroke. It may contain, in addition to the normal ambulance equipment, a device for brain imaging (computerized tomography), a point-of-care laboratory and telemedical interaction between ambulance and hospital (videoconferencing, exchange of videos of patient examination and CT scans). Thus, this specialized ambulance includes all the tools necessary for hyperacute assessment and treatment of stroke patients and diagnosis-based triage directly at the emergency site.
Joanna Marguerite Wardlaw is a Scottish physician, radiologist, and academic specialising in neuroradiology and pathophysiology. Wardlaw worked as a junior doctor before specialising as a radiologist. She continues to practice medicine as an Honorary Consultant Neuroradiologist with NHS Lothian. She has spent her entire academic career at the University of Edinburgh.
Embolic stroke of undetermined source (ESUS) is an embolic stroke, a type of ischemic stroke, with an unknown origin, defined as a non-lacunar brain infarct without proximal arterial stenosis or cardioembolic sources. As such, it forms a subset of cryptogenic stroke, which is part of the TOAST-classification. The following diagnostic criteria define an ESUS:

She is the current Chief Executive of The Encephalitis Society, a non-profit organisation which provides support and resources for those affected by the neurological disease of Encephalitis, and collaborates with various organisations on research into the disease.
The Boston criteria version 2.0 is a set of guidelines designed to diagnose cerebral amyloid angiopathy (CAA), a disease that affects small blood vessels in the brain, particularly those in the cortex and leptomeninges. Although the gold standard for diagnosis is histopathological examination, the Boston criteria provide clinicians with a probabilistic approach for diagnosis largely based on imaging characteristics.
