What are the four common stroke syndromes?
There is a list of “classical” stroke syndromes arranged by arterial terriotry, which one needs to commit to memory. This list includes dominant and non-dominant MCA infarction, medial and lateral medullary syndromes, anterior and posterior cerebral artery syndromes and the basilar artery syndrome.
What is MCA syndrome?
Middle cerebral artery syndrome is a condition whereby the blood supply from the middle cerebral artery (MCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the lateral aspects of frontal, temporal and parietal lobes, the corona radiata, globus pallidus.
What are the different stroke syndromes?
There are various subsets of brain stem syndromes, for example, dorsolateral medullary syndrome of Wallenberg, medial medullar syndrome of ‘Dejerine’, anterior inferior cerebellar artery syndrome (AICAS), superior cerebellar artery syndrome, the ‘locked-in’ syndrome and the ‘top-of-the-basilar’ syndrome.
What are the symptoms of MCA stroke?
Middle Cerebral Artery (MCA) Stroke
- Deficits in movement and sensation (contralateral hemiplegia and hemianesthesia);
- Difficulty swallowing (dysphagia);
- Impaired speech ability (dysarthria, aphasia);
- Impaired vision and partial blindness (hemianopia);
- Headaches; and.
- Hemineglect.
What is the most common stroke syndrome?
Ischemic stroke It can occur in the carotid artery of the neck as well as other arteries. This is the most common type of stroke. It happens when the brain’s blood vessels become narrowed or blocked, causing severely reduced blood flow (ischemia).
What is ICA occlusion?
A complete occlusion of the internal carotid artery (ICA) is an important cause of cerebrovascular disease. A never‐symptomatic ICA occlusion has a relatively benign course, whereas symptomatic occlusion increases future risk of strokes.
What is a mild stroke?
A mild stroke is known as a transient ischemic attack, or TIA. When someone is having a mild stroke, their physical symptoms usually disappear within a few minutes. However, even in the instance of a mild stroke, the brain sustains some damage. Signs of a mild stroke include: Blurred vision.
What are the two main types of stroke?
Types of Stroke
- Ischemic stroke.
- Hemorrhagic stroke.
- Transient ischemic attack (a warning or “mini-stroke”).
What is right ICA occlusion?
Where does subcortical stroke occur in the brain?
Subcortical strokes affect the small vessels deep in the brain, and typically present with purely motor hemiparesis affecting the face, arm, and leg. Nearly 30% of all ischemic strokes are subcortical in nature, and includes lacunar infarcts which have the best prognosis.
Is there a second edition of subcortical stroke?
This is the second edition of Subcortical Stroke which testifies to the contribution this book has made in attempting to clarify this complex issue. It is excellent. Subcortical stroke is the subject of much confusion—some regard this term as synonymous with lacunar stroke, which it most definitely is not.
What kind of strokes affect the cerebral cortex?
Strokes affecting the cerebral cortex (i.e. cortical strokes) classically present with deficits such as neglect, aphasia, and hemianopia. Subcortical strokes affect the small vessels deep in the brain, and typically present with purely motor hemiparesis affecting the face, arm, and leg.
Can a stroke be confirmed by a MRI?
About 80% of clinical subcortical clinical strokes will be confirmed by conventional MRI. However about 10% of patients with classical lacunar syndromes confirmed on imaging, had non‐lacunar mechanisms for infarction, e.g. large vessel disease.
