Stroke

Apraxia is a motor disorder caused by damage to the brain (specifically the posterior parietal cortex), in which the individual has difficulty with the motor planning to perform tasks or movements when asked, provided that the request or command is understood and he/she is willing to perform the task.

Receptive aphasia, also known as Wernicke's aphasia, fluent aphasia, or sensory aphasia, is a type of aphasia in which an individual is unable to understand language in its written or spoken form.

Anosognosia (/æˌnɒsɒɡˈnoʊziə/, /æˌnɒsɒɡˈnoʊʒə/; from Ancient Greek ἀ- a-, "without", νόσος nosos, "disease" and γνῶσις gnōsis, "knowledge") is a deficit of self-awareness, a condition in which a person who suffers some disability seems unaware of the existence of his or her disability.

Moyamoya disease is a disease in which certain arteries in the brain are constricted.

Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space — the area between the arachnoid membrane and the pia mater surrounding the brain.

A transient ischemic attack (TIA) is a transient episode of neurologic dysfunction caused by ischemia (loss of blood flow) – either focal brain, spinal cord, or retinal – without acute infarction (tissue death).

Intracranial hemorrhage (ICH), also known as intracranial bleed is bleeding within the skull.

Vertebrobasilar insufficiency (VBI) or vertebral-basilar ischemia, also called beauty parlour syndrome (BPS), is a temporary set of symptoms due to decreased blood flow (ischemia) in the posterior circulation of the brain.

Expressive aphasia (non-fluent aphasia) is characterized by the loss of the ability to produce language (spoken or written).

Cerebral venous sinus thrombosis (CVST) is the presence of acute thrombosis (a blood clot) in the dural venous sinuses, which drain blood from the brain.

Claude's syndrome is a form of brainstem stroke syndrome characterized by the presence of an ipsilateral oculomotor nerve palsy, contralateral hemiparesis, contralateral ataxia, and contralateral hemiplegia of the lower face, tongue, and shoulder.

A Total Anterior Circulation Infarct (TACI) is a type of cerebral infarction affecting the entire anterior circulation supplying one side of the brain.

Anomic aphasia (also known as dysnomia, nominal aphasia, and amnesic aphasia) is a type of aphasia where an individual has consistent inability to produce words for things that they want to talk about (particularly nouns and verbs).

Cortical deafness is a rare form of sensorineural hearing loss caused by damage to the primary auditory cortex.

Ideomotor Apraxia, often IMA, is a neurological disorder characterized by the inability to correctly imitate hand gestures and voluntarily mime tool use, e.

A silent stroke is a stroke that does not have any outward symptoms associated with stroke, and the patient is typically unaware they have suffered a stroke.

A lateral pontine syndrome is a lesion which is similar to the lateral medullary syndrome, but because it occurs in the pons, it also involves the cranial nerve nuclei of the pons.

Medial inferior pontine syndrome is a condition associated with a contralateral hemiplegia.

Conduction aphasia, also called associative aphasia, is a relatively rare form of aphasia.

Amaurosis fugax (Latin fugax meaning fleeting, Greek amaurosis meaning darkening, dark, or obscure) is a painless transient monocular or binocular visual loss (i.e., loss of vision in one or both eyes that is not permanent).

Benedikt syndrome, also called Benedikt's syndrome or paramedian midbrain syndrome, is a rare type of posterior circulation stroke of the brain, with a range of neurological symptoms affecting the midbrain, cerebellum and other related structures.

Millard–Gubler syndrome is a lesion of the pons.

Foville's syndrome is caused by the blockage of the perforating branches of the basilar artery in the region of the brainstem known as the pons.

Intraparenchymal hemorrhage (IPH) is one form of intracerebral bleeding in which there is bleeding within brain parenchyma.

A watershed stroke or watershed infarct is defined as an ischemia that is localized to the border zones between the territories of two major arteries in the brain.

Dipyridamole (trademarked as Persantine) is a medication that inhibits blood clot formation when given chronically and causes blood vessel dilation when given at high doses over a short time.

Intracerebral hemorrhage (ICH), also known as cerebral bleed, is a type of intracranial bleed that occurs within the brain tissue or ventricles.

Anterior cerebral artery syndrome is a condition whereby the blood supply from the anterior cerebral artery (ACA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the medial aspects of the frontal and parietal lobes, basal ganglia, anterior fornix and anterior corpus callosum.

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, caudate and putamen.

Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery (PCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the upper brainstem and midbrain.

A brainstem stroke syndrome is a condition involving a stroke of the brainstem.

Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery.

Brain ischemia (aka cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand.

Lacunar stroke or lacunar infarct (LACI) is a type of stroke that results from occlusion of one of the penetrating arteries that provides blood to the brain's deep structures.

Lateral medullary syndrome (also called Wallenberg syndrome and posterior inferior cerebellar artery syndrome) is a disorder in which the patient has a constellation of neurologic symptoms due to injury to the lateral part of the medulla in the brain, resulting in tissue ischemia and necrosis.
