A parietal lobe stroke is a type of stroke that occurs in the back part of the brain known as the parietal lobe. The type and severity of parietal stroke symptoms are based largely on the location and size of the injury, but can include impairment of speech, thought, coordination, and movement.

A watershed infarct is a stroke caused by a drop in circulating pressure and or volume that results in critical ischaemia or infarction between territories. Classically between MCA and ACA or MCA and PCA. The actual blood stream blockage/restriction site can be located far away from the infarct.

Classically between MCA and ACA or MCA and PCA. The actual blood stream blockage/restriction site can be located far away from the infarct. Location of stroke: A lacunar infarct is a small stroke, usually deep in the brain matter. Periventricular means near the ventricles also deep in the brain. A stroke in t Watershed infarct Hypoperfusion → Watershed Infarct .

Parieto-occipital watershed infarct

These lesions constitute approximately 10% of all brain in-farcts and are well described in the literature. Their pathophysiology has not yet been fully elucidated, but a commonly accepted hypothesis A temporal lobe stroke can produce trouble with communication, which is called aphasia.Language function is primarily located on the dominant side of the brain, which is the left side of the brain for right-handed people, and the right side of the brain for many left-handed people. Watershed infarct Hypoperfusion → Watershed Infarct . Due to cerebral venous thrombosis: - increased venous pressure, increased capillary pressure This configuration is typical for deep borderzone or watershed infarction; in this case, the anterior and posterior middle cerebral artery (MCA) watershed areas.

A case report involving a visual field defect secondary to a bilateral parieto-occipital cortex infarct is discussed.

The external or cortical border zones are located at the junctions of the anterior, middle, and posterior cerebral artery territories. Infarcts in the anterior external border zones and paramedian white matter are found at the junction of the territories supplied by the anterior and middle cerebral arteries, and those in the parieto-occipital areas (posterior external border zones) are found

Acta Neurochir Suppl 7: 51 Vascular watershed or border-zone infarctions occur at the most distal areas between arterial territories (see the image below). They are believed to be secondary to embolic phenomenon or due to Right parieto-occipital lacunar infarction with agitation, hallucinations, and delusions Cerebrovascular accidents are a leading cause of serious long-term disability. Accurate diagnosis of a cerebrovascular accident is crucial to prevent morbidity, mortality and functional loss.

The cortical infarcts were numerous in the parieto-occipital region. There were no cortical infarcts on the convexity of the occipital poles supplied by the posterior

We did not observe any cortical microinfarcts in or outside watershed areas in the sixth case selected from the AD group, in which cortical infarct was not found by the standard procedure. Border zone or watershed infarcts are ischemic lesions that occur in characteristic locations at the junction between two main arterial ter-ritories.

We did not observe any cortical microinfarcts in or outside watershed areas in the sixth case selected from the AD group, in which cortical infarct was not found by the standard Abstract. Neuropsychological deficits after occipital infarction are most often described in case studies and only a small sample of studies has attempted to exactly correlate the anatomical localization of lesions with associated neuropsychological symptoms. The present study investigated a large number of patients (N = 128) in order to provide an overview of neurological and neuropsychological deficits after occipital, occipito-temporal and occipito-parietal infarction. Cerebrovascular accidents are a leading cause of serious long-term disability. Accurate diagnosis of a cerebrovascular accident is crucial to prevent morbidity, mortality and functional loss. A case report involving a visual field defect secondary to a bilateral parieto-occipital cortex infarct is discussed.
