Cerebral Perfusion Pressure in Intracerebral Hemorrhage

Intracerebral_Hemorrhage

Intracerebral hemorrhage accounts for approximately only 12% of all strokes, but it is one of the most disabling forms. The high rate of morbidity and mortality associated with intracerebral hemorrhage has prompted investigations for new medical and surgical therapies. This syndrome occurs when a blood vessel within the brain ruptures, allowing blood to leak inside the…

Salt Intake and Blood Pressure in Cerebral Small Vessel Disease

Dietary_Salt_Intake

Excess salt consumption is associated with increased risk of stroke and cardiovascular complications, such as cerebral small vessel disease. Several studies have established a causal relation between daily dietary salt intake and high blood pressure, which has a prominent role in promoting cardiovascular diseases. However, high sodium might weigh in on the development of cerebral…

White Matter Lesions in Stroke Patients

Stroke Lesions

Aging is associated with the appearance of increased white spots visualized on brain MRI scans. The presence of these anomalies, called white matter hyperintensities, characterizes elderly subjects as well as ischemic stroke patients, regardless of their age. White matter hyperintensities are thought to be caused by small vessel infarcts (restriction in blood flow) in the…

Predicting Outcomes in Acute Ischemic Stroke

Imaging Techniques

Stroke is the second leading cause of death worldwide according to the World Health Organization. A stroke involves the loss of brain function due to a disturbance in blood supply to the brain. It can be caused by either a blood clot that blocks or plugs a blood vessel in the brain (ischemic stroke) or a blood vessel that breaks and bleeds…

Lower Childhood IQ May Be a Predictor of Brain Lesions Associated with Stroke and Dementia

low_IQ_and_dementia

Late-life cognitive decline due to dementia and stroke may have its origins in childhood intelligence, according to a recent study. While previous studies have shown an association between educational level and late-life cognitive decline and dementia, researchers at the University of Edinburgh suggests that early childhood IQ might also be a predictor of late-life organic brain…

Ischemic Stroke Recovery and the Role of Cerebral GABA Activity

Stroke

Stroke is the leading cause of disability in the world. It is the second leading cause of dementia, and the third most common cause of death. Stroke has a world incidence of 9.0 million and world prevalence of 30.7 million. There are two major kinds of stroke; hemorrhagic stroke and ischemic stroke. Ischemic stroke is…
