Summary
This review found that Ginkgo biloba extracts show positive results for treating cerebral insufficiency, similar to registered medications. However, methodological limitations in many studies necessitate further research for definitive efficacy assessment.
Area of Science:
- Pharmacology
- Clinical Trials
- Neuroscience
Background:
- Cerebral insufficiency is a condition affecting cognitive function.
- Ginkgo biloba extracts are widely used for cognitive enhancement.
- Evidence for efficacy requires rigorous scientific evaluation.
Purpose of the Study:
- To critically review controlled human trials on Ginkgo biloba extract efficacy for cerebral insufficiency.
- To assess the methodological quality of existing trials.
- To compare the evidence quality with co-dergocrine, a registered treatment.
Main Methods:
- A critical review of 40 controlled trials was performed.
- Methodological quality was assessed using predefined criteria.
- Trial outcomes were interpreted in relation to quality and compared to co-dergocrine trials.
Main Results:
- Eight out of 40 trials were well-performed, but many had methodological shortcomings.
- Most trials reported positive results, often with 120 mg/day of Ginkgo biloba for 4-6 weeks.
- The quality of evidence for Ginkgo biloba was comparable to co-dergocrine in the best trials.
Conclusions:
- Ginkgo biloba extracts demonstrate positive reported outcomes for cerebral insufficiency.
- The clinical evidence is comparable to existing registered treatments.
- Further high-quality studies are required to definitively assess efficacy and mitigate potential biases.

01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
