Ischaemic stroke patients are less likely to deteriorate mentally if they take ginkgo biloba extract in addition to low-dose aspirin in the acute phase, a new study suggests.“Cognitive decline after stroke can result in vascular cognitive impairment and Alzheimer’s disease,” the study authors wrote.Importantly then, this randomised controlled trial showed stroke patients who took ginkgo as well as aspirin had better memory function, executive functions, neurological function and daily life in the six months after experiencing their stroke than those patients who took aspirin alone.The Chinese study also showed that taking ginkgo was not associated with an increased incidence of adverse events.The results of the study, published in the journal, Stroke and Vascular Neurology support the long-held hypothesis that ginkgo protects against neuronal death caused by ischaemia, which had been demonstrated in animal stroke models.It has been suggested that the possible mechanism of ginkgo’s effectiveness may include anti-apoptosis and increasing cerebral blood flow. In the study, researchers randomised over 340 patients, from five hospitals who had had an ischaemic stroke in the previous seven days to receive either 450mg of ginkgo biloba extract with 100mg aspirin daily or only the 100mg of aspirin daily.Both groups were treated for six months and were various intervals over that period. From the very early assessments (at 12 days) and through until 180 days, the difference in the assessments of cognitive and executive function was statistically significant. Similarly neurological and global function was significantly better in the group that took ginkgo.“These data suggest that [ginkgo biloba extract] is effective and could be recommended in the treatment of acute ischaemic stroke,” the study authors concluded.Ref: Li S, et al.
