Ginkgo contains compounds that have antioxidant and anti-inflammatory properties, which are believed to help improve blood circulation and protect brain cells from damage. Some studies have suggested that ginkgo may have a modest positive effect on cognitive function and memory in older adults with mild cognitive impairment or dementia. However, the results have been mixed, and the overall evidence is not strong enough to draw definitive conclusions. It's important to note that individual responses to ginkgo can vary, and some people may experience improvements in cognitive function while others may not notice any difference. Additionally, Ginkgo can interact with certain medications and may have side effects such as headaches, dizziness, and digestive issues. If you're experiencing persistent brain fog or cognitive difficulties, it's recommended to consult with a healthcare professional. They can help determine the underlying causes and provide appropriate guidance and treatment options tailored to your specific situation.
