Cerebral ischemia (cerebrovascular insufficiency) occurs when blood flow to the brain decreases, depriving brain cells of oxygen and nutrients. Symptoms often include headaches, dizziness, tinnitus, memory loss, and insomnia. Causes can range from atherosclerosis and cervical spondylosis to low blood pressure and blood clotting disorders. Doctor Nguyen Anh Duy Tung from the Nutrihome Nutrition Center explains that in addition to medical treatment, a diet rich in vitamins, minerals, and antioxidants can help improve blood circulation and protect brain cells from damage.

Oranges and grapefruits are packed with vitamin C, which strengthens the immune system, supports healthy blood vessels, and improves blood flow. Vitamin C also promotes iron absorption from food, helping prevent anemia, a condition that can exacerbate cerebral ischemia.

Bananas are rich in potassium and magnesium, which help regulate blood pressure, support a steady heart rate, and reduce the risk of cerebral vasospasm. The vitamin B6 in bananas contributes to neurotransmitter production, improving mood and memory.

Blueberries contain anthocyanins, potent antioxidants that protect brain cells from free radicals and improve cognitive function. Regularly consuming blueberries supports increased blood flow to the brain, reducing the risk of memory decline in older adults.

Avocados are rich in monounsaturated fats, vitamin E, and folate, which can maintain blood vessel elasticity and protect nerve cells. Folate plays a crucial role in red blood cell production, thus improving oxygen supply to the brain.

Apples contain the antioxidant quercetin, which has anti-inflammatory properties and supports better blood circulation. Apples are also rich in soluble fiber, which helps control cholesterol and reduces the risk of atherosclerosis, a common cause of cerebral ischemia.

Doctor Duy Tung advises those experiencing persistent cerebral ischemia, frequent headaches, dizziness, tinnitus, or memory loss to consult a neurologist for diagnosis, determination of the cause, and timely treatment. He cautions against self-medicating with blood circulation enhancers or using supplements from unknown sources, as these may interact with prescribed medications, affect blood pressure, or worsen underlying conditions. Depending on the case, doctors may prescribe medication to increase cerebral circulation, physical therapy, or treatment of underlying causes such as managing cholesterol, blood pressure, or cervical spondylosis.

Individuals with cerebral ischemia should consume plenty of green vegetables, fatty fish, and nuts to provide adequate nutrients for the brain. Limiting foods high in sugar, salt, saturated fat, and alcoholic beverages is also recommended. Maintaining a healthy weight, engaging in moderate exercise, getting enough sleep, and managing blood pressure and cholesterol can prevent the condition from worsening. Incorporating natural extracts like those from blueberries and ginkgo biloba can contribute to improved blood flow to the brain.
