Does wearing multiple layers of face masks cause reduced blood flow to the brain?

Recently, I've been experiencing symptoms like headaches, dizziness, and lightheadedness, similar to those of cerebral ischemia. Could this be due to wearing too many layers of face masks, causing cerebral ischemia? (T. Dao, 35 years old, Ho Chi Minh City).

Dr. Le Viet Thang , a physician in the Neurosurgery Department of the University Medical Center of Ho Chi Minh City, answers:

There are currently no studies showing that wearing multiple layers of masks or wearing them too tightly will cause cerebral ischemia; this is merely speculation and conjecture from patients.

Cerebral ischemia is a condition in which blood flow to the brain is reduced, leading to a lack of oxygen and nutrients supplied to the brain. This causes nerve cells to lack the energy to function, affecting the structure, survival, and development of the central nervous system.

There are many causes of cerebral ischemia, such as cerebral atherosclerosis, which means narrowing of the arteries that reduces the amount of blood flowing to the brain, or dyslipidemia, especially high blood lipid levels, particularly in people with hypertension, diabetes, and smoking.

Some typical symptoms of cerebral ischemia include headache, severe headache, dizziness, lightheadedness, unsteadiness, tinnitus, memory loss, and difficulty concentrating.

Therefore, you need to see a specialist to find out the cause of these symptoms and receive appropriate treatment.
