As a neurologist with more than 16 years of experience, I have seen hundreds of patients – from young to old – come to the clinic with fatigue, persistent headaches, insomnia, memory loss, or even seizures or strokes without warning. They often come when the condition is severe, when the nerve damage has been silently developing for many years.

Our brain accounts for only about 2% of our body weight, but consumes up to 20% of the oxygen and 25% of the energy produced by the body. Each nerve cell is like a "signal station" that continuously transmits information, helping us think, move, remember and control all life functions. Therefore, any problem with the brain and nervous system can seriously affect the quality of life.
