Brain Cells Die Every DayWith the increasing of age, people will experience the death of brain cells that occurs every day. This brain death could not be prevented or even slowed. On average, how many brain cells die each day?

The human brain regulate and coordinates the majority of movement, behavior and homeostatic body functions such as heartbeat, blood pressure, body fluid balance and body temperature. The brain is also responsible for functions such as recognition, emotion, memory, motor learning, and all other forms of learning.

It is estimated that the human brain consists of 100 billion brain cells (neurons) and around 1 trillion supporting cells (glia), which helps neurons. The brain weighs about 1.4 kg (3 pounds). But after the age of 20 years, naturally people will lose about a gram of brain mass per year.

According to, to calculate the number of dead brain cells per day, it takesĀ  mathematical counting from the existing brain cell theories. Here are the facts:

If the human brain has a weight of 1.4 kg (1400 grams) and there were about 100 billion neurons, then it can be calculated that there are approximately 70 million neurons per gram.

Now, when people lose a gram of brain mass per year, meaning that the brain loses 70 million neurons per year, or about 190 thousand damaged, slowing down, or dying brain cells per day.

The counting does not indicate that 190 thousand brain cells actually dieĀ  per day. Some can be caused due to missing or dying glia (support cells). Others caused by the reduced neuronal loss caused by insulation material, myelin, which makes neurons work more slowly, but not dead.

Even if it is said that about 5 percent of one gram of neurons actually die, then the human brain looses about 9000 neuron per day. This number may seem overwhelming, but when compared with the rest of the remaining neurons, this amount is not nothing.

There are many internal factors that can accelerate and multiply the death of brain cells, particularly chemicals, medicines and certain foods.

Not all drugs can cause brain cells to die, but can make it very damaged. Ketamine, nitric oxide and volatile inhalants (which is contained in glue, gasoline and paint thinner) can cause brain cell death 30 times the normal level, or nearly 300 thousand neurons per day.

In addition, exposure to cigarette smoke, alcohol, fast food (junk foods), MSG (Monosodium Glutamate) and illegal drugs can also accelerate and multiply the death of brain cells each day.

Just so you know, the death of brain cells may cause some diseases associated with nerve cells, such as:

  1. Dementia (senility)
  2. Asperger syndrome (the inability to communicate)
  3. Trauma or brain stem damage (traumatic brain injury)
  4. Down syndrome (mental retardation)
  5. Epilepsy
  6. Autism
  7. Psychiatric disorder
  8. Alzheimer’s disease (brain disorientation)
  9. Parkinson’s disease (chronic brain disorders that interfere with movement)
  10. Paralysis
  11. Partial degenerative brain disorder
  12. Szhizoprenia

While a healthy lifestyle such as exercising, healthy eating, exercise your brain or memory exercises can slow brain death so that people do not quickly get senile.

    Well ive died when I was a little kid when I was about 4 months olds. I was laying on the couch passed out. today my brain suck a** I can barely think I hardly can remember anything. I’m always forgetting things even the simple things
