When any kind of chemical is killing brain cells, are there any symptoms?

Question

Be it drugs, auto exhaust, pesticides, dioxins, heavy metals, chemicals, etc...... Is there anyway to know if these chemicals are being introduced into your bloodstream, wherein courtesy of circulation, are being distributed into the body's organs, when exposure occurs? Would you pass out before any damage is done?

I realize that there are two types of exposure... acute, and chronic. Acute is when a transient effect is generated by a singular, yet strong exposure to a substance. With chronic toxicity, you can be in the environment for years before any real symptoms manifest, because the poisoning is very slow.

As far as acute toxicity goes, unless you develop a substantial migraine, vomit, or pass out, does this mean that something has had no effect on the body, and even if some inhalation has occurred, it's completely negligible and the body is equipped to discard itself of the chemicals with no repurcussions? Not a single brain cell lost?

Answer 1

There are probably 1000 cells in every part of your body dying every second.  It is estimated that you have over one trillion (1000 billion) cells in your body.  Most of the time, when the cells die they are replaced by mitosis (cell division).

The cells that are still alive form new connections, helping

the brain to still function well. Things like drugs, laughing gas, smelling paint thinners, and alcohol can increase the brain cell death rate to up to 300, 000 a day.

A mix of THC, the main mood changing drug in marijuana / cannabis, and mildly intoxicating doses of alcohol caused widespread nerve cell death in the brains of young rats, a German study finds. Rats were used as they have similar biology to humans. Thus, this finding may also occur in people who drink and use marijuana.

A previous study by the same team found that ethanol and drugs such as sedatives, anesthetics and anticonvulsants caused extensive nerve cell death in the brains of young rodents.

Hope This Helps :)
