Drug Abuse and Irreversible Brain Damage

Posted by DrugFreeHomes in Alcohol Abuse, Drug Addiction, Prescription Drug Abuse, Steroid Abuse, Tobacco Abuse on December 22nd, 2009

In our lives, it is a well-known and sometimes unaccepted fact that all things change. While the good parts in life may not last as much as we would like them to, be relieved that the opposite also applies: the bad things in life don’t last forever either. With this in mind, we must stand resilient against life’s challenges and find ways to move forward.

brainThis nugget of wisdom may be true, but in the context of brain damage caused by drug abuse, it’s a different story altogether. You may think that the process is reversible, but it is actually not. Most are probably thinking that our brain can just go back to the way it used to be if we have absolutely no contact with drugs for a prolonged period of time after a few episodes with drugs – just like getting some sleep to relieve yourself of fatigue or recovering from a dreadful hangover. Well, most are wrong.

If it were that easy, then it will be perfectly okay for everybody to do drugs and be heedless of the consequences of the act. However, our brain’s neurons do not restore themselves the way the rest of our body does. Anything that adversely affects our mental capacity and physical state is dangerous for our brain, and drugs are especially guilty in this case.

So before you even think about getting your fix or trying drugs for the first time, consider the long-term effects first. Is it really worth losing your mind over? Is it really worth wasting your life for?

How Drugs Affect the Brain?

The human brain, in very simplistic terms, has two parts – the neocortex which is located in front of the head and which receives, processes and stores information for decision making and for remembering.

The other part is the limbic system whose function is to control all the automatic systems of the body and the emotions. It also controls the survival responses, i.e. in a threatening situation it tells you to adopt “fight or flight” responses, i.e., either to defend yourself or run away from the situation.

Drugs and alcohol program the limbic system to avoid uncomfortable situations instead of making healthy responses to resolve the associated stress and the Cortex protects such faulty behavior pattern by a filtering process called denial. The result is the addictive brain.

A communication system exists within the brain whereby the information is received and processed. The individual brain cells or neurons communicate with one another through neurotransmitters or biological messengers. Psychoactive drugs change the normal pattern of communication in two ways:

  • By  imitating the brain’s natural communication
  • By overstimulating the brain’s reward system with dopamine

The chemical structure of drugs like marijuana and heroin is similar to that of neurotransmitters. Thus they can easily deceive the brain receptors and activate nerve cells to send abnormal messages. Cocaine and methamphetamines, on the other hand prevent the recycling of brain chemicals by releasing large amount of neurotransmitters. This blocks the signal between the neurons and the amplified message thus produced, disrupts the normal communication patterns.

Almost all drugs target the dopamine secretion which is normally related with emotions and feelings of pleasure. When overstimulated, it produces euphoric effects in response to drugs thereby reinforcing the habit of abusing drugs.

Artificial stimulation of the brain undoubtedly leads to irreparable damages in the brain cells.

Would you compromise your BRAIN for DRUGS?

Make a healthy choice, stay away from drugs.
