Neurochemical grounds of addiction: The exhausted GABA

In order to understand the neurochemical grounds of addiction, it is important that we first understand how GABA operates. And to do so, we are going to speaking to doctor Dalal Akoury MD, President, and founder of the AWAREmed health and wellness resource center. And the submission she brakes the understanding as follows.

  • The neurons
  • The central nervous system (CNS)
  • Inhibitory neurotransmitters
  • Excitatory neurotransmitters

Having discussed the first two previously, we are going to progress with the remaining as follows:

Neurochemical grounds of addiction: Inhibitory Neurotransmitters

  • Some neurotransmitters act like a brake on a car.
  • They inhibit or slow down the actions of the neurons.
  • These are called inhibitory neurotransmitters.
  • Other neurotransmitters act like an accelerator.
  • They increase the speed of the actions of the neurons. These are called excitatory neurotransmitters.
  • GABA is the major inhibitory neurotransmitter in the brain.

Neurochemical grounds of addiction: Excitatory Neurotransmitters

  • Excitatory neurotransmitters are vital to:
    • Help us stay alerted
    • Maintain our normal memory functions
    • Maintain our co-ordination
    • Maintain normal emotional responses
    • Maintain our heart rate
    • Maintain our blood pressure
  • Glutamate (a common amino acid) is the major excitatory neurotransmitter in the brain.

Which neurotransmitters are released?

  • If there is something that creates:
    • Anxiety
    • A feeling of panic
    • Other stress
  • Excitatory neurotransmitters are released and a person can feel:
    • Restlessness
    • Higher than normal irritability
    • Rapid heartbeats
    • High blood pressure
    • Insomnia
    • Even seizures.

The role of GABA in the brain

  • Glutamate speeds things up and when they are going too fast, GABA slows them back down.
  • If there is a problem with the GABA in our brains, the neurons fire more and more, increasing the speed of the processes in the brain?

Neurochemical grounds of addiction: How GABA works

When GABA binds to a nerve cell receptor, it opens the nerve cell so that chloride ions present in the brain are allowed to move into the nerve cell to slow the activity of the cell, and the person normally experiences a calming feeling. For example, if our brain produces more excitatory neurotransmitters like norepinephrine or epinephrine (adrenaline) than normal, we can become anxious or have more stress than normal. And when the brain is working normally, it will produce more GABA thereby slowing down the actions in the brain and thus have a calming and relaxing effect on us.

Finally, this article will go a long way in helping you do the right thing with your life. In doing so certain professional decisions will have to be made and to do this, seeking for the expert opinion will be necessary. And that is where doctor Dalal Akoury and her team of experts come in. the lever of professionalism at this facility (AWAREmed health center) speaks for itself since doctor Akoury’s practice focuses on personalized medicine through healthy lifestyle choices that deal with primary prevention and underlying causes instead of patching up symptoms. This is what you need and calling her on telephone number 843 213 1480 should be your starting point for the total life transformation.

Neurons signals and addiction

May 13, 2017
Neurons signals

Neurons signals and addiction. In fact, neurons are the primary communication unit of the brain and must not be contaminated with drugs

Neurons signals and addiction: The brain chemistry

The neuron is the primary unit of communication within the brain. A single neuron is extremely tiny. Experts are estimating that there are over 100 billion neurons in the human brain. With that, you can imagine just how complex and distinct your brain is from the person next to you. And because good communication is of two ways where we both listen (receive information) and at the same time we also speak (send information). The same is applicable to the brain’s communication system with the neurons having the ability to both send and receive communication signals. The dendrite is the portion of neuron signals that typically receives information (listens) while the axon is a portion of the neuron signals that sends out information (speaks).

Neurons signals and addiction: Neurotransmitters

When humans communicate with each other, we typically use words and gestures. The different parts of the brain communicate with each other using electrical signals. Neurons use electrical pulses to send their communication signals. These electrical impulses are called action potentials. When neuron fire, the action potential travels down the neuron’s axon where it ends. At the end of the axon is the axon terminal or pre-synapse. In this area, special chemical messengers called neurotransmitters and neuromodulators lay in wait. These are stored in specialized capsules called vesicles. The action potential causes the release of these chemical messengers into an open space between one neuron’s axon and the next neurons’ dendrites. This open space is the synaptic cleft. At the other side of the synaptic cleft is the post-synapse that is formed by the dendrites of connecting neurons. In the post-synapse, there are special receptors that receive the neurotransmitters.

Receptors and neurotransmitters function in a way that is similar to a keyhole and key. Receptors are like keyholes and neurotransmitters are like the keys. When neurotransmitters fit into the receptors it is called binding. Once a neurotransmitter is bound to a receptor, the key turns the lock. Once the lock opens, it communicates with the receiving neuron’s dendrites. In the post-synapse, there may be many different receptors (many different shaped keyholes). However, a particular neurotransmitter may be able to fit into (bind to) several different receptors types. This is similar to the way a single key can open several different locks. The particular receptor type determines the type of signal that is transmitted. Thus, the receptor type is often more critical to the communication than the particular neurotransmitter.

It may be easiest to visualize this communication as a single chain of events: First, a neuron sends an electrical impulse (action potential) down the axon. Next, the electrical impulse causes chemicals (neurotransmitters and neuromodulators) to be released into space between two neurons. Then these chemicals can signal the next neuron to send an electrical impulse and so on. This electrochemical process forms the brain’s communication system. In conclusion, it is evident that the functions of the brain in communication are very sensitive and any alteration caused by drugs addiction can have far-reaching effects. Therefore before we get there, we must do all it takes to prevent or correct as soon as it is necessary. For this reason, it will be prudent that you schedule an appointment with doctor Dalal Akoury MD a veteran addiction expert who is also the founder of AWAREmed Health and Wellness Resource Center for the commencement of your addiction recovery process.
