How Drugs Affect The Brain Alcohol, Benzodiazepines, Barbiturates and other central nervous system depressant drugs act primarily on a neurotransmitter substance known as GABA (Gamma Aminobutyric Acid). GABA is an inhibitory neurotransmitter that makes other neurons less likely to activate.

Does alcohol bind directly to GABA receptors or does i increase GABA release? In brief: See below. Alcohol, shown in black, also binds to the gaba receptors, and increases the quieting effect that gaba has on neurons. Researchers are not sure exactly how it does so, but one theory holds that it causes the ion channels to stay open longer, thus increasing the ion flow. The result is a much greater quieting effect on the brain.

Pain arthritis neuropathy Drinking alcohol can thus cause a thiamine (B1) deficiency. Alcohol also significantly impairs the body's ability to absorb more vitamin B1 and interferes with its necessary chemical reactions in the body. Thiamine deficiency can cause a painful neuropathy of the extremities, it is nerve damage. Some researchers believe that alcohol consumption may, in itself, contribute directly to nerve damage. Alcohol is attracted to the membranes of the nerve cells. This membrane is called the myelin sheath. The myelin sheath surrounds each nerve cell. The alcohol thus affects their function. When a sensory nerve is damaged in this way, you get the tingling, pain and numbness. When a motor nerve is damaged, it impairs the bodies motor functions. This disorder is termed alcohol induced neuropathy.

- (See Etiology.). During withdrawal from alcohol, the loss of GABA-A receptor stimulation causes a reduction in chloride flux and is associated with tremors, diaphoresis, tachycardia, anxiety, and seizures. In addition, the lack of inhibition of the NMDA receptors may lead to seizures and delirium.ess than 50% of alcohol-dependent persons develop any significant withdrawal symptoms that require pharmacologic treatment upon cessation of alcohol intake. The lifetime risk for developing delirium tremens (DTs) among chronic alcoholics is estimated at 5-10%.

Impacts of Drugs on Neurotransmission Cocaine, for example, attaches to structures that regulate dopamine, leading to increases in dopamine activity and producing euphoria; it also produces changes in norepinephrine and glutamate systems that cause stimulant effects. Because a neurotransmitter can stimulate or inhibit neurons that produce different neurotransmitters, a drug that disrupts one neurotransmitter can have secondary impacts on others.

Alcohol and Your Brain Let's find out more about the effect that alcohol has on the nervous system and the brain. The Central Nervous System (CNS) The CNS is responsible for taking in information through the senses, motor function, thinking, understanding, and reasoning. This system also controls emotion. The CNS includes the brain, the spinal cord, and the nerves that come from it. The most important parts of the CNS are protected by bones. The skull protects the brain, and the spine protects the spinal cord. Alcohol is a depressant of the CNS. That means that alcohol makes nerve cells in the brain less excited, causing them to slow down.

Alcohol's Effects in the Brain The effects of alcohol on the brain do not end when alcohol is completely metabolized and out of the system--what happens next is something called neurotransmitter rebound. This rebound effect is most easily illustrated if we look at what happens to many people when they use a drink or two as a sleep aid.

- Sugar in particular can temporally raise serotonin and dopamine levels in the brain. So, when you remove the main substance upon which a person has become dependent to feel good or normal (alcohol), the brain screams to get that relief from other substances (carbs and sugar, caffeine and nicotine, pot, etc.).

What Alcohol Really Does to Your Brain Alcohol directly affects brain chemistry by altering levels of neurotransmitters — the chemical messengers that transmit the signals throughout the body that control thought processes, behavior and emotion. Alcohol affects both “excitatory” neurotransmitters and “inhibitory” neurotransmitters. An example of an excitatory neurotransmitter is glutamate, which would normally increase brain activity and energy levels. Alcohol suppresses the release of glutamate, resulting in a slowdown along your brain’s highways.

- The primary mechanism by which alcohol affects brain function is  via its interaction with a class of inhibitory receptors, called  'GABA receptors' (GABA stands for Gamma-A…minoBuytric Acid, which is  a type of inhibitory neurotransmitter).

Alcohol and the Body Alcohol is a central nervous depressant. In short, alcohol depresses, or slows down the body’s central nervous system (CNS). As one’s blood alcohol level goes up, the effects of the depressant become more pronounced. As intoxication increases, cognitive processing slows and motor coordination decreases. This is because the brain is part of the CNS, and is affected by alcohol.
