Alcohol Is A Central Nervous System Depressant

So Is Alcohol A Stimulant Or A Depressant

Alcohol as a Central Nervous System depressant

You mightve noticed that we havent put alcohol in either category above. First off, which one do you think alcohol is: a stimulant or a depressant?

Most people think that alcohol is a stimulant. After all, it ramps up your confidence, makes you giddy, and certainly gives you a burst of energy!

Its true that alcohol has some stimulant effects. It does raise your heart rate, along with some other physical changes.

However, these effects are just temporary. Plus, theyre a result of your brain releasing more dopamine after your initial drink. Dopamine is also known as the feel-good hormone, as it can make you feel happy and also lessen pain processing.

Alcohol, is in fact, truly a depressant. Think about how you feel when you drink alcohol, especially in excess you start slurring your words and you have slower reaction times.

As you can see, while alcohol does have some stimulant effects, its scientifically classified as a depressant. Youll typically feel the stimulant effects at a BAC of under 0.05mg/l. But once you go over 0.08mg/l, the depressant effects will take over.

Do note that you should never mix stimulants with alcohol. Doing so can have serious and even fatal results.

What Are The Side Effects Of Alcohol And Other Depressants

When used as directed, or in limited quantities, alcohol and other depressants can provide feelings of relaxation and reduce the symptoms of anxiety. Alcohol and other depressants do lead to intoxication.

Common side effects of alcohol and other depressants include the following:

  • Impaired motor skills and coordination
  • Mental cloudiness and confusion
  • Slowed or stopped heart rate
  • Slowed or depressed breathing
  • Emotional instability and severe mood swings

How Do Cns Depressants Affect The Brain

Most CNS depressants act on the brain by increasing activity of gamma-aminobutyric acid , a chemical that inhibits brain activity. This action causes the drowsy and calming effects that make the medicine effective for anxiety and sleep disorders. People who start taking CNS depressants usually feel sleepy and uncoordinated for the first few days until the body adjusts to these side effects. Other effects from use and misuse can include:

  • problems with movement and memory
  • lowered blood pressure
  • slowed breathing

If a person takes CNS depressants long term, he or she might need larger doses to achieve therapeutic effects. Continued use can also lead to dependence and withdrawal when use is abruptly reduced or stopped. Suddenly stopping can also lead to harmful consequences like seizures.

What Is The Most Depressant Alcohol

A recent study examined how different types of alcohol cause distinct emotional reactions in men and women. The study polled over 30,000 people from 21 nations across the world. Each responder drank other types of wine, spirits, and beer on different occasions and documented how the various types of alcohol affected their mood and feelings.

Respondents were most likely to report feeling relaxed after drinking red wine, although almost half also reported feeling relaxed after drinking lager. However, red wine is also known to make you sluggish. Red wine was voted the most likely kind of alcohol to make people relaxed and lethargic, with 60 percent experiencing drowsiness after a few glasses.

Alcohol As A Stimulant

How Does Alcohol Affect The Central Nervous System ~ galambosdesigns

While alcohol is technically a depressant, when its first ingested, it acts very much like a stimulant. Alcohol triggers the brain to release dopamine, a neurotransmitter that provides energy, stimulation, and good feelings. Dopamine also elevates mood, and it increases the ability to feel pleasure and motivation.

In addition, alcohol has stimulating effects on the rest of the body in low doses. Heart rate and blood pressure increase, as do alertness, confidence, and energy levels. These stimulant effects, though, arent the same for everyone. Body chemistry, weight, age, and sex can all affect alcohol metabolism, as can the extent to which a person has built up a tolerance to alcohol.

As the blood alcohol concentration approaches 0.05 milligrams per liter, its stimulant effects increase. However, by the time a person reaches a BAC of 0.08 mg/l , the depressant effects of alcohol have pushed the stimulant effects aside.

The Symptoms Of Depressant Abuse

Those individuals who abuse depressants will tend to exhibit certain symptoms. These effects can be a warning to friends, colleagues, and family that something is not right. If a person has these symptoms it does not necessarily mean that they have an addiction. There are other physical and mental health problems that could be the cause. It is also not necessary for the individual to have all the symptoms for them to be abusing a drug even a couple of these behaviors could indicate abuse. The most common signs of depressant abuse include:

* Evidence of withdrawal symptoms when the individual is not using depressants* A loss of interest in activities they previously enjoyed* Secretive behavior* Even though these drugs are causing obvious harm the individual continues to use them* Time of work and reduced productivity* Periods of depression* Less interest in personal hygiene and grooming* Mood swings* They cant remember things that happened due to blackouts* They are unable to control the amount of alcohol or other depressant they are using* Denial when confronted with the abuse* The person feels unable to cope without their drug* Poor behavior possibly followed by a period of remorse* Inability to keep up with their family and social commitments

The Opioid Crisis: Some Figures

Since 2000, Americans have died of an opioid overdose. Data for 2016 estimates at least 64,000 drug overdose deaths, the highest number ever recorded in the United States.

Overdoses of prescription painkillers in the U.S. is a growing problem, especially among women, according to the

Treatment for CNS depression or CNS depressant overdose depends on the substances involved.

Some CNS drugs have antidotes that can reverse their effects. These include Naloxone for opioid overdoses and Flumazenil for overdoses of benzodiazepine.

A person may need emergency care if they are unaware that they are experiencing a CNS depressant overdose, especially after accidentally misusing their medication or due to a medical problem.

Anyone witnessing signs of CNS depression or an overdose in another person should call the emergency services or local poison control center for guidance.

In these cases, treatment may include:

  • monitoring the persons breathing and heart rate.
  • giving oxygen via an oxygen mask or respirator
  • administering stimulant drugs to increase a persons heart rate

In the U.S., anyone who is concerned that they or someone they know is misusing CNS depressants can:

  • access the Substance Abuse and Mental Health Services Administration website for help and advice

Effects Of Alcohol On Neurosteroids

Several neuroactive steroids exhibit rapid non-genomic activity in the CNS. These rapid mechanisms of action include the modulation of NMDA and GABAAreceptor activity. Studies have shown that positive or negative allosteric modulators of the NMDA receptor complex bind to distinct sites on this receptor, which differ from the binding sites of glycine, dizocilpine , Mg2 and spermine. Furthermore, pregnenolone sulfate and dehydroepiandrosterone sulfate, which are negative allosteric modulators of the GABAA receptor, act as non-competitive antagonists to reduce the activity of GABAA and glycine receptors, whereas androsterone, progesterone, allotetrahydrodeoxycorticosterone, allopregnanolone, pregnenolone and epipregnanolone act as positive allosteric modulators of this receptor.6262 Barbosa ADE, Morato GS.

Combining Alcohol With Drugs

Alcohol, like benzodiazepines, sedatives, and muscle relaxers, is a CNS depressant. All these substances repress activity in the brain and body. When alcohol is used in combination with another depressant, the risk of life-threatening CNS depression dramatically increases. Moreover, when CNS activity begins to slow to a crawl, the risk of coma and death begets a very real and present danger.

Conversely, stimulants boost activity in the CNS and include substances such as amphetamines, caffeine, and cocaine. Some people use stimulants as they are drinking to reduce alcohols depressant effect and counteract the adverse effects of stimulants, including anxiety, nervousness, and agitation.

Using alcohol with stimulants, however, is potentially even more dangerous. Indeed, people may continue to consume alcohol while still feeling energic and elated from stimulant use under the erroneous belief that he or she is not at risk for other adverse consequences.

However, combining alcohol with short-acting stimulants, such as cocaine, is particularly dangerous, because alcohols depressant effect can continue long after the effects of the stimulant have subsided. In fact, mixing alcohol and cocaine increases the risk of sudden death by 20 times over the use of either substance alone.

Finally, alcohol and other psychoactive drugs can produce serious psychological effects, such as major depression, anxiety, suicidal ideations, irritability, aggression, delusions, and hallucinations.

Why Is Alcohol Not A Stimulant

The Effects of Alcohol on the Nervous System : The Effects of Alcohol ...

The classification of a drug is based on the dominant effects. With alcohol, depressant effects are dominant, so it is considered a depressant.

When determining if a substance is a stimulant or a depressant, doctors look at how it impacts the central nervous system.

  • Stimulants, also known as uppers, speed up the processes of the central nervous system.
  • Depressants, also known as downers, slow these processes down.

Alcohol is interesting because it does both, speeding up and slowing down the CNS at different stages of intoxication. The myth that alcohol is a stimulant began because of its ability to loosen people up and reduce social inhibitions.

Ongoing research theorizes that alcoholics experience either greater stimulant effect or less depressant effects compared to peers.

Is Xanax A Cns Depressants

Xanax is a prescription central nervous system depressant. It is one of the most commonly prescribed psychiatric medications. Shallow sedation, tranquilizers, and hypnotisms are common central nervous system tranquilizers that slow brain activity. Anxiety, panic, acute stress reactions, and sleep disorders are all treated with these medications.

What Is The Nervous System

The term nervous system refers to the interconnected network of nerve cells that provide the body with its most basic physical and mental functions. Some of these cells form the central nervous system , in the brain and spinal cord. The CNS serves as the headquarters for all nerve activity throughout the body. It relies on two basic components: specialized nerve cells called neurons and specialized chemicals called neurotransmitters.

Neurons and neurotransmitters have an interactive relationship. Each individual neuron forms a link in the central nervous systems communications infrastructure. However to send messages, these cells must call on the services of several dozen neurotransmitters. Neurotransmitting chemicals flow back and forth as required, triggering the reactions needed to carry signals to and from the central nervous system.

The central nervous system interfaces with a second network called the peripheral nervous system and includes all other nerves in the body. It carries out instructions issued by the central system and provides critical feedback to guide future CNS activity.

Alcohol And Sleep Faq

Does Alcohol Help You Sleep?

Alcohol may aid with sleep onset due to its sedative properties, allowing you to fall asleep more quickly. However, people who drink before bed often experience disruptions later in their sleep cycle as liver enzymes metabolize alcohol. This can also lead to excessive daytime sleepiness and other issues the following day. Furthermore, drinking to fall asleep can build a tolerance, forcing you to consume more alcohol each successive night in order to experience the sedative effects.

Does Alcohol Affect Men and Women Differently?

This can mostly be attributed to two factors. First, women tend to weigh less than men and those with lower body weights often become intoxicated more quickly. Most women also have a lower amount of water in their bodies than men. Alcohol circulates through water in the body, so women are more likely to have higher blood alcohol concentrations than men after consuming the same amount of alcohol.

How Do Central Nervous System Depressants Work

Depressants impact the gamma-aminobutyric acid neurotransmitter in the brain. When this happens, the brains activity slows, often leading to relaxation, sleepiness, and reduced inhibitions.

There are three specific types of depressants: sedatives, hypnotics, and tranquilizers. Each type works in a slightly different way, but all reduce the activity in the brain. They also work to lower awareness in the brain.

Alcohol Is A Central Nervous System Depressant Alcohol Can Appear To Be A Stimulant Because Initially It Depresses The Part Of The Brain That Controls Inhibitions

A childs brain is continuously developing, right through their teens. In fact, the brains final, adult wiring may not even be complete until well into the twenties. Recent research shows heavy alcohol use may affect brain functioning in early adolescence, even in youths who are physically healthy. Changes like these can impact long-term brain functioning. Think about it this way teens who drink twice a week consistently scored an average of ten percent lower on short-term memory tests, compared to non-drinkers. In other words, the heavy/binger teen drinker is more likely to get a B, while the teen who doesnt drink would be able to get an A.

CEREBRAL CORTEX

Alcohol slows down the cerebral cortex as it works with information from a persons senses. In the cerebral cortex, alcohol can affect thought processes, leading to potentially poor judgment. Alcohol depresses inhibition, leading one to become more talkative and more confident. Alcohol blunts the senses and increases the threshold for pain. As the BAC increases, these effects get more pronounced.

Effects Of Alcohol On Voltage

Alcohol Is A Central Nervous System

Another central action of alcohol related to motor coordination is its effect on voltage-dependent Ca22 Heckmann W, Silveira CM. Dependência do álcool: aspectos clínicos e diagnósticos. In: Andrade AG, Anthony JC . O álcool e suas consequências, uma abordagem multiconcenitual. Barueri: Minha Editora, 2009. p.67-87. channels. These channels play an important role in cell depolarization and repolarization. In addition, they regulate a series of cellular activities, including the release of neurotransmitters. Alcohol mainly acts on L-type calcium channels, inhibiting the opening of these channels. The lower influx of positively charged ions into the cell renders it less excitable, in addition to inhibiting the release of neurotransmitters. A larger number of these channels are found in cerebellum. Therefore, the action of alcohol in this region may explain the motor incoordination such as unsteady gait, attention deficits, and impaired sleep-wake regulation.2929 Zaleski M, Morato GS, Silva VA, Lemos T.
