These substances work by slowing down brain activity, leading to CNS depression, which can be caused by overdoses, poisoning or medical conditions. Misuse of CNS depressants can lead to serious consequences, including dependence and life-threatening situations, especially when combined with other substances like alcohol. These drugs, along with alcohol and opioids, carry risks for addiction and are often misused for their euphoric effects. There are currently no FDA-approved medications to treat sedative, hypnotic or anxiolytic use disorders.
How can a CNS depressant overdose be treated?
When people overdose on a CNS depressant, their breathing often slows or stops. This can decrease the amount of oxygen that reaches the brain, a condition called hypoxia. Hypoxia can have short- and long-term mental effects and effects on the nervous system, including coma and permanent brain damage. They not only reduce anxiety and induce sleep but also slow down essential bodily functions, which can be dangerous in high doses. Currently, most barbiturates are classified as Schedule III controlled substances, although some types, such as phenobarbital, are Schedule IV instead.
- These substances are typically unregulated and can be easily purchased or found in products around the house.
- The sedative Xyrem, known as the “date rape drug,” commonly features in cases of sexual assault.
- Suddenly stopping can also lead to harmful consequences like seizures.
- Now that we have covered stimulants, it is time to move on to drugs that have opposing effects.
They can also lower heart rate, breathing, and blood pressure, which, in large doses, can lead to death. Barbiturates are misused when they are taken in a way or dose that’s different than prescribed or taken without a prescription. Barbiturates are depressants that have been used to treat seizure disorders, insomnia, and anxiety. Anabolic steroids are misused when they are taken in a way or dose that’s different than prescribed or taken without a prescription.

- You may also be at higher risk if you have existing respiratory problems such as emphysema and sleep apnea.
- They are sometimes sold as LSD but are more potent with higher risk of severe effects.
- Nicotine replacement therapy products include gum, patches, sprays, inhalers, and lozenges.
- Although they have a lower risk of dependency than other CNS depressants, long-term use may cause the condition.
- Treatment often involves gradually reducing the dosage of CNS depressants under medical supervision to prevent withdrawal symptoms.
Nicotine replacement therapy products include gum, patches, sprays, inhalers, and lozenges. NBOMes (N-Benzylphenethylamines) are lab-made (synthetic) chemical compounds originally developed for use in brain research. They are sometimes sold as LSD but are more potent with higher what is a cns depressant risk of severe effects. Methylphenidate is misused when it is taken in a way or dose that’s different than prescribed or taken without a prescription. People may misuse methylphenidate to get “high,” to improve school performance, or to help lose weight by reducing appetite. People who misuse loperamide may develop a substance use disorder.
How do people take amphetamines?
The symptoms of withdrawal from loperamide have not been well studied. People who use flunitrazepam may develop a substance use disorder. Dissociative drugs can temporarily alter a person’s mood, thoughts, and perceptions of reality. These drugs primarily affect how the brain processes a chemical called glutamate.

By binding to areas other than the orthosteric site of the receptor, they enhance GABA activity. In particular, they increase the amount of time that the chloride ion channel remains open when GABA binds to the receptor. At high concentrations, barbiturates can also bind to the main site as direct agonists.
One of the latest neuromodulation therapies available at UTSW’s Peter O’Donnell Jr. This therapy uses external magnets and coils to depolarize affected neurons, “resetting” the connected networks to restore normal function. Since then, a brain imaging revolution has swept the field of psychiatry, steering away from solely observation-based diagnoses and toward imaging-guided treatment plans. Sophisticated magnetic resonance imaging (MRI) and computed tomography (CT) imaging helped us better understand brain anatomy.
Benzodiazepines, also known as Benzos, are also used to treat anxiety and sleep disorders, although they are considered less addictive than barbiturates. Xanax, Valium, and Prosom are some of the most common types of Benzodiazepines. There are many hypotheses for depression, including neurochemical imbalance, altered regional brain activity, inflammation, nutritional, and endocrinal reasons. Evolving concepts about depression emphasize altered activity in different brain circuits and regions. For purposes of depression, certain brain circuits – default, salience, negative and positive affect, cognitive control, and attention circuits – are important. There are currently no FDA-approved medications to treat tianeptine-related substance use disorder.
We recently began a unique inpatient program for accelerated TMS therapy that delivers 10 treatments a day. This means a full course of treatment can be completed in just five days. In teens, use of nicotine may cause changes to the development of the parts of the brain that control attention and learning.
Consequently, the barbiturate-tolerant individual keeps increasing the dose needed for euphoria until it catches up with the lethal dose. Inhalants, which we will also be examining, do not have any sleep-inducing effects. At the same time, some drugs produce sedative effects through mechanisms other than the GABA receptor. Antihistamines, one such example, act at histamine receptors and cause drowsiness as a side effect.
Severe symptoms can lead to coma, respiratory suppression, and death. If you have anxiety or a sleep disorder your doctor may prescribe you a CNS depressant, such as a sedative, to help relieve your symptoms. In certain cases, CNS depression could also be caused by a stroke, brain trauma, an aneurysm, or a tumor. Some research shows that even conditions that don’t directly affect the brain, like diabetes or kidney and heart disease, could cause CNS depression. Another major cause of CNS depression in people who have no history of using CNS depressants is brain injury.
This blog post aims to illuminate the complexities of CNS depression, its causes, and how it differs from other forms of depression. We’ll explore the science behind CNS depressants, their risks, and treatment options. By the end, you’ll understand why seeking professional help is crucial and how it can make a difference in the lives of those affected. If you have a medical condition that puts you at risk for CNS depression, talk to your doctor.
Synthetic cathinones, also known as bath salts, are a class of lab-made stimulants chemically related to substances found in the khat plant. Khat is a shrub grown in East Africa and southern Arabia that some people consume for its stimulant effects. People who use synthetic cannabinoids may develop a cannabis use disorder.
Mild symptoms may include drowsiness and impaired coordination, while more severe symptoms can involve respiratory depression, coma, and death. Central Nervous System depressants are substances that slow down brain activity, producing a calming effect. Ultimately in severe cases, CNS depression causes unconsciousness and coma. Mild CNS depression due to prescription medication is to be expected and isn’t necessarily a problem if sedation is desired. However, if you feel too sluggish or overly sleepy while taking medications that depress the CNS, talk to your doctor.
