These drugs, although useful for treating severe cases of depression that may manifest as CNS depression, can easily be misused. The medications above depress the functions of the spinal cord and brain, both vital components of the central nervous system. In cases of misuse due to addiction, accidents, or unregulated dosage increases, individuals can very easily slip into unconscious coma states because neural activity drops below safe levels. The hippocampus, that plays a major role in neuronal growth, is rich in BDNF. It also plays an important role in neuronal survival and maturation, dendrite arborization, and synaptic neuroplasticity in the brain of adults. Stress suppresses BDNF synthesis in the hippocampus, while antidepressants increase synthesis by sending signals to PFC and hippocampus.
Given their strength and addictive qualities, only people who have a severe condition should use them. But, high doses of these drugs can reduce the activity of the CNS to dangerously low levels. If you have a medical condition that puts you at risk for CNS depression, talk to your doctor.
Child-resistant containers and pump bottles that deliver a small amount of product limit access to large quantities. Washing hands with soap and water is also a low risk and effective alternative. Where hand sanitiser is used, young children should be closely supervised. Older children should be taught to use hand sanitiser safely and effectively. While this study was unable to differentiate between liquid and gel formulations, this is an area for further research. An overdose of a CNS depressant can happen by accident, but people sometimes choose to take more of the drug than a doctor recommends to get a more “intense” effect.
What are the symptoms of CNS depression?
In the majority of cases, children in our study were able to be managed at home under the supervision of an adult. However, it is important to note that isolated cases of central nervous system depression following ingestion of an alcohol-based hand sanitiser have been described in other countries, including the US 8. This highlights the importance of storing topical antiseptics, including hand sanitisers, out of reach of children. This is particularly important for younger children who are more likely to be unintentionally exposed than older children and are at greater risk of toxicity. Other measures to mitigate child exposure include keeping hand sanitisers in their original labelled containers to reduce the risk of accidental ingestion.
The hippocampus is also the area where neurogenesis continues in the mature brain, being the area with high neuroplasticity. Opposition central nervous system depression disorder in childhood causes decreased hippocampus, impaired neurogenesis, impaired glial cells, synaptic impairment, all of which ultimately lead to HPA axis dysfunction. MRI studies support low hippocampal volume in adults known as former abused children.
Sleep medication
Recreational use can be illegal and dangerous, as people may not understand the risks of misuse. A drug called flumazenil can reverse the serious effects of benzodiazepines. A variety of other things in your environment can lead to CNS depression when ingested or inhaled. One such product is ethylene glycol, a chemical found in a variety of consumer goods, including antifreeze and de-icing products. When ingested, this chemical is toxic to the CNS, kidneys, and heart.
What Causes CNS Depression?
- ▪ Depression with peripartum onset is an intense depression that leads to disability, sometimes felt only after birth, but often, at a close look, symptoms are identified during pregnancy.
- Usually, awaiting the metabolic removal of the agent while supporting the respirations is adequate treatment.
- It also plays an important role in neuronal survival and maturation, dendrite arborization, and synaptic neuroplasticity in the brain of adults.
- These are sometimes prescribed prior to surgery to you help relax during the procedure.
The patients with late-onset depression after treatment with Fluoxetine or Reboxetine have shown an improvement in memory and attention. The limitations of this study come from the absence of a control group that was treated with placebo 33. Stress can cause atrophy of both the hippocampus and PFC, with morphological changes in both regions being observed in patients with depression. Under these conditions, an ideal antidepressant should prevent cortical atrophy and stimulate the mechanisms of neurogenesis. Some studies that examine the volume of the hippocampus in patients with a long history of depression, find correlations with the time spent by the patient in symptomatic conditions.
- All of the above support the association between dysfunctional pathology of PFC and MDD.
- These are strong pain-relieving drugs that come from opium, a substance made from the seeds of the poppy.
- Treatment is respiratory support and, if necessary, cardiovascular support.
Many CNS depressants work by increasing the activity of the neurotransmitter gamma-aminobutyric acid (GABA), a chemical that prevents or slows the delivery of messages between cells. CNS depressants are medications and other substances that slow down the CNS. Combining different CNS depressants, such as painkillers and alcohol, can be life-threatening. Store medicines, alcohol, and other potentially hazardous materials safely away from children and pets.

There is a hyperactivity of the amygdala when the depressed patient is exposed to negative stimuli but also a hypoactivity at this level when the person in question benefits from positive stimuli. Post-mortem studies performed on patients with MDD have shown both a low number of glial cells and an alteration of their morphology, which is mainly found in PFC compared to other regions of the brain. The results suggest that glial function is deficient or even compromised in PFC and represents the anatomical substrate of depressive symptoms. We are talking here about a junctional intercellular communication that involves a gap between sections, a noticeable gap in astrocytes and which in turn leads to changes in neural function in PFC 18. Barbiturates are powerful medications, and over time medical professionals have shifted from using them to treat anxiety and sleep disorders to being used as anticonvulsants (anti-seizure medications). The autonomic nervous system and the HPA axis are directly related to the concept of stress.
The correlation reinforces the hypothesis that SSRIs reduce the symptoms of depression through the mechanism of neurogenesis. Excessive CNS depression is when the central nervous system slows down to notable or even dangerous levels. Harmful levels of CNS depression are caused by the misuse of CNS depressants, which are drugs used to treat conditions like anxiety and sleep disorders.
Anxiety and Depression
In major depression, there is a hyperactivity of the white matter in the territories related to the frontal cortex and basal ganglia. Post-mortem in major depression, a reduced number of glial cells was found in the PFC; here there is also a dysfunctional junctional intercellular communication, which consists in a visible decrease in the transmission of the signal between astrocytes. Depression involves hyperactivity in the limbic areas where emotions are processed, with inhibition of the prefrontal areas. Hyperactivity is found especially in the amygdala, correlating directly with ruminant tendencies, intrusiveness, and adjacent anxiety. The hippocampus, which has numerous receptors for corticosteroids, is responsible for reactive-mediated emotional responses to life situations.
Alcohol and Sedatives
Any event that causes decreased blood flow and oxygen to the brain, such as a severe heart attack can also lead to CNS depression. 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. This is why these medications specifically prohibit you from drinking alcohol while taking them.
