Study links brain cells to depression
Major depressive disorder is a significant medical condition that leads to a variety of serious emotional and physical problems. New research further highlights the potential implication of astrocytes in depression.

It is hoped these findings will guide targeted treatment options for those suffering from this debilitating disorder. (2021-02-04)

Single brain region links depression and anxiety, heart disease, and treatment sensitivity
Over-activity in a single brain region called the subgenual anterior cingulate cortex (sgACC) underlies several key symptoms of mood and anxiety disorders, but an antidepressant only successfully treats some of the symptoms. A new study, published today in the journal Nature Communications, suggests that sgACC is a crucial region in depression and anxiety, and targeted treatment based on a patient's symptoms could lead to better outcomes. (2020-10-26)

Ketamine, a painkiller used by the army, does not impair tolerance to blood loss
A low dose of ketamine, administered intravenously, does not alter a healthy human's tolerance to blood loss. In other words, if someone was given ketamine to kill pain associated with a battlefield injury, they would be able to tolerate blood loss just as well as someone who did not received this pain killer. (2020-10-21)

New study finds antidepressant drug effective in treating "lazy eye" in adults
In a new study, published in Current Biology, researchers from the University of California, Irvine School of Medicine reveal how subanesthetic ketamine, which is used for pain management and as an antidepressant in humans, is effective in treating adult amblyopia, a brain disorder commonly known as ''lazy eye.''

Depression risk detected by measuring heart rate changes
For the first time doctors have shown that measuring changes in 24-hour heart rate can reliably indicate whether or not someone is depressed. In practical terms, this may give clinicians an objective ''early warning'' of potential depression, as well as a rapid indication whether or not treatment is working, so opening the way to more rapid and responsive treatment.

High doses of ketamine can temporarily switch off the brain, say researchers

Their findings, which are published in Translational Psychiatry, give hope of new, effective antidepressants. (2020-05-31)

Scientists find brain center that 'profoundly' shuts down pain
A Duke University research team has found a small area of the brain in mice that can profoundly control the animals' sense of pain. Somewhat unexpectedly, this brain center turns pain off, not on. It's located in an area where few people would have thought to look for an anti-pain center, the amygdala, which is often considered the home of negative emotions and responses, like the fight or flight response and general anxiety. (2020-05-18)

Ef­fects of rapid-act­ing an­ti­de­press­ants con­sol­id­ated in sleep?
Ketamine alleviates depressive symptoms within hours, with the most significant change typically seen a day after its administration. However, the symptoms often reappear within a week. According to researchers at the University of Helsinki, neural connections strengthened by the quick treatment of depression are consolidated in the brain during the deep sleep periods of the following night. To prevent the circle of negative thoughts regaining supremacy, depressed patients also need therapy. (2020-04-22)

JNK protein triggers nerve cells to withdraw their synapses when stressed
New study from Eleanor Coffey's lab at Turku Bioscience Center in Finland identifies that the JNK protein triggers nerve cells to withdraw their synapses when stressed. (2020-03-11)

Scientists have discovered how a genetic alteration that increases the risk of developing Autism and Tourette's impacts on the brain. Their research also suggests that ketamine, or related drugs, may be a useful treatment for both of these disorders. Deletion of the Neurexin1 gene affects brain areas involved in Autism and Tourette's including the thalamus, a collection of brain regions that play a key role in helping other brain areas communicate with each other.

FSU research: Ketamine could help men suffering from alcohol use disorder
Research from Florida State University is giving physicians a better understanding of ketamine, a potentially useful tool in treating depression that still has unanswered questions. A team of researchers working in the laboratory of Mohamed Kabbaj, a professor of Biomedical Sciences and Neuroscience in the College of Medicine, showed that ketamine can decrease alcohol consumption in male rats that previously had consumed high amounts of alcohol when given unrestricted access several times a week. (2019-11-19)

Side effects mild, brief with single antidepressant dose of intravenous ketamine
Researchers found that a single, low-dose ketamine infusion was relatively free of side effects for patients with treatment-resistant depression. Widespread off-label use of intravenous subanesthetic-dose ketamine has raised concerns about side effects, especially given its history as a drug of abuse. The most common short-term side effect of the rapid-acting treatment was 'feeling strange or loopy.' (2019-11-18)

Ketamine reduces drinking in male, but not female, rats
The drug ketamine decreases alcohol consumption in male, but not female, rats, according to new research published in eNeuro. The findings suggest that ketamine may be a viable treatment option for male patients with an alcohol use disorder. (2019-11-18)

One in three pain patients suffer side effects after ketamine infusion therapy
As the opioid epidemic continues to devastate the United States, ketamine use has grown as a pain management alternative, yet more than one in three patients may experience side effects such as hallucinations and visual disturbances, suggests new research presented at the ANESTHESIOLOGY® 2019 annual meeting. (2019-10-21)

Colorectal surgery patients who were a part of an enhanced recovery after surgery (ERAS) program had less pain, while using nearly half as many opioids, according to research being presented at the ANESTHESIOLOGY® 2019 annual meeting. (2019-10-19)

Popular pain medication associated with greater risk of hypoglycemia
As the opioid tramadol has grown in popularity so too have documented cases of adverse effects. In a new study, researchers at Skaggs School of Pharmacy and Pharmaceutical Sciences at UC San Diego show that patients who take tramadol are at greater risk for hypoglycemia, abnormally low blood sugar. (2019-08-28)

Ketamine isn't an opioid and treats depression in a unique way
Ketamine has gotten a bad rap as an opioid when there's plenty of evidence suggesting it isn't one, Johns Hopkins experts say. They believe this reputation may hamper patients from getting necessary treatment for the kinds of depression that don't respond to typical antidepressants. In a new paper, the researchers clarify the mechanism behind ketamine's mechanism of action in hopes of restoring the therapy's standing among health care professionals and the public. (2019-07-31)

Study supports effectiveness of new fast-acting antidepressant, esketamine nasal spray
New research supports the effectiveness and safety of esketamine nasal spray in treating depression in people who have not responded to previous treatment. The research will be published online today in the American Journal of Psychiatry. This study is one of the key studies that led to the recent Food and Drug Administration (FDA) approval of esketamine nasal spray, in conjunction with an oral antidepressant, for use in people with treatment-resistant depression. (2019-05-21)

China unlikely to curb fentanyl exports in short-term
China has pledged to crack down on the illicit export of the synthetic opioid fentanyl to the US, but a new analysis finds that may be difficult given the way that China regulates its larger drug and chemical industries. The finding are part of a new report that outlines how illicit drug polices across Asia are changing. (2019-05-15)

Stress in early life could make people more likely to develop depression
New research by the University of Bristol has found that early life adversity could make an individual more at risk of developing negative thinking, which could lead to major depressive disorder (MDD).
