Blood Biomarkers Are Emerging As Important Tools
Professor Niculescu said: Through this work, we wanted to develop blood tests for depression and for bipolar disorder, to distinguish between the two, and to match people to the right treatments.
Blood biomarkers are emerging as important tools in disorders where subjective self-report by an individual, or a clinical impression of a health care professional, are not always reliable. These blood tests can open the door to precise, personalized matching with medications, and objective monitoring of response to treatment.
How Does The Blood Test For Depression Work
The team have created a blood test that is composed of RNA biomarkers, to understand how severe a patients depression is. They can also read the blood test to see if the patient could develop severe depression in the future, while looking at the risk of bipolar disorder too.
While this blood test looks at biomarkers to understand a persons mental health, it can also give highly specific advice about what kind of pharmaceutical treatment would work best for that individual.
Creatinine And Blood Urea Nitrogen
Creatinine and BUN levels reflect how well the kidneys are working. Not only can kidney disease lead to symptoms similar to depression, but its also important for doctors to know if kidney function is impaired before prescribing an antidepressant. When the kidneys arent working well, they may not be able to metabolize certain medications properly.

Does A Bipolar Person Know When They Are Manic
So no, not everyone who has bipolar disorder knows they have it. There are lots of reasons why someone with bipolar disorder might not realize itâor why they might deny having it even if they do.
On top of that, some alterations, based upon cognitive screening, were made to boost comprehension. Additionally, although titles similar to those made use of in the NCS-R were used for the NSDUH modules, the outcomes of these products may not be straight similar. The prevalence of significant depressive episode was greater among teenage females can stress depression cause cancer compared to males . The prevalence of major depressive episode was greatest among those that report having numerous races . The prevalence of significant depressive episode was higher amongst adult women compared to men . Indicators of depression in men may include impatience, temper, or alcohol and drug misuse.
- Though the device for just how it works isnt well understood, its believed to affect exactly how the mind functions, which consequently can reduce depressive episodes.
- While it is not completely comprehended why seasonal affective disorder happens, there are a number of concepts that project.
- Seasonal depression, or SAD, is a form of depression that happens certain months of the year.
- Without therapy, symptoms can last for weeks, months, and even years.
Tests Already Available To Diagnose Mental Health
Major mental health conditions are also linked to physical problems. For instance, here are a few routine blood tests doctors recommend to diagnose depression.
- Cholesterol level
- Liver functions
- Blood sugar level
In most cases, depression crops from underlying physical ailments and simple medication for these disorders can improve the symptoms.
Just like depression, any mental health conditions diagnosis starts from understanding and analyzing the patients physical state. Getting to know bodily functions is one of the basic steps in this direction.
Apart from lab tests, doctors spend a lot of time with the individuals who are affected to get to know them better. This helps them understand the mental state of patients and build a history of their mental conditions with more detail. Conversation is a vital aspect of mental health treatment as it helps with building the route map for the diagnosis.
Apart from standard test reports, the following parameters help doctors assess a clear picture of your mental health.

Does This Latest Study Offer A Conclusive Test For Bipolar Disorder
It may seem like an exciting development that a simple blood test can potentially diagnose bipolar disorder. But when asked if a blood test can provide conclusive evidence of bipolar disorder, Dr. Jeffrey Ditzell, a psychiatrist in private practice in New York City, answers in the negative.
Not yet. The test assay is currently being used to differentiate proBDNF that is potentially neuroinflammatory, from mBDNF that is considered neuroprotective, Ditzell told Healthline.
The test uses a cutoff for serum mBDNF levels of fewer than 12.4 nanograms per milliliter. This represents progress from previous tests, offering support for a clinical diagnosis of MDD or bipolar disorder.
However, Ditzell goes on to say that the blood test is unlikely to shift the diagnostic criteria for bipolar disorder in the near future.
The BDNF levels can be helpful, but the diagnosis of the condition of bipolar disorder remains a clinical one, and the tests, though supportive, should not be considered as confirmatory, at this time.

What Happens During Depression Screening
Your primary care provider may give you a physical exam and ask you about your feelings, mood, sleep habits, and other symptoms. Your provider may also order a blood test to find out if a disorder, such as anemia or thyroid disease, may be causing your depression.
During a blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
If you are being tested by a mental health provider, he or she may ask you more detailed questions about your feelings and behaviors. You may also be asked to fill out a questionnaire about these issues.
Blood Test Offers New Hope To People With Depression
The test would avoid the years of trial and error that currently characterise diagnosis and treatment of mental health conditions.
A blood test using RNA markers is offering new hope to people with mood disorders such as depression in what could be a significant breakthrough in the diagnosis of mental health conditions.
A team from the USs Indiana University School of Medicine launched the blood test in April, claiming it to be psychiatrys first-ever biological answer to diagnosing a mood disorder.
Our study shows that it is possible to have a blood test for depression and bipolar disorder, that have clinical utility, can distinguish between the two, and match people to the right medications, said psychiatrist and geneticist Dr Alexander Niculescu, who led the research.
This avoids years of trials and error, hospitalisations, and side-effects. As these are very common disorders, we think we can do a lot of good with this and other tests and apps we have developed.
The study delved into the biological basis of mood disorders, developing a tool to distinguish which type of mood disorder a person has depression or bipolar disorder.
To develop the test, Dr Niculescus team drew on its 15 years of previous research into how psychiatry relates to blood gene expression biomarkers measurable indicators of a biological state in the form of RNA, DNA, proteins or other molecules.
Conversely, an immune activation or inflammation would affect the brain.

MAJOR DEPRESSION is a serious illness, but also an elusive one. It wrecks lives and may drive people to suicide. It sometimes, though not always, alternates with periods of mania in a condition called bipolar disorder. And it is disturbingly common. Reliable figures are hard to come by, but in some parts of the world as many as one person in four experiences major depression at some point during their life.

Depressions diagnosis has, though, a worryingly arbitrary quality to it, depending as it does on a doctors assessment of a patients mood against a checklist of symptoms which may be present in different combinations and are often, in any case, subjective. This has led to a search for reliable biochemical markers of the illness. Not only might these assist diagnosis, they may also improve assessments of prognosis and point towards the most effective treatment in a particular case. Now, a group of neuroscientists at Indiana University, in Indianapolis, led by Alexander Niculescu, think they have found a set of markers that can do all this.
Why A New Physical Test For Depression May Be Nothing To Crow About
Posted May 17, 2012
I always thought that the idea of a physical test for depression was intriguingand also a big challenge. After all, while depression is real, it’s also a construct. As often as we hear that depression is a “disease,” the fact is that it’s not a disease like chicken pox or strep throat. It isn’t caused by a germ and we can’t see it under a microscope. To a large extent, depression is what we’ve decided it is. So what would a blood test for depression actually measure?
Given all that, my ears pricked up at a recent headline in the Atlantic magazine’s online technology section:
“Study of the Day: Blood Tests Can Accurately Diagnose Depression.”
The post described a study co-authored by George Papakostas and John Bilello, published in the journal Molecular Psychiatry.
The study looked at 79 adults, 36 with a diagnosis of major depression, and 43 without. The patients’ blood was screened for nine biomarkers associated with depressive symptoms, including inflammation, the development of neurons, and the interaction of various brain structures. Based on these readings, each patient was given a figure called an “MDDScore,” a number between 1 and 100, indicating the likelihood that the patient has major depression.
The study successfully predicted a diagnosis of depression in 33 of the 36 depressed patients, and generated eight false positives for the group of 43 healthy patients.

What Are Blood Biomarkers
Blood biomarkers are a naturally occurring characteristic in the blood, which can be read almost like signs into the health of a human. Reading biomarkers has been common for diseases and cancers, but bringing them into the field of mental health is relatively new.
Now, the team believe they know how to use blood biomarkers to read a patient for depression and bipolar disorder.
Professor Niculescu commented: We have pioneered the area of precision medicine in psychiatry over the last two decades, particularly over the last 10 years. This study represents a current state-of-the-art outcome of our efforts. This is part of our effort to bring psychiatry from the 19th century into the 21st century.
To help it become like other contemporary fields such as oncology. Ultimately, the mission is to save and improve lives.
Through this work, researchers found 26 biomarkers that tell them about a persons state of mind both present and future.
Blood Test For Depression Bipolar Disorder Offers Promise Of Personalized Treatment
For Immediate Release
INDIANAPOLIS — Worldwide, 1 in 4 people will suffer from a depressive episode in their lifetime.
While current diagnosis and treatment approaches are largely trial and error, a breakthrough study by Indiana University School of Medicine researchers sheds new light on the biological basis of mood disorders and offers a promising blood test aimed at a precision-medicine approach to treatment.
Led by Dr. Alexander B. Niculescu, professor of psychiatry at the IU School of Medicine, the study was published today in the journal Molecular Psychiatry. The work builds on previous research conducted by Niculescu and his colleagues into blood biomarkers that track suicidality as well as pain, post-traumatic stress disorder and Alzheimer’s disease.
“We have pioneered the area of precision medicine in psychiatry over the last two decades, particularly over the last 10 years. This study represents a current state-of-the-art outcome of our efforts,” Niculescu said. “This is part of our effort to bring psychiatry from the 19th century into the 21st century, to help it become like other contemporary fields such as oncology. Ultimately, the mission is to save and improve lives.”
First, the participants were followed over time, with researchers observing them in both high and low mood states. Each time, the researchers recorded what changed in terms of the biomarkers in their blood between the highs and lows.

Why You Should Demand Blood Tests From Your Psychiatrist
Unless you test, youve guessed.
I’ll admit – when I originally started trying to figure out my depression, I also did a lot of guessing and not enough testing.
That made things much more difficult, and I ended up making a lot of mistakes along the way.
That’s why I recommend you test more, and guess less.
Otherwise, its hard to know for sure what steps you should take to correctly treat and overcome your depression.
The underlying issues that contribute to depression are different for everyone.
But blood testing can show you the inner functioning of your body, highlight your physiological abnormalities, and help you identify the underlying root causes of your depression so that you can address them using nutrition, supplements, therapies and other lifestyle factors.
Below are 13 important blood tests that you should get done if you struggle with depression.
These blood tests shine light on some of the real, underlying root causes of depression, and will give you helpful information to act upon.
When something is outside the optimal range, you can then do something about it!
They put the power back into your hands, and give you a much better idea of where you should begin, so that you can get better faster, and overcome your depression sooner rather than later.
What Is The Method Used To Detect Mental Health Conditions With Blood Tests
Dr Niculescu and his team were conducting this research for 15 years and through their earlier research on how psychiatry relates to blood gene expression biomarkers, they were able to withdraw measurable biological indicators. They found the way to study the bodys biological state owing to mental ailments through its representation on the RNA, DNA, proteins and other molecules of the human body.
Basically, the team has revealed that every system of your body, be it the brain, the nervous system, digestive system or the immune system, alters considerably when you are facing mental ailments. Scanning bodily functions right up to the cellular level helps in mapping the diseases at play. To put it simply, RNA markers are derived through blood tests. As they may tell the story of individual mental health problems, similar RNA markers are grouped. Thus, the researchers claimed to have easily spotted mental health issues like bipolar disorder and depression.
Keeping Dr Niculescu and his teams undying efforts as the backdrop, the next level of research is being carried out by the prestigious CLIA in the USA. This is where the findings are being put to test and after some rounds of clinical testing, we will know how much merit blood tests can get for the quick detection of mental ailments.

Scientists Develop New Blood Test That Could Diagnose Your Level Of Depression
A newly developed system that monitors for blood biomarkers linked to mood disorders could lead to new ways to diagnose and treat depression and bipolar disorder, all beginning with a simple blood test.
While depression has been recognized for centuries and affects hundreds of millions of people worldwide, the traditional diagnosis still depends on clinical assessments by doctors, psychologists, and psychiatrists.
Blood tests might inform such health assessments, to check whether symptoms of depression might be related to other factors, but they’re not used in clinical practice to objectively and independently diagnose the condition itself. The new research suggests this could be a practical option in the future.
In the new study, researchers have identified 26 biomarkers measurable and naturally occurring indicators in patients’ blood variably linked to the incidence of mood disorders including depression, bipolar disorder, and mania.
Dr. Alexander B. Niculescu.
“Blood biomarkers are emerging as important tools in disorders where subjective self-report by an individual, or a clinical impression of a health care professional, are not always reliable,” says psychiatrist and neuroscientist Alexander B. Niculescu from Indiana University.
“These blood tests can open the door to precise, personalized matching with medications, and objective monitoring of response to treatment.”
“Ultimately, the mission is to save and improve lives.”
If The Diagnosis Is Depression
Depression is treatable. Consequently, a depression diagnosis can start you on the road to a healthier life without feelings of helplessness, hopelessness, and worthlessness.
Once your doctor makes a depression diagnosis, you need to follow the treatment program to get better. It’s important to take the medications as prescribed. You also need to follow through on making lifestyle changes and working with a psychotherapist if that’s what your doctor recommends. Millions of people with depression suffer needlessly because they don’t get professional help that starts with a doctor’s diagnosis.
