What Is The Definition Of Clinical Depression?

What Is The Definition Of Clinical Depression?

The Albany Clinic • December 28, 2021

It’s normal to feel sad or depressed in certain situations. It’s a part of life that everyone deals with occasionally. Typically, such feelings or low moods subside naturally, but when symptoms persist for weeks, even with treatment, you may be suffering the early signs of clinical depression.

What Is Clinical Depression?

Clinical depression is a major medical illness that adversely affects how you think, the way you feel, and your actions. People with clinical depression can’t function as they used to, often losing interest in once enjoyable activities and feeling hopeless and sad for a long time. It can affect the body, behavior, moods, and thoughts. Depression changes eating habits, how you feel and think, studying and working, and interactions with other people.

Important Facts

The consequences of clinical depression can’t be understated. Besides ranking as a top mental health condition in America, it has a broad reach worldwide.

  • Globally, nearly 300 million people across multiple groups experience depression.
  • The World Health Organization (WHO) calls it a leading cause of disability globally and a big supplier to the total global weight of disease.
  • Depression affects more women than men.
  • Depression can result in suicide.

The WHO says, “There are effective psychological and pharmacological treatments for moderate and severe depression.” Years of research have uncovered the potential of unique medicinal options, including ketamine, a popular anesthetic.

Is It Different From Stress And Sadness?

If you or a loved one is depressed, you’ve likely heard someone say, “Shake it off, you’re just sad” or “Stress sucks.” Feeling depressed and sad is often a typical reaction to something stressful going on in your life. Look at it like this – it’s common to have a low mood following a big disappointment or to experience problems sleeping or eating after ending a personal relationship. Typically, after talking to a friend or loved one, you begin to feel like yourself again within a short time. But clinical depression is far different. It’s typified by a noticeable shift in how you function, with common symptoms like irritability and loss of sleep lingering for two weeks or more.

These are typical experiences that some people can have when suffering from clinical depression, but the condition manifests itself differently for each person. Unlike normal sadness and stress, the signs of clinical depression linger and don’t subside no matter how much you wish otherwise. That’s often when you know it’s time to get help.

Signs And Symptoms

  • Feelings of tearfulness , sadness, hopelessness, emptiness.
  • Anger, irritability, or frustration, even over tiny issues.
  • Loss of interest in pleasurable activities, like sex, hobbies, or sports.
  • Difficulty sleeping – including insomnia – or sleeping more than average.
  • Tiredness and lack of energy, resulting in abnormal effort.
  • Weight loss and less hunger or boosted cravings for food resulting in weight gain.
  • Anxiety, restlessness, or agitation.
  • Slower thinking, speech, or bodily motions.
  • Feelings of guilt or worthlessness, obsession with past failures.
  • Problems thinking, concentrating, memory, and decision making.
  • Preoccupation with thoughts of death, suicide, or suicide attempts.
  • Inexplicable physical ailments, like headaches or back pain.

Causes

Research is ongoing, but doctors and scientists believe clinical and other depression are caused by changes within the brain, specifically with neurotransmitters and how cells communicate. Depression may result from genetics like a blood relative who’s depressed, biological processes , temperament, stressful events, and even environmental factors.

How To Diagnose

At a minimum, getting diagnosed with depression requires a physical exam and psychiatric evaluation, as well as lab tests and other diagnostics to look for a root cause. Your healthcare provider will then consult with the Diagnostic and Statistical Manual of Mental Disorders , Fifth Edition, most recently updated in 2013.

Types Of Treatment

Many psychological and pharmacological treatments are available to treat clinical depression, most prominently in-patient or out-patient counseling or medicine prescribed by a licensed healthcare provider. Effective care depends on many factors, including the severity of the depression, overall physical health, history of mental illness, and your commitment to whatever treatment is recommended. In some cases, doctors and clinicians may recommend innovative treatments like ketamine – which was introduced as an anesthetic in the 1960s.

Final Thoughts

Clinical depression is a severe mental health illness that can lead to dangerous health problems, including an increased risk of suicide. It can never be cured, but different kinds of treatment can help manage its most prevalent symptoms. Call us today to learn more about innovative new treatments like ketamine infusions that may be able to help you find relief.

Stellate Ganglion Block (SGB) for Depression

By Kimberly Mercille • May 27, 2025
Stellate Ganglion Block (SGB) is an emerging mental health treatment that targets key mechanisms linked to depression. In this article, we’ll discuss the science behind SGB and its potential benefits. If you or someone you know is struggling with depression, this information can help you make an informed decision about whether SGB might be the right option. What is a Stellate Ganglion Block (SGB)? What is the Stellate Ganglion? The stellate ganglion is a cluster of sympathetic nerves located on each side of the neck near the first rib. These nerves are part of the autonomic nervous system, which controls automatic body functions like heart rate, blood pressure, and digestion. The term "stellate" means "star-shaped" because the ganglion often looks like a star under a microscope. It helps regulate the body's stress response by controlling norepinephrine, a chemical that triggers the fight-or-flight reaction. When this system becomes overactive, it can cause various physical and psychological problems, including depression. Stellate ganglion block (SGB) therapy may help by reducing the activity of the stellate ganglion, calming the fight-or-flight response, and lessening the damaging effects of prolonged nervous system stress. How Does Stellate Ganglion Block Work? Stellate Ganglion block (SGB) is when a local anesthetic is injected near the stellate ganglion. These drugs inhibit transmission between nerve cells, dampening activity in the ganglion. They typically include lidocaine, bupivacaine, or mepivacaine, which are sometimes combined with a steroid medication. Patients may also receive another medication to relax them before treatment. SGB is typically performed using ultrasound guidance . The injection process lasts no more than 10 minutes, but patients will motinoted for another 30-45 minutes after treatment to ensure their safety. How Does Stellate Ganglion Block Work for Depression? Chronic stress is a major contributor to depression and is often linked to an overactive sympathetic nervous system. People with depression commonly show high levels of cortisol, a hormone that plays a key role in the body's stress response, in their blood stream. Cortisol is helpful in small doses, but when chronically elevated, it can disrupt neural circuits in the brain. Excessive cortisol can lead to: Neurotoxicity - Cortisol can be toxic to nerve cells, especially in the hippocampus, which is crucial for memory and emotional regulation. Overinflammation - Cortisol increases the activity of the body’s natural defense system, resulting in the system causing damage to nerve cells. Impaired synaptic plasticity - Cortisol inhibits the capacity for the brain to “re-wire” itself. This makes it harder for people to adapt to stressful situations and learn new patterns of behaviour. Disrupted sleep - High cortisol can prevent people from sleeping well. During sleep, restorative biological processes occur in the brain, and excess cortisol can prevent these from happening. SGB decreases sympathetic nervous system activity, which can reduce cortisol levels. This can help restore function in brain areas and pathways associated with positive mood, emotional regulation, and stress resilience. Evidence Supporting SGB for Depression To date, there’s very limited evidence supporting the use of SGB for depression. One pilot study found that SGP significantly reduced depression symptoms in people with treatment-resistant depression (TRD) and was well-tolerated. However, there was no significant difference to the placebo group and the sample size was very small. Nonetheless, multiple lines of research show that SGB can alleviate symptoms of post-traumatic stress disorder (PTSD), which shares similarities with depression. In a trial of SGB for PTSD , participants reported significantly lower scores of depression following treatment. Who May Benefit from SGB for Depression? SGB is primarily utilized for treating PTSD, so individuals with PTSD who also experience depression may find SGB beneficial. Additionally, SGB has shown potential in alleviating anxiety symptoms, suggesting it may be advantageous for those dealing with both depression and anxiety. Because SGB isn’t approved by the FDA, it is typically only used when standard treatments like antidepressants and psychotherapy haven’t worked. SGB is an “off-label” treatment, much like ketamine therapy or brain stimulation therapies. Importantly, SGB may not be suitable for everyone because of medical reasons. Contraindications include: Recent myocardial infarction Coagulopathy or anticoagulant therapy Glaucoma Pre-existing contralateral phrenic nerve palsy Severe emphysema Cardiac conduction block Potential Risks and Side Effects of SGB Common Side Effects Most side effects of SGB are temporary and resolve as the anesthetic wears off. These may include: Hoarseness or Voice Changes: The proximity of the stellate ganglion to nerves controlling the voice box can lead to temporary hoarseness. Drooping Eyelid (Ptosis): Temporary drooping of the eyelid on the side of the injection may occur. Red or Bloodshot Eyes: Some individuals may notice redness in the eyes following the procedure. Watery Eyes and Nasal Congestion: Increased tearing and nasal stuffiness are possible but typically short-lived. Sensation of a Lump in the Throat and Difficulty Swallowing: Some individuals may experience a sensation of a lump in the throat and have difficulty swallowing after the procedure. Warmth or Tingling in the Arm or Hand: A warm or tingling sensation in the affected limb may be experienced temporarily. Although uncommon, some individuals may experience more serious complications, such as nerve damage, seizures, and allergic reactions. Given the potential risks, patients interested in SGB at the Albany Clinic will have an in-depth consultation with one of our qualified healthcare professionals before undergoing treatment. They can assess your medical history, current health status, and the potential benefits and risks of the procedure in your specific case.

SGB for Long COVID: Can a Nerve Block Help Ease Symptoms?

By Matt Rodriguez • May 7, 2025
Long COVID is a condition in which symptoms–such as brain fog, fatigue, and shortness of breath—persist for months after a COVID-19 infection. Researchers are still working to understand why this happens and how to treat it. One potential therapy being explored is the stellate ganglion block (SGB) , a procedure that numbs a cluster of nerves in the neck. In the article, we’ll explore the science behind SGB and long COVID and the evidence supporting its use.

Insurance-Backed Options for Depression Treatment in Illinois

By Matt Rodriguez • April 1, 2025
Finding effective depression treatment can be challenging, especially when cost and insurance coverage add to the stress. Fortunately, for individuals in Illinois, several advanced, insurance-backed options are available beyond traditional antidepressants and therapy. This article explores innovative treatments for depression that are available at our Albany Clinic in Carbondale. Addressing the Need for Affordable Depression Relief in Illinois Depression remains a significant public health concern in Illinois. In 2023, data showed that 18.1% of all adults in the state had a doctor's diagnosis of a depressive disorder . Traditional first-line treatments for depression include medications such as selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). However, these are not universally effective; approximately one-third of patients are treatment-resistant. Even when these medications do work, they often take a long time to produce noticeable improvements, and unpleasant side effects can deter their use. Talk therapies , such as cognitive behavioral therapy (CBT) and psychodynamic therapy, are also strongly recommended. These treatments can have hugely beneficial effects, but it can require a lot of time commitment for results to show. Moreover, not all therapists accept insurance–especially for those practicing more specialized forms–making the treatment inaccessible for many. Spravato (Esketamine) for Depression What is Spravato, and how does it work? Spravato is an FDA-approved nasal spray that contains esketamine, a derivative of ketamine. Like ketamine, esketamine treats depression by interacting with NMDA receptors , proteins that play a key role in learning and memory. This interaction triggers several neurological processes, including neuroplasticity —the strengthening and forming of connections between nerve cells. Enhanced plasticity may improve the function of nerve circuits responsible for mood regulation, increasing overall well-being. A typical Spravato treatment involves sessions administered under medical supervision, starting with twice-weekly doses and then tapering as appropriate. Whereas antidepressants typically take around four weeks to show an effect, Spravato can have rapid action at alleviating symptoms. A study found that Spravato significantly reduced depression symptoms compared to a placebo drug within just 24 hours of administration. Does Insurance cover Spravato? Due to its FDA approval, Spravato is covered by most major insurance plans in Illinois, including Medicare and Medicaid. However, only patients with a formal diagnosis of treatment-resistant depression (TRD) or major depressive disorder with suicidal ideation (MDSI) are eligible for the treatment. While the medication is usually covered by insurance, patients may still have out-of-pocket costs , including copays , deductibles , and pre-treatment medical evaluations . Your exact expenses will depend on your specific insurance plan. At the Albany Clinic, we’re here to help you understand your costs and maximize your coverage. Transcranial Magnetic Stimulation (TMS) Therapy What is TMS, and how does it work? TMS therapy is a noninvasive procedure that uses magnetic fields to stimulate underactive regions of the brain associated with mood regulation. In depression, TMS targets the dorsolateral prefrontal cortex (DLPFC) , which is often less active in individuals with the condition. TMS therapy works by: Inducing electrical activity in neurons , prompting the release of neurotransmitters involved in mood and motivation. Increasing the activity of neural circuits responsible for mood regulation. Enhancing neuroplasticity , potentially “re-wiring” nerve circuits associated with unhealthy thinking and behavior. The treatment protocol typically consists of daily sessions over several weeks. Each session lasts about 20-40 minutes, during which patients remain awake and alert. Does insurance cover TMS? Since TMS therapy is FDA-approved, some major insurance providers in Illinois cover costs, but unfortunately, the state’s Medicaid does not. If you're considering TMS, check with your insurance provider to see if your plan includes coverage, as eligibility and benefits vary. At the Albany Clinic, we're here to help clarify details and explore options to make treatment more affordable. IV Ketamine Infusion Therapy What is an IV ketamine infusion and how does it work? IV ketamine infusion therapy involves administering ketamine intravenously at sub-anesthetic doses . This approach has shown rapid and robust antidepressant effects, especially in individuals with treatment-resistant depression. IV ketamine shares the same mechanism as Spravato but tends to have more rapid-acting effects. A standard course includes multiple infusions over a set period, with each session lasting approximately one hour. Does insurance cover IV ketamine? Unlike Spravato and TMS, IV ketamine infusion therapy is not FDA-approved for depression treatment and instead is used “ off-label .” This means most insurance plans don’t accept ketamine, and coverage is limited. However, some insurance companies may reimburse some of the treatment costs, such as the evaluation and management part. At the Albany Clinic, we’ll provide you with all the documentation to submit a claim to your insurance provider, but full payment is required before each procedure. Navigating Insurance for Depression Treatment Understanding insurance coverage for depression treatments can be complex. Here are steps to help streamline the process: Verify Coverage : Contact your insurance provider to inquire about treatment coverage specifics. Some insurers require a history of treatment failures with traditional antidepressants before approving coverage for these advanced therapies. Obtain Pre-Authorization : Many insurers require pre-authorization for certain treatments. Ensure all necessary approvals are secured before initiating therapy. The Albany Clinic's administrative team can assist in submitting pre-authorization requests. Understand Financial Responsibilities : Clarify any co-pays, deductibles, or out-of-pocket expenses associated with your treatment plan. Consult Our Team : The Albany Clinic's administrative staff is experienced in navigating insurance processes and can assist you in understanding and managing the financial aspects of your treatment. We also provide financial counseling to help patients explore payment plans and reimbursement options.
