Depression can affect all of us. It can be mild or a debilitating disease that disrupts a person\u2019s life. Do you suffer from depression? Are you aware of some little-known causes that could help you to resolve your depression?<\/span><\/p> In this blog on depression, you will learn:<\/span><\/p> WHAT IS DEPRESSION?<\/strong><\/p> Depression is\u00a0a constant feeling of sadness and hopelessness. Depressed people often lose interest in the normal activities of daily life. Symptoms can range from relatively minor to severe.<\/span><\/p> Depression is a disorder of the brain and can be a serious mental illness. In some cases, depression can persist for months or years and interfere with everyday life.<\/span><\/p> WHAT ARE THE SYMPTOMS OF DEPRESSION?<\/strong><\/p> Not all depression is the same. It is a complicated disorder and there are different subtypes. Common symptoms of depression:<\/span><\/p> Physically, a person may:<\/span><\/p> Socially, a depressed person may avoid contact with friends or family and\u00a0avoid joining social activities. They may neglect work, relationships,\u00a0hobbies or interests. Being depressed can lead to having difficulties in home, work or family life.<\/span><\/p> Depression can be a silent disease. Almost 60% of people with depression do not seek medical help (<\/span>Chand SP, 2023<\/span><\/a>). There is a stigma that depression, or any mental health disorder, is not socially acceptable.\u00a0<\/span><\/p> WHAT CAUSES DEPRESSION?<\/strong><\/p> For years, it was thought that depression was due to low serotonin levels. But the serotonin theory of depression has been disproven. Recent research says there is \u2018no consistent evidence of an association between serotonin and depression\u2019 and there is \u2018no support for the hypothesis that depression is caused by lowered serotonin activity or concentrations\u2019 (<\/span>Moncrieff et al, 2022<\/span><\/a>).<\/span><\/p> Worse still, long-term use of SSRI medication (Selective Serotonin Reuptake Inhibitors), or \u2018antidepressants\u2019, may actually lower serotonin concentration.\u00a0<\/span><\/p> Despite this evidence, many medical and mental health professionals are not up to date and continue to practice as if depression is primarily connected with neurochemical imbalances.<\/span><\/p> Furthermore, antidepressants are not terribly effective:<\/span><\/p> So, if not serotonin depletion, what does cause depression?<\/span><\/p> Clearly,\u00a0external social and environmental factors can trigger depression. Having experienced trauma, abuse, deprivation, extreme stress, a major accident, loneliness, divorce, death of a loved one, financial difficulties and many other difficult life events can all contribute to depression.<\/span><\/p> But there are often physiological root causes for depression. In Functional Medicine, we seek to identify and treat these root causes to help our patients recover from depression. This makes the body more resilient in handling the stresses and challenges of modern daily life.\u00a0<\/span><\/p> Neuroinflammation\u00a0<\/strong><\/p> Emerging research shows that neuroinflammation is a key issue in depression. Neuroinflammation is inflammation in the brain. When the brain is inflamed, depression or other neurological or neuropsychiatric conditions can present.\u00a0<\/span><\/p> Inflammation in the brain negatively affects brain health. Mood disorders such as depression, <\/span>anxiety<\/span><\/a>, autism, dementia \/<\/span>Alzheimer\u2019s<\/span><\/a> and schizophrenia have all been linked to <\/span>inflammation in the brain<\/span><\/a>.\u00a0<\/span><\/p> There is significant research on the \u2018cytokine theory of depression\u2019. This says that inflammatory proteins called cytokines in the bloodstream cross the blood-brain barrier (BBB) and cause neuroinflammation. This neuroinflammation activates microglia cells in the brain and can cause depressive symptoms.\u00a0<\/span><\/p> Microglia cells are immune cells of the brain that regulate brain development. They play important roles in brain health and inflammation.\u00a0Microglia protect against diseases such as meningitis and Alzheimer’s.\u00a0But they can also be harmful. The chronic activation of microglia may cause\u00a0neuronal damage. This is because they release proinflammatory cytokines and others molecules that contribute to neuroinflammation.<\/span><\/p> Of course, the next question is, what is the cause of the inflammatory cytokines and resulting neuroinflammation?\u00a0<\/span><\/p> Infection as a trigger for neuroinflammation<\/strong><\/p> Infections and toxins impact mental health via the mechanism of neuroinflammation. An infection or toxin can affect the brain. The infection or toxin can get into the brain, often through a <\/span>leaky blood brain barrier<\/span><\/a>. Once in the brain, they can initiate neuroinflammation and a brain autoimmunity process that leads to mental health dysfunction.<\/span><\/p> What is the link between infections, antibodies against brain tissue and inflammation?<\/span><\/p> In simple terms, when the immune system is combating some infection, the protein structure of the infectious organism may look a lot like some brain tissue. The immune system is trying to fight the infection and inadvertently starts to attack brain structures in the process.\u00a0<\/span><\/p> If the infection becomes chronic or the autoimmune process continues, changes to brain chemistry and neuroinflammation that result from the brain autoimmunity can cause the onset of mental health disorders.\u00a0<\/span><\/p> The 5 main infections causing mental illness are:<\/strong><\/p> Strep throat<\/span><\/em><\/p> A strep throat infection can be the trigger for neuropsychiatric symptoms in childhood such as anxiety, obsessive-compulsive disorder and tic disorders. As a result of the infection, antibodies against brain tissue are created, which cause structural damage to the brain, neuroinflammation and symptoms.<\/span><\/p> Lyme disease<\/span><\/em><\/p> Lyme is a bacterial infection, caused by the bacterium Borrelia burgdorferi. Borrelia is most commonly spread via tick bites. Lyme disease is a complex inflammatory disease with both acute and potentially chronic symptoms.\u00a0<\/span><\/p> When left untreated, undiagnosed or misdiagnosed, Lyme disease can possibly develop into more serious symptoms.\u00a0 It can cause inflammation in the brain and mood symptoms. Neuropsychiatric problems such as anxiety, depression, panic and OCD can develop.\u00a0<\/span><\/p> Lyme co-infections<\/span><\/em><\/p> A Lyme disease co-infection occurs when someone is infected with other diseases transmitted by the same tick. A tick can carry disease-causing microbes or co-infections in addition to Borrelia. Once bitten, it is possible to contract Lyme and one or more co-infections simultaneously. Possible Lyme co-infections include Bartonella, Anaplasmosis, Babesiosis, Powassan virus, Borrelia miyamotoi (relapsing fever-like illness) and Ehrlichia muris (which causes ehrlichiosis) (<\/span>Eisen, 2018<\/span><\/a>).\u00a0<\/span><\/p> Mold illness<\/span><\/em><\/p> Mold is a significant and under-examined issue that contributes to chronic inflammation and illness. Mold toxins, or mycotoxins, are biotoxins that can cause illness. Exposure to molds, mycotoxins and water-damaged buildings can cause neuropsychiatric symptoms and inflammation. Some symptoms of mold illness include pain, fatigue, increased anxiety, depression and cognitive issues when exposed to a moldy environment (<\/span>Harding CF, 2020<\/span><\/a>).\u00a0<\/span><\/p> Viral infections<\/span><\/em><\/p> Viral infection can be a significant cause of illness, inflammation, immune problems and mental health issues. Different types of viruses, including Epstein-Barr Virus (EBV), herpes, Covid, the flu, HPV and chickenpox \/ shingles have been associated with mental illnesses (<\/span>Canli, 2014<\/span><\/a>).\u00a0<\/span><\/p> Viral infections are never fully eliminated from the body like most bacterial infections are. Viral infections remain dormant in the body. A virus can be re-activated at any time. It can become a low-level chronic infection, even after the acute symptoms resolve.\u00a0<\/span><\/p> Stress is one of the main triggers for reactivation. When the immune system becomes overwhelmed by something else, a virus can re-activate. Being under constant stress can make the immune system too weak to fight the virus off. It can then develop into a chronic underlying viral infection. Encephalitis, or inflammation of the brain, is commonly caused by a viral infection like herpes simplex virus (<\/span>Ellul M, 2018<\/span><\/a>).<\/span><\/p> Bacterial or parasitic infections and exposure to toxins (mold toxins or toxic heavy metals) can trigger the reactivation of latent viral infections. Other viruses such as COVID-19 may be able to reactivate dormant viruses like Epstein-Barr Virus. Chronic viral infections can cause neuroinflammation or brain antibodies that can lead to depression, anxiety and mental health issues.<\/span><\/p> One study found that any history of hospitalization for infection is associated with a 62% increased risk of later developing a mood disorder, such as depression and bipolar disorder (<\/span>Benros ME, 2013<\/span><\/a>).<\/span><\/p> Exposure to Toxins as a source of neuroinflammation<\/strong><\/p> Toxin exposure can have extreme health consequences both in the short term and the long term. Exposure to toxins can be a cause of mental health disorders.<\/span><\/p> Toxins create neuroinflammation, cause damage to tissue and brain function, interfere with important inter-cellular communication, disrupt the gut and the gut\/ brain axis and can possibly change DNA. Toxins damage genes and gene expression by possibly turning on harmful genes and\/or turning off beneficial ones. All of these effects can lead to depression.\u00a0<\/span><\/p> Please see our recent blog <\/span>here<\/span><\/a> for more info on the danger of excessive toxin exposure.<\/span><\/p> In addition to infections and toxins, what are other sources of neuroinflammation?<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t Do you have a chronic or mystery illness that no one has been able to help you with? Are you simply wanting to re-connect with a healthier version of yourself? It’s Time To Finally Feel Better!<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Gut Issues<\/span><\/em><\/p> A little-known fact is that gut issues can cause mental health issues. Imbalances in the gut can contribute to depression, anxiety and a lower stress resilience.\u00a0<\/span><\/p> \u00a0<\/p> Gut dysbiosis is a cause of mental illness. Dysbiosis is an excess of bad gut bacteria in relation to good and healthy gut bacteria in the gut microbiome. Gut dysbiosis usually causes digestive symptoms and can contribute to depression. Dysbiosis can be caused by many things; a poor diet, stress, antibiotics, other medications, alcohol and other toxins that change the normal microbiome balance and contribute to dysbiosis.<\/span><\/p> \u00a0<\/p> During dysbiosis, the gut brain axis is dysregulated. The blood-brain barrier becomes more permeable. Bad gut bacteria produce more LPS toxins, which cause inflammation. This inflammation, due to LPS and other microbes, increases pro-inflammatory cytokines (<\/span>Rutsch A, 2020<\/span><\/a>). With a permeable BBB, these cytokines and toxins get into the brain, leading to neuroinflammation and inflammatory gut\/brain conditions, such as depression (<\/span>Rutsch A, 2020<\/span><\/a>To Read About Blog Topic, Scroll Down<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
