In this scientific review, Dr. Patrick Nemechek of Nemechek Autonomic Medicine (inventor of The Nemechek Protocol™) describes a clinical framework in which chronic depression is best understood as a chronic inflammatory condition in the brain. He explains that what begins as an injury—sometimes emotional, sometimes physical—can become persistent when the body is in an ongoing pro-inflammatory state.
In Dr. Nemechek’s description, depression is not presented simply as a “mood problem” or a character issue. Instead, he emphasizes the physicality of chronic depression: a persistent, heavy “wet blanket” feeling that reflects a brain-based process. He also notes that grieving and sadness can still occur even after recovery from an episode of depression—highlighting an important distinction between normal emotional responses and prolonged depressive symptoms.

Dr. Nemechek’s central claim: chronic depression reflects chronic inflammatory brain injury
Dr. Nemechek states that “more and more evidence” over the prior 5–6 years has supported the idea that chronic depression is actually a chronic inflammatory condition in the brain. In his explanation, the underlying issue involves cellular damage in a part of the brain that controls emotions. He notes that in animal models this damage can be seen under a microscope, and that in adults with chronic depression, related changes can be seen indirectly using specialized scans available in research settings.
Within his framework, the clinical question becomes: why do some people recover after an emotional or physical insult, while others remain stuck in a chronic depressive state? His answer centers on whether ongoing inflammation prevents effective repair.
How emotional trauma can become an “injury” that triggers depressive symptoms
Dr. Nemechek connects depression to concepts he discusses in autonomic medicine, including how the autonomic nervous system can be damaged by physical injuries, inflammatory injuries, and even emotional trauma. He gives the example of Broken Heart Syndrome and Takotsubo Cardiomyopathy as a clear instance of an emotionally driven form of damage involving the sympathetic branch of the autonomic nervous system.
He then applies a similar injury-based lens to depression. An intensely negative emotional event—such as the unexpected death of a close friend—may, in his description, cause cellular damage in the brain region associated with common features of depression. Importantly, he differentiates between (1) an expected grief response and (2) persistent depressive symptoms that do not resolve.
Why some episodes resolve: recovery after emotional brain injury
According to Dr. Nemechek, if a person does not have a chronic inflammatory problem and has not developed issues such as bacterial overgrowth, the brain can recover from this emotional brain injury. In that scenario, he says depressive symptoms may lift within weeks (and “a couple months at most”). The person may still grieve and feel sadness when thinking about the individual, but the ongoing depressive “wet blanket” can fade as recovery occurs.
Depression after concussion: a physical injury pathway
Dr. Nemechek notes that depression is also well understood to occur after a concussion (a blow to the head). In his explanation, the reason is consistent with the same core theme: brain cells are damaged, including cells in the region that helps control emotions, and a person can end up with depressive symptoms.
This reinforces his broader point: depression can be triggered by different categories of injury (emotional trauma or physical trauma), yet the downstream problem may converge on inflammatory damage and impaired recovery.
Why depression becomes chronic: “Inflamma-Ageing” and impaired repair
Dr. Nemechek emphasizes that chronic depression is more likely to persist when a person has metabolic inflammation, which he also refers to as “Inflamma-Ageing”. He describes this as a chronic production of pro-inflammatory cytokines in the bloodstream, which can penetrate the brain.
In this pro-inflammatory state, he suggests that the brain may not fully recover after an injury because the repair process doesn’t work properly. He likens this to his discussion of autonomic damage failing to recover when an inflammatory process is present. In his account, inflammatory cytokines interfere with repair mechanisms, including stem cell function and neurotrophins, and he notes there may be additional mechanisms not yet discovered.
When there is no obvious trigger
Dr. Nemechek also references an interesting observation from a study in women: about a third of women with chronic depression reportedly could not identify the emotional trigger. He notes that, in that group, inflammatory markers in the bloodstream were very high. In his interpretation, this supports the idea that “pure, raw” metabolic inflammation may be sufficient to drive dysfunction in brain regions tied to depressive symptoms.
He specifically names the hippocampus as a brain region that can become dysfunctional in this inflammatory context, resulting in symptoms of chronic depression.
Dr. Nemechek’s practical takeaway: address inflammation and gut factors
Dr. Nemechek concludes with a practical, protocol-oriented message consistent with his broader clinical approach: he recommends getting high-dose DHA fish oil and olive oil “on board,” and working to fix the gut. He emphasizes persistence and expresses optimism that this can be turned around over time.
Because individual needs vary and depression can be complex, readers should discuss any evaluation or treatment plan—including supplements and gastrointestinal concerns—with a qualified clinician who can provide personalized guidance and safety monitoring.
