    Neuroinflammation: The Biological Root of Mental Illness

    Neuroinflammation — the activation of the brain's resident immune cells, the microglia, in response to blood-brain barrier disruption, systemic inflammatory signals, heavy metal accumulation, viral or bacterial insult, or oxidative stress — is now recognised by leading neuroscientists as the primary biological driver of depression, anxiety disorders, bipolar disorder, schizophrenia, and the majority of conditions currently categorised as psychiatric illness. Pro-inflammatory cytokines including IL-1β, IL-6, and TNF-α cross the blood-brain barrier and directly inhibit tryptophan hydroxylase (reducing serotonin synthesis), disrupt dopamine signalling, and impair hippocampal neurogenesis — the biological mechanisms of the mood disorders for which the NHS prescribes SSRIs and antipsychotics without addressing the underlying inflammatory aetiology. This paradigm shift from chemical imbalance to immune-inflammatory models of mental illness has profound and largely unimplemented implications for psychiatry.
