A groundbreaking study published in <em>The Journal of Neuroscience<\/em> reveals that <strong>inflammation-induced histamine<\/strong> can reduce the effectiveness of <strong>escitalopram<\/strong>, a commonly prescribed SSRI, by disrupting serotonin levels in the brain.<\/p>\n\n\n\n<p>This insight highlights why many individuals may not respond to standard treatments\u2014and how understanding your <strong>unique genetic profile<\/strong> with CircleDNA\u2019s Mental Health &amp; Personality Test can be a vital step in your treatment journey.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The Science: Inflammation, Histamine and SSRIs<\/strong><\/h3>\n\n\n\n<p><strong>Escitalopram<\/strong>, like other SSRIs, works by increasing <strong>serotonin<\/strong>, a neurotransmitter essential for mood regulation. But in individuals with <strong>high inflammation<\/strong>, this process is compromised. The culprit? <strong>Histamine<\/strong>\u2014a chemical released during immune responses.<\/p>\n\n\n\n<p>The study found that when inflammation rises, so does histamine in the brain. This activates <strong>H3 receptors<\/strong>, which suppress serotonin release. On top of that, escitalopram inadvertently <strong>slows histamine clearance<\/strong>, further compounding the issue.<\/p>\n\n\n\n<p>\ud83e\udde0 <em>Curious about your genetic risk of poor serotonin activity or heightened inflammation?
