Neurodegeneration’s systemic roots: How colonial science ignored Indigenous sleep rhythms and stress responses—now Western labs scramble to replicate ancient wisdom
Original framing: “Can we harness the brain’s deep-cleaning system to prevent Alzheimer’s?” — New Scientist
Marginalized voices—particularly those of elderly women of color, who bear the highest Alzheimer’s risk—are absent from glymphatic research. For example, Black women in the U.S. are 64% more likely to develop dementia, yet studies rarely examine how systemic racism (e.g., limited healthcare access, environmental toxins like lead in Flint) disrupts glymphatic function. Migrant farmworkers in California, whose sleep is fragmented by piece-rate labor, report 'brain fog' decades before retirement age, but their testimonies are excluded from clinical trials. The framing of glymphatic 'boosting' as a personal choice ignores how structural violence (e.g., redlining, prison industrial complex) already suppresses these systems. The trickster here is the individualization of neurodegeneration—blaming 'lifestyle' while ignoring the lead pipes, polluted air, and food deserts that erode brain health at scale.
The glymphatic system’s sensationalized framing obscures a far darker story: the violent erasure of Indigenous and traditional knowledge that once sustained brain health at scale, now repackaged as 'innovation' by industries profiting from the very crises they helped create.
Colonial science’s pattern of suppression and repurposing—seen from 'hysteria' to 'race science'—repeats here, where communal practices become individualistic 'hacks' and ecological wisdom is reduced to biochemical pathways. The solution isn’t to 'harness' the glymphatic system but to dismantle the systems that destroyed its natural conditions: from lead-laced water to algorithmic sleep policing. What’s needed is a **glymphatic sovereignty movement**—one that reclaims brain health as a collective right, not a consumer product, and forces a reckoning with who gets to define what’s 'natural,' 'scientific,' or 'human.' The trickster’s lesson? The brain’s deep-cleaning system was never just about flushing toxins—it was about flushing out the lies of power, too.
