T188, 2026-08-31, from Jesse's own screenshot of\n   \/scan-hersteltest\/ on a 375px iPhone: the H1 compound \"ontstekingswaarden\"\n   ran off the screen and was cut mid-word.\n\n   The cause, measured rather than guessed, and it is NOT the rule above. The\n   GRID TRACK was the right size all along: at 375 the hero grid measured 335,\n   exactly the section's content box. What overflowed was the grid ITEM. A grid\n   item's default `min-width: auto` gives it an automatic minimum size equal to\n   its min-content width, and the min-content of the hero's head column is the\n   widest unbreakable word in the H1: `ontstekingswaarden` needs 365px at 34px\n   Poppins Bold. So the item laid out 359 wide inside a 335 track and hung 24px\n   out of it, and by 375 the last of that had crossed the screen, where the body\n   clipped it.\n\n   `overflow-wrap: break-word`, declared on that H1 one line above, cannot help\n   and this is the whole trap: by spec it introduces a soft-wrap opportunity for\n   LINE LAYOUT only, never for INTRINSIC sizing. So it never reduced the item's\n   automatic minimum, and inside the oversized item the word then fitted on a\n   line and had no reason to break.\n\n   Measured on the unfixed build at 320 and 375, one rule injected at a time:\n   `min-width: 0`, `hyphens: auto` and `minmax(0, 1fr)` each take the head column\n   back to the track width on their own. Every DESKTOP grid in this sheet already\n   carries `minmax(0, ...)`; the mobile collapse rules had dropped it, which is\n   the reason the fault only ever showed on a phone.\n\n   Two rules therefore, and they do different jobs:\n\n   1. `min-width: 0` on the block containers that are grid or flex items, so an\n      item can never hand a track a minimum bigger than the space there is. This\n      is the guard that makes the class of fault impossible rather than fixing\n      one instance of it. Named containers only, never every div: `min-width: 0`\n      on a flex chip would let it collapse.\n   2. `hyphens: auto` on headings, so that when a Dutch compound still has to\n      break it breaks at a legal syllable with a hyphen instead of snapping\n      mid-morpheme. The article is inside `<html lang=\"nl-NL\">`, which is what\n      the hyphenation dictionary keys off; this is the same remedy the four\n      column band label already uses further down. *\/\n.bp-scan .bp-scan-hero2 > *, .bp-scan .bp-scan-hero-head,\n.bp-scan .bp-scan-split > *, .bp-scan .bp-scan-cols > *,\n.bp-scan .bp-scan-instgrid > *, .bp-scan .bp-scan-scale > *,\n.bp-scan .bp-scan-verify > *, .bp-scan .bp-scan-author > *,\n.bp-scan .bp-scan-links > * { min-width: 0; }\n.bp-scan h1, .bp-scan h2, .bp-scan h3 { -webkit-hyphens: auto; hyphens: auto; }\n\n\/* WordPress core's flow-layout stylesheet gives every child after the first a\n   24px block-start margin. Inside a normal column that is spacing; inside a grid\n   or a flex row it is a misalignment. Measured on the live page 2026-08-21:\n   band cards two and three sat 24px lower than card one AND lost 24px of their\n   stretched height, so the row read as broken. Zeroing it on the row containers\n   is the fix; core's rule is written with :where() so it carries no specificity\n   and a plain class selector wins. *\/\n.bp-scan .bp-scan-scale > *, .bp-scan .bp-scan-links > *,\n.bp-scan .bp-scan-facts > *, .bp-scan .bp-scan-verify > *,\n.bp-scan .bp-scan-instgrid > * { margin-block: 0; }\n\n\/* the page opens on brand colour, never on grey *\/\n.bp-scan .bp-scan-rule {\n  height: 6px; border: 0; margin-block: 0; max-width: none;\n  background: linear-gradient(90deg, #005859 0%, #006B62 38%, #228A62 66%, #B7CB33 100%);\n}\n\n\/* --- section surfaces.

You walk into the room and have lost what you came for. Following a conversation takes effort, making a decision takes more, and by three in the afternoon your head is a radio between two stations. You are not ill. Your head is just not joining in.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The awkward thing about brain fog is that no measurement for it exists. There is no thermometer for your head, and usually no test at your GP either, so it stays a word you chose yourself for something you feel yourself. Researchers who did try to capture it kept arriving at the same list: slow thinking, trouble concentrating, confusion, forgetfulness, a haze over your thoughts. Recognisable, and still not a number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What you can do is measure the pattern instead of the feeling: how often the fog is there, how well you hold your attention, how often you forget everyday things, and how much effort thinking costs you. Four questions about two weeks, added up into a score from 0 to 100. Not a diagnosis. But a number. And in two weeks you can lay that number next to a new one.<\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-scan-split-media is-layout-flow wp-block-group-is-layout-flow\">\n\n<div class=\"wp-block-group bp-scan-shot bp-scan-shot--mid is-layout-flow wp-block-group-is-layout-flow\">\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"739\" height=\"1024\" src=\"https:\/\/bioprofile.com\/wp-content\/uploads\/2026\/08\/bp-scan-hersenmisttest-vraag-37c56950-739x1024.webp\" alt=\"The first two questions of the BioProfile brain scan, about mental fog and holding your focus, each with five answer options\" class=\"wp-image-5071\" srcset=\"https:\/\/bioprofile.com\/wp-content\/uploads\/2026\/08\/bp-scan-hersenmisttest-vraag-37c56950-739x1024.webp 739w, https:\/\/bioprofile.com\/wp-content\/uploads\/2026\/08\/bp-scan-hersenmisttest-vraag-37c56950-217x300.webp 217w, https:\/\/bioprofile.com\/wp-content\/uploads\/2026\/08\/bp-scan-hersenmisttest-vraag-37c56950-768x1064.webp 768w, https:\/\/bioprofile.com\/wp-content\/uploads\/2026\/08\/bp-scan-hersenmisttest-vraag-37c56950-1109x1536.webp 1109w, https:\/\/bioprofile.com\/wp-content\/uploads\/2026\/08\/bp-scan-hersenmisttest-vraag-37c56950.webp 1360w\" sizes=\"(max-width: 739px) 100vw, 739px\" \/><figcaption class=\"wp-element-caption\">Questions 1 and 2 of 4.

You have not recorded anywhere how foggy it was when you started, and with your own thinking your memory is a poor witness: you remember a clear day, a foggy week fades.

Self-reported complaints about memory and concentration are linked more strongly to mood and fatigue than to ability, and read the other way round that is exactly what makes it useful: a low score usually points to sleep, stress or mood, and those you can do something about.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">7<\/a><\/sup> That is why this number is called a focus score, and not a test.<\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-scan-sci is-layout-flow wp-block-group-is-layout-flow\">\n\n<h3 class=\"wp-block-heading\">Why these four in particular<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In 2008 Mitchell lined up the studies in which people were asked about their memory: among people in whom cognitive decline had been established, 39.8 per cent reported complaints, against 17.4 per cent of healthy older people, more than twice as often.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">8<\/a><\/sup> In 2014 Jessen and an international working group set down how research into self-experienced decline ought to be carried out, precisely because that experience is sometimes there before a test sees anything.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">9<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our four questions follow what that research asks about: the fog itself, your attention, your everyday memory and the effort thinking costs you. We worded them ourselves, after no licensed instrument, and the cards above say so in so many words.<\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-scan-sci is-layout-flow wp-block-group-is-layout-flow\">\n\n<h3 class=\"wp-block-heading\">What a low score means, and above all what it does not mean<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In 2010 Lim and Dinges pooled seventy studies with 147 cognitive tests on what one night without sleep does: the largest effect was in attention slipping away, with an effect size of 0.78, the smallest in reasoning.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">10<\/a><\/sup> Van Dongen and colleagues had 48 healthy adults sleep 4, 6 or 8 hours for two weeks: at 6 hours or less the deficits in thinking performance stacked up day after day, to the level of two nights of no sleep at all, while the participants themselves said they were barely any sleepier.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">11<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lo and colleagues found in 2016, across 35 samples and more than 97,000 older people, that both short and long sleep raised the chance of poorer thinking, by 1.40 and 1.58 times.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">12<\/a><\/sup> Rock and colleagues found in 2014, in people with symptoms of low mood, moderate shortfalls in executive functions, memory and attention, with effect sizes of 0.34 to 0.65, and part of that remained after the mood recovered.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">13<\/a><\/sup> Shields and colleagues showed in a meta-analysis in 2016 that acute stress too harms working memory and mental flexibility.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">14<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why this score is never read on its own: a low focus score is usually a sleep, stress or mood score in disguise. And a sudden, clear change in memory or language is not a score to follow, but a reason to see a doctor. Only a doctor can make a diagnosis.<\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-scan-sci is-layout-flow wp-block-group-is-layout-flow\">\n\n<h3 class=\"wp-block-heading\">Why your head is worth measuring<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In 2010 Killingsworth and Gilbert had people report through the day, via a smartphone app, where their thoughts were: almost as often on something other than what they were doing, and that wandering generally left them less happy.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">15<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In 2018 Northey and colleagues pooled 39 randomised studies in people over fifty: exercise improved thinking ability with an effect size of 0.29, whatever cognitive level someone started from, and sessions of 45 to 60 minutes at moderate intensity or above went together with the greatest benefit.\u2060<sup class=\"bp-scan-sup\"><a href=\"#bronnen\">16<\/a><\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is correlation and effect from research and it promises nothing about your head. What it does say: perceived thinking moves along with sleep, stress and exercise, and what moves along can be followed.<\/p>\n\n<\/div>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-scan-bridge bp-scan-bridge--row is-layout-flow wp-block-group-is-layout-flow\">\n\n<div class=\"wp-block-group bp-scan-bridge-text is-layout-flow wp-block-group-is-layout-flow\">\n\n<p class=\"bp-scan-bridgelead wp-block-paragraph\">This is what the scan rests on.
