So hard to keep colleagues, patients and the Alzheimer’s charities focussed on what the trial data actually show rather than what we’d all want to believe the drugs might be able to do.
Misleading to claim #donanemab or any amyloid lowering Rx will allow an #Alzheimer’s patient to continue to drive independently. Inserting the claim immediately outside a respected KOL’s quote also risks wrongly attributing this to them. Not a good look @ProfRobHoward @pash22

Happy to share our paper on atrophy heterogeneity in memory clinic settings – now online @Brain1878! This was a big one (started working on this on the first day of my PhD 👀), so let me walk you through it 🧵 [1/n] tinyurl.com/subtypesNstages @DZNE_en @biofinder_study @david_berron
@smead2 @VincentPlanche @TharickAPascoal @erzimmer @psanjua @zimmerneurolab @limberger_chris @Brain1878 There's no need to waste time on that: we're all very busy. I just enjoy chatting with you all on Twitter and asking questions to better understand "our" diseases
@TharickAPascoal @erzimmer @psanjua @zimmerneurolab @limberger_chris @Brain1878 What level of evidence are we discussing regarding the validation of blood GFAP? Mentioning other biomarkers is irrelevant to my current concern on GFAP (we still don't have good TDP43 biomarker but that's not a reason for making any lousy biomarker the new gold standard)
@erzimmer @psanjua @zimmerneurolab @limberger_chris @Brain1878 Thank you very much, Eduardo! Much appreciated! So, in short, do you agree that classifying Ast-/Ast+ based on serum GFAP would be incorrect from a biological point of view?

Thal and neuropath, generally speaking, only consider neuritic plaques, not diffuse plaques... Therefore, saying that A+ (all its dimensions) =AD is going too far: beyond what any nosologist (neuropath or clinician) has ever dared to go

The logic of the new criteria has a floating definition of AD based on biomarker detection threshold of the “earliest possible pathophysiology”, by which they mean the amyloid pathway. Core 1 marks low to intermediate neuropath. So that’s AD for now.
@DavidJonesBrain @smead2 @MadhavThambiset @SuzanneESchind1 @DrTFromKC @seb_walsh @pash22 @EWidera @ajlees @ProfRobHoward @MemoryDoc @dr_shibley @LonSchneiderMD @_michael_scholl @VincentPlanche @StefanoSensi14 @AlbertoEspay @KasperKepp @PhilAlz @Gill_Livingston @jfballenger @jasonkarlawish @JamesRuFletcher @AdamMBrickman @ManlyEpic @SFAckley @FortuneMagazine @TIME @ErinMPrater @TIMEMagazineRS @FT @hannahkuchler @CTADconference @NIH @alzassociation @howard_gleckman @AmerGeriatrics @kathy_y_liu @r_merrick @nlundebjerg @NathanielChinMD @US_FDA @NICEComms @RaymondKoopmans @MaastrichtU @Kariem_Ezzat @DrBenUnderwood1 @NHSEngland @ObserverUK Absolutely! Biomarker sensitivity limits access to earliest stages. However, as you say, the theory is "Our position is that the onset of β-amyloidosis defines the initially detectable stage of AD" Improved biomarker sensitivity will enable diagnosing Thal Phase 0a in the future

If negative, this would be highly useful, of course.
