Work with @MathiasJucker showing neurofilment light chain (NfL) in both CSF and blood are early markers of neurodegeneration, but diverge in symptomatic (autosomal dominant) AD patients -> CSF NfL may be better for monitoring outcomes in symptomatic AD doi.org/10.1038/s41467-024-5…

Excited to share our recent paper! We use genetics, bioinformatics, and cell-based studies to determine whether variants of unknown significance act as pathogenic variants to cause autosomal dominant Alzheimer’s disease @alzassociation @WashUMedADRC sciencedirect.com/science/ar…

Beautiful work by Liu et al. highlighting the importance of heterogeneity in amyloid-beta pathology, especially in the era of amyloid targeting therapies. I remember seeing this work at ADPD and am excited to see it published! @ElzHead @M_B_Miller jamanetwork.com/journals/jam…

Our latest study out today! Findings reveal PSEN2 variants with known PSEN1 homolog variant show abnormal Aβ production patterns strongly correlated with age at symptom onset, while non-homologous PSEN2 variants often exhibit wild-type-like Aβ ratios doi.org/10.1002/alz.14339

Having started my career in basic neuroscience research, I have always understood Alzheimer disease to mean the pathophysiology associated with amyloid plaques and tau tangles. As a clinician, I appreciate that the relationship between Alzheimer disease and cognitive impairment is complex. 1. Clinically diagnosing the cause of cognitive impairment is different than diagnosing that the patient has Alzheimer disease (pathology). Many of my patients with cognitive impairment have multiple diagnoses (e.g., sleep apnea, medication-related cognitive dysfunction, depression, previous cerebral infarction), and sometimes have Alzheimer disease (based on biomarker testing). I do what I can to mitigate the effects of all of these conditions, and when Alzheimer disease is present I do not assume that it is the sole or even the primary cause of cognitive impairment. This is true across multiple potential etiologies: for example, I may diagnose someone with cerebrovascular disease and a prior infarct based on MRI findings, but determine that this condition is asymptomatic and not contributing to their cognitive impairment. 2. Given the simplicity of some biomarker tests and the difficulty of clinical assessment, there is a risk that clinicians may diagnose the etiology of cognitive impairment as Alzheimer disease without doing a full work-up. This is why appropriate use recommendations for biomarkers always mandate that biomarker results must be integrated with a clinical evaluation and not used as a “stand-alone.” 3. Alzheimer disease pathology accumulates silently for ~10-20 years before the onset of cognitive impairment. However, during this pre-clinical phase the accumulation of amyloid pathology is associated with many other biomarker changes that appear pathological (e.g., abnormal CSF synaptic biomarkers, brain atrophy, brain hypometabolism). While the brain is remarkably resilient to damage and individuals may or may not develop symptoms, the brain is sick and the pre-clinical phase is a disease state. 4. Suggesting that a disease only exists when organs are severely damaged and failing (dementia) seems counter to what we have learned in other areas of medicine. For example, patients diagnosed with hypertension or asymptomatic coronary artery disease may change their diet and medications to avoid a heart attack. Individuals with asymptomatic chronic kidney disease may or may not go on to require dialysis, but they can be monitored and sometimes treated. 5. There are valid concerns about the stigma and risks of asymptomatic individuals being labeled as having Alzheimer disease given that they may or may not develop cognitive impairment. The solution is simple—we don’t perform biomarker testing in asymptomatic individuals outside of research studies or clinical trials. Again, this has been mandated by appropriate use recommendations for biomarkers. We can help patients by promoting accurate understanding and appropriate use of biomarkers. #EndAlz
