At AD/PD Conference, New Alzheimer’s Genes Reinforce Known Pathways
After years of grunt work on next-gen sequencing and expression analysis, geneticists are finally reaping results. The new genes underscore the role of known pathways and cell types in disease.

In Football Players With Possible CTE, Tau-PET Reveals Subtle Tau Deposition
Flortaucipir in former NFL players cropped up in regions known to be affected by chronic traumatic encephalopathy, but uptake was low compared with AD. Whether this reflects low tau deposition or poor tracer binding remain to be seen.
Familial Alzheimer’s Mutations: Different Mechanisms, Same End Result
A fleet of patient-derived neurons show that while an APP mutation shifts where γ-secretase takes its first bite, PS1 mutations blunt the enzyme’s second cut. Eventually, all mutations drive up the Aβ42:40 ratio.
Closing the Book on NSAIDs for Alzheimer’s Prevention
The latest effort to determine if a non-steroidal anti-inflammatory drug protects against Alzheimer’s posted negative results. Time to abandon the approach?
Results from Verubecestat APECS Trial Published
The Phase 3 trial ended early when prodromal AD patients on the BACE1 inhibitor declined faster than those on placebo.

AD/PD Meeting in Lisbon Hosts a Humbled Field
Held in romantically beautiful Lisbon, the 14th AD/PD conference was the biggest thus far, drawing 3,982 attendees from 73 countries, according to Abraham Fisher, its longtime lead organizer. But as the field grows, it has little to celebrate, and the mood reflected that. Trialists were appealing for patience and pointing to deepening clinical trials skills as they learn from setbacks on investigational therapies, most recently of lanabecestat, crenezumab, and aducanumab. Trials targeting tau were not yet reading out, but the medical food Souvenaid posted modestly positive results. At the other end of the bench-to-bedside spectrum, basic science is diversifying. Next-gen genetics is spilling out gene variants which, together with RNAseq, are energizing research into glial and lipid biology. Debate about the amyloid hypothesis, a fixture at AD/PD, evolved toward a focus on genetic variability in how a person’s innate immune system responds to amyloid deposition. Ab itself? Nothing special about it. It aggregates into an irritant as the brain’s ability to degrade it wanes with age. It starts things off, but other factors later dominate the disease. Or so researchers now think. Read Madolyn Rogers and Gabrielle Strobel’s coverage.
Closing the Book on NSAIDs for Alzheimer’s Prevention
Ever since epidemiological studies found that people who take non-steroidal anti-inflammatory medications have lower rates of developing Alzheimer’s, researchers have tried turning this association into treatment success. It never worked. Now, in a clinical trial, the NSAID naproxen did not delay cognitive decline in people in their 60s who were at high risk of Alzheimer’s, but it did cause significant side effects. Together with past trials, the new results suggest that NSAIDs cannot prevent AD.
