Genetic Anticipation of Huntington's Disease
Why does the HTT CAG repeat expand across generations, and why almost always through the father? The case for a repair-driven, not replication-driven, mechanism.

Parkinson's Disease Is to Lewy Body Disease as Alzheimer's Disease Is to Frontotemporal Dementia
The analogy is tempting — a signature protein anchoring a whole disease family in both cases — but only one side of it is actually a subset relationship.

Parkinson's and the Chemicals of the West
Parkinson's tracks industrialization too closely to be coincidence. Pesticides, solvents, and air pollution all converge on the same loaded gun: the dopamine neuron.

The Curious Case of ARPdV
A Colombian woman carried a mutation that should have caused Alzheimer's in her 40s and a genetic quirk that kept her lucid into her 70s — what her brain reveals about where amyloid stops and neurodegeneration begins.

Biomarkers of Alzheimer's Disease
A survey of amyloid, tau, CSF, PET, and blood-based biomarkers for Alzheimer's — and why they're better at ruling pathology in than at predicting exactly when it will strike.

Hypoxia-Ischemia, Seizures, and Hypoglycemia
Three very different neurological insults converge on the same excitotoxic pathway to necrotic neuron death, but they don't damage the same parts of the brain.
