TDP-43 undergoes pathological liquid-liquid phase separation in ALS/FTD, and small molecules that restore liquid-like properties could theoretically address both nuclear loss-of-function and cytoplasmic gain-of-function toxicity. However, this hypothesis faces fundamental barriers: no defined binding pocket exists for intrinsically disordered regions, distinguishing pathological from physiological LLPS remains unsolved, and no validated biomarker exists for target engagement. Precedent failure o
Antisense oligonucleotides targeting expanded GGGGCC repeats in C9orf72 offer the strongest therapeutic hypothesis by simultaneously addressing three pathogenic mechanisms: C9orf72 haploinsufficiency, RNA foci sequestration, and toxic dipeptide repeat protein accumulation. The tofersen precedent validates the ASO modality for motor neuron disease, and ongoing clinical trials (NCT03626012) provide immediate translational momentum. Critical risks include cortical delivery limitations for FTD patho
