- 2026-07-23 — Hyperviscosity encephalopathy in suspected polycythemia vera at high altitude: a case report.: Case report (mpn-direct, single case) describes acute hyperviscosity encephalopathy as the initial presentation of suspected polycythemia vera in an extreme high-altitude resident; authors emphasize that EPO measurement and JAK2 mutational analysis are required to distinguish PV from altitude-induced secondary polycythemia before attributing symptoms to altitude alone.
