Case Report: Barely Able to Speak, Can’t Stop Echoing: Echolalic Dynamic Aphasia in Progressive Supranuclear Palsy

Frontiers in Aging Neuroscience, 2021
The diagnostic criteria for progressive supranuclear palsy (PSP) incorporate two speech-language disturbances (SLDs), non-fluent/agrammatic primary progressive aphasia and progressive apraxia of speech, but overlook the inclusion of other SLDs, including

Morphological and Hyperphosphorylation Transitions of Nanoscale Tau Aggregates in Alzheimer's Disease

Advanced Science, EarlyView.
Super‐resolution microscopy identifies nano‐sized tau aggregates (nano‐aggregates) and reveals distinct transitions in their morphology and phosphorylation profiles across control, Primary Age‐Related Tauopathy, and Alzheimer's disease brains. Morphology and hyperphosphorylation signatures distinguish physiological from pathological forms, with nano ...
