Here, we show that 40.68 MHz ultrashort wave (USW) rapidly enhances glymphatic bulk flow in healthy mice within 10 minutes. USW potentiates both glymphatic influx and efflux, concomitant with increased Delta wave neuronal synchronization, as confirmed by local field potentials and electroencephalograms. Chemogenetic silencing confirms that USW-driven glymphatic enhancement depends on neuronal activity, while pharmacological blockade of aquaporin-4 (AQP4) abolishes the effects, revealing dual reliance on neural dynamics and astrocytic water channels. Mechanistically, USW-induced Delta oscillations promote AQP4 polarization, coupling synchronized firing to perivascular AQP4 redistribution. Moreover, USW ameliorates traumatic brain injury\u2013induced cerebral edema and improves cognitive deficits in Alzheimer\u2019s mice by restoring glymphatic function. Our findings establish USW as a non-invasive neuromodulatory strategy for enhancing glymphatic clearance, offering therapeutic potential for neurological disorders characterized by glymphatic dysfunction.<\/jats:p>","DOI":"10.1126\/sciadv.aeh8870","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T17:58:53Z","timestamp":1792173533000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":0,"title":["Noninvasive ultrashort wave neuromodulation enhances glymphatic clearance to alleviate traumatic brain edema and Alzheimer\u2019s pathology"],"prefix":"10.1126","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-9758-3808","authenticated-orcid":true,"given":"Jinwei","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Medicine, The Second Medical Center &amp;
