Un registro objetivo en el EEG podría ayudar a distinguir cuánto de lo que se siente es daño real. Para un chico que se golpeó jugando al fútbol o una persona mayor que se cayó, la diferencia puede ser entre una recuperación bien acompañada y meses de síntomas sin explicación. Aun así, es un estudio transversal y todavía no mide qué tan útil es como herramienta diagnóstica.","quienFirma":"medRxiv (preprint; institución principal no identificada en el extracto)","confianza":"preprint","consulta":null},"sello":{"hash":"ebc1d947c5e08df9ef7b6544c187e25c80a6ecdff2eaa6f6aa691b0470327f2b","sello":"4e7197d576fd23b9ffd7ceb50432da4081ba9753617904c1249b153e83b0730c","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6580941,"aleatorio":"569a6d14a17bcc63dfb56728ed9891ce2f6d709c28f85f634a2a00169794082e","tiempo":"2026-10-24T16:27:30.000Z"},"nist":{"cadena":2,"pulso":1997664,"salida":"1DC1537A6019D5A1F1814580669DA98F771591D482822D2AE01E16CD05DDDA04CB23793AAC36D0627B9ED52DE5568FC5EFA7F21FCC50B397FA952CA4E4ECDF10","tiempo":"2026-10-24T16:27:00.000Z"},"noAntes":"2026-10-24T16:27:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 24 16:28:01 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Age and sex impact resting-state EEG aperiodic activity beyond symptom associations in persistent post-concussive symptoms","descripcion":"Objective: to investigate whether resting-state EEG aperiodic parameters (i.e., offset and exponent) are associated with symptom burden and demographic factors in patients with persistent post-concussive symptoms (PPCS) and differ from healthy controls. Methods: In this cross-sectional observational study, resting-state eye-closed high-density EEG was recorded in patients with PPCS and in age-matched healthy controls. Aperiodic parameters were extracted from EEG power spectra. In patients, hierarchical multiple linear regression models included age and sex as a base model, with additional demographic and clinical symptoms entered separately.
