Researchers will compare the results obtained from olfactory stimulation with those from somatosensory and auditory stimulations to determine whether the olfactory method provides additional or superior prognostic value.\n\nParticipants will receive additional olfactory stimuli as part of the neurophysiological evaluation for prognostic purposes and be followed up at 3 months for clinical, neurological, and functional evaluation",[69],"Disorders of Consciousness Due to Severe Brain Injury","2025-08-11",{"date":72,"type":73},"2025-08-17","ACTUAL",{"date":75,"type":73},"2024-02-05",{"date":77,"type":63},"2027-05-05",{"name":5,"class":6},1]
