Introduction: Tinnitus is a medical symptom describing acoustic perceptions in the ear or in the head not related to environmental stimulation. The tinnitus is a symptom that can become a serious matter, where it can affect the functional lifestyle and psychological. Electrophysiology test: P300 Response is used as the objective measurement to evaluate neurocognitive status (attention and discrimination) among tinnitus patients. Objective: This study was performed to evaluate the neurocognitive status among tinnitus patients. Design: This is a cross-sectional and prospective study. Materials and Methods: A study of 18 subjects that divided into two groups of (1) 9 control subjects (normal) and (2) 9 experimental subjects (tinnitus); 9 experimental subjects are randomly recruited from vertigo and tinnitus clinic from ORL-HNS clinics, Hospital Universiti Sains Malaysia (HUSM). Objective measurement was performed on them to find whether there are significant differences between those two groups. The equipments used are Otoscope, Audiometer, Sony Sound Forge Pro 10.0, Speaker, Tympanometry and P300 Response (Bio-logic Navigator Pro Auditory Evoked Potentials (AEP). Result: There is significant difference in the latency of P300 response between control subjects and experimental subjects. Tinnitus patients showed neurocognitive impairment with a prolonged latency of P300 response. Conclusion: This study provides a clear picture on understanding tinnitus patients in much deeper in neurocognitive aspects and will improve the further management of tinnitus patients.
