Purpose: Headache is associated with the suspension of the peripheral and central nervous systems. It is known that in individuals who suffer from Covid-19, the complaint of swelling may be related to the peripheral and/or central nervous system’s attitude. This study aims to evaluate the effects on vestibular and oculomotor systems after Covid-19. Tools and Methods: The study included 28 individuals with Covid-19 history and 20 healthy individuals without Covid-19 history. Both groups have been subjected to the Head Invalidity Inventory, Videoistagmography (VNG) and Video Head Impulse Test (VHIT). The findings: according to the vHIT results; in the study group, the vestibulocular reflection gains (VOR) of the right lateral and left anterior semicircular channel are obtained lower compared to the control group, while the vestibulocular reflection asymmetry of the anterior and posterior semicircular channel is obtained higher (p<0.05). The smooth pursuit test gain values in the study group are achieved significantly lower than the right eye at 0.1 Hz, the left and right eye at 0.2 Hz, the left and right preferred control group at 0.4 Hz, while the accuracy values in the sakkad test are achieved less than the right eye at 0.1 Hz (p<0.05). In the optokinetic test, the earnings were lower in people with Covid-19 history (p<0.05). The result: Covid-19 may not cause a serious headache problem, but the abnormalities we observe in the objective test results suggest that this situation may have a long-term negative impact on the quality of life of individuals.
