The vestibular system works as a reference system to other systems such as visual and somatosensory, but when there is commitmen of the same, individuals have dizziness, imbalance, gait abnormalities, which often can lead to falls. Additionally, some studies have suggested the presence of cognitive dysfunction in these patients. Objective: To evaluate the correlation between dizziness, cognitive, balance semi-static and dynamic in patients with chronic dizziness of vestibular origin. Methods: This is a study of observational and descriptive. Cognitive assessments will be carried out, which include the Mini Mental State Examination (MMSE; only for screening and inclusion criteria), the clock drawing test (TR), verbal fluency (VF) and Trail making B and will be analyzed variables limit, Modified Clinical Test of Sensory Integration in Balance (CTSIB), sitting and standing and gait using the Balance Master equipment. The dizziness will be assessed by the Dizziness Handicap Inventory (DHI).Will be held the normality test of Shapiro-Wilk, for verification of normal distribution of data, which justify choosing the best test for the analysis of statistical inference. Correlation tests will be conducted between the variables of cognitive (Memm, FV, TR and TMB) and functional body balance (stability limit, TCTSIB, Sit and stand up and march) from Balance Master, in which tests may be used Pearson or Spearman correlation as distribution of data normality. Expected results: Expected to find a correlation between cognitive impairment and deficits in balance and gait in individuals with chronic dizziness arising from vestibular dysfunction, and higher cognitive impairment, higher functional impairment.
