ABSTRACT
OBJECTIVE: To determine the prevalence of anxiety and its correlation with the quality of life among cognitively-intact, community dwelling Filipino patients with idiopathic Parkinson disease (PD) seen at the Movement Disorders Clinic of a tertiary hospital.STUDY DESIGN: Prospective, cross-sectional study. METHODS: Seventy six (76) Filipino outpatients fulfilling the United Kingdom Parkinson Disease Society Brain Bank Clinical Diagnostic Criteria for PD were included in the study. Demographic data were obtained including: age, sex, onset of disease, disease duration and medication intake. The Mini Mental State Examination (MMSE) was done to exclude significant cognitive impairment. The Hamilton Anxiety scale (HAM-A) was administered to quantify anxiety. The degree of anxiety was correlated with the quality of life instrument, Short form health survey (SF 36); and the functional and motor severity using the Unified Parkinson Disease Rating Scales (UPDRS).FINDINGS: Our cohort of patients had a mean: age of 61 years (range: 42 - 81 years), and disease duration of 1.3 years (33 months). Out of the 76 patients, 37( 48.6%) probably had significant anxiety symptoms based on the the HAM A. Anxiety greatly impacts scores on SF 36.CONCLUSION: The prevalence of anxiety among this Filipino cohort of patients is 48.6% which is higher than commonly reported worldwide. The presence of anxiety significantly correlated with poorer quality of life.
