dc.description.abstract Migraine - with or without aura - is an enervating primary headache disorder that represents a heavy economic and social burden. The health-related quality of life of migraineurs is poor. The aim of this research was to investigate the health-related quality of life of migraine without aura sufferers. As the thesis was approached from a biopsychosocial perspective, potential determinants were chosen for investigation from the molecular, individual, interpersonal and wider societal levels. The research was executed in two phases: Phase 1 data (N = 341) were gathered using a survey of health-related quality of life (Short Form 6), temperament (the Tridimensional Personality Questionnaire), catastrophizing as a pain coping strategy (the four-item Pain Coping Scale) and the amount of perceived social support (the six-item Social Support Questionnaire). For phase 2, participants were requested to provide blood specimens for ELISA serum quantification of glutamate (n = 66) and gene expression analysis of the main glutamate transporter gene SLC1A2 on real-time reverse-transcription polymerase chain reaction (n = 20). Of the 341 adult residents of Gauteng Province, South Africa that participated in the survey, 94 (28%) met the criteria for migraine without aura and a further 60 (18%) suffer from possible migraine without aura, using the International Classification of Headache Diagnosis (2nd edition) criteria. This indicates that migraine without aura is a significant burden for South Africa. Health-related quality of life was significantly poorer for migraineurs versus those without migraine (p < .001), and is in fact comparable to that of liver transplant, cardiac bypass and elderly populations. This raises concerns about the severe burden of the disease on the mental and physical well-being of South African sufferers. Investigation of the predictors of health-related quality of life yielded two significant variables when controlling for sex, head and neck injury and language - Harm Avoidance and vii Catastrophizing. The regression model accounts for 29% of the variance in health-related quality of life. A reciprocal relationship likely exists between Harm Avoidance and Catastrophizing, in which a harm avoidant migraineur interprets the headache pain as a catastrophic event to be avoided – even at high cost to the self. Though there have been calls for more biopsychosocial studies of migraine, this thesis did not find added understanding of health-related quality of life through the combination of biological and psychosocial data. The implication is that the role of glutamate in migraine without aura still requires further investigation. Further study is also required with regard to which biological factors may influence the sufferer’s quality of life. The thesis indicates a key role for psychological intervention in aiding migraineurs to live a life of quality. The inclusion of interventions for the psychological aspects of migraine may yield improved outcomes for patients. However, Gauteng residents suffering from MO are potentially unaware of their diagnosis and therefore of potential management for their disorder. Awareness around migraine needs to be the first step in limiting this disorder’s devastating impact on individuals, their relationships and their potential to contribute meaningfully to society. en
