Introduction: Sleep and headache problems are among the significant concern of health sector. But the exact relationship between these two important has been studied less. Therefore this study is designed to determine the relationship between sleep quality and primary headache .Sleep and headache share a well-recognized, bidirectional relationship, with complex and incompletely understood interactions. The physiology of sleep shares many features with the pathophysiology of headache disorders, both in terms of the neuroanatomical pathways and the neurotransmitters that are involved. This may explain features of primary headache disorders like migraine, cluster headache and tension type headache. Moreover, the painful experience of headache itself disrupts sleep, potentially creating a vicious circle of reinforcement. Both sleep disturbance and chronic headache also greatly increase the risk of depression, anxiety and other psychiatry disturbances hence further affecting the complex relationship between sleep and headache. Methods: Present sample consists of 60 patients who presented with the complaints of primary headache to the department of psychiatry and neuropsychiatry clinic in a tertiary care institute from August 2016 to June 2018. This is a cross sectional Observational study. After being evaluated by the neuropsychiatry clinic, the patients along with records of treatment and classification of primary headache will be evaluated for sleep quality. A self-administered questionnaire Pittsburgh Sleep Quality Index (PSQI) that assesses sleep quality over a 1-month time interval was used to collect data. Result: Headache occurance is associated with poor sleep quality .In this study 95% of the patients presenting with headache had association with poor sleep quality. Conclusion: In this study, there is well established relationship between sleep quality and headache has been shown but more and similar evaluation and study are needed to complete and confirm this relationship in future.
