Ayurveda gives further importance to the causative factors of the disease, as it eliminates the disease from the root cause. Vyadhi vinischaya according to Ayurveda consists primarily of Rogapariksha and Rogipariksha, it gives detailed knowledge about the disease starting from the etiological aspects to the actual manifestation of the disease. The five basic components of Rogapariksha are Nidana, Purvarupa, Rupa, Samprapti, and Upashaya, which are collectively known as Nidana Panchakas. Nidana, the foremost element among them not only gives the knowledge of causative factors but also helps in treatment by avoiding them. “ Shiraso Uttamangatvam1”, Shiras is considered as Prime organ, and also its one among trimarmas, thus special care and concern should be taken to protect it. Ardhavabhedaka, one of the shiroroga mentioned by our Acharyas. In contemporary science, it can be related to Migraine. In Samhitas, they mentioned Treatment modalities like Shirovirechana, Nasya Karma, Shamana chikitsa, Siravyadha, Shirodhara, Shirolepa, Agnikarma, for Ardhavabhedaka. However, it leads to diseases like deafness and blindness2, if left untreated. Hence early detection and intervention are necessary for Ardhavabhedaka. Thus an attempt is made to analyze the nidana and Chikitsa of Ardhavabhedaka.
