Can Ramadan fasting cause relapse and aggravation of spontaneous intracranial hypotension?

Chronic headache is known to be aggravated by fasting and fasting even triggers headache among those not suffering from chronic headache. Headache is also aggravated during Ramadan in which Muslim people do not eat, drink, or smoke from dawn to sunset for about one month in a year. Headaches mainly increase in people who are prone to headaches like migraine sufferers.

Anastomoses of the vestibular, cochlear, and facial nerves.

The internal auditory canal (IAC) is 10 to 17 mm in length, and the facial nerve and vestibulocochlear nerve, which consist of the cochlear nerve, the superior vestibular nerve, and the inferior vestibular nerve, run together in the IAC packaged in dura mater. Oort first described the vestibulocochlear anastomoses in 1918, which is important for the understanding of the pathogenesis and pathophysiology of otologic disorders. The current study documents the existence of vestibulofacial and vestibulocochlear neural connections and topographical relationship of the nerves as part of a radiologic evaluation of 73 human temporal bones from brainstem to the lateral portion of IAC.

A Radiological Study on the Topographical Relationships between the Vestibular, Cochlear and Facial Nerves.

Objective: The purpose of our study was to investigate the topographical relationship between these nerves along their course from the brainstem through the internal acoustic canal IAC in the living human brain using MR imaging.

Materials And Methods: We performed three-dimensional gradient echo balanced Fast Field Echo (3D bFFE) sequence oblique parasagittal MR imaging in 73 healthy subjects. The IACs were analyzed from the brainstem end of the IAC to the fundus in contiguous sections.
