I. Introduction
Asymmetry of the lateral brain ventricles is a typical finding in a CT scan imaging of the normal brain with an incomprehensible etiology (Grosman et al, 1990). The formation of asymmetry lateral brain ventricles is an estimated pathological outcome in the arrangement of the lesion occupying the space, intracranial bleeding, trauma, as well as recent infarction (Kiroglu et al, 2008). On the contrary, the discovery of the asymmetry without apparent causes on CT imaging can develop an unexplainable and intriguing finding. According to Kiroglu et al (2008), despite the fact that asymmetrical lateral ventricle is a typical occurrence having no clear pathologic ground, a number of correlates have been studied including the individuals` right or left-handedness, functional weakness and age. Nonetheless, the mechanism the results to this asymmetry continue to be conjectural, and the restrictions of acceptable symmetry have not been developed.
The main purpose of this study is to investigate the relevance of asymmetrical lateral brain ventricles in the occurrence of migraines and headaches.
II. Review of Specific Concepts
According to Valencia et al (2002), in a retrospective study conducted by the group, a computed tomography was used in 78 patients with tension-type headache and migraine, and found that the CT scan result was normal while abnormalities such as inflammatory sinus disease, unruptured cerebral aneurysm, cysticercosis, basilar impression, arachnoid cyst, intracranial lipoma, empty sella, and intracranial neoplasm were seen in 30% of the patients. In patients with frontotemporal dementia, asymmetry in the lateral brain ventricle on neuroimaging is believed to have clinical significance (Grosman et al, 1990). Nineteen patients with dementia were given an MRI and the results showed high correlation which means that dementia, a disease which presents a symptom of headache and vomiting, is associated with asymmetry in the lateral brain ventricles.
III. Integration of concepts
Headaches and migraines are attributed to cerebral problems particularly when the cerebrospinal fluid shunts particularly in hydrocephalus cases (Nowak and James, 1989). In some studies brain diseases or illnesses that present symptoms of headaches have been found to affect the lateral brain ventricle. However, there are still a number of studies that postulates no correlation between the two variables – asymmetrical lateral brain ventricles and headaches or migraine.
IV. Rationale for Study and Design
With this study I intend to gather information to correlate the presence of slight to moderate asymmetric lateral brain ventricles, otherwise known to be a non-specific finding, to that of patients with chronic headaches or migraines. I intend to conduct this study with retro research over one quarter of a year on a target populous of patients who had undergone head CT scans with a clinical indication of chronic headaches or migraines at a particular medical facility. While conducting this research I am expecting to have a greater number of headache patients to have asymmetrical lateral ventricles than normal ventricles. The lateral ventricles of the brain contain the cerebrospinal fluid which when the latter shunts, headaches or migraines transpire.
V. Overview and Niche for the Study
The ventricular system of the brain serves as a continuation of the spinal cord central canal. The ventricles contain the cerebrospinal fluid which tends to increase in volume as the individual reaches old age. When headache starts to present, a CT scan and MRI can be used to get a view of the ventricles and examine the quantity of the CSF. When there is asymmetry, headache occurs which eventually, when not given immediate medical attention, can lead to worse brain conditions such as dementia, Parkinson`s disease, and multiple sclerosis.
