A Systematic Review of Vertigo: Negligence in Pregnancy

From conception to childbirth, there are many physical, hormonal, and psychological changes that a woman undergoes during pregnancy. During this time, balance is also affected, resulting in symptoms like vertigo and unsteadiness. These symptoms can lead to physical impairment and disability and can develop at any time. Vertigo in pregnancy has not been extensively written about. The subject of a narrative review is vertigo in pregnant patients. In pregnant women, hormonal alterations in the peripheral tissues and inner ear organs may contribute to vertigo. Meniere's disease, mild convulsive positional dizziness, and oculomotor migraines are all commonly exacerbated by pregnancy. Between the second and third trimesters of pregnancy, specific modifications to proprioception and hearing are also detected during physical examination. Patients who are pregnant typically experience these symptoms throughout this time. Some vertigo conditions can worsen during pregnancy, while others can appear at any time. Understanding audio-vestibular symptoms' pathological and clinical relationship during pregnancy requires more study.

Vertigo in Pregnancy: A Narrative Review

During pregnancy, physical, hormonal, and psychological changes may occur from conception to labor. Balance is also impacted throughout this time, leading to symptoms such as vertigo and unsteadiness. These symptoms may appear at any time and can cause disability and physical impairment. Little has been published about vertigo in pregnancy. We performed a narrative review of vertigo in pregnant patients. Vertigo in pregnant females may be associated with hormonal changes in peripheral structures and inner ear organs. Meniere’s disease, vestibular migraine, and benign paroxysmal positional vertigo are usually exacerbated during pregnancy. Specific changes to hearing and proprioception in the physical examination are also noted between the second and third trimester of pregnancy. These symptoms are usually seen in pregnant patients throughout this time. Some types of vertigo may be exacerbated and others may present at any time of pregnancy. Further research is needed to understand the clinical and pathological association of audiovestibular symptoms during pregnancy.

Absence of mRNA encoding estrogen receptor in the rat cochlea

Based on changes in hearing thresholds and tinnitus that are co-related with the menstrual cycle, it has been suggested that the cochlea may respond directly to estrogen. For this to occur, the cochlea should express estrogen receptors. In situ mRNA hybridization was performed on normal female rat cochleas, using radiolabeled RNA probes complementary to mRNA encoding estrogen receptor, to determine whether estrogen receptors are present in the cochlea. Strong hybridization of the riboprobes to sections of uterus and hypothalamus indicated that the technique detected estrogen receptor mRNA. No hybridization to any cochlear tissues was observed. The results indicate that estrogen receptors are not expressed on cochlear cells, at least in rats. This in turn suggests that variation in cochlear responses during the estrus cycle are not the result of the direct effect of estrogen on the cochlea. Such variation may, however, be caused by systemic changes in fluid regulation induced by estrogen receptors at a distant site, or by other hormone receptors.
