Article Information		Abstract
Review Article Received: 23/07/2026 Accepted: 26/07/2026 Published:31/07/2026   Keywords Vertigo; BPPV; Amaravati;		Background: Vertigo, which is exacerbated by head movement, is the feeling of movement or spinning when none is happening. It is frequently accompanied by nausea, perspiration, or trouble walking.  It is the most prevalent type of vertigo and is frequently brought on by vestibular neuritis, Ménière's disease and benign paroxysmal positional vertigo (BPPV).  Stroke, brain tumors, multiple sclerosis, migraines, trauma and exposure to toxins are fewer common causes.  Unlike other forms of dizziness, such as presyncope or disequilibrium, vertigo typically indicates an issue with the vestibular system.  A prospective observational research design was used for the investigation. Result: Vertigo in 1,670 young people was investigated in this 6-month research conducted in Amaravati.  Positional alterations were responsible for 45.8% of instances of dizziness and unsteadiness, which were prevalent (65.2%).  The most common causes were BPPV (37.9%) and vestibular migraine (25.6%).  Among the treatments were medicine (56.3%), lifestyle modifications (21.2%), and physical therapy (22.5%).  With 83.1% of patients reporting alleviation, physical therapy was quite successful in treating BPPV.  The study emphasizes how common vertigo is in young adults and the need for focused treatments as well as more investigation into long-term effects. Conclusion: The high frequency of vertigo among young individuals in the Amaravati Capital Region emphasizes the importance of early diagnosis and complete treatment. This study highlights significant risk variables, including lifestyle and environmental factors, and lays the groundwork for future research into focused prevention, timely intervention, and effective treatment techniques..

INTRODUCTION:

Vertigo is the sensation of spinning or movement when none exists, often accompanied by nausea, vomiting, balance problems, typically worsened by head movements. It is classified into two types:  peripheral vertigo, caused by inner ear disorders such as benign paroxysmal positional vertigo (BPPV), Ménière’s disease, vestibular neuritis; and central vertigo. Peripheral vertigo is more common and frequently caused by disruptions in the vestibular system. BPPV, the most common cause of positional vertigo, results from displaced calcium crystals (otoconia) in the semicircular canals—most often the posterior canal—leading to brief spinning episodes during head movements [1]. Ménière’s disease causes recurrent vertigo, tinnitus, hearing loss, and ear fullness, affecting approximately 17–200 people per 100,000 worldwide; its causes may include viral infections, detached otoconia, or anatomical change[2] Vestibular neuritis is typically linked to viral infections or ischemia, causing inflammation and vestibular dysfunction [3].Central vertigo arises from lesions in the brainstem or cerebellum due to stroke, tumors, multiple sclerosis, or head injuries, with 30–65% of patients experiencing vertigo or imbalance [4]. Vestibular migraines, transient ischemic attacks, and vascular conditions such as hypertension, atherosclerosis, embolism, and aneurysms can also cause central vertigo[5][6].Other causes include vestibular schwannomas, benign tumors of the vestibular nerve that cause unilateral vertigo, hearing loss, and tinnitus [7]. Superior semicircular canal dehiscence syndrome (SSCDS) caused by a bony defect producing abnormal responses to loud sounds or pressure. Chronic dizziness—a persistent, non-rotational sense of unsteadiness often worsened in visually complex environments[8].Accurate diagnosis, often using the HINTS exam, is essential to differentiate between peripheral and central vertigo [9].Dizziness, which includes symptoms like light-headedness, unsteadiness, and presyncope, lacks a precise definition and may stem from peripheral or central vestibular causes [10]. Diagnostic accuracy improves by focusing on symptom timing, triggers, and using the HINTS exam, which can outperform early neuroimaging in AVS cases [11]. BPPV is the most common cause, especially in older adults, with posterior canal BPPV accounting for over 80% of cases [12]. Other causes include vestibular neuritis, labyrinthitis (viral or bacterial) vestibular migraine and Meniere’s disease, which causes vertigo, tinnitus, and fluctuating hearing loss. Peri lymphatic fistula may result from trauma or surgery and presents with dizziness triggered by pressure or sound (Hennebert's, Tullio's signs) [13]. Patients with vertigo/dizziness have a significantly higher risk of stroke or cardiovascular events[14].BPPV prevalence rises with age, being seven times higher in those over 60 [15]. Vertigo can be triggered by head movements and postures, with shifting positions being the most common cause, affecting about half of individuals during standing or walking [16]. Complications of otitis media can lead to facial paralysis, labyrinthitis, and chronic ear infections [17]. Labyrinthitis can result from infections spreading from the middle ear, causing severe vertigo, nausea, and hearing loss, and in chronic cases, leading to labyrinthine ossification [18]. Comorbidities such as diabetes, hypertension, osteoporosis, and depression are commonly seen in older adults with BPPV [19]. These findings highlight the complex relationship between vertigo, comorbidities, and its increased prevalence with age.The rotatory chair test, a less commonly used vestibular function test, is valuable for measuring the vestibulo-ocular reflex (VOR), particularly in cases of bilateral vestibular hypofunction. It simulates the natural push-pull characteristics of the horizontal semicircular canals (SCCs) and generates nystagmus in most individuals, with only those with profound bilateral vestibular hypofunction showing no nystagmus. Dynamic visual acuity (DVA) tests evaluate VOR by assessing gaze stability during head motion [20]. The Head Impulse Test (HIT) can be used at the bedside to assess VOR, although it has limitations in sensitivity and specificity Pathological HIT is typically associated with peripheral vestibular lesions but may also occur in certain central lesions, such as strokes [21]. Ocular Tilt Reaction (OTR) and Subjective Visual Vertical (SVV) tests are used to differentiate between central and peripheral vestibular dysfunction, with pronounced skew deviation (SD) [22].Romberg, Jendrassik, and balance tests like Single Leg Stance, Tandem Gait, and the Timed Up and Go test further assess stability, with positive tests indicating vestibular dysfunction. For instance, in Romberg testing, the Jendrassik maneuver increases test difficulty, and a test is positive if the subject moves before 30 seconds. In the Single Leg Stance test, the subject must maintain balance with eyes open or closed for up to 30 seconds. The Tandem Gait test requires walking heel-to-toe for 20 steps, and the Timed Up and Go test measures the time it takes to rise, walk 3 meters, turn, and return to the chair. These tests are vital for diagnosing vestibular issues and evaluating the severity of dysfunction [23].

 Vertigo treatment primarily involves vestibular suppressants and antiemetics. Anticholinergics like scopolamine reduce nystagmus [24]. Antihistamines help prevent motion sickness and vertigo symptoms but have side effects [25]. Benzodiazepines, such as lorazepam, are effective at low doses but can cause habituation and memory issues[26]. Calcium channel antagonists, like cinnarizine, are used in Meniere’s disease but are not universally accepted [27]. Antiemetics, such as meclizine, treat nausea, while dopamine antagonists like prochlorperazine are second-line due to side effects[28].For BPPV, physical therapy is the primary treatment, with meclizine helping with nausea [29].In Meniere’s disease, vestibular suppressants manage acute attacks, while salt restriction and diuretics may reduce attacks [30]. Vestibular neuritis is managed with minimal medication and activity encouragement to aid recovery [31]. Bilateral vestibular paresis is typically caused by ototoxic antibiotics like gentamicin following infections such as osteomyelitis or peritonitis. [32]. Central vertigo, a rarer cause (5% of cases in ER settings), is mainly due to vascular disorders like stroke or migraine, with prolonged symptoms. Common treatments include verapamil, amitriptyline, and benzodiazepines. For migraine-related vertigo, SSRIs and β-blockers can also be used. In patients with known CNS lesions, benzodiazepines like lorazepam and prochlorperazine may help. Gabapentin, carbamazepine, or acetazolamide may be used for specific vertigo conditions [33]. Psychogenic vertigo, linked to psychiatric disorders such as anxiety or depression, is treated with psychiatric interventions. Benzodiazepines are effective for anxiety, while SSRIs may help with depression. In cases of somatization or malingering, no medication is prescribed, but reducing unnecessary healthcare usage is the goal [34]. When the cause of vertigo is undetermined, the treatment is empirical, often involving a medication withdrawal strategy and trials of meclizine, clonazepam, or migraine treatments like verapamil. Monitoring is essential, as conditions like Meniere’s disease or acoustic neuromas may evolve over time [35].

RESULTS & DISCUSSIONS

For Online Data

Table 1: Age Vs No. of Participants

Depicts the information regarding the distribution of study subjects within the age groups of 18 years to 25 years. Majority of the subjects were found within the age of 18 years (32.11%), followed by 19 years (19.44%), 20 years (16.49%), 21 years (13.28%), 22 years (7.81%), 23 years (5.90%), 24 years (2.08%) and 25 years (2.86%).

 

 

 

Table 2: Gender Vs No. of Participants

Gender	No. of participants	Percentage (%)	Mean+/-SD
Male	627	54.16%	1.46 ± 0.50
Female	525	45.57%

 

 

 

 

 

Comprising 525 women (45.57%) and 627 men (54.17%), the study had an average age of 1.46 ± 0.50 years. With an average vertigo annoyance score of 2.42, which indicates considerable discomfort, Hackenberg et al.'s study of 8,519 individuals, on the other hand, revealed a vertigo prevalence of 21.6%, peaking in the 55–64 age range. These findings imply that the occurrence and effects of vertigo differ considerably by demographic and age [36].

Table 3: Level of Education Vs No. of Participants

Level of Education	No. of participants	Percentage	Mean +/- SD
High School	59	5.121%	2.23 ± 0.59
Undergraduate	811	70.39%
Graduate	242	21.00%
Other	40	3.47%

 

 

 

 

 

 

Depicts the information regarding the level of education of the participants from high school to graduates and others. Majority of the participants were found as under graduates (70.39%), followed by high school (5.121%), graduates (21.006%) and others (3.472%).

Table 4: Individual no. of responses for question 1

Do you have any known medical condition	No. of participants	Percentage (%)	Mean  +/- SD
Yes	361	31.33%	1.69 ± 0.46
No	792	68.75%

 

 

 

 

 

In our survey of 1,153 people, 31.33% reported having a recognized medical condition, whereas 68.75% did not. Similarly, Sreenivas V et al. discovered that 45.1% of patients had hypertension, with hypertensive patients having greater recurrence rates (38.1%) than non-hypertensive patients (16%), implying a possible relationship between hypertension and recurrence [37].

 

 

 

 

Table 5: Individual no. of responses for question 2

Participants in our study reported migraines (13.88%), ear infections (8.59%), neurological illnesses (2.69%), head injuries (6.33%), others (57.68%), and multiple conditions (10.85%). These findings are consistent with Marcello Cherchi et al., who connected vestibular migraine (VM) to otologic diseases, and Faith W. Akin et al., who discovered that many patients with Meniere's disease also fit migraine criteria. The presence of numerous illnesses emphasizes the intricate link between VM and other medical concerns [38].

Table 6: Individual no. of responses for question 3

 

In our survey, 20.83% of individuals said they took drugs, whereas 79.16% didn't. In contrast, Benedict Katzenberger et al. discovered that 35% of 158 patients with vertigo and balance difficulties were taking anticholinergic or sedative drugs, which were connected to impaired functioning. The reduced medication use in our younger sample could be attributed to demographic variations or treatment patterns, emphasizing the need for additional study on medication management and outcomes in vertigo [39].

Table 7: Individual no. of responses for question 4

In our study, 30.90% of individuals reported having vertigo episodes, whereas 69.09% did not. This is consistent with M von Brevern et al., who discovered that 8% of people with moderate to severe vertigo met the criteria for benign paroxysmal positional vertigo (BPPV), 24% had a history of vestibular vertigo, and 2% experienced frequent vertigo triggered by head movements despite not meeting BPPV criteria [40].

Table 8: Individual no. of responses for question 5

 In our study, 8.68% of patients had vertigo every day, 11.72% weekly, 9.55% monthly, and 70.05% seldom. Casani et al. looked at 249 patients divided by vertigo type and age, concentrating on clinical history and demography. While Casani et al. focused on patient classification and age, our study provides precise frequency data on vertigo episodes across multiple age groups [41].

Table 9: Individual no. of responses for question 6

 In our study, 19.18% of individuals reported spinning feelings, 22.91% light-headedness, 15.71% imbalance, and 42.18% additional vertigo symptoms. R. Teggi et al. discovered 13.7% spinning sensations, 26.3% relapsing episodes, 12.9% positional aggravation, and 4.8% cochlear symptoms. Variations in symptom prevalence between studies may be due to differences in demographics, methodologies, or diagnostic criteria [42].

Table 10: Individual no. of responses for question 7

In our study, 53.73% of individuals had vertigo for less than one minute, 23.52% for one to five minutes, 10.24% for six to thirty minutes,12.5% for more than thirty minutes, demonstrating that vertigo is often brief but can linger longer in some situations. Li W, Cheng Y et al.'s study of 76 patients focused on tumor location and operation type, providing a unique clinical context unrelated to vertigo duration [43].

 

Table 11: Individual no. of responses for question 8

In our study, 14.75% of patients reported vomiting, 15.10% tinnitus, 24.39% headaches, 3.47% vomiting plus tinnitus, and 42.27% other symptoms. Similarly, Magdalena Nowaczewska et al. found that 49.3% of 286 tinnitus patients also had headaches, with this group being more typically female, younger, and having greater rates of vertigo and depression. Both studies emphasize the common coexistence of tinnitus and headaches, with Nowaczewska delving deeper into associated clinical and demographic variables [44].

Table 12: Individual no. of responses for question 9

Our study discovered that vertigo was caused by stress or anxiety (15.02%), rapid head movements (12.93%), position changes (12.85%), brightness or loud noise (7.29%), other factors (38.36%), and numerous triggers (13.54%). These findings show that patients suffering with vestibular migraine (VM) could benefit from targeted mobility, posture, and lifestyle guidance, Xiao BJ et al. back this up by focusing tailored instruction on stress management, exercise, and lifestyle improvements to prevent VM recurrence and enhance outcomes [45].

Table 13: Individual no. of responses for question 10

Our study discovered that 29.92% of subjects observed a pattern or specific times for vertigo attacks, whereas 70.08% did not. Ichijo H et al., on the other hand, found distinct time patterns, with vertigo occurring during sleep, upon rising, in the morning, or afternoon in various patient groups. This implies that, while some people experience time-specific vertigo, many do not show apparent patterns [46].

Table 14: Individual no. of responses for question 11

How does vertigo impact your daily activities? (Rate from 1-5, where 1 = No impact, 5 = Severe impact)	1	2	3	4	5	Mean +/- SD
Work/school	588 (51.04%)	195 (16.92%)	184 (15.97%)	108 (9.37%)	77 (6.68%)	2.14 ± 1.29
Social activities	453 (39.32%)	268 (23.26%)	273 (23.69%)	97 (8.42%)	61 (5.29%)	2.33 ± 1.20
Physical activities	453 (39.32%)	268 (23.26%)	273 (23.69%)	97 (8.42%)	61 (5.29%)	2.33 ± 1.20
Daily tasks	494 (42.88%)	205 (17.79%)	237 (20.57%)	157 (13.62%)	38 (3.29%)	2.09 ± 1.21

 Our study of 1,152 individuals found that, while more than half reported no effect of vertigo on work or school, a significant proportion suffered moderate to severe effects on social activities, physical exercise, and everyday tasks. Similarly, Ayse Gunes-Bayir et al. discovered that persons with vertigo were older, more likely to be overweight, and had different food habits than controls. Together, these data emphasize vertigo's major influence on daily living and the significance of addressing lifestyle and nutritional aspects in its treatment  [47].

Table 15: Individual no. of responses for question 12

Our study discovered that just 25.43% of participants sought medical attention for vertigo, while 74.56% did not, showing that many people shun professional aid. Similarly, Eva Grill et al. found that even when patients contact primary care, vertigo is frequently misdiagnosed or poorly treated before being sent to specialists. These findings show considerable gaps in vertigo management, including underutilization of medical resources and inadequate primary care [48].

Table 16: Individual no. of responses for question 13

 Despite strong recommendations for vestibular rehabilitation and physical therapy to improve vestibular function, only 6.77% and 12.67% of patients underwent them, respectively. Meanwhile, medication use (14.93%) and other therapies (51.04%) were more prevalent, indicating underutilization of rehabilitation. According to Courtney D. Hell et al., this disparity could be attributed to difficulties with guideline implementation and awareness [49].

Table 17: Individual no. of responses for question 14

 Regarding issue 14, 88.71% of participants provided additional feedback, with 5.38% indicating unbalance, 2.34% headaches, 2.69% tension, and 0.86% tinnitus. Unbalance was the most common complaint, but headaches, stress, and tinnitus were all prevalent. These findings are consistent with those of L. E. G. H. de Joode et al., who identified tinnitus, vertigo, and imbalance as typical vertigo symptoms and emphasized the complexity and variety of vertigo episodes, which are frequently isolated and include occasional visual auras [50].

Individual no. of responses for question 15 Depicts the information regarding the responses of number of participants answered the 15th question according to the perceivance obtained along with their respective percentages according to responses given by the participants, the responses to the consent question show that 602 participants (52.25%) consented to participate in the study, while 550 participants (47.74%) did not consent.

 

Table 19: Individual no. of responses for question 16 of vertigo symptoms scale

 

Participants'responses to the Vertigo Symptoms Scale (ranked 0–5 for severity) revealed that "no symptoms" was the most prevalent response across all symptoms, including spinning sensation (54.5%), nausea (47.2%), tinnitus (46.5%). Mild to moderate symptoms were reported by various percentages of subjects, with fewer having severe to very severe symptoms. The study divided participants into moderate (<24) and severe (≥24) vertigo groups based on their cumulative symptom scores, which included spinning, light-headedness, unsteadiness, nausea, vomiting, tinnitus, migraines, hearing loss, difficulties concentrating, anxiety, and fatigue. Çakır et al. found that vertigo can have a considerable impact on health-related quality of life (HRQoL), even with mild to moderate symptoms. [51].

Table 20: Individual no. of responses for question 17 of vertigo symptoms scale

The Dizziness Handicap Inventory (DHI) responses show that dizziness has an impact on daily activities and mental health, with many participants experiencing mild to severe difficulties in balance (e.g., 39.33% reported mild/severe difficulty walking in the dark), concentration (53.55%), anxiety (49.38%), and mobility (up to 37% difficulty with uneven surfaces). Schmid et al. discovered considerable relationships between DHI scores and psychological characteristics such as obsessiveness, phobic anxiety, and quality of life, stressing the importance of emotional and functional components in controlling dizziness. [52].

 

 

 

 

 

 

OFFLINE DATA

Table 21: Age Vs No. of Subjects

Depicts the information regarding the distribution of No of participants within the age groups of 18 Years to 25 years. Majority of the participants were found within the age of 18 years were 142(27.413%), followed by 19 years were 103 (19.88%), 20 years were 109 (21.042%), 21 years were 86(16.60%), 22 years were 44 (8.494%), 23 years were 17 (3.281%), 24 years were 9 (1.737%) and 25 years were 8 (1.544%).

Table 22: Gender Vs No: of subjects

Our study included 518 participants, with females accounting for 54.25% (281) and males for 45.75% (237). In contrast, Michele Ori et al.'s smaller research of 72 vestibular migraine patients found a significantly larger female predominance (88.89% vs. 11.11% men). Ori et al.'s findings show a considerable gender gap in vestibular migraine, whereas our bigger sample provides a more comprehensive picture of gender distribution in the general population [53].

Table 23: BMI Vs No. of subjects

Our study of 518 participants classified their BMI as follows: 17.76% underweight (<18.5), 57.53% healthy weight (18.5-24.9), 17.95% overweight (25-29.9), 4.83% Class 1 obesity (30-34.9), 1.74% Class 2 obesity (35-39.9), and 0.19% Class 3 obesity (≥40). While our work gives a comprehensive picture of BMI distribution in the general population, Dilek Baday-Keskin et al. conducted a smaller study that focused exclusively on BMI's involvement in 31 patients with Benign Paroxysmal Positional Vertigo (BPPV) and 30 controls, demonstrating its relevance to that condition. [54].

Table 24:  Individual no. of responses for Test 4

Our study of 518 participants discovered that the largest group (201 individuals, 38.8%) had pulse rates between 80-90 bpm, followed by 125 (24.1%) at 90-100 bpm, 112 (21.6%) at 60-80 bpm, 78 (15.1%) at 100-110 bpm, and only 2 (0.4%) at 40-50 bpm. In contrast, Serhat Günlü et al. analyzed heart rate variability in 70 vertigo patients, indicating that those with vertigo—especially with arrhythmias—frequently exhibit considerable autonomic nervous system dysfunction indicated by increased sympathetic activity, which can exacerbate upon standing [55].

Table 25:  Individual no. of responses for Test 5

Our study of 518 participants found that a large proportion had normal blood pressure, with 28.18% at 110/70 mmHg and 26.25% at 120/80 mmHg. Elevated readings were uncommon, with 9.07% at 130/80 mmHg and 0.77% at 140/80 mmHg, while 1.74% had low-normal values such as 100/60 mmHg. These findings are consistent with those of Moon-Jung Kim et al., whose smaller study found that the majority of participants' blood pressures were within a healthy range, showing a broadly normal distribution across both investigations [56].

Table 26:  Individual No: of responses for Test 6

Our three-month study of 518 participants found a significant prevalence of vestibular dysfunction: 40.15% bilateral, 27.41% right-sided, and 27.22% left-sided, with just 1.93% having normal head impulse tests. Bilateral dominance was shown in smaller amounts (1.74% left, 1.54% right). This big sample provides a comprehensive overview of vestibular deficits. Paloma Eza-Nuñez et al.'s year-long study of 123 individuals offers deeper long-term insights, but has limited generalizability due to its small size and concentration on chronic patients. [57].

Table 27: Individual No. of responses for Test 7

Our three-month study of 518 younger individuals discovered that only 0.19% had a normal gait, whereas 40.54% had left-sided issues, 33.20% right-sided issues, and 22.97% bilateral abnormalities. This focuses on gait problems in young people. In contrast, Joe Verghese et al.'s 20-month study of older adults found that those with neurological gait problems had a higher fall rate (0.66 vs. 0.43 falls per person-year), emphasizing the long-term fall risk in older populations, whereas our study focuses on short-term gait dysfunction in younger people [58].

Table 28:  Individual No. of responses for Test 8

  Our study of 518 participants discovered that more than 65% (208 people) had balance problems on Romberg's test, with 40.15% having left-sided issues, 33.98% right-sided issues, and 25.68% bilateral problems. Santhosh kumar Rajamani et.al.., Only 0.19% demonstrated normal equilibrium. These results are consistent with the comparator group, emphasizing the significant incidence of balance impairments, particularly on the left side, as well as the rarity of normal balance among individuals [59].

Table 29: Individual no: of responses for Test 9

 

 Our study of 518 people utilizing rotatory chair tests found that vestibular dysfunction mostly affected the left ear (35.52%), followed by bilateral issues (31.85%) and right ear problems (29.52%), with only 0.58% demonstrating normal vestibular function. This demonstrates the universality of vestibular dysfunction on the ear side. In contrast, Mathias Winther Bech et al.'s research of 281 patients highlighted the MRC test's diagnostic accuracy for benign paroxysmal positional vertigo (BPPV), displaying high sensitivity (71%) and specificity (98%). While our study examines the prevalence of vestibular impairment, theirs assesses diagnostic precision for a specific ailment [60].

 

 

 

 

Table 30:  Individual no: of responses for Test 10

 

Our three-month study of 518 participants revealed that just 0.77% had normal finger-nose coordination, whereas 43.44% had difficulty with the left hand, 33.59% with the right hand, and 22.01% had bilateral coordination problems, indicating widespread motor coordination deficiencies. In contrast, Kazuki Nishida et al.'s 12-month research of 357 people found a high (OR 22.6) link between poor finger-nose synchronization and cerebrovascular events such as strokes and transient ischemic episodes. While Nishida et al. emphasize the clinical significance of coordination deficiencies as predictors of cerebrovascular risk, our study examines their frequency in the general population [61].

Table 31:  Individual No. of responses for Test 11

S. No	Skew Deviation Test	No. of Participants	Percentage (%)	Mean ± SD
1 2 3 4 5 6	Bilateral Bilateral>Left Bilateral>Right Left Right Normal	33 0 1 233 195 56	6.37% 0 0.19% 44.98% 37.64% 10.81%	4.40±1.10.

Our study of 518 participants found a high prevalence of skew deviation, with 44.98% showing left eye involvement, 37.64% right eye involvement, 10.81% normal alignment, and 6.37% with moderate deviation. Compared to M. Chandrakumar et al.'s findings on posture-related changes that aid in diagnosis, and Wong's emphasis on clinical differentiation, our data adds valuable prevalence insight to the overall understanding of skew deviation. [62].

CONCLUSION

Given the high prevalence of vertigo among young adults in the Amaravati Capital Region and the importance of early diagnosis and comprehensive management, this study's findings provide a solid basis for future research focusing on targeted prevention, timely intervention, and effective therapeutic strategies to reduce the burden of vertigo in this population. Clinical evaluations identified key risk factors, such as lifestyle and environmental influences, and revealed multiple underlying causes.
