Diagnosis and Management of Severe Dizziness in an Elderly Patient

QUESTION

S.B. is a 70-year-old Hispanic female who presented to the office today with complaints of severe dizziness, nausea, and vomiting. She states that she has had bouts of dizziness over a 3-day period, and the nausea increased to the point that she had two vomiting episodes since awakening early this morning. She feels like the room is spinning for a few seconds; then it stops, and she feels off-balance. She is currently being treated for hypertension with atenolol 50 mg daily and hydrochlorothiazide 25 mg daily. She occasionally uses extra-strength Tylenol for mild joint stiffness. She has never smoked and has an occasional cocktail when out to dinner with friends (one to two/month)

Physical Exam Findings:

VS: BP supine 136/88 RA (right arm), 138/88 LA (left arm), HR 76; standing 134/86 RA, 136/86 LA, HR 78; RR 20, temp. 97.4

Skin: pale, dry, and turgor-fair. Mucous membranes and nail beds are pink. No jaundice or bruising noted

HEENT: Eyes: No AV nicking. No exudates or hemorrhages were noted. Disk is well margined. EOMs intact, peripheral vision intact, and visual acuity (OD, right 20/40, OS, left 20/30) corrected with glasses Ear: TMs gray, light reflex present. Rinne/Weber within normal limits. No carotid bruits were heard.

CV: S1 and S2 RRR. No murmurs, gallops, or rubs

Lungs: clear to auscultation

Abdomen: soft, nontender bowel sounds in all four quadrants. No hepatosplenomegaly

Extremities: full range of motion in the upper and lower extremities. Peripheral pulses +2; no peripheral edema

Neuro: alert and oriented X 3, CNs intact. Motor function, muscle strength, and gait are normal.

State the primary diagnosis that you are considering.  Include the pathophysiology and pertinent positives and negatives.

What laboratory tests will you order for this patient? Include rationale.

What radiological examinations would you order for this patient? Include rationale.

Describe your treatment plan, including non-pharmacological and pharmacological measures. Include rationale.

What additional patient teaching may be needed?

ANSWER

Diagnosis and Management of Severe Dizziness in an Elderly Patient

Introduction

S.B., a 70-year-old Hispanic female, presents with severe dizziness, nausea, and vomiting. The primary diagnosis under consideration is Benign Paroxysmal Positional Vertigo (BPPV). BPPV is a common cause of vertigo, typically triggered by certain head movements. It occurs when small calcium carbonate crystals in the inner ear become dislodged and disrupt the balance system.

Pathophysiology and Pertinent Findings

BPPV typically presents with brief, intense episodes of vertigo triggered by head movements, such as rolling over in bed, tilting the head, or looking up. This is in line with S.B.’s complaints of the room spinning for a few seconds, especially with changes in head position. Her physical exam findings do not reveal any significant abnormalities. Notably, her cardiovascular and neurological systems are intact, ruling out more serious conditions like stroke or Meniere’s disease. BPPV can occur without warning, but its exact cause often remains unknown, especially in elderly patients.

Laboratory Tests

Laboratory tests are generally not necessary for diagnosing BPPV. However, if there is any concern about electrolyte imbalances due to vomiting, a basic metabolic panel may be considered to rule out other causes of dizziness.

Radiological Examinations

The primary radiological examination for suspected BPPV is a Dix-Hallpike maneuver, which involves moving the patient’s head into specific positions to provoke the characteristic vertigo and nystagmus seen in BPPV. Imaging studies like CT scans or MRIs are not typically required for diagnosing BPPV, but they might be considered if the clinical presentation is atypical or if other neurological conditions are suspected.

Treatment Plan

Non-pharmacological Measures
Epley Maneuver: The Epley maneuver is a simple, non-invasive procedure that can be performed in the office. It involves a series of head position changes to guide dislodged inner ear crystals back to their proper place. This should be considered as the first-line treatment for BPPV.
Home Exercises: Encourage S.B. to perform vestibular rehabilitation exercises at home to aid in symptom relief and long-term management.

Pharmacological Measures
Antiemetics: Prescribe antiemetics to alleviate the nausea and vomiting, as needed, to provide symptomatic relief.

Patient Teaching

Vestibular Precautions: Instruct S.B. to avoid sudden head movements and maintain caution when getting up or lying down.
Follow-up: Schedule a follow-up visit to assess the effectiveness of the Epley maneuver and monitor any recurring symptoms.
Medication Compliance: Ensure S.B. takes antiemetics as prescribed to manage symptoms effectively.
Balance and Fall Prevention: Discuss fall prevention strategies and the importance of maintaining balance, particularly in older adults.
Lifestyle Modification: Advise S.B. to limit alcohol consumption, as alcohol can exacerbate vertigo.

Conclusion

In conclusion, the primary diagnosis for S.B.’s condition is Benign Paroxysmal Positional Vertigo (BPPV). The pathophysiology involves dislodged inner ear crystals causing dizziness triggered by head movements. Initial management includes non-pharmacological measures, primarily the Epley maneuver, and antiemetics for symptom relief. Radiological examinations are generally not necessary for diagnosis. Patient teaching on vestibular precautions, medication compliance, fall prevention, and lifestyle modification is essential to ensure a successful treatment outcome and improve S.B.’s quality of life.
