Relationship between benign paroxysmal positional vertigo (BPPV) and sleep quality.

Area of Science:

• Neurology
• Sleep Medicine

Background:

• Benign paroxysmal positional vertigo (BPPV) is a frequent cause of vertigo, often triggered by head position changes.
• The link between sleep quality and BPPV remains under-researched.

Purpose of the Study:

• To investigate and compare sleep quality between individuals diagnosed with posterior canal BPPV and a control group without BPPV.

Main Methods:

• 120 posterior canal BPPV patients and 120 controls were enrolled.
• Demographic data, BMI, smoking status, and medical history were collected.
• The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality.

Main Results:

• BPPV patients reported significantly worse subjective sleep quality, more sleep disturbances, increased use of sleep medication, and greater daytime dysfunction.
• Poor sleep quality (PSQI score >5) was prevalent in 35% of BPPV patients versus 13.3% of controls.
• Poor sleep quality was more common in patients with BPPV duration exceeding 12 months (57.6%) compared to those with shorter duration (26.4%).

Conclusions:

• Individuals with posterior canal BPPV exhibit diminished sleep quality compared to non-BPPV individuals.
• Sleep quality is particularly poorer in women and those with BPPV symptoms lasting over a year.
• Clinical attention to sleep quality is recommended for patients diagnosed with BPPV.
