Summary
Sleep apnea is linked to dizziness, with higher incidence and prevalence found in affected individuals. Continuous positive airway pressure treatment may resolve dizziness, but more research is needed.
Area of Science:
- Neurology
- Sleep Medicine
- Otolaryngology
Background:
- Dizziness is an underrecognized symptom in patients with sleep apnea.
- Growing evidence suggests a link between sleep apnea and dizziness.
Purpose of the Study:
- To systematically review and synthesize existing research on the relationship between sleep apnea and dizziness.
- To summarize the current evidence on the association between sleep apnea and dizziness.
Main Methods:
- A scoping review was conducted using Arksey and O'Malley's five-stage framework.
- Searches were performed in Embase, PubMed, CINAHL, and Cochrane Library, supplemented by a hand search.
- Twenty-one studies, including case reports and various observational designs, were included.
Main Results:
- A higher incidence of dizziness was observed in individuals with sleep apnea.
- A greater prevalence of sleep apnea was found in individuals experiencing dizziness.
- Significant associations were noted between dizziness severity and sleep apnea severity.
- Continuous positive airway pressure (CPAP) treatment often led to dizziness resolution.
Conclusions:
- Evidence indicates a relationship between sleep apnea and dizziness.
- Limitations include study design (e.g., cross-sectional) and sample sizes.
- Considering sleep apnea in dizziness evaluation is recommended.
- Further research is required to establish causality.

01:26Respiratory Volumes and Capacities I
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
01:30Alterations in Respiration II
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

01:24Sleep-Wake Cycles
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).

NREM sleep comprises four progressive stages that seamlessly merge:

01:17Sleepwalking and Sleep Talking
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

01:21Sleep Apnea
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

01:18Nightmares and Night Terrors
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.
