Cervical Spondylosis and Its Unique Characteristics of Dizziness

When it comes to dizziness caused by cervical spondylosis, the symptoms largely depend on the specific type of cervical spine disorder. There are several common scenarios where dizziness can occur as a result of cervical issues.

Neck-Type Cervical Spondylosis and Dizziness

Neck-type cervical spondylosis often involves a straightening or reversal of the natural cervical curve, which can lead to dizziness. Patients with this condition typically experience muscle fatigue and strain in the neck area. The affected muscles are often connected to the greater and lesser occipital nerves. When these attachment points develop aseptic inflammation, it can irritate the nerves, resulting in pain and numbness that begins at the back of the head. These sensations do not remain localized; as the condition progresses, the discomfort can spread across the entire head, causing widespread tension and imbalance.

Vertebrobasilar Insufficiency Due to Vertebral Artery Compression

Another common cause of dizziness in cervical spondylosis is vertebral artery type cervical spondylosis. This occurs when the vertebral artery becomes compressed, leading to reduced blood flow to the posterior circulation of the brain. The primary symptoms include episodes of dizziness and visual disturbances such as temporary vision darkening or blurred vision. These symptoms are typically triggered by sudden head movements or prolonged poor posture, especially in individuals who spend long hours sitting or working at a desk.

Distinguishing Cervical Dizziness from Other Types

It's important to differentiate cervical spondylosis-related dizziness from other forms of vertigo, particularly peripheral or ear-related dizziness. For example, benign paroxysmal positional vertigo (BPPV) is a common condition caused by disturbances in the inner ear's semicircular canals. This type of dizziness is characterized by a sudden sensation of spinning or the room rotating, often triggered by changes in head position, such as lying down or turning over in bed. Unlike cervical vertigo, BPPV is not associated with neck pain or stiffness but rather with a disruption in the body's balance system.

Conclusion

Understanding the specific characteristics of dizziness caused by cervical spondylosis is crucial for accurate diagnosis and effective treatment. If you experience recurring dizziness, especially alongside neck pain or stiffness, it's important to consult a healthcare professional who can help determine the underlying cause and recommend appropriate interventions.
