Cerebrospinal fluid

Mechanism and function

Also called CSF, it contributes to mechanical protection and the central nervous system environment. It differs from joint fluid and the contents of an intervertebral disc.

Assessment and clinical implications

Lumbar puncture may analyze its composition when indicated. Suspected leakage, infection or obstruction requires medical assessment and cannot be diagnosed by palpation.

Points to consider

Cerebrospinal fluid and blood circulation are distinct, although both support nervous-system function. Pressure, flow and composition are not interchangeable. Investigation belongs within a medical assessment tailored to the clinical question.

Role of TAGMED care

At TAGMED, assessment aims to understand symptoms, history and functional limitations. Manual care and osteopathy, motorized spinal decompression, laser and shockwave have different indications. The term described in this entry is not enough to select any of these modalities. Their relevance, limitations and possible contraindications should be discussed in relation to diagnosis and individual goals.

Related concepts and distinctions

These concepts belong to the same field, but are not synonyms.

• Cerebrospinal fluid circulation — Production, movement and clearance of cerebrospinal fluid between the ventricles and spaces around the brain and spinal cord.
• Spinal cord perfusion — Blood supply to the spinal cord that delivers oxygen and nutrients and removes metabolic by-products.
