What type of DCS involves neurological symptoms?

Type 2 decompression sickness (DCS) is characterized by neurological symptoms, which can manifest as varying degrees of difficulty in coordination, sensory disturbances, headaches, or even loss of consciousness in severe cases. This form of DCS occurs when nitrogen bubbles form in the body's tissues and can impair blood flow or damage nerve tissues, leading to neurological impairments.

In contrast, Type 1 DCS primarily affects the body's tissues and joints, typically resulting in pain, while Type 3 DCS is less commonly referenced and generally involves symptoms not classified strictly as neurological. Type 4 DCS is associated with long-term chronic conditions resulting from repeated DCS exposure, rather than acute neurological symptoms.

Understanding the types of decompression sickness and the associated symptoms is crucial for recognizing and managing the condition effectively, particularly in diving scenarios where rapid pressure changes occur.
