Partial paralysis and severe headache are symptoms of which type of DCS manifestation?

Partial paralysis and severe headaches are symptoms that are primarily associated with central nervous system (CNS) manifestations of decompression sickness (DCS). When a diver is exposed to rapid changes in pressure, nitrogen bubbles can form in the bloodstream and tissues. If these bubbles affect the brain and spinal cord, they can lead to neurological symptoms. This could include partial paralysis due to nerve damage or impairment and severe headaches resulting from pressure on the brain or disruption of normal blood flow.

CNS manifestations can be particularly concerning because they indicate that the bubbles are affecting vital neurological functions and structures, which can lead to serious, long-lasting consequences if not treated promptly. Given the nature of the symptoms in the question, CNS manifestations directly account for those neurological disturbances and are considered a critical and dangerous aspect of DCS.

Other types of DCS manifestations, such as skin manifestations, bends, and chokes, involve different symptoms and areas of the body. Skin manifestations usually result in rashes or itching, bends typically involve joint pain, and chokes are related to lung complications, none of which correlate with the neurological effects described in the question. Thus, option B accurately reflects the symptoms presented.
