Among the signs of strangulation, which symptom indicates more severe trauma?

Each of the listed symptoms can indicate the effects of strangulation, but when considering which symptom suggests more severe trauma, it's important to recognize how they relate to potential underlying injuries.

Headaches can be common following any trauma, but they do not necessarily indicate the level of injury severity on their own. Similarly, memory loss might occur due to a variety of factors, including stress or concussion, but it doesn't always correlate directly with severe trauma resulting from strangulation.

Vision changes, however, can often indicate serious issues, potentially relating to neurological damage or compromise to the vascular supply to the eyes and brain, suggesting a more critical level of injury. In the context of strangulation, vision changes might signify damage that affects the central nervous system or blood flow, which could lead to longer-term impacts or complications.

Given that all these signs can point to trauma, the choice that includes all of them correctly captures the range of potential symptoms observed after strangulation. Each symptom, when presented together, emphasizes the importance of a comprehensive assessment. Detecting any of these signs, especially vision changes, warrants immediate medical attention to evaluate the severity of the injuries.
