A symptom like seizures is critical in indicating a severe poisoning case because it often reflects significant neurological impact and instability within the body. Poisoning can lead to various types of seizures, depending on the substance involved and its effects on the brain. Seizures may arise from toxicity that disrupts normal brain function, which can be life-threatening and require immediate medical intervention.

Dizziness, vomiting, and headaches can also occur in cases of poisoning, but they are not as definitive of a critical condition. While dizziness might indicate a reaction, and vomiting can occur due to various toxins, these symptoms do not typically reflect the same level of severity as seizures. Headaches can arise from many conditions, not just poisoning, and are less specific in signaling a severe reaction to toxins. In contrast, seizures serve as a clear indicator that the situation is critical and demands urgent medical attention.
