What is a consequence of neurotoxicity related to ionic contrast media?

Ionic contrast media, which contain high osmolality, have been associated with various side effects, including neurotoxicity. When these substances are introduced into the body, they can impact the nervous system, leading to symptoms such as headaches, seizures, or changes in consciousness. The high osmolality can create an osmotic imbalance, which might lead to the dysfunction of neuronal cells and, in turn, affect heart signals by disrupting the normal electrical conduction that keeps the heart beating regularly. This disruption can result in arrhythmias, which are irregular heartbeats, and neurological symptoms stemming from the brain's response to the toxicity.

These effects highlight the potential risks of using ionic contrast media, particularly in sensitive populations or in cases where there may already be risk factors for neurological issues or cardiovascular instability. In summary, the correct answer points to the real consequences of neurotoxicity, capturing both the cardiovascular and neurological issues that can arise from the administration of ionic contrast media.
