What are the potential signs of Lithium toxicity?

Lithium toxicity can manifest through various symptoms, and confusion is a significant indicator of this condition. When lithium levels exceed therapeutic ranges, it can affect neurological function, leading to alterations in mental status, including confusion, disorientation, and cognitive disturbances. This cognitive impairment occurs because lithium affects neurotransmitter systems and can have a neurotoxic effect at high levels.

In contrast, potential signs associated with increased energy levels, improved coordination, or a decreased heart rate are not consistent with lithium toxicity and are not typically observed in such cases. Instead, individuals experiencing lithium toxicity may exhibit lethargy or increased fatigue, and physiological responses can vary widely based on the severity of the toxicity. Understanding these symptoms is crucial for early recognition and management of lithium toxicity.
