What outcome can result from excessive use of anti-convulsants?

Excessive use of anti-convulsants can lead to nausea and dizziness as a result of the medications' side effects. Anti-convulsants work by altering the activity of neurotransmitters in the brain to prevent seizures, but high dosages or prolonged use may disrupt normal brain function, leading to various adverse effects. Nausea can occur due to gastrointestinal irritation, while dizziness is linked to central nervous system depression or imbalance in neurotransmitter levels. These symptoms are commonly reported in patients who are either starting or adjusting their dosage of anti-convulsant medications.

In contrast, improved cognitive function, increased muscle coordination, and enhanced respiratory capability are not typical outcomes of excessive anti-convulsant use. In fact, these medications can sometimes lead to cognitive impairment and decreased muscle coordination, particularly if levels in the bloodstream become too high.
