Abstract:
Fifty cases of idiopathic epilepsy and 25 age and sex matched normal healthy controls were studied. There was a significant fall in serum magnesium levels in idiopathic epilepsy on day one and 4 of the seizures (P < 0.01) as compared to controls, and was not decreased significantly on day 7 of the seizures (P < 0.05). The fall was maximum in status epilepticus and severe epilepsy than in mild and moderate epilepsy. Serum magnesium took less time to come back to normal in mild and moderate epilepsy than in other types. This shows that serum magnesium does have a prognostic significance. Lesser the fall in the magnesium levels, less frequent were the convulsions and vice versa. It is concluded that serum magnesium continues to be a sensitive early diagnostic index of idiopathic epilepsy.
Insights
Serum magnesium levels significantly decrease during seizures in idiopathic epilepsy, indicating its prognostic value. Lower magnesium levels correlate with more frequent convulsions, highlighting its role as an early diagnostic marker.
Area of Science:
- Neurology
- Biochemistry
Background:
- Idiopathic epilepsy is a neurological disorder characterized by recurrent seizures.
- Serum magnesium levels have been investigated for their potential role in epilepsy.
Purpose of the Study:
- To investigate the correlation between serum magnesium levels and idiopathic epilepsy.
- To assess the prognostic significance of serum magnesium levels in epilepsy patients.
Main Methods:
- A study involving 50 idiopathic epilepsy cases and 25 healthy controls.
- Serum magnesium levels were measured on days 1, 4, and 7 of seizures.
- Comparison of magnesium levels between epilepsy patients and controls, and across different epilepsy severities.
Main Results:
- A significant fall in serum magnesium was observed on days 1 and 4 post-seizure (P < 0.01) compared to controls.
- Magnesium levels did not significantly decrease by day 7 (P < 0.05).
- The decrease was most pronounced in severe epilepsy and status epilepticus; recovery was faster in mild/moderate cases.
Conclusions:
- Serum magnesium levels serve as a sensitive early diagnostic index for idiopathic epilepsy.
- Serum magnesium levels demonstrate prognostic significance, with lower levels correlating to more frequent convulsions.
