* Typical Absence
differential diagnosis of epileptic seizures
Causes of seizures / evaluation of 1st seizure
- Vascular : intracranial hemorrhage, stroke
- Infections : Meningitis, Brain abscess
- Metabolic : Hypoglycemia, Hyponatremia
- Trauma
- Toxicological : intake or withdrawl of substance
- Oncological : Brain tumor - metastasis
EVALUATION OF THE FIRST SEIZURE
exclude life-thretning conditions such us
❑ Meningitis,
❑ Systemic sepsis,
❑ Unintentional and intentional head trauma,
❑ ingestion of drugs of abuse and other toxins.
