Answer

Answer

When evaluating a child for staring spells, laboratory tests for metabolic abnormalities or toxic or drug ingestion (especially in older children) may be indicated. If a clear history of the episodic nature of the attacks is obtained, then the EEG can be diagnostic and laboratory tests may not be necessary.

When evaluating a child with a developmental delay, or if the EEG reveals atypical absences, then a full work-up for the underlying cause of a symptomatic generalized epilepsy is indicated.
