- •Transient loss of consciousness has a diverse etiology including syncope, orthostatic hypotension, seizures, psychogenic non-epileptic seizures.
- •Serum lactate can be a valuable tool to differentiate generalized tonic-clonic seizures from other forms of transient loss of consciousness.
- •In our study, we found no difference in serum lactate levels in patients with non- generalized tonic-clonic seizure types of transient loss of consciousness, such as syncope, and psychogenic non-epileptic seizures.
- •Serum lactate levels in patients with generalized tonic-clonic seizures were significantly higher than any other cause of transient loss of consciousness, including syncope.
