lucid interval
NEUROLOGY
A period (allegedly) preceding the loss of consciousness and coma in patients with subdural and epidural haematomas and intracranial oedema, during which a patient is (allegedly) alert and oriented enough to get in a car after a traumatic event and drive to hospital.
Note: Whilst this phenomenon is well-described in the literature and a favourite for medical student exam questions, it is so rarely seen in clinical practice, that it is almost urban legend
Synonyms Latent interval, latent period, lucid period
