Lucid interval
Lucid Interval
A lucid interval (pronounced: loo-sid in-ter-val) is a medical term that refers to a temporary period of improvement or recovery after a traumatic brain injury, specifically an epidural hematoma. During this period, the patient may appear to be normal and conscious, despite having suffered a significant injury.
Etymology
The term "lucid interval" is derived from the Latin words "lucidus" meaning clear, and "intervallum" meaning space between. It was first used in medical literature in the 19th century to describe the period of apparent recovery after a head injury.
