Lucid interval may be seen in?
Show Hint
Besides extradural bleed, which listed mental state has a sane gap between two abnormal phases?
Updated On: Jun 24, 2026
- Intracerebral hemorrhage
- Alcohol intake
- Insanity
- Subdural hemorrhage
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: The phrase lucid interval describes a window of normality sandwiched between two abnormal states. It carries weight in two fields: traumatic brain injury and the medico-legal assessment of mental illness.
Step 2: Classically, the head-injury lucid interval belongs to extradural (epidural) bleeding, where a short conscious gap precedes collapse. In the psychiatric sense, it is the spell of clear sanity that separates two episodes of insanity.
Step 3: Scanning the choices, insanity is the listed condition that genuinely shows a lucid interval. Legally this matters because during such an interval the individual can execute a valid will, testify validly, and remains answerable for their acts.
Step 4: The remaining options fail. Intracerebral and subdural haemorrhages tend to evolve without the textbook lucid gap of extradural bleeds, and alcohol intake alone does not generate one.
\[\boxed{\text{Insanity}}\]
