During which of the following types of seizures would a patient be likely to experience déjà vu?

• A. Myoclonic
• B. Complex partial
• C. Generalized non-convulsive
• D. Atonic

Answer: (B)

The experience of déjà vu is most commonly associated with complex partial seizures. During these seizures, patients may have alterations in consciousness and experience various types of sensory phenomena, including feelings of familiarity or déjà vu. This occurs due to abnormal electrical activity in the temporal lobes, which are areas of the brain involved in memory and emotional responses. In complex partial seizures, individuals may also exhibit automations—repetitive, purposeless movements—along with their altered awareness. Despite the loss of consciousness, the sensation of déjà vu can occur as the brain misinterprets certain stimuli, causing the individual to feel as though they have experienced a situation before. The other types of seizures listed typically do not include déjà vu as a symptom. Myoclonic seizures are characterized by sudden, brief jerks of muscles; generalized non-convulsive seizures often manifest as absence seizures, which involve staring spells without the component of déjà vu; and atonic seizures involve a sudden loss of muscle tone without any specific sensations such as déjà vu. Each of these kinds of seizures has a different mechanism and symptom profile, making complex partial seizures the most relevant choice for this particular experience.
