Which term best matches the following definition: Neurologic disorder with sudden recurring seizures of motor, sensory, or psychic malfunction?

• A. Epilepsy
• B. Hypothyroidism
• C. Hyperthyroidism
• D. Leukemia

Answer: (A)

This item tests recognizing a brain-based condition defined by repeated seizures. Seizures happen when areas of the brain become briefly overactive, causing sudden changes in movement, sensation, or thinking. When these seizures occur repeatedly and not just because of a temporary trigger (like fever or injury), the condition is called epilepsy. The description fits epilepsy because it points to a neurologic disorder with sudden, recurring seizures that can affect motor function (uncontrolled movements), sensory experiences (odd sensations), or changes in mental function (thinking or emotions). The other options describe different health problems—not seizures or brain-based disorders—so they don’t match the definition.
