stunned

Stunned is an adjective used to describe a temporary state in which a person or animal is unable to think clearly or respond normally. It often follows a sudden shock, surprise, or blow, but can also result from medical conditions, intoxication, or sensory overload. The term is colloquial and not a formal medical diagnosis; clinicians may instead describe the underlying condition, such as concussion, syncope, or intoxication.

In humans, being stunned typically involves confusion, slowed cognitive processing, a brief memory gap, or dizziness. It may be accompanied by jaw slackness, staring, or impaired balance. Most episodes last seconds to minutes and resolve as the brain regains function. When unconsciousness occurs or symptoms persist, medical evaluation is advised, especially after head injury, prolonged confusion, or repeated episodes.

In animals and industry, the related term stunning refers to a controlled process that renders an animal insensible to pain before slaughter or euthanasia. Methods include electrical stunning, mechanical methods such as a captive bolt, and gas stunning. The practice is intended to minimize suffering, but welfare standards and regulatory requirements vary by country and context, and the use of each method is typically subject to oversight.
