Blurred consciousness: A disorder of consciousness in which the level of consciousness is mildly reduced and deeper than drowsiness. The patient can maintain simple mental activities, but the ability to orient to time, place and people is impaired. The hazy state of consciousness is clinically characterized by a narrowing or narrowing of the range of consciousness, accompanied by a decrease in the level of clarity of consciousness. The conscious activity is concentrated within a narrow and isolated range, and the patient is able to perceive only this part of the experience. From the outside, the patient is able to maintain fairly normal behavior and may perform certain quick actions, but has difficulty perceiving and judging things outside this range, and even gives incorrect evaluations. In this state, the patient may also experience disorientation, hallucinations, delusions and delusions, and may be motivated by hallucinations and delusions to act aggressively or endanger others around them. The hazy state of consciousness is usually episodic, with sudden onset and termination, and the duration is generally short, from a few minutes to a few hours, and sometimes up to several days, but less common. After the seizure, the patient usually falls into deep sleep, and the recovery of consciousness is often accompanied by complete amnesia, and in a few cases, partial amnesia. In some cases, hallucinations and delusions may be retained for the first minute after the end of consciousness, and then disappear completely. This condition is called late-onset amnesia. Hazy states are more often seen clinically in epileptic psychiatric disorders and hysteria, but can be seen in reactive psychosis cranio-cerebral injury, infection and poisoning, and somatic diseases.
