Decreased consciousness is a condition when a person is less or unable to respond to any stimuli. This condition can be caused by fatigue, injury, illness, or side effects of medications.
Awareness itself is a condition when a person can provide an appropriate response to the environment and people around him. Awareness is also characterized by a person's understanding of who he is, where he lives, and at that time.
When a person's consciousness decreases, his ability to respond will decrease, so he will find it difficult to recognize himself, other people, place, and time.
Loss of consciousness is different from fainting. Fainting only lasts for a while and the person who experiences it will be fully aware afterward, while the loss of consciousness can occur for a longer time, it can even take years.
