Depending on the severity of the injury, the patient may have no sensation, awareness, or consciousness.
During a coma, patients may have minimal to no response to sensory stimuli, such as light, sound, or touch. They may appear as if they are in a deep sleep or unconscious state. Some people might experience vivid dreams, hallucinations, or feel like they are in another reality.
The length of time a person is in a coma varies from days to months, and in some rare cases, years. The longer a patient is in a coma, the more likely they are to experience some level of brain damage or cognitive impairment.
Upon waking up, some patients may require a period of rehabilitation to relearn basic skills such as walking, talking, and eating. Others may have longer-term physical or cognitive effects, such as muscle weakness, memory loss, or difficulty concentrating.
Going into a coma is a serious medical condition that can be caused by a variety of factors. It can be a traumatic experience for the patient, and may lead to long-term consequences.
