2. How Does One Fall into a Coma?

The causes of comas are vast. Sometimes, pre-existing medical conditions cause comas, including diabetes and severe infections. Often, however, comas are caused by a sudden event such as a brain injury in an accident or a stroke. Even healthy people can experience a traumatic injury and enter a coma. Severe damage to the cerebral hemisphere of the brain affects the organ's ability to send neural signals. This lack of signaling results in a coma.
