- Unlike an epidural hematoma, which usually progresses quickly and has external symptoms, subdural hematomas can often be "ticking time bombs". As the veins are not always under pressure, they can progress slowly and not show other symptoms until days or even weeks after a head injury. In addition, a subdural hematoma will show no sign on the outside of the skull.

| - A subdural hematoma was a type of brain injury, similar in nature to an epidural hematoma. (VOY: "Gravity") In 2370, Doctor Beverly Crusher and nurse Alyssa Ogawa had to prepare an emergency surgery for a comatose patient with a subdural hematoma, the Cardassian Joret Dal. (TNG: "Lower Decks" ) In 2372, The Doctor searched for a subdural hematoma as one of several potential causes for Captain Janeway experiencing hallucinations.

- Unlike an epidural hematoma, which usually progresses quickly and has external symptoms, subdural hematomas can often be "ticking time bombs". As the veins are not always under pressure, they can progress slowly and not show other symptoms until days or even weeks after a head injury. In addition, a subdural hematoma will show no sign on the outside of the skull. Once a subdural hematoma is detected in a scan, if it is not serious the patient can be monitored and it will often correct itself. However, if the hematoma is serious, it usually requires some type of surgery. This can range from minimally invasive to opening up the skull to stem the bleeding. However, in rare cases, the hematoma may be inoperable and all that can be offered is palliative care.
