A mild brain injury will usually have symptoms that only last a couple of minutes or a couple of hours at a time but can persist for weeks. These types of injuries can occur from a small fall or even a minor car accident.

A brain injury that is considered moderate or even severe can lead to unconsciousness. This unconscious state can last for an unknown period of time and can take days, weeks, or months.

Typically, a severe brain injury can include a:

• Vegetative state
• Coma
• Semi-consciousness
• Inability to move or speak
• Paralysis of the body

Brain injuries can lead to fatalities well after the inciting incident, so it is important that you receive medical attention even if you are unsure whether or not you need it. In many brain injury cases, a patient’s symptoms do not show up until days later. If you or someone you know has suffered a blow to the head contact a doctor immediately if any of the following symptoms develop.
