What is head trauma, the cause of Bob Saget death?

As per News Medical Life Sciences, the term "head trauma" refers to any injury that causes damage to the scalp, skull, or brain. There are various ways to classify head injuries:

1) Closed Injury: A closed injury occurs when the skull is not damaged or brain tissue is not penetrated. Even if the skull is not broken, this type of injury can still cause brain damage through swelling or bruising, for instance.

2) Open Injury: The term "open injury" refers to damage that penetrates the skull and causes problems such as bleeding in the brain, skull fractures or the pressing of bones against brain structures. Injuries of this type usually occur when a person is moving at high speed and collides with a windscreen during an accident, for example. Gunshots to the head are another example.

3) Concussion: This type of injury involves shaking of the brain, which may or may not involve a blow to the head. Effects of concussions can range from headaches to loss of consciousness.

4) Primary or secondary lesion: A head injury can be classified based on the type of lesion involved. A primary lesion is caused by the displacement of physical brain structures due to an initial injury to the head. Secondary injury develops over time and is due to cellular processes rather than mechanical damage. A secondary lesion can develop as a result of a primary lesion or may occur independently.

5) Primary injury: A primary injury is an injury that is caused directly by an initial head injury. The most common primary injuries are contusions (bruising or hematomas), vascular damage, and axonal shearing (torn and stretched nerves). Primary injury damages the blood-brain barrier and the meninges and may result in neuronal death, which may occur at random.

6) Secondary injury: Usually, a secondary injury occurs not because of mechanical means, but because of complications caused by the primary injury, such as inadequate blood flow in the brain (ischemia), reduced oxygen supply to the brain (hypoxia), low blood pressure, increased intracranial pressure, or swelling in the brain (cerebral edema).
