Sometimes, mood swings and even depression can occur. Speaking normally, understanding what other people are saying, memorizing things, and eating can become difficult. īrain injuries can have many other symptoms besides movement problems. Axon damage can lead to the inability to move normally. Another common type of diffuse brain injury involves damage to the axons, which are the parts of brain cells that transport signals between the brain cells and the body. In many of these injuries, less oxygen flows into the brain, similar to what happens in hypoxia. ĭiffuse injuries occur over a larger area of the brain.

The three meninges are called the dura, arachnoid, and pia mater.Figure 2 - The membranes covering the brain and spinal cord are called the meninges.As you can see in Figure 1, the brain is divided into different parts, each with a different job. Focal means that the injury occurred in a specific part of the brain. TBIs can also be grouped into two types: focal vs. Some common examples of secondary injuries include inflammation (where brain tissue and blood vessels swell), hypoxia (when there is less oxygen going to the brain), and cellular death. After the primary injury, secondary injury can cause even more damage to the cells and tissues. A primary injury is the initial injury we will discuss what you can do to prevent a primary injury from happening. Or, if you hit your head and the blood vessels in your brain start to bleed, the brain tissue may end up getting squished to make room for the blood.
That means that if you hit your head and the brain swells, there will be less room for blood, which could mean the brain will become even more injured. So, because the space is limited, if there is an increase in any one of these three things, one or both of the other two will have to decrease. The Monroe-Kellie Doctrine states that there is a limited amount of space in the skull to hold all of the cells that make up the brain tissue, the blood that supplies oxygen to the tissue, and a special type of fluid that cushions the brain, called cerebrospinal fluid. So, if you pack too many clothes, you would not be able to pack other things, like your favorite book. If you are packing for a trip, you can only fit in a certain number of items. Introductionīefore we dive into talking about brain injury, we want to introduce something scientists call the Monroe-Kellie Doctrine, which is important for understanding how traumatic brain injury (TBI) happens.
Fortunately, there are ways we can reduce TBI by making safe choices, such as buckling our seatbelts and wearing helmets while playing sports. There are different causes of TBI, such as car accidents, falls, or football tackles. It is a common injury in children and can cause lasting symptoms and disabilities. Traumatic brain injury, or TBI, is an injury to the brain caused by a bump or hit to the head.
