Parts Of Brain And How They're Affected By Trauma


Brain injury symptoms come in many forms. This often makes it hard to diagnose brain trauma. The reason is that they affect different parts of brain differently. An injury to the frontal lobes will cause certain symptoms while an injury to the brain stem will produce others. This article focuses on parts of the brain and the symptoms they produce from trauma.

The Cerebrum

Parts of Brain TraumaOf all parts of brain, the cerebrum is the most often damaged. That's because it's the outer layer of your brain, or the "grey matter." It's separated into lobes that each handles various mental and physical functions. In general, the cerebrum controls cognition, muscle control, personality, voluntary movements, memory and the processing of sensory information.

The Frontal Lobe

Damage to the frontal lobe is often the most dramatic of all the parts of brain. It can include personality changes, mood swings and socially inappropriate behavior. A person who suffers from trauma here may seem to change completely. You may also see trouble solving problems, difficulty making simple movements and, in serious cases, paralysis.

The Parietal Lobe

Trauma to the parietal lobe is marked by language difficulties. The person may have trouble speaking, writing and reading. It also produces problems with body awareness and spatial relationships.

The Occipital Lobe

Since the occipital lobe is one of the parts of brain mostly concerned with vision, trauma sufferers usually have visual problems. They may have blurry vision or double vision. In some cases, it causes blindness. There may also be trouble recognizing things visually and hallucinations.

The Temporal Lobe

The temporal lobe also deals with language. Trauma here will cause trouble speaking, understanding the language, remembering things and categorizing things.


Located at the base of the skull, damage to the cerebellum interferes with coordination, balance and motor actions. A person with trauma here will have lack of coordination and slurred speech.

The Limbic System

Damage to the limbic system is often very severe since this is the brain's control center. It sends information to all other parts of brain. It also controls "primitive" emotions such as fear and rage, and some aspects of memory. A person with trauma here may experience emotional disturbances such as bursts of rage. They might have lack of energy, sex drive and focus. Trauma here also interferes with memory processing.

Brain Stem

The brain stem deals with involuntary functions. Damage here impairs physical, cognitive and behavioral functions. Actually, a concussion is mild damage to the brain stem. Serious damage could cause a coma or vegetative state.

It's important to know all of the parts of brain so that you understand the differences between brain injury symptoms. Each of the parts of brain displays symptoms differently.
