The cognitive effects of a brain injury affect the way a person thinks, learns and remembers. Different mental abilities are located in different parts of the brain, so a head injury can damage some, but not necessarily all, skills such as speed of thought, memory, understanding, concentration, solving problems and using language.

The cognitive system can be divided up into six separate areas:


Memory is not one thing or one skill on its own. It is easily damaged by brain injury because there are several structures within the brain which are involved in processing information, storing it and retrieving it. Damage to those parts of the brain on which these abilities depend can lead to poor memory. Problems with memory is a complex subject and is covered in more depth in a separate section.

Headway has produced a publication Memory Problems After Brain Injury that provides further information.

Attention and Concentration

A reduced concentration span is very common after head injury, as is a reduced ability to pay attention to more than one task at the same time. These problems are usually caused by damage to the frontal lobe. Attentional problems tend to get worse when the person is tired, stressed or worried. When there are problems with concentration, other skill areas can be affected. It is difficult to follow instructions, plan ahead, be organised and so on, when there is a problem concentrating. Working in a place with as few distractions as possible can help and, as concentration improves, distractions can be increased. In this way, someone can slowly learn to concentrate better in a world which is crowded with distracting sights and sounds.

Speed of Information Processing

Slowing down the speed at which the brain performs the task of information processing is often due to 'diffuse axonal damage' caused by a shake up of all of the pathways the brain uses to transmit messages. This results in problems such as not understanding fast speech, being unable to absorb instructions first time around, and not being able to quickly formulate a reply to a question. To improve the speed of information processing, it is advisable to keep mentally stimulated at the right level to avoid overload.
