What is Cognition?
Cognition refers to a whole range of different intellectual processes our brains undertake to perform tasks and keep us functional. An easy way to understand cognition is to think of it in terms of memory and thinking.
When we can think clearly and remember things well, our cognitive ability is good since we have the information immediately to hand.
If either memory, or thinking were somehow disrupted, then our ability to process information would be impaired. Description of the how we use our cognitive skills:


to focus, maintain and divide attention (concentration)

to learn and remember new things

to think, reason and solve problems

to plan, carry out and monitor our own activities

to understand and use language

to recognize objects and assemble things together

to judge distances (spatial skills)




Cognitive Problems and DifficultiesCognitive problems and difficulties associated with multiple sclerosis are more common than was once thought. Previously, it was thought that multiple sclerosis was purely a physical disorder and that intellectual and mental functioning were left virtually intact.
However, this is now known not to be the case and that at least 50% - 60% of people who develop multiple sclerosis will develop some form of cognitive dysfunction as a result. This figure may yet rise as future studies shed more light on the range and extent of cognitive dysfunction associated with multiple sclerosis.

What Is Cognitive Dysfunction?There is no single description which fully encompasses the term, 'cognitive dysfunction'. It really applies to a whole raft of different problems and issues associated with, and related to; intellectual functioning.
For most people who develop some kind of cognitive dysfunction, usually mild; impairment typically means difficulties with thinking clearly, problems with recall (particularly very recent events) and decreased concentration.
For some, around 10% of people with multiple sclerosis, the impairment to their cognitive functioning will eventually become severe enough to significantly interfere with daily living.

What are the Signs of
Cognitive Dysfunction?Initial signs of cognitive dysfunction are typically very subtle (although this may not always be the case) and tend to be recognized retrospectively with the benefit of hindsight. It may even be noticed first by a partner or other family member.
Language processing, concentration and memory problems are the most common presentations of cognitive dysfunction.
'Finding the right words' is a common complaint relating to language use, where the person knows what they would like to say but is unable to 'find the words'.
Concentration may result in a person beginning a task, becoming distracted by another but beginning the new task before finishing the first, and so it goes on and on, until there are numerous unfinished chores or tasks.
Memory problems too, present a challenge for people with multiple sclerosis, particularly short term memory. This tends to show itself as a failure to remember basic things such as the name of a familiar item or animal, for example.The range of cognitive dysfunctions which can be associated with multiple sclerosis:


Verbal fluency and language skills can be impaired

Intellectual reasoning can be impaired

Inability to learn quickly

Poor problem solving abilities

Information processing can be slowed

Poor concentration

Poor judgment
