Cognitive Problems and Difficulties
Cognitive 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.
