In fibromyalgia, cognitive symptoms are worse than in rheumatoid arthritis

Published 28 Jun 2016

In fibromyalgia, cognitive symptoms are worse than in rheumatoid arthritis
A team of researchers from Rush Medical College, Chicago, and colleagues at other institutions recently did a comparative study of the cognitive functions of fibromyalgia (FM) patients versus rheumatoid arthritis (RA) patients. The study, which was called “Cognitive Symptoms in Fibromyalgia Patients Compared with Rheumatoid Arthritis (RA) Patients”, was presented at the Annual Meeting of the American College of Rheumatology, in Boston.
 
A disease caused by abnormalities in the way the brain processes pain signals, FM is characterized by widespread chronic muscle pain. The associated symptoms of FM are fatigue, poor sleep, hypersensitiveness to pressure, memory problems, as well as other mental impairments. Currently, an estimated 5.8 million Americans suffer from fibromyalgia.
 
The strategy the researchers adopted to address the cognitive impairment of FM patients, was to compare the symptoms of FM with the symptoms of rheumatoid arthritis, a chronic inflammatory disease that starts off with pain in the joints followed by joint deformity and finally, immobility of the joints. In addition to the joints RA patients also exhibit significant cognitive impairment.
 
As part of the study, the researchers studied 211 patients of whom 150 were FM patients and the remaining 61 were RA patients. The cognitive functions of both the groups group were assessed by a questionnaire where the severity of the symptoms were rated from scale one (symptoms never occurring) to five (symptoms occurring all the time). Overall, the researchers found that the symptoms of cognitive impairment were worse in FM patients than in the RA patients.
 
Cognitive symptoms in fibromyalgia
 
The researchers observed that a state of clouding of consciousness, termed ‘fibrofog’ (brain fog) is worse in the FM patients than it is in the RA patients. Fibrofog encompasses difficulties using language, difficulties with learning, and memory loss. These symptoms tend to descend in a haze or “fog,” around the sufferer, and hence the name. Both women and men who have fibromyalgia pain, present with fibrofog, though it tends to hit women more often, especially women between the ages of 30 and 50 years. Symptoms of brain fog can range from mild to severe, varying from day to day, and from person to person. The symptoms include:
 
Poor word use & recall: The patient experiences a difficulty in recalling known words, and names and often uses incorrect words in sentences. Short-term memory problems: Forgetfulness, inability to remember what’s read or heard.
 
Directional disorientation: The patient does not recognizing familiar surroundings, and easily loses his way in his own surroundings. They very often also have trouble recalling where regular everyday things are kept.
 
Inability to multitask: More often than not, people with fibromyalgia cannot focus on more than one thing at a time, and tend to forget the original task when distracted with another.
 
Depleted focus: These patients are very often confused and have a lot of trouble in concentrating and processing information.
 
Number difficulties: This is a common feature of people with FM and they find it extremely difficult to perform basic math problems involving addition, subtraction, division etc. The also fail to remember numbers,
 
In addition to the above symptoms, FM patients also have a difficulty with language, including trouble holding conversations, understanding conversations, and expressing thoughts. The often struggle to find the “right” word to use in conversation.
 
People with fibromyalgia are faced with special demands. Given the task of coping with the pain and fatigue each day, patients need to prioritize and adjust their lifestyle according to the demands of fibromyalgia. Having said that, it does not mean you become a slave to the condition. The limitations of fibromyalgia can be lessened if you get the facts. So arm yourself with all the knowledge about the condition, get answers to all your questions and, instead of focusing purely on fibromyalgia, try steering the knowledge seeking process to “fibromyalgia and you”.

I find it very difficult to accept most if not all of these findings of the 150 (FM) subjects.  I was diagnosed in 1999 with FM and later diabetes and other muscular skeletal conditions.  My own doctor specialises in these conditions and obviously my high ranking specialist in RA AND FM and similar conditions. 

In fact the only paragraph I agree with is the last one that summarises how to manage. 

In reading this article I actually thought you'd mixed it up with persons suffering from dementia.

211 people is far to small a collection of people to apply this research of so called symptoms to the millions of people who do actually suffer from FM and RA conditions. 

The cognitive impairment you mention in this research I find very difficult to accept and in my own case so far off the mark. I do suffer from fibrinogen and I can be a little forgetful over unimportant mundane things but my mental capacity is very strong and tests prove that.  

If I did suffer from what is suggested in the paragraphs you write I'd be wanting tests for dementia.

Fibrofog not Fibrinogen.... predictive text is a nuisance.

I find it's the pain meds that give me brainfog, if I haven't slept very well that adds to the muzziness

I have recently been diagnosed with fibromyalga. The pain is awful a lot of the time. I have suffered forgetfulness for some time and have woken up to bruises with know idea how I get them.

I am on new medication but reading the information I am concerned about the affects on internal organs.

It's the constant pain that I hope I get relief from.
