Fibro fog – also known as fibromyalgia fog and
brain fog – is a term commonly used for the cognitive difficulties that can
occur with fibromyalgia.
According to a 2015 review in Rheumatology International, some patients report that the loss of mental clarity can be even more devastating than the pain and fatigue associated with fibromyalgia. Fibro fog can manifest itself in different ways in different people but some of the most common symptoms include:
According to a 2015 review in Rheumatology International, some patients report that the loss of mental clarity can be even more devastating than the pain and fatigue associated with fibromyalgia. Fibro fog can manifest itself in different ways in different people but some of the most common symptoms include:
·
short term memory loss
·
misplacing objects
·
becoming easily distracted
·
forgetting plans
·
difficulty carrying on conversations
·
inability to remember new information
Although cognitive difficulties have sometimes been thought of
as “all in a patient’s head,” a 2015 study in Fibro Care and Research found that fibro fog is a real issue.
In a study of 60 individuals – 30 with fibromyalgia and 30 without
fibromyalgia – researchers found various impairments of attention and
memory in fibromyalgia patients when compared with healthy controls. What remains
unclear is what is causing the cognitive challenges.
Sleep Better, Feel Better
Though the cause of fibromyalgia fog is still up for debate,
many physicians and researchers theorize that fibro fog could be related to poor sleep.
“The
first thing I ask my patients is how well they’re sleeping,” says Dr. Keenan.
“Most will tell me that they’re waking up several times during the night or
lying awake for hours. Goal number one becomes getting them to sleep well,
which can help them feel sharper, as well as help them better deal with pain.”
Dr.
Keenan often tackles sleep issues using a combination of tactics.
“I often prescribe patients amitriptyline (Elavil), which
helps people reach the level of restorative sleep they’re often missing with
fibromyalgia,” says Dr. Keenan. “I also recommend that they get as much
activity during the day as they can handle, whether it’s walking 50 feet down
the street or getting into a warm pool to exercise. Good sleep hygiene also is
important.”
Is the Brain to Blame?
Though
better sleep has many benefits, some studies show there are simply different
things happening in the brains of people with fibromyalgia. In one study, brain
scans showed that from time to time, people with fibromyalgia do not receive
enough oxygen in different parts of their brain. One possible reason is that
part of their nervous system is off-kilter, causing changes in the brain’s
blood vessels.
Additional research – though not on fibromyalgia specifically –
showed that chronic pain may affect the brain. Functional MRI found that in
people with chronic pain, a
front region of the brain mostly associated with emotion is constantly active.
The affected areas fail to shut off when they should, exhausting neurons and
disturbing the balance of the brain as a whole.
A 2013 review in Current Pain and Headache
Reports on
cognitive impairment in fibromyalgia patients confirmed that the jury is still
out on the exact cause of fibro fog. However, it did report that patients may
see some cognitive improvement with a combination of physical activity,
cognitive-behavioral therapy and medication.
