Do psychosocial factors play a role in co-occurring ADHD and fibromyalgia?

An interpretative, mixed-methods study

About the Study

I carried out this study for my dissertation, as the culmination of a two-year masters’ degree into social research methods at the University of Birmingham. Having been given a free choice of topic, I knew it had to be something I was genuinely passionate about, rather than merely to gain a qualification and, therefore, my decision to research the nature of the cooccurrence of ADHD and fibromyalgia was unequivocal!

Although this study was carried out in the realms of ‘social science’ rather than ‘medical science’, I do not believe that psychological or social aspects of either ADHD or fibromyalgia can be studied in isolation, without consideration of how they interact with physical or biological factors. In order to fully understand the nature of a link between the conditions, I would suggest that a holistic approach is necessary.

The study took a ‘mixed methods’ approach, which meant that it had two parts: 1) Survey and 2) Focus group. The aim of the survey was to look for group-level differences between people with ADHD, with or without fibromyalgia, in terms of, for example, their experience of depression and/or anxiety, internalising vs externalising behaviour, ability to talk about emotions, support they had received when growing up, and physical health conditions. The aim of the subsequent focus group was to discuss the findings from the survey in relation to participants’ own experiences.

Part 1: Survey

Group 1 (FM group): 108 participants with ADHD and fibromyalgia (participants with ME or CFS were also included in this group)

Group 2 (non-FM group): 75 participants with ADHD only

  • Ninety-eight percent of participants in both groups had experienced anxiety and / or depression at some point in their lives.

  • Participants in group 1 were significantly more likely to ‘mask how they felt physically’; ie pretend to feel fine when they didn’t.

  • Prevalence of other physical health conditions was higher in group 1, compared to group 2 (see below)

  • Not all participants with fibromyalgia were able to identify a trigger / triggers for the onset of their symptoms. However, emotional stress was the most commonly cited trigger. Other triggers included: physical trauma, illness, and childhood adversity.

  • Participants in group 1 were more likely to report negative experiences with family, teachers and friends in childhood. Participants in group 2 were more likely to report positive experiences.

 
 

Part 2: Focus Group

The focus group consisted of four female participants with ADHD and fibromyalgia and the purpose was to discuss the results of the survey, in relation to participants’ own experiences. Although I did not include my personal experiences of ADHD and fibromyalgia in the data from the focus group when writing up my dissertation, I fully acknowledge how my preconceptions and biases influenced every part of the study, such as how I interacted with participants and my interpretation of the data.  

My research indicated that a particular combination of ‘personality traits’ together with ‘ADHD presentation’, play a role in why a person with ADHD develops fibromyalgia.

Overall, I identified five themes, which I felt were relevant: 1) Personality; 2) Health history; 3) Overlapping symptoms and health conditions; 4) Role of trauma and 5) Impact of ADHD.

Participants’ comments are presented here in italics. Some comments are transcriptions of audio from the Zoom meeting, and others are from typed discussion in the private Facebook group.

 

1: Personality

From the start of the focus group discussions, I observed two areas of similarity in participants’ personality traits. Firstly, participants came across as proactive, determined and driven, with a thirst for knowledge, research, and learning:

 

Constantly striving for answers about our health, with this sort of perfectionist, driven personality, is another source of mental and physical stress, adrenalin and cortisol surging about our bodies as we determine we WILL solve this problem and find answers! (F)

 

…the fibromyalgia sent me into a ‘typical’ ADHD hyper-focus research mission. When the consultant said “let’s not worry about what caused it let just treat the symptoms” my scientist mind was like well that’s the most ridiculous statement I’ve ever heard. (T)

 

…her hyperfocus (and mine with work) will mean that we plough on past the point it would [be] a healthy place to stop thereby exacerbating an already exhausted mind/body. My daughter will swim just because she’s set herself a goal (e.g. this summer it was 100 lengths before she’d get out of the pool – she was 9). (L)

Secondly, participants appeared to have similar ADHD profiles as they all described how they would ‘mask’ both their ADHD traits and fibromyalgia in order to fit in and please others:

 

My mouth has said what I think others need to hear before my brain is even aware. (B)

 

Since my diagnosis I notice I really work hard to mask my ADHD tendencies in work meetings. It is exhausting. (T)

 

When I say I ‘mask physical symptoms’ I’m thinking of how I “hold it all in” – it feels like I hold my muscles tense to try and stay still, when I would otherwise want to be fidgeting or moving about because of ADHD inability to be still and because fibromyalgia muscle pain/tension makes me want to do “weird” looking exercises and stretches. Also pushing on and doing things I know are going to cause me (more) pain and fatigue. (F)

 

However, participants described their relatives who have ADHD, but not fibromyalgia, as having very different ADHD profiles:

 

…my sister’s got ADHD… erm… but her ADHD presented much differently… she is much more typically…erm… quite erm… she’s a bit more aggressive she’s a bit more… she doesn’t try and please anybody she’s like… she… she’s much more what you would… some people would feel is stereotypically ADHD…(B)

Although my sister is, I theorize, more "fawn" than "fight or flight" and therefore maybe doesn't have the muscle tension I do, she is NOT laid back and relaxed! I think somehow my "fight or flight" in part makes me/is caused by me, standing up for myself, and learning to be more assertive and set boundaries and all that, versus my sister letting people manipulate her and do emotional blackmail on her, and she has lower self-esteem than me. (F)

2: Health history

All of the participants reported that, before their fibromyalgia diagnoses, they had had health issues, such as muscle tension, joint pain and stomach problems:

…I’ve had the FM diagnosis for about 10 years, but as is often the way with these things, obviously there’s a lifelong story leading up to that of other problems before I got that far. (F)

 

I’ve had unexplainable pain stuff since probably 2000. Stomach issues all my life. (B)

 

My fibromyalgia was diagnosed in my early 20’s after a childhood of general malaise, huge amounts of antibiotics due to kidney problems and then EBV/CFS at 19. (L)

 

…I’ve always had really bad muscle tension [unintelligible]… pain… I’ve got some lower back problems, but I was fairly healthy. I would get a stiff neck, kind of come and go… (T)

4: Role of trauma

Trauma is often cited as a trigger for fibromyalgia, and people with ADHD are reported as being more at risk of trauma. However, not all people with ADHD who experience trauma, will go on to develop fibromyalgia. Furthermore, people with ADHD who have not experienced trauma, can also develop fibromyalgia.

One focus group participant shared details of a particular traumatic incident which triggered her fibromyalgia. However, other participants discussed how they felt that undiagnosed ADHD and the struggle of coping with ‘everyday life as a neurodivergent in a neurotypical world’ (F), had triggered their fibromyalgia:

Through the slow process over the years of learning to speak up for myself and aiming to be a “more authentic” version of myself for the sake of my own self-respect and peace of mind, with […] and some friends, I have unmasked about the physical pain and fatigue of fibromyalgia… (F)

The journey my health has taken me on has made me begin to question if years of living with ADHD, when it wasn't a thing, so no support, has caused my other issues. The Dr who diagnosed me with dysautonomia seemed to think this was very likely. So, for me, masking the ADHD caused my other issues. (B)

Early stress in human development could alter stress mechanisms, leading to increased vulnerability to stress-related disorders. As such, lengthy trauma or life stress in childhood and adulthood seems to negatively affect brain modulatory systems, of both pain and emotions (Galvez-Sánchez et al., 2019):

 

Early life stressors or severe and prolonged stress effectively predicts the development of chronic and severe pain. Psychological distress has a strong aetiological influence on chronic widespread pain (Gupta et al., 2006).

3: Overlapping symptoms and health conditions

Alongside their fibromyalgia, all but one participant reported other diagnoses, which meant that it was not always clear which condition caused which symptom:

They say you get those kind of ‘muddly’ things… like I can’t quite say for sure anymore what’s fibromyalgia symptoms and what’s something else and… uh… fibromyalgia in itself is a very broad title that covers many things… (F)

Two participants had been diagnosed with hypothyroidism (underactive thyroid) and one also had a diagnosis of dysautonomia:

I have also been diagnosed with dysautonomia […]. Then on top I have underactive thyroid and menopausal. So I can’t explain the link between symptoms as I don’t know which of my disorders is causing what and when. It’s very confusing and frustrating. (B)

In addition, hormones impacted on participants’ fibromyalgia, as well as their ADHD:

…on my period today and it’s no matter what I do… no matter what strategies I put in place… the week leading up to my period or on my period my symptoms are so much worse… everything… it’s like yeah… pain, fatigue and my stomach is worse… (T)

 

I can’t focus and my ADHD gets worse as well like work… the week leading up to my period at work… I might as well not be there… I’m so unproductive… (T)

 

I’ve… definitely deteriorated… due to peri-menopause… um… noticeable deterioration in… or… increase in all symptoms… (F)

One participant also felt that there was overlap between her autism and fibromyalgia:

Some symptoms I vaguely thought were part of fibromyalgia, I now have different diagnoses for, for example sensory sensitivities. I put that down to fibromyalgia, but now I have a separate diagnosis of Sensory Integration Dysfunction as an off shoot of Autism. (F)

5: Impact of ADHD

The final theme that emerged from the discussions was how ADHD traits impacted on participants’ fibromyalgia:

 

When my brain is being under-stimulated, I think my fibro type symptoms kick in even more so. (L)

…we haven’t got the alarm in our own mind to say… ‘you’re going to pay for this tomorrow you need to just chill a bit’ until it’s too late, I think… I think that’s a real downside for us… (B)

 

In fact, an ‘overactive lifestyle’ and ‘high action proneness’ (which means ‘a cognitive and behavioural tendency towards direct action’), have been cited as common pre-morbidities in CFS and fibromyalgia patients (Van Houdenhove et al., 2001, 2006) and as ‘predisposing, initiating and maintaining factor of chronic pain’ in people with fibromyalgia (Baeza-Velasco et al., 2018, p.167). Participants’ descriptions reflect the difficult balance described by Radley (1994) of being perceived either as ‘too reckless’ if they try to press on as normal, or as malingerers if they take care of themselves (Varul, 2010):

 

It doesn’t matter how many times you tell me… I understand the theory, but I’m totally incapable of doing it, and of course if the person talking to you doesn’t know anything about ADHD, they just think you’re not trying hard enough… like… ‘you’ve been told what to do and you’re not doing it I can’t help you…’ (F)

 

…everything says the same thing about how you should manage this but… I can’t stick to a routine long enough… (T)

 

Participants felt that strategies, which were recommended for people with fibromyalgia, were impossible for participants to stick to, which led to feelings of frustration:

So yeah… um… the main… the main… um… strategy I was told for fibromyalgia is pacing yourself, which is just like an ADHD nightmare. It’s like completely incompatible… (F)

…all the mindful stuff… there’s so much mindful stuff… mindfulness stuff out there at the minute and… you know… I can’t do it! I just can’t…” (B)

Summary of findings - what does it all mean?

 

Fibromyalgia is thought to be triggered by stress / trauma. The strongest evidence for the nature of fibromyalgia seems to be that it is an immune system disorder, which makes sense because of the impact that stress can have on the immune system.

People with ADHD have a higher risk for stress and trauma (compared to the general population), which might explain why they also have a higher prevalence of fibromyalgia. However, as not all people with ADHD who experience stress or trauma develop fibromyalgia, there must be other factors involved.

My study led me to tentatively conclude that 'personality' and 'ADHD profile' are important mediating factors between the conditions. I base this on observed similarities within the focus group participants, as well as their descriptions of their family members who had ADHD but without fibromyalgia.

Focus group participants described themselves as driven, perfectionist, determined etc. All seemed to have a thirst for knowledge and research, e.g. needing to know everything about a topic (such as their fibromyalgia!). However, they also described how they inhibited, masked and suppressed their ADHD traits (inner hyperactivity / restlessness) in order to fit in.

Conversely, family members with ADHD but not fibromyalgia, were described differently, such as 'more stereotypically ADHD', or 'more laid back and easily manipulated'.

I realise, of course, that I am basing my assumptions on a very small group of people. However, the 'personality profile' that I observed also fits with the descriptions of people (mainly females) with fibromyalgia from other research studies e.g. 'high action proneness' and 'perfectionist'. Whilst these studies don't mention ADHD, they describe many ADHD traits.

Obviously, more evidence is needed to come to a firm conclusion, and I am looking into doing this in the near future. I also plan to add links to the research on everything I have mentioned (such as the impact of stress on the immune system and the fibromyalgia personality profile).
