Psychosocial Factors Are Not Instrumental
For decades, studies focusing on personality and psychological profiles of those with migraine have dominated journals. The end result suggests that depression and anxiety is increased among migraineurs,1 and a strong correlation between pathological personality and migraine.2
I was intrigued and bemused by a recent study demonstrating that those with migraine (n=162) compared to controls (n=140) were less optimistic and more pessimistic, and confirmed higher levels of anxiety and depression (yet again!). Pessimism and anxiety predicted migraine, whilst optimism was inversely associated migraine related disability.3
This is hardly ground breaking research, but it is interesting to note that another study investigating personality profiles of 124 patients with migraine and 77 controls found that of all the (many) personality traits assessed, anxiety and depression were the primary psychological aspects of migraine.4 However, whilst anxiety and depression was twice that of controls, they were not the personality trait facets primarily influencing migraine.,4 i.e. not inherent in the ‘migraine personality’.
Sensitisation of the trigemino cervical nucleus is the underlying disorder in Migraine, indeed Primary Headache and chronicity in headache generally.5-10 Research demonstrates that biopsychosocial factors are not the main factors responsible for central hyper-excitability i.e., spinal cord hyper-excitability appears to not be affected, at least significantly, by psychological factors.11
Despite this context, debate continues as to whether psychological distress precedes and causes chronic pain or, conversely, psychological distress is a consequence of chronic pain.12
Interestingly, a recent study has questioned the role of early attention to biopsychosocial factors in low back pain. Two hundred and two patients underwent:
i) treatment for acute low back pain
and either a
ii) session comprising information on pain and biopsychosocial contributors plus self-management techniques, such as remaining active and pacing
iii) a placebo education (active listening, without information or advice) session.
The authors concluded… ‘Adding 2 hours of patient education to recommended first-line care for patients with acute low back pain did not improve pain outcomes. Clinical guideline recommendations to provide complex and intensive support to high-risk patients with acute low back pain may have been premature.’13
Recognising extrapolation from acute lower back pain to chronic headache may be tenuous, the literature14 (and clinical experience) suggests that it is detrimental to focus on psychosocial factors in chronic headache; changing patients’ pain by identifying and successful intervention of relevant biomedical sources is the most powerful instrument in effecting changes in psychosocial environments.15
The evidence suggests that psychosocial factors are not instrumental in the outcomes of chronic headache patients. Therefore, whilst it is recognised that psychological, behavioural, and lifestyle factors may influence a physical disorder in chronic headache patients at various times,16 identifying and managing relevant biomedical disorders should be, and is the focus, thus ensuring the provision of a committed service.12
Here’s to changing psychosocial situations ‘bottom up’ by raising the awareness of (and addressing) noxious cervical afferents!
