Post hoc analysis showed that NP25 amplitudes were higher in patients with MOH and migraineurs without aura studied ictally than in the subgroup studied interictally and controls. Post hoc analysis disclosed smaller NP25 amplitudes in patients overusing triptans than in those overusing NSAIDs or both medications combined. In addition, group analysis between triptan overusers and controls showed that the NP Pearson's test disclosed various correlations between SEP amplitude and clinical variables.
The distinct changes we found in cortical responses to low and high numbers of sensory stimuli in patients with MOH suggest that the underlying brain mechanisms are altered and differ from those acting in patients with episodic migraine without aura. Low numbers of. In MOH patients, SEP amplitude was lowest in those with the longest history of migraine, whereas it was highest in those with the longest period of headache chronification, suggesting that the electrophysiologic changes reflect chronification.
Patients who overused triptans had lower SEP amplitudes than those who overused NSAIDs or both anti-migraine medications combined, indicating that sensitization varies according to the drug overused. The combination of an initial SEP amplitude increase sensitization along with the subsequent lack of habi-tuation suggests that the electrophysiological pattern underlying MOH differs from that underlying episodic migraine.
In episodic migraine, SEP recordings show two characteristic changes: a lack of habituation on interictal recordings, and sensitization during the attack. The habituation deficit normalizes during attacks, whereas sensitization disappears between attacks, but in the immediate pre-ictal phase both sensitization and.
The electrophy-siological pattern we found in MOH may therefore suggest that the sensory cortex is locked in a pre-ictal state associating both hyper-sensitivity due to sensitization and hyper-responsiveness due to deficient habituation , which contrasts with episodic migraine where these cortical states alternate. It is likely that the disclosure of this peculiar electrophysiological pattern was made possible by the fact that we avoided to record MOH patients during a full-blown migraine attack.
The SEP pattern associating sensitization and lack of habituation that we compared with a "persistent pre-ictal state", closely resembles the response patterns generated by central sensitized neuronal circuits. Sensitization refers to a facilitatory process that competes with its opposite, habituation to determine the final behavioural outcome after stimulus repetition.
This has been called the "dual process" theory [15,16]. Illustrative of central sensitiza-tion are the plastic changes in neural structures belonging to the "pain matrix" [19] that result in decreased nociceptive thresholds and increased responsiveness to noxious and innocuous peripheral stimuli [20]. Studies in animals [21] and humans [22] show that SEP amplitudes increase when transient intense activation of noci-ceptive afferents induces central sensitization, as.
Our study shows that sensitization, as reflected by increased initial SEP amplitudes, is common to MOH and migraine attacks, although we did not record MOH patients during an attack.
A clinical consequence of central sensitization is cutaneous allodynia. It was shown to be prevalent during episodic migraine attacks at cephalic and extracephalic sites [23,24], but even more so in chronic migraine [25]. It is associated with increased nociceptive reflexes [26,27], but, interestingly, in MOH trigeminal evoked potentials were increased, whereas nociceptive blink reflexes remained unchanged, suggesting as in our study that sensitization takes place at supraspinal levels [28].
Our finding that the SEP amplitude increase in MOH is proportional to the duration of headache chronifica-tion suggests that medication overuse and increased headache frequency promote or reinforce central sensiti-zation, but leaves open the question of the culprit.
Conversely, since total duration of the migraine disorder correlates inversely with SEP amplitudes, the SEP amplitude increase is likely related to factors other than migraine duration and simply repetition of attacks.
The neurobiological underpinning for this difference remains to be determined. An observation that might favour of NSAIDs consumption as a factor promoting sensitization is that NSAIDs increase spinal expression of inducible cyclo-oxygenase-2 [29], an enzyme that contributes to sensitization in a rat model of inflammatory pain [30].
Another possible link between central sensitization, migraine and anti-migraine drugs is monoaminergic transmission in the central nervous system CNS. Between attacks, migraine patients have low blood 5-HT levels whereas the reverse is true ictally [31].
Serotonin synthesis in the brain increases during attacks, and this increase is partly counteracted by acute triptan treatment [32]. Chronic administration of triptans in rats, however, increases 5-HT synthesis in several cortical projection areas of the dorsal raphe nucleus [33] possibly reflecting down-regulation or desensitization of 5-HT1 receptors. By contrast, in rats chronically treated with analgesics, 5-HT2A receptors are down-regulated [34] and the 5-HT transporter is up-regulated in the cortex [34] and in platelets [35].
Upregulated platelet 5-HT transporters [35] and decreased whole blood 5-HT levels [36] tend to. Collectively, these experimental data suggest that anti-migraine drug overuse can disrupt central 5-HT transmission. In chronic triptan overuse both pre- and postsynaptic 5-HT1 receptors may become desensitised with the ensuing net effect that serotonergic transmission may be only mildly impaired.
During analgesic and NSAID overuse, however, the combination of receptor desensitisation and transporter upregulation may lead to serotonergic hypoactivity. Together with noradrenaline and dopa-mine, serotonin is crucial for tuning cortical excitability including sensitization and habituation processes and its effect in animals varies with concentration and duration of application [37].
Whether the difference between the drug classes with regard to central sensitisation is related to the clinical observation that withdrawal headache is much shorter after triptan than after analgesic overuse [38] remains to be determined in a properly designed prospective study comparing clinical outcome and elec-trophysiological patterns. The association of electrophysiological sensitisation, i.
It is at odds with the electrophysiological pattern associating high amplitude in 1st block and normal habi-tuation found during migraine attacks [], but, as mentioned before, it has been described in the pre-ictal phase []. One possible explanation for the lack of habituation in episodic migraineurs between attacks is the "ceiling theory" [39] postulating that there is a low preactivation level of sensory cortices, also responsible for the low 1st block amplitudes, would allow a larger range of activation before habituation occurs [6,8].
The habituation deficit in NSAIDs overusers cannot be explained by the "ceiling theory" since their high 1st block amplitude indicates rather that the somatosensory cortex is sensitised.
There is at present no straight forward explanation for this pattern. It is likely, however, that other neurobiological mechanisms that participate in the production of habituation are impaired. For instance, inhibitory interneurons could be hypofunctioning because of the reduction in serotonergic transmission induced by the prolonged NSAID overconsumption.
This hypothesis can be tested experimentally by searching if habituation normalizes during full-blown attacks in MOH patients like in episodic migraine and by exploring inhibitory cortical interneurons with dedicated neurophy-siological studies such as that of cortical silent periods using transcranial magnetic stimulation.
Given the similar neural mechanisms underlying sensory and behavioural sensitization [40], the interesting question arises. Behavioural sensitiza-tion is paradigmatic of how the serotonergic, dopaminer-gic, and noradrenergic systems interact and contribute to central sensitization [41]. Brain circuits involved in addictive behaviour include ventral and dorsal striatum, amygdala and orbitofrontal cortex and are heavily modulated by dopaminergic projections from the ventral tegmental area of the midbrain, serotonergic projections from the median and dorsal raphe nuclei, and noradrenergic projections from the locus coeruleus [4,42].
The latter has been associated with orbito-frontal cortex hypoactivity [44], an abnormality also found in subgroups of MOH patients [5]. The orbito-frontal cortex is thought to modulate habituation mechanisms [45] and orbito-frontal lesions induce SEP sensitization and lack of habituation [46], precisely the two sensory abnormalities we found in patients with MOH.
Our findings along with current knowledge on the neurobiology of drug overuse therefore suggest that future studies seeking correlations between electrophy-siological and metabolic measures should focus on the orbito-frontal cortex.
In our study we did not control for associated depression and anxiety. Despite the evidence that cortical pain-related evoked potentials in MOH do not differ between subgroups of patients with or without depressive symptoms [28], it may still be appropriate to control for psychiatric comorbidity in future studies. Cortical responses to repetitive sensory stimuli are abnormal in patients with MOH.
Increased response amplitudes after low numbers of stimuli indicate sensory sensitization and lack of amplitude decrease during subsequent stimulations reflects a habituation deficit. This cortical response pattern is similar the one found in the immediate pre-ictal phase in episodic migraine, but different from the interictal and ictal patterns. It suggests that the somatosensory cortex has become persistently sensitized and that the migraine generating mechanisms in the central nervous system are not shut off.
The sen-sitization is obvious in patients overusing NSAIDs and almost non-existent or masked in those who overuse only triptans. The different electrophysiological pattern between drug classes may be related to the clinical observation that withdrawal headache is shorter lasting in triptan overusers than in NSAID overusers. We postulate that the abnormal sensory processing in MOH patients reflects a drug-induced impairment of central serotonin neurotransmission, that the decrease of sero-tonergic activity is more profound after chronic NSAID overconsumption and that the cortical sensory sensitization parallels the behavioural sensitization that.

The proportion of female adults with osteoporosis increased considerably with age; the prevalence of osteoporosis for men remained nearly unchanged until the age of 84 years Fig. Regarding the level of education, people with a low educational level showed higher prevalence rates of osteoporosis compared to those with a higher educational level.
Overweight or obese adults had smaller prevalence rates than people with a BMI within the normal range. The prevalence of osteoporosis was higher for non-smokers in comparison to ex- and current smokers and participants with a moderate or high consumption of alcohol showed lower rates than respondents that stated to never drink alcohol Table 1.
Age, sex, alcohol consumption and BMI showed a significant association with the odds for osteoporosis. The odds of having osteoporosis were higher for female adults than male adults. Using 50 - 54 years old adults as reference, the odds for osteoporosis increased with age. Overweight or obese adults were associated with lower odds for osteoporosis in comparison to adults with normal weight Table 1.
For adults without osteoporosis, only As illustrated in Table 2 , arthrosis About one in every five adults with osteoporosis suffered from coronary heart disease In line with this, hypertension A separate regression model was fitted for each comorbidity.
Eleven out of fifteen comorbidities showed a significant association with osteoporosis. Of note, for adults with osteoporosis, the odds for arthrosis, chronic low back pain, arthritis, depression and chronic heart failure, respectively, were more than two times greater than for adults without osteoporosis Table 2. Sex-stratified analyses as well as analyses restricted to participants with valid data on all independent variables in regression complete cases showed similar results to the main analysis data not presented.
The underlying study provides representative data on prevalence rates and comorbidities of osteoporosis based on the German population aged 50 years and older. The overall prevalence was estimated to 8. According to multiple regression analysis, osteoporosis was significantly related to age, sex, BMI and alcohol consumption while smoking status and education showed no significant association. Adults with osteoporosis showed more than twofold increased odds for arthrosis, arthritis, chronic low back pain, chronic heart failure and depression, respectively.
However, our results agree well with those of other studies on osteoporosis [ 27 — 32 ]. In comparison to other German studies [ 29 — 32 ], results on prevalence rates vary with regard to the methodology of measuring osteoporosis as well. Similar to GEDA , DEGS1 provides nationally representative data on the health status of the adult population between 18 and 79 years of age and estimated a lifetime prevalence of osteoporosis self-reported for people aged between 50 and 79 years to 8.
Little differences with regard to socioeconomic status and an association with age for women were reported, too [ 29 ]. On the other hand, considering a study based on routine data of a statutory health insurance, prevalence rates were found to be higher. Deviating methodical procedures might be responsible for differences in prevalence. Results of studies examining the relationship between smoking and osteoporosis as well as alcohol consumption and osteoporosis including low BMD and fracture risk are inconsistent [ 33 — 37 ].
There was also no clear evidence of a relationship between osteoporosis and smoking in the present study. While the prevalence of osteoporosis was significantly lower for higher educated adults in comparison to adults with a low educational level, results of the present regression analysis revealed no significant effects.
Prevalence rates may be biased as a consequence of misclassification as our results are based on self-reported diagnoses that were not clinically verified. Since osteoporosis is not associated with any symptoms prior to a fracture and information on possible fractures were not available within GEDA, prevalence rates may be underestimated by not taking account of yet undiagnosed adults.
On the other hand, considering arthritis, for example, prevalence rates may be overestimated as it is known that patients with other joint disorders often falsely state to suffer from rheumatoid arthritis [ 20 , 39 ]. Using self-reported information on sociodemographic characteristics such as BMI values may lead to biased estimates as well reporting bias.
Moreover, only adults living in private households were contacted, hospitalized adults or adults living in care homes could not be considered. As all interviews were carried out in German, adults had to speak and understand German, thus marginalized groups such as migrants could not be regarded [ 20 ]. Low-level educated adults agreed less often to participate in the telephone interview than people with a medium or high level of education [ 20 ].
A weighting factor provided by the Robert Koch Institute was used to approach the adult residential population structure in Germany [ 20 ]. Osteoporosis represents a major public health concern and its prevention is crucial to the maintenance of health [ 40 ].
It is a systemic condition characterized by changes in bone microarchitecture and a reduction of bone mass, both of which lead to decreased bone strength and at the same time to increased fracture risks. As a consequence, treatment at all ages aims at retaining bone mass to prevent any type of fracture e. Fractures with severe complications are serious consequences of osteoporosis that have an influence on morbidity, functional impairment of health, a decrease in quality of life as well as an increase in medical costs [ 40 , 41 ].
Additionally, at the time of a fracture, comorbidities in osteoporosis patients play a key role. Further, drug-drug interactions may affect the progress of the disease. Regarding osteoporosis, especially the consumption of drugs that have an effect on bone metabolism is of interest. In GEDA however, data on the use of pharmaceuticals were not collected and an evaluation of the use of different drug classes could therefore not be done.
In the present study nearly all adults with osteoporosis reported at least one comorbid condition, but the cross-sectional design did not allow for an analysis of cause and effect. In the GEDA study population participants that stated to suffer from osteoporosis were for example more than twice as likely to also suffer from depression.
Drosselmeyer et al. Physical disability following fractures affects the capacity for independent living and complicates social participation. Besides, as physical activity is reduced in depressive patients but important to improve or at least stabilize bone mineral density, it would be important to recognize and treat the disease early. Of interest is also the association between arthrosis and osteoporosis. In the present study, participants with osteoporosis showed more than three times higher odds of having arthrosis.
However, in most cross-sectional studies [ 43 ], arthrosis was negatively connected with osteoporosis in the sense that people with arthrosis showed higher BMD.
Despite this negative association, the risk of osteoporotic fractures in patients with arthrosis remains the same [ 43 ]. Generally, arthrosis is associated with stiffness and pain in the affected joints, and this may reduce physical activity, which subsequently leads to instability and higher fracture risks.
Hence, the relation of osteoporosis and arthrosis appears to be very complex and needs to be analysed further. The disease burden in adults with osteoporosis is of high relevance. Physicians need to be aware of the high occurrence of multimorbidity in adults with osteoporosis.
Health care interventions for affected patients should be expanded by offering early or even preventive care for other diseases that go along with it.
