Migraine diagnoses positively associated with dementia
A few studies focused on the association between other headaches, migraine headaches and dementia, found a positive migraine-dementia relationship.
This study was based on data from the Disease Analyzer database (IQVIA), which compiles drug prescription, diagnoses and basic medical and demographic data obtained directly and in anonymous format from computer systems used in the practices of general practitioners and specialists.
The current study smaple included patients who had received a migraine diagnosis in one of 67 general practices in the UK. Patients without migraine diagnoses were matched 1:1 to patients with migraine diagnoses based on propensity scores using a greedy algorithm and derived from the logistic regression using age, sex, index year and co-diagnoses ( i.e. diabetes mellitus, hyperlipidemia, coronary heart disease, stroke including transient ischemic attack, depression, intracranial injury, mental and behavioral disorders due to alcohol use, epilepsy, Parkinson's disease, osteoporosis).
The index date for participants without migraine diagnoses was randomly selected visit between Jan. 1997 and Dec. 2016. The main outcome of the study was the incidence of dementia as a function of migraine diagnosis within 10 years of the index date.
The present study included 3,727 individuals with 3, 727 individuals without a migraine diagnosis. However, a positive association between migraine diagnoses and all-cause dementia and Alzheimer's disease was only significant in women ( Hazard Ratio (HR): 1.65; Alzheimer's disease:HR= 2.27), not in men.
Several biological and clinical hypotheses may explain the association between migraine headaches and dementia. For e.g., migraine headaches involve chronic pain, which has been found to substantially impact the risk of memory decline and dementia. As women usually have more severe migraine attacks, the risk of dementia in women with migraine could be higher than in men with migraine explained a Dr.
We've conducted several studies focused on dementia in recent years. We've been able to identify positive associations between osteoporosis and dementia and between epilepsy and dementia, but have also observed the negative association between some antiepileptic, antidepressant and antihypertensive drugs and dementia incidence. Such findings demonstrate the significant role of anonymous patient data in epidemiology research for helping people recognise and avoid health risk factors in the future, noted a Prof.
The authors of the study also noted that further studies are warranted to gain a better understanding of the underlying mechanisms of the migraine-dementia relationship and the different sexes in the association between migraine and dementia.
The 3 major strengths of this study are a large number of patients available for analysis, the use of real-world data including several comorbidities, and the matched-pair design.
However, this study also has 2 major limitations. Although the prevalence of migraine headaches is the highest in young adults and tends to decrease with age, this study only included participants aged between 60 and 8- years, thus potentially introducing a bias into the statistical analyses.
