Background Our recent studies have shown headache disorders to be very common in the central and western sub-Saharan countries of Benin and Cameroon. Here we report headache in nearby Mali, a strife-torn country that differs topographically, culturally, politically and economically. The purposes were to estimate headache-attributed burden and need for headache care. Methods We used cluster-random sampling in seven of Mali’s eleven regions to obtain a nationally representative sample. During unannounced household visits by trained interviewers, one randomly selected adult member (18–65 years) from each household was interviewed using the structured HARDSHIP questionnaire, with enquiries into headache in the last year and, additionally, headache yesterday (HY). Headache on ≥ 15 days/month (H15+) was diagnosed as probable medication-overuse headache (pMOH) when associated with acute medication use on ≥ 15 days/month, and as “other H15+” when not. Episodic headache (on < 15 days/month) was recorded as such and not further diagnosed. Burden was assessed as impaired participation (days lost from paid and household work, and from leisure activity). Need for headache care was defined by criteria for expectation of benefit. Results Data collection coincided with the SARS-CoV-2 pandemic. The participating proportion was nonetheless extremely high (99.4%). The observed 1-year prevalence of any headache was 90.9%. Age- and gender-adjusted estimates were 86.3% for episodic headache, 1.4% for pMOH and 3.1% for other H15+. HY was reported by 16.8% with a mean duration of 8.7 h. Overall mean headache frequency was 3.5 days/month. Participants with pMOH lost more days from paid (8.8 days/3 months) and household work (10.3 days/3 months) than those with other H15+ (3.1 and 2.8 days/3 months) or episodic headache (1.2 and 0.9 days/3 months). At population level, 3.6–5.8% of all time was spent with headache, which led to a 3.6% decrease in all activity (impaired participation). Almost a quarter (23.4%) of Mali’s adult population need headache care. Conclusion Headache is very common in Mali, as in its near neighbours, Benin and Cameroon, and associated with substantial losses of health and productivity. Need for headache care is high – a challenge for a low-income country – but lost productivity probably translates into lost gross domestic product.

Diabetic polyneuropathy (DPN) with or without neuropathic pain is a frequent complication of diabetes. This work aimed to determine the prevalence of diabetic polyneuropathy, to describe its epidemiological aspects, and to analyze the therapeutic itinerary of patients with DPN. This was a cross-sectional, descriptive study performed synchronously over six months at two major follow-up sites for patients with diabetes in Mali. DPN was diagnosed based on the Michigan Neuropathy Screening Instrument (MNSI). The neuropathic nature of the pain and the quality of life of patients were evaluated by the DN4 and the ED-5D scale, respectively. We used three (3) different questionnaires to collect data from patients (one at inclusion and another during the follow-up consultation) and from the caregivers of patients with DPN. We included 252 patients with diabetes, and DPN was found to have a healthcare facility-based prevalence of 69.8% (176/252). The sex ratio was approximately three females for every male patient. The patients were mostly 31 to 60 years of age, 83% had type 2 diabetes, and 86.9% had neuropathic pain Approximately half of the patients (48.3%) had autonomic neuropathy and they reported moderate to intense pain, which was mainly described as a burning sensation. The patients exhibited impaired exteroceptive and proprioceptive sensations in 51.7% of cases. The patients smoked tobacco in 3.4% of cases, while 36.6% of the patients were obese and had dyslipidemia. The caregivers clearly indicated that appropriate medications were not readily accessible or available for their patients with DPN. The healthcare facility-based prevalence of DPN with or without neuropathic pain was high in our cohort. These inexpensive and easy-to-use tools (MNSI, DN4) can be used to adequately diagnose DPN in the African context. In Mali, screening and early treatment of patients at risk of DPN should allow for a reduction of the burden of the disease, while caregivers need to be adequately trained to manage DPN.

Introduction Neurological disorders (ND) have a high incidence in sub-Saharan Africa (SSA). In this region, systemic challenges of conventional medicine (CM) and cultural beliefs have contributed to a large utilization of traditional medicine (TM). Yet, data on TM and those who use it in the treatment of ND in SSA are scarce. Here, we systematically analyze its role as a therapy modality for ND in Mali, the socio-demographic characteristics of its users, and propose next steps to optimize the dual usages of TM and CM for patients with ND. Methods We conducted a questionnaire study in two phases. In phase one, patients with ND answered questions on their usage of and attitudes towards TM. In phase two, the TM therapists who provided care to the patients in phase one answered questions regarding their own practices for treating ND. Patients were recruited from the country's two university neurology departments. Results 3,534 of the 4,532 patients seen in the Departments of Neurology in 2019 met the inclusion criteria. Among these 3,534 patients, 2,430 (68.8%) had previously consulted TM for their present ND. Patients over 60 years of age most often used TM (83.1%). By education, illiterate patients utilized TM the most (85.5%) while those with more than a secondary education used TM the least (48.6%). An income greater than the minimum guaranteed salary was associated with decreased use of traditional medicine (OR 0.29, CI 0.25–0.35, p  < 0.001). Among those using TM, it was overwhelmingly thought to be more effective than CM (84.6%). Linking illness to supernatural causes and believing TM therapists had a better understanding of illnesses were the most common reasons patients used traditional medicine (82.3% and 80.5%, respectively). We then interviewed 171 TM therapists who had provided care to the patients in phase one. These providers most commonly “sometimes” (62.6%) referred patients to CM and 4.1% never had. A majority of TM providers (62.6%) believed collaboration with CM could be improved by having doctor “take into account” our existence. Conclusion Our work shows that TM plays a central role in the provision of care for patients with ND in SSA with certain cohorts using it at higher rates. Future development of treatment of ND in SSA will require optimizing TM with CM and needs buy-in from all stakeholders including conventional medicine clinicians, traditional medicine therapists, researchers, politicians, and most importantly, patients.
