Yoruba categories for mental disturbance, what traditional treatment consists of including the restraint that is its worst feature, Lambo's village system at Abeokuta and why it changed community psychiatry worldwide, and the trial evidence on collaboration with healers.
The Yorùbá wey dem quote, the proverbs, oríkì, ẹsẹ Ifá, word list headwords, Odù names and citations dey exactly as the corpus record dem, for every language.
Two things dey wey person must talk for the start of any account about Yoruba mental health care, and most accounts dey talk only one.
The first one na say Yoruba psychiatry bring out one of the very important innovations for twentieth-century mental health care. Thomas Adeoye Lambo village system for Aro, Abẹ́òkúta, treat psychiatric patients for normal villages with their family present instead of asylum, and e do am from the mid-1950s, decades before deinstitutionalisation come turn standard practice for Europe and North America. No be just heritage claim. Na documented institutional history wey get international influence.
The second one na say traditional and faith healing centres for Nigeria dey chain people. Human Rights Watch find out say dem chain or tie people with iron for 27 out of 28 facilities wey dem visit across the country for 2018 and 2019, and the youngest person wey dem chain na one ten-year-old boy . Dis one na current human rights abuse, no be cultural practice wey deserve neutral description, and any account wey drop am no dey really describe the matter.
The two of dem na true. The rest of dis file hold both of dem together.
Dis categories no be translation of DSM categories and person no suppose force dem enter inside am. The best documentation come from the studies wey Makanjuola do on Yoruba traditional healers wey specialise for mental disorder, wey dem conduct for University of Ife for the 1980s.
Asínwín and ode orí na the two main groups wey twenty Yoruba traditional healers wey specialise for mental disorders identify. Asínwín dey cover psychotic disorders. Ode orí na condition wey no too severe but get heavy somatic symptoms .
Ode orí make sense to look well, because na well-characterised culture-bound disorder and clinical study dey on am. Dem assess thirty patients wey Yoruba traditional healers diagnose with ode orí: their main complaints na crawling sensation for head and body, noise for ears, palpitation and different other somatic complaints; anxiety and depressive symptoms show well-well for all the thirty patients; and the most common DSM-III diagnoses wey psychiatric assessment give dem na depressive and anxiety disorders .
Dat finding make sense pass as e first show. The healers dey identify real and consistent clinical population, wey match substantially with anxiety and depression as biomedicine define dem, using category wey build around somatic presentation instead of the mood. The category no be say dem misunderstand depression; na differently indexed description of population wey overlap, wey dem organize around the symptoms wey the patients really complain about. Orí na head, and 04-cosmology treat the concept properly; the somatic-cranial framing no be by mistake.
Wèrè na the normal Yoruba word for madness for general talk, and dem dey use am broadly and pejoratively. Sub-categorisation wey dey reported for literature include wèrè amúturínwá, wèrè ìran and wèrè àfisé, wey dem separate mostly by the cause wey dem attribute to am instead of how e present.
The sub-categorisation na aetiological. Na dis structural point Makanjuola study establish: the further division of mental disorders by dis healers na mostly on aetiological basis instead of symptomatic one . The most important causal factors wey the healers identify na action of enemies with big emphasis on the use of supernatural powers; self-induced disorders, wey cannabis abuse be the example dem mention pass; ṣọ̀pọ̀nná, smallpox; and hereditary factors, with the healers account of how hereditary transmission dey happen differ well-well from wetin modern medicine talk .
Two things for dat list deserve comment. The healers independently identify cannabis as major cause of psychosis, wey be causal claim wey modern psychiatry largely accept now and wey dem reach through observation. And dem identify heredity as factor, wey also correct, even though dem give mechanism wey no correct. Dis na useful concrete example of wetin the tradition epistemic record look like when person look am close: correct observation, mistaken mechanism, and no be complete validation or complete dismissal wey popular framings dey offer.
The elements dey consistent across accounts. Herbal preparations, some wey get genuine sedative activity. Staying for the healer compound, many times for months, with the patient family present or nearby. Work, especially farm work, as part of the treatment regime. Ritual treatment wey focus on the attributed cause. And physical restraint.
The strengths na real and psychiatry recognise dem. Dem no dey remove the patient from social world. Dem dey carry family join the treatment instead of to exclude dem. The explanatory framework wey dem give patient and family na the one dem already hold, wey dey reduce the alienation wey complete foreign account of the illness dey cause. Cost and proximity dey make the care easy to reach. Na precisely dis features Lambo build on.
The restraint na the problem, and no be historical matter. Human Rights Watch visit 28 facilities for Nigeria between 2018 and 2019, including state hospitals, rehabilitation centres, traditional healing centres and Christian and Islamic faith-based facilities. For 27 out of the 28, staff chain or shackle adults and children . The youngest pikin wey dem chain na ten years; the oldest person na 86 years and e also get visual disability . Among the specific cases wey dem document na one woman for her thirties wey dem chain to car engine for inside shed, together with two men, for traditional healer house for Abẹ́òkúta .
Make we note say this kind abuse no be only traditional healer dey do am. Dem find am for state hospital and inside church and mosque too. As the thing spread like that, e matter for how dem take describe the problem: to chain people wey get mental illness for Nigeria no be Yoruba traditional practice wey modern facility no dey do, na general feature of system wey almost no get capacity, where to tie person down come replace treatment for every sector. This one na explanation, no be excuse.
Thomas Adeoye Lambo (29 March 1923 to 13 March 2004) dem born am for Abẹ́òkúta, e go Baptist Boys' High School for there, collect im medical degree for University of Birmingham, and specialise for psychiatry for Institute of Psychiatry, King's College London, for 1952 . E return come Nigeria for 1954 as the first indigenous Nigerian psychiatrist and take charge of the neuropsychiatric hospital wey dem just build for Aro, Abẹ́òkúta .
The problem wey e face. New hospital, catchment area wey cover plenty people, and bed no dey enough at all. The normal thing wey dem for do na to put people for waiting list. Wetin e do instead na to rethink where treatment suppose happen.
The system. From 1954, and as e come formalise am for 1956, Lambo arrange with the villages wey dey around Aro, especially Aro and Ope-Oluwa, to make psychiatric patients stay for ordinary village households . Dem post nurses make dem dey provide twenty-four hour cover. Normally, one or two family members dey follow each patient and live with dem throughout the time . Patients dey go the hospital for daytime for treatment and return go the village for night, so the arrangement work like combination of day hospital and foster home . Lambo still ask for cooperation from farmers wey dey near the hospital make dem take patients do work as labourers while dem dey receive treatment . Between 200 and 300 patients get place to stay across four villages around Aro, and dem come from wide geographical area, on top one model wey Lambo link to the Belgian precedent for Gheel .
Traditional healers join body do am, dem no be competitors. Lambo bring traditional healers enter the arrangement make dem work as practitioners alongside the psychiatric staff . Na this feature make Aro dey historically unique: e no be modern service wey just manage traditional practice for corner, na service wey join am deliberately, because e reason say the healers already get the community confidence, dem already dey work in a residential family-centred way, and dem already get the explanatory framework wey patients understand.
Wetin Lambo talk about why e work. E believe say patients wey stay for village adapt to their situation quick quick pass those wey enter hospital, because of contact with environment wey dey settled, tolerant, and healthy . The mechanism wey e propose na social instead of pharmacological, and na the same mechanism community psychiatry for other places later adopt.
The research programme. The Aro team, as dem work with Cornell University, carry out the first community psychiatric epidemiology for Africa. The result na Alexander H. Leighton, T. Adeoye Lambo, Charles C. Hughes and colleagues, Psychiatric Disorder Among the Yoruba: A Report from the Cornell-Aro Mental Health Research Project in the Western Region, Nigeria (Cornell University Press, 1963) . Im importance dey for methodology just as e dey for substance: e prove say person fit study psychiatric disorder for West African rural population with epidemiology, for time wey the view wey dey ground from colonial era talk say Africans no dey suffer the disorders of civilisation.
Im work after Aro. Lambo be Vice-Chancellor of the University of Ibadan from 1967 to 1971, and then Deputy Director-General of the World Health Organization from 1971 to 1988 . That last position na the channel wey make the Aro experience reach global health policy, and na big part of why dem dey cite the model internationally.
Wetin Aro be and wetin e no be. E be genuine and early example of community psychiatry and of deliberate integration with traditional practice, and e run on a big scale. But based on the evidence wey this compiler find, controlled comparative outcome data from that period no dey to support am. The claim say patients do better pass as dem for do if na inpatient dem be na Lambo clinical judgement and the reputation of the system, no be trial result. The influence of the model get proper record; im comparative efficacy for the 1950s and 1960s no be wetin dem measure by the standards wey dem go demand today. Confidence on the historical facts: high. On comparative outcomes in the period: contested.
Wetin the Aro period lack, today get am. The COSIMPO trial na the strongest evidence anywhere on whether collaboration between traditional and faith healers and conventional providers dey improve outcomes for psychosis, and na Oye Gureje lead am from Ibadan .
Design. Cluster-randomised trial for Kumasi, Ghana and Ibadan, Nigeria. Clusters, wey each of dem na primary care clinic with neighbouring traditional and faith healer facilities, dem randomise dem 1:1 stratified by size and country to manualised collaborative shared care intervention wey trained healers and primary health care workers deliver, or to enhanced care as usual. Eligible participants na adults wey dem newly admit to healer facilities wey get active psychotic symptoms wey score 60 or pass on top the Positive and Negative Syndrome Scale. Primary outcome na change for PANSS at six months, wey dem assess masked .
Result. Between September 2016 and May 2017, dem divide 51 cluster by random, 26 for intervention and 25 for control, with 307 patient wey join, 166 for intervention and 141 for control; 190, or 62 percent, na men. Baseline mean PANSS score na 107.3 for intervention and 108.9 for control. 286 patient, wey be 93 percent, complete six-month follow-up. Mean total PANSS for six months na 53.4 inside the intervention group compared to 67.6 inside the control group, with adjusted mean difference of -15.01 (95% CI -21.17 to -8.84, p = 0.0001) .
Bad practice-dem. The trial measure chain-tying and oda practice wey follow am directly. Dem reduce from 94 out of 166 patient, 57 percent, for baseline to 13 out of 152, 9 percent, for six months inside the intervention group, and from 59 out of 141, 42 percent, to 13 out of 134, 10 percent, inside the control group, without any big difference between the groups .
Dat last thing wey dem find need make person look am well, because e go against wetin the intervention self claim. Tying person with chain drop well-well for both group, and the intervention no reduce am pass as normal enhanced care do. Wetin reduce tying, from wetin dem see, na the fact say trial self dey ground: the engagement, attention, and medicine wey reach hand wey make tying no too need again. The real effect wey the intervention show dey on symptom-dem, no be on chaining.
Cost and harm-dem. Dem see bigger drop for total health service and time cost inside the intervention group for six months, even though total money wey dem spend overall high pass, na 627 US dollars per patient compared to 526 for the control group. Five intervention patient get small extrapyramidal side effect .
Conclusion. The people wey write the paper conclude say collaborative shared care wey traditional and faith healer-dem do together with conventional health worker-dem for people wey get psychosis work well, e save money, and e give hope say dem fit expand better care go meet people wey need help for area wey no get plenty resource .
Dis na big, well-conducted, masked, randomised trial wey get fourteen-point PANSS advantage and 93 percent follow-up, wey dem publish inside The Lancet. Na the single strongest evidence for dis whole section, and wetin e dey look na directly the question of whether tradition and modern medicine fit work together instead of whether any of dem fit work alone. The answer wey e give na yes, on symptom-dem, with cost, and e no solve the chaining problem by imself.
Nigeria official mental health capacity small well-well compared to the population, and na traditional and faith healer-dem dey see majority of people wey get psychosis . So the realistic option-dem wey dey na either collaboration or nothing, and trial evidence don show now say collaboration dey work on the outcome wey matter pass to patient-dem.
The matter of tying person na different thing and e need im own answer. E no show different result because of the collaborative intervention, e dey happen for government facility just as e dey happen for traditional place-dem, and HRW document-dem show say e still spread well-well . To treat am as regulation and enforcement problem instead of cultural problem na wetin the evidence support.
How divination functions as a diagnostic instrument and what kind of reasoning it supports, and Hallen and Sodipo's finding that Yoruba herbalists distinguish knowledge from belief by a criterion stricter than the English one.
What the Yoruba word for medicine covers, how physical and spiritual causation work together inside one diagnostic act rather than in separate compartments, and why calling this system "traditional" as opposed to "scientific" describes it wrongly.
What is actually being researched now, how Nigeria regulates traditional medicine and where the regulation stops, who owns knowledge that becomes a drug, and the contamination data that make the contemporary trade a public health problem in its own right.
The orisa of smallpox and of the earth's diseases, the naming taboo, the priesthood's control of epidemic, and the 1907 British colonial ban on the cult which is one of the most consequential state interventions in Yoruba religion.
Who actually practises Yoruba medicine, how the specialisms divide, how a practitioner is trained and how long it takes, and how expertise is checked among practitioners themselves rather than by any outside body.
The scale of the documented Yoruba pharmacopoeia, how plants are classified and named, the tonal wordplay that makes a plant's name a mnemonic for its use, and a worked table of named plants against what pharmacological research has and has not established.
