The impact of leprosy on the mental wellbeing of leprosy-affected persons and their family members - a systematic review

Leprosy has long-term consequences related to impairment and stigma. This includes a major impact on mental health. This study aims to consolidate current evidence regarding the mental health impact of leprosy on affected persons and their family members. In addition, determinants influencing mental health outcomes among leprosy-affected persons and effective interventions are examined. A keyword-based search was conducted in PubMed, Web of Science, Scopus, PsycINFO, Infolep and InfoNTD; additional literature was also considered. Articles presenting primary data involving leprosy-affected persons or their family members experiencing mental conditions were included. Independent extraction of articles was executed using predefined data fields. Articles were sorted according to relevance. In total, 65 studies were included in this systematic review. Multiple psychiatric morbidities have been identified among leprosy-affected persons, including depression, anxiety disorders and suicide (attempts). Additional factors were found that may impact mental health. Moreover, studies found that demographic factors, lifestyle and disease-specific factors and stigma and discrimination impact mental health. Depressive symptoms and low self-esteem were identified among children of leprosy-affected persons. In addition, interventions were identified that could improve the mental wellbeing of leprosy patients. Depressive disorders and anxiety disorders were found to be very common among persons affected by leprosy. Feelings such as fear, shame and low self-esteem are also experienced by those affected, and their children. Further research is necessary to ensure that mental health impact is included when determining the burden of disease for leprosy, and to relieve this burden.

Therapeutic workshops and psychosocial rehabilitation for institutionalised leprosy patients

Leprosy is still a major public health problem and psychosocial rehabilitation services for patients suffering from the disease remain insufficient. This study aimed to assess the impact of therapeutic workshops on quality of life and symptoms of depression among institutionalised leprosy patients. The Beck Depression Inventory (BDI) and generic World Health Organization Quality of Life questionnaire (WHOQOL-BREF) were used before and after the implementation of a series of therapeutic workshops over a period of six months. Sixty-two patients participated in the study. Almost all of the sample were elderly and had a low level of education. There was a significant reduction in the symptoms of depression scores after the intervention (p < 0,001) and a positive impact was shown for the psychological (p = 0,001), physical (p = 0,03) and environment (p < 0,001) domains, but not for the social relationships (p = 0,124) domain. Therapeutic workshops appear to a useful tool for psychosocial rehabilitation work with leprosy patients.

Mental disorders in leprosy: an underdiagnosed and untreated population

OBJECTIVE

To describe the frequency of psychiatric comorbidities in leprosy patients and check if they had been previously diagnosed and were in psychiatric care.

METHOD

The study was conducted with a sample of 120 leprosy patients being treated at two reference hospitals for leprosy in Salvador, Bahia, Brazil. Survey participants were more than 18 years of age, had a confirmed diagnosis of leprosy and was undergoing antimicrobial treatment. Patients were evaluated face-to-face with a socio-demographic questionnaire and the Mini-International Neuropsychiatric Interview (MINI-Plus) in Portuguese. The period of data collection was between October 2009 and June 2012.

RESULTS

The assessment using the MINI-Plus showed that 34 (28.3%) patients did not receive any psychiatric diagnosis and 86 (71.7%) met the criteria for at least one. Of these 86 patients, 25 (20.8%) had one diagnosis, 26 (21.7%) had two diagnoses and the rest, 35 (29.2%), had three or more psychiatric diagnoses. All patients with a moderate or high risk of suicide had one or more psychiatric comorbidities.

CONCLUSION

Leprosy patients have a high prevalence of psychiatric comorbidities. Furthermore, most of them had no previous psychiatric diagnosis and the majority was not undergoing treatment.

Neglected tropical diseases and mental health: a perspective on comorbidity

Mental health conditions will be the largest contributor to the global health burden by 2030. Our review suggests that neglected tropical diseases (NTDs) predispose individuals to poor mental health. Factors predisposing to poor mental health include stigma and discrimination, exclusion from participating fully in society, reduced access to health and social services, lack of educational opportunities, exclusion from income-generation and employment opportunities, and restrictions in exercising civil and political rights. These characteristics are all features of NTDs, but the mental health of these sufferers has been ignored. This review raises an issue of concern and highlights the opportunities for research by psychiatrists and psychologists on NTDs.

The prevalence of dementia and depression in Taiwanese institutionalized leprosy patients, and the effectiveness evaluation of reminiscence therapy--a longitudinal, single-blind, randomized control study

OBJECTIVE

This study investigated the prevalence of depression and dementia in long-term institutionalized older leprosy patients in Taiwan. We then examined the effectiveness of reminiscence group therapy on depressive symptoms and cognitive function in this population.

METHODS

We recruited 129 long-term institutionalized older leprosy patients in Taiwan and used the Geriatric Depression Scale-Short Form (GDS-SF), the mini mental state examination (MMSE), and the Clinical Dementia Rating (CDR) scale for outcome measurement. We then conducted a single-blind, randomized, longitudinal quasi-experimental analysis comparing the pre-test and post-test results of two equivalent groups at a 24-week intervention interval. The intervention in the experimental group was three sessions of reminiscence group therapy per week, whereas that in the control group was weekly individual supportive interviews.

RESULTS

The prevalence of dementia was 45.7-50.4% according to a CDR score ≥ 0.5 and an MMSE score < 25, and the prevalence of depression was 25% based on a GDS-SF score ≥ 7. According to the Wilcoxon signed-rank test, the GDS-SF scores in the experimental group decreased significantly (p = 0.02) after intervention as compared with that in the control group (p = 0.22), whereas the MMSE scores in both groups remained steady.

CONCLUSIONS

The prevalence of dementia and depression in long-term institutionalized older leprosy patients in Taiwan is high. Reminiscence group therapy has been confirmed effective on depression in this population, but its effectiveness on cognitive function requires further verification.
