Summary
Screening questionnaires effectively detect neurological disorders in developing nations. This systematic review validates their use for early detection and implementing crucial prevention strategies.
Area of Science:
- Neurology
- Public Health
- Epidemiology
Background:
- Neurological disorders are a major global cause of disability and death.
- Their prevalence and impact are significant in developing countries.
- Screening questionnaires are vital tools for identifying these conditions.
Purpose of the Study:
- To systematically review the validity of screening questionnaires for neurological disorders in developing countries.
- To assess the diagnostic accuracy of available tools.
- To inform public health strategies for neurological disorder management.
Main Methods:
- Systematic literature search of PubMed/MEDLINE, Scopus, Science-Direct, and PASCAL databases.
- Inclusion of studies conducted in developing countries, assessing risk of bias with QUADAS-2.
- Reporting of summary measures including sensitivity and specificity.
Main Results:
- 49 articles were selected from 835 records.
- Epilepsy, stroke, and neuropathies were most frequently detected.
- Two key questionnaires, WHO Protocol and Ten Questions, showed high sensitivity (84-100% and 56-100%).
Conclusions:
- Screening questionnaires are validated instruments for detecting neurological disorders in developing countries.
- Effective disease detection facilitates epidemiological data collection.
- Implementation of prevention strategies can reduce the global burden of neurological disorders.
