Cultural epidemiology of neurasthenia spectrum disorders in four general hospital outpatient clinics of urban Pune, India.

Disorders emphasizing symptoms of fatigue and/or weakness, collectively termed Neurasthenia Spectrum Disorders (NSDs), typically emphasize a biological basis in the West and social origins in East Asia.

Prevalence of clinically significant functional fatigue or weakness in specialty outpatient clinics of Pune, India.

Disorders of fatigue are important in clinical practice but inadequately studied in developing countries. Questions about their consistency and variation across cultures also require attention. The standard professional diagnostic formulations of these disorders, namely, chronic fatigue syndrome and neurasthenia, are not used widely in India, perhaps due to lack of research and poor appreciation of their clinical significance.
