The mysterious illness of dyce sombre

The alleged "madness" of the Anglo-Indian prince known as Dyce Sombre (1808-1851) has been attributed to anti-Asian prejudice, biased observations, and insensitivity to ethno-cultural variations in behavior. However, whereas all these factors may have contributed to misdiagnosis and mistreatment, there is compelling evidence pointing to an "organic" explanation for Dyce Sombre's aberrant behavior. We posit that the interaction of drug toxicity and possible central nervous system infection were primarily responsible for Dyce Sombre's clinical symptoms. The case provides an important lesson for modern-day psychiatrists confronting patients from other cultures who may also have underlying neuropsychiatric disorders.
