What claudius can teach us
Although Claudius’ symptoms cannot be diagnosed with certainty, the information and perspective available today offer insight into his likely psychiatric problems. His case reminds us that:
- Patients often have multiple diagnoses. Bipolar disorder is strongly associated with substance abuse disorder—particularly alcoholism.
- Lead-containing alcoholic beverages are still a public health concern. Morgan et al13 tested 115 samples of moonshine from nine southeastern, south central, and north central U.S. states. One-third of samples contained lead >300 μg/dL. The authors estimated that excessive consumption of 25% of the samples could lead to blood lead levels consistent with lead poisoning (≥25 μg/dL).
