Tardive dyskinesia (TD) is a chronic and often irreversible movement disorder that usually evolves after years of neuroleptic use but can sometimes develop over a much shorter time frame. Paradoxically, a higher dose of the neuroleptic agent that causes TD can often temporarily suppress the movement disorder. This is generally an inadvisable approach, though, as its effectiveness is probably limited to only a matter of weeks and as it will worsen the problem in the long run. We describe a patient with widely metastatic squamous cell carcinoma of the lung who developed severe TD when treated with chlorpromazine for severe hiccups. As his prognosis was only days to weeks, we were able to effectively suppress his TD with haloperidol. Hospice care emphasizes relief of suffering at the end of life, often at the expense of attention to long-range adverse effects, and this approach may be a viable management strategy for patients with TD and very limited prognosis.

Bipolar I disorder and interictal personality syndrome have many overlapping characteristics that are difficult to distinguish. There is scant literature focused on interictal personality syndrome and no case reports to date detailing patients with comorbid bipolar pathology. We describe an individual with a history of bipolar I disorder who developed right temporal lobe epilepsy after several head injuries. He subsequently exhibited symptoms consistent with interictal personality syndrome that were independent of his bipolar symptomatology. Better understanding of these disorders can lead to improved diagnosis and symptom management. The similarities may also point to a partially shared neuropathology.

A previously healthy 68-year-old man rapidly developed a severe melancholic depression following influenza infection. There is an evolving understanding of the complex and possibly bidirectional relationship between depression and inflammation. We review the literature concerning this relationship in the context of viral infection and discuss possible implications for treatment.
