Abstract:
Depressive states may at times be particularly tricky to ascertain or confirm during a time-limited consultation. For example, a patient may present with what has been termed as smiling depression. We present the case of a female patient with bipolar II disorder whose difficult-to-ascertain depression could be confirmed by her automatic wristwatch, which regularly stopped when she was hypokinetic as a result of her depression.
