Normal pressure hydrocephalus presents with the classic triad of "wet, wobbly, and wacky":

  • Wet - urinary incontinence
  • Wobbly - gait apraxia
  • Wacky - cognitive dysfunction (memory issues)

FA2020 p522

According to the BrosWorld deck, they tend to try to hide the classic triad in longer stems (such as this one), even though they give the triad outright in the first sentence.

Pick disease is the old name for frontotemporal dementia and early changes are more likely to be personality change or aphasia. Alzheimers is a slow progression of memory loss and not typically associated with urinary incontinence. Parkinson would typically present with symptoms like tremor, rigidity, or shuffling gait. A cerebral neoplasm can cause a variety of neurologic symptoms but is more likely to present with symptoms like headaches and focal neurologic deficits.
