Frontal lobe dementias often make some of our most memorable patients. The reason is that your frontal lobe is your social filter, if you will. Some of you will remember Phineas Gage's story from over 100 years ago. If not, look it up. Imagine for a moment if you just spouted out all the thoughts that come into your head every day, out loud, the moment you had them. Now imagine if you didn't have the filter that comes before those thoughts arise. You know, the filters that say "Hey, that's racist/sexist. You shouldn't think like that." (My filter screams "Get out of my head!" at random intervals). Minus those filters, imagine the conversation stoppers you could drop with almost every line that came out of your mouth.
Patient: "I need to ask you something."
Nurse: "What's that?"
Patient (sticking out tongue): "If I stick my tongue out like this, do you think you could back that ass up on it?"
