How would you know. . .

No doubt you run into a lot of odd people and people doing odd things in the course of your work. But how would one know if a person you encounter is just a bit odd or really mentally ill? In this case, I mean “mentally ill” to refer to individuals who are out of touch with reality and who may need help to keep themselves or others safe.

There are no sure ways to know. Sometimes, it can take mental health personnel weeks to figure it out. And it can be hard to tell if someone is psychotic or on drugs or both. But there are some things that should make you suspicious:

  • The individual is talking to himself—at least it looks to you like he is talking to himself. He is probably responding to voices he hears but you don’t
  • He seems unduly frightened—of you, of anything around him. You don’t see anything really scary but he seems terrified
  • What he says makes no sense. The words might be mixed up and put into sentences that don’t appear to have any meaning
  • When you ask a question, you get either no answer or an answer that has nothing to do with what you asked
  • He thinks people are out to get him—but it doesn’t seem likely given the specifics. Maybe it is the Martians or the KGB—maybe it is the neighbors all trying to break in repeatedly when you see no evidence of that
  • Clothing doesn’t match the weather. It is July and he is wearing a winter coat and mitts—or it is February and he is wearing a light coat but seems immune to the cold
  • He doesn’t respond—he has a blank expression, a wide-eyed stare. You say things and it’s like he didn’t hear you
  • He uses words in strange ways. They might be normal words but he uses them as if they meant something else—or he has made up words altogether.
  • He thinks he has special powers. He can jump off the bridge but won’t get hurt, he can wave his hand and strangers will come to his rescue
  • He thinks thing have special meanings—the fact that you parked on the left side of the street means that you are a spy; the fact that there is a hydrant means that a tidal wave is coming to drown us all
  • He assumes odd postures—stands or sits in strange ways—and stays that way for long periods
  • He repeats the same word or phrase over and over, or makes the same gesture over and over or paces or walks in circles over and over, for no apparent reason

There are other symptoms of mental illness as well but these are the ones that you are most like to come across in your work.


OK—but if you do decide someone is likely mentally ill, then what? What are you supposed to do?

  • Assess risk as you would in any other situation
  • Keep your distance-but don’t hide if you can avoid it. They are less likely to react if they can see you than if you sneak up on them (but of course safety comes first..)
  • Listen
  • Don’t argue with things that don’t make any sense to you. Be sympathetic. It must be very scary to think there are people out to get you. You can say that. “Gee, it must be very scary for you…” We all say things that don’t make sense at times and none of us like to have it pointed out!
  • If a person is hearing voices, remember that you are essentially butting into a private conversation when you address the person. Be courteous and remember that there’s a lot going in their head right now.
  • Remember that a show of force may well make things worse not better, especially if they are scared already. You never know what this person’s past experience has been with “uniforms,” or what they might mean to him in his current frame of mind.
  • Take your time
  • Smile. It’s amazing how much that can defuse a situation—unless it looks like you are laughing at them
  • Keep communication short and simple. If their speech is confused, you can be sure their thoughts are confused. It is going to be hard for them to understand and follow your directions. Make one request at a time.
  • Slow and steady. Unless they are clearly out of control or getting violent, just keep steady—don’t raise your voice, repeat things, offer simple choices, reassure
  • But no matter how confused they are, they are likely aware you are there and may be aware of what you saying. Don’t talk as if they are not there.
  • Try not to look threatening. Again, it makes them more scared and thus more likely to risk some kind of violence.
  • Take the least action possible. If a person simply appears mentally ill but is not doing anything to harm himself or anyone else, no action may be the best action
  • Try to locate a contact—case worker, a family member, a friend
  • Don’t lie—if you are taking them to hospital or jail or wherever, you might as well be upfront about it because they will know soon enough! And since statistics indicate that many of our callers are repeat callers, there’s no point making things worse for the next time
  • It is ok to back off. Closing in may put you at risk of harm and without an “escape” route, you may feel compelled to take action that harms the subject.
  • Good questions to ask to find out if the person has a psychiatric illness without saying that point blank:

“Do you have a problem with your nerves?”
“You look upset—what is bothering you?”
“Is there someone I can call to help? Do you have a worker or a doctor?”
“Are you taking any medication?”
“I can’t hear the person you are talking to. What they are saying?”
“You seem very frightened.

But above all, respect, a calm demeanor and patience combined with a healthy regard for safety issues is the key.
