The easiest way to diagnose a subject in the field is to find out if the subject is on any medications. This can be done by asking the subject or family members what medications the subject is taking. Like any illness, certain disorders are treated with particular medications. Common medications used to treat schizophrenia are Haldol, Resperidol, Clozoril, Prolixin and Chlorpromazine. Prolixin and Haldol can be injected.[PAGEBREAK]
The medications used to treat bipolar illness are Lithium, Tegretol, Klonopin and Depakote.
Personality disorders, as mentioned above, do not respond well to medications. If extreme behaviors are observed and there is no history of psychiatric hospitalization or medication (except for possibly antidepressants) a responsible guess of personality disorder can be made.
Schizophrenic and bipolar subjects behave differently when confronted by the police. Individuals suffering from schizophrenia do not like the feeling of being out of control or having to depend on someone to assist them. However, when approached with a firm, compassionate show of force, these subjects tend to comply with reasonable requests for security and safety. They may say, "Do what you have to do," which translates to "Rescue me; help me to be safe." When more aggressive methods have to be used, such as .12-gauge bean-bag rounds or pepper spray, these subjects submit very rapidly.
In contrast to this, individuals with bipolar illness may enjoy their manic or depressed phase. Their statements will be more like, "Go away, this does not concern you!" or "Just try and stop me!" Their resistance may be both verbal and physical in nature. A large show of force does not intimidate them; it may in fact give them a sense of power or resolve. More aggressive methods, such as use of bean bag rounds, may actually aggravate bipolar subjects to the point of attempting suicide. This may be an attempt to show the police that no one can control them. The use of pepper spray also appears to have little or no subduing effect, and may also aggravate the situation.
