 the wall in an attempt to make the
       nitroglycerin explode.

        allow sufficient “slack”
                     Restraints

    and chest and take full breaths
   The officer must accompany the patient in the

Neurotransmitters
  and Behavior
      Neurotransmitters: Norepi

   Mania and delusions with overstimulation
   Depression with low levels
    Neurotransmitters: Dopamine

   CNS locations: cerebral cortex,
    hypothalamus and limbic system

   Controls sleep, sensory perception, mood
    control

        Suppress hallucinations and delusions
        Side effects: hypotension, dystonic reactions
         Drug Therapies: Lithium

   Metallic compound

A 24 year-old female was seen for manic-
type symptoms. She had irritability, rapid
speech and distracted conversation. These
symptoms had progressed over a 1-week
period.

She had no history of mental illness or drug
intoxication.

and she was diagnosed with thyrotoxicosis.

bipolar disorder was experiencing
significant withdrawal and depression.
