Summary

• Before a diagnosis the psychiatrist must make a thorough evaluation including a physical/medical exam, a mental status exam, appropriate labs, and a full history.

• History includes changes in thinking, behavior, movement, mood, etc. as seen by the family.

Medications

• In general it may take up to 6 months for medications to show consistent effects.

• The newest medication is:– Paliperidone (Invega)

• Atypical antipsychotics: – Abilify, Geodon, Clozapine, Risperidone,

Seroquel, Zyprexa. – [Remember: a giraffe can really see a zebra]

• These medications may have such intolerable side effects that the patient will stop the drugs.

• More commonly seen in treatment with typical antipsychotics– Chlorpromazine Thioridazine– Levomepromazine Fluphenazine– Haloperidol Trifluoperazine

Treatments

• Psychotherapy - an adjunct to meds and is very useful to keep the patient on the meds.

• Group therapy

• Family therapy

• Community support groups

• Early detection and treatment has the best results/response to treatment.

• Per patients, once you have schizophrenia you have it for life. The best you can hope for is control.

Communication Technique

• Confrontation = Presenting the patient with a different reality of the situation.

Ex:

Patient: My best friend never calls. She hates me.

Nurse: I was in the room yesterday when she called.

Communication Technique

• Doubt =Expressing or voicing doubt when a patient relates a situation.

Ex:
