Schizophrenia Chapter 16
______ is used to screen for symptoms of movement disorders. The client is observed in several positions, and the severity of symptoms is rated from 0 to 4.
Abnormal Involuntary Movement Scale (AIMS)
The assessment of affect requires sensitivity to differences in _______, _______, and _______ ; these vary across cultures.
eye contact, body language, and acceptable emotional expression
Negative symptoms/signs include:
flat affect, lack of volition, and social withdrawal or discomfort.
Immediate course
two typical patterns 1. the client experiences psychosis and never fully recovers 2. client experiences psychosis and recovers completely
The theory regarding serotonin suggests that serotonin ______ and ______. Some believe that excess serotonin itself contributes to the development of schizophrenia.
modulates and helps to control excess dopamine.
The research consistently shows decreased brain ______ in the frontal and temporal areas of persons with schizophrenia.
volume and abnormal brain function
Nonneurologic side effects include:
weight gain, sedation, photosensitivity, and anticholinergic symptoms such as dry mouth, blurred vision, constipation, urinary retention, and orthostatic hypotension.
Neuroleptic malignant syndrome (NMS) is a serious and frequently fatal condition seen in those being treated with antipsychotic medications. It is characterized by signs and symptoms:
muscle rigidity, high fever, increased muscle enzymes (particularly creatine phosphokinase), and leukocytosis (increased leukocytes).
In schizophrenia higher relapse rates are associated with:
non-adherence to medication persistent substance use caregiver criticism negative attitude toward treatment
The primary medical treatment for schizophrenia is ______.
psychopharmacology
Tx
psychotic and mood symptom 1st gen- dopamine antagonists: + signs 2nd gen dep and sero antagonist: = and - signs LAIS: 6 shots available 2-4 weeks
schizophrenia causes distorted and bizarre:
thoughts, perceptions, emotions, movements, and behavior.
Clozapine (Clozaril)
atypical antipsychotic acts on both positive and negative signs
replaces usually occurs with in
1 year
The symptoms of schizophrenia are divided into two major categories:
1. Positive or hard symptoms/signs. 2. Negative or soft symptoms/signs.
The peak incidence of schizophrenia onset is ___ to ___ years of age for men and ___ to ___ years of age for women.
15 to 25; 25 to 35
______ medications play a crucial role in the course of the disease and individual outcomes.
Antipsychotic
______ medications, also known as neuroleptics, are prescribed primarily for their efficacy in decreasing psychotic symptoms. They do not cure schizophrenia; rather, they are used to manage the symptoms of the disease.
Antipsychotic
African Americans, white Americans, and Hispanic Americans appear to require comparable therapeutic doses of antipsychotic medications. ______ clients, however, need lower doses of drugs such as haloperidol (Haldol) to obtain the same effects; therefore, they would be likely to experience more severe side effects if given the traditional or usual doses.

DSM-5 DIAGNOSTIC CRITERIA: Schizophrenia. Continuous signs of the disturbance persist for at least 6 months. This period must include at least 1 month of symptoms (or less if successfully treated) that meet Criterion A (i.e., active-phase symptoms) and may include periods of prodromal or residual symptoms. During these prodromal or residual periods, the signs of the disturbance may be manifested by only negative symptoms or by two or more symptoms listed in Criterion A present in an attenuated form (e.g., odd beliefs, unusual perceptual experiences).
DSM-5
DSM-5 DIAGNOSTIC CRITERIA: Schizophrenia. Two (or more) of the following, each present for a significant portion of time during a 1 month period (or less if successfully treated). At least one of these must be (1), (2), or (3): 1. Delusions. 2. Hallucinations. 3. Disorganized speech (e.g., frequent derailment or incoherence). 4. Grossly disorgranized or catatonic behavior. 5. Negative symptoms (i.e., diminished emotional or avolition).
DSM-5 criteria
______ reactions to antipsychotic medications appear early in the course of treatment and are characterized by spasms in discrete muscle groups such as the neck muscles (torticollis) or eye muscles (oculogyric crisis). These spasms also may be accompanied by protrusion of the tongue, dysphagia, and laryngeal and pharyngeal spasms that can compromise the client's airway, causing a medical emergency.
Dystonic
______ also may be a factor in the way a person responds to psychotropic medications. This difference in response is probably the result of the person's genetic makeup. Some people metabolize certain drugs more slowly, so the drug level in the bloodstream is higher than desired.
Ethnicity
Related Disorders
Schizophreniform disorder( acute psychosis >6 months) Catatonia( chartizerized by marked psychomotor disturbance Delusional disorder (believes the delusion is real) Brief psychotic disorder( psychotic symptoms 1 day to 1 month) Shared psychotic disorder ( two people share similar delusions) Schizotypical personality disorder( odd, eccentric behaviors )
______, a late-appearing side effect of antipsychotic medications, is characterized by abnormal, involuntary movements such as lip smacking, tongue protrusion, chewing, blinking, grimacing, and choreiform movements of the limbs and feet.
Tardive dyskinesia
Seizures may be associated with high doses of the medication. Treatment is:
a lowered dosage or a different antipsychotic medication.
Pseudoparkinsonism, or neuroleptic-induced parkinsonism, signs and symptoms includes:
a shuffling gait, mask-like facies, muscle stiffness (continuous) or cogwheeling rigidity (ratchet-like movements of joints), drooling, and akinesia (slowness and difficulty initiating movement). These symptoms usually appear in the first few days after starting or increasing the dosage of an antipsychotic medication.
Schizophrenia usually is diagnosed in late ______ or early ______. Rarely does it manifest in ______.

Many clients with schizophrenia have difficulty ______ and ______. This is primarily due to persistent negative symptoms, impaired cognition, or treatment-refractory positive symptoms.
