Q

prevalence

A

no differences in race, social status, culture or environment

males: earlier onset (18-25): more structural brain abnormalities, more prominent neg symptoms

females: later (23-35): less structural abnormalities, better outcomes, early onset schizophrenia

Q

prognosis

A

outcome diff to predict
uncommon for patients to return to full premorbid functioning

factors associated w/ pos outcomes: early recognition, fem gender, abrupt onset of symptoms w/ obvious precipitating factors, rapid resolution of active phase, absence of structural brain abnormalities, norm neuro functioning, no fam hx of schizo

cognitive impairments: chronic metabolic conditions, substance abuse, stress, freq + intensity, residual symptoms, social deficits

extremely detailed and lengthy discourse about a topic
36
speech alteration interventions
Explain how their behaviors or verbalizations may disturb others Anticipate client’s needs Orient them to reality, call them by name Be concrete in speech avoid abstract phrases, clichés, jokes
37
thinking alterations symptoms
loose associations tangentiality flight of ideas paranoia referential autistic thinking concrete verbigeration
38
perception alterations
depersonalization - lost identity hallucinations - perception w/ no external stimuli (command hallucinations - can be harmful) illusions - misinterpretation of real experience derealization - false perception environment
39
behavior alterations
bizarre behavior stupor stereotyped behaviors automatic obedience waxy flexibility extreme motor agitation negativism aggression, agitation catatonia - posturing, fixed eyes catatonic excitement echopraxia (sim to tics) regressed behavior stereotypy hypervigilance - neg expectation lack of impulse control (agitated behaviors)
40
types of delusions
persecution ideas of reference grandiose erotomaniac - someone in love somatic - beliefs about abnormalities in bodily functions or structures thought insertion - that someone has placed thoughts into one’s mind thought broadcasting - that others can read or hear one’s thoughts delusions of control nihilistic delusion - the belief that one is dead or a calamity is impending paranoia magical thinking
41
delusion interventions
**never argue or agree w/ delusions acknowledge feelings - "must be frightening.." respond to matter-of-fact and calm manner never touch be aware of gestures + non-verbal responses be open, honest, + reliable w/ client neutral stance/introduce neutral topic interject doubt + about delusion if appropriate observe events that trigger delusions distraction from delusion - reality based
42
negative symptoms
diminished emotions avolition - lack of motivation alogia - lack of speech anhedonia asociality - lack of motivation in social
43
positive symptoms
hallucinations delusions
44
types of hallucinations
false sensory perceptions NOT associated w/ real external stimuli + involves 5 senses - auditory, visual, olfactory, gustatory, tactile
45
command hallucinations
**may indicate psychiatric emergency - at risk for violence - must be assessed - can be terrifying to individual - one voice? male or female? if person can give identity - may be greater risk
46
hallucination interventions
ask client what are they seeing, hearing, feeling, smelling - assess command hallucinations - harm self or others? - never react to hallucinations as if they are real - observe for clues that pt is hallucinating - offer own perceptions w/out negating client's experience - focus on reality based diversions - be alert to inc anxiety - avoid touch - try to distract - be empathetic - assess suicide - maintain low level of stimulation - observe behavior freq
47
treatment
team + community approach therapeutic alliance, psychotherapy, group therapy social skills training social services, social support instill hope!! idea to have collaboration between primary provider + psychiatric team

disease education, treatment, SE, prevention symptoms mgmt medication + SE, compliance essential stress mgmt mgmt of medical conditions skills of daily living social skills training (SST) hope instillation
49
teaching strategies
avoid alcohol, drugs reduce stress learn about illness treatment plan
50
antipsychotic meds
alleviate symptoms of schizo but cant cure underlying psychotic processes psychotic symptoms return w/ meds non-adherence effective in - acute exacerbationor schizo, prevent or mitigate relapse
51
conventional (1st gen)/typical antipsychotics
targets pos symptoms *blocks postsynaptic dopamine receptors in basal ganglia, hypothalamus, limbic system, brainstem + medulla *high affinity for cholinergic, alpha 1 adrenergic + histamine receptors
52
atypical (2nd gen) antipsychotics
target positive + negative symptoms fewer motor side effects tx anxiety, depression, + dec suicidal behavior Haloperidol (Haldol) - least sedating chlorpromazine (thorazine) - most sedating fluphenazine (prolixin) min anticholinergic effect - chew sugarless gum, high fiber foods,get up + down slowly risperidone (Risperdal) quetiapine (Seroquel) Olanzapine (Zyprexa) zapine (Zyprexa) clozapine (Clozaril) paliperidone (Invega) ziprasidone (Geodon)
53
extrapyramidal symptoms (EPS)
caused by dopamine blockade 1. acute dystonia 2. pseudo parkinsonism 3. akathisia 4. tardive dyskinesia
54
acute dystonia
Painful muscle spasm of tongue, jaw, face or neck Frightening for pt Onset –within hours or days of starting antipsychotics young males opisthotonos – tetanic spasm in which head and heels are bent backward and body forward Oculogyric crisis – eyes locked upward Torticollis – spasm of the neck in which head is tilted to 1 side with chin pointed to other side tx: Benadryl 25 – 50 mg IM stat - relief in mins
55
pseudo parkisonism
shuffling gait, tremor, drooling, masklike facies, “pill-rolling”, akithesia, muscle rigidity, numbness, tingling sensations Feels slowed down, like a “zombie” Passive range of motion exercise will produce cogwheel rigidity of arms Appears early in drug therapy Cause: too little DA and excess cholinergic activity in basal ganglia –result is tremors Treat with anticholinergic agent like Artane or Cogentin or dopamine agonist or lower dose of antipsychotic
56
tardive dyskinesia
prolonged treatment (Mild, moderate or severe) may be irreversible and disfiguring Involuntary tonic muscular spasms (tongue, mouth, fingers, toes, neck, trunk, pelvis) Early - lip smacking or tongue movements Affects 50% clients using long term antipsychotics AIMS scale for detection of early TD Anticholinergics can worsen s/sx
57
tx of eps
Lowering the dose Prescribing antiparkinsonian drugs: * trihexyphenidyl (Artane) * benztropine mesylate (Cogentin) * diphenhydramine hydrochloride (Benadryl) * amantadine hydrochloride (Symmetrel) *SE early in therapy + can be min
58
clozapine (clozaril)
Used more in treatment resistant cases Not first-line d/t severe adverse reactions: agranulocytosis Severe reduction in WBC -> results IN neutropenia Rare can be fatal S/s : sore throat, fever, malaise, mouth sores Any flu-like sss. should be carefully evaluated
59
SGAs (atypical antipsychotic)
Serotonin -dopamine antagonists (SGA’s) Fewer S/E, better tolerated Lessen negative symptoms Decrease suicidal behavior Improve neurocognitive functioning May cause more weight gain r/t abnormal glucose metabolism Anticholinergic SE Mon weight, BMI, glucose Minimal EPS – exceptions Sexual dysfunction Very expensive
60
metabolic syndrome
SE: Weight gain Type 2 diabetes inc LDL cholesterol triglycerides Dec HDL cholesterol DKA
61
neuroleptic malignant syndrome
*RARE MED EMERGENCY - 10% possible cause - acute reduction in DA s/s: hyperthermia muscle rigidity tremors fluctuating BP’s altered consciousness
62
antipsychotic med edu
dont drive if drowsy dont stop abruptly can cause photosensitivity get routine blood work reports symptoms of sore throat, fever, malaise, unusual bleeding, bruising, n/v, HA, tachy, diff urination, dark urine, excess urine, pale stools, jaundice, skin rash sugarless gum/hard candy good oral care avoid alc/drugs take meds even in feel better orthostatic hypotension precautions
