DSM-V Flashcards
DSM-V Criteria for Schizophrenia
A = ≥2 of the following, present for a significant portion of time during a 1 mo period (less if successfully treated). At least one of these must be (1), (2), or (3)
- Delusions
- Hallucinations
- Disorganized speech (e.g. frequent derailment or incoherence)
- Grossly disorganized or catatonic behaviour
- Negative symptoms
(i. e. diminished emotional expression or avolition)
B = ↓ level of function: for a significant portion of time since onset.
- One or more major areas affected (e.g. work, interpersonal relations, self-care) is markedly decreased
- If childhood/adolescent onset, failure to achieve expected level
C = at least 6 mo of continuous signs of the disturbance. Must include at least 1 mo of symptoms that meet Criterion A (i.e. active-phase symptoms) and may include periods of prodromal or residual symptoms
(the disturbance may manifest by only negative symptoms or by two or more Criterion A symptoms present in an attenuated form - e.g. odd beliefs, unusual perceptual experiences)
D = Exclude schizoaffective disorder and depressive or bipolar disorder with psychotic features
E = Exclude other causes: GMC, substances (e.g. drug of abuse, medication)
F = If history of autism spectrum disorder or communication disorder of childhood onset, the additional diagnosis of schizophrenia is made only if prominent delusions or hallucinations are also present for at least 1 mo
DSM-V Schizoaffective disorder
A – An uninterrupted period of illness where there is concurrent psychosis (criterion A of schizophrenia) and major mood episode.
B - delusions or hallucinations for ≥ 2 weeks in the absence of a major mood episode during the lifetime duration of the illness
C - major mood episode symptoms are present for the majority of the total duration of the active and residual periods of the illness
D - the disturbance is not attributable to the effects of a substance or another medical condition
note: difference between schizophrenia and schizoaffective disorder is that schizoaffective disorder has a prominent MOOD component (manic or depressed) as apposed to schizophrenia where mode symptoms may present but they are NOT prominent
DSM-V criteria Brief Psychotic Episode
A psychotic illness that meets criteria A + D + E of schizophrenia BUT with a very short duration of symptoms (1day - <1m total) with eventual resolution to full pre-morbid functioning. If the symptoms extend past 1 month, it become schizophreniform disorder.
Managed with secure environment, antipsychotics and anxiolytics. This condition is self-limiting and has a good prognosis. Most return to normal pre-morbid functioning within a month.
DSM-V for Schizophreniform disorder
A psychotic illness that meets criteria A + D + E of schizophrenia BUT with a shorter duration of symptoms (1 -6m total). If the symptoms extend past 6 months, it become schizophrenia.
Full rapid resolution of symptoms is associated with better prognosis. Can develop into schizophrenia.
DSM-V for a Delusional disorder
A = The presence of one (or more) delusions with a duration of 1 mo or longer
B = Criterion A for schizophrenia has never been met
Note: hallucinations, if present, are not prominent and are related to the delusional theme
C = Apart from the impact of the delusion(s) or its ramifications, functioning is not markedly impaired, and behaviour is not obviously bizarre or odd
D = If manic or major depressive episodes have occurred, these have been brief relative to the duration of the delusional periods
E = The disturbance is not attributable to the physiological effects of a substance, another medical condition or mental disorder
DSMV Depressive episode
A = ≥ 5 of the following have been present during the same 2 week period and represent a change from previous functioning: (one must be low mood or anhedonia)
a. Depressed Mood most of the day, nearly every day as indicated by either subjective report (empty, sad, hopeless) or observation
b. Markedly diminished Interest or pleasure in all, or almost all activities most of the day, nearly every day
c. Significant weight loss / gain (e.g., ≥ 5% of body weight in a month) or decrease or increase in Appetite nearly every day
d. Insomnia or hypersomnia nearly every day (Sleep)
e. Psychomotor agitation or retardation nearly every day
f. Fatigue or loss of Energy nearly every day
g. Feelings of worthlessness or excessive or inappropriate Guilt nearly every day
h. Diminished ability to think or Concentrate or indecisiveness nearly every day
i. Recurrent thoughts of death (suicidal ideations +/- plan or suicide attempt)

C = Episode is not attributable to physiological effects of a substance or to another medical condition
“MSIG E CAPS”
DSMV Manic Episode
For Bipolar, one must meet the following criteria of a manic episode (at least 1 episode in lifetime)
A = A distinct period of abnormally and persistently elevated, expansive or irritable mood and abnormally and persistently increased activity or energy, lasting at least 1 week + present most of the day, nearly every day
B = During the period of mood disturbance and ↑ energy or activity, ≥3 of the following are present to a significant degree and represent a noticeable change from usual behaviour
a. Inflated self-esteem (Grandiosity)
b. Decreased need for sleep
c. More talkative than usual or pressure to keep
talking
d. Flight of ideas or subjective experience that thoughts are racing
e. Distractibility
f. Increase in goal directed Activity or psychomotor agitation
g. Excessive involvement in Activities that have a high potential for Painful consequences
C = The mood disturbance is sufficiently severe to cause marked impairment for social or occupational functioning or to necessitate hospitalisation to prevent harm to self or others, or there are psychotic features
D = The episode is not attributable to physiological effects of a substance or to another medical condition
DSM-V Hypomanic episode
▪ Same as above but not severe enough to cause marked impairment for social or occupational functioning
▪ It is associated with an unequivocal change in functioning that is uncharacteristic of individual when not symptomatic
▪ Disturbance in mood and the change in functioning are observable by others
Bipolar subtype 1
▪ 1 or more manic or mixed episodes have occurred
▪ Commonly accompanied by at least 1 MDE (but not needed for diagnosis)
▪ If the patient needs hospitalisation or has psychotic symptoms it’s BPAD I
▪ Disorder may become apparent after a patient is given a course of antidepressant
monotherapy for their depressive symptoms.
Bipolar subtype 2
▪ 1 or more hypomanic episodes (4 or more weeks) AND 1 or more major depressive episodes
▪ BPAD II is often under diagnosed + under reported as the MDEs are long and there is poor recognition of hypomanic episodes
Cyclothymia
▪ Alternating between hypomanic and mild/moderate depressive symptoms for at least 2 years (never without symptoms for more than 2 months)
▪ These people have never reached criteria for an MDE, manic or hypomanic eps.
▪ Patients are higher functioning but the symptoms still cause distress or impairment
in important areas of functioning.
▪ Management is the same as BPAD I = mood stabiliser +/- psychotherapy, avoid
antidepressant monotherapy, address substance use.
Dysthymia
▪ Long standing depressed mood but does not fulfil criteria for recurrent depressive disorder. They feel tired + depressed and everything is an effort
DSM V Adjustment Disorder - Criteria, Clinical Presentation and Management Plan

MANAGEMENT PLAN/APPROACH–>Aim = manage distress and prevent PTSD
Psychological First Aid
▪ Ensuring person’s safety + support (provide medical care if needed)
▪ Acknowledge the stress reaction
▪ Provide information about event + resolution
▪ Offer practical assistance
▪ Assess suicide risk, risk to others + dependants
▪ One off debriefing is NOT recommended as they can increase symptoms and
are not effective in treating ASD or preventing PTSD.
Psychology Inputs
▪ Psychoeducation to understand ASD and encourage use of inherent strengths, support networks and positive judgement.
▪ Understanding of adaptive mechanisms and developing coping mechanisms
▪ Cognitive behavioural therapy (good to decrease symptoms and ways to deal with
future events)
▪ Fostering + enhancing the therapeutic alliance
Pharmacotherapy in select situations (Senior Doctor Discretion)
▪ SSRIs for intrusive thoughts or low mood
▪ Benzodiazepines for anxiety + insomnia
▪ Anticonvulsants or Beta blockers may be helpful in some symptom clusters but this is
at the specialist’s discretion

EYE MOVEMENT DESENSITISATION + REPROCESSING (EMDR)
▪ an experimental method of reprocessing memories of distressing events by
recounting them while using a form of dual attention stimulation such as eye
movements, bilateral sound, or bilateral tactile stimulation
▪ Its use is controversial because of limited evidence

TREATMENT
- Similar to panic disorder
- EXCLUDE ORGANIC ILLNESS
= Thyroid ↑, caffeine, stimulants, alcohol withdrawal
= Adjustment disorder with anxious mood
= If older person, think depression ot dementia with anxious mood
- LIFESTYLE = ↓ caffeine = Good sleep hygiene = Avoid alcohol and other drugs (must explore this area as many patients self-medicate)
- PSYCHOTHERAPY (first line!!)
= psychoeducation
= CBT = interoceptive exposure (eliciting panic attack symptoms and learning how to tolerate them with coping strategies)
= Stress management = scheduling, problem focused counselling
= Relaxation techniques - MEDICATIONS (if therapy alone is not enough)
= 1st line – SSRIs / SNRIs (paroxetine, escitalopram, sertraline, duloxetine, venlafaxine)
= 2nd line – buspirone (TID), buproprion (caution stimulating SEs)
= Don’t need high doses usually
= Add Benzodiazepines if needed (short-term, low dose, regular schedule, long half-life, avoid prn usage)
= DO NOT USE BETA-BLOCKERS
NOTE: C-First Symptoms Concentration Fatigue Irritability Restless Sleep Disturbance Tension (muscle)
