26
What are the common manifestations of social or pragmatic communication disorder?
Deficits in using appropriate communication for context / listener needs. Cannot understand the implied meaning or multiple meanings of words and phrases very well.

What is a provisional tic disorder?
Single or multiple motor tick and/or vocal tics Any tics presenting for <1 year since onset, before age 18
32
What neuroanatomic abnormalities occur in TS?
Basal ganglia dysfunction, with defective cortical input to striatum, and thalamocortical abnormalities. -> small caudate volumes, larger PFC, increased dopamine (D1 for direct pathway = GalphaS) receptor density in striatum in general to make them hypermobile
33
What is the typical progression of tic disorders?
Simple, transient motor tics arise around age 4-6 Rostrocaudal progression of tics Phonic tics appear ages 8-15 (does not happen in all, but if you have a phonic tic you most likely have a motor tic) Tics severity peaks age 10-12 Waxing / waning is normal
34
What is the best psychotherapy for tic disorders?
Habit Reversal Training (HRT) -> Teaches awareness of tic, and "competing response practice" -> channel the urge into a less functionally impairing tic which cannot be seen
35
What are three classes of drugs used in treatment of tic disorders?
1. Alpha-2 receptor agonists - first line (clonidine, guanfacine) 2. D2 receptor antagonists - neuroleptic drugs like haloperidol, risperidone, and pimozide (typical antipsychotics mostly) 3. Botox - for very severe motor / vocal
36
What are the typical etiologies of primary vs secondary enuresis and what does this mean? Which is more common?
Primary - never gained continence -> usually due to maturational delay. Represents 80% of patients. Secondary enuresis - lost continence after at least 1 year of continence -> usually due to a stressor. Less common, starts between 5-8
37
What is the DSM diagnosis of enuresis? What developmental must be met?
Involuntary or intentional voiding into bed or clothes, at least 2x a week for >=3 consecutive months, or presence of distress / impairment Developmental age >= 5 years (better than 90% will have bladder control by this point)
38
What are the pharmacotherapies available for enuresis if there is a major functional impairment? Major risks?
Imipramine - tricyclic with anticholinergic properties, cardiac arrhythmia is a concern DDAVP - desmopressin - reduces urine production, may lead to hyponatremia and seizure due to water intoxication Best treatment: Enuresis alarm
39
What condition must be ruled out before making a diagnosis of encopresis and starting normal treatment?
Psychogenic megacolon pathology: - > children hold feces voluntarily or because of defecation pain - > rectal distention leads to loss of rectal tone / desensitization - > children do not need to defecate -> leads to OVERFLOW encopresis - > need GI to decompact the bowel for treatment
40
What is the DSM criteria for encopresis? What must you specify?
Involuntary or intentional passage of feces at least 1x per month for at least 3 months -> chronological age of at least 4 (vs 5 with enuresis) -> must specify if due to overflow incontinence or not
41
What are the DSM criteria of separation anxiety disorder (SAD)?
Inappropriate, excessive anxiety concerning separation from attachment figures (i.e. Meghan), lasting for 1 month (>4 weeks). Distress from separation, worry about attachment figure, refusal or fear to leave home or be alone, refusal to sleep away from home or without attachment figure. Nightmares w/separation themes common. Starts after a life stress, usually ages 7-9 years.
42
What is the DSM criteria for selective mutism?
For >1 month (not the first month of school), failure to speak in specific social situations despite speaking in others. Interferes with function, not simply due to language / developmental issue -> explains high incidence of social phobia / anxiety later in life
43
Why does encopresis typically arise?
Arises usually as secondary encopresis (>1 yr of continence) with constipation and excessive fluid overflow (overflow incontinence) -> will be small liquid stool. Often precipitated by life events and in reaction to a stressor / anxiety. Can also be primary due to lack of proper toilet training. This is opposite to enuresis which tends to arise as primary, secondary is less common. (It's unlikely that you will have never figured out how to hold your poops).
44

How can an LSD trip be told apart from an acute psychotic episode?
Absence of auditory hallucinations in LSD (visual only)
53
Does a withdrawal syndrome exist for hallucinogens? How do they differ from dissociative drugs?
NO Differ from dissociative drugs because they expand your consciousness Dissociative drugs distort your consciousness and detach you from it Both will act on NMDA receptors
54
What is the mechanism of action of MDMA?
Amphetamine analog -> stimulant properties, but also mild hallucinogenic properties by acting on serotonergic receptors
55

61
What are the criteria for Schizophrenia?
For greater than 1 month (or less if treatment), presence of 2+ ``` Hallucinations Delusions Disorganized speech Disorganized or catatonic behavior Negative Symptoms ``` At least 1 of the 2 has to come from first three (the first three are positive symptoms). Must have a decreased functioning in some aspect of life, and symptoms persist for at least 6 months which are at least prodromal, residual, attenuated, or negative symptoms of Criterion A. That is, even when Criterion A symptoms are treated, you still have not returned to baseline for 6 months.
62
Why is life expectancy decreased in Schizophrenia?
Increase in cardiovascular problems Weight gain and diabetes are common side effects of atypical antipsychotics Substance abuse Insufficient counseling / screening by doctors Suicide / Violence Basically boils down to: The drugs they're taking, what their disorder does to them, and how that becomes the only thing people care about
63
What are the features of "psychotic" behavior?
Delusions Hallucinations Disorganized speech Disorganized and catatonic behavior
64
What are some factors which indicate good prognosis in schizophrenia?
Female (tend to be diagnosed later, also have higher incidence of mood disorder) Later onset Precipitating event or stressor with acute onset Paranoid features Family history of mood disorder, and associated mood change in illness Good interepisode function No gross brain abnormality
65
What is the strongest genetic association with schizophrenia, and what neurological process is this thought to underlie?
Strongly associated with the major histocompatibility complex - > process of errant and excessive synaptic pruning during adolescence and early adulthood may underlie brain volume decrease and prodromal impairments in emotional, cognitive, and motor function - > explains ventriculomegaly with decreased dendritic branching / atrophy of cortex in schizophrenia
66
What are some factors which indicate poor prognosis in schizophrenia?
Physical illness comorbid Substance abuse comorbid Family history of schizophrenia (less related to mood disorders) High emotional conflicts at home (stress = worse outcome) Low treatment compliance Experience side effects w/ antipsychotics
67
By what mechanism are positive and negative symptoms in schizophrenia thought to be controlled
Mesocortical pathway (ventral tegmental area to prefrontal cortex) is thought to lead to cognitive and negative symptoms, and this is due to a decrease in dopamine. Increased dopamine to mesolimbic pathway (VTA to NAcc) leads to positive symptoms
68
What is the unifying NMDA theory of schizophrenia?
Hypofunction of the glutamate NMDA receptor underlies schizophrenia. In the Mesolimbic system, there is an interneuron which is improperly activated when glutamate function is low. As a result, this GABA interneuron cannot inhibit dopamine release to NAcc -> Increased dopamine. In the Mesocortical system, there is no interneuron. We simply cannot stimulate the dopamine releasing neuron to the prefrontal cortex properly because NMDA receptors are not working. Thus, there is decreased dopamine in the prefrontal cortex.
69
How is schizophreniform disorder diagnosed?
Same diagnostic criteria as schizophrenia, although the prodromal, active, and residual phases have gone on less than 6 months at this point. ALSO Decline of function is not required at this point. -> better prognosis = acute delirium features, and more acute onset (less prodromal symptoms)
70
What is Brief Psychotic Disorder?
Same diagnostic criterion A as schizophrenia, MINUS the negative symptoms. Duration at least 1 day to less than 1 month. Premorbid level of functioning will return, associated with personality disorders Modifiers: 1. With marked stressor - occur shortly after very stressful event 2. With postpartum onset - within 4 weeks postpartum
71
What is Schizoaffective Disorder? (Diagnostic criteria)
1. Period of major depressive or manic episode AND 2. Criteria A for Schizophrenia (full) AND 3. 2+ week period of delusions / hallucinations in absence of major mood symptoms has occurred AND 4. Minimum duration of one month Vs major mood disorder with psychotic features - this two week period will exist
72
What is Delusional Disorder?
Presence of delusions for >1 month in absence of otherwise bizarre behavior and functional deficits. Hallucinations may present if in accordance to delusions -> most commonly persecutory or jealous delusions
73
How is the diagnosis of psychotic disorder due to another medical condition made? What factors would make you lean towards this diagnosis
Prominent hallucinations or delusions with evidence from history, physical exam, or labs which show it is the direct physiological consequence of another medical condition ``` Factors: Atypical age of onset Documented in literature Non-auditory hallucinations (usually visual) Absence of personal or family history ```
74
What psychotic features are associated with amphetamine and cocaine intoxication?
1. Persecutory delusions 2. Distortion of body image 3. Formication 4. Wicked bad nightmares

What type of seizures are alcohol withdrawal seizures, and who is predisposed?
Generalized tonic-clonic with loss of consciousness - > predisposed = hypokalemia, hypomagnesia, epilepsy - > prevent with chlordiazepoxide or lorazepam
76
What is the mechanism of action of Acamprosate? What is it used to treat? How is it excreted?
Second line drug behind naltrexone for treatment of alcohol use disorder Mechanism: NMDA antagonist, GABA-A agonist - "normalizes neurotransmitter systems" -excreted by the kidney, so better in liver problems Topiramate also reduces drinking days
77
How do you treat PCP / Ketamine intoxication?
Keep patients in a calm environment for them to come down | Give benzodiazepines / antipsychotics to calm them

What are the consequences of prolactinemia caused by dopamine blockade going to the infundibulum?
1. Galactorrhea - lactation, even in males 2. Amenorrhea, fertility problems, and sexual dysfunction due to inhibition of FSH / LH 3. Osteoporosis, especially in post-menopausal women
80
What are the EPS from typical antipsychotics and how do you treat all of them?
Parkinsonism: Benztropine Acute dystonia: Anticholinergics once stable, following anticholinergic antihistamine: diphenhydramine Akathisia: Beta blockers, benzos, and anticholinergics
81
How is TD diagnosed? Treated?
1. A 2 measure brief screen - hands out and wiggle the fingers while checking for mouth movements 2. AIMS scale - abnormal involuntary movement Use Valbenazine - a VMAT2 inhibitor preventing the packaging of dopamine in nigrostriatal neurons

Photosensitivity Also weight gain and dyslipidemia / DM like atypicals (especially clozapine and olanzapine)
84
What is the mechanism of action of aripiprazole / brexiprazole / cariprazine? What is the side effect associated with them?
``` D2 partial agonist (blocks dopamine if there's alot) 5HT2A antagonism (accounts for effects) 5HT1A partial agonist -> like buspirone ``` More activating than other antipsychotics
85
Which atypical is thought to have a pro-cognitive effect due to 5HT7 antagonism (like vortioxetine)?
Lurasidone -> lubricates ur brain
86
Why is Risperidone considered like a borderline typical antipsychotic? What drug is an active metabolite of it?
Becomes more like typical above 6mg daily -> EPS side effects - > also raises prolactin even at low doses - > Paliperidone is an active metabolite with fewer side effects
87
What atypical is associated with DRESS (drug reaction with eosinophilia and systemic syndromes)?
Ziprasidone (think of pretty lady with a zipper wearing a DRESS) -> also associated with QT prolongation next to the guide tape, along with Iloperidone
88
What are the major side effects of concern for clozapine other than agranulocytosis?
Myocarditis - heart with a sandglass in it in sketchy Seizures - shaking clock Anticholinergic effects - tea party painting behind clozapine closet -> decreases suicidality like lithium
89
What drug is used for blind patients unable to obtain a normal circadian rhythm?
Tasimelteon (melatonin agonist, same as ramelteon) | -> patients with a non-24 hour sleep-wake disorder
90
What tricyclic is used for treatment of insomnia and why?
Doxepin - strongly anti-H1 effects at low doses
91
What are the two somatic diagnoses when the patient is consciously producing symptoms (lying)?
1. Factitious disorder - patient wants to play the sick role 2. Malingering - patient wants to get something (i.e. drugs, time off work)
92
What are the four somatic diagnoses when the patient will unconsciously produce their symptoms?
1. Somatic symptom - preoccupation with symptoms. Predominant pain is a subtype with long history of medical / surgical care, comorbid OUD and MDD 2. Illness anxiety - preoccupation with disease, somatic symptoms are often absent. 3. Conversion - symptoms appear neurologic and may be motor or sensory. La belle indifference -> doesn't seem to care that they can't feel or move a body part. 4. Pseudocyesis - False belief of being pregnant which is nondelusional and actually associated with objective signs, including abdominal enlargement, reduced menstrual flow / amenorrhea, feeling fetal movement, nausea, breast engorgement / secretions, and labor pains at expected delivery date
93
How do you explain a somatic symptom disorder to a patient?
Explain symptoms are not caused by a serious disease, refrain from confrontation
94
Are patients with Factitious disorder willing to be treated? How will you know they're lying?
Yes -> they will undergo multiple procedures and tamper with test data. Condition is most commonly seen in healthcare workers. You will know they're lying when their condition defies conventional understanding, not responding to usual treatment, and they can predict the course (they are making it up)
95
How should factitious disorder be treated?
Remember that they are MENTALLY ILL - > do not confront, be empathetic - > refer to PCP as a gatekeeper - > avoid unnecessary tests and procedures (basically just ignore it) - > treat underlying mood / anxiety conditions - > monitor your countertransference
96
What personality disorder is closely associated with malingering? How can you tell its probably this?
Antisocial personality disorder -> most likely patient will not be compliant with diagnosis and treatment
97
What two interventions have been shown to decrease suicide mortality? How can we find out if they are going to?
1. Physician education in risk assessment 2. Restriction of lethal means - i.e. less guns available Ask them if they are considering it, and ask them if they have access to the means
98
What family genes are thought to correlate to increased suicide risk?
1. Tryptophan hydroxylase - serotonin production | 2. Serotonin transporter
99
What are the static risk factors for suicide? Include descriptions of these qualifiers.
1. Gender - male - women attempt more, males complete more 2. Age - Increasing age increases risk, but 45-64 is currently highest rate 3. Personal or family history of suicide - genetic 4. Previous events - trauma / abuse 5. Race - being native american / white 6. Marital status - being single
100
What are some mental disorders which increase risk of suicide? Are most suicides tied to mental illness?
90% of suicides are MDD Schizophrenia with increased academic achievement -> will see how much they are going to lose Substance use disorder Anxiety disorder Borderline and Antisocial Personality Disorders (aggressive, impulsive)
