CAP5 Flashcards
Define affective instability
Emotional dysregulation as exaggerated reactions to negative or frustrating stimuli (unlike in impulsivity there is a rush of affect)
Emotional regulation involves what circuitry?
Orbital frontal cortex, amygdala, anterior cingulate, cerebellum (temporal)
What brain structures are involved in anxiety/hyperarousal?
Limbic system perceives stress resulting in the hypothalamus releasing CRF which stimulates the pituitary to release ACTH which stimulates the adrenals to release glucocorticoids. CRF = corticotropin releasing factor. ACTH = adrenocorticotrophic hormone
Acute stimulation of 5HT2a in the brainstem leads to what?
Myoclonus, disrupted slow wave sleep, and nocturnal awakenings
What is the data on tricyclic antidepressants in ADHD?
They are effective, albeit more for behavior than cognition perhaps
What percentage of those with Tourette’s disorder have ADHD?
For those 6 to 18 years old, 50 to 60% (Cohen and Leckman 1989)
What is noradrenergic deficiency syndrome?
Depression that is associated with fatigue, apathy, notable cognitive disturbance, impaired concentration, problems with sustaining and focusing attention, slow information processing, and decreased working memory
Acute stimulation of 5HT2a in the mesocortical pleasure center leads to what?
Decreased dopamine, which can lead to apathy or decreased libido
Acute stimulation of 5HT2a in the spinal cord leads to what?
Inhibition of the spinal reflexes of orgasm and ejaculation
Acute stimulation of 5HT2a in the basal ganglia leads to?
Akathisia, psychomotor retardation or agitation, parkinson’s, dystonia (because serotonin inhibits dopamine release)
Acute stimulation of 5HT2a and 2c in the projection from the raphe nuclei to the limbic cortex results in?
Acute mental agitation, anxiety, panic attacks
Projection of 5HT neurons from the raphe nuclei to which area leads to therapeutic action?
Frontal cortex
What does the presence of serotonin in the synaptic space lead to?
Postsynaptic receptors become desensitized (2a, 2c, 3). These receptors send information to the cell nucleus of the postsynaptic neuron resulting in the instruction to downregulate these receptors. The time course for this to happen corresponds to the tolerance of side effects.
The increased ratio of serotonin to serotonin receptors after antidepressant treatment as a mechanism of action is supported by what evidence among other?
Deceased suicidal and otherwise depressed patients have had more 5-HT2A receptors than normal patients. These considerations suggest that 5-HT2A overactivity is involved in the pathogenesis of depression.
What serotonin receptor does trazadone block?
5HT2a receptor. It also blocks reuptake but less so than other agents
By what process does trazodone effet sleep?
By inhibiting histamine H1 leading to sedation and by inhibiting 5HT2a which induces and restores slow wave sleep
When selective serotonin reuptake inhibitor treatment is initiated where does serotonin first rise?
Cell bodies in the raphe nuclei and not at the axon terminal where the re-uptake pump is located (somatodendritic autoreceptors 5HT1a)
Increased serotonin at the somatodendritic autoreceptor 5HT1a leads to?
Downregulation and densitization. Once desensitized and down regulated it can no longer efffectively inhibit its own release and the serotonin neuron is disinhibited. This correlates with time of onset of anti-depressant action
Mirtazapine blocks which alpha receptors?
Alpha 2
Mirtazapine inhibits which serotonin and histamine receptors?
2a, 2c, 3, H1
Mirtazapine’s blockade of which receptor contributes to its antidepressant effect?
5HT2a
Mirtazapine’s blockade of which receptors leads to anxiolysis and relaxation?
5HT2a, 5HT2c and H1
Mirtazapine’s blockade of which receptors mitigates side effects?
5HT2a, 5HT2c, 3
Mirtazapine’s blockade of which receptors leads to sedation?
5HT2a and H1
Mirtazapine’s blockade of which receptors leads to weight gain?
5HT2c and H1
Mirtazapine’s blockade of 5HT2a, 5HT2c, and 5HT3 leads to preferential stimulation of which receptor?
5HT1a and therefore anxiolysis, antidepressant effects
How does alpha 2 antagonism increase the release of serotonin?
The locus coeruleus has norepinephrine neurons stimulating alpha 1 receptors in the midbrain which stimulates release of serotonin. When alpha 2 is antagonized this disinhibits release of norepinephrine. The norepinephrine stimulates alpha 1 which stimulates serotonin release
What is the most significant parental factor in the incidence of child psychopathology?
Presence of conduct disorder in one or both parents (Rutter and Quinton)
What is the general outcome for gifted (IQ 130-150) individuals who are deaf?

25%
What are some easy ‘physical exam’ tests for problems with the frontal lobes?
- Smooth pursuit: follow finger smoothly, left to right. Abnormal is discontinuous jerks (saccadic) or deviation (looking away). 2. Tapping forehead. If tap = or > 3 times and blinking persists, it suggests inflexibility 3. Antisaccade test: 5x: 2x left, 2x right, 1x left 3. 2 stepped Luria, palm, fist hand. The most sensitive and specific are the smooth pursuit and the Luria.
Describe the 3 step Luria task, used to explore frontal lobe probolems?
With fingers fully extended and the patient following, the examiner places his right hand with a cutting motion on his right knee or on a table, then in a fist with the knuckles down, and then palm down with fingers extended. Examiner and patient then repeat this three more times. The hand motions could be reinforced by counting from 1 to 3 along with each segment, or by saying “cut, fist, and slap.” Patients are then asked to repeat the movements unguided by the examiner A score of 0 is recorded if the patient is unable to mimic the movement or complete three independent cycles. Performance on the Luria test is scored as normal or abnormal. The test is judged to be abnormal if the hand motions differed in type or sequence from that of the examiner. A common error was having the fingers flexed instead of extended for the first movement. (Weiner et al. 2011)
Describe the antisaccade test
The examiner faces the patient, holds his or her hands to either side of the patient’s eyes, and asks the patient to look at the examiner’s nose. She instructs the patient to deviate her eyes to the side of the examiner’s briefly raised index finger and then return his or her gaze to the examiner’s nose. Alternately, the examiner moves her right and then left index fingers. The patient looks towards the moving finger and then back at the examiner’s nose. Once it is clear to the examiner that the patient has mastered this and looks to the moving finger and then back to the examiner’s nose, the examiner asks the patient to look toward the opposite side, toward the side that does not move. Patients with frontal damage have trouble suppressing the urge to look at the moving finger and first look there before correcting. This test uncovers impulsivity and inattentiveness in children. It is performed five times, twice to the left, twice to the right, and then once to the left. Two or more failures count as an error. (Lewis et al. 2002)
Describe the smooth pursuit task to explore frontal lobe function
The examiner asks the patient to follow the examiner’s smoothly moving finger as it goes slowly from left to right horizontally in front of the patient. An abnormal response would be visual tracking in brief, staccato, discontinuous (saccadic) jerks or inattentiveness with brief deviations of the patient’s eyes from the examiner’s finger rather than smooth movements. A normal response would be smooth visual tracking of the moving finger. The patient should also be able to stare for 30 seconds at the examiner’s stationary finger without deviating his or her gaze. This helps to demonstrate an ability to concentrate. (Lewis et al. 2002)

It comes in three forms, for different age groups, and comprises 40 incomplete sentences, usually only 1-2 words long such as “I regret …”. The subject is asked to complete the sentence. It is a projective test.
What are the instructions for the Machover Draw-A-Person ?
In administering the DAP, the examiner always starts by providing the examinee with a blank sheet of paper and a pencil with eraser. The examiner then instructs the examinee to ‚Äúdraw a person‚Äù, thus, the name of the test. After drawing one person, the examinee then proceeds to draw another person of the opposite sex with the first one. The exam ends with the examinee narrating a story that features the figures he or she has drawn as characters. The figure of the same sex with that of the examinee is seen to be reflective of impulses the examinee finds acceptable while the unacceptable instincts are portrayed by the figure of the opposite sex Use 8 1/2 x 11” paper; pencil and eraser.
