|
Comorbid substance use disorders and anxiety disorders worsen the prognosis of the illness and markedly increase the risk of suicide among patients who are unipolar major depressive and bipolar
|
|
which nt's most implicated in mood disorders?
|
Of the biogenic amines, norepinephrine and serotonin are the two neurotransmitters most implicated in the pathophysiology of mood disorders.
|
|
how is NE related to depression?
what are key receptors? |
The correlation suggested by basic science studies between the downregulation or decreased sensitivity of β-adrenergic receptors and clinical antidepressant responses is probably the single most compelling piece of data indicating a direct role for the noradrenergic system in depression.
presynaptic β2-receptors in depression, because activation of these receptors results in a decrease of the amount of norepinephrine released. Presynaptic β2-receptors are also located on serotonergic neurons and regulate the amount of serotonin released. Venlafaxine also points to role of NE in role of depression. |
|
what data points to serotonin in MDD
|
Besides that SSRIs and other serotonergic antidepressants are effective in the treatment of depression, other data indicate that serotonin is involved in the pathophysiology of depression. Depletion of serotonin may precipitate depression, and some patients with suicidal impulses have low cerebrospinal fluid (CSF) concentrations of serotonin metabolites and low concentrations of serotonin uptake sites on platelets.
|
|
what is role of Dopamine in depression? mania?
|
The data suggest that dopamine activity may be reduced in depression and increased in mania. T
|
|
What is relationship of drugs that decrease DA and mood ds?
|
Drugs that reduce dopamine concentrations—for example, reserpine (Serpasil)—and diseases that reduce dopamine concentrations (e.g., Parkinson's disease) are associated with depressive symptoms
|
|

|
maybe mesolimbic dopamine pathways messsed up?
Dopamine D1 receptor may be HYPOactive in depression |

Suspected to be decreased
|
|

|
Drugs that decrease DA such as reserpine (Serpasil) and diseases that reduce domapine (like Parkinson's) associated with depression.
Also, drugs that increase Dopamine, reduce sx of depression |
|
What drugs increase dopamine concentrations?
|
tyrosine, amphetamine, and bupropion (Wellbutrin)
|
|
Which pathway may be dysfxn in depression related to dopamine?
|
Mesolimbic
|

hypo
|
|
What effect do cholinergic drugs have on mood?
|
Cholinergic Agonists can produce lethargy, anergia, and psychomotor retardation in healthy subjects, can exacerbate symptoms in depression, and can reduce symptoms in mania.
These effects generally are not sufficiently robust to have clinical applications, and adverse effects are problematic. |
|
What is relationship of cholinergic agonists to learned helplessness in mice?
|
Cholinergic agonist and antagonist drugs have differential clinical effects on depression and mania. Agonists can produce lethargy, anergia, and psychomotor retardation in healthy subjects, can exacerbate symptoms in depression, and can reduce symptoms in mania. These effects generally are not sufficiently robust to have clinical applications, and adverse effects are problematic.
|
|
What is relationship of depression and cholinergic agonists?
|
Cholinergic agonists can induce changes in hypothalamic-pituitary adrenal (HPA) activity and sleep that mimic those associated with severe depression.
Some patients with mood disorders in remission, as well as their never-ill first-degree relatives, have a trait-like increase in sensitivity to cholinergic agonists. |
|
Is there relationship with GABA and depression? What is it?
|
Reductions of GABA have been observed in plasma, CSF, and brain GABA levels in depression.
Animal studies have also found that chronic stress can reduce and eventually can deplete GABA levels. By contrast, GABA receptors are upregulated by antidepressants, and some GABAergic medications have weak antidepressant effects. |
|
Is there relationship between Glutamate and Depression? What is it?
|
Glutamate, thus, may work in conjunction with hypercortisolemia to mediate the deleterious neurocognitive effects of severe recurrent depression. Emerging evidence suggests that drugs that antagonize NMDA receptors have antidepressant effects.
|
|
What is bio relationship of stress and depression?
|
Glutamate, thus, may work in conjunction with hypercortisolemia to mediate the deleterious neurocognitive effects of severe recurrent depression. Emerging evidence suggests that drugs that antagonize NMDA receptors have antidepressant effects.
|
|
Stress is associated how to HPA axis?
|
Elevated HPA activity is a hallmark of mammalian stress responses and one of the clearest links between depression and the biology of chronic stress.
|
|
In depression, what levels of cortisol is seen and what does it suggest?
|
Hypercortisolema in depression suggests one or more of the following central disturbances:
decreased inhibitory serotonin tone; increased drive from norepinephrine (NE), ACh, or corticotropin releasing hormone (CRH); or decreased feedback inhibition from the hippocampus. |
|
hypercortisolema in depression is associated how with
1. inhibitory serotonin tone, 2. drive from NE, ACh, CRH 3. feedback inhibition from hippocampus? |
1. decreased
2. increased 3. decreased |
|
HPA activity is increased in what % of depressed outpatients? inpatients?
|
Evidence of increased HPA activity is apparent in 20 to 40 percent of depressed outpatients and 40 to 60 percent of depressed inpatients
|
|
How is Dexamathosone used?
i.e. what is normal, abnormal response |
normally suppresses HPA axis activity for 24 hours
Nonsuppression of cortisol secretion at 8:00 AM the following morning or subsequent escape from suppression at 4:00 PM or 11:00 PM is indicative of impaired feedback inhibition. Hypersecretion of cortisol and dexamethasone nonsuppression are imperfectly correlated (approximately 60 percent concordance). A more recent development to improve the sensitivity of the test involves infusion of a test dose of CRH after dexamethasone suppression. |
|
Why are the tests of adrenocortical hyperactivity not used?
|
These tests of feedback inhibition are not used as a diagnostic test because adrenocortical hyperactivity (albeit usually less prevalent) is observed in mania, schizophrenia, dementia, and other psychiatric disorders
|
|
What Percent of depressed patients have thyroid dysfxn? How does it show?
|
Approximately 5 to 10 percent of people evaluated for depression have previously undetected thyroid dysfunction
Increased TSH |
|
What is TRH challenge?
|
increased TSH response to a 500-mg infusion of the hypothalamic neuropeptide thyroid-releasing hormone (TRH).
|
|
What % of depressed patient show abnormal response to TRH challenge?
|
depressed patients (e.g., 20 to 30 percent) shows a blunted TSH response to TRH challenge.
|
|
What is clinical meaning does a blunted TSH response mean?
|
the major therapeutic implication of a blunted TSH response is evidence of an increased risk of relapse despite preventive antidepressant therapy
|
|
Does the dexamethasone suppression test normalize with tx?
|
No
|
|
Does the blunted TSH response to TRH normalize to treatment?
|
No
|
|
Somostatin levels and relation to mood ds?
|
Growth hormone (GH) is secreted from the anterior pituitary after stimulation by NE and Dopamine (DA). Secretion is inhibited by somatostatin, a hypothalamic neuropeptide, and CRH. Decreased CSF somatostatin levels have been reported in depression, and increased levels have been observed in mania
|
|
What causes release of prolactin from pituitary? what inhibits?
|
serotonin
dopamine |
|
Any relation of prolactin to depression?
|
Most studies have not found significant abnormalities of basal or circadian prolactin secretion in depression, although a blunted prolactin response to various serotonin agonists has been described. This response is uncommon among premenopausal women, suggesting that estrogen has a moderating effect.

Define REM latency
|
The combination of increased REM drive and decreased slow wave sleep results in a significant reduction in the first period of non-REM (NREM) sleep, a phenomenon referred to as reduced REM latency
|
|
Relationship of REM latency and slow wave sleep after recovery of depressive episode?
|
Reduced REM latency and deficits of slow wave sleep typically persist after recovery of a depressive episode.

|
intrusive ruminations
|
|
Which brain areas are considered heavily involved in depression?
|
prefrontal cortex
anterior cingulate hippocampus amygdala |
|
prefrontal cortex function?
|
The PFC is viewed as the structure that holds representations of goals and appropriate responses to obtain these goals
Subregions in the PFC appear to localize representations of behaviors related to reward and punishmen |
|
prefrontal cortext function in left-hemi versus right hemi?
|
left-sided activation of regions of the PFC is more involved in goal-directed or appetitive behaviors, whereas regions of the right PFC are implicated in avoidance behaviors and inhibition of appetitive pursuits
|
|
Anterior Cingulate Cortex function?
|
The anterior cingulate cortex (ACC) is thought to serve as the point of integration of attentional and emotional inputs
|
|
What are the subdivisions of the Anterior Cingulate Cortex and their function?
|
Two subdivisions have been identified: an affective subdivision in the rostral and ventral regions of the ACC and a cognitive subdivision involving the dorsal ACC.
|
|
What does activation of the Anterior Cingulate Cortex help people with?
|
control of emotional arousal, particularly when goal attainment has been thwarted or when novel problems have been encountered.
|
|
Hippocampus function?
|
The hippocampus is most clearly involved in various forms of learning and memory, including fear conditioning, as well as inhibitory regulation of the HPA axis activity. Emotional or contextual learning appears to involve a direct connection between the hippocampus and the amygdala
|
|
Amygdala function
|
The amygdala appears to be a crucial way station for processing novel stimuli of emotional significance and coordinating or organizing cortical responses
Although most research has focused on the role of the amygdala in responding to fearful or painful stimuli, it may be ambiguity or novelty, rather than the aversive nature of the stimulus per se, that brings the amygdala on line |
|
What do family studies show about mood disorders?
|
Family data indicate that if one parent has a mood disorder, a child will have a risk of between 10 and 25 percent for mood disorder. If both parents are affected, this risk roughly doubles.

|
|
What is the theory explaining why stressful life events often precede the first episode of a mood disorder but not so much 2nd, 3rd episodes?
|
The stress that comes from the first episode results in long-lasting changes in the brains biology; i.e., changes brain to be more vulnerable so that can depressed without an external stressor

|
Freud/Karl Abraham
1. infant-mother relationship 0 to 18 months ... disturbed (oral phase) ... this creates vulnerability to depression 2. depressed linked to real or imagined object loss 3. lost/departed object is introject as a defense (to minimize distress associated with loss) 4. lost object seen with mix of love and hate, feelings of anger are directed inward to self. Overall, depression = aggresssion toward oneself |
|
Silvano Arieti view on depression
|
Silvano Arieti observed that many depressed people have lived their lives for someone else rather than for themselves. He referred to the person for whom depressed patients live as the dominant other, which may be a principle, an ideal, or an institution, as well as an individual
Depression sets in when patients realize that the person or ideal for which they have been living is never going to respond in a manner that will meet their expectations. |
|
Edward Bibring view on depression
|
Edward Bibring regarded depression as a phenomenon that sets in when a person becomes aware of the discrepancy between extraordinarily high ideals and the inability to meet those goals
|
|
Edith Jacobson view on depression
|
Edith Jacobson saw the state of depression as similar to a powerless, helpless child victimized by a tormenting parent.
|
|
Heinz Kohut view of depression
|
Heinz Kohut's conceptualization of depression, derived from his self-psychological theory, rests on the assumption that the developing self has specific needs that must be met by parents to give the child a positive sense of self-esteem and self-cohesion. When others do not meet these needs, there is a massive loss of self-esteem that presents as depression.
|
|
John Bowlby view of depression
|
John Bowlby believed that damaged early attachments and traumatic separation in childhood predispose to depression. Adult losses are said to revive the traumatic childhood loss and so precipitate adult depressive episodes.
|
|
What is psychodynamic view of mania?
|
defense against depression
|
|
Abraham view of mania?
|
Abraham, for example, believed that the manic episodes may reflect an inability to tolerate a developmental tragedy, such as the loss of a parent. The manic state may also result from a tyrannical superego, which produces intolerable self-criticism that is then replaced by euphoric self-satisfaction.
|
|
Bertram Lewin view of mania
|
Bertram Lewin regarded the manic patient's ego as overwhelmed by pleasurable impulses, such as sex, or by feared impulses, such as aggression.
|
|
Klein view of mania?
|
Klein also viewed mania as a defensive reaction to depression, using manic defenses such as omnipotence, in which the person develops delusions of grandeur.
|
|
What is Aaron Beck triad view of depression?
|
Aaron Beck postulated a cognitive triad of depression that consists of (1) views about the self—a negative self-precept; (2) about the environment—a tendency to experience the world as hostile and demanding, and (3) about the future—the expectation of suffering and failure
|
|
What is learned helplessness view of depression?
|
In the reformulated view of learned helplessness as applied to human depression, internal causal explanations are thought to produce a loss of self-esteem after adverse external events. Behaviorists who subscribe to the theory stress that improvement of depression is contingent on the patient's learning a sense of control and mastery of the environment.
|
|
How stable is the diagnosis of depression?
|
One type of study assessed the stability of a diagnosis of major depression in a patient over time. The study found that 25 to 50 percent of the patients were later reclassified as having a different psychiatric condition or a nonpsychiatric medical condition with psychiatric symptoms

bipolar
|
|
How much minimum time is needed between mood episodes to consider then seperate?
|
At least two months without significant symptoms

What is the difference between mood congruent and mood incongruent psychosis?
|
Mood congruent usually means more likely mood ds while incongruent means Szaffective/Sz
|
|
What has been associated with poor prognosis in mood disorders (along with psychosis)
|
long duration of episodes, temporal dissociation between the mood disorder and the psychotic symptoms, and a poor premorbid history of social adjustment. The presence of psychotic features also has significant treatment implications.
|
|
Melancholia features?
|
by severe anhedonia,
early morning awakening, weight loss, and profound feelings of guilt (often over trivial events) |
|
Melancholia associated with biology?
|
yes, changes in autonomic and endocrine function
|
|
Does melancholia occur more with life stressors or not?
|
more endogenous, without external life stresors
|
|
What are atypical features of depression?
|
reversed veg s:
increased eating and sleeping |
|
How to patients with MDD atypical features compare with MDD typical features?
|
When patients with major depressive disorder with atypical features are compared with patients with typical depression features, the patients with atypical features are found to have a younger age of onset, more severe psychomotor slowing, and more frequent coexisting diagnoses of panic disorder, substance abuse or dependence, and somatization disorder.
Patients with atypical features may also have a long-term course, a diagnosis of bipolar I disorder, or a seasonal pattern to their disorder. |
|
How are these patients often misdiagnosed?
|
The high incidence and severity of anxiety symptoms in patients with atypical features have sometimes been correlated with the likelihood of their being misclassified as having an anxiety disorder rather than a mood disorder.
|
|
What are the key features of catatonia and when do you see them?
|
The hallmark symptoms of catatonia—stuporousness, blunted affect, extreme withdrawal, negativism, and marked psychomotor retardation—can be seen in both catatonic and noncatatonic schizophrenia, major depressive disorder (often with psychotic features), and medical and neurological disorders

1. Too low
2. Too short |
|
When would you consider drug trial unsuccessful?
|
Max tolerated dose at 4 to 5 weeks
|
|
What would you do if patient improving on low dosage of drug?
|
Don't increase (at least wait until max benefit achieved); i.e., if improving, watchi.
|
|
If no response at all after 2 to 3 weeks what can be done?
|
Drug level ... may tell adherence or unusual pharmacokinetics
|
|

Tx prophylactically for 5 years
|
|
How do available antidepressants differ in overall efficacy, speed of response, or long-term effectiveness.
|
They don't
|
|
What do antidepressants differ in?
|
Side effect profile
interactions side effects chance of discontinuation syndrome ease of dose adjustment |
|
How do you select intial Rx?
|
Selection of the initial treatment depends on the chronicity of the condition,
course of illness (a recurrent or chronic course is associated with increased likelihood of subsequent depressive symptoms without treatment), family history of illness and treatment response, symptom severity, concurrent general medical or other psychiatric conditions, prior treatment responses to other acute phase treatments, potential drug–drug interactions, and patient preference. |
|
What % of uncomplicated MDD respond to Rx?
|
In general, approximately 45 to 60 percent of all outpatients with uncomplicated (i.e., minimal psychiatric and general medical comorbidity), nonchronic, nonpsychotic major depressive disorder who begin treatment with medication respond (i.e., achieve at least a 50 percent reduction in baseline symptoms);
|
|
How is response defined?
|
50% reduction in baseline sx
|
|
What percent achieve Remission, absensce of depressive symptoms?
|
up to 50% (35-50%)
|
|
Patients with major depressive disorder with atypical features (sometimes called hysteriod dysphoria) may preferentially respond to treatment with
|
MAOIs or SSRIs.
|
|
How about melancholic depression, which drug to use?
|
Antidepressants with dual action on both serotonergic and noradrenergic receptors demonstrate greater efficacy in melancholic depressions
|
|
Tx of MDD with psychotic features
|
add antipsychotic
use ECT |
|
Which rx for atypical features of depression?
|
For those with atypical symptom features, strong evidence exists for the effectiveness of MAOIs
SSRI's and bupropion also usable in atypical depression |
|
Tx of MDD with comorbid Panic Ds, which Rx?
|
SSRI
tricyclics |
|
In comorbid MDD, what decides choice of treatment, MDD or the comorbidity
|
the comorbidity
|
|
Which GMC diseases does MDD worsen morb and mort?
|
The presence of a major depressive episode is associated with increased morbidity or mortality of many general medical conditions (e.g., cardiovascular disease, diabetes, cerebrovascular disease, and cancer
|
|
Is it useful to use antidepressants side effects to treat depression sx?
|
No.
Choosing more sedating antidepressants (e.g., amitriptyline [Elavil, Endep]) for more anxious, depressed patients or more activating agents (e.g., desipramine) for more psychomotor-retarded patients is not generally helpful. For example, any short-term benefits with paroxetine, mirtazapine, or amitriptyline (more sedating drugs) on symptoms of anxiety or insomnia may become liabilities over time. |
|
So how should you manage sx relief?
|
use adjunctive medications (e.g., sleeping pills or anxiolytics) combined with antidepressants to provide more immediate symptom relief or to cover those side effects to which most patients ultimately adapt
|
|
What factors might help you in choosing rx?
|
failure to previous class well documented

|
What is psychodynamic theory of cyclothymia?
|
Most psychodynamic theories postulate that the development of cyclothymic disorder lies in traumas and fixations during the oral stage of infant development. Freud hypothesized that the cyclothymic state is the ego's attempt to overcome a harsh and punitive superego. Hypomania is explained psychodynamically as the lack of self-criticism and an absence of inhibitions occurring when a depressed person throws off the burden of an overly harsh superego. The major defense mechanism in hypomania is denial, by which the patient avoids external problems and internal feelings of depression.
Hypomania is frequently triggered by a profound interpersonal loss. The false euphoria generated in such instances is a patient's way to deny dependence on love objects and simultaneously disavowing any aggression or destructiveness that may have contributed to the loss of the loved person |

Describe Anxiety-Blissfulness Psychosis
|
Anxiety-blissfulness psychosis may resemble agitated depression but can also be characterized by so much inhibition that a patient can hardly move. Periodic states of overwhelming anxiety and paranoid ideas of reference are characteristic of the condition, but self-accusation, hypochondriacal preoccupation, other depressive symptoms, and hallucinations may also accompany it. The blissful phase manifests most frequently in expansive behavior and grandiose ideas, which are concerned less with self-aggrandizement than with the mission of making others happy and saving the world.
