Then, she still kept functional recovery. 6 Possible Dose-Side Effect Relationship of Antipsychotic Drugs: Relevance to Cognitive Function in Schizophrenia Cognitive function, such as verbal learning memory, working memory, executive function, verbal fluency and attention/information processing, is the most influential determinant of outcome in patients with schizophrenia. Atypical antipsychotic drugs have been shown to be more efficacious in treating cognitive disturbances of schizophrenia compared with typical antipsychotic drugs. Serotonin (5-hydroxytryptamine [5-HT]) receptor subtypes, such as the 5-HT1A receptor, are considered to mediate the ability of antipsychotic drugs to enhance cognition. On the other hand, treatment with some atypical agents, such as risperidone, may deteriorate working memory in some people with early-stage schizophrenia. The paradoxical side effects of these antipsychotic drugs in terms of cognition may be attributable to dose, duration of treatment and type of cognitive domain. Expert Rev Clin Pharmacol. 2008;1(6):791-802. Clinical Staging of Psychotic or Mood disorder St. Definition 0 Increased risk of psychotic or severe mood disorder. No symptoms currently. 1a Mild or non-specific symptoms, including neurocognitive deficits of psychosis or severe mood disorder. Mild functional change or decline. 1b Ultra high risk: moderate but subthreshold symptoms, with moderate neurocognitive changes and functional decline to caseness (Global Assessment of Functioning [GAF] < 70) 2 First episode of psychotic or severe mood disorder. Full threshold disorder with moderatesevere symptoms, neurocognitive deficits and functional decline (GAF 30-50) 3a Incomplete remission from first episode of care. Could be linked or fast-tracked to Stage 4. 3b Recurrence of relapse of psychotic or mood disorder which stabilizes with treatment at a level of GAF, residual symptoms, or neurocognition below the best level achieved following remission from first episode. 3c Multiple relapses, provided worsening in clinical extent and impact of illness is objectively present. 4 Severe, persistent or unremitting illness as judged on symptoms, neurocognition and disability criteria.

Co-morbid substance use disorder and anxiety disorder, presence of somatic illness, external mastery, low social support and high baseline functioning were predictors of worsened functioning. Journal of Affective Disorders 82 (2004) 363–371 Major depressive disorder: psychosocial impairment and key considerations in functional improvement. Patients who achieve full asymptomatic remission from depressive symptoms can still experience functional impairment; thus, restoring psychosocial functioning is increasingly being identified as an important goal of depression therapy. The more effective the therapeutic approach employed to resolve symptoms of depression (eg, long-term duration of treatment, monitoring of patient adherence to treatment, maintenance of asymptomatic remission), the more likely it is that patients with MDD will experience a full restoration of premorbid psychosocial functioning.

The length of the current untreated episode of illness may be the strongest predictor of overall short-term and long-term outcome in major depression.*1 The slow response of antidepressant treatment is connected with suicidality. Achieving a more rapid and enhanced treatment response, targeting core depressive symptoms including hopelessness, could help to substantially reduce the incidence.*2 Limits quality of life, particularly through its impairment of the cognitive skills necessary for work, creating and maintaining relationships, being productive, and functioning in multiple domains.*3 Increases the patient’s subjective experience of a lack of treatment efficacy, which may lead to frustration and damage to the patient doctor relationship, usually finally resulting in poor compliance rates.*4 *1 Bagby RM, Ryder AG, Cristi C.

Consideration of metabolic risk when starting SGA If a patient gains ≥5% of his or her initial weight during therapy, one should consider switching the SGA If a patient develops worsening glycaemia or dyslipidaemia while on antipsychotic therapy, one should consider switching to an SGA that has not been associated with weight gain or diabetes Non-pharmacological strategies Psychotherapy (often in conjunction with pharmacotherapy), CBT/ interpersonal psychotherapy Electroconvulsive therapy (ECT) Vagus nerve stimulation (VNS). The US FDA recently approved vagus nerve stimulation as adjunctive therapy (after four prior treatment failures); however, its benefits are seen only after prolonged (up to 1 year) use. Other nonpharmacological options, such as repetitive transcranial stimulation, deep brain stimulation or psychosurgery, remain experimental and are not widely available. Therapeutic options for treatment-resistant depression. CNS Drugs. 2010 Feb;24(2):131-61. Clinical experience tells us that such treatment-resistant patients are difficult to manage when the next depressive episode appears, because the previous treatment history causes both the patient and the clinician to develop treatment strategies that include more intensive methods of treatment (ie, higher doses, drug combinations, augmentation strategies, etc). Thus, in addition to biological treatment, psychosocial interventions (cognitive behavioral therapy, emotion-focused therapy, self esteem therapy) should be recommended.

A Metaanalysis of Studies of Newer Agents Methods:Medline/Pubmed, EMBase, clinical trial registries, program syllabi from major psychiatric meetings held since 1995, and documents from relevant pharmaceutical companies were searched for double-blind, randomized trials comparing a newer serotonergic-noradrenergic antidepressant drug (venlafaxine, duloxetine, milnacipran, mirtazapine, mianserin, or moclobemide) with an SSRI for MDD. Results:Ninety-three trials (n = 17,036) were combined using a random-effects model. Treatment with serotonergic + noradrenergic antidepressant drugs was more likely to result in clinical response than the SSRIs (risk ratio [RR] = 1.059; response rates 63.6% versus 59.3%; p = .003). Conclusions:Serotonergic-noradrenergic antidepressant drugs seem to have a modest efficacy advantage compared with SSRIs in MDD. With the Number Needed to Treat (NNT) statistic as one indicator of clinical significance, nearly 24 patients would need to be treated with dual-action antidepressant drugs instead of SSRIs in order to obtain one additional responder.

The principal difference between these treatment was the sexual dysfunction complicated SSRI therapy, whereas bupropion and placebo not.

Reduced somatodendritic and postsynaptic 5-HT1A receptor numbers or affinity have been reported in some post-mortem studies of suicide victims, a result consistent with well-replicated PET analyses demonstrating reduced 5-HT1A receptor binding potential in diverse regions such as the dorsal raphe, medial prefrontal cortex (mPFC), amygdala and hippocampus. 5-HT1A receptor knockout (KO) mice display increased anxiety-related behavior, which, unlike in their wild-type counterparts, cannot be rescued with AD treatment. In humans, the G allele of a single nucleotide polymorphism (SNP) in the 5HT1A receptor gene (HTR1A; rs6295), which abrogates a transcription factor binding site for Deaf-1 and Hes5, has been reported to be over-represented in MDD cases. Conversely, the C allele has been associated with better response to AD drugs. We raise the possibility that 5-HT1A receptor dysfunction represents one potential mechanism underpinning MDD and other stress-related disorders.

Atypical antipsychotic drugs have been shown to be more efficacious in treating cognitive disturbances of schizophrenia compared with typical antipsychotic drugs. Serotonin (5-hydroxytryptamine [5-HT]) receptor subtypes, such as the 5-HT1A receptor, are considered to mediate the ability of antipsychotic drugs to enhance cognition. On the other hand, treatment with some atypical agents, such as risperidone, may deteriorate working memory in some people with early-stage schizophrenia. The paradoxical side effects of these antipsychotic drugs in terms of cognition may be attributable to dose, duration of treatment and type of cognitive domain.

The presence of rumination across these various disorders suggests that rumination is a trans-diagnostic process (Abbott and Rapee, 2004; American Psychiatric Association, 1994; Ehlers et al., 1998; Van Oppen et al., 1995). * Additionally, several prospective longitudinal studies have shown that rumination predicts levels of both anxiety and depressive symptoms (Hong, 2007; Nolen-Hoeksema, 2000;Sarin et al., 2005). * One such study by Johnson et al. (2008) found that both undergraduates diagnosed with bipolar disorder and those diagnosed with MDD experienced heightened levels of rumination.

Specifically, when dopamine levels are limited, activation of brain regions tends to be more diffuse than concentrated (e.g., Bush, 2010). Presumably, if dopamine levels are low, brain activation is significantly dependent upon random noise--that is, fleeting states, thoughts, or conditions--rather than more sustained patterns of cognition. Therefore, many regions of the brain are activated marginally. In contrast, if dopamine levels are high, specific cognitions prevail, and activation is more confined to particular regions. Bush, G. (2010). Attention-deficit/hyperactivity disorder and attention networks. Neuropsychopharmacology, 35, 278-300. 59 Rumination and Dopamine(2) Diffuse rather than concentrated activation can undermine the efficiency of some brain regions. To illustrate, the left inferior frontal gyrus, which primarily overlaps with the ventrolateral prefrontal cortex, partly underpins the inhibition of unwanted thoughts. As Berman et al. (2011) showed, when activation in this region was diffuse rather than concentrated to specific locations, people could not inhibit negative words as effectively. Presumably, this diffuse activation implies the individuals cannot focus on specific classes of stimuli efficiently. They attempt to inhibit a broad range of stimuli, compromising efficiency. This limitation could underpin the rumination that characterizes depression. In particular, dopamine is often limited in depressed individuals (e.g., Hasler et al., 2008). Thus, activation of specific regions, such as the left inferior frontal gyrus, may be more diffuse. Negative thoughts, therefore, cannot be as readily inhibited. Berman, M. G, Nee, D.

We modified CBT to target rumination because rumination: (a) remains elevated after remission from depression; (b) is associated with less treatment response; and (c) prospectively predicts the onset, severity and duration of depression. The British Journal of Psychiatry (2011) 199, 317–322. Conclusion 1. Around 60% of patients do not achieve remission after treatment by first-line antidepressants. 2. The target goal of treatment for MDD should be functional recovery, emphasizing timing, active treatment of residual s/s, side effects and duration. 3. Understanding non-response of antidepressant, emphasizing dosage, duration and drug adherence. 4. Augmentation or switch strategy: Considering the advantages, disadvantages, evidence and indication. 5. The Role of SGA for augmentation treatment: As more evidence confirmed, choosing the good candidate, intervening earlier and monitoring the related side effects might be warranted. 6. The mechanism of SGA for TRD remained to be further studied, esp. the role of 5-HT1A receptor, dopamine and rumination.
