RESUMO

Catatonia is a syndrome heterogeneous with regard to presentation and etiology. Electroconvulsive therapy (ECT) remains the first-line treatment for catatonia. Literature review reveals only a few published case reports on the use of right unilateral (RUL) ECT in catatonia, 1 case report on ultrabrief RUL ECT, and an absence of evidence on the relative effectiveness and tolerability of RUL versus bilateral ECT in treating catatonia. In contrast, there are multiple reports in the literature of robustly dosed bilateral ECT, often administered on consecutive days. Reasons for choosing this intervention over the better-tolerated RUL treatment include assumptions about its relative speed and/or breadth of efficacy. Here we present a case series of 13 catatonic patients treated in an academic center over the course of the last 3 years. Our experience suggests that ultrabrief RUL ECT can rapidly and effectively treat catatonia from diverse etiologies.

RESUMO

BACKGROUND: The objective was to examine functional connectivity linked to the auditory system in patients with bothersome tinnitus. Activity was low frequency (< 0.1 Hz), spontaneous blood oxygenation level-dependent (BOLD) responses at rest. The question was whether the experience of chronic bothersome tinnitus induced changes in synaptic efficacy between co-activated components. Functional connectivity for seed regions in auditory, visual, attention, and control networks was computed across all 2 mm(3) brain volumes in 17 patients with moderate-severe bothersome tinnitus (Tinnitus Handicap Index: average 53.5 ± 3.6 (range 38-76)) and 17 age-matched controls. RESULTS: In bothersome tinnitus, negative correlations reciprocally characterized functional connectivity between auditory and occipital/visual cortex. Negative correlations indicate that when BOLD response magnitudes increased in auditory or visual cortex they decreased in the linked visual or auditory cortex, suggesting reciprocally phase reversed activity between functionally connected locations in tinnitus. Both groups showed similar connectivity with positive correlations within the auditory network. Connectivity for primary visual cortex in tinnitus included extensive negative correlations in the ventral attention temporoparietal junction and in the inferior frontal gyrus and rostral insula - executive control network components. Rostral insula and inferior frontal gyrus connectivity in tinnitus also showed greater negative correlations in occipital cortex. CONCLUSIONS: These results imply that in bothersome tinnitus there is dissociation between activity in auditory cortex and visual, attention and control networks. The reciprocal negative correlations in connectivity between these networks might be maladaptive or reflect adaptations to reduce phantom noise salience and conflict with attention to non-auditory tasks.

RESUMO

OBJECTIVES: To test the hypothesis that the degree of vascular burden and/or age of onset may influence the degree to which cognition can improve during the course of treatment in late-life depression. DESIGN: Measurement of cognition both before and following 12 weeks of treatment with sertraline. SETTING: University medical centers (Washington University and Duke University). PARTICIPANTS: One hundred sixty-six individuals with late-life depression. INTERVENTION: Sertraline treatment. MEASUREMENTS: The cognitive tasks were grouped into five domains (language, processing speed, working memory, episodic memory, and executive function). We measured vascular risk using the Framingham Stroke Risk Profile measure. We measured T2-based white matter hyperintensities using the Fazekas criteria. RESULTS: Both episodic memory and executive function demonstrated significant improvement among adults with late-life depression during treatment with sertraline. Importantly, older age, higher vascular risk scores, and lower baseline Mini-Mental State Examination scores predicted less change in working memory. Furthermore, older age, later age of onset, and higher vascular risk scores predicted less change in executive function. CONCLUSIONS: These results have important clinical implications in that they suggest that a regular assessment of vascular risk in older adults with depression is necessary as a component of treatment planning and in predicting prognosis, both for the course of the depression itself and for the cognitive impairments that often accompany depression in later life.

RESUMO

In this pilot study we assessed the efficacy of olanzapine as monotherapy in the treatment of major depressive disorder, without psychosis. We also demonstrated the in vivo 5-HT2A receptor occupancy of olanzapine using positron emission tomography. An open-label prospective 6-week study design with 14 patients who met the inclusion and exclusion criteria for the study were enrolled from the general community of the St. Louis metropolitan area. All patients met DSM-IV criteria for major depressive disorder without psychosis, had a Hamilton Depression Rating Scale (HAMD17) score >18 and were between the ages of 18 and 65. The primary measure of efficacy was the change in HAMD 17 total score from baseline to endpoint. The data were collected between 1998 and 2004. There was a significant reduction in the HAMD17 scores from baseline to endpoint. Half the patients (n=6) showed > or =50% reduction in their HAMD17 scores. This study points to the potential of olanzapine as a therapeutic agent for the treatment of major depressive disorder without psychosis.

RESUMO

The likelihood, size, and speed of eyelid movements are thought to covary during the acquisition and expression of conditioning in rabbits (Oryctolagus cuniculus) and are generally accepted as interchangeable measures of the associative strength activated by the conditioned stimulus (CS). To test this assumption, the authors examined the patterns of covariation in these eyelid movement measures in acquisition and stimulus generalization in the upper eyelid and nictitating membrane. Rather than the expected covariation among these measures, eyelid movement magnitudes during the CS were distributed in approximately a bimodal manner. That is, eyelid activity consisted largely of a mixture of very small (< 0.125 mm) baseline measurements and larger (> 1 mm) movements. The results are discussed with respect to their implications for real-time models of eyelid conditioning.

RESUMO

IMPORTANCE: This research examines the impact of 4 weeks of repetitive transcranial magnetic stimulation (rTMS) stimulation to the temporoparietal junction and compares the results of this longer duration of treatment with a similar stimulus protocol of only 2 weeks' duration. OBJECTIVE: To examine the effectiveness and safety of 4 weeks of low-frequency rTMS to the left temporoparietal junction in a cohort of patients with bothersome tinnitus. DESIGN: Crossover, double-blind, randomized controlled trial. SETTING: Outpatient academic medical center. PARTICIPANTS: The study population comprised 14 adults aged between 22 and 59 years with subjective, unilateral or bilateral, nonpulsatile tinnitus of 6 months' duration or greater and a score of 34 or greater on the Tinnitus Handicap Inventory (THI). INTERVENTIONS: Low-frequency (1 Hz) 110% motor threshold rTMS or sham to the left temporoparietal junction for 4 weeks. MAIN OUTCOME AND MEASURE: The difference of the change in the THI score between active rTMS and sham rTMS. RESULTS: Active treatment was associated with a median reduction in THI score of 10 (range, -20 to +4) points, and sham treatment was associated with a median reduction of 6 (range, -24 to +12) points. The median difference in THI score between the change associated with active and sham rTMS was 4 (95% CI, -9 to 10; and range, -32 to +14) points. CONCLUSIONS AND RELEVANCE: Daily low-frequency active rTMS to the left temporoparietal junction area for 4 weeks was no more effective than sham for patients with chronic bothersome tinnitus. Possible explanations for this negative study include the failure of rTMS to stimulate deeper parts of auditory cortex within the sylvian fissure and more widespread cortical network changes not amenable to localized rTMS effects.

RESUMO

Neurocognitive tests compared abilities in people with bothersome tinnitus against an age-, gender-, and education-matched normative population. Participants between 18 and 60 years had subjective, unilateral or bilateral, nonpulsatile tinnitus for >6 months and a Tinnitus Handicap Inventory score of ≥ 38. Results from a first testing session showed deficits in learning, learning rates, immediate recall of heard words, and use of a serial order encoding strategy. Initial reliance on serial order encoding and, later, increased intrusion of incorrect words towards normal levels might indicate a less demanding strategy to compensate for weakness in associative memory for semantic categories.

RESUMO

OBJECTIVE: To examine the effectiveness and safety of low-frequency repetitive transcranial magnetic stimulation (rTMS) to the temporoparietal junction in a cohort of patients with bothersome tinnitus. DESIGN: Crossover, double-blind, randomized clinical trial. SETTING: Outpatient academic medical center. PARTICIPANTS: Fourteen adults aged 42 to 59 years with subjective, unilateral or bilateral, nonpulsatile tinnitus of 6 months' duration or longer and a score of 38 or greater on the Tinnitus Handicap Inventory (THI). INTERVENTIONS: Low-frequency (1-Hz) 110% motor threshold rTMS or sham treatment to the left temporoparietal junction for 2 weeks. MAIN OUTCOME MEASURE: The difference in the change of the THI score between active and sham rTMS. RESULTS: Active treatment was associated with a median (95% confidence interval) reduction in THI score of 5 (0-14) points, and sham treatment was associated with a median reduction in THI score of 6 (-2 to 12) points. The difference in THI scores between the change associated with active and sham rTMS ranged from a 34-point reduction in THI score after active treatment to a 22-point increase after sham treatment, with a median difference change of only 1 point (-6 to 4 points). CONCLUSIONS: Daily low-frequency rTMS to the left temporoparietal junction area for 2 weeks is no more effective than placebo for patients with chronic bothersome tinnitus. Possible explanations for the negative findings are short duration of treatment, failure of rTMS stimulation over the temporoparietal area to affect the auditory cortex buried within the Sylvian fissure, or more widespread cortical network changes associated with severe bothersome tinnitus not amenable to localized rTMS effects.

RESUMO

BACKGROUND: Postpartum depression (PPD) is a prevalent illness, affecting 10-15% of new mothers. PPD is the most common complication of childbirth and is a significant public health concern. It is known to adversely impact maternal-infant bonding, childrearing practices, and can lead to suicide and infanticide. The current treatment approaches to PPD are suboptimal. Many mothers are reluctant to take medication because of concerns about side effects or exposure of their newborn infant through breastfeeding. The specific aims of this study were to (1) examine acute treatment effectiveness, (2) examine response durability, and (3) assess an effect of repetitive transcranial magnetic stimulation (rTMS) on maternal bonding. METHODS: Nine antidepressant-free women with PPD were given 20 rTMS treatments over 4 weeks (10Hz, 120% motor threshold, left dorsolateral prefrontal cortex). Multiple characteristics were assessed at baseline and throughout treatment. Duration of effect was assessed at 30 days, 3 months and 6 months posttreatment. RESULTS: Friedman's tests were conducted on Hamilton Rating Scale for Depression-24 item (HRSD-24), Edinburgh Postnatal Depression Scale (EPDS), Inventory of Depressive Symptomatology-Self-Report (IDS-SR) and Clinical Global Impressions-Severity (CGI-S) scores to compare performances at four time points (baseline, end of Week 2, end of Week 4, and 180-day follow-up). Overall, these results revealed a significant reduction in depressive symptoms by the end of Week 2 of treatment. Analyses yielded a medium effect size (r=0.68) on the primary outcome variable (HRSD-24). Of note, all nine patients remained in treatment for the complete 4 weeks, did not miss any treatment sessions and eight participants achieved remission of symptoms, defined as a HRSD<10 and a CGI-S=1. Analysis of follow-up data indicated robustness of the rTMS treatment over time. At 6-month follow-up, of the eight women that remitted, seven remained in remission without further psychiatric intervention, including the addition of medication and one was lost to follow-up. Results also indicated a significant improvement in bonding. CONCLUSIONS: Our results demonstrate promising results for the use of rTMS in the treatment of PPD. Further randomized, sham-controlled studies need to be completed.

RESUMO

CONTEXT: Research on vascular depression has used 2 approaches to subtype late-life depression, based on executive dysfunction or white matter hyperintensity severity. OBJECTIVE: To evaluate the relationship of neuropsychological performance and white matter hyperintensity with clinical response in late-life depression. DESIGN: Two-site, prospective, nonrandomized controlled trial. SETTING: Outpatient clinics at Washington University and Duke University. PARTICIPANTS: A total of 217 subjects aged 60 years or older met DSM-IV criteria for major depression, scored 20 or more on the Montgomery-Asberg Depression Rating Scale (MADRS), and received vascular risk factor scores, neuropsychological testing, and magnetic resonance imaging; they were excluded for cognitive impairment or severe medical disorders. Fazekas rating was conducted to grade white matter hyperintensity lesions. Intervention Twelve weeks of sertraline treatment, titrated by clinical response. Main Outcome Measure Participants' MADRS scores over time. RESULTS: Baseline neuropsychological factor scores correlated negatively with baseline Fazekas scores. A mixed model examined effects of predictor variables on MADRS scores over time. Baseline episodic memory (P = .002), language (P = .007), working memory (P = .01), processing speed (P < .001), executive function factor scores (P = .002), and categorical Fazekas ratings (P = .05) predicted MADRS scores, controlling for age, education, age of onset, and race. Controlling for baseline MADRS scores, these factors remained significant predictors of decrease in MADRS scores, except for working memory and Fazekas ratings. Thirty-three percent of subjects achieved remission (MADRS < or =7). Remitters differed from nonremitters in baseline cognitive processing speed, executive function, language, episodic memory, and vascular risk factor scores. CONCLUSIONS: Comprehensive neuropsychological function and white matter hyperintensity severity predicted MADRS scores prospectively over a 12-week treatment course with selective serotonin reuptake inhibitors in late-life depression. Baseline neuropsychological function differentiated remitters from nonremitters and predicted time to remission in a proportional hazards model. Predictor variables correlated highly with vascular risk factor severity. These data support the vascular depression hypothesis and highlight the importance of linking subtypes based on neuropsychological function and white matter integrity.
