Psychotherapy of attention deficit hyperactivity disorder in adults--a pilot study using a structured skills training program.

Abstract In clinical practice many adult patients with attention deficit hyperactivity disorder (ADHD) ask for an additional psychotherapeutic intervention besides the medical therapy. In this paper we present a structured skill training program particularly tailored for adult patients with ADHD. The program is based on the principles of cognitive-behavioral treatment for borderline personality disorder developed by M. Linehan. It was modified to suit the special needs of adult patients with ADHD. In this exploratory pilot study we tested this program in a group setting. The following elements were presented: neurobiology of ADHD, mindfulness, chaos and control, behavior analysis, emotion regulation, depression, medication in ADHD, impulse control, stress management, dependency, ADHD in relationship and self respect.In an open study design patients were assessed clinically using psychometric scales (Attention Deficit Hyperactivity Disorder Checklist according to DSM-IV, 16 items of the SCL-90-R, Beck-Depression Inventory, visual analogue scale) prior to and following group therapy. This treatment resulted in positive outcomes in that patients improved on all psychometric scales.

Cognitive behavioral analysis system of psychotherapy versus interpersonal psychotherapy for early-onset chronic depression: A randomized pilot study

BACKGROUND The only psychotherapy specifically designed and evaluated for the treatment of chronic depression, the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), has never been directly compared to another depression-specific psychological method. METHODS Thirty patients with early-onset chronic depression were randomized to 22 sessions of CBASP or Interpersonal Psychotherapy (IPT) provided in 16 weeks. Primary outcome was the score on the 24-item Hamilton Rating Scale for Depression (HRSD) assessed posttreatment by an independent blinded evaluator. Secondary endpoints were, among others, remission (HRSD≤8) rates and the Beck Depression Inventory (BDI). The study included a prospective naturalistic 12-month follow-up. RESULTS Intent-to-treat analyses of covariance (ANCOVA) revealed that there was no significant difference in posttreatment HRSD scores between the CBASP and the IPT condition, but in self-rated BDI scores. We found significantly higher remission rates in the CBASP (57%) as compared to the IPT (20%) group. One year posttreatment, no significant differences were found in the self-reported symptom level (BDI) using ANCOVA. LIMITATIONS The study used only a small sample size and no placebo control. The generalizability of the results may be limited to patients with a preference for psychological treatment. CONCLUSIONS While the primary outcome was not significant, secondary measures showed relevant benefits of CBASP over IPT. We found preliminary evidence that in early-onset chronic depression, an approach specifically designed for this patient population was superior to a method originally developed for the treatment of acute depressive episodes. Long-term results suggest that chronically depressed patients may need extended treatment courses.

Mapping of temporal and parietal cortex in progressive nonfluent aphasia and Alzheimer's disease using chemical shift imaging, voxel-based morphometry and positron emission tomography

Little and controversial evidence is available from neuroimaging studies in progressive nonfluent aphasia (PNA). The goal of this study was to combine information from different imaging modalities in PNA compared with Alzheimers disease (AD). Chemical shift imaging (CSI), voxel-based morphometry (VBM) and fluorodeoxyglucose positron emission tomography (FDG-PET) were used in 5 PNA, 10 AD patients and 10 normal subjects. Group comparisons revealed left anterior lateral temporal abnormalities (BA20/21) in PNA using CSI, VBM and PET in comparison to normal subjects. AD patients showed more limited hypometabolism within the same area. In addition left lateral parietal (BA40) abnormalities were demonstrated in our PNA as well as our AD group using PET and VBM (AD group only). Combining information from all imaging modalities on a single case basis revealed pathology within the left anterior lateral temporal and lateral parietal lobe both in PNA and AD. PNA and AD patients differed significantly, however, with respect to the frequency of medial temporal lobe and posterior cingulate/precuneus involvement. Although our results might not be generalizable to all subgroups of PNA, we conclude that medial temporal and posterior cingulate/precuneus cortex pathology as assessed by CSI and VBM or PET distinguish PNA from AD, whereas lateral temporal and parietal areas are involved in both conditions.

Hemispheric asymmetries of hypometabolism associated with semantic memory impairment in Alzheimer's disease: a study using positron emission tomography with fluorodeoxyglucose-F18

Considerable disagreement exists about the neuroanatomical basis of conceptual-semantic impairments observed in a subgroup of patients with Alzheimers disease (AD) at mild to moderate stages of the disease. Several studies of groups of patients have shown correlations between focal hypometabolism or hypoperfusion in left hemispheric areas and measures of verbal semantic memory impairment in AD patients. The question remains, however, whether left hemispheric hypometabolism is sufficient to produce such impairment in the single case and whether nonverbal semantic knowledge is also affected. We used positron emission tomography (PET) with fluorodeoxyglucose-F18 (FDG), statistical parametric mapping (SPM), and tests of verbal and nonverbal semantic memory in 11 AD patients with a mean score on the Mini-Mental State Examination of 22.6 (+/-2.8). Naming impairment was significantly associated with left hemispheric asymmetry of hypometabolism on a single-case basis. Our correlation analysis showed that metabolism in left anterior temporal, posterior inferior temporal, inferior parietal and medial occipital areas (Brodmann areas: 21/38, 37, 40 and 19) correlated with both verbal and nonverbal semantic performance. We conclude that left hemispheric synaptic dysfunction, as measured by regional glucose hypometabolism, was sufficient to produce semantic impairments in our patients. The majority of areas affected in our patients with semantic impairments were involved in multimodal or supramodal (verbal and nonverbal) semantic knowledge.

Sensitivity to detect change and the correlation of clinical factors with the Hamilton Depression Rating Scale and the Beck Depression Inventory in depressed inpatients

Discrepancies between scores on the Hamilton Depression Rating Scale (HAMD) and the Beck Depression Inventory (BDI), as well as differences regarding their sensitivity to detect change, have been reported. This study investigates discrepancies and their potential prediction on the basis of demographic, personality, and clinical factors in depressed inpatients and analyzes the sensitivity to change. The HAMD and the BDI were administered to 105 inpatients with major depressive disorder randomized to 5 weeks of either interpersonal psychotherapy or clinical management. Personality was assessed with the NEO Five-Factor Inventory. Low extraversion and high neuroticism were associated with relatively higher endorsement of depressive symptoms on the BDI compared with the HAMD. The HAMD presented a greater reduction of symptom scores than the BDI. Patients with high BDI scores, high HAMD scores or both revealed the greatest change, possibly due to a statistical effect of regression to the mean. Restricted by sample size, analyses were not differentiated by treatment condition. Regression to the mean cannot be tested directly, but it might be considered as a possible explanation. The HAMD and the BDI should be regarded as two complementary rather than redundant or competing instruments as the discrepancy is associated with personality characteristics. Attributing large effect sizes solely to effective treatment and a sensitive measure may be misleading.

Early-onset Alzheimer's disease due to mutations of the presenilin-1 gene on chromosome 14: a 7-year follow-up of a patient with a mutation at codon 139.

Abstract Mutations in the presenilin-1 gene (PS-1 gene) on chromosome 14 have recently been identified as a cause of familial early-onset Alzheimer’s disease (EOAD). To our knowledge, only two German EOAD patients with mutations in the PS-1 gene have been identified thus far. Herein we report the case of a German EOAD patient with a family history of dementia and a missense mutation at codon 139 (M139V) of the PS-1 gene. The patient came to our clinic for the first time when he was 44 years old. During the following 7 years, his Mini-Mental State Examination (MMSE) score dropped from 24 to 0. Myocloni were an early neurological symptom that was already present during the first consultation. We could demonstrate that myoclonic activity was of cortical origin using a back-averaging method. Magnetic resonance imaging (MRI) revealed only slight changes in the early stage of the disease. Follow-up MRI studies showed progression of bitemporal ventricular enlargement and progressive frontal and temporal cortical atrophy. Although the majority of EOAD patients belong to the sporadic (non-genetic) type of AD, early-onset dementia, early myocloni and a familial history of AD should direct attention to the possibility of a genetic form of AD.

Patterns of Regional Brain Hypometabolism Associated with Knowledge of Semantic Features and Categories in Alzheimer's Disease

The study of semantic memory in patients with Alzheimers disease (AD) has raised important questions about the representation of conceptual knowledge in the human brain. It is still unknown whether semantic memory impairments are caused by localized damage to specialized regions or by diffuse damage to distributed representations within nonspecialized brain areas. To our knowledge, there have been no direct correlations of neuroimaging of in vivo brain function in AD with performance on tasks differentially addressing visual and functional knowledge of living and nonliving concepts. We used a semantic verification task and resting 18-fluorodeoxyglucose positron emission tomography in a group of mild to moderate AD patients to investigate this issue. The four task conditions required semantic knowledge of (1) visual, (2) functional properties of living objects, and (3) visual or (4) functional properties of nonliving objects. Visual property verification of living objects was significantly correlated with left posterior fusiform gyrus metabolism (Brodmanns area [BA] 37/19). Effects of visual and functional property verification for non-living objects largely overlapped in the left anterior temporal (BA 38/20) and bilateral premotor areas (BA 6), with the visual condition extending more into left lateral precentral areas. There were no associations with functional property verification for living concepts. Our results provide strong support for anatomically separable representations of living and nonliving concepts, as well as visual feature knowledge of living objects, and against distributed accounts of semantic memory that view visual and functional features of living and nonliving objects as distributed across a common set of brain areas.

Allgemeine Wirkfaktoren bei der Behandlung chronisch depressiver Patienten – Vergleich zweier Psychotherapieansätze

Hintergrund: Das Ausmaß, in dem allgemeine Wirkfaktoren die Wirksamkeit von Psychotherapie bei chronischer Depression beeinflussen, ist bisher wenig untersucht: Welche allgemeinen Wirkfaktoren unterscheiden erfolgreiche und weniger erfolgreiche Psychotherapien bei chronisch depressiven Patienten? Patienten und Methoden: Mit Hilfe des Berner Patienten- und Therapeutenstundenbogens (TSTB/PSTB) wurden bei 29 chronisch depressiven Patienten während einer 16-wöchigen Behandlung mit dem Cognitive Behavioral Analysis System of Psychotherapy (CBASP) oder der Interpersonellen Psychotherapie (IPT) wöchentlich die Wirkfaktoren erhoben und mittels Varianzanalyse verglichen. Als primäres Erfolgsmaß diente die 24-Item Hamilton Depressionsskala (HRSD-24). Ergebnisse: Aus Patientensicht zeigten sich signifikante Unterschiede zwischen erfolgreichen (Response-Kriterium definiert als mindestens 50%-Verbesserung im HRSD-24) und weniger erfolgreichen Therapien im Ausmaß «Motivationaler Klärung» (p = 0,02) und «Problembewältigung» (p = 0,01). Es konnten keine bedeutsamen Unterschiede bezüglich allgemeiner Wirkfaktoren von CBASP- versus IPT-Therapien nachgewiesen werden. Diskussion: Unabhängig von der spezifischen Therapiemethode bestätigt sich aus Patientensicht die Bedeutung intensiver Motivationaler Klärung sowie bewältigender Strategien für eine erfolgreiche Behandlung chronischer Depressionen.

Konzeption und Erprobung eines gruppentherapeutischen Behandlungskonzepts für die funktionelle Gedächtnis- und Konzentrationsstörung

OBJECTIVES Functional Memory and Attention Disorder (FMD) is regularly seen in patients presenting in psychosomatic or memory clinics. The aim of this study was the evaluation of a novel group therapy for FMD in a randomized controlled trial. METHODS 40 FMD patients were randomly assigned to either the experimental (EG) or the wait-list control group (CG). Out of these 35/31 were analysed (intent to treat vs. observed cases respectively). The intervention consisted of psychoeducation, cognitive restructuring, stress management, relaxation and mindfulness techniques. Data were collected at baseline, three months (post-intervention) and six months (follow-up). Primary outcome was the memory self-efficacy measure of the Metamemory in Adulthood Questionnaire (MSE). Secondary outcomes were the sum scores of the Perceived Stress Questionnaire (PSQ) and the SCL-90-R. RESULTS The EG showed a significantly higher improvement on MSE at follow-up than the CG. No significant group differences emerged on PSQ or SCL-90-R. The CG showed stable MSE scores during the waiting period without intervention. However, after the CG received their therapy the same pattern on MSE scores as seen in the EG emerged. CONCLUSIONS This study provides preliminary evidence for an improvement of memory self efficacy in FMD through a newly devised group therapy program consisting of different modules. This result ought to be replicated in larger studies.
