Seeing shapes and hearing textures: Two neural categories of touch

Touching for shape recognition has been shown to activate occipital areas in addition to somatosensory areas. In this study we asked if this combination of somatosensory and other sensory processing areas also exist in other kinds of touch recognition. In particular, does touch for texture roughness matching activate other sensory processing areas apart from somatosensory areas? We addressed this question with functional magnetic resonance imaging (fMRI) using wooden abstract stimulus objects whose shape or texture were to be identified. The participants judged if pairs of objects had the same shape or the same texture. We found that the activated brain areas for texture and shape matching have similar underlying structures, a combination of the primary motor area and somatosensory areas. Areas associated with object-shape processing were activated between stimuli during shape matching and not texture roughness matching, while auditory areas were activated during encoding of texture and not for shape stimuli. Matching of textures also involves left BA47, an area associated with retrieval of relational information. We suggest that texture roughness is recognized in a framework of ordering. Left-lateralized activations favoring texture might reflect semantic processing associated with grading roughness quantitatively, as opposed to the more qualitative distinctions between shapes.publishedVersio

Task-based functional connectivity reveals aberrance with the salience network during emotional interference in late-life depression

Objectives Late-life depression (LLD) is a common and debilitating disorder. Previously, resting-state studies have revealed abnormal functional connectivity (FC) of brain networks in LLD. Since LLD is associated with emotional-cognitive control deficits, the aim of this study was to compare FC of large-scale brain networks in older adults with and without a history of LLD during a cognitive control task with emotional stimuli. Methods Cross-sectional case-control study. Twenty participants diagnosed with LLD and 37 never-depressed adults 60–88 years of age underwent functional magnetic resonance imaging during an emotional Stroop task. Network-region-to-region FC was assessed with seed regions in the default mode, the frontoparietal, the dorsal attention, and the salience networks. Results FC between salience and sensorimotor network regions and between salience and dorsal attention network regions were reduced in LLD patients compared to controls during the processing of incongruent emotional stimuli. The normally positive FC between these networks were negative in LLD patients and inversely correlated with vascular risk and white matter hyperintensities. Conclusions Emotional-cognitive control in LLD is associated with aberrant functional coupling between salience and other networks. This expands on the network-based LLD model and proposes the salience network as a target for future interventions.publishedVersio

The effect of anxiety on cognition in older adult inpatients with depression: results from a multicenter observational study

Late-life depression is associated with reduced cognitive function beyond normal age-related cognitive deficits. As comorbid anxiety frequently occur in late-life depression, this study aimed to examine the association between anxiety symptoms and cognitive function among older inpatients treated for depression. We hypothesized that there would be an overall additive effect of comorbid anxiety symptoms on dysfunction across cognitive domains. The study included 142 patients treated for late-life depression in hospital, enrolled in the Prognosis of Depression in the Elderly study. Anxiety symptoms were measured at admission using the anxiety subscale of the Hospital Anxiety and Depression Scale. Patients completed cognitive tasks at admission and discharge. Linear mixed and generalized linear mixed models were estimated to investigate the effect of anxiety, on continuous and categorical cognitive scores, respectively, while controlling for depression. Anxiety severity at admission was not associated with performance in any of the cognitive domains. Patients with more symptoms of anxiety at admission demonstrated a significant improvement in immediate recall during the hospital stay. Patients with a score above cutoff indicating clinically significant symptoms on the anxiety subscale performed better on general cognitive function, as measured by the Mini Mental Status Examination at admission, than those below cutoff for anxiety. In conclusion, comorbid anxiety symptoms had no additive effect on cognitive dysfunction in late-life depression in our sample of inpatients.The effect of anxiety on cognition in older adult inpatients with depression: results from a multicenter observational studyThe study reported in this article was supported by the Old Age Psychiatry Research Group, Oslo University Hospital, Norway.

Sammenhengen mellom depresjon, mental helse og fysisk funksjon i en alderspsykiatrisk avdeling, en pilotstudie

Patients with mental disorders are often less active than the general population and inactivity over time reduces mental and physical health. We know from previous studies that physical activity contributes to improved mental and physical health, but it is not clear whether any type of physical activity will give the same effect. The objective of this pilot study was to investigate whether the nature of the physical activity the patients participated in during their stay in a psychiatric ward would make a difference in outcome related to improved mental and physical health. Fifty patients (39 women) participated, mean age 80 years (SD 6.0), length of stat from 3 to 28 weeks (mean 8.8, SD 4.4). Patients were offered different types of physical activity and physical therapy in addition to cognitive psychotherapy and supporting conversations. They were subsequently divided into three groups (self-training, joint exercise, regular walking). We examined the difference in treatment effect with regard to general mental health, depression, balance, physical strength and walking skills. Average values showed significant improvements on all tests except for the timed walking tests. Depression scores according to the MADRS was at least one category lower on discharge than on arrival for 31 of the 36 participants. We find that older patients with moderate to severe depression benefit greatly from the treatment they receive during their stay at the age psychiatric ward. The improvements are significant both for mental and physical health. Furthermore, the findings indicate that walking appears to be a type of activity that has especially good effect on mental health

Managing depressive symptoms in people with mild cognitive impairment and mild dementia with a multicomponent psychotherapy intervention: A randomized controlled trial

Objective: To evaluate the feasibility and effectiveness of the CORDIAL program, a psychosocial intervention consisting of cognitive behavioral therapy (CBT), cognitive rehabilitation, and reminiscence to manage depressive symptoms for people with mild cognitive impairment (MCI) or dementia. Design: We conducted a randomized controlled trial, based on a two-group (intervention and control), pre-/post-intervention design. Setting: Participants were recruited from five different old age psychiatry and memory clinics at outpatients’ hospitals. Participants: Hundred and ninety-eight people with MCI or early-stage dementia were included. Intervention: The intervention group (n = 100) received 11 individual weekly sessions of the CORDIAL program. This intervention includes elements from CBT, cognitive rehabilitation, and reminiscence therapy. The control group (n = 98) received treatment-as-usual. Measurements: We assessed Montgomery–Åsberg Depression Rating Scale (MADRS) (main outcome), Neuropsychiatric Inventory Questionnaire, and Quality of Life in Alzheimer’s disease (secondary outcomes) over the course of 4 months and at a 10-month follow-up visit. Results: A linear mixed model demonstrated that the depressive symptoms assessed by MADRS were significantly more reduced in the intervention groups as compared to the control group (p < 0.001). The effect persisted for 6 months after the intervention. No significant differences between groups were found in neuropsychiatric symptoms or quality of life. Conclusion: Our multicomponent intervention, which comprised 11 individual sessions of CBT, cognitive rehabilitation, and reminiscence therapy, reduced depressive symptoms in people with MCI and dementia

COVID-19 concerns among old age Psychiatric In- and out-patients and the employees caring for them, a preliminary study

A questionnaire was administered to 14 patients admitted at the Department of Old Age Psychiatric 24-h unit at Oslo University Hospital with questions about experiences and fears regarding COVID-19. A similar adjusted questionnaire was administered to 19 outpatients. The purpose was to investigate if the patients had fears, anxieties, and quality of life issues related to COVID-19 that could affect their treatment. A quest back questionnaire with similar questions about patient care and work conditions was sent to the personnel working with these patients, and 46 of 81 responded. Most patients welcomed the strict measures that were applied, including a visitation ban for inpatients and a reduction in consultations for the outpatients. Most patients reported that they were not very scared of getting COVID-19, nor did many believe that they would die if they were infected. A minority of patients reported being very worried. The patients also differed on other issues related to the COVID-19 situation. A minority were negative to the interventions, rules, and regulations, and/or considered the risk of infection to be elevated at the clinic, and/or that the quality of their daily life was negatively impacted. Employees more often than patients were concerned about the COVID-19 influence on their health. They were also concerned about being at work amid the crisis. About half of their comments were related to the fear of inadvertently infecting patients with COVID-19. Also, a majority complained about aspects related to the implemented COVID-19 guidelines. This study is explorative in nature, mainly due to its small sample size, which makes it difficult to draw conclusions from the results. However, the results imply a need for addressing the COVID-19 concerns of both patients and employees, to prevent potential negative effects on treatment and overall life quality. Future research should investigate the self-reported effects of the pandemic situation on a larger sample size of elderly psychiatric patients

Brain Morphometric Correlates of Depressive Symptoms among Patients with and without Dementia

Introduction: Findings regarding brain morphometry among patients with dementia and concomitant depressive symptoms have been inconsistent. Thus, the aim of the present study was to test the hypothesis that dementia and concomitant depressive symptoms are associated with structural brain changes in the temporal lobe measured with structural magnetic resonance imaging (MRI). Methods: A sample of 492 patients from Norwegian memory clinics (n = 363) and Old Age Psychiatry services (n = 129) was studied. The assessment included the Cornell Scale for Depression in Dementia (CSDD), Instrumental Activities of Daily Living Scale, Mini Mental State Examination, and MRI of the brain, processed with FreeSurfer to derive ROI measures of cortical thickness, volume, and area using the Desikan-Killiany parcellation, as well as subcortical volumes. Dementia was diagnosed according to ICD-10 research criteria. Correlates of brain morphometry using multiple linear regression were examined. Results: Higher scores on the CSDD were associated with larger cortical volume (β = 0.125; p value = 0.003) and area of the left isthmus of the cingulate gyrus (β = 0.151; p value = &#x3c;0.001) across all patients. Inclusion of an interaction term (dementia × CSDD) revealed a smaller area in the left temporal pole (β = −0.345; p value = 0.001) and right-transverse temporal cortex (β = −0.321; p value = 0.001) in patients with dementia and depressive symptoms. Discussion/Conclusion: We confirm the previous findings of structural brain changes in temporal regions among patients with dementia and concomitant depressive symptoms. This may contribute to a better understanding of the mechanisms underlying depression in dementia. To the best of our knowledge, this is the largest study conducted on this topic to date
