Music and Visual Art Training Modulate Brain Activity in Older Adults

Visual art- and music-based interventions as adjuvants in the treatment of eating disorders: a systematic review and a theoretical model

AIM

To assess the effect of visual art- and music-based interventions in the treatment of eating disorders.

METHODS

This study was registered in PROSPERO (CRD42020161503). Six databases (CINAHL, EMBASE, Lilacs, PsycINFO, PubMed and The Cochrane Library) were consulted. The searches were performed on 19 June 2019, and updated on 18 March 2022. No restriction on language, date, or publication status was applied. Methodological quality was assessed using Joanna Briggs Institute's instruments. All steps were performed by two independent reviewers and a third participated in the event of disagreement.

RESULTS

Eight studies were included. Few statistically significant results were found. Overall, both interventions might help to reduce negative emotional states.

CONCLUSION

Visual art- and music-based interventions present limited and inconclusive scientific evidence in patients with eating disorders and therefore their effectiveness is currently unknown. A theoretical model is proposed to guide future research. Further studies are needed to clarify their clinical relevance.

The effects of musical instrument training on fluid intelligence and executive functions in healthy older adults: A systematic review and meta-analysis

Intervention studiescombiningcognitive and motor demands have reported far-transfer cognitive benefits in healthy ageing. This systematic review and meta-analysis evaluated the effects of music and rhythm intervention on cognition in older adulthood. Inclusion criteria specified: 1) musical instrument training; 2) healthy, musically-naïve adults (≥60 years); 3) control group; 4) measure of executive function. Ovid, PubMed, Scopus and the Cochrane Library online databases were searched in August 2023. Data from thirteen studies were analysed (N = 502 participants). Study quality was assessed using the Cochrane Risk of Bias tool (RoB 2; Sterne et al., 2019). Random effects models revealed: a low effect on inhibition (d = 0.27,p = .0335); a low-moderate effect on switching (d = -0.39, p = .0021); a low-moderate effect on verbal category switching (d =0.39,p = .0166); and a moderate effect on processing speed (d = 0.47,p < .0001). No effect was found for selective visual attention, working memory, or verbal memory. With regards to overall bias, three studies were rated as "high", nine studies were rated as having "some concerns" and one was rated "low". The meta-analysis suggests that learning to play a musical instrument enhances attention inhibition, switching and processing speed in ageing.

Benefits of Cultural Activities on People with Cognitive Impairment: A Meta-Analysis

BACKGROUND

Museums and cultural institutions are increasingly aware of both the interests and needs of society. Accordingly, these institutions are becoming allies in terms of health and well-being due to the importance of their social functions. Presently, many institutions create cultural activities aimed at cognitively impaired people, a group on the rise owing to the prevalence of dementia and the aging of society. Nevertheless, scientific evidence in this field remains scarce. As a result, the main objective of this research was to empirically evaluate and identify the benefits that cultural interventions can bring to cognitively impaired participants.

METHOD

A meta-analysis (MA) was performed following PRISMA guidelines. When inclusion and eligibility criteria had been established, articles were subsequently selected through a strategic search of Web of Science, SCOPUS, PubMed, and Medline.

RESULTS

Twenty-six studies met the eligibility criteria, involving a total of 1201 participants with cognitive impairment. The results showed a statistically non-significant effect size when analyzing these cultural interventions for cognitively impaired people overall. However, when conducting partial meta-analyses (MA'), focusing on studies related to a specific disease, a particular type of treatment, or a specific type of evaluation, the results concurred with the conclusion of the previous systematic review (SR).

CONCLUSION

Despite the high heterogeneity of the studies, benefits were identified in emotional well-being and social aspects but not in clinical ones such as the deterioration of cognitive or motor function, among others.

Association of Arts Event Attendance With Cognitive Function Among Older Adults Enrolled in the Health and Retirement Study

Background and Objectives

Among the cognitively impaired, arts engagement is associated with improved neurocognitive symptoms. Less is known about arts engagement as a potentially modifiable lifestyle factor to prevent or slow cognitive decline. Our aim was to evaluate the association between arts event attendance and cognition.

Research Design and Methods

We used data from the 2014 and 2016 waves of the Health and Retirement Study to evaluate the association between arts event attendance and cognition using multivariable linear regressions. Arts event attendance in 2014 was our exposure of interest and included visiting an art museum or art gallery; attending an arts or crafts fair; attending a live performance (concert, play, or reading); and/or going to a movie theater. Cognitive function in 2016 measured on a 27-point scale by the Telephone Interview for Cognitive Status was our main outcome of interest.

Results

Of the 1,149 participants included in the final analysis, 70.7% attended an arts event. The mean baseline cognitive score was higher among those who attended art events (16.8 [standard deviation {SD}, ±3.8] vs 13.8 [SD, ±5.0]; p < .001). In our multivariable regressions, those who attended arts events in 2014 exhibited higher cognitive scores in 2016 after controlling for demographic, socioeconomic, health, and baseline cognitive covariates (β, 1.07 [95% confidence interval {CI}, 0.50-1.64]; p < .001). This association was primarily observed in those with lower baseline cognitive function (β, 1.19 [95% CI, 0.33-2.06]; p = .008).

Discussion and Implications

Arts event attendance may be associated with better cognitive function. Given concerns for residual confounding and reverse causality, this association warrants further study.

Quality standards and recommendations for research in music and neuroplasticity

Research on how music influences brain plasticity has gained momentum in recent years. Considering, however, the nonuniform methodological standards implemented, the findings end up being nonreplicable and less generalizable. To address the need for a standardized baseline of research quality, we gathered all the studies in the music and neuroplasticity field in 2019 and appraised their methodological rigor systematically and critically. The aim was to provide a preliminary and, at the minimum, acceptable quality threshold-and, ipso facto, suggested recommendations-whereupon further discussion and development may take place. Quality appraisal was performed on 89 articles by three independent raters, following a standardized scoring system. The raters' scoring was cross-referenced following an inter-rater reliability measure, and further studied by performing multiple ratings comparisons and matrix analyses. The results for methodological quality were at a quite good level (quantitative articles: mean = 0.737, SD = 0.084; qualitative articles: mean = 0.677, SD = 0.144), following a moderate but statistically significant level of agreement between the raters (W = 0.44, χ² = 117.249, p = 0.020). We conclude that the standards for implementation and reporting are of high quality; however, certain improvements are needed to reach the stringent levels presumed for such an influential interdisciplinary scientific field.

Auditory cognitive aging in amateur singers and non-singers

The notion that lifestyle factors, such as music-making activities, can affect cognitive functioning and reduce cognitive decline in aging is often referred to as the mental exercise hypothesis. One ubiquitous musical activity is choir singing. Like other musical activities, singing is hypothesized to impact cognitive and especially executive functions. Despite the commonness of choir singing, little is known about the extent to which singing can affect cognition in adulthood. In this cross-sectional group study, we examined the relationship between age and four auditory executive functions to test hypotheses about the relationship between the level of mental activity and cognitive functioning. We also examined pitch discrimination capabilities. A non-probabilistic sample of 147 cognitively healthy adults was recruited, which included 75 non-singers (mean age 52.5 ± 20.3; 20-98 years) and 72 singers (mean age 55.5 ± 19.2; 21-87 years). Tests of selective attention, processing speed, inhibitory control, and working memory were administered to all participants. Our main hypothesis was that executive functions and age would be negatively correlated, and that this relationship would be stronger in non-singers than singers, consistent with the differential preservation hypothesis. The alternative hypothesis - preserved differentiation - predicts that the difference between singers and non-singers in executive functions is unaffected by age. Our results reveal a detrimental effect of age on processing speed, selective attention, inhibitory control and working memory. The effect of singing was comparatively more limited, being positively associated only with frequency discrimination, processing speed, and, to some extent, inhibitory control. Evidence of differential preservation was limited to processing speed. We also found a circumscribed positive impact of age of onset and a negative impact of singing experience on cognitive functioning in singers. Together, these findings were interpreted as reflecting an age-related decline in executive function in cognitively healthy adults, with specific and limited positive impacts of singing, consistent with the preserved differentiation hypothesis, but not with the differential preservation hypothesis.

Music training modulates theta brain oscillations associated with response suppression

There is growing interest in developing training programs to mitigate cognitive decline associated with normal aging. Here, we assessed the effect of 3-month music and visual art training programs on the oscillatory brain activity of older adults using a partially randomized intervention design. High-density electroencephalography (EEG) was measured during the pre- and post-training sessions while participants completed a visual GoNoGo task. Time-frequency representations were calculated in regions of interest encompassing the visual, parietal, and prefrontal cortices. Before training, NoGo trials generated greater theta power than Go trials from 300 to 500 ms post-stimulus in mid-central and frontal brain areas. Theta power indexing response suppression was significantly reduced after music training. There was no significant difference between pre- and post-test for the visual art or the control group. The effect of music training on theta power indexing response suppression was associated with reduced functional connectivity between prefrontal, visual, and auditory regions. These results suggest that theta power indexes executive control mechanisms in older adults. Music training affects theta power and functional connectivity associated with response suppression. These findings contribute to a better understanding of inhibitory control ability in older adults and the neuroplastic effects of music interventions.

Music and Visual Art Training Increase Auditory-Evoked Theta Oscillations in Older Adults

Music training was shown to induce changes in auditory processing in older adults. However, most findings stem from correlational studies and fewer examine long-term sustainable benefits. Moreover, research shows small and variable changes in auditory event-related potential (ERP) amplitudes and/or latencies in older adults. Conventional time domain analysis methods, however, are susceptible to latency jitter in evoked responses and may miss important information of brain processing. Here, we used time-frequency analyses to examine training-related changes in auditory-evoked oscillatory activity in healthy older adults (N = 50) assigned to a music training (n = 16), visual art training (n = 17), or a no-treatment control (n = 17) group. All three groups were presented with oddball auditory paradigms with synthesized piano tones or vowels during the acquisition of high-density EEG. Neurophysiological measures were collected at three-time points: pre-training, post-training, and at a three-month follow-up. Training programs were administered for 12-weeks. Increased theta power was found pre and post- training for the music (p = 0.010) and visual art group (p = 0.010) as compared to controls (p = 0.776) and maintained at the three-month follow-up. Results showed training-related plasticity on auditory processing in aging adults. Neuroplastic changes were maintained three months post-training, suggesting music and visual art programs yield lasting benefits that might facilitate encoding, retention, and memory retrieval.

Does music training enhance auditory and linguistic processing? A systematic review and meta-analysis of behavioral and brain evidence

It is often claimed that music training improves auditory and linguistic skills. Results of individual studies are mixed, however, and most evidence is correlational, precluding inferences of causation. Here, we evaluated data from 62 longitudinal studies that examined whether music training programs affect behavioral and brain measures of auditory and linguistic processing (N = 3928). For the behavioral data, a multivariate meta-analysis revealed a small positive effect of music training on both auditory and linguistic measures, regardless of the type of assignment (random vs. non-random), training (instrumental vs. non-instrumental), and control group (active vs. passive). The trim-and-fill method provided suggestive evidence of publication bias, but meta-regression methods (PET-PEESE) did not. For the brain data, a narrative synthesis also documented benefits of music training, namely for measures of auditory processing and for measures of speech and prosody processing. Thus, the available literature provides evidence that music training produces small neurobehavioral enhancements in auditory and linguistic processing, although future studies are needed to confirm that such enhancements are not due to publication bias.

Transcranial Direct Current Stimulation Combined With Listening to Preferred Music Alters Cortical Speech Processing in Older Adults

Emerging evidence suggests transcranial direct current stimulation (tDCS) can improve cognitive performance in older adults. Similarly, music listening may improve arousal and stimulate subsequent performance on memory-related tasks. We examined the synergistic effects of tDCS paired with music listening on auditory neurobehavioral measures to investigate causal evidence of short-term plasticity in speech processing among older adults. In a randomized sham-controlled crossover study, we measured how combined anodal tDCS over dorsolateral prefrontal cortex (DLPFC) paired with listening to autobiographically salient music alters neural speech processing in older adults compared to either music listening (sham stimulation) or tDCS alone. EEG assays included both frequency-following responses (FFRs) and auditory event-related potentials (ERPs) to trace neuromodulation-related changes at brainstem and cortical levels. Relative to music without tDCS (sham), we found tDCS alone (without music) modulates the early cortical neural encoding of speech in the time frame of ∼100-150 ms. Whereas tDCS by itself appeared to largely produce suppressive effects (i.e., reducing ERP amplitude), concurrent music with tDCS restored responses to those of the music+sham levels. However, the interpretation of this effect is somewhat ambiguous as this neural modulation could be attributable to a true effect of tDCS or presence/absence music. Still, the combined benefit of tDCS+music (above tDCS alone) was correlated with listeners' education level suggesting the benefit of neurostimulation paired with music might depend on listener demographics. tDCS changes in speech-FFRs were not observed with DLPFC stimulation. Improvements in working memory pre to post session were also associated with better speech-in-noise listening skills. Our findings provide new causal evidence that combined tDCS+music relative to tDCS-alone (i) modulates the early (100-150 ms) cortical encoding of speech and (ii) improves working memory, a cognitive skill which may indirectly bolster noise-degraded speech perception in older listeners.

Benefits of choir singing on complex auditory encoding in the aging brain: An ERP study

Aging is accompanied by difficulties in auditory information processing, especially in more complex sound environments. Choir singing requires efficient processing of multiple sound features and could, therefore, mitigate the detrimental effects of aging on complex auditory encoding. We recorded auditory event-related potentials during passive listening of sounds in healthy older adult (≥ 60 years) choir singers and nonsinger controls. We conducted a complex oddball condition involving encoding of abstract regularities in combinations of pitch and location features, as well as in two simple oddball conditions, in which only either the pitch or spatial location of the sounds was varied. We analyzed change-related mismatch negativity (MMN) and obligatory P1 and N1 responses in each condition. In the complex condition, the choir singers showed a larger MMN than the controls, which also correlated with better performance in a verbal fluency test. In the simple pitch and location conditions, the choir singers had smaller N1 responses compared to the control subjects, whereas the MMN responses did not differ between groups. These results suggest that regular choir singing is associated both with more enhanced encoding of complex auditory regularities and more effective adaptation to simple sound features.

Musicianship-Related Structural and Functional Cortical Features Are Preserved in Elderly Musicians

Background

Professional musicians are a model population for exploring basic auditory function, sensorimotor and multisensory integration, and training-induced neuroplasticity. The brain of musicians exhibits distinct structural and functional cortical features; however, little is known about how these features evolve during aging. This multiparametric study aimed to examine the functional and structural neural correlates of lifelong musical practice in elderly professional musicians.

Methods

Sixteen young musicians, 16 elderly musicians (age >70), and 15 elderly non-musicians participated in the study. We assessed gray matter metrics at the whole-brain and region of interest (ROI) levels using high-resolution magnetic resonance imaging (MRI) with the Freesurfer automatic segmentation and reconstruction pipeline. We used BrainVoyager semiautomated segmentation to explore individual auditory cortex morphotypes. Furthermore, we evaluated functional blood oxygenation level-dependent (BOLD) activations in auditory and non-auditory regions by functional MRI (fMRI) with an attentive tone-listening task. Finally, we performed discriminant function analyses based on structural and functional ROIs.

Results

A general reduction of gray matter metrics distinguished the elderly from the young subjects at the whole-brain level, corresponding to widespread natural brain atrophy. Age- and musicianship-dependent structural correlations revealed group-specific differences in several clusters including superior, middle, and inferior frontal as well as perirolandic areas. In addition, the elderly musicians exhibited increased gyrification of auditory cortex like the young musicians. During fMRI, the elderly non-musicians activated predominantly auditory regions, whereas the elderly musicians co-activated a much broader network of auditory association areas, primary and secondary motor areas, and prefrontal and parietal regions like, albeit weaker, the young musicians. Also, group-specific age- and musicianship-dependent functional correlations were observed in the frontal and parietal regions. Moreover, discriminant function analysis could separate groups with high accuracy based on a set of specific structural and functional, mainly temporal and occipital, ROIs.

Conclusion

In conclusion, despite naturally occurring senescence, the elderly musicians maintained musicianship-specific structural and functional cortical features. The identified structural and functional brain regions, discriminating elderly musicians from non-musicians, might be of relevance for the aging musicians’ brain. To what extent lifelong musical activity may have a neuroprotective impact needs to be addressed further in larger longitudinal studies.

Piano Training Enhances Executive Functions and Psychosocial Outcomes in Aging: Results of a Randomized Controlled Trial

Objectives

Preliminary evidence suggests piano training may enhance areas of executive functions and psychosocial outcomes in aging adults. However, little is known regarding specific cognitive outcomes affected and whether or not enhancements are sustainable. We conducted a randomized controlled trial to evaluate the effects of piano training on cognitive performance, psychosocial well-being, and physiological stress and immune-function, in older adults.

Methods

Older adults (N=155, 60-80 years) completed an initial three-hour assessment of standardized cognitive and psychosocial measures. Participants were randomly assigned to one of three groups: piano training, computer-assisted cognitive training, or a no treatment control group. Training groups completed a 16-week program with two group training sessions per week for 90 minutes each session. All participants completed a standard battery of executive functions (working memory, processing speed, verbal fluency), psychosocial measures (musical and general self-efficacy, mood), and physiological measures (cortisol and immune-function) at pretesting, posttesting, and at a three-month follow-up time point.

Results

Results showed that piano training and computer-assisted cognitive training enhanced working memory and processing speed as compared to controls. Piano training significantly increased verbal fluency skills in category switching, as compared to computer-assisted cognitive training and no treatment controls. Participants in piano training demonstrated enhanced general and musical self-efficacy post-training; however, no significant differences were found for physiological measures.

Discussion

Piano training resulted in a unique advantage in category switching as compared to computer-assisted cognitive training and no treatment controls. Music training programs may mitigate or prevent cognitive deficits in verbal skills.

Benefits of Cultural Activities on People With Cognitive Impairment: A Systematic Review

Museums and cultural institutions are increasingly striving to respond to the interests and needs of the society that hosts them. This means, apart from other actions, that these institutions must be involved in the health and wellbeing of society, and the creation of cultural activities aimed at people with cognitive impairment, a group of individuals that is growing worldwide due to the aging of society and the increasing prevalence of dementia. The involved sectors are aware of the potential and benefits of activities for this population, even though there is much research to be conducted. To date, no systematic review has focused on the benefits of cultural activities for cognitively impaired people. This study aimed to explore the benefits of different modalities of cultural activities with evidence from 145 studies from various databases, which met the inclusion criteria. Significant improvements in general cognition, quality of life (QoL), emotional wellbeing, socialization, and communication were generally reported after interventions, with a reduction in depression symptoms. There was not enough evidence to prove memory, language, or daily functioning improvements attributable to cultural interventions. There were no significant reductions reported in apathy, sadness, agitation, or anxiety.

Moderate-Intensity Physical Activity, Music and Art Activities Preserved Cognitive Health in Older Adults: An Argument for Social Prescribing Solution

Introduction: Rates of dementia are projected to increase over the coming years as global populations age. Without a treatment to slow the progression of dementia, many health policies are focusing on preventing dementia by slowing the rate of cognitive decline with age. However, it is unclear which lifestyle changes in old age meaningfully reduce the rate of cognitive decline associated with aging. Objectives: Use existing, multi-year longitudinal health data to determine if engagement in a variety of different lifestyle activities can slow the rate of cognitive decline as older adults age. Method: Data from the English Longitudinal Study of Aging was analyzed using a quasi-experimental, efficient matched-pair design inspired by the clinical trial methodology. Changes in short-term memory scores were assessed over a multi-year interval for groups who undertook one of 11 different lifestyle activities, compared to control groups matched across confounding socioeconomic and lifestyle factors. Results: Two factors, moderate-intensity physical activity and learning activities, resulted in significant positive impact on cognitive function. Conclusion: Our analysis brings cognitive benefit arguments in favor of two lifestyle activities, moderate-intensity physical activity and learning activities, while rejecting other factors advanced by the literature such as vigorous-intensity physical activity. Those findings justify and encourage the development of new lifestyle health programs by health authorities and bring forward the new health system solution, social prescribing.

Happiness: A Novel Outcome Measure in Stroke?

In this narrated review, we draw attention to the use of happiness as a novel outcome measure in clinical research studies regarding patients with stroke. Commonly used outcome measures in clinical trials in stroke rehabilitation include the modified Rankin Score (mRS), Functional Impairment Measures (FIM), Barthel Index and quality of life (QoL). Despite being a part of QoL, happiness is arguably a significant construct on its own. While QoL assesses perceptions of various extrinsic aspects of life, happiness may be used as a measure of subjective enjoyment of life after an illness. We review the literature discussing the use of happiness as a formal outcome measure in stroke care and subacute and long-term stroke rehabilitation. Ultimately we recommend the wider use of happiness as an outcome measure where appropriate in these settings.

Creative Art Therapy as a Non-Pharmacological Intervention for Dementia: A Systematic Review

Background

Non-pharmacological therapies have been shown to be effective in managing challenging behavior in people with dementia. However, the efficacy of art therapy has yet to be determined.

Objective

In the present systematic review, we evaluate the efficacy of art therapy as a non-pharmacological intervention for dementia and examine whether art therapy improves wellbeing and quality of life while decreasing biological and psychological symptoms of dementia (BPSD).

Methods

Research undertaken between 2015 and 2020 was examined and a total of seventeen studies met the specified search criteria, with 853 participants (657 people with dementia, 180 formal and informal carers, and 16 volunteers) involved.

Results

We identified four outcome domains: wellbeing, quality of life, BPSD, and cognitive function. One or more significant outcomes as having an impact on the efficacy of the intervention were reported in 88% (15/17) of the studies, whereas 17% (3/17) demonstrated significant outcomes across quality of life, wellbeing, and BPSD.

Conclusion

People with dementia benefit from art therapy. These interventions when incorporating elements of being 'in the moment' increase opportunities for communication between people with dementia and their caregiver(s) and facilitate person-centered therapeutic activities.

Personalized treatment interventions: nonpharmacological and natural treatment strategies in Alzheimer's disease

Introduction: Alzheimer's disease (AD) is a slow, irreversible, progressive, complex, and fatal neurodegenerative disorder. Available pharmacological treatment, known for almost two decades, does not cure the disease, but only alleviates the symptoms, with various efficacy and different side effects. Therefore, there is an unmet need to find other person-centered or personalized approaches to treat AD.Areas covered: This article describes the application of precision medicine-like approaches utilizing nonpharmacological treatment strategies and the use of natural products in personalized care for patients with AD.Expert opinion: Due to the heterogeneity of disease symptoms, somatic conditions, and patient preferences, there is definitely no "one size fits all" intervention. Therefore, individualized treatment choice is based on dementia stage, medical and psychiatric comorbidity, leading symptoms, patient preferences, and remaining capacity of the patient. In the absence of disease-modifying agents, a patient-centered, multidisciplinary team approach appears to be the best option to alleviate the heavy symptomatic burden in this unfortunate population. Hence, appropriate interventions can be offered along the AD continuum, while a better understanding of personal characteristics might help in establishing optimal individualized treatment, as well as its duration and intensity, to deliver interventions in the most effective ways.

Impaired face recognition is associated with abnormal gray matter volume in the posterior cingulate cortex in congenital amusia

Congenital amusia is as a neurodevelopment disorder primarily defined by impairment in pitch discrimination and pitch memory. Interestingly, it has been reported that individuals with congenital amusia also exhibit deficits in face recognition (prosopagnosia). One explanation of such comorbidity is that the neural substrates of pitch recognition and face recognition may be similar. To test this hypothesis, face recognition ability was assessed using the Cambridge Face Memory Test (CFMT) and gray matter volume was determined through voxel-based morphometry (VBM) among participants with and without congenital amusia. As expected, participants with amusia performed worse on the CFMT test and showed reduced gray matter volume (GMV) in the middle temporal gyrus (MTG), the superior temporal gyrus (STG), and the posterior cingulate cortex (PCC) in the right hemisphere, when compared with matched controls. Furthermore, correlation analyses demonstrated that the CFMT score was positively related to MTG, STG, and PCC GMV in all participants, while separate analyses of each group found a positive correlation of CFMT score and PCC GMV in amusics. These findings suggest that face recognition is associated with a widely distributed microstructural network in the human brain and the PCC plays an important role in both pitch recognition and face recognition in amusics. In addition, neurodevelopmental disorders such as congenital amusia and prosopagnosia may share a common neural substrate.

Can Visual Art Therapy Be Implemented With Illiterate Older Adults With Mild Cognitive Impairment? A Pilot Mixed-Method Randomized Controlled Trial

Older adults with mild cognitive impairment (MCI) with no literacy are at increased risk of progression to dementia. Whether it is feasible to engage this population in visual art therapy (VAT) and yield effects on cognition and depression remained unclear. A pilot mixed-method single-blinded randomized controlled trial was conducted in a sample of community-dwelling older adults with MCI. The experimental group (n = 21) was assigned to 12 sessions of VAT over 6 weeks, and the control group (n = 18) was assigned to 6 weekly health education (HE) on nonbrain health topics. Participants were evaluated at baseline using Montreal Cognitive Assessment-5-minute protocol (MoCA-5-min) and Geriatric Depression Scale Short Form (GDS-SF). A focus group discussion (FGD) was also conducted to the experimental group to explore their experiences of participating in the VAT. Findings indicated that both VAT and HE groups had significant improvement in MoCA-5-min scores and depressed mood over time; however, the significant group × time interaction effect was noted only for the psychological outcome. Findings from the FGD indicated that participants had challenging experiences at the beginning of the therapy, but later, they were able to cope and found that the VAT was relevant and beneficial for their cognitive and psychosocial health. This pilot study provided initial evidence about the potential benefit of VAT in improving cognitive and psychological well-being of older adults with MCI and low literacy and provided insights on how to better engage them in this cognitive stimulating intervention. A full-scale trial is recommended for a stringent evaluation.

Experticia y cognición. Exploración de funciones cognitivas verbales y visoespaciales en arquitectos y psicólogos

Diversas investigaciones han advertido que el ejercicio de algunas profesiones puede conllevar efectos moduladores en la estructura cerebral y el funcionamiento cognitivo. Se presentan los resultados de un estudio exploratorio transversal referente a las modificaciones que las experticias en arquitectura (N = 41, edad: X = 39, DE = 10) y en psicología (N = 40, edad: X = 35, DE = 7) producen sobre procesos cognitivos específicos. El objetivo general fue contribuir a la determinación de perfiles cognitivos diferenciales. Los arquitectos mostraron un mejor rendimiento en tareas que involucran la retención y manipulación de información visoespacial. No se hallaron diferencias significativas en la resolución de tareas verbales. Estos resultados sugieren que la experiencia en arquitectura podría conducir a un desempeño conductual mejorado en procesos cognitivos correspondientes a la memoria de trabajo visoespacial. Se discuten los alcances de la presente exploración y las instancias necesarias para la validación de estas observaciones. Se sugiere la realización de nuevos estudios que integren seguimiento longitudinal y tecnologías de neuroimagen.

Music Making and Neuropsychological Aging: A Review

Aging is associated with a decline in social understanding and general cognition. Both are integral to wellbeing and rely on similar brain regions. Thus, as the population ages, there is a growing need for knowledge on the types of activities that maintain brain health in older adulthood. Active engagement in music making might be one such activity because it places a demand on brain networks tapping into multisensory integration, learning, reward, and cognition. It has been hypothesized that this demand may promote plasticity in the frontal and temporal lobes by taxing cognitive abilities and, hence, increase resistance to age-related neurodegeneration. We examine research relevant to this hypothesis and note that there is a lack of intervention studies with a well-matched control condition and random assignment. Thus, we discuss potential causal mechanisms underlying training-related neuropsychological changes, and provide suggestions for future research. It is argued that although music training might be a valuable tool for supporting healthy neuropsychological aging and mental wellbeing, well-controlled intervention studies are necessary to provide clear evidence.

New Perspectives on Music in Rehabilitation of Executive and Attention Functions

Modern music therapy, starting around the middle of the twentieth century was primarily conceived to promote emotional well-being and to facilitate social group association and integration. Therefore, it was rooted mostly in social science concepts. More recently, music as therapy began to move decidedly toward perspectives of neuroscience. This has been facilitated by the advent of neuroimaging techniques that help uncover the therapeutic mechanisms for non-musical goals in the brain processes underlying music perception, cognition, and production. In this paper, we focus on executive function (EF) and attentional processes (AP) that are central for cognitive rehabilitation efforts. To this end, we summarize existing behavioral as well as neuroimaging and neurophysiological studies in musicians, non-musicians, and clinical populations. Musical improvisation and instrumental playing may have some potential for EF/AP stimulation and neurorehabilitation. However, more neuroimaging studies are needed to investigate the neural mechanisms for the active musical performance. Furthermore, more randomized clinical trials combined with neuroimaging techniques are warranted to demonstrate the specific efficacy and neuroplasticity induced by music-based interventions.

Absolute Pitch and Musical Expertise Modulate Neuro-Electric and Behavioral Responses in an Auditory Stroop Paradigm

Musicians have considerable experience naming pitch-classes with verbal (e.g., Doh, Ré, and Mi) and semiotic tags (e.g., musical notation). On the one end of the spectrum, musicians can identify the pitch of a piano tone or quality of a chord without a reference tone [i.e., absolute pitch (AP) or relative pitch], which suggests strong associations between the perceived pitch information and verbal labels. Here, we examined the strength of this association using auditory versions of the Stroop task while neuro-electric brain activity was measured using high-density electroencephalography. In separate blocks of trials, participants were presented with congruent or incongruent auditory words from English language (standard auditory Stroop), Romanic solemnization, or German key lexicons (the latter two versions require some knowledge of music notation). We hypothesized that musically trained groups would show greater Stroop interference effects when presented with incongruent musical notations than non-musicians. Analyses of behavioral data revealed small or even non-existent congruency effects in musicians for solfège and keycodes versions of the Stroop task. This finding was unexpected and appears inconsistent with the hypothesis that musical training and AP are associated with high strength response level associations between a perceived pitch and verbal label. The analyses of event-related potentials revealed three temporally distinct modulations associated with conflict processing. All three modulations were larger in the auditory word Stroop than in the other two versions of the Stroop task. Only AP musicians showed significant congruity effects around 450 and 750 ms post-stimulus when stimuli were presented as Germanic keycodes (i.e., C or G). This finding suggests that AP possessors may process alpha-numeric encodings as word forms with a semantic value, unlike their RP possessing counterparts and non-musically trained individuals. However, the strength of musical conditional associations may not exceed that of standard language in speech.
