The role of early fine and gross motor development on later motor and cognitive ability

The aim of this study was to determine whether information obtained from measures of motor performance taken from birth to 4 years of age predicted motor and cognitive performance of children once they reached school age. Participants included 33 children aged from 6 years to 11 years and 6 months who had been assessed at ages 4 months to 4 years using the ages and stages questionnaires (ASQ: [Squires, J. K., Potter, L., & Bricker, D. (1995). The ages and stages questionnaire users guide. Baltimore: Brookes]). These scores were used to obtain trajectory information consisting of the age of asymptote, maximum or minimum score, and the variance of ASQ scores. At school age, both motor and cognitive ability were assessed using the McCarron Assessment of Neuromuscular Development (MAND: [McCarron, L. (1997). McCarron assessment of neuromuscular development: Fine and gross motor abilities (revised ed.). Dallas, TX: Common Market Press.]), and the Wechsler Intelligence Scale for Children-Version IV (WISC-IV: [Wechsler, D. (2004). WISC-IV integrated technical and interpretive manual. San Antonio, Texas: Harcourt Assessment]). In contrast to previous research, results demonstrated that, although socio-economic status (SES) predicted fine motor performance and three of four cognitive domains at school age, gestational age was not a significant predictor of later development. This may have been due to the low-risk nature of the sample. After controlling for SES, fine motor trajectory information did not account for a significant proportion of the variance in school aged fine motor performance or cognitive performance. The ASQ gross motor trajectory set of predictors accounted for a significant proportion of the variance for cognitive performance once SES was controlled for. Further analysis showed a significant predictive relationship for gross motor trajectory information and the subtests of working memory and processing speed. These results provide evidence for detecting children at risk of developmental delays or disorders with a parent report questionnaire prior to school age. The findings also add to recent investigations into the relationship between early motor development and later cognitive function, and support the need for ongoing research into a potential etiological relationship.

Do motor skills in infancy and early childhood predict anxious and depressive symptomatology at school age

Research has identified a relationship between social-emotional problems and motor impairment in both pre-school and school-age children. The aim of the current study was to determine how motor performance in infancy and early childhood is related to levels of anxious and depressive symptomatology at age 6-12 years. Fifty participants were assessed by their parents 11 times between the ages of 4 months and 4 years using the Ages and Stages Questionnaire (ASQ), and once between the age of 6 and 12 years using the Child Behavior Checklist (CBCL). The ASQ scores were used to obtain the stability (variance) of fine and gross motor performance. Once gestational age, sex and age of testing were taken into account, the stability of gross motor scores predicted both the anxiety/depression measure and the anxious score from the CBCL. It appears that how variable a young childs gross motor development is from 4 months to 4 years predicts the level of anxious/depressive symptoms at school age. These findings may assist in the early identification of children at risk of anxiety disorders and depression at school age.

A Meta-Analysis of Randomised Placebo-Controlled Treatment Trials for Depression and Anxiety in Parkinson's Disease

Background Psychopharmacotherapy currently constitutes the first-line treatment for depression and anxiety in Parkinson’s disease (PD) however the efficacy of antidepressant treatments in PD is unclear. Several alternative treatments have been suggested as potentially more viable alternatives including dopamine agonists, repetitive transcranial magnetic stimulation, and cognitive behavioural therapy (CBT). Method A meta-analysis of randomised placebo-controlled trials for depression and/or anxiety in PD was conducted to systematically examine the efficacy of current treatments for depression and anxiety in PD. Results Nine trials were included. There was only sufficient data to calculate a pooled effect for antidepressant therapies. The pooled effect of antidepressants for depression in PD was moderate but non-significant (d = .71, 95% CI = −1.33 to 3.08). The secondary effect of antidepressants on anxiety in PD was large but also non-significant (d = 1.13, 95% CI = −.67 to 2.94). Two single-trials of non-pharmacological treatments for depression in PD resulted in significant large effects; Omega-3 supplementation (d = .92, 95% CI = .15 to 1.69) and CBT (d = 1.57, 95% CI = 1.06 to 2.07), and warrant further exploration. Conclusions There remains a lack of controlled trials for both pharmacological and non-pharmacological treatments for depression and anxiety in PD which limits the conclusions which can be drawn. While the pooled effects of antidepressant therapies in PD were non-significant, the moderate to large magnitude of each pooled effect is promising. Non-pharmacological approaches show potential for depression in PD however more research is required.

Limb and gender differences in the development of coordination in early infancy

Young infants produce a variety of spontaneous arm and leg movements in the first few months of life. Coordination of leg joints has been extensively investigated, whereas arm joint coordination has mainly been investigated in the sitting position in the context of early reaching and grasping. The current study investigated arm and leg joint coordination of movements produced in the supine position in 10 fullterm infants aged 6, 12 and 18 weeks. Longitudinal comparisons within limbs (intralimb) as well as between limbs (interlimb, ipsilateral and contralateral) were made as well as an exploration of differences in the development for boys and girls. The relationship between the joint angles was examined by measuring pair-wise cross-correlation functions for the angular displacement curves of the leg (hip, knee and ankle) and arm (shoulder, elbow and wrist) joints of both the right and left side. Both the arms and legs were found to follow a similar pattern of intralimb coordination, although the leg joints were more tightly coupled than the arm joints, particularly the proximal with the middle joint. In support of earlier findings, differences in the development of the right and left side were identified. In addition, gender differences in joint coordination were found for both intralimb and interlimb coordination. This contrasts with the view that gender differences in motor development may be primarily a result of environmental influences.

Spontaneous kicking in fullterm and preterm infants: Are there leg asymmetries?

Abstract In the first few months of life, infants display spontaneous kicking which has been implicated as an important precursor to the development of later voluntary motor control. In the present study, the development of both intralimb and interlimb coordination in fullterm and low-risk preterm infants was examined by recording spontaneous kicking at 4 weekly intervals from 4 to 24 weeks of age. The relationship between the joint angles over this period was examined by measuring pairwise cross-correlation functions for the angular displacement curves of the hip, knee and ankle joints. In contrast to previous studies, intralimb coordination for both right and left legs was examined, and it was found that the legs produced different patterns of development. These patterns varied depending on which joint pair was investigated, and there was also evidence that leg asymmetries may be different for preterm and fullterm infants. This has possible implications for later hand and leg preferences. Interlimb coordination was also examined, and it appears that different patterns of development emerge for interlimb and intralimb coordination. PsycINFO classification: 2330; 2800

A waitlist-controlled trial of group cognitive behavioural therapy for depression and anxiety in Parkinson's disease

BackgroundThe aim of this study was to evaluate the efficacy of a group Cognitive Behavioural Therapy (CBT) treatment for depression and anxiety in Parkinson’s disease (PD).MethodsA waitlist-controlled trial design was used. Eighteen adults with PD and a comorbid DSM-IV-TR diagnosis of depression and/or anxiety were randomised to either Intervention (8-week group CBT treatment) or Waitlist (8-week clinical monitoring preceding treatment). The Depression, Anxiety, Stress Scale-21 (DASS-21) was the primary outcome. Assessments were completed at Time 1 (pretreatment), Time 2 (posttreatment/post-waitlist) and 1-month and 6-month follow-ups.ResultsAt Time 2, participants who received CBT reported greater reductions in depression (Mchange = -2.45) than Waitlist participants (Mchange = .29) and this effect was large, d = 1.12, p = .011. Large secondary effects on anxiety were also observed for CBT participants, d = .89, p = .025. All treatment gains were maintained and continued to improve during the follow-up period. At 6-month follow-up, significant and large effects were observed for both depression (d = 2.07) and anxiety (d = 2.26).ConclusionsGroup CBT appears to be an efficacious treatment approach for depression and anxiety in PD however further controlled trials with larger numbers of participants are required.Trial registrationAustralian New Zealand Clinical Trials Registry (Trial ID: ACTRN12610000455066)

Treatment of depression and anxiety in Parkinson's Disease: A pilot study using group cognitive behavioural therapy

Depression and anxiety affect up to 50% of people with Parkinsons Disease (PD) (Marsh, 2000; Murray, 1996), however, few studies have examined the effectiveness of psychological treatment. This study examined the effectiveness of group cognitive behaviour therapy (CBT) in treating depression and anxiety in PD. Four participants, aged between 56 and 81 years, who had been diagnosed with PD and suffering from depression and/or anxiety were included in the study. The results suggested that CBT was effective in treating depression and anxiety in PD. Furthermore, the results supported that the gains were maintained at 1-month follow-up.

Activities of daily living, depression, and quality of life in Parkinson's disease.

This study examined whether activities of daily living (ADL) mediate the relationship between depression and health-related quality of life (HR-QOL) in people with Parkinsons disease (PD). A cross-sectional, correlational research design examined data from 174 participants who completed the Geriatric Depression Scale (GDS-15), Parkinsons Disease Questionnaire-39 (PDQ-39), and Unified Parkinsons Disease Rating Scale-section 2 (UPDRS-section 2 [ADL]). Multiple Regression Analysis (MRA) was used to examine the mediator model. Depression and ADL significantly (p<.001) predicted HR-QOL, and depression significantly (p<.001) predicted ADL. Whilst ADL did not impact on the relationship between depression and HR-QOL, there was a significant (p<.001) indirect effect of depression on HR-QOL via ADL, suggesting both direct and indirect (via ADL) effects of depression on HR-QOL. The magnitude of this effect was moderate (R 2 = .13). People with PD who report depression also experience greater difficulty completing ADL, which impacts upon their HR-QOL. It is recommended that clinicians adopt a multidisciplinary approach to care by combining pharmacological treatments with psycho/occupational therapy, thereby alleviating the heterogeneous impact of motor and non-motor symptoms on HR-QOL in people with PD.

Identifying needs, burden, and distress of carers of people with Frontotemporal dementia compared to Alzheimer’s disease

The literature on carers of people with Frontotemporal dementia (FTD) is negligible compared to the vast literature on carers of people with Alzheimer’s disease (AD), and little research has compared the two groups. Research has mainly focused on identifying the behavioural characteristics of people with FTD or AD. The impact of these behaviours on the psychological well-being of carers of people with FTD is relatively unexplored. This study investigated the needs, burden, and extent of depression and anxiety in carers of people with FTD (n = 30) compared to carers of people with AD (n = 30). Findings indicated that needs of carers of people with FTD were significantly higher than those of the carers of people with AD. The elevated needs were related to the younger onset of FTD, financial dissatisfaction, typical FTD characteristics, and access to appropriate services, information and support. Results also suggested that female carers were more likely to report a greater severity and impact of disruptive symptoms associated with FTD. No significant differences were found between the two groups on carers’ levels of burden, depression or anxiety. In order to address the needs of carers of people with FTD, we recommend specific educational and support programs, raising community awareness and understanding, and tailoring existing domiciliary services and activities for people with FTD.

Personality affects aspects of health-related quality of life in Parkinson's disease via psychological coping strategies

BACKGROUND Personality traits influence health-related quality of life (HRQoL) in Parkinsons disease (PD). Further, an individuals personality traits can influence the strategies they use to cope with a particular stressful situation. However, in PD, the interplay between personality traits, choice of coping strategy, and their subsequent effect on HRQoL remains unclear. OBJECTIVE The objective of this study was to examine whether personality (neuroticism and extraversion) indirectly affects HRQoL through the use of specific psychological coping strategies. METHODS One hundred and forty-six patients with PD completed questionnaires on personality (Big Five Aspects Scale; BFAS), coping (Ways of Coping Questionnaire; WCQ), and mood-specific (Depression, Anxiety and Stress Scale; DASS-21) and disease-specific HRQoL (Parkinsons Disease Questionnaire; PDQ-39). RESULTS After controlling for gender, age at diagnosis, and age at testing, the emotion-focused coping strategy of escape-avoidance was significantly correlated with neuroticism and certain aspects of HRQoL (cognitive impairment and social support). This suggests that neurotic personality traits may negatively impact on some aspects of HRQoL due to an increased use of escape-avoidance coping strategies. By contrast, planned problem-solving and escape-avoidance coping strategies were both significantly linked to extraversion and interpersonal and mood-related domains of HRQoL. This suggests that extraversion may positively impact on some aspects of HRQoL due to patients adopting greater planned, problem-solving coping strategies, and using fewer escape-avoidance coping mechanisms. CONCLUSIONS Psychological interventions aimed at targeting maladaptive coping strategies, such as the use of escape-avoidance coping, may be effective in minimising the negative impact of neuroticism on HRQoL in PD.
