As the elderly population grows the impact of age associated cognitive decline as well as neurodegenerative diseases such as Alzheimer's disease and dementia will increase. Ageing is associated with consistent impairments in cognitive processes (e.g., processing speed, memory, executive function and learning) important for work, well-being, life satisfaction and overall participation in society. Recently, there has been increased effort to conduct research examining methods to improve cognitive function in older citizens. Cognitive training has been shown to improve performance in some cognitive domains; including memory, processing speed, executive function and attention in older adults. These cognitive changes are thought to be related to improvements in brain connectivity and neural circuitry. Bacopa monnieri has also been shown to improve specific domains of cognition, sensitive to age associated cognitive decline (particularly processing speed and memory). These Bacopa monnieri dependent improvements may be due to the increase in specific neuro-molecular mechanisms implicated in the enhancement of neural connections in the brain (i.e. synaptogenesis). In particular, a number of animal studies have shown Bacopa monnieri consumption upregulates calcium dependent kinases in the synapse and post-synaptic cell, crucial for strengthening and growing connections between neurons. These effects have been shown to occur in areas important for cognitive processes, such as the hippocampus. As Bacopa monnieri has shown neuro-molecular mechanisms that encourage synaptogenesis, while cognitive training enhances brain connectivity, Bacopa monnieri supplementation could theoretically enhance and strengthen synaptic changes acquired through cognitive training. Therefore, the current paper hypothesises that the combination of these two interventions could improve cognitive outcomes, over and above the effects of administrating these interventions independently, as an effective treatment to ameliorate age associated cognitive decline.

OBJECTIVE: To assess benefits of mindfulness meditation and cognitive behavioral therapy (CBT)-based intervention for opioid-treated chronic low back pain (CLBP).
DESIGN: 26-week parallel-arm pilot randomized controlled trial (Intervention and Usual Care versus Usual Care alone).
SUBJECTS: . Adults with CLBP, prescribed≥30 mg/day of morphine-equivalent dose (MED) for at least 3 months.
METHODS: The intervention comprised eight weekly group sessions (meditation and CLBP-specific CBT components) and 30 minutes/day, 6 days/week of at-home practice. Outcome measures were collected at baseline, 8, and 26 weeks: primary-pain severity (Brief Pain Inventory) and function/disability (Oswestry Disability Index); secondary-pain acceptance, opioid dose, pain sensitivity to thermal stimuli, and serum pain-sensitive biomarkers (Interferon-γ; Tumor Necrosis Factor-α; Interleukins 1ß and 6; C-reactive Protein).
RESULTS: Thirty-five (21 experimental, 14 control) participants were enrolled and completed the study. They were 51.8± 9.7 years old, 80% female, with severe CLBP-related disability (66.7 ± 11.4), moderate pain severity (5.8 ± 1.4), and taking 148.3 ± 129.2 mg/day of MED. Results of the intention-to-treat analysis showed that, compared with controls, the meditation-CBT group reduced pain severity ratings during the study (P = 0.045), with between-group difference in score change reaching 1 point at 26 weeks (95% Confidence Interval: 0.2,1.9; Cohen's d = 0.86), and decreased pain sensitivity to thermal stimuli (P<0.05), without adverse events. Exploratory analyses suggested a relationship between the extent of meditation practice and the magnitude of intervention benefits.
CONCLUSIONS: Meditation-CBT intervention reduced pain severity and sensitivity to experimental thermal pain stimuli in patients with opioid-treated CLBP.

BACKGROUND: Depression is one of the most common mental disorders. Finding effective treatments for such a disorder with higher efficiency lower side effects and affordability is an active area of research in psychiatry. This study aimed to comparatively analyze the effects of the cognitive group therapy and aerobic exercises on depression, automatic negative thoughts and dysfunctional attitudes of students at Kermanshah University of Medical Science.
METHODS: In this clinical trial, 46 associate and undergraduate students at Kermanshah University of Medical Science were randomly divided into three groups: cognitive therapy, aerobic exercise, and control. The data was gathered both before and 8 weeks after the intervention. Beck Depression Inventory (BDI-II), automatic negative thoughts (ATQ), and the Dysfunctional Attitude Scale (DAS) were used as the data collection instruments. The data were analyzed with SPSS version 15 using paired samples T-test, chi-square test, Kruskal-Wallis test, and analysis of variance (ANOVA).
RESULTS: Cognitive therapy caused a significant decrease in depression, belief in automatic negative thoughts, and dysfunctional attitudes in comparison to the control group (p<0.05). Although aerobics compared to the control group causes more reductions in the variables, however, It was only meaningful for the depression variable (p=0.049). Cognitive therapy also reduced the variables more than the aerobic exercise, but the decrease was not statistically significant.
CONCLUSIONS: Cognitive group therapy and aerobic exercise are effective in treating depression. For treating depression, aerobic exercise can be used as a therapy itself or along with cognitive-behavioral therapy and pharmacotherapy.

AIMS AND OBJECTIVES: The aim of this study was to investigate the effects of a cognitive behavioural intervention combined with a breathing relaxation exercise on sleep quality and heart rate variability in patients with major depression.
BACKGROUND: Depression is a long-lasting illness with significant effects not only in individuals themselves, but on their family, work and social relationships as well. Cognitive behavioural therapy is considered to be an effective treatment for major depression. Breathing relaxation may improve heart rate variability, but few studies have comprehensively examined the effect of a cognitive behavioural intervention combined with relaxing breathing on patients with major depression.
DESIGN: An experimental research design with a repeated measure was used.
METHODS: Eighty-nine participants completed this study and entered data analysed. The experimental group (n = 43) received the cognitive behavioural intervention combined with a breathing relaxation exercise for four weeks, whereas the control group (n = 46) did not. Sleep quality and heart rate variability were measured at baseline, posttest1, posttest2 and follow-up. Data were examined by chi-square tests, t-tests and generalised estimating equations.
RESULTS: After adjusting for age, socioeconomic status, severity of disease and psychiatric history, the quality of sleep of the experimental group improved, with the results at posttest achieving significance. Heart rate variability parameters were also significantly improved.
CONCLUSIONS: This study supported the hypothesis that the cognitive behavioural intervention combined with a breathing relaxation exercise could improve sleep quality and heart rate variability in patients with major depression, and the effectiveness was lasting.
RELEVANCE TO CLINICAL PRACTICE: The cognitive behavioural intervention combined with a breathing relaxation exercise that included muscle relaxation, deep breathing and sleep hygiene could be provided with major depression during hospitalisation. Through group practice and experience sharing, participants could modulate their heart rate variability and share feeling about good sleep as well relaxation.

IMPORTANCE: Sleep disturbances have been linked to increased morbidity and mortality, yet it is unknown whether improving sleep quality in older adult patients with insomnia alters biomarkers of diabetes and cardiovascular disease risk.
OBJECTIVE: Determine the comparative efficacy of cognitive behavioral therapy (CBT), tai chi chih (TCC), and a sleep seminar control (SS) to reduce multisystem biomarkers of disease risk in older adults with insomnia.
DESIGN: Randomized controlled comparative efficacy trial.
SETTING: Los Angeles community.
PARTICIPANTS: A population-based sample of 109 older adults with chronic and primary insomnia.
INTERVENTION: Random assignment to CBT, TCC, or SS for 2-h group sessions weekly over 4 months with a 16-month evaluation (1 year after follow-up).
MAIN OUTCOME(S) AND MEASURE(S): Multisystem biological risk comprised of 8 biomarkers: high-density lipoprotein, low-density lipoprotein, triglycerides, hemoglobinA1c, glucose, insulin, C-reactive protein, and fibrinogen. Using clinical laboratory cutoffs defined as abnormal, a multisystem risk score was computed representing a sum of the deviation around the cutoffs across the 8 biomarkers. In addition, high risk grouping was classified if subjects exhibited 4 or more biomarkers in the abnormal laboratory range.
RESULTS: An interaction of time-by-treatment-by-high risk group was found (F(4, 197.2)=3.14, p=.02) in which both TCC (p=.04) and CBT (p=.001) showed significantly lower risk scores as compared to SS at 16-months. CBT reduced risk of being in the high risk group at 4-months (odds ratio [OR]=.21 [95% CI, .03-1.47], p<.10) and at 16-months (OR=.06 [95% CI, .005-.669]; p<.01). TCC reduced the risk at 16-months (OR=.10 [95% CI, .008-1.29]; p<.05) but not at 4 months. Of participants who were classified in the high risk category at baseline, improvements in sleep quality, as defined by a clinical severity threshold, reduced the likelihood of being in the high risk group at 16-months, OR=.08 (95% CI, .008-.78); p=.01.
CONCLUSIONS AND RELEVANCE: Participants classified as having high multisystem biological risk at entry and assigned to CBT or TCC show improvements in risk scores after one year follow-up. Given that these clinical biomarkers are associated with cardiovascular, metabolic, and inflammatory disease risk, improving sleep quality has the potential to reduce the risk of chronic disease in older adults with insomnia.

STUDY OBJECTIVES: Despite considerable evidence supporting cognitive behavioral therapy for insomnia (CBT-I) for chronic insomnia, it remains untested within the context of acute insomnia. This study examined the efficacy of a single session of CBT-I, with an accompanying self-help pamphlet, for individuals with acute insomnia.
DESIGN: A pragmatic parallel group randomized controlled trial.
PARTICIPANTS: Forty adults (mean age 32.9± 13.72 y) with Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) defined insomnia disorder, except a self-reported duration of less than 3 mo (i.e., acute insomnia), who reported no previous exposure to CBT-I and were not currently taking medication for sleep.
INTERVENTIONS: A single 60- to 70-min session of CBT-I (n = 20), with an accompanying self-help pamphlet, or wait list control group (n = 20). All subjects were offered a full individual course of CBT-I on completion of the study, regardless of group allocation.
MEASUREMENTS AND RESULTS: Subjects completed sleep diaries and the Insomnia Severity Index (ISI) pretreatment and 1 mo following treatment. There were no between-group differences on baseline ISI scores or subjective sleep continuity. The intervention group reported significantly lower ISI scores than controls (t(38) 2.24, P<0.05) at follow-up. Further, using proposed ISI scores for identifying insomnia caseness (i.e.,≥ 10), 60% of those in the CBT-I group had remitted by 1 mo compared to 15% of those in the control group.
CONCLUSIONS: This single session of cognitive behavioral therapy for insomnia (CBT-I) is sufficiently efficacious for a significant proportion of those with acute insomnia. The results are discussed in terms of integrating this brief form of CBT-I into the"stepped care"model of insomnia.

BACKGROUND: Evidence supports the effectiveness of cognitive behavioural approaches in improving the symptoms of the irritable bowel syndrome (IBS). Duration, cost and resistance of many patients towards a psychological therapy have limited their acceptance. AIM: To evaluate the effectiveness of a psycho-educational intervention on IBS symptoms. METHODS: Sixty-nine IBS patients (72% female) were randomised to an intervention or a wait-list control group. The IBS class consisted of education on a biological mind body disease model emphasising self-efficacy and practical relaxation techniques. RESULTS: Patients in the intervention showed significant improvement on GI symptom severity, visceral sensitivity, depression and QoL postintervention and most of these gains were maintained at 3-month follow-up (Hedge's g = -0.46-0.77). Moderated mediation analyses indicated change in anxiety, visceral sensitivity, QoL and catastrophising due to the intervention had moderate mediation effects (Hedge's g = -0.38 to -0.60) on improvements in GI symptom severity for patients entering the trial with low to average QoL. Also, change in GI symptom severity due to the intervention had moderate mediation effects on improvements in QoL especially in patients with low to average levels of QoL at baseline. Moderated mediation analyses indicated mediation was less effective for patients entering the intervention withhigh QoL. CONCLUSIONS: A brief psycho-educational group intervention is efficacious in changing cognitions and fears about the symptoms of the irritable bowel syndrome, and these changes are associated with clinically meaningful improvement in symptoms and quality of life. The intervention seems particularly tailored to patients with low to moderate quality of life baseline levels.

Cognitive-behavior therapy for problem gambling: a critique of current treatments and proposed new unified approach.
J Ment Health. 2017 Jun;26(3):283-290
Authors: Tolchard B
BACKGROUND: There is evidence supporting the use of cognitive-behavioral therapy (CBT) in the treatment of problem gambling. Despite this, little is known about how CBT works and which particular approach is most effective. This paper aims to synthesize the evidence for current CBT and propose a more unified approach to treatment.
METHODS: A literature review and narrative synthesis of the current research evidence of CBT for the treatment of problem gambling was conducted, focusing on the underlying mechanisms within the treatment approach.
RESULTS: Several CBT approaches were critiqued. These can be divided into forms of exposure therapy (including aversion techniques, systematic desensitization and other behavioral experiments) those focusing on cognitive restructuring techniques (such as reinforcement of nongambling activity, use of diaries, motivational enhancement and audio-playback techniques and third wave techniques including mindfulness. Findings, in relation to the treatment actions, from this synthesis are reported.
CONCLUSIONS: The debate surrounding the treatment of problem gambling has been conducted as an either/or rather than a both/and discourse. This paper proposes a new, unified approach to the treatment of problem gambling that incorporates the best elements of both exposure and cognitive restructuring techniques, alongside the use of techniques borrowed from mindfulness and other CBT approaches.
