BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) has been used to improve cognitive function, but the stimulation protocols are variable and the underlying mechanism is unclear. Therefore, we intend to examine whether 5Hz rTMS with 30% maximum output could improve cognitive functions in senescence-accelerated-prone mouse 8 (SAMP8) through changing synaptic plasticity. METHODS: SAMP8 and senescence-accelerated-prone mouse/resistant 1 (SAMR1) (7-month old male) were randomly divided into 3 groups: SMAP8 rTMS group (P8-rTMS), SMAP8 sham-rTMS group (P8-sham), and SAMR1 sham-rTMS group (R1-sham)...

The rodent parafascicular nucleus (PFn) or the centromedian-parafascicular complex of primates is a posterior intralaminar nucleus of the thalamus related to cortical activation and maintenance of states of consciousness underlying attention, learning and memory. Deep brain stimulation (DBS) of the PFn has been proved to restore arousal and consciousness in humans and to enhance performance in learning and memory tasks in rats. The primary expected effect of PFn DBS is to induce plastic changes in target neurons of brain areas associated with cognitive function...

In contact sports, repetitive concussive brain injury (rCBI) is the prevalent form of head injury seen in athletes. The need for effective treatment is urgent as rCBI has been associated with a host of cognitive, behavioral and neurological complaints. There has been a growing trend in the use of female animals in pre-clinical research, but few studies have investigated possible sex differences following rCBI. The goal of the current study was to determine any differences between male and female C57BL/6J mice on assessments of learning and memory after repetitive concussive injury...

Although lifetime exposure to potentially traumatic events among older adults is fairly high, rates of full-blown post-traumatic stress disorder (PTSD) are estimated at about 4.5%, a rate lower than that for middle-aged and young adults. Nevertheless, PTSD seems to be an under-recognized and under-treated condition in older adults. Assessment and treatment can be challenging in this population for various reasons, including potential cognitive or sensory decline and comorbid mental and physical disorders. This article provides highlights of the empirical research on PTSD in late life, including information on its effects on cognition and physical health...

INTRODUCTION: Insomnia is considered to be a serious public health issue affecting approximately 10% of adults. Chronic insomnia may increase the risk of health problem, psychological vulnerability and proneness to accidents. Cognitive behavioral therapy for insomnia (CBT-I) is recommended as the first line of treatment. Even though CBT-I is widely considered as an effective therapy, 20 to 30% of patients do not respond to this treatment. Mindfulness therapy, known to reduce rumination and stress, could be an interesting complement to enhance CBT-I...

Urinary dysfunction (UD) is a common non-motor feature of Parkinson's disease (PD), and might be secondary to neurodegeneration involving cortical and subcortical brain areas. The possible link between UD and cognitive deficits has never been examined in frontal cortex impairment, and is still not completely understood in PD. In the present study, 94 PD patients underwent a comprehensive motor, cognitive and non-motor assessment. It was shown that 55.3% of patients reported UD, of which 17% needed specific urological treatment...

: Long duration of anesthesia may induce toxicity in the developing brain. However, little is known about the effects of the combination of surgery and anesthesia on the developing brain. The mechanisms for the effects are not clear. To determine these effects, postnatal day 7 male and female Sprague-Dawley rats were exposed to 3% sevoflurane for 2 h with or without right common carotid exposure. Pyrrolidine dithiocarbamate (PDTC), an anti-inflammatory agent, was given 30 min before and 6 h after the carotid exposure...

Specific changes in personality profiles may represent early non-cognitive symptoms of Alzheimer's disease (AD). Evaluating the subject's personality changes may add significant clinical information, as well as help to better understand the interaction between personality change, cognitive decline, and cerebral pathology. With this study we aimed to describe the relationship between personality changes and cerebrospinal fluid (CSF) markers of AD pathology at early clinical stages of the disease. One hundred and ten subjects, of whom 66 cognitively impaired patients (57 with mild cognitive impairment (MCI), and 9 with mild dementia) and 44 healthy controls, had neuropsychological examination as well as lumbar puncture to determine concentrations of CSF biomarkers of AD pathology (amyloid beta1-42 (Aβ1-42), phosphorylated tau (ptau-181), and total-tau (tau))...

Despite the common conception of the dorsal premotor cortex (PMd) as a single brain region, its diverse connectivity profiles and behavioral heterogeneity argue for a differentiated organization of the PMd. A previous study revealed that the right PMd is characterized by a rostro-caudal and a ventro-dorsal distinction dividing it into five subregions: rostral, central, caudal, ventral and dorsal. The present study assessed whether a similar organization is present in the left hemisphere, by capitalizing on a multimodal data-driven approach combining connectivity-based parcellation (CBP) based on meta-analytic modeling, resting-state functional connectivity, and probabilistic diffusion tractography...

Given the central role of stress-responsive neurophysiology in mental and physical health, it is important to understand how particular patterns of stress responsivity may become entrained by the early caregiving environment. In this study we investigated links between maternal depression and anxiety symptom profiles and within-infant development of hypothalamic-pituitary-adrenal (HPA) axis responses from 6 to 18 months of life. Associations with infant cognitive and social-emotional development were also tested to gauge the adjustment implications of HPA response trajectories...

The Mediterranean diet has demonstrated efficacy for improving cardiovascular and cognitive health. However, a traditional Mediterranean diet delivers fewer serves of dairy and less dietary calcium than is currently recommended in Australia, which may limit long-term sustainability. The present study aims to evaluate whether a Mediterranean diet with adequate dairy and calcium can improve cardiovascular and cognitive function in an at-risk population, and thereby reduce risk of cardiovascular disease (CVD) and cognitive decline...

While the efficacy of cognitive-behavioral treatment (CBT) approaches for childhood functional abdominal pain (FAP) is well-established for child outcomes, only a few studies have reported on parent-specific outcomes. This randomized controlled pilot trial analyzed effects of a group CBT on maternal variables (i.e., pain-related behavior, worries and self-efficacy, as well as general psychosocial strain). Methods: The sample constituted of 15 mothers in the intervention group (IG) and 14 mothers in the waitlist control group (WLC)...
