Schizophrenia is a chronic, severe, and debilitate mental disorder that causing disability. Factors that causing disability is cognitive impairment. Cognitive impairment caused by disturbance in neurodevelopmental process of the brain that related to Dopaminergic, GABA-ergic, and Acethylcholinergic pathway. Cognitive Enhancement Therapy is additional therapy to recovery the cognitive function. CET facilitated repairmenin socio and non-socio cognitive function, encourage patient behaviour related social condition, develop patient understanding of schizophrenia and the impact on cognitive impair- ment, and rehabilitation program that characterised of an experiential and exercise to repair the non-social cognitive function (attention, memmory, and problem solving). CET shows improvement in early or late onset of schizophrenia. Pa- tients who got CET can back to work. Now, CET is used for early intervention in cognitive impairment in Schizophrenia. CET was also developed in patients with Schizoaffective, Schizophrenia comorbid with drug abuse, and patientswith au- tism. Hopefully, the improvement onquality of life patient with schizophrenia can achieve with combination pharmacother- apy and Cognitive Enhancement Therapy.

The Brain

The brain has a high metabolic rate and its metabolism is almost entirely restricted to oxidative utilisation of glucose. These factors emphasise the extreme dependence of neural tissue on a stable and adequate supply of glucose. Whereas initially it was thought that only glucose deprivation (i.e. under hypoglycaemic conditions) can affect brain function, it has become apparent that low-level fluctuations in central availability can affect neural and consequently, cognitive performance. In the present paper the impact of diet-based glycaemic response and glucose regulation on cognitive processes across the lifespan will be reviewed. The data suggest that although an acute rise in blood glucose levels has some short-term improvements of cognitive function, a more stable blood glucose profile, which avoids greater peaks and troughs in circulating glucose is associated with better cognitive function and a lower risk of cognitive impairments in the longer term. Therefore, a habitual diet that secures optimal glucose delivery to the brain in the fed and fasting states should be most advantageous for the maintenance of cognitive function. Although the evidence to date is promising, it is insufficient to allow firm and evidence-based nutritional recommendations. The rise in obesity, diabetes and metabolic syndrome in recent years highlights the need for targeted dietary and lifestyle strategies to promote healthy lifestyle and brain function across the lifespan and for future generations. Consequently, there is an urgent need for hypothesis-driven, randomised controlled trials that evaluate the role of different glycaemic manipulations on cognition.

Group 1

Angioreconstructive interventions are generally known to be of prophylactic value for cerebrovascular diseases (CVD). At the same time, their prognosis in comorbid patients, particularly in those with type 2 diabetes (T2D), have been insufficiently covered.Objective: to study the impact of T2D on cognitive functions after carotid angioplasty with stenting (CAS)Patients and methods. CAS was performed in 99 patients with chronic CVD. Group 1 consisted of 51 patients (median age, 64.5 years) without carbohydrate metabolism disorders. Group 2 included 48 patients (median age, 64 years) with T2D. Over time, all the patients underwent clinical, neurological, and neuropsychological examinations, general clinical and biochemical blood tests, duplex scanning of the brachiocephalic arteries, and magnetic resonance imaging (MRI) of the brain. Blood flow in the middle cerebral artery was monitored to assess the embolic and hemodynamic situation during a CAS procedure.Results and discussion. The baseline frequency of neurocognitive impairment was almost the same (75%) in both groups; however, the impairment was more obvious in patients with T2D. Re-examination in Group 1 patients immediately after intervention revealed slight positive cognitive changes, while the patients with T2D showed a decrease in the indicators of mental functions. The improved ability to abstract and increase the level of generalization of functions appeared in T2D patients only 2 months after intervention. Post-CAS MRI revealed ipsilateral acute ischemic foci (AIF) in the brain substance in 11 (22%) patients of Group 1 and in 24 (50%) with concomitant T2D. Comparison of neuroimaging data with cognitive function assessments for the entire group of the examinees established deterioration in the cognitive status in patients with new ischemic brain changes detected after intervention.Conclusion. CVD concurrent with T2D usually contributes to deterioration in the cognitive status. Angioreconstructive interventions, in particular CAS, are frequently accompanied by the identification of AIF (including «silent» ones) that can cause a transient deterioration in cognitive functions. When planning angioreconstructive interventions in patients with T2D, the question arises of predicting such risks and possible neuroprotective methods.

The Impact

The prevalence of cognitive impairment caused by neurodegenerative diseases and other neurologic disorders associated with aging is expected to rise dramatically between now and year 2050, when the population of Americans aged 65 or older will nearly double. Cognitive impairment also commonly occurs in other neurologic conditions, as well as in non-neurologic medical disorders (and their treatments), idiopathic psychiatric illnesses, and adult neurodevelopmental disorders. Cognitive impairment can thus infiltrate all aspects of healthcare, making it necessary for clinicians and clinical researchers to have an integrated knowledge of the spectrum of adult cognitive disorders. The Oxford Handbook of Adult Cognitive Disorders is meant to serve as an up-to-date, scholarly, and comprehensive volume covering most diseases, conditions, and injuries resulting in impairments in cognitive function in adults. Topics covered include normal cognitive and brain aging, the impact of medical disorders (e.g., cardiovascular, liver, pulmonary) and psychiatric illnesses (e.g., depression and bipolar disorder) on cognitive function, adult neurodevelopmental disorders (e.g., Down Syndrome, Attention Deficit/Hyperactivity Disorder), as well as the various neurological conditions (e.g., Alzheimer’s disease, chronic traumatic encephalopathy, concussion). A section of the Handbook is also dedicated to unique perspectives and special considerations for the clinicians and clinical researchers, covering topics such as cognitive reserve, genetics, diversity, and neuroethics. The target audience of this Handbook includes: (1) clinicians, particularly psychologists, neuropsychologists, neurologists (including behavioral and cognitive neurologists), geriatricians, and psychiatrists (including neuropsychiatrists), who provide clinical care and management for adults with a diverse range of cognitive disorders; (2) clinical researchers who investigate cognitive outcomes and functioning in adult populations; and (3) graduate level students and post-doctoral trainees studying psychology, clinical neuroscience, and various medical specialties.

The Impact

Information support robots (ISRs) have the potential to assist older people living alone to have an independent life. However, the effects of ISRs on the daily activity, especially the sleep patterns, of older people have not been clarified; moreover, it is unclear whether the effects of ISRs depend on the levels of cognitive function. To investigate these effects, we introduced an ISR into the actual living environment and then quantified induced changes according to the levels of cognitive function. Older people who maintained their cognitive function demonstrated the following behavioral changes after using the ISR: faster wake-up times, reduced sleep duration, and increased amount of activity in the daytime (p < 0.05, r = 0.77; p < 0.05, r = 0.89, and p < 0.1, r = 0.70, respectively). The results suggest that the ISR is beneficial in supporting the independence of older people living alone since living alone is associated with disturbed sleep patterns and low physical activity. The impact of the ISR on daily activity was more remarkable in the subjects with high cognitive function than in those with low cognitive function. These findings suggest that cognitive function is useful information in the ISR adaptation process. The present study has more solid external validity than that of a controlled environment study since it was done in a personal residential space.

Abstract Objectives Mental illness and cognitive functioning may be independently associated with nursing home use. We investigated the strength of the association between baseline (1998) psychiatric history, 8-year cognitive function trajectories, and prospective incidence of nursing home use over a 10-year period while accounting for relevant covariates in U.S. adults aged 65 and older. We hypothesized that self-reported baseline history of psychiatric, emotional, or nervous problems would be associated with a greater risk of nursing home use and that cognition trajectories with the greatest decline would be associated with a subsequent higher risk of nursing home use. Methods We used 8 waves (1998–2016) of Health and Retirement Study data for adults aged 65 years and older. Latent class mixture modeling identified 4 distinct cognitive function trajectory classes (1998–2006): low-declining, medium-declining, medium-stable, and high-declining. Participants from the 1998 wave (N = 5,628) were classified into these 4 classes. Competing risks regression analysis modeled the subhazard ratio of nursing home use between 2006 and 2016 as a function of baseline psychiatric history and cognitive function trajectories. Results Psychiatric history was independently associated with greater risk of nursing home use (subhazard ratio [SHR] 1.26, 95% confidence interval [CI] 1.06–1.51, p &lt; .01), net the effects of life course variables. Furthermore, “low-declining” (SHR 2.255, 95% CI 1.70–2.99, p &lt; .001) and “medium-declining” (2.103, 95% CI 1.69–2.61, p &lt; .001) trajectories predicted increased risk of nursing home use. Discussion Evidence of these associations can be used to educate policymakers and providers about the need for appropriate psychiatric training for staff in community-based and residential long-term care programs.

The Brain

Central nervous system (CNS) diseases are one of the top causes of death worldwide. As there is a difficulty of drug penetration into the brain due to the blood–brain barrier (BBB), many CNS drugs treatments fail in clinical trials. Hence, there is a need to develop effective CNS drugs following strategies for delivery to the brain by better selecting them as early as possible during the drug discovery process. The use of in vitro BBB models has proved useful to evaluate the impact of drugs/compounds toxicity, BBB permeation rates and molecular transport mechanisms within the brain cells in academic research and early-stage drug discovery. However, these studies that require biological material (animal brain or human cells) are time-consuming and involve costly amounts of materials and plastic wastes due to the format of the models. Hence, to adapt to the high yields needed in early-stage drug discoveries for compound screenings, a patented well-established human in vitro BBB model was miniaturized and automated into a 96-well format. This replicate met all the BBB model reliability criteria to get predictive results, allowing a significant reduction in biological materials, waste and a higher screening capacity for being extensively used during early-stage drug discovery studies.

Abstract We hypothesized that bone may secrete hormones that regulate energy metabolism and reproduction. Testing this hypothesis revealed that the osteoblast-specific secreted protein osteocalcin is a hormone regulating glucose homeostasis and male fertility by signaling through a GPCR, Gprc6a, expressed in pancreatic β bells and Leydig cells of the testes. The systematic exploration of osteocalcin biology, revealed that it regulates an unexpectedly large spectrum of physiological functions in the brain and peripheral organs and that it has most features of an antigeromic molecule. As will be presented at the meeting, this body of work suggests that harnessing osteocalcin for therapeutic purposes may be beneficial in the treatment of age-related diseases such as depression, age-related memory loss and the decline in muscle function seen in sarcopenia.

Psychotherapy is a comprehensive biological treatment modifying complex underlying cognitive, emotional, behavioral, and regulatory responses in the brain, leading patients with mental illness to a new interpretation of the sense of self and others. Psychotherapy is an art of science integrated with psychology and/or philosophy. Neurological sciences study the neurological basis of cognition, memory, and behavior as well as the impact of neurological damage and disease on these functions, and their treatment. Both psychotherapy and neurological sciences deal with the brain; nevertheless, they continue to stay polarized. Existential phenomenological psychotherapy (EPP) has been in the forefront of meaning-centered counseling for almost a century. The phenomenological approach in psychotherapy originated in the works of Martin Heidegger, Ludwig Binswanger, Medard Boss, and Viktor Frankl, and it has been committed to accounting for the existential possibilities and limitations of one’s life. EPP provides philosophically rich interpretations and empowers counseling techniques to assist mentally suffering individuals by finding meaning and purpose to life. The approach has proven to be effective in treating mood and anxiety disorders. This narrative review article demonstrates the development of EPP, the therapeutic methodology, evidence-based accounts of its curative techniques, current understanding of mood and anxiety disorders in neurological sciences, and a possible converging path to translate and integrate meaning-centered psychotherapy and neuroscience, concluding that the EPP may potentially play a synergistic role with the currently prevailing medication-based approaches for the treatment of mood and anxiety disorders.
