Neurological and psychiatric diseases and their unique cognitive profiles: implications for nursing practice and research

Contributions of animal models of cognitive disorders to neuropsychopharmacology

Cognitive disorders and symptoms are key features of many mental and neurological diseases, with a large spectrum of impaired domains. Because of their possible evolution and detrimental functioning impact, they are a major pharmacological target for both symptomatic and disease-modifier drugs, while few cognitive enhancers have been marketed with an insufficient efficiency. It explains the need to model these cognitive disorders beyond the modelization of mental or neurological diseases themselves. According to the experimental strategy used to induce cognitive impairment, three categories of models have been identified: neurotransmission-driven models; pathophysiology-driven models; environment-driven models. These three categories of models reflect different levels of integration of endogenous and exogenous mechanisms underlying cognitive disorders in humans. Their comprehensive knowledge and illustration of their pharmacological modulation could help to propose a renewing strategy of drug development in central nervous system (CNS) field at a time when the academic and industrial invest seems to be declining despite the medical and social burden of brain diseases.

Posttraumatic Stress Syndrome: What Is It?

Readily defined as symptoms consistent with posttraumatic stress disorder (PTSD), but that occur earlier than 30 days after experiencing the traumatic event, posttraumatic stress syndrome (PTSS) is now acknowledged to be a serious health issue. Even so, PTSS often goes unrecognized until an official diagnosis of PTSD is made. Screening tools such as the PTSS-14 have proven reliable in identifying people with PTSS who are at risk of developing PTSD. Through early recognition, providers may be able to intervene, thus alleviating or reducing the effects of a traumatic experience.

Psychiatric Inpatient Nurses' Perceptions of Using Motivational Interviewing

BACKGROUND

Motivational interviewing (MI) is an evidence-based intervention that may help inpatient psychiatric nurses understand patient beliefs about medication while simultaneously strengthening the therapeutic alliance.

OBJECTIVE

Investigate nurses' perceptions regarding use of motivational interviewing after an educational program.

DESIGN

A prospective intervention project.

RESULTS

Agreement with consistent use of MI skills declined at one month. Nurses listened and connected with patients and gained self-awareness of their interactions with other providers.

CONCLUSIONS

Consistent use of MI was used less often than initially believed but having MI focused conversations were useful. When planning MI training for inpatient psychiatric staff nurses, activities must be timely, realistic, and achievable. Work environment is important to making and sustaining the use of MI.

The synergistic effects of HIV, diabetes, and aging on cognition: implications for practice and research

Thanks to highly active antiretroviral therapy, many people infected with HIV will likely live into old age. Although this is a welcome prognosis, new issues are emerging that may complicate the ability to successfully age in this clinical population. HIV and aging independently are related to cognitive impairments, so there are concerns that those aging with HIV may be more at risk of such cognitive impairments. Moreover, highly active antiretroviral therapy itself can create metabolic disorders, such as prediabetes and/or frank type 2 diabetes, which have also been linked to poorer cognitive functioning. Thus, concerns increase that, as people age with HIV and develop comorbid metabolic disorders that may lead to type 2 diabetes, they will be at triple risk of developing cognitive impairments that can impair everyday functioning and reduce quality of life. This article explores these issues and provides implications for practice and research.

Cognitive Consequences of Aging with HIV: Implications for Neuroplasticity and Rehabilitation

Combination active antiretroviral therapy prevents HIV from replicating and ravaging the immune system, thus allowing people to age with this disease. Unfortunately, the synergistic effects of HIV and aging can predispose many to become more at-risk of developing cognitive deficits which can interfere with medical management, everyday functioning, and quality of life. The purpose of this article is to describe the role of cognitive reserve and neuroplasticity on cognitive functioning in those aging with this disease. Specifically, the role of environment and the health of these individuals can compromise cognitive functioning. Fortunately, some cognitive interventions such as prevention and management of co-morbidities, cognitive remediation therapy, and neurotropic medications may be of value in preventing and rehabilitating the cognitive consequences of aging with HIV. Novel approaches such as cognitive prescriptions, transcranial direct stimulation, and binaural beat therapy may also be considered as possible techniques for cognitive rehabilitation.
