RESUMO

There are a plethora of cognitive sequelae in addition to neglect and extinction that arise with unilateral right hemispheric stroke (RHS). Cognitive deficits following non-dominant (right) hemisphere stroke are common with unilateral neglect and extinction being the most recognized examples. The severity of RHS is usually underestimated by the National Institutes of Health Stroke Scale (NIHSS), which in terms of lateralized right hemisphere cognitive deficits, tests only for visual inattention/extinction. They account for 2 out of 42 total possible points. Additional neuropsychiatric sequelae include but are not limited to deficiencies in affective prosody comprehension and production (aprosodias), understanding and expressing facial emotions, empathy, recognition of familiar faces, anxiety, mania, apathy, and psychosis. These sequelae have a profound impact on patients' quality of life; affecting communication, interpersonal relationships, and the ability to fulfill social roles. They also pose additional challenges to recovery. There is presently a gap in the literature regarding a cohesive overview of the significant cognitive sequelae following RHS. This paper serves as a narrative survey of the current understanding of the subject, with particular emphasis on neuropsychiatric poststroke syndromes not predominantly associated with left hemisphere lesions (LHL), bilateral lesions, hemiplegia, or paralysis. A more comprehensive understanding of the neuropsychological consequences of RHS extending beyond the typical associations of unilateral neglect and extinction may have important implications for clinical practice, including the ways in which clinicians approach diagnostics, treatment, and rehabilitation.

RESUMO

Substance use disorders (SUDs) among older persons are among the fastest growing health problems in the United States. The number of older persons is projected to exceed 72.1 million persons by 2030, following a trend of general population growth in the mid-1940s to 1960s. The generation, known as "baby boomers," who refashioned drug use during their 20-30s, are increasingly continuing drug habits into later life. This review aims to assess the epidemiology, impact, and treatment of geriatric SUDs. Academic databases including PubMed, PsychInfo, Ovid, and Medline, were queried up to December 2018 for terms of "geriatric," "older," "elderly," "substance abuse," "drug," "drug use," "drug abuse," "drug dependency," "illicit drugs," and "geriatric psychiatry." Articles identified included 17 government documents, 29 studies based upon government documents, 43 studies not related to US government surveys, 19 review articles, 9 commentary pieces, 4 newspaper articles, 2 textbooks, and 1 published abstract. Evaluated studies and documents together suggest that older individuals are using illicit drugs and meeting criteria for SUDs at higher rates than previous geriatric cohorts resulting in substantial negative impacts on medical and psychiatric conditions. These findings represent a novel trend since previous cohorts of older individuals were thought to rarely use illicit substances. Current treatment models are inadequate to address the new wave of older individuals with SUDs. The fields of geriatrics, addiction, and geriatric psychiatry must work together to establish comprehensive care models and treatment modalities for addressing this emerging public health concern.

RESUMO

Correctional systems, already struggling to meet the basic and functional requirements of older prisoners, will be further challenged by the increasing medical and psychiatric needs of this population. Mental health and general medical care for older adults requires specific on-site or consultation expertise in geriatric medicine and psychiatry, as well as potential changes in infrastructure, both of which may be prohibitively expensive. However, compassionate and effective treatment of older prisoners requires that prison and legal systems facilitate this expert care. To address this situation, strategic revisions of the criminal justice system are needed to alleviate prison overcrowding and consequent inadequate medical care for inmates, especially the elder ones. The unique, age-related demands of this older population predict an increased need for forensic psychiatrists with a thorough knowledge and expertise in geriatrics, as more forensic psychiatric evaluations will be needed before trial in both civil and criminal cases, during incarceration, and at the time of parole. In this article, we review the current state of elder inmates in correctional institutions and advocate for increased geriatric training for forensic psychiatrists in anticipation of this growing need.

RESUMO

Posttraumatic stress disorder (PTSD) is a chronic debilitating psychiatric disorder characterized by symptoms of re-experience, avoidance, and hyperarousal that can arise immediately or many years after exposure to a traumatic event and injury. Although extensive research has been done over the past 30 years, the etiology of PTSD remains largely unknown. Several neurobiological systems have been implicated in the pathophysiology and vulnerability for developing PTSD; however, first-line pharmacotherapies are limited. Less than 30% achieve full remission, and even then, approved pharmacological treatments often take weeks for therapeutic effect. This article aims to review the pathophysiology of PTSD within multiple neurobiological systems and how these mechanisms are used as pharmacologic targets of treatment, as well as their potential for future targets of intervention.

RESUMO

Marijuana is becoming legal in an increasing number of states for both medical and recreational use. Considerable controversy exists regarding the public health impact of these changes. The evidence for the legitimate medical use of marijuana or cannabinoids is limited to a few indications, notably HIV/AIDS cachexia, nausea/vomiting related to chemotherapy, neuropathic pain, and spasticity in multiple sclerosis. Although cannabinoids show therapeutic promise in other areas, robust clinical evidence is still lacking. The relationship between legalization and prevalence is still unknown. Although states where marijuana use is legal have higher rates of use than nonlegal states, these higher rates were generally found even prior to legalization. As states continue to proceed with legalization for both medical and recreational use, certain public health issues have become increasingly relevant, including the effects of acute marijuana intoxication on driving abilities, unintentional ingestion of marijuana products by children, the relationship between marijuana and opioid use, and whether there will be an increase in health problems related to marijuana use, such as dependence/addiction, psychosis, and pulmonary disorders. In light of this rapidly shifting legal landscape, more research is urgently needed to better understand the impact of legalization on public health.

RESUMO

BACKGROUND: Medicinal marijuana has already been legalized in over 23 states with more considering legalization. Despite the trend toward legalization, to date, there has been no systematic review of the existing literature for the efficacy of medicinal marijuana for many of the conditions for which it is proposed to treat. This study seeks to understand the current literature regarding the use of medicinal marijuana in the treatment of posttraumatic stress disorder (PTSD). DATA SOURCES: PubMed and PsycINFO databases were searched until April 2014 for articles outlining outcomes of case files, control studies, and observational studies regarding the efficacy of medicinal marijuana in treating PTSD. Various combinations of the following search terms were used: marijuana, medicinal marijuana, cannabis, cannabinoid, PTSD, efficacy, trial, and neurobiology. STUDY SELECTION: Full text of each article was reviewed, and those directly addressing the question of efficacy of medicinal marijuana on PTSD symptomatology were included. Data were extracted from a total of 46 articles. RESULTS: Analysis revealed that most reports are correlational and observational in basis with a notable lack of randomized, controlled studies. Many of the published studies suggest a decrease in PTSD symptoms with marijuana use. Though the directionality of cannabis use and PTSD could not be fully differentiated at this time, there appears to also be a correlation between PTSD and problematic cannabis use. Despite this finding, there is a growing amount of neurobiological evidence and animal studies suggesting potential neurologically based reasons for the reported efficacy. CONCLUSIONS: Posttraumatic stress disorder is 1 of the approved conditions for medicinal marijuana in some states. While the literature to date is suggestive of a potential decrease in PTSD symptomatology with the use of medicinal marijuana, there is a notable lack of large-scale trials, making any final conclusions difficult to confirm at this time.

RESUMO

OBJECTIVE: To raise awareness about the growing trend of cocaine abuse in later years as an underdiagnosed, undertreated, and comorbid condition in older individuals. Three cases of cocaine use in patients over the age of 50 years in the Malcolm Randall Veterans Medical Center, Gainesville, Florida, within a 10-day span in 2013 are presented. DATA SOURCES: PubMed was searched using combinations of keywords, including cocaine, addiction, elderly, and aging, to find articles published between 1986 and 2013. STUDY SELECTION: In total, 37 articles were selected for inclusion on the basis of their relevance to the objective and importance to the representation of cocaine abuse, including international guidelines for addiction. DATA EXTRACTION: Each article was reviewed for eligibility. Final decisions were made following full-text review. RESULTS: Cocaine addiction remains a high-morbidity chronic-relapsing illness with few treatment options. A review of the literature shows that late-life cocaine use is sparsely recognized. Of particular interest are the clinical presentations in which a higher index for detection is warranted. The high rate of medical comorbidity associated with cocaine use, especially cerebrovascular deficits, presents special treatment and social challenges. CONCLUSIONS: As the number of older individuals admitted for substance use continues to climb, clinicians must adapt to the changing demographics by increasing screening, early detection, and treatment options for older persons.
