Targeting pro-dopaminergic agonism to attenuate depression in patients displaying genetic/epigenetic predisposition to hypodopaminergia
Since 1990, substantial evidence from association studies has identified the D(2) dopamine receptor (DRD2) gene as a factor in the development of alcoholism [1][2][3][4]. The DRD2 gene has also been linked to other substance use disorders, including dependencies on cocaine, nicotine, and opioids, as well as obesity [5][6][7][8][9][10][11]. Dopamine in the brain, often referred to as the "stressrelief molecule," plays a central role in managing st…
Attention Deficits in Healthcare Workers with Non-Clinical Burnout
Burnout syndrome is characterized by exhaustion, cynicism, and reduced effectiveness. Workers with high burnout scores who continue their professional activities are identified as experiencing non-clinical burnout (NCB), which includes early stages where burnout symptoms (BNS) are present but not yet severe enough to necessitate work leave. This study aimed to investigate the impact of BNS on attention performance among healthcare workers (HCWs) …
Association between attention performance and the different dimensions of DSM-5 depression symptoms
The predominance of the somatic cluster was related to lower alertness, whereas the predominance of non-somatic cluster was associated with impulsivity/hyperactivity. This result may explain the difficulties associated with correctly classifying the item concentration difficulties. A brief attentional task can be used as an auxiliary tool to correctly identify the different dimensions of attention that are associated with different clusters of de…
Analysis of Attention Subdomains in Obstructive Sleep Apnea Patients
Background: Obstructive sleep apnea (OSA) is characterized by apnea-hypopnea during sleep. Overnight polysomnography (PSG) is usually used to detect the frequency of apneic and hypopneic events. Attention and executive deficits are commonly reported in OSA patients. Previous investigations suggested that cognitive impairments were dependent on attention deficits. However, attention is not a unitary domain and consists of different subdomains such…
DSM-5 Criteria and Depression Severity
Background: Depression diagnosis requires five or more symptoms (Diagnostic and Statistical Manual of Mental Disorders-DSM-5). One of them must be either Depressed mood or Anhedonia, named main criteria. Although the secondary symptoms can be divided into somatic and non-somatic clusters, the DSM-5 identify depression in all or none fashion. In contrast, depression severity is a continuous variable. Therefore, it is commonly assessed with scales …
Validity and reliability of a teacher's scale developed in Brazil for assessment of hyperactive
This study was designed to develop and assess the internal consistency and factor structure of a teacher's scale for the assessment of hyperactive/impulsive and inattentive behavior in a sample of 221 children from different cities in the State of Rio de Janeiro, Brazil. Forty-five teachers rated the children. The internal consistency of the scale was evaluated using Cronbach's alpha. An orthogonal varimax rotation that maximizes the variance of …
Eficácia Do Teste Computadorizado De Atenção Visual (Tca) E Do Mini Exame Do Estado Mental (Meem) Na Identificação De Portadores De Transtorno Cognitivo Leve
Com o envelhecimento populacional as doenças da terceira idade têm recebido maior atenção. A Doença de Alzheimer é a forma mais comum de demência e o Transtorno Cognitivo Leve (TCL), período de transição entre as mudanças cognitivas do envelhecimento normal e o completo desenvolvimento das características clínicas de demência, tem sido amplamente estudado. O objetivo do estudo foi avaliar 2 testes neuropsicológicos comparando sua acurácia diagnós…
