Effects of the Acute and Chronic Administration of Cannabidiol on Cognition in Humans and Animals: A Systematic Review.

The effects of cannabidiol (CBD) on cognition has been investigated in recent years to determine the therapeutic potential of this cannabinoid for a broad gamut of medical conditions, including neuropsychiatric disorders. The aim of the present study was to perform a systematic review of studies that analyzed the effects of the acute and chronic administration of CBD on cognition in humans and animals both to assess the cognitive safety of CBD and to determine a beneficial potential of CBD on cognition. The PubMed, Web of Science, PsycINFO, and Scopus databases were searched in December of 2022 for relevant articles using the following combinations of keywords: ("cannabidiol" OR "CBD") AND ("cognition" OR "processing cognitive" OR "memory" OR "language" OR "attention" OR "executive function" OR "social cognition" OR "perceptual motor ability" OR "processing speed").

Association between falls and cognitive performance among community-dwelling older people: a cross-sectional study.

Background: Falls among older people have a negative impact on health and therefore constitute a public health problem. Cognitive decline can also accompany the aging process, and both conditions lead to significant increases in morbidity and mortality in this population.

Objective: To analyze the cognitive performance of older people, classified as non-fallers, sporadic fallers and recurrent fallers, and investigate the relationship between falls and cognition.

Relationship of burden with depressive symptoms, mental disorders and older adults' functional dependence: A study with paid and unpaid caregivers in Brazil.

The objective of this study was to identify the relationship of burden with depressive symptoms, mental disorders and older adults' functional dependence in paid and unpaid caregivers. This is a quantitative and cross-sectional study, carried out in the inland of the state of São Paulo with 111 caregivers, 60 of whom were unpaid and 51 were paid. The caregivers answered a questionnaire for the assessment of sociodemographic and care characteristics, the Zarit Burden Inventory (ZBI), the Patient Health Questionnaire (PHQ-9), the Self-Report Questionnaire (SRQ-20), and the Functional Assessment Questionnaire (FAQ).

ADAM10: Biomarker of mild cognitive impairment but not of cognitive frailty.

Mild cognitive impairment (MCI) associated with physical frailty gave rise to the new concept of cognitive frailty. Previous studies have suggested that MCI may represent a condition that precedes Alzheimer's disease (AD), in view of its higher conversion rate to dementia, when compared with the conversion rate of cognitively healthy older adults. Therefore, and considering that MCI represents a reversible condition, the identification of biomarkers for this condition is imperative to early diagnosis.

Are facial emotion recognition tasks adequate for assessing social cognition in older people? A review of the literature.

Objective: Facial emotion recognition (FER) is a component of social cognition and important to interpersonal relations. Therefore, tasks have been developed to assess this skill in different population. Regarding older people, even healthy individuals have a poorer performance compared to rate of correct answers commonly used to assess such tasks.

Frailty and cognitive decline.

Effects of acute cannabidiol administration on anxiety and tremors induced by a Simulated Public Speaking Test in patients with Parkinson's disease.

Background: Cannabidiol (CBD) is one of the main components of and has anxiolytic properties, but no study has been conducted to evaluate the effects of CBD on anxiety signs and symptoms in patients with Parkinson's disease (PD). This study aimed to evaluate the impacts of acute CBD administration at a dose of 300 mg on anxiety measures and tremors induced by a Simulated Public Speaking Test (SPST) in individuals with PD.

Methods: A randomised, double-blinded, placebo-controlled, crossover clinical trial was conducted.
