Understanding the experiences of ketogenic metabolic therapy for people living with varying levels of depressive symptoms: a thematic analysis.

Background: Evidence suggests that a ketogenic diet (KD) may help to alleviate psychiatric symptoms, including depression and anxiety. Positive changes have been reported such as improvements in cognition, concentration, and sleep, a reduction in hunger, and an increase in well-being, energy, confidence, and resilience. This research aims to understand the impact of a non-calorie-restricted KD on depression and aspects of psychological well-being in those with varying degrees of depressive symptoms.

Alcohol and drug use among bartenders: An at risk population?

Introduction: The current study explored the prevalence of hazardous alcohol and drug consumption within bartenders and the impact of working more than 40 h a week on levels of alcohol and drug use.

Methods: Three hundred and ninety bartenders (247 females), recruited via social media, took part in a cross-sectional online survey. The study recorded units of alcohol and hours worked per week among participants.

Neurophysiological markers of prospective memory and working memory in typical ageing and mild cognitive impairment.

Objective: Prospective memory (PM) -the memory of delayed intentions- is impacted by age-related cognitive decline. The current event-related potential study investigates neural mechanisms underpinning typical and atypical (Mild Cognitive Impairment, MCI) age-related decline in PM.

Methods: Young adults (YA, n = 30, age = 24.

Reasoning deficits among illicit drug users are associated with aspects of cannabis use.

Deficits in deductive reasoning have been observed among ecstasy/polydrug users. The present study seeks to investigate dose-related effects of specific drugs and whether these vary with the cognitive demands of the task. One hundred and five participants (mean age 21.

Temporal and visual source memory deficits among ecstasy/polydrug users.

Objectives: We wished to investigate whether source memory judgements are adversely affected by recreational illicit drug use.

Method: Sixty-two ecstasy/polydrug users and 75 non ecstasy users completed a source memory task, in which they tried to determine whether or not a word had been previously presented and if so, attempted to recall the format, location and temporal position in which the word had occurred.

Results: While not differing in terms of the number of hits and false positive responses, ecstasy/polydrug users adopted a more liberal decision criterion when judging if a word had been presented previously.

Prospective memory deficits in illicit polydrug users are associated with the average long-term typical dose of ecstasy typically consumed in a single session.

Rationale: Neuroimaging evidence suggests that ecstasy-related reductions in SERT densities relate more closely to the number of tablets typically consumed per session rather than estimated total lifetime use. To better understand the basis of drug related deficits in prospective memory (p.m.

Self-reports of executive dysfunction in current ecstasy/polydrug Users.

Objectives/background: Ecstasy/polydrug users have exhibited deficits in executive functioning in laboratory tests. We sought to extend these findings by investigating the extent to which ecstasy/polydrug users manifest executive deficits in everyday life.

Methods: Forty-two current ecstasy/polydrug users, 18 previous (abstinent for at least 6 months) ecstasy/polydrug users, and 50 non-users of ecstasy (including both non-users of any illicit drug and some cannabis-only users) completed the self-report Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) measure.

Visuospatial working memory impairment in current and previous ecstasy/polydrug users.

Objective: Previous research suggests that ecstasy users are impaired in processing visuospatial information. However, for the most part, the deficits observed appear to involve the recall and recognition of complex visual and geometric patterns. The present research sought to determine whether ecstasy use was associated with deficits in serial spatial recall and visuospatial working memory (VSWM).

Prospective memory functioning among ecstasy/polydrug users: evidence from the Cambridge Prospective Memory Test (CAMPROMPT).

Rationale: Prospective memory (PM) deficits in recreational drug users have been documented in recent years. However, the assessment of PM has largely been restricted to self-reported measures that fail to capture the distinction between event-based and time-based PM. The aim of the present study is to address this limitation.

Modelling the adverse effects associated with ecstasy use.

Aims: Ecstasy, the street name for 3,4-meththylenedioxymethamphetamine, has been associated with a range of psychiatric symptoms and impaired psychological health in both problem and recreational users. The purpose of the present paper is to determine how these impairments are related to the history of polydrug use, and the conditions under which individuals ingest ecstasy.

Design: Associations between the variables of interest were investigated utilizing negative binomial regression.

Everyday and prospective memory deficits in ecstasy/polydrug users.

The impact of ecstasy/polydrug use on real-world memory (i.e. everyday memory, cognitive failures and prospective memory [PM]) was investigated in a sample of 42 ecstasy/polydrug users and 31 non-ecstasy users.
