Learning by observing: a systematic exploration of modulatory factors and the impact of observationally induced placebo and nocebo effects on treatment outcomes

Frontiers in Psychology
Introduction Observational learning (OL) refers to learning through observing other people’s behavior. OL has been suggested as an effective and simple tool to evoke treatment expectations and corresponding placebo and nocebo effects.

Time to prerandomization seizure count design sufficiently assessed the safety and tolerability of perampanel for the treatment of focal seizures

Epilepsia, EarlyView.
Abstract Objective In traditionally designed randomized clinical trials of antiseizure medications, participants take a blinded treatment for a prespecified number of weeks, irrespective of continued seizures. The alternative design time to prerandomization monthly seizure count (T‐PSC) allows participants to end the blinded treatment after an ...

No Reason to Feel Sick? Nocebo Responses in the Placebo Arms of Experimental Endotoxemia Studies

Frontiers in Psychiatry, 2019
Adverse side effects are reported by a large proportion of patients undergoing medical treatment in clinical practice or clinical trials. Nocebo effects, induced by negative treatment expectancies, can contribute to negative patient-reported outcomes but

A comparison of placebo and nocebo effects on objective and subjective postural stability: a double-edged sword?

Frontiers in Human Neuroscience, 2022
Background: Positive expectations (i.e., placebo effect) can improve postural control during quiet standing. This raises an important question: if postural control is susceptible to positive expectations, is it possible to elicit the opposite, a decline ...

Learning from missteps: Potential of transcranial electrical stimulation in neuropsychological rehabilitation

Journal of Neuropsychology, EarlyView.
Abstract Transcranial electrical stimulation (tES) holds promise for neuropsychological rehabilitation by leveraging the brain's inherent plasticity to enhance cognitive and motor functions. However, early results have been variable due to oversimplified approaches.

Potential placebo bias in current trials of delirium prevention: a network meta‐analysis of 86 randomized controlled trials

Psychiatry and Clinical Neurosciences, EarlyView.
Aim Numerous network meta‐analyses (NMAs) have reported inconsistent findings on the efficacy of various pharmacologic treatments for delirium prevention in high‐risk patients. A potential confounder was the study design—using a placebo control or standard‐of‐care (SoC) control. We reexamined the incident delirium between SoC plus placebo and SoC alone
