A 57-year-old man with a severe brain injury developed a severe psychotic disorder 19 years later, apparently triggered by heavy use of psychedelic substances including cannabis, salvia divinorum, ketamine, LSD, cocaine, and DMT. The psychosis persisted even when he was not intoxicated and was marked by apathy, lack of concern, and abulia. The case suggests that heavy psychedelic substance misuse may potentiate a transition to psychosis in individuals with prior brain injury. The authors note that substance misuse has traditionally been an exclusion criterion for studying psychosis in this patient group and argue it should be investigated as a risk factor.

Robot-assisted gait training (RAGT) may help improve physical recovery and arousal in people with severe acquired brain injury who have impaired consciousness or cognitive functioning, but the evidence is limited. A scoping review of seven studies involving 162 participants found that RAGT was used mainly to support physical recovery, stimulate arousal, and ensure safety during early mobilization. Twenty-six different outcome measures were reported, indicating a lack of standardization. The review identifies a research gap: the rationales for using RAGT in this population need further investigation, and standardized outcome measures must be established. While RAGT shows potential for improving functional recovery and consciousness, future studies must address safety and feasibility while navigating ethical challenges.

An online self-study Mindfulness-Based Stress Reduction (MBSR) program was tested for people with mental fatigue after an acquired brain injury. Sixty participants were randomly assigned to the online MBSR course or a waitlist control group. Sixteen completed the MBSR program. No significant difference between groups was found overall, but the MBSR group showed significant reductions in mental fatigue, depression, and anxiety with large-to-medium effect sizes. The control group showed no significant changes. The online MBSR program can be feasible for those with less severe mental fatigue and emotional symptoms, while others may need a program adapted to their needs.
