Hypnosis and Attention in Patients With a Neurological Disease (Stroke, Traumatic Brain Injury and Multiple Sclerosis)

Hypnosis and Attention in Patients With a Neurological Disease

This feasibility study investigates the potential of hypnosis as a complementary therapy for improving attentional deficits and reducing fatigue in patients with neurological conditions such as stroke, traumatic brain injury (TBI), and multiple sclerosis (MS). These patients often experience reduced spontaneous visual exploration and impaired functional independence despite current rehabilitation approaches. By integrating hypnosis with standard care and using EEG to monitor brain activity during hypnosis and sham-hypnosis sessions, this trial aims to evaluate the feasibility, acceptability, and preliminary efficacy of hypnosis in enhancing attention and reducing fatigue.

Neurological conditions such as stroke, traumatic brain injury (TBI), and multiple sclerosis (MS) frequently cause significant impairments in attentional abilities. Commonly accompanying symptoms include visual spatial neglect (VSN) and fatigue syndrome, which exacerbate attentional deficits. These impairments manifest notably as a reduction in spontaneous or free visual exploration (FVE), limiting patients' ability to actively scan and engage with their environment. This diminished visual exploration negatively impacts their capacity to navigate daily surroundings, compromising functional independence and overall quality of life.

Current therapeutic approaches include cognitive rehabilitation, visual exploration training, and non-invasive brain stimulation to promote neuroplasticity and functional recovery. Additionally, management of fatigue focuses on energy regulation strategies in everyday life. Despite these interventions, many patients continue to experience persistent attentional deficits and fatigue after rehabilitation, limiting their ability to perform daily activities and return to previous roles.

Hypnosis is emerging as a promising adjunct therapy in neurological rehabilitation. Widely used in medical fields such as pain management and mental health, hypnosis leverages the brain's ability to enter a state of focused attention and heightened cognitive receptivity, facilitating symptom relief and treatment enhancement without pharmacological side effects. Preliminary evidence suggests hypnosis can improve attentional control and reduce fatigue in neurological populations.

However, research on hypnosis in neurology remains limited, with a need for larger, rigorously controlled studies to confirm its efficacy and understand underlying mechanisms. This feasibility study aims to assess the practicality and acceptability of using hypnosis to treat attentional deficits and fatigue in patients with stroke, TBI, and MS, while also evaluating preliminary efficacy.

A key aspect of this study involves recording electroencephalography (EEG) during both hypnosis and sham-hypnosis sessions. EEG data will provide insight into neural correlates of attentional processing and determine whether hypnosis induces measurable changes in brain activity relative to sham conditions.
