Delirium Treatment With Transcranial Electrical Stimulation
Sponsor: A.J.C. Slooter
Summary
The goal of this clinical trial is to investigate the effectiveness of standardized and personalized transcranial alternating current stimulation (tACS) in patients with delirium. To investigate this, will perform a double-blind, randomized, sham-controlled, multicenter trial. To test the safety and feasibility of tACS in delirious patients, the first 30 patients will be randomized to receive either active or sham tACS treatment in a 1:1 ratio through a pilot study. For the main phase of the study, patients will be randomized, resulting in an overall 1:1:1 allocation to standardized tACS, personalized tACS or sham treatment. Electroencephalogram (EEG) will be measured directly before and directly after the first stimulation session to assess whether tACS can reduce relative delta power. tACS or sham treatment will be given once daily for a maximum of 14 days, or until resolution of delirium or discharge (whichever comes first). During the treatment phase, presence and severity of delirium will be assessed daily. After the treatment phase, an additional EEG will be measured. Cognitive status will be assessed three months after the initial tACS session.

transcranial alternating current stimulation (tACS)
tACS is a non-invasive brain stimulation technique which involves the application of a low intensity electric current between two or more surface electrodes. tACS uses stimulation with a current alternating at a specific frequency that can entrain endogenous neuronal oscillations by inducing neural synchronization. The administration of tACS is proposed to phase-lock large populations of neurons in the superficial layers of the cerebral cortex causing neural synchronization in the corresponding frequency, thereby altering connectivity. tACS will be delivered via a transcranial electrical stimulation (tES) device (Nurostym tES, Brainbox Ltd, United Kingdom). This device has been CE-marked for use as a medical device for the treatment of mental and neurological disorders.
Sham transcranial alternating current stimulation (tACS)
Sham-tACS is a form of non-effective stimulation which can mimic the subjective sensation of active tACS treatment. During sham-tACS, the device will ramp up to 2.0 mA peak-to-peak intensity for 30 seconds, stimulate for 60 seconds and ramp down for 30 seconds, which mimics the sensation of actual tACS stimulation and improves blinding.The sham-tACS will be delivered via a transcranial electrical stimulation (tES) device (Nurostym tES, Brainbox Ltd, United Kingdom). This device has been CE-marked for use as a medical device for the treatment of mental and neurological disorders.
