tTED Trial Summary

This trial will study the mechanisms and treatment of neuropsychiatric symptoms in Alzheimer's dementia (AD) with the use of transcranial magnetic stimulation (TMS) combined with electroencephalography (EEG). The investigators will also evaluate if transcranial direct current stimulation (tDCS) is effective to treat agitation dementia.

Who is the study for?
This trial is for individuals aged 50 or older with Alzheimer's dementia who experience agitation. They must have a stable dose of neuropsychiatric medication if they're taking any, and cannot be on certain drugs like anticonvulsants or benzodiazepines that interfere with the study. Participants need informed consent and a support person to attend appointments.Check my eligibility
What is being tested?
The study tests non-invasive brain stimulation methods (TMS-EEG and tDCS) to understand and treat agitation in Alzheimer's dementia. It aims to explore the underlying mechanisms of these symptoms using magnetic stimulation combined with EEG, as well as assess the effectiveness of tDCS treatment.See study design
What are the potential side effects?
Potential side effects from TMS may include discomfort at the stimulation site, headache, lightheadedness, or seizures (rare). tDCS might cause skin irritation under the electrode, tingling sensation during administration, fatigue or nausea.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Long Interval Cortical Inhibition (LICI), a TMS paradigm, will be used to assess the extent of cortical inhibition
Secondary outcome measures
Assess GABA and glutamate levels using Magnetic Resonance Spectroscopy (MRS)
Assess brain structure using Magnetic Resonance Imaging (MRI)

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Active tDCSExperimental Treatment1 Intervention
The direct current will be delivered at 2 mA intensity via rubber electrodes in saline- soaked sponges for 30 min per day for 2 weeks, 5 days/week. Inhibitory stimulation will be delivered to the frontal lobes.
Group II: sham tDCSPlacebo Group1 Intervention
Sham tDCS will use the same parameters except that the device will automatically turn off after a certain duration.
