Trial Summary

What is the purpose of this trial?

This pilot study will investigate the safety, feasibility, tolerability, and preliminary efficacy of accelerated high-dose repetitive transcranial magnetic stimulation (rTMS) targeting the medial prefrontal cortex (mPFC) to address apathy symptoms in individuals with chronic stroke.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment MagVenture MagPro Transcranial Magnetic Stimulation (TMS) System for post-stroke apathy?

Research shows that repetitive transcranial magnetic stimulation (rTMS) can improve apathy in stroke patients, as seen in a study where patients receiving rTMS had significant improvements in apathy scores compared to those receiving a sham treatment. Additionally, rTMS has been effective in treating post-stroke depression, suggesting its potential benefits for related conditions like apathy. ^{1 2 3 4 5}

Is accelerated rTMS safe for humans?

Accelerated repetitive transcranial magnetic stimulation (rTMS) has been studied for various conditions and is generally considered safe, with very few side effects reported. The most serious risk is seizures, but these are rare and often linked to not following safety guidelines. Studies have shown that accelerated rTMS is well-tolerated in both healthy individuals and patients with conditions like depression and post-stroke depression. ^{5 6 7 8 9}

How does the treatment for post-stroke apathy using the MagVenture MagPro TMS System differ from other treatments?

The MagVenture MagPro TMS System uses repetitive transcranial magnetic stimulation (rTMS), which is a non-invasive treatment that applies magnetic fields to stimulate specific brain regions. This approach is unique because it targets areas like the dorsal anterior cingulate cortex and medial prefrontal cortex to improve apathy, a condition for which there are few effective treatments. Unlike medications, rTMS directly influences brain activity and has shown promise in improving symptoms of apathy and depression in stroke patients. ^{1 2 3 5 10}

Eligibility Criteria

This trial is for individuals over 40 who've had a stroke at least 6 months ago and are experiencing apathy. They must be able to do cognitive tests, have an intact cortex in the target area confirmed by imaging, and score high on specific apathy scales. Excluded are those with other major neurological issues, severe communication problems, psychotic disorders, recent suicidality or substance abuse, pregnancy, MRI or TMS contraindications like pacemakers or metal implants.

Inclusion Criteria

I can take part in mental health and thinking tests.

I am 40 years old or older.

You are showing signs of not caring about things.

Exclusion Criteria

You feel very uncomfortable in small spaces and can't have an MRI scan.

I do not have implants or devices that could be affected by MRI or TMS.

You have bleeding outside the brain.

Treatment Details

Interventions

• MagVenture MagPro Transcranial Magnetic Stimulation (TMS) System (Transcranial Magnetic Stimulation)

Trial Overview The study is testing whether a high-dose version of rTMS (a non-invasive brain stimulation technique) can reduce symptoms of apathy in people who have had a stroke. The treatment targets the medial prefrontal cortex and aims to see if it's safe and effective when given at an accelerated pace.

Participant Groups

Group I: Repetitive transcranial magnetic stimulation Experimental Treatment 1 Intervention

All participants will receive accelerated, high-dose repetitive transcranial magnetic stimulation (rTMS) at the medial prefrontal cortex (mPFC) delivered in runs of 600 pulses, twelve times per day, for three treatment days (contiguous or non-contiguous) within a seven-day period.

Repetitive transcranial magnetic stimulation (rTMS) has shown a positive impact on apathy in patients with Alzheimer's disease and some potential benefits in chronic stroke, suggesting it may be a feasible treatment option for these conditions.

The safety of rTMS was confirmed across various studies, but its efficacy varied significantly among different neurodegenerative conditions, with limited evidence of effectiveness in Parkinson's disease and mild traumatic brain injury.

In a pilot study involving 6 patients with post-stroke depression, an accelerated rTMS protocol significantly reduced depression scores (HAMD) from an average of 15.5 to 4.17, with effects lasting up to 3 months after treatment.

The study found that the accelerated rTMS treatment was safe, with no significant adverse events reported, suggesting it could be a viable alternative or adjunctive therapy for post-stroke depression.
