简要总结
This trial aims at testing a new intensive, personalized functional targeting, transcranial magnetic stimulation technique for elderly patients (aged ≥ 65 years) suffering from a current treatment resistant depressive episode to at least one antidepressant, and suffering from significant secondary cognitive impairment.
The intervention will be based on an accelerated neuromodulation technique using intermittent theta bursts (aiTBS) guided by a personalised funcitonal target within the left dorsolateral prefrontal cortex (DLPFC), using the SAINT® technology, which was recently cleared by the FDA.
详细描述
Depression in older adults is often associated with cognitive impairment. Executive dysfunction exposes patients to poor response to antidepressants, increased risk of relapse and suicide, and greater disability. Depression doubles the risk of developing dementia in later life.
Late-onset depression is considered more difficult to treat due to low tolerance to standard antidepressant treatments, which prevents dose optimisation. Late-onset depression is considered more difficult to treat due to poor tolerance to standard antidepressant treatments, which prevents dose optimisation.
Furthermore, antidepressants are not optimal for improving cognitive function. Thus, antidepressant therapies are limited in terms of efficacy or tolerance, leading to persistent depressive symptoms and cognitive deficits that impact daily functioning, quality of life, and even independence.
Transcranial magnetic stimulation, a focused non-pharmacological antidepressant therapy, is a promising alternative. Several meta-analyses have demonstrated its efficacy as an antidepressant treatment and its potential for treating mild cognitive impairment. However, these studies have encountered certain limitations, such as small sample sizes and heterogeneity. Recently, a randomised controlled trial testing an accelerated form of intermittent theta burst stimulation (aiTBS) in adults with treatment-resistant depression demonstrated a high remission rate of approximately 80% (with effect sizes ranging from [1.4-1.8]). This technique has a good tolerance profile.
Overall, aiTBS treatment has several potentially beneficial aspects for depression in older adults: efficacy, rapid onset of action, and good tolerability. Such a technique could prevent the negative impact of depression and cognitive impairment on the quality of life and independence of older adults with depression.

- •Current moderate or severe substance use disorder (according to DSM-5 criteria) or demonstrating signs of acute substance withdrawal.
- •Any history of ECT (greater than 8 sessions) without meeting response criteria.
- •No recent (during the current depressive episode) or concurrent use of a rapid acting antidepressant agent (i.e., ketamine or a course of ECT).
- •History of significant neurologic disease, including Parkinson's or Huntington's disease, brain tumor, unexpected seizure/epilepsy disorder, subdural hematoma, multiple sclerosis, or history of significant head trauma (having caused a coma and/or requiring specific hospital care, and/or with abnormal brain imaging).
