Depression affects millions of people in the United States. However, it is often overlooked in older adults. Geriatric depression refers to depression that occurs in people aged 65 and older. It is a serious mental health condition that can worsen if left untreated.
Many elderly individuals face medical illnesses, cognitive impairments, and social isolation. These factors can increase the risk of developing depression. Unfortunately, depression in the elderly is frequently misdiagnosed or ignored.
Traditional treatments for depression, like medication, may not be effective for older adults. This is where Transcranial Magnetic Stimulation (TMS) therapy offers hope.

Understanding TMS Therapy for the Elderly
Transcranial Magnetic Stimulation (TMS) is a non-invasive brain stimulation technique. It uses magnetic fields to stimulate specific areas of the brain. This stimulation helps improve mood and alleviate symptoms of depression. Repetitive Transcranial Magnetic Stimulation (rTMS) involves delivering these magnetic pulses repeatedly over several sessions.
TMS is an FDA-approved treatment primarily used for:
- Treatment-resistant depression
- Depression with suicidal behavior
- Anxious depression
- Obsessive-compulsive disorder (OCD)
The procedure involves placing a coil or cap-like device on the patient’s head, which emits electromagnetic pulses to specific brain regions. Each session typically lasts about 20 minutes and is conducted in an outpatient setting. Notably, TMS does not require anesthesia and has minimal side effects, making it suitable for older adults who may be sensitive to medications.
For elderly individuals with major depressive disorders, TMS therapy offers a drug-free treatment option. Many older adults experience side effects from antidepressant treatment. TMS provides a safer alternative without systemic side effects. Additionally, seniors tolerate this treatment option, even for those with cognitive decline or physical illnesses.
What is Geriatric Depression?
Geriatric depression, also known as late-life depression, is a significant mental health condition that affects older adults, typically those aged 60 and above. The prevalence of geriatric depression is notable, with community rates estimated at approximately 11.2% for combined major and minor depressive symptoms.
Symptoms of Geriatric Depression
It can manifest as persistent low mood, and loss of interest or pleasure in activities. Late-life depression may include more physical symptoms like fatigue, weight loss, or chronic pain. Cognitive impairments, such as memory loss, are also common. Other symptoms include:
- Changes in appetite or weight
- Changes in sleep pattern (insomnia or hypersomnia)
- Irritability and difficulty concentrating
- Mood disorders
- Physical complaints like headaches or stomachaches
- Thoughts of death or suicide.
Older adults may not always express typical depressive symptoms. Instead, they may exhibit more somatic complaints or impaired cognitive functions.
Causes and Risk Factors
Several factors contribute to depression on older adults, including:
- Chronic medical illnesses like heart disease or Alzheimer’s disease
- Loss of loved ones or significant life changes
- Social isolation or lack of support networks
- Retirement and financial stress
These factors make the treatment of depression in the elderly more complex. Additionally, older adults may experience cognitive decline, which can impact their ability to recognize and seek help for depression.
Impact on Quality of Life
The consequences of untreated geriatric depression can be severe, leading to:
- Increased morbidity and mortality
- Declines in physical health
- Poor compliance with medical treatment
- Higher rates of disability
Moreover, depression in the elderly is frequently underdiagnosed and undertreated due to overlapping symptoms with other age-related conditions such as dementia.
TMS For Geriatric Depression
TMS therapy targets specific areas of the brain responsible for mood regulation. During a session, a magnetic coil is placed on the patient’s head. The coil sends magnetic pulses to the brain’s prefrontal cortex, which is associated with mood control.
Unlike electroconvulsive therapy (ECT), TMS therapy is non-invasive and painless. It does not require anesthesia and has minimal side effects. This makes it ideal for older adults who may not tolerate more invasive procedures.
For those with major depressive disorders that do not respond to medication, TMS for geriatric depression offers a new pathway to recovery.
Considerations for Alzheimer’s Disease
While TMS is primarily approved for depression, its off-label use for conditions like Alzheimer’s disease is permitted if both patient and physician understand the associated risks and benefits. This flexibility allows healthcare providers to tailor treatments to individual patient needs, particularly in geriatric care
Benefits of TMS for Older Adults?
There are several benefits of TMS for older adults compared to traditional treatments for depression:
- Non-Invasive and Drug-Free: TMS is a non-invasive brain stimulation method. It does not require medications, which can be problematic for older adults with physical illnesses or cognitive impairments.
- Minimal Side Effects: Unlike medications, TMS therapy has minimal side effects. Common side effects are mild and may include scalp discomfort or headache. These symptoms typically resolve quickly.
- Improves Cognitive Function: Studies show that TMS therapy may help improve cognitive function in older adults. This is especially important for those experiencing cognitive decline or early stages of Alzheimer’s disease.
- Suitable for Medication-Resistant Depression: Many elderly individuals are resistant to antidepressant treatment. TMS therapy offers an effective alternative for those who have not found relief with medication.
- Durable Effects: The benefits of TMS can last for months after treatment, providing sustained relief from symptoms without the need for continuous medication
Success Rates of TMS for Elderly Depression
Transcranial Magnetic Stimulation (TMS) has shown promising success rates in treating depression among the elderly, particularly those aged 65 and older. TMS is 2-3 times more effective in resolving geriatric depression than conventional antidepressant medications and talk therapy.
A recent study indicated that 54% of patients treated with repetitive TMS (rTMS) exhibited a significant clinical response, defined as at least a 50% improvement in mood symptoms. This response rate aligns with findings from other studies that report remission rates stabilizing at 60-70% after extended treatment.
TMS therapy represents a highly effective and well-tolerated treatment option for geriatric depression, with success rates comparable to or exceeding those of younger populations. Its ability to provide rapid symptom relief and improve overall cognitive function makes it a valuable tool in managing mental health in the elderly.
How Quickly Can Elderly Patients See Improvements with TMS?
Elderly patients undergoing Transcranial Magnetic Stimulation (TMS) can typically start to see improvements in their depressive symptoms relatively quickly.
Timeline for Improvements with TMS
- Initial Improvements: Many patients report experiencing improvements within the first week of treatment. This early response can be particularly encouraging for those suffering from severe depression.
- Optimal Results: While some may notice benefits sooner, the best results are generally observed after about four to six weeks of consistent treatment. The standard treatment regimen usually involves five sessions per week over a six-week period, totaling around 30 sessions.
- Variability in Response: Individual responses to TMS can vary significantly. Factors such as the severity of depression, individual brain chemistry, and adherence to the treatment schedule can influence how quickly and effectively a patient responds.
- Long-Term Benefits: TMS has shown durable effects for those who respond well, with many patients maintaining improvements for months after completing their initial treatment course. However, some may require maintenance sessions to sustain these benefits over time.
Who is a Good Candidate for TMS Therapy?
Not all elderly individuals are suitable candidates for TMS therapy. However, it is an excellent option for those who:
- Have medication-resistant depression
- Experience cognitive impairments but are still able to participate in therapy
- Suffer from late-life depression with minimal response to other treatments
Patients with severe medical illnesses or implanted devices may need additional evaluation to determine if TMS therapy is safe for them.
Potential Challenges of TMS in Older Adults
While TMS therapy offers many benefits, there are challenges to consider:
- Cost and Insurance Coverage: TMS therapy can be expensive. However, many insurance providers in the United States now cover TMS treatments for depression.
- Physical Limitations: Some elderly people may find it uncomfortable to sit for extended periods. It is essential to discuss any physical illnesses or limitations with the care provider before starting TMS therapy.
- Access to TMS Clinics: Access to TMS therapy may be limited in rural areas. However, more TMS clinics are opening across the United States as demand increases.
