Lyme Disease Suicide Risk: An Underrecognized Patient Group
Lyme disease suicide risk remains underrecognized despite growing evidence linking Lyme-associated diseases with psychiatric symptoms, including depression and suicidality.
Bransfield’s colleagues from Howard University, Rush University Medical Center, and the University of North Dakota agree with his assessment, stating, “We would like to applaud the author for conducting such an important study by performing a comprehensive assessment of suicide and its association with Lyme-associated diseases (LADs).” [2]

In their article “Suicidal and homicidal tendencies after Lyme disease: an ignored problem,” these psychiatrists listed published case reports supporting Bransfield’s concerns:
- “A 44-year-old male without any past psychiatric history presented with a third unsuccessful suicide attempt and was later diagnosed as having Borrelia infection.” One month of intravenous ceftriaxone resulted in improvement in mental status and resolution of suicidal ideation. [3]
- “Patients with Lyme borreliosis can experience psychiatric issues during both acute and late phases of the disease, most commonly depression. In some cases, it progresses to severity and suicidality … but may also be unpredictable.” [4]
- “Two patients were diagnosed with Lyme disease and appropriate treatment was offered. A few months later, both developed severe depression with suicidal threats, and one attempted suicide. Evidence of persistent Lyme borreliosis was found in both cases.” [5]
In one highlighted case, patient A was suicidal, violent, and physically assaultive. Patient B, followed over 30 years, “was highly suicidal, had intrusive violent images, and impulses which were eliminated with treatment,” explains Bransfield. [2] Both patients improved with antibiotic and psychotropic treatment, which “was clearly life saving.”
Why Lyme Disease Suicide Risk May Be Overlooked
Psychiatric symptoms in Lyme disease can be difficult to recognize and may be misattributed to primary psychiatric conditions rather than underlying infection or immune-mediated mechanisms.
Depression, anxiety, cognitive impairment, and behavioral changes may emerge during both early and late stages of Lyme disease, complicating diagnosis and delaying appropriate treatment.
These challenges contribute to underrecognition of Lyme disease suicide risk in clinical practice.
Estimated Impact of Lyme Disease Suicide Risk
An estimated 1,200 suicides occur each year in the United States related to Lyme disease and associated conditions, according to Bransfield.
This estimate highlights the potential scale of psychiatric complications in tick-borne illness and underscores the need for improved awareness, screening, and treatment strategies.
Key Clinical Questions
Bransfield raises several important unanswered questions:
- Why do only some patients with Lyme-associated diseases develop chronic symptoms, psychiatric symptoms, or suicidality?
- What are the underlying pathophysiologic mechanisms driving these psychiatric manifestations?
- What diagnostic and treatment approaches are most effective?
- How many patients are affected, and to what extent?
Clinical Perspective
The association between Lyme disease and psychiatric symptoms—including suicidality—requires careful clinical attention.
Patients presenting with new-onset depression, behavioral changes, or suicidal ideation—particularly with a history of tick exposure—should prompt consideration of Lyme disease and associated infections.
At the same time, clinicians must evaluate for persistent infection, immune dysfunction, and co-infections when symptoms are severe or refractory.
Clinical Takeaway
Lyme disease suicide risk is an underrecognized but serious complication of Lyme-associated diseases.
Improved awareness, early recognition, and comprehensive treatment approaches may help reduce psychiatric morbidity and potentially life-threatening outcomes in affected patients.

Crisis Support and Safety
If you or someone you know is experiencing suicidal thoughts, it is important to seek help immediately.
- Call or text 988 — the Suicide & Crisis Lifeline (U.S.)
- Call 911 or go to the nearest emergency room if there is immediate danger
- Reach out to a trusted family member, friend, or healthcare professional
For patients with Lyme disease, psychiatric symptoms may have underlying medical contributors, including infection, inflammation, or co-infections. A comprehensive medical and psychiatric evaluation is recommended.

Thank you for speaking about Lyme Suicide. It is my mission to raise awareness and prevent this from happening. https://www.eventbrite.com/e/conference-on-neurological-tick-infections-mental-illness-suicide-prevention-tickets-35080930006?aff=es2
You have an outstanding faculty. The goal is great “This educational summit is a 1-1/2 day program for physicians and nurses on the diagnosis and treatment of neurological tick infections ( i.e.: Borellia Burdorferi, Bartonella etc.) which lead to cognitive impairments, mental illness and ideations of suicide/violence.”
This is very real. It haplened to me. I attempted suicide three times and almost succeeded twice. Doctors misdiagnosed and mistreated me. It was the most painful and scariest part of my life. I estimate I went undiagnosed for at least 7 years. I was losing my mind and my life and knew I was in a struggle for my life. I am one of the lucky who remember the tick bite and how things went downhill after it. I found a Lyme doctor and within a couple of month the depression was gone after taking antibiotics. It has taken longer for other symptoms to slowly get better but having the depression clear was the first step in having my life return to what it once was. Anyone older who is depressed and has never had depression before should be evaluated for a medical problem thag may be the cause of the depression. My depression was treatment resistant. That should have been a sign to the doctors.
If someone has Chronic Lyme disease and they begin to experience suicidal thought, should they go to their Lyme doctor or a psychiatrist for help?
It remains important to seek immediate help if you have suicidal thoughts. It is important to use of 911 or the emergency room if your doctor is not available. It also is important to consider an assessment for a tick borne illness as part of any evaluation.
I wish this article came out sooner. 5/1/17, my husband who we called Tommy tick, or Tommy tick magnet shot himself. He had been treated for Lyme’s disease. He was a hunter and woodsman. He loved the outdoors, but always managed to find a tick on him. After a beautiful trip to Aruba, we came home Saturday, and on Sunday his behavior was delusional. I did not know what to do, or what was wrong. That night, he shot himself. I truly believe his suicide was tick disease related. Please bring this to the forefront so that there is enough awareness.
Sorry to hear your loss.
My family adopted a stray cat when I was small & I got scratched then developed cat scratch fever from it. After three neurosurgeries for bartonella cysts, I attempted suicide twice. This was decades ago. It was a very dark time bc I didn’t have a diagnosis yet and my family didn’t understand the severity of suffering or how to offer any validation or support. As I was in my early 30s with few answers there was a lot of pressure to settle down marry and have kids but each time I got close the symptoms would push people away. Had numerous hospitalizations with no answers. My family came to think of me as a failure when I bounced from relationship to relationship unable to get traction with health family or career. Even though I worked my way up to top positions in journalism in Washington & Hollywood the disease always caused me to crash again and to lose everything. After surgeries left me with neuropathy the pain led me to seek pain meds or mmj. My family then labeled me an addict. This illness takes everything. Yet I wake up every day with hope to heal & be of service. It keeps me going. Sadly it’s now decades later and my family still feels terribly drained by this horrible illness (Lyme) & the poor politics and sad lack of support or awareness. StIll we press on in faith. Thanks for all you do to shed light Dr. Cameron.
Too late for me – I developed horrendous constant visual disturbances accompanied by an inexplicable feeling of horror and absolute dread for 2 years after contracting lyme disease. Even though I was one of the lucky few who received an NHS diagnosis, doctors still insisted my symptoms were psychosomatic and were on the verge of sectioning me under the mental health act. The thought of being institutionalised while suffering these horrendous symptoms and the accompanying neuropsychiatric anxiety and dread from my inflamed, infected brain pushed me over the edge and I made a last minute, panic-driven suicide attempt by jumping off a bridge. Amonth of ceftriaxone while I was in hospital with numerous broken bones restored my sanity, although I still battle with other aspects of the disease. The repercussions of feel as if they have destroyed my sense of self, well-being and body image to the point that my PTSD and distress is so great I cannot even try to treat the Lyme properly. I have had 6 years of constant trauma and despair since with no end in sight. I still cannot believe that a disease that was discovered as far back as the 60s has been so neglected, so weirdly politicised and still so poorly handled by medical authorities around the world. The amount ruined lives is staggering.
