Doctors agree Lyme disease patients at-risk for suicide are under-recognized group

There are many documented cases of patients with Lyme disease suffering from suicidal or homicidal tendencies.  In the journal Neuropsychiatric Disease and Treatment, psychiatrist Robert Bransfield, MD, expresses his concern for this under-recognized patient population.  “Suicidal and homicidal tendencies after Lyme disease are clearly an ignored problem that deserves greater attention.” [1]


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]

Suicidal and homicidal tendencies in Lyme disease patients is an ignored problem.

In their article “Suicidal and homicidal tendencies after Lyme disease: an ignored problem,” these three 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 medical therapy with intravenous ceftriaxone resulted in improvements in his 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 common being depression. In some cases, it slowly progresses to severity and suicidality … but in some cases, it is unpredictable.” [4]

• “[Two] patients were diagnosed with Lyme disease and appropriate treatment was offered. A few months after the treatment, both patients developed severe depression along with suicidal threats and an attempt by one patient. Evidence of persistent Lyme borreliosis was found in both cases.” [5]

In the third highlighted case, patient A was also suicidal, violent, and physically assaultive to her son. Patient B, who was followed over a span of 30 years, “was highly suicidal, had horrific intrusive images of killing others, and had violent impulses which were eliminated with treatment,” explains Bransfield. [2] Both patients recovered with antibiotic and psychotropic treatment, which “was clearly life saving.”

An estimated 1200 suicides take place each year in the US due to Lyme and associated diseases. Click To Tweet

Bransfield raises several questions: [6]

  1. Why do only some patients with Lyme-associated diseases develop chronic symptoms, psychiatric symptoms, different types of psychiatric symptoms, suicidality, or homicidality?
  2. What is the exact pathophysiology and what are the most effective diagnostic and treatment approaches?
  3. How many patients are actually impacted by these conditions and to what extent?

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.… Read more »

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… Read more »


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?


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… Read more »
