Lyme Disease and Other Infections

Lyme Disease and Other Infections

Lyme disease (Borrelia burgdorferi) is a bacterial infection caused by the bite of an infected black-legged tick, also known as a deer tick. This disease has been vastly under-diagnosed in the U.S. due to inadequate testing methods and a general lack of acknowledgment by the medical community.

If the infection is caught early, antibiotics can often successfully treat it and avoid any lasting problems. Sadly, many people don’t even realize they have been bitten by a tick. One study showed that only 17% of those surveyed recalled being bitten. When Lyme disease remains undiagnosed, it allows the infection to fester, wreak havoc on the immune system, cause a host of inflammatory responses, reduce blood flow, and impair healthy brain function.

Lyme disease isn’t the only infection that can interfere with brain function. Bacteria, parasites, viruses and other infectious agents that can cause inflammation and lead to brain disorder include:

  • Streptococcus—strep throat
  • Toxoplasma gondii—a tiny single-celled parasite that is often carried in cats and shed in their feces
  • Fungal infections—commonly an overgrowth of Candida albicans, a yeast found in the mouth, gut, and genitals
  • West Nile virus—a mosquito-borne disease
  • Meningitis—inflammation of the tissues surrounding the brain and spinal cord
  • Epstein-Barr virus—a member of the herpes family
  • Influenza—the common flu bug
  • Herpes viruses—one of the most common human viruses
  • Syphilis
  • Cytomegalovirus
  • Helicobacter pylori
  • Chlamydia pneumoniae

Lyme disease, as well as these other infectious agents, can mimic or cause a multitude of symptoms. Some of these will be explored in greater detail below.


It is well known that Lyme disease and other infections can cause physiological symptoms, including fevers, swollen glands, sore throat, headache, and joint pain or swelling. But many people are unaware that they can also lead to cognitive and neuropsychological issues.

Lyme disease symptoms include:

  • Short attention span
  • Trouble with focus, concentration, and impulse control
  • Poor judgment
  • Memory problems
  • Poor problem-solving and decision-making abilities
  • Slower mental processing speed
  • Impaired speech functions
  • Disorganization
  • Hallucinations
  • Changes in personality
  • Getting lost
  • Eating issues
  • Problems sleeping
  • Decreased libido
  • Addictive behaviors
  • Violence
  • Suicide

70% of those afflicted with Lyme disease report changes in their thinking, such as memory loss and reduced mental sharpness.

Streptococcus symptoms include:

  • Obsessive thoughts
  • Compulsive rituals
  • Overwhelming fears
  • Tics

Toxoplasma gondii symptoms include:

  • Impulsive behavior
  • Dramatic mood swings
  • Hallucinations
  • Memory problems
  • Anxiety
  • Depression
  • Suicidal thoughts


Because untreated Lyme disease and other brain infections can mimic or lead to psychological symptoms and cognitive issues, people with infections are often misdiagnosed with psychiatric illnesses or cognitive dysfunction.

Lyme disease can be misdiagnosed as or lead to:

  • Depression
  • Bipolar disorder
  • Anxiety
  • PTSD
  • Schizophrenia
  • Psychosis
  • Alzheimer’s disease or other dementias
  • Developmental disorders
  • Autism spectrum disorders
  • Eating disorders

Streptococcus can be misdiagnosed as or lead to:

  • Obsessive compulsive disorder
  • Tourette’s syndrome

Toxoplasma gondii can be misdiagnosed as or lead to:

  • Schizophrenia
  • Bipolar disorder
  • Anxiety
  • Depression
  • Alzheimer’s disease
  • Parkinson’s disease

Traditionally, the medical community has dismissed the fact that infections can be associated with these types of symptoms, but that is changing. A 2016 editorial in the Journal of Alzheimer’s Disease written by a worldwide group of 33 scientists suggested the medical community has been neglecting to look at infectious diseases as a root cause of many memory problems, including Alzheimer’s disease and other dementias.


When people with undetected Lyme disease or other infections are misdiagnosed with psychiatric illnesses or cognitive dysfunction, treatments often don’t work. And in some cases, they can make symptoms worse. Without the appropriate treatment, the infection persists, causing further injury to the brain.

This can eventually lead to trouble in all areas of your life, including decreased productivity at work, poor school performance, and problems in relationships. Without the appropriate treatment, Lyme disease or other infections can steal your mind and steal your life.

For people who are not responding to treatment for their symptoms, it is very important to investigate whether an underlying infection may be contributing to the issue.


SPECT is a brain imaging test that measures blood flow and activity in the brain. It shows three things: healthy activity, underactive areas, and overactive areas. On brain scans, infections in the brain can appear as an overall pattern of significantly high or low blood flow and may look similar to a brain affected by toxins.

When these abnormal brain patterns are visible, it indicates a potentially infectious process at work. When we see evidence of infectious disease on SPECT scans, we look for it with additional testing.

With a comprehensive evaluation, you can get an accurate diagnosis and a treatment plan that is targeted to your needs.


At Amen Clinics, we have extensive experience diagnosing and treating Lyme disease and other infections, and particularly the neuropsychiatric symptoms that these infections can cause. Unlike traditional psychiatry, which remains the only medical field that rarely looks at the organ it treats, Amen Clinics use brain SPECT imaging to take the guesswork out of psychiatry. Based on our brain imaging work—over 150,000 functional brain scans and growing—we can identify patterns in the brain that suggest an infection may be the root cause of symptoms.

Our brain SPECT scans can also:

  • Monitor how well treatment is working so adjustments can be made for faster healing
  • Find out if there are other co-occurring conditions or other underlying issues that also need treatment
  • Reducing emotional pain and stigma by demonstrating that symptoms and behaviors are not a personal failure
  • Increasing treatment compliance by showing images of your progress
  • Helping families gain a better understanding of their loved one’s condition

At Amen Clinics, we also assess other factors—biological, psychological, social, and spiritual—that can contribute to symptoms and offer the least toxic, most effective treatments and strategies to optimize these areas of your life.
