Lyme Disease Mental Symptoms: Causes, Diagnosis, and Treatment Options

Lyme disease is a bacterial infection caused by the bite of an infected tick. It is most commonly associated with physical symptoms, but it can also have mental health effects. In this article, we will explore the mental symptoms associated with Lyme disease.

What are Lyme Disease Mental Symptoms?

Lyme disease can affect the central nervous system and cause a range of mental health symptoms. Here are some of the most common ones:

  1. Cognitive impairment

Lyme disease can cause cognitive impairment or “brain fog.” This can make it difficult to concentrate, remember things, and process information. Some people with Lyme disease describe feeling like their brain is in a fog or like they are moving in slow motion.

  1. Mood disorders

Lyme disease can cause mood disorders such as depression and anxiety. People with Lyme disease may feel sad, hopeless, or irritable. They may also experience anxiety, panic attacks, and feelings of fear or dread.

  1. Sleep disorders

Lyme disease can disrupt sleep and cause sleep disorders such as insomnia or hypersomnia (excessive sleepiness). People with Lyme disease may have trouble falling asleep, staying asleep, or getting restful sleep. They may also feel excessively sleepy during the day.

  1. Psychosis

In rare cases, Lyme disease can cause psychosis, which is a severe mental disorder characterized by a loss of touch with reality. Symptoms of psychosis may include delusions, hallucinations, and disorganized thinking and speech.

How to Relieve Lyme Disease Mental Symptoms?

If you are experiencing mental symptoms of Lyme disease, it is important to seek medical attention. Here are some ways to relieve mental symptoms:

  1. Antibiotics

Antibiotics are the primary treatment for Lyme disease. If the infection is caught early enough, a course of antibiotics may help alleviate mental symptoms.

  1. Psychotherapy

Psychotherapy can be helpful for people with Lyme disease who are experiencing mental health symptoms. A therapist can help you work through feelings of depression, anxiety, and other emotions related to Lyme disease.

  1. Support groups

Support groups can provide a safe space to share your experiences with others who are also struggling with Lyme disease. They can be a source of emotional support and practical advice.

  1. Lifestyle changes

Making certain lifestyle changes can also help relieve mental symptoms of Lyme disease. For example, getting regular exercise, eating a healthy diet, and getting enough restful sleep can all help improve mental health.

How long do Lyme Disease Mental Symptoms last?

The duration of mental symptoms associated with Lyme disease can vary depending on the individual and the severity of the infection. Some people may experience only mild symptoms that resolve quickly with treatment, while others may experience more severe and long-lasting symptoms.

In some cases, mental symptoms of Lyme disease can persist even after the infection is treated. This is known as post-treatment Lyme disease syndrome (PTLDS). PTLDS can cause ongoing cognitive impairment, fatigue, and pain. It is important to seek medical attention if you are experiencing symptoms of PTLDS.


Lyme disease can have a range of mental health effects, including cognitive impairment, mood disorders, sleep disorders, and in rare cases, psychosis. If you are experiencing mental symptoms of Lyme disease, it is important to seek medical attention. Treatment with antibiotics, psychotherapy, support groups, and lifestyle changes can all help relieve mental symptoms. The duration of mental symptoms can vary, and in some cases, they may persist even after treatment is completed.
