Willis-Ekbom disease, also known as delusional parasitosis, is a rare and intriguing psychiatric disorder characterized by a persistent delusion that one is infested with parasites, such as insects, worms, or other small organisms. This condition is named after the two doctors who first described it: Drs. George F. Willis and Karl Ekbom. Despite its rarity, Willis-Ekbom disease can have a significant impact on a person's quality of life, causing considerable distress and impairment in daily functioning.
The exact prevalence of Willis-Ekbom disease is not well-established, but it is considered a rare condition. According to various studies, the estimated incidence rate ranges from 1 to 4 cases per 100,000 people per year. Women are more frequently affected than men, and the condition typically manifests in middle-aged or older adults. While the causes of Willis-Ekbom disease are not fully understood, research suggests that it may be related to a combination of genetic, environmental, and psychological factors.
Causes and Risk Factors of Willis-Ekbom Disease
While the exact causes of Willis-Ekbom disease are still not fully understood, research has identified several potential risk factors and contributing factors. These include:
- Genetic predisposition: Family history of psychiatric disorders, such as schizophrenia or mood disorders, may play a role in the development of Willis-Ekbom disease.
- Psychological factors: Stress, anxiety, and depression can contribute to the onset of delusional parasitosis.
- Substance abuse: The use of certain substances, such as cocaine or amphetamines, may trigger or exacerbate symptoms of Willis-Ekbom disease.
- Medical conditions: Certain medical conditions, such as dermatitis or infestations, can increase the risk of developing delusional parasitosis.
Symptoms of Willis-Ekbom Disease
The primary symptom of Willis-Ekbom disease is a persistent and fixed delusion that one is infested with parasites. This delusion can manifest in various ways, including:
Physical sensations: Patients may report feeling sensations of crawling, biting, or stinging on their skin.
Visual hallucinations: Some individuals may see parasites on their skin or in their surroundings.
Delusional thinking: Patients may believe that they are infested with specific types of parasites and may attempt to extract them using various methods.
In addition to these primary symptoms, individuals with Willis-Ekbom disease may also experience:
- Anxiety and depression
- Social isolation and withdrawal
- Sleep disturbances
- Impaired daily functioning
Treatment Options for Willis-Ekbom Disease
Treatment for Willis-Ekbom disease typically involves a combination of psychotherapy, medication, and supportive care. The primary goals of treatment are to alleviate symptoms, improve daily functioning, and enhance quality of life.
Psychotherapy
Cognitive-behavioral therapy (CBT) and other forms of psychotherapy can help individuals with Willis-Ekbom disease to:
- Identify and challenge delusional thinking patterns
- Develop coping strategies and problem-solving skills

Antipsychotic medications, such as risperidone or olanzapine, may be used to treat symptoms of Willis-Ekbom disease, including delusions and hallucinations. Selective serotonin reuptake inhibitors (SSRIs) may also be prescribed to manage anxiety and depression.
Supportive Care
Supportive care, including education and counseling, can help individuals with Willis-Ekbom disease and their families to:
- Understand the condition and its treatment
- Develop strategies for managing symptoms
- Improve communication and relationships
