Parasitosis delusions patients frequently seek treatment from a doctor or dermatologist (skin doctor), claiming to have a parasitic illness within their body or on their skin.

A crawling sensation on the skin is another typical symptom reported by patients with delusional parasitosis. Formication is the medical name for this condition.

Delusional parasitosis causes

It’s unclear why some people suffer from parasitosis delusions. Women in their forties and fifties are more likely to suffer from this mental illness. However, it is available to men and women of all ages.

Delusional parasitosis can occur as a result of a chemical imbalance in the brain caused by various medical conditions. It’s also possible that it’s connected to drug usage or addiction, such as cocaine addiction.

The exact location of this disease in the brain is unknown. According to some experts, psychosis (seeing, believing or hearing something that’s not there) is thought to be caused by the brain neurotransmitter dopamine. Too much dopamine in the brain can be caused by severe stress or other illnesses.


If you suspect you have this disease, your doctor will do a thorough physical examination. They may also perform blood tests to rule out other possible reasons for skin itching, numbness, crawling and other symptoms that are comparable to delusional parasitosis.

These are some of the other possibilities:

  • Anemia
  • Thyroid disease
  • Kidney disease
  • Lymphoma
  • Scabies infection
  • Louse infection
  • HIV infection
  • Dermatitis herpetiformis
  • Nerve disorders
  • Parkinson’s disease
  • Fibromyalgia
  • Medications (amphetamines, methylphenidate)
  • Morgellons disease
  • Alcohol misuse
  • Substance abuse

Delusional parasitosis treatment

Any underlying problems must be treated as part of the treatment for delusional parasitosis. If a triggering disease exists, treating it might help to alleviate or end the parasitosis delusions.

Antipsychotic medicines may be prescribed by a doctor or psychiatrist. Delusional parasitosis patients may refuse to take these drugs because they feel they are suffering from a parasitic infection rather than a mental illness.

Therapy and consultations with a trustworthy doctor or psychiatrist may be beneficial. Because many family physicians and dermatologists are unfamiliar with medicines and therapies for this condition, it’s important to consult a psychiatrist.

For parasitosis delusions, a psychiatrist may prescribe antipsychotic medications such as:

  • Pimozide (Orap)
  • Aripiprazole (Abilify)
  • Risperidone (Risperdal)\solanzapine (Zyprexa)

It’s not always possible to talk someone out of parasitosis delusions. A doctor can recommend you to a psychiatrist in these situations.
