“…26 However, inanimate infestations of the skin have been described in select case reports. [27][28][29][30][31][32] In the past decade, there has been increased interest in patients who report that ''fibers'' are coming out of their skin; the term Morgellons disease has been used colloquially to describe this presentation. Infesting pathogens were sometimes vividly described by our patients, who occasionally attributed biologically impossible characteristics to them.…”

ÖZETParkinson hastalığı ve delüzyonel parazitoz birlikteliği: Bir olgu sunumu Delüzyonel parazitoz kişide, vücudunun parazitler ya da küçük canlılar tarafından sarıldığına dair hatalı ve değiş-tirilemez bir inancın olduğu, az rastlanılan psikiyatrik bir hastalıktır. Her ne kadar her yaşta delüzyonel parazitoz görülebilse de, bazı araştırmalar yaşla birlikte, özellikle kadın cinsiyetinde görülme sıklığının arttığını öne sür-mektedir. Hastalık, genellikle birincil ve ikincil delüzyonel parazitoz olarak sınıflandırılmaktadır. İlki, saptanabilen herhangi bir hastalık sebebi olmayan hastaları kapsarken, ikincil delüzyonel parazitoz grubu genel organik durumla, diğer psikiyatrik hastalıklarla ve bazı maddelerle ilişkilidir. Bu olgu bildiriminde, 15 yıllık Parkinson hastalığı öyküsü bulunan 57 yaşında bir kadın hasta sunulmaktadır. Hastanın, vücudunun parazitler tarafından sarıldı-ğı düşüncesine sahip olduğu, psikiyatrik görüşme sırasında fark edilmiştir. Bu yazıda, Parkinson hastalığı ve delüzyonel parazitoz birlikteliği tartışılmaktadır. Anahtar kelimeler: Delüzyonel parazitoz, Parkinson hastalığı, dopamin ABSTRACT Comorbidity of Parkinson's disease and delusional parasitosis: a case reportDelusional parasitosis is a rare psychiatric disorder in which a person has the false and persistent belief of being infested with parasites or small living creatures. Although delusional parasitosis may occur at any age, some researchers suggest an increase in frequency in the elderly, especially in women gender. The disorder usually classified as primary and secondary delusional parasitosis. The first one contains patients without a detectable cause while the secondary delusional parasitosis group is associated with general organic conditions, other psychiatric illnesses and some drugs. In this case report, we present a 57 years-old woman who has Parkinson's disease for 15 years. Her psychiatric interview revealed her persistent thoughts about being infested by parasites. In this paper, we discussed delusional parasitosis comorbidity in Parkinson's disease.

Parkinson's disease (PD) psychosis is a common phenomenon that affects quality of life, caregiver burden, and disability in patients with PD. Although there may be an increased risk of psychosis inherent to the disease itself, current research suggests that dementia, advancing age, and concomitant medication use increase the risk of psychosis in PD. Symptoms of psychosis in this population may include hallucinations, delusions, paranoia, false sense of presence, and illusions. Early intervention may be important for delaying progression of psychotic symptoms. Treatment options for PDrelated psychosis include reduction of dopaminergic therapy, switch to levodopa, simplification of polypharmacy and addition of an atypical antipsychotic, such as quetiapine and clozapine.Parkinson's disease (PD) is a chronic, progressive neurodegenerative disorder characterized by tremor, bradykinesia, rigidity, and postural instability. The presence of psychotic symptoms, or PD psychosis (PDP), is a recognized symptom cluster, and has serious consequences for patients. Psychotic symptoms experienced by PD patients may include hallucinations (primarily visual, but also auditory), illusions, paranoia, delusions, and a milder 'false sense of presence' . Psychotic symptoms are associated with poorer quality of life, disability, caregiver distress and worse outcomes including mortality and nursing home placement [1,2]. Given the impact of psychosis on this chronic, progressive neurodegenerative disease, current research aims to further understand the epidemiology of psychotic symptoms, the risk factors for psychosis, and most appropriate treatments.The prevalence of psychotic symptoms varies widely in the literature and may be as high as 60% in the PD population [3][4][5][6]. A recent population-based study of PDP revealed an incidence of 797 per 1,000 person-years. At the end of the 12-year study period, 60% of patients had developed psychotic symptoms [7]. The difficulty in assessing the frequency of this condition may be related to a lack of consensus on methods to define what constitutes PDP, subsequent use of multiple rating scales in the literature, and differences in study design and patient population.

Three cases of delusional parasitosis caused by dopamine agonists

Abstract: We report three cases of delusional parasitosis (DP) in patients with well-established Parkinson's disease, all of whom were taking dopamine agonists. In all three cases, the DP resolved rapidly when the drug was withdrawn.
