Abstract. Hallucinations occur in up to 40 % of patients with Parkinson's disease (PD) and are mainly of a visual nature. We prospectively studied 8 patients with PD and tactile hallucinations (TH). TH occurred with a clear sensorium, and were long-lasting. In most cases they involved animals, were combined with other types of hallucinations occurring simultaneously (mainly formed visual hallucinations), and predominated in the evening and/or at night. Pharmacological and disease-related… 

A review of tactile hallucinations in Parkinsons disease

Auditory and other types of hallucinations are generally accompanied by visual hallucinations, and Tactile hallucinations (THs) rarely occur in patients with PD.

Olfactory and visual hallucinations in Parkinson's disease.

Hallucinations in Parkinson disease

E epidemiological, phenomenological, pathophysiological and therapeutic aspects of hallucinations in PD are presented and better phenomenological discrimination, combined with neuroimaging tools, should refine therapeutic options and improve prognosis.

Psychosis in Parkinson's Disease: Phenomenology, Frequency, Risk Factors, and Current Understanding of Pathophysiologic Mechanisms

Hallucinations may involve several sensory modalities and include visual illusions, passage hallucinations, and sense of presence in Parkinson's disease patients with cognitive impairment.

This is the first report to comprehensively describe the tactile hallucinations experienced by DLB patients, and it is hoped that this report will help inspire new treatments for dementia with Lewy bodies.

Delusion and Hallucination in Parkinson's Disease: A Pilot Study of Clinical Features and Pathogenesis

Those with delusions were associated with longer disease durations, higher levodopa-equivalent daily doses, and use of dopamine agonists, compared with PD patients with hallucinations.

Hallucinations and the spectrum of psychosis in Parkinson's disease

Can dopamine agonists trigger tactile hallucinations in patients with Parkinson's disease?

Risk factors for visual hallucinations in patients with Parkinson’s disease

The data show that the presence of vivid dreams is associated with VHs in PD and reaffirm thatVHs are linked to cognitive impairment, and Investigating vivid dreams may help the identification of VHS in PD.

Psychosis in Parkinson’s disease

Management of psychosis in PD requires a multidisciplinary approach and some of the newer atypical antipsychotics are effective against psychosis with no significant worsening of PD.



Cenesthetic hallucinations in a patient with Parkinson’s disease

A 66 year old woman with Parkinson’s disease, predominantly rigid akinetic, had been treated with carbidopa-levodopa since the age of 55 in 1984 and developed cenesthetic hallucinations during pergolide and levodopa treatment.

Hallucinations in Parkinson's disease: prevalence, phenomenology and risk factors.

Findings indicate that, when minor hallucinations are included, the total prevalence of hallucinations in Parkinson's disease is much higher than previously reported, and a simple side-effect of dopaminergic treatment is not sufficient to explain the occurrence of all visual hallucinations.

Prospective study of hallucinations and delusions in Parkinson's disease

The results suggest that several underlying characteristics of patients with Parkinson's disease (disease severity, dementia, depression, worse visual acuity) may be more important determinants of which patients experience hallucinations.

Complex visual hallucinations. Clinical and neurobiological insights.

It is suggested that perturbation of a distributed matrix may explain the production of similar, complex mental phenomena by relatively blunt insults at disparate sites.

Early dopaminergic drug-induced hallucinations in parkinsonian patients

Early onset drug-related hallucinations are not typical of Parkinson's disease and should signal an investigation of two alternative diagnoses, either a comorbid psychotic illness (often unrevealed by the patient initially) or an evolving parkinsonism-plus syndrome.

Hallucinations, REM sleep, and Parkinson’s disease

The visual hallucinations that coincide with daytime episodes of REM sleep in patients who also experience post-REM delusions at night may be dream imagery and Psychosis in patients with PD may reflect a narcolepsy-like REM sleep disorder.

Intellectual Impairment: Mild but definite impairment of function at home with need of occasional prompting, unable to make judgements or solve problems.

Peduncular hallucinosis associated with isolated infarction of the substantia nigra pars reticulata

The findings suggest that destruction of the pars reticulata may be the essential feature to the development of peduncular hallucinosis.

Accuracy of clinical diagnosis of idiopathic Parkinson's disease: a clinico-pathological study of 100 cases.

The pathological findings in 100 patients diagnosed prospectively by a group of consultant neurologists as having idiopathic Parkinson's disease are reported, and these observations call into question current concepts of Parkinson's Disease as a single distinct morbid entity.

Mini-Mental Parkinson: first validation study of a new bedside test constructed for Parkinson's disease.

This brief test is suitable for assessment of parkinsonian patients and has significant difference in the mean scores in cases with confusional event compared with patients with no such history.
