The Unified Parkinson’s disease rating scale (UPDRS 16) motor subscale rates the severity of motor symptoms in idiopathic Parkinson’s disease overall and for each side of the body separately, including measures of tremor, rigidity, and bradykinesia. Included were measures of movement, cognition, and affect including some subtests from the Cambridge neuropsychological test automated battery (CANTAB). All patients fulfilled the Parkinson’s Disease Society brain bank clinical diagnostic criteria for idiopathic Parkinson’s disease. Outpatients with idiopathic Parkinson’s disease who attended the Royal Hallamshire Hospital’s movement disorders clinic between 19 were contacted. We have therefore analysed the nature of hallucinosis typically found in idiopathic Parkinson’s disease to identify demographic features, clinical features, and aspects of cognitive function which distinguish patients with and without hallucinosis. 3 13 14 This study was initiated as a result of our finding of patients with idiopathic Parkinson’s disease of short duration experiencing hallucinosis on relatively low dosages of dopaminergic medication. Hallucinosis is commonly assumed to complicate the later stages of idiopathic Parkinson’s disease when dopaminergic drug treatment has been given for an extended period and high dosage is required to control motor symptoms. 1 An association between cognitive impairment and hallucinosis has been found in some studies, 8 9 but not others. 4 7Īll dopaminergic medications may evoke hallucinosis but there is dispute over which class of medication is the most likely to do so.

6 Vivid dreaming often precedes or coexists with hallucinosis, illusions, and delusions. 4 Delusions occur in about 3%, are usually paranoid, occur on a background of a clear sensorium, 5 and commonly have themes of spouse infidelity or family and physician conspiracy.

1 3-4 Illusions seem to occur less often, in about 6% of treated patients. 2 Often reported are fully formed non-threatening images of people and animals, often at night, on a background of a clear sensorium and stereotyped for the patient. 1The hallucinations are predominantly visual although an auditory component is not uncommon. Patients may have to accept a reduction in dopaminergic medication to relieve psychosis at the expense of mobility.Ībout 30% of patients with idiopathic Parkinson’s disease will experience hallucinosis during dopaminergic treatment. The clinical management of these phenomena is complicated by the adverse motor effects of neuroleptic medication. Neuropsychiatric complications which occur during the treatment of idiopathic Parkinson’s disease include vivid dreaming, illusions, hallucinosis, delusional syndromes, and non-confusional and confusional psychoses. The difference in the pathophysiological basis of hallucinosis in these two groups of patients is discussed. Hallucinosis was not associated with age at onset of idiopathic Parkinson’s disease or dosage of dopaminergic medication.ĬONCLUSION Hallucinosis in idiopathic Parkinson’s disease is heterogeneous, falling into two groups. In all patients with idiopathic Parkinson’s disease, hallucinosis was more prevalent when they were treated with a direct acting dopamine receptor agonist. In patients with idiopathic Parkinson’s disease of longer than five years duration, hallucinosis was associated with postural instability, global cognitive impairment, and lack of depressive affect. In patients with a disease duration of five years or less, hallucinosis was associated with rapid progression of the motor component of the disease but not cognitive impairment. RESULTS There were two subgroups of patients with idiopathic Parkinson’s disease experiencing hallucinosis. METHODS The clinical, demographic, and cognitive correlates of hallucinosis were investigated in a sample of 129 patients with idiopathic Parkinson’s disease.

The aim, therefore, was to investigate the homogeneity of a population of patients with idiopathic Parkinson’s disease and hallucinosis. However, patients with idiopathic Parkinson’s disease of short duration experiencing hallucinosis on relatively low doses of dopaminergic medication have been found. BACKGROUND Hallucinosis is a complication of the treatment of idiopathic Parkinson’s disease commonly thought to afflict older, chronically medicated, cognitively impaired patients.
