Visual hallucinations (VHs) are common in Parkinson's disease (PD), with prevalence ranging from 27-50% in cross-sectional cohorts of patients with well-established disease. However, minor hallucinations may occur earlier in the disease process than has been previously reported.

Visual hallucinations (VHs) can occur in several clinical conditions, of which the dementias, broadly defined, and Parkinson's disease rank among the most common. There is limited research on the live...
Visual hallucinations (VH) have a significant impact on quality of life for people with Parkinson's disease (PD). A major reason for this is the well-established link with cognitive impairment, but th...
Hallucinations can occur in single or multiple sensory modalities. Historically, greater attention has been paid to single sensory modality experiences with a comparative neglect of hallucinations tha...
Based on a brief overview of the various aspects of schizophrenia reported by numerous studies, here we hypothesize that schizophrenia may originate (and in part be performed) from visual areas. In ot...
Auditory hallucinations are an important symptom for diagnosing dementia with Lewy bodies (DLB), yet they have received less attention than visual hallucinations. We investigated the clinical features...
Parkinson's disease is characterized not only by motor symptoms but also by psycho-behavioral symptoms including Visual Hallucinations (VH) and illusions (I), that are generally associated...
This randomised, double-blind, placebo-controlled trial will evaluate the efficacy of continuous apomorphine infusion compared to placebo in PD patients with visual hallucinations, inadequ...
The study is a pilot study of Cognitive therapy for people with psychosis who have distressing visual hallucinations. The aim is to evaluate whether this is an acceptable, feasible and eff...
Occurrence of visual hallucinations (VHs) in schizophrenia depend in part on disorders in the processing of late visual information (Top-Down). The broader question of how these top-down m...
The primary objective is to demonstrate that the investigational new drug, ACP-103, is well tolerated by, and will not worsen parkinsonism in, patients with Parkinson's disease and psychos...
Repetitive visual hallucinations experienced mostly by elderly with diminished visual acuity or visual field loss, with awareness of the fictional nature of their hallucinations. It is not associated with delusions and other sensory hallucinations.
Parkinsonism following encephalitis, historically seen as a sequella of encephalitis lethargica (Von Economo Encephalitis). The early age of onset, the rapid progression of symptoms followed by stabilization, and the presence of a variety of other neurological disorders (e.g., sociopathic behavior; TICS; MUSCLE SPASMS; oculogyric crises; hyperphagia; and bizarre movements) distinguish this condition from primary PARKINSON DISEASE. Pathologic features include neuronal loss and gliosis concentrated in the MESENCEPHALON; SUBTHALAMUS; and HYPOTHALAMUS. (From Adams et al., Principles of Neurology, 6th ed, p754)
Proteins associated with sporadic or familial cases of PARKINSON DISEASE.
Manganese poisoning is associated with chronic inhalation of manganese particles by individuals who work with manganese ore. Clinical features include CONFUSION; HALLUCINATIONS; and an extrapyramidal syndrome (PARKINSON DISEASE, SECONDARY) that includes rigidity; DYSTONIA; retropulsion; and TREMOR. (Adams, Principles of Neurology, 6th ed, p1213)
A neurodegenerative disease characterized by dementia, mild parkinsonism, and fluctuations in attention and alertness. The neuropsychiatric manifestations tend to precede the onset of bradykinesia, MUSCLE RIGIDITY, and other extrapyramidal signs. DELUSIONS and visual HALLUCINATIONS are relatively frequent in this condition. Histologic examination reveals LEWY BODIES in the CEREBRAL CORTEX and BRAIN STEM. SENILE PLAQUES and other pathologic features characteristic of ALZHEIMER DISEASE may also be present. (From Neurology 1997;48:376-380; Neurology 1996;47:1113-1124)
Parkinson's is a progressive neurological condition, affecting one person in every 500, 95% of which are over 40. It is caused by degeneration of more than 70% of the substantia nigra, which depletes the dopamine (the neurotransmitter involved in pro...
