I continued to read the article and here is what I have come up with:
Visual halluciations are the most common feature of drug -related pyscosis in PD. The halluciations are typically formed, non threating images of people, animals,and less commonly objects. For many patients, the images are familar, and the peoples seen may even be realitives or friends who are living or dead. Additionally,children, babies, or liliputian figures may be percieved. Threating or frightening halluciations may occur in approximatly 30 per cent of hallucinating PD patients. The majority of patients have insight and reconize the phenomena as halluciations, yet they may still describe them to family members and interact by speaking to them or chasing them. In most instances,at any one time,illusions and halluciations are fleeting and disappear when the patient focus on them or attempts to move closer to them.The occurance of halluciations and illuisions may be associated with the time of day or the lighting. Patients commonly report an increased frequency during the eveining and nighttime hours.Other patients complain of these events immediatly upon awakening and have difficulity distinguishing the illusions/halluciations from dreams. Tactile and auditory halluciations can occur but are less frequent. Often halluciations occur in the context of of sleep disruption and fragmentation, vivid dreams and nightmares with alteration in sleep architecture.
