  • Zolpidem-induced distortion in Visual Perception
    Annals of Pharmacotherapy, 2003
    Co-Authors: Chiung Lei Huang, Chi-feng Hung, Ching-jui Chang, Hsi Yen Lin
    Abstract:

    OBJECTIVE: To describe a patient who developed Visual Perception distortion after a single dose of zolpidem. CASE SUMMARY: A 50-year-old Asian woman had been prescribed conjugated estrogen 1 tablet daily for hormone replacement therapy and tricalcium phosphate twice daily for osteoporosis. One day, she took zolpidem 10 mg for insomnia as well as acetaminophen 500 mg for headache at bedtime and began to have Visual Perception distortion (e.g., the shapes of objects were twisted, houses were crooked) within 20 minutes, lasting for approximately 30 minutes, and then her vision returned to normal. She only partially recalled the event. She had never taken zolpidem before, and she had not had any such disturbances in the past. DISCUSSION: There have been 21 case reports of zolpidem-related psychotic symptoms in the literature; however, the exact mechanism by which zolpidem may cause Visual Perception changes is undetermined. Many factors have been correlated with zolpidem-induced Visual experiences, such as pharmacokinetic factors, gender, age, and hypoalbuminemia. This patient shared certain similarities such as gender, dosage, and time of onset and duration of adverse reactions. CONCLUSIONS: An objective causality assessment revealed that the zolpidem-induced Visual Perception distortion in this patient was probable. Clinicians should be aware of the potential for Visual Perception distortion, as this is an uncommon adverse effect.

  • Visual memory and Visual Perception recruit common neural substrates.
    Behavioral and Cognitive Neuroscience Reviews, 2004
    Co-Authors: Scott D. Slotnick
    Abstract:

    This human neuroimaging review aims to determine the degree to which Visual memory evokes activity in neural regions that have been associated with Visual Perception. A Visual Perception framework is proposed to identify cortical regions associated with modality-specific processing (i.e., Visual, auditory, motor, or olfactory), Visual domain-specific processing (i.e., “what” versus “where,” or face versus Visual context), and Visual feature-specific processing (i.e., color, motion, or spatial location). Independent assessments of Visual item memory studies and Visual working memory studies revealed activity in the appropriate cortical regions associated with each of the three levels of Visual Perception processing. These results provide compelling evidence that Visual memory and Visual Perception are associated with common neural substrates. Furthermore, as with Visual Perception, they support the view that Visual memory is a constructive process, in which features or components from disparate cortical re...

These results provide compelling evidence that Visual memory and Visual Perception are associated with common neural substrates. Furthermore, as with Visual Perception, they support the view that Visual memory is a constructive process, in which features or components from disparate cortical regions bind together to form a coherent whole.
