Occupational therapy for a patient with Parkinson's disease who complained of difficulty reading

Abstract

We experienced a case with Parkinson's disease who complained of difficulty reading letters. The cause of the reading difficulty was considered to be a reduction in contrast sensitivity. By changing the color tone, width, and size of the letters, the readability of the cases was improved. We considered that the contrast-enhancing operation, i.e., facilitating the detection of the boundary between the background and the visual object, was effective in solving the problem. The case was able to acquire a solution to the reading difficulty. It is important to understand the pathophysiology characteristic of the disease. In addition, understanding and verifying the life situation in which the problem occurs helps determine the cause and respond to it.
