Common Visual Spatial Changes in Alzheimer’s Disease

Our clients with dementia may experience changes in how they perceive the world around them. Perception frequently changes with the progression of their dementia. Dementia damages the brain, if this damage is in areas that help process images the individual will see things differently and have problems with vision and spatial awareness. Deficits in visual spatial skills can increase risks of falls, contribute to unawareness of their relationship to the environment, and increase their propensity to get lost or find their way. This webinar will introduce the common causes of visual issues in the elderly and clients with dementia, and review strategies to assist the dementia client with their visual problems.

Objectives

1. Recognize the prevalence and frequency of visual issues in the Dementia/ Alzheimer’s population.
2. Identify causes and understand the importance of addressing visual issues in the Dementia /Alzheimer’s client.
3. Employ treatment ideas to address visual problems associated with dementia.

Outline

1. Review the prevalence and the common visual changes that occur with Normal Aging and Dementia
2. Identify some of the common causes of visual issues in the elderly.
3. Discuss problems clients with Dementia may deal with on a daily basis due to visual issues.
4. Review strategies to maximize success with the visually impaired dementia client.
