Effecting three of every 100,000 births, Batten Disease affects the body’s ability to discard cellular wastes like lipids and proteins leading to build up in cells. The build up can cause seizures, vision loss as well as cognitive and mobility impairments. Occupational therapist, Virginia B. Goddard, developed the Batten Disease assessment to better encapsulate patients’ functional abilities. The assessment measures patients’ daily activities, functional fine motor skills, visual abilities, stereognosis abilities, sensory responses and behavior. These categories are broken down into smaller activities and each activity is scored on a scale of 0 to 4: 0 marking minimal to no impairment and 4 marking severe or complete impairment. At the end of the assessment, occupational therapists can calculate a final score out of 76 to measure impairment severity.
