Difficulty to interpret visual stimuli
As the disease progresses, and depending on the type of dementia, patients may have difficulty to interpret visual stimuli. When a task requires visual coordination, they fail to complete it and lose interest. Even patients who were experts in sewing or knitting may start losing their skills and feeling upset about it.
Driving is another important skill that becomes compromised as dementia progresses, and it is not a good idea to have a patient with dementia driving, even when he seems to be in an early phase. Other visual skills that become compromised are reading and organizing, which contributes to the dependence of the patient and his difficulty to learning new things.
