Performance on the Picture Description Tasks in Patients with Late Dementia of the Alzheimer’s Type

Linguistic problems such as word finding difficulties, writing disorders, problems in phonetic and syntactic use are one of the most important problems seen in individuals with Alzheimer’s Disease (AD). Compared to late onset, early onset dementia patients experience these problems at a faster rate. However; the linguistic abilities of LAD patients are quite similar to the healthy people. In this study, the picture description performance of late onset AD patients and healthy people were compared in terms of affirmative, negative and interrogative sentence structures. According to the results, there is a significant difference within groups. Late onset AD patients produced more declarative and interrogative sentences in picnic picture description test.
