Researchers at the University of Queensland in Australia have announced the development of two new visual tests aimed at helping to distinguish between dementia associated with Lewy bodies and Alzheimer's disease, by assessing the brain's ability to recognize objects and process visual information, thereby contributing to improved patient evaluation.
The science website Tech Explorist reported on Thursday that the two tests rely on measuring how the brain processes images. The first asks participants to identify images that start blurry and gradually become clearer, while the second focuses on detecting hidden numbers within blurred images.
Study results showed that patients with dementia associated with Lewy bodies faced greater difficulties in processing visual information compared to those with Alzheimer's disease. These difficulties were also linked to visual hallucinations, which involve seeing things or people that are not actually present.
Researchers noted that the two tests could help assess visual perception disorders and monitor their progression, but they do not replace necessary medical examinations and evaluations. Further studies are still needed to verify their accuracy and potential utility in diagnosis.
Dementia associated with Lewy bodies is one type of dementia caused by abnormal accumulations of protein within brain cells. It can affect thinking, attention, movement, and visual perception. Some of its symptoms overlap with those of Alzheimer's disease and Parkinson's disease, making it important to distinguish between these conditions to determine appropriate care.
