"Eye Changes as Early Indicator of Alzheimer's and Dementia, Scientists Find"

A study led by UCSF has linked posterior cortical atrophy (PCA) to Alzheimer’s disease, highlighting the unique challenges faced by PCA patients and stressing the importance of early detection and potential treatment options. The research, involving over 1,000 patients globally, underscores the need for increased awareness and diagnostic precision to improve patient care and advance Alzheimer’s research. The study found that 94% of PCA patients had Alzheimer’s pathology, emphasizing the need for better tools and training to identify these patients early on and get them treatment. Early identification of PCA may have important implications for Alzheimer’s treatment, as patients with PCA may be candidates for anti-amyloid and anti-tau therapies.
