The clinical diagnosis of posterior cortical atrophy (PCA) has been established for more than 3 decades. Yet, this diagnostic entity only has obtained valuable academic attention in recent years. The cognitive profile of PCA is well documented and underlying pathology is extensively investigated. By contrast, the neuropsychiatric manifestation of PCA is rarely discussed in the medical literature. Based on the longitudinal observational study, this author has noted 3 stages or aspects of neuropsychiatric presentation of PCA through the disease course. More importantly, without effective treatment, neuropsychiatric symptoms play a major role in causing caregiver burden.
