Primary progressive aphasia (PPA) is a neurological syndrome that affects a person's ability to communicate. It is characterized by a gradual decline in language skills, impacting speaking, understanding, reading, and writing. PPA is often caused by neurodegenerative diseases, such as frontotemporal dementia. There are three main variants of PPA: nonfluent/agrammatic variant, semantic variant, and logopenic variant. Each variant presents different language difficulties. For example, the nonfluent variant involves struggles with speech production, while the semantic variant affects comprehension and word meaning. Early diagnosis and intervention can help manage symptoms and improve quality of life.
