Semantic Memory Impairment

Semantic Memory Impairment is a cognitive deficit characterized by the progressive deterioration of semantic memory—the ability to acquire, store, and retrieve general world knowledge and conceptual information—distinguishing it from impairments in episodic or procedural memory, and commonly observed in neurodegenerative conditions such as Primary Progressive Aphasia and stroke-induced Receptive Aphasia.
