Understanding Rapidly Progressive Dementia

This chapter explores the varied etiologies of rapidly progressive dementia, categorizing symptoms, differential diagnoses, and specific disease considerations according to different pathological categories. It emphasizes the need for recognizing a range of potential causes including vascular, infectious, toxic metabolic, autoimmune, mitochondrial, and malignant origins. The discussion underscores the challenges in diagnosis, the importance of thorough evaluation, and the collaboration between neurologists and psychiatrists, paving the way for understanding neurodegenerative processes such as critical basal degeneration.
