Disclaimer:

This list of dementia types and subtypes was manually compiled based on available online resources. While every effort has been made to ensure the accuracy of the information, it is important to note that I cannot guarantee the completeness or absolute accuracy of the content. The list was created through 8 hours of online research and reflects the information available at that time. No single comprehensive source was found to cover all types and subtypes of dementia. For the most up-to-date and reliable information, I encourage further personal research.
