FTD Disorders

Frontotemporal degeneration is the umbrella term for a range of disorders that impact the frontal and temporal lobes of the brain.

Each disorder can be identified according to the symptoms that appear first and most prominently, whether in behavior (behavioral variant FTD), changes in the ability to speak and understand language (primary progressive aphasia) or in movement (corticobasal syndrome, progressive supranuclear palsy). The clinical syndrome where FTD and ALS occur in the same person is referred to as ALS-Frontotemporal Spectrum Disorder (ALS-FTSD).

FTD Genetics

In some cases, the changes that lead to FTD are caused by variants in a person’s genes. Visit the FTD Genetics section of our website to find out more about the causes of FTD, genetic counseling, and genetic testing options.
