Paulsen, J. S., & Long, J. D. (2014). “Neuropsychiatric aspects of Huntington’s disease”. Journal of Neurology, Neurosurgery & Psychiatry, 85(2), 139-147.

In FTD, the primary issues are behavioral and language problems, while constructional skills are relatively preserved until later stages of the disease.
