Loss of empathy in frontotemporal dementia linked to brain activity changes

Patients with frontotemporal dementia often lack the ability to empathize. A study at Karolinska Institutet has now shown that these patients do not show the same brain activity as healthy individuals when they witness the pain of others, a finding that it is hoped will increase understanding of this specific dementia disease.
