Summary: Frontotemporal dementia, affecting about 3% of dementia sufferers in Sweden, is characterised by a lack of empathy that challenges sufferers and their households.
Using purposeful MRI, researchers discovered that sufferers confirmed no activation in mind networks related to empathy when viewing distressing photographs, not like wholesome people. This lack of mind exercise strongly correlated with caregivers’ assessments of diminished empathy, confirming a hyperlink between mind perform and habits.
The findings might enhance understanding of this situation and assist distinguish it from different psychiatric issues with comparable signs, like psychopathy.
Key Facts:
- Frontotemporal dementia sufferers present no mind activation in empathy networks.
- Brain exercise correlates strongly with caregivers’ studies of empathy loss.
- Empathy deficits complicate social interactions and care selections.

Around 25,000 Swedes are affected by dementia yearly. Of these, about three % are identified with frontotemporal dementia. The illness is tough to diagnose, however one in all its traits is that victims lose the power to empathize, which may result in issues for them, and never least for his or her kin.
In the present research, led by researchers Olof Lindberg at Karolinska Institutet and Alexander Santillo at Lund University, 28 sufferers identified with frontal lobe dementia had been analyzed utilizing purposeful magnetic resonance imaging (fMRI).
The researchers had been capable of see how the themes’ mind exercise was affected once they had been proven photographs of palms being penetrated by needles, which usually prompts the elements of the mind that are inclined to react to the expertise of struggling or ache in others.
The research exhibits that folks with frontotemporal dementia don’t show any activation of the frontal mind networks which can be activated within the management group of age-matched wholesome people.
“What is especially fascinating is that we now have been capable of relate this measure of mind exercise in sufferers to how carers fee their lack of empathy. There turned out to be a robust correlation, and that’s essential. It exhibits that what occurs within the mind is related to the individuals’s habits,” says Olof Lindberg.
Dementia normally means reminiscence issues, however frontotemporal dementia with a lack of capability to empathize with different individuals can resemble different situations with empathy issues in psychiatry, corresponding to psychopathy. Olof Lindberg believes that the brand new findings on how mind exercise is affected will improve understanding of the illness.
“This captures a key symptom in sufferers, and with an absence of empathy, it naturally turns into harder to behave socially. So, it could actually have an effect on the judgement of whether or not to be cared for at house, for instance.”
The research was carried out in collaboration between Skåne University Hospital, Norrland University Hospital and Karolinska University Hospital Huddinge.

Abstract
Altered empathy processing in frontotemporal dementia
Loss of empathy is a core symptom of behavioral variant frontotemporal dementia (bvFTD). In explicit, the affective facet of empathy seems to be impartial of lower within the different socioemotional talents and common cognition in bvFTD.
We used a longtime purposeful magnetic resonance imaging (MRI) paradigm to evaluate bvFTD-related alterations in mind responses throughout empathy for ache (EFP) in a case-control research.
