Parkinson's disease (PD) is a progressive neurodegenerative disorder clinically diagnosed by the presence of characteristic motor symptoms such as resting tremor, bradykinesia, and rigidity (Leite Silva et al., 2023). However, increasing evidence highlights that PD is also associated with significant non-motor symptoms, including impairments in social cognition (SC), which affect ~20% of patients (Christidi et al., 2018; Dodich et al., 2021; Romosan et al., 2019). SC is a complex cognitive domain that encompasses a range of psychological processes crucial for human interaction, such as recognizing social and emotional cues, processing others' beliefs and intentions, maintaining social knowledge, and generating appropriate behavioral responses (Multani et al., 2019). Despite its relevance, SC has received relatively limited attention in PD research (Chen et al., 2022). This is particularly concerning, as social dysfunction can precede the full clinical onset of PD by several years, emerging before the appearance of overt motor symptoms (Chen et al., 2022; Yu and Wu, 2013). Furthermore, SC plays a fundamental role in navigating social environments and maintaining interpersonal relationships, with deficits in this domain significantly impacting mental health, wellbeing, and overall quality of life (Christidi et al., 2018; Trompeta et al., 2021).

A key component of SC is empathy, which refers to the ability to understand and share the thoughts and emotions of others while also engaging emotionally and caring about their wellbeing (Han et al., 2025). Previous research suggests that patients with PD may exhibit reduced empathic responses, potentially due to neural damage associated with the disease (Coundouris et al., 2020). Empathy relies on the participation of integration of multiple structures including the prefrontal cortex, the anterior cingulate cortex (ACC), the amygdala, the insula, and the basal ganglia—all of which are affected in PD (Rankin et al., 2006).

Most existing research relies on self-report measures, such as the Interpersonal Reactivity Index (IRI; Davis, 1983) or the Empathy Quotient (EQ; Baron-Cohen and Wheelwright, 2004), in which patients are interrogated using empathy-inducing hypothetical situations (de Lima and Osório, 2021). These self-reported measures provide information on dispositional empathy, which refers to a person's stable character trait that exists outside of particular situations (Aparicio-Flores et al., 2020; Cuff et al., 2014). It represents an individual's response tendency to adopt others' perspectives across various contexts, and is considered relatively consistent over time. Dispositional empathy is defined as the automatic generation of empathetic reactions, and is regarded as an innate character trait that cannot be taught (Rameson et al., 2012). Some authors distinguish two components within dispositional empathy, one affective and one cognitive (Davis, 1983). Affective empathy includes emotions directed toward others and cognitive empathy involves the ability to take the perspective of another person's mental state (Mattan et al., 2016). The results obtained in PD patients using these dispositional empathy measures have been very diverse. While some studies report no empathy deficits in PD (Alonso-Recio et al., 2021; Schwartz and Pell, 2017), others find generalized impairments—especially in advanced disease stages (Dodich et al., 2021; Narme et al., 2013; Pomponi et al., 2016)—or specific deficits in cognitive empathy while affective empathy remains intact (Coundouris et al., 2020; Multani et al., 2019; Schmidt et al., 2017).

Nevertheless, empathy can also be measured through situational tasks that assess empathic reactions in specific or immediate contexts (Auné et al., 2015; Cuff et al., 2014; Fernández-Pinto et al., 2008). Particularly, it can be evaluated in stimulated experimental settings by asking subjects to report their feelings immediately after exposure to a situation designed to elicit empathic responses. Therefore, in contrast to dispositional empathy, situational empathy is influenced by an individual's social ability in a particular context, and it manifests in a manner that is more contingent on the circumstances (Aparicio-Flores et al., 2020). In PD, we identified only one study that specifically focuses on situational empathy. In particular, we have identified a study focusing on the concept of pain empathy, in which patients had a decreased empathic response to situations involving the pain of others (Hu et al., 2021). No studies were found that analyzed the capacity of PD patients to respond empathetically to scenarios eliciting basic emotions such as happiness, sadness, anger or fear.

While the distinction between dispositional and situational empathy is less frequently emphasized in clinical literature compared to the more widely recognized dimensions of affective and cognitive empathy, it does not conflict with them. Rather, dispositional and situational empathy refer to the temporal and contextual framing of empathic responses, and both may encompass cognitive and affective components. Therefore, the two frameworks can be viewed as complementary. Focusing on the distinction between dispositional and situational empathy, it is important to examine how these two forms differ. Understanding this distinction is crucial, as the specific empathic emotion experienced in a given context is not necessarily aligned with an individual's general tendency to empathize (Batson et al., 1987; Fabi et al., 2019). Along these lines, neuroimaging studies suggest that brain activity related to empathy correlates more strongly with situational rather than dispositional empathy scores (Bufalari and Ionta, 2013; Lamm et al., 2011; Saarela et al., 2007; Singer et al., 2004). Research examining the relationship between dispositional and situational empathy in healthy individuals has found only modest correlations (Fabi et al., 2019). A meta-analysis reported a mean effect size of r = 0.35 for the association between dispositional empathic concern and situation-specific empathic responses (Zickfeld et al., 2017). These moderate correlations suggest that while related, dispositional and situational empathy represent distinct aspects of empathic functioning. Some researchers argue that empathy is generally more situational than dispositional, noting that self-report measures of dispositional empathy may be susceptible to social desirability bias, self-awareness and verbal expression difficulties (Jauniaux et al., 2020; Zhou et al., 2003). Consequently, combining measures of both situational and dispositional empathy may provide a more comprehensive understanding of empathic capacity. In PD, there is a lack of research exploring the relationship between dispositional and situational empathy in PD, leaving a critical gap in our understanding of how these two dimensions interact in the context of PD.

Another important debate about empathy abilities in PD refers to the dependence on, or independence from cognition, both general and specific processes. Regarding the relationship between empathy and other cognitive domains, the most studied is with executive functions. They have been related to SC abilities in PD (Narme et al., 2013; Yu and Wu, 2013). In fact, lower scores in different SC tasks, such as social perception or theory of mind, have been related to attention, working memory, and other executive function impairments (Assogna et al., 2010; Narme et al., 2011). Nevertheless, other studies have failed to find this link (Alonso-Recio et al., 2014; Bodden et al., 2010; Herrera et al., 2011; Pietschnig et al., 2016; Roca et al., 2010). Moreover, to date, only one study has examined specifically the relationship between empathy and cognition in PD, observing sporadic and non-significant correlations between empathy scores and several cognitive functions (Schmidt et al., 2017). The authors of the study posit that the majority of patients showed only slight cognitive impairments, and that the absence of significant results may be attributable to a ceiling effect in cognitive measures. For their part, Alonso-Recio et al. (2021) studied the relationship between empathy and general cognitive status (measured by the MoCA) of two groups of PD patients (with and without cognitive impairment) and a group of healthy individuals, finding no differences between them. However, changes in empathic ability have been found in people with PD and dementia, with similar patterns to those observed in other neurodegenerative conditions such as Alzheimer's disease (Martinez et al., 2018).

In summary, despite the relevance of empathy in PD, it remains unclear how dispositional and, particularly, situational empathy abilities are affected in this population. Moreover, the relationship between these two types of empathy has not yet been assessed in PD patients. Accordingly, this study aimed to examine both dispositional and situational empathy in individuals with PD. Moreover, given the potential influence of other cognitive functions on these abilities, this research also examined the relationships between both types of empathy measures and various cognitive processes, including processing speed, visuospatial abilities, memory, language, and executive functions. To this end, the present study compared a group of PD patients with cognitive impairment, a group of cognitively-preserved PD patients and an equivalent HC group.

The present study aims to explore the empathic ability of patients diagnosed with PD, in comparison with a sample of HC. Specifically, it distinguishes between dispositional and situational empathy, and examines the potential relationship between these two measures. Furthermore, the study analyses the relationship between these two empathy measures and specific cognitive processes, both in patients with cognitive decline and cognitively intact. The results show that cognitively impaired PD patients exhibit poorer situational empathy compared to the other groups. In contrast, no group differences emerge in dispositional empathy. No significant correlation is found between dispositional and situational empathy, nor are there consistent correlations between empathy and specific cognitive processes. These results warrant further in-depth analysis to better understand their implications.

Regarding situational empathy, the fact that significantly lower performance is observed in PD patients with cognitive decline suggests that this type of empathy may be more dependent on cognitive resources. In this sense, situational empathy refers to the ability to respond empathetically to specific, real-time social and emotional stimuli (Auné et al., 2015; Cuff et al., 2014; Fernández-Pinto et al., 2008). As such, it is inherently context-dependent and requires the rapid integration of multiple cognitive and affective processes. To successfully engage in situational empathy, individuals must dynamically interpret and respond to the emotional states of others, often based on subtle social cues such as facial expressions, tone of voice, body language, and situational context. This requires the involvement of a broad set of cognitive abilities, including attention, verbal memory, and executive control, among others. In PD patients, especially in patients experiencing cognitive decline, these cognitive processes can be impaired (Aarsland et al., 2021, 2017; Fang et al., 2020). Therefore, deficits in situational empathy observed in cognitively impaired PD patients may reflect the underlying deterioration of these higher-order cognitive functions (Alonso-Recio et al., 2021; Schmidt et al., 2017).

With regard to dispositional empathy, the fact that no impairments were observed in PD patients—regardless of whether they exhibited cognitive decline—suggests that this type of empathy may not be affected either by the disease itself or by the patient's cognitive status. This type of empathy refers to a stable and generalized tendency to respond empathetically in daily life and is typically assessed through self-report questionnaires that rely on introspective ability and an overall judgment of one's own behavior. The fact that PD patients, both with and without cognitive impairment, do not show differences compared to controls on this measure suggest that PD patients might maintain a relatively preserved perception of their own emotional responses. The presence of preserved dispositional empathy in PD patients has been confirmed by previous studies (see Alonso-Recio et al., 2021; Schwartz and Pell, 2017). However, the existing literature does not offer a unanimous consensus regarding this finding. Some studies have reported both generalized impairments (affecting affective and cognitive empathy) and specific deficits differentially impacting cognitive vs. affective empathy (Dodich et al., 2021; Martinez et al., 2018; Multani et al., 2019; Narme et al., 2013; Pomponi et al., 2016; Schmidt et al., 2017).

It is important to highlight that significant differences among the studies reviewed may account for the discrepancies observed in their results. For instance, some studies do not include a HC group, and instead evaluate dispositional empathy impairment by examining the proportion of patients scoring low on the administered measures (Dodich et al., 2021; Pomponi et al., 2016). Additionally, other research indicates that empathic deficits in PD patients are primarily evident in those at more advanced disease stages. Since our sample predominantly comprised patients in intermediate stages, the possibility that declines in empathic ability correlate with disease severity cannot be ruled out (Schmidt et al., 2017). Finally, in some studies, empathy assessments were conducted using informant-report measures completed by family members or caregivers, rather than relying on patients' self-reports. These recent findings are especially relevant when interpreting our results. In this regard, an alternative explanation for our results may be that the lack of group differences is not due to a preserved self-perception of emotional responses in PD patients, but rather to biases inherent in the self-report instrument. In this sense, informant-based evaluations can uncover empathic deficits that patients themselves may be unaware of or unable to accurately appraise, particularly in the presence of cognitive decline, which can impair self-awareness and metacognitive abilities. Consequently, the observed discrepancies between self-reported and informant-reported empathy underscore a key limitation of relying exclusively on self-report instruments. Caregiver or family member assessments may provide a more sensitive and objective measure of empathic functioning, capturing subtle or otherwise unrecognized impairments that are not reflected in patients' own evaluations. This suggests that a comprehensive assessment of situational empathy in PD should incorporate multiple perspectives to obtain a more accurate and nuanced understanding of empathic capacities.

In any case, the absence of a correlation between dispositional and situational measures serves to reinforce the notion that these phenomena represent discrete constructs, a notion that is in accordance with theoretical models that postulate a dissociation between the empathic trait (more closely associated with personality factors and exhibiting stability over time) and the empathic state (more dependent on context and the availability of cognitive resources) (Aparicio-Flores et al., 2020; Cuff et al., 2014). These models are supported by empirical studies showing that the specific empathic emotion experienced in a situation is not necessarily strongly related to one's dispositional tendency to empathize (Batson et al., 1987; Fabi et al., 2019). In healthy individuals, only a modest relationship between the two measures has been observed (Fabi et al., 2019; Zickfeld et al., 2017). Moreover, some neuroimaging studies suggest that brain activity related to empathy correlates more strongly with situational rather than dispositional empathy scores (Bufalari and Ionta, 2013; Lamm et al., 2011; Saarela et al., 2007; Singer et al., 2004). Therefore, assessing both situational and dispositional empathy together could offer a more complete insight into empathic abilities.

Finally, when the correlations between empathy tasks (situational and dispositional) and specific cognitive measures are analyzed, it is observed that, while dispositional empathy does not correlate with any cognitive measure, situational empathy does. However, in the latter case, we did not find any consistent relationship with any specific cognitive processes. A correlation was observed only between situational empathy and the verbal episodic memory task, and this was limited to healthy controls and PD patients with cognitive impairment, but was not present in cognitively preserved PD patients. This correlation could suggest that empathic ability depends, at least in part, on the ability to remember previous emotional interactions, given that those who perform better on the empathy task also tend to show higher verbal episodic memory performance, and vice versa. However, it is important to note that although PD patients with cognitive impairment perform worse than HC on the verbal episodic memory task, cognitively intact PD patients —who show preserved situational empathy—also display lower memory performance compared to HC, and do not significantly differ from cognitively impaired patients in this domain. Therefore, this isolated correlation is not sufficient to confirm that the reduction in situational empathy is driven by verbal memory decline.

The overall findings of the present study can be interpreted within the framework of the neurodegenerative changes that characterize PD, particularly; those that involve brain networks of social cognition and empathy. Dispositional empathy, being more closely related to stable traits, may rely more heavily on relatively preserved cortical structures in the early stages of PD (Kunst et al., 2019). Such structures include the medial prefrontal cortex and temporoparietal cortex, which are key regions of the default mode network. This network is involved in self-reflection, theory of mind, and stable social information processing (Frith and Frith, 2006; Spreng et al., 2009). Conversely, situational empathy entails real-time processing of social and affective cues, and this may be contingent on dynamic neural systems that facilitate the integration of emotional, perceptual, and cognitive information. These include the limbic system (e.g., the amygdala and the anterior cingulate gyrus), the anterior insula, and the orbitofrontal cortex, regions that undergo alterations in function and structure from the early stages of PD (Banwinkler et al., 2022; Conti et al., 2024; Criaud et al., 2016; Gleichgerrcht et al., 2010; Poletti et al., 2012; Wen et al., 2025). The progressive impairment of these regions by Lewy body accumulation, loss of mesocorticolimbic dopamine, and cholinergic dysfunction may provide a theoretical basis for the reduced situational empathic capacity in patients with cognitive impairment (Chaudhuri and Schapira, 2009).

Moreover, the results obtained in the present study suggest a close relationship between situational empathy (which assesses a purely affective component) and general cognitive processes, leading us to suggest a complex interplay between affective and general cognitive networks that are required in the generation of adaptive empathic responses. This supports the view of empathy as a distributed phenomenon in the brain, requiring the integration of multiple higher-order cognitive processes (Zaki and Ochsner, 2012). Different neuroimaging studies point to the insula, a structure that appears affected in PD and that has been linked both to motor and non-motor symptoms, as a key structure in the integration of cognitive and emotional processes (Criaud et al., 2016; Gu et al., 2013).

From a clinical perspective, these findings highlight the importance of conceptualizing SC as a distinct and clinically relevant domain, whose systematic assessment may complement and enhance traditional neuropsychological evaluations in PD. This is particularly relevant given that impairments within this domain can significantly affect patients' relational functioning and emotional wellbeing (Christidi et al., 2018; Trompeta et al., 2021). More specifically, the results underscore the need to assess empathy in its multiple dimensions, particularly, in PD patients with suspected cognitive decline. In these cases, the identification of a specific deficit in situational empathy in patients with cognitive impairment may serve as an early clinical indicator of social functional impairment. Such deficits can contribute to challenges in social communication, increased caregiver burden, and diminished overall quality of life. Patients with reduced situational empathy may struggle to interpret emotional cues during dynamic interactions, leading to miscommunication, and social withdrawal. This, in turn, can intensify feelings of loneliness and isolation—already prevalent among individuals with PD (Prell et al., 2023; Terracciano et al., 2023).

Taken together, these findings suggest that situational empathy tasks may be especially valuable in identifying subtle social-cognitive impairments that are not detected by self-report measures. Although dispositional scales provide important insights into relatively stable socio-cognitive traits, they may be less sensitive to the dynamic, context-dependent challenges that patients face in everyday interactions. Therefore, we propose that situational empathy tasks may complement traditional empathy assessments by offering greater ecological validity and capturing clinically relevant deficits. This could be particularly useful when assessing patients with suspected cognitive decline, where early detection of functional impairment is crucial. Moreover, the absence of significant group differences in self-reported empathy suggests that exclusive reliance on subjective instruments may lead to an overestimation of patients' empathic capacities in everyday contexts. Additionally, these findings highlight the need to develop targeted affective intervention programmes, which may be especially beneficial for patients with mild to moderate impairment—prior to the onset of more widespread functional decline. In light of the observed associations between situational empathy and specific cognitive domains, combined cognitive-affective interventions—such as cognitive stimulation protocols enriched with social-cognitive components—could offer a more integrated and effective therapeutic approach.

Limitations of the study include the sample size, which, despite the homogeneity of the groups, may have restricted the statistical power to detect more subtle relationships. Additionally, the use of a single task for each type of empathy limits the generalizability of the results. Another important limitation of our study concerns the operationalization of empathy components. While our assessment of dispositional empathy included both affective and cognitive dimensions, our situational empathy task focused exclusively on the affective component. This asymmetry restricts the scope of our conclusions regarding the full empathic profile of the participants. Further research could fruitfully explore the intersection of these definitional approaches—for example, by investigating whether deficits in situational empathy are primarily driven by impairments in cognitive, affective, or both dimensions, and whether these patterns vary according to patients' clinical characteristics. Such investigations could help refine our understanding of empathy as a multidimensional construct and guide more targeted clinical assessments and interventions. On the other hand, although the situational empathy task aimed to simulate realistic, everyday scenarios, it still falls short of fully capturing the complexity of real-life empathic experiences. Therefore, future studies should aim to develop and incorporate more ecologically valid contexts capable of eliciting genuine empathic responses. Future studies may also benefit from a multimodal approach, including neuropsychological tasks, physiological measures, and neuroimaging, to better understand the mechanisms underlying situational empathy in PD. Finally, subsequent research efforts could explore how situational and dispositional empathy manifest across the various stages of Parkinson's disease.
