A lack of empathy doesn’t have a single clinical name. Instead, it shows up across several recognized conditions, each with a different pattern. The broadest terms you’ll encounter are “empathy deficit” in psychology literature and “alexithymia” when the core issue is difficulty recognizing emotions at all. But reduced empathy is also a defining feature of specific personality disorders, including narcissistic personality disorder and antisocial personality disorder, and it appears in a distinct way in autism spectrum conditions.
Which term fits depends on what’s actually happening beneath the surface, because empathy isn’t one skill. It’s at least two, and they can break down independently.
Two Kinds of Empathy, Two Ways They Fail
Cognitive empathy is the ability to understand what another person is thinking or feeling. It’s perspective-taking: you can figure out that your friend is upset about a job loss even if you’ve never lost a job yourself. Emotional empathy (sometimes called affective empathy) is the visceral, automatic part. Your body actually mirrors someone else’s experience. You see someone cry and feel a tightness in your own chest, or you watch someone get embarrassed and your own face flushes.
These two systems rely on different brain networks. Cognitive empathy depends heavily on the medial prefrontal cortex, a region involved in thinking about other people’s mental states. Emotional empathy draws more on the insula and the anterior cingulate cortex, areas that process bodily sensations and emotional pain. Damage or differences in one network can leave the other intact, which is why a person can seem perfectly capable of reading a room yet feel nothing when someone is suffering, or vice versa.
Alexithymia: No Words for Feelings
Alexithymia literally translates from Greek as “a lack of words for emotions.” It describes people who struggle to identify, describe, and process their own emotional states. If you can’t register what you’re feeling, it becomes much harder to recognize or share what someone else is feeling.
People with alexithymia often have trouble connecting bodily sensations to emotions. They might notice a racing heart without linking it to anxiety, or feel a knot in their stomach without recognizing it as grief. Their thinking tends to focus outward on facts and events rather than inward on emotional experience. About 10% of the general population meets the threshold for alexithymia, with men (roughly 12%) somewhat more likely to qualify than women (about 8%). It’s not a formal psychiatric diagnosis on its own but a trait that exists on a spectrum and frequently co-occurs with other conditions, including depression, PTSD, and autism.
Narcissistic Personality Disorder
Narcissistic personality disorder (NPD) is one of the conditions most associated with a lack of empathy in popular culture, and the clinical picture is more nuanced than “they don’t care.” People with NPD typically retain cognitive empathy. They can read a room, pick up on what others are feeling, and use that information strategically. What’s impaired is the emotional side: they don’t share in the feeling or generate a compassionate response to someone else’s pain.
Research published in Frontiers in Psychiatry describes this as empathy that is not insufficient so much as inefficient, heavily influenced by motivation and context. When someone with NPD feels confident and unthreatened, their empathic skills may function reasonably well. When they feel exposed or challenged, those skills drop off sharply. The pattern also tracks with narcissistic rivalry, a competitive orientation toward others, which predicts not just a failure to recognize someone else’s feelings but sometimes contradictory emotional responses, like satisfaction at another person’s distress. Researchers call this “affective dissonance.”
Antisocial Personality Disorder and Psychopathy
Antisocial personality disorder (ASPD) involves a more pervasive empathy impairment. The DSM-5 lists indifference to the feelings, needs, or suffering of others and an absence of remorse after hurting someone as key diagnostic criteria. Where NPD involves empathy that fluctuates with the person’s ego, ASPD involves a more consistent disengagement from others’ emotional experiences.
Psychopathy, which overlaps with ASPD but is measured separately, adds a specific twist. People with psychopathic traits can often perceive emotions in others accurately, yet the perception doesn’t trigger the automatic emotional resonance most people experience. Brain imaging studies link this to differences in the orbitofrontal cortex, which appears to play a key role in affective empathy. People with damage to this area, or with psychopathic traits, tend to fail affective empathy tasks while performing normally on cognitive ones. In some cases, they experience what researchers call “contrast empathy,” feeling pleasure or excitement in situations that would produce compassion or concern in most people.
Empathy and Autism: A Different Pattern
Autism spectrum conditions (ASC) affect empathy in a way that’s frequently misunderstood. A large meta-analysis in Frontiers in Psychology found that autistic individuals show measurable difficulty with cognitive empathy, the perspective-taking side, and with empathic concern, the compassionate response to someone in distress. However, their ability to accurately identify what emotion someone else is experiencing, when tested in real time, remains intact. In fact, on self-report measures, autistic people scored higher than neurotypical individuals on empathic accuracy.
What this means in practical terms is that many autistic people feel emotions intensely, sometimes more intensely than average, but have difficulty with the initial step of reading social cues and figuring out what someone else is experiencing. Once they do understand, the emotional response is often fully present. This is essentially the opposite of the narcissistic pattern, where reading people comes easily but the emotional follow-through is missing. Alexithymia co-occurs at high rates with autism, which further complicates the picture: someone may feel a strong emotional response but be unable to identify or communicate it, which can look from the outside like indifference.
What Shapes Empathy in the Brain
The brain’s core empathy network includes the anterior cingulate cortex, the middle cingulate cortex, and the insula on both sides. These regions activate consistently during tasks that require feeling what someone else feels, especially in response to others’ pain. The medial prefrontal cortex handles the more reflective, theory-of-mind component, helping you model another person’s perspective and regulate your emotional response based on context.
The volume of the insula correlates with how strongly people experience personal distress and empathic concern in response to others. The left amygdala appears to be a shared substrate for both alexithymia and empathy impairment, acting as a junction point where difficulty processing your own emotions and difficulty processing others’ emotions overlap. This neurological connection helps explain why alexithymia and low empathy so often travel together.
Can Empathy Be Improved?
Empathy is partly dispositional, shaped by genetics and brain structure, but it’s also partly a skill that responds to practice. Structured empathy education programs, like the Activating Empathy Program developed through a collaboration between Penn State and the National University of Ireland Galway, use guided group exercises over repeated sessions to help people practice perspective-taking, recognize the link between empathy and relationships, and build prosocial habits. These programs are designed primarily for young people and focus on activating empathy skills that may be underdeveloped rather than absent.
For clinical populations, therapeutic approaches vary by condition. Mentalization-based therapy helps people build the capacity to understand their own and others’ mental states, a skill that’s central to cognitive empathy. For alexithymia, therapy often focuses first on the foundational step of learning to notice and label one’s own emotions before attempting to engage with others’. The degree of improvement depends heavily on the underlying condition. Empathy deficits rooted in personality disorders are generally harder to shift than those linked to alexithymia or autism, where the emotional capacity is often present but the processing pathway needs support.
