For many autistic people, being asked “How do you feel?” can be surprisingly difficult to answer. It’s not that they don’t have feelings. Often they feel emotions very deeply. But there can be a disconnect between experiencing an emotion and knowing how to identify or describe it in words.
This experience is known as alexithymia, a term literally meaning “no words for emotion.”
Alexithymia refers to difficulty recognizing and articulating one’s own feelings, and it is common among autistic people.
Research indicates that around half of autistic individuals have significant alexithymic traits, much higher than the general population. Estimates range from about 30% to 60%. It is not present in every autistic person.
Key Features
Alexithymia is not a formal disorder, but rather a trait characterized by difficulty in identifying and describing emotions.
In practical terms, a person with alexithymia often struggles to answer questions like “What are you feeling right now?”
They might feel the physical signs of an emotion, like a racing heart or a lump in the throat. Connecting those sensations to anxiety or sadness is harder.
Key features of alexithymia include:
- Difficulty recognizing feelings: Emotions may register as vague physical sensations or just a sense of being unwell, with little clarity on whether one is sad, anxious, angry, etc.
- Difficulty describing feelings: Even when an emotion is felt, putting it into words is challenging. One might say “I’m upset” without pinpointing whether it’s frustration, loneliness, or something else.
- Externally oriented thinking: There is a tendency to focus on external facts and events rather than inner emotional states, making self-reflection on feelings limited.
This trait exists on a spectrum: some people are mildly alexithymic, while others are strongly so.
Autism, Alexithymia, and Overlapping Challenges
How Common Is Alexithymia in Autism?
Alexithymia often co-occurs with autism. Researchers usually measure it with the 20-item Toronto Alexithymia Scale (Bagby et al., 1994), where a score of 61 or more is conventionally treated as alexithymic. That cut-off is a convention, not a diagnosis.
In the general population, 13% of 1,285 people surveyed in Finland scored in the alexithymic range (Salminen et al., 1999). In autistic samples, estimates range from about 30% to 60%, depending on the sample and the cut-off (Kinnaird et al., 2019; Oakley et al., 2022).
This overlap can shape how emotions are experienced, expressed, and understood.
The pattern differs by sex. In one large cohort, autistic women (47.3%) were more likely than autistic men (21.0%) to reach the cut-off (Oakley et al., 2022). That is the reverse of the general population, where men score higher (Salminen et al., 1999).
The Alexithymia Hypothesis
Researchers have proposed the alexithymia hypothesis (Bird & Cook, 2013). It suggests that many stereotypes about autistic individuals, such as low empathy or being “emotionally distant”, may be due to alexithymia rather than autism itself.
When an autistic person appears unaware of another’s feelings, it may be because they can’t readily identify their own. The same can be true when they don’t express their own emotions in expected ways. It does not mean they lack empathy or feel nothing.
“For those of us with alexithymia, we may know in a vague way that we’re distressed, but might not be able to name a specific feeling… We also struggle to figure out why we’re feeling [it].“
Autistic psychologist Dr. Devon Price
The evidence is mixed. Small matched studies support the idea, but a preregistered meta-analysis of 226 studies found no moderating effect of alexithymia on empathy (Cusson et al., 2025). Alexithymia explains part of the difference, not all of it.
The double empathy problem offers a complementary view: misunderstanding between autistic and non-autistic people runs both ways.
Why Alexithymia and Autism Overlap
One reason for this overlap is differences in interoception, the ability to sense internal body signals like heart rate or tension. If your body feels off but the signal is unclear, it’s harder to identify the emotion behind it.
The link is real but modest. A pooled analysis of 66 samples found it was small overall and depended on how interoception was measured (Trevisan et al., 2019).
Sensory experience may be involved too. A 2025 study of 207 pairs of adolescent twins suggested that alexithymia may explain the genetic link between autism and sensory sensitivity (Yorke et al., 2025).
Social learning may also play a role. Many autistic people are taught to mask emotions or prioritize others’ reactions, which could weaken emotional awareness over time.
Studies so far measure alexithymia and masking at one point in time, so none has tested it directly. It is a plausible hypothesis, not yet a finding.
Dr. Price notes that alexithymia may arise partly because autistic individuals aren’t given the tools to understand their own emotions. They are taught to prioritize others’ feelings or to hide their genuine responses. Over time, this can weaken the connection between what one feels and one’s awareness of it.
It’s important to note: not all autistic people have alexithymia. But for those who do, it can make emotional communication harder, both internally and with others.
How Alexithymia Feels: Autistic Perspectives
For autistic people with alexithymia, emotions are often intense but hard to name. Many describe feeling something deeply without knowing what it is.
“The worse I feel, the more I default to saying ‘I’m fine,’” one forum user shared.
Another said, “I know something’s wrong, but I don’t know what that something is.”
Emotional insight can come hours or days later. One person explained they often write to figure out how they feel:
“At first I say ‘I don’t know.’ Then later, I can explain it in paragraphs.”
These delays are often misunderstood. Loved ones may see “I don’t know” as avoidance, but for many, it’s an honest answer.
“My mum thought I was hiding something when I really didn’t know,” recalled one autistic woman.
This disconnect can strain relationships. Some feel pressure to fake or exaggerate emotions just to meet expectations.
“I used to think I was broken because I couldn’t express things like others,” one person admitted.
For many, alexithymia feels like emotional static: there’s a signal, but it’s hard to tune in. Understanding this can reduce shame and open up better ways to connect.
Common Challenges with Alexithymia in Autism
Alexithymia can affect many aspects of an autistic person’s daily life and mental health. Here are some common challenges that individuals and families may encounter:
- Anxiety and stress spikes: Feelings build up unnoticed until they feel overwhelming.
- Emotion regulation: Unnamed feelings are harder to calm, so meltdowns and shutdowns become more likely.
- Misunderstandings: “I don’t know” can be misread as avoidance or indifference.
- Relationship strain: Mismatched expectations can leave both partners feeling hurt.
- Mental health: Alexithymia often co-occurs with anxiety disorders and depression.
Anxiety and stress spikes
Because it’s hard to sense and label emotions in the moment, feelings like anxiety can build up unnoticed until they become overwhelming.
Physical symptoms (e.g., a racing heart or nausea) might be confusing and unpredictable, making the anxiety feel even worse.
An autistic person might suddenly have a panic reaction without earlier warning signs, simply because they couldn’t identify the subtle anxiety as it grew.
Research supports this. In autistic adolescents and young adults, difficulty identifying feelings predicted anxiety 12 to 24 months later (Oakley et al., 2022). The link held after accounting for core autistic traits. That does not prove cause, but it makes alexithymia a plausible target for support.
Emotion regulation difficulties
When you can’t pinpoint what you’re feeling, it’s tougher to calm yourself or seek help. Alexithymia can thus make emotional meltdowns or shutdowns more likely, because the feelings aren’t addressed until they “overflow.”
Autistic individuals with alexithymia may have a harder time regulating difficult emotions. Coping with stress can be harder too. Everyday worries may get brushed off, because distress that can’t be named is difficult to process. It is simply felt as an uncomfortable state.
Misunderstandings in communication
Loved ones and peers might misinterpret an autistic person’s emotional neutralness or “I don’t know” answers.
They may assume the person is indifferent, lying, or doesn’t trust them enough to share feelings. In reality, the person would share if they knew their own feelings!
This gap can cause frustration on both sides. For instance, the mother of the woman above felt her daughter was hiding something, when in fact she genuinely couldn’t identify her emotions at the time.
Research suggests that difficulty describing feelings is the facet most closely linked to self-reported social-communication difficulties. In one cohort, it also predicted those difficulties 12 to 24 months later (Oakley et al., 2022).
Strains on relationships
Beyond specific miscommunications, alexithymia can create a general mismatch of expectations.
A partner might expect emotional reassurance or enthusiastic responses that the alexithymic person simply doesn’t provide, possibly leading to the partner feeling unloved.
Likewise, the autistic individual may feel guilty for not meeting social “norms” of emotional expression.
Without understanding alexithymia, both parties might feel hurt. There can be an upside too. Some alexithymic individuals say they stay calmer during conflicts because they don’t get swept up in emotional tides as easily. But that calm can be misread as not caring.
Mental health implications
Alexithymia often co-occurs with conditions like anxiety disorders or depression. It can become a vicious cycle. Not understanding your own emotions can lead to internalized stress and isolation, which can in turn feed depression or heightened anxiety.
Studies have found that in autistic people, higher alexithymia is associated with more mental health challenges and even reduced quality of life.
Alexithymia also appears in other conditions, including ADHD. The table shows the pattern.
| Condition | Typical pattern | Best evidence |
|---|---|---|
| Autism | About 30% to 60% above the cut-off, depending on the sample | Meta-analysis, 15 studies (Kinnaird et al., 2019) |
| ADHD | From about a fifth to about two fifths above the cut-off | Individual studies only; no meta-analysis located |
| Post-traumatic stress | Large association with alexithymia | Meta-analysis, 12 studies (Frewen et al., 2008) |
| Depression | Medium association with difficulty identifying and describing feelings | Meta-analysis, 19 studies (Li et al., 2015) |
| Eating disorders | Higher scores than comparison groups in every diagnostic group | Meta-analysis, 44 studies (Westwood et al., 2017) |
These are associations only, so they cannot show which comes first.
Alexithymia may also contribute to autistic burnout. A systematic review of 48 studies identified it as one of several contributors (Ali et al., 2025). Participants said it made it “difficult to know when burnout is coming on.” That is reported experience, not proof of cause.
The good news is that recognizing and accommodating alexithymia can ease misunderstandings. Whether targeting it also improves mental well-being in autistic people has not yet been tested in controlled trials.
Coping Strategies and Support
Living with alexithymia can be confusing, especially when emotions feel overwhelming but hard to name.
While there’s no quick fix, many autistic people find ways to build emotional awareness and communicate more effectively over time.
Strengthen the Mind–Body Connection
Because alexithymia is closely tied to interoception (your ability to recognize internal bodily signals), improving body awareness is often a helpful first step.
Try these approaches:
- Mindfulness and body scans: Pause during the day to ask, “What is my body feeling right now?” Start with sensations like tension, heat, or movement before linking them to emotions.
- Breathwork or yoga: Gentle, structured movement can help you notice subtle internal changes.
- Interoception-based programs: Some therapies specifically target emotional awareness through sensory and body-focused exercises.
Over time, this practice helps make vague or physical feelings easier to name.
Use Journaling to Identify Emotions
For many autistic adults, writing is an effective tool for processing emotions.
One autistic person shared:
“At first I say ‘I don’t know.’ Then a few days later, I can explain everything in detail. I had to write it out to figure it out.”
If speaking in the moment feels difficult, try:
- Writing a few sentences a day about what happened and how your body reacted.
- Using prompts like “What made me feel different today?” or “When did I feel ‘off,’ and what was happening?”
Even brief notes can help you recognize emotional patterns over time.
Use Emotion Tools
Sometimes it’s not that you’re not feeling, but that the right words are missing. Visual or structured tools can help bridge this gap.
Consider:
- Emotion wheels with a wide range of words (e.g., agitated, hopeful, withdrawn).
- Feelings charts or emoji-based tools, especially for visual thinkers.
- Apps that help track moods and label feelings over time.
One person shared:
“I don’t find happy/sad/mad useful. I have a chart with more nuanced words—like drained or restless—and that helps me connect to what I’m actually feeling.”
Having language that fits your internal state can make it easier to express and regulate emotion.
Researchers also study how people group emotions. In a preregistered study, people less accurate at matching situations that evoke similar feelings, such as heights and predators, tended to report more alexithymia (Fiedler et al., 2025).
That task tests how people judge emotional similarity, not how they name their own feelings, so the link to daily life is not yet proven.
Seek Neurodiversity-Affirming Therapy
Therapy can support emotional understanding if it’s adapted to your needs. Some common approaches include:
- CBT (Cognitive Behavioral Therapy): Helps link thoughts, body signals, and reactions.
- DBT (Dialectical Behavior Therapy): Focuses on emotional regulation and mindfulness.
- Mentalization-based therapy: Builds awareness of your own and others’ emotional states.
The key is finding a therapist familiar with autism and alexithymia. They should be flexible, avoid pushing for instant emotional insight, and use concrete strategies that support self-reflection.
Research on autistic adults’ own experience supports this. In a survey of 269 autistic adults, greater alexithymia went with finding cognitive strategies, such as challenging thoughts, harder to use (Mazurek et al., 2026).
Interviews with 20 Australian autistic adults point the same way. One participant said, “It’s actually about the relationship that the therapist has built with me” (Browne et al., 2026).
Communicate Your Needs to Others
Let loved ones know that saying “I don’t know how I feel” is honest, not avoidance. You might agree on alternatives like:
- “Can I tell you later after I think about it?”
- “I’m not sure yet, but I think something’s off.”
Parents can also help children by:
- Using emotion cards or books to label feelings together.
- Validating confusion (“It’s okay not to know how you feel right away”).
- Avoiding pressure to respond emotionally on demand.
When others understand alexithymia, it reduces misunderstandings and emotional strain on both sides.
Creative outlets
Some people with alexithymia find that creative activities (art, music, writing poetry or lyrics) allow them to express emotions they can’t verbalize. The process of art can tap into feelings indirectly.
For example, sketching with intense colors when you’re restless, or making a playlist of songs that match your unspoken mood, can be ways of acknowledging emotions when words fail.
Later, you might reflect on why you chose those expressions, gradually connecting them to feelings.
Be Patient With Yourself
Alexithymia isn’t a flaw. It’s a different way of processing emotions. Progress can be slow and non-linear. What matters is building awareness over time.
One autistic adult put it simply:
“Alexithymia doesn’t mean I don’t feel. It just means I process those feelings differently—and that’s okay.”
Celebrate small wins. If you noticed a shift in mood earlier than usual, or managed to express even part of what you were feeling, that’s growth.
Evidence Check: How Well Does the Research Hold Up?
Verdict: Supported with qualifications.
Alexithymia is clearly more common in autistic people. Psychological treatment lowers scores on average. But the idea that alexithymia explains autistic differences in empathy and body awareness is contested.
The difference is large. A meta-analysis of 15 studies found a weighted prevalence of 49.93% in autistic groups against 4.89% in comparison groups (Kinnaird et al., 2019).
A separate cohort of 337 adolescents and adults found the same direction with a lower figure, 29.1% against 4.4% (Oakley et al., 2022). A review of eight studies of children and adolescents also found higher alexithymia in autistic young people (Vaiouli et al., 2022).
The direction is secure. The size is not. Estimates run from about 30% to 60%, and every study used the same self-report questionnaire. Autistic people with intellectual disability or little spoken language are largely absent.
The claim that alexithymia, rather than autism, explains differences in empathy and body awareness holds in some studies and fails in others. Small matched experiments support it.
In 18 autistic and 18 non-autistic men, empathy-related brain activity did not differ once alexithymia was accounted for (Bird et al., 2010). The same held for heartbeat tracking in 19 autistic and 19 comparison adults matched on alexithymia (Shah et al., 2016).
The largest test goes the other way.
A preregistered meta-analysis of 226 studies, with 13,278 autistic and 44,218 comparison participants, found no moderating effect of alexithymia on empathy (Cusson et al., 2025).
A pooled analysis of 66 samples found a small link between alexithymia and interoception (r = -.162; Trevisan et al., 2019). It was not significant in typically developing samples.
A preregistered study of 519 adults found that alexithymia alone accounted for diagnostic-group differences in self-reported interoceptive accuracy and attention (Adams et al., 2026). Even so, autistic traits still predicted all three dimensions with alexithymia controlled.
Each design has limits.
The small experiments test individuals but have few participants, and the heartbeat task is a contested measure. The meta-analysis is far larger but compares group-level scores, so it can miss an individual-level effect.
So the strong version, that autism adds nothing once alexithymia is considered, is not supported. The weaker version holds. Alexithymia explains part of the variation in emotion recognition, empathy-related brain responses and interoception, but it has not been shown to explain all autistic differences.
Psychological treatment lowers alexithymia scores on average.
A meta-analysis of four randomised trials of mindfulness-based interventions (460 participants) found lower scores than controls (mean difference -5.28 points, 95% CI -9.28 to -1.28; Norman et al., 2019).
A review of 18 randomised trials (21 arms, 1,251 participants) found that most psychological treatments reduced scores (Tsubaki & Shimizu, 2024). Results varied widely.
The trials are few and small, the outcome is a self-reported scale, and none was limited to autistic or ADHD samples. There are not yet controlled trials showing the same effect in autistic or ADHD adults.
Key Takeaways
- Definition: Alexithymia is a trait, not a diagnosis. It means difficulty identifying and describing your own feelings, and many people with it feel deeply.
- Autism Link: Alexithymia is considerably more common in autistic people, with estimates from about 30% to 60% depending on the sample. It is not present in every autistic person.
- Body Signals: Differences in interoception, the sense of internal signals like heart rate, can make feelings harder to name.
- Everyday Impact: Unnamed feelings can build up unnoticed. This can feed anxiety and lead to misunderstandings.
- Support: Body awareness, journaling, emotion-word tools and neurodiversity-affirming therapy can help. Trials in autistic adults are still lacking.
- Verdict: Supported with qualifications. Alexithymia is clearly more common in autistic people, but the claim that it explains all autistic differences is contested.
