Anendophasia

Anendophasia is a new term researchers use to describe the absence or near-absence of an inner voice. An inner voice is the self-talk many people have when they think. Instead of words, you may think in pictures or ideas without using language.

Research shows that how often people experience an inner voice varies a lot. It’s not yet clear whether some people have no inner voice at all.

Anendophasia is just a different way of thinking. It isn’t a problem or anything to worry about unless it happens suddenly, like after a head injury or stroke.

How do people with anendophasia think?

While your thinking style is a little different, you still have a full inner world. It doesn’t affect your ability to remember information and solve problems, but it may make certain situations more challenging.

Here are some common ways you may think:

• You may think in pictures, visual scenes or mental images instead of sentences.
• You might “see” words in your mind like text on a screen rather than hear a voice say them.
• You may have strong feelings or ideas, but those don’t turn into words in your mind.
• You know what you’re thinking without explaining it to yourself.

What does anendophasia feel like?

If you have anendophasia, your mind may feel quiet because you don’t hear words or sentences when you think. There isn’t a running voice commenting on what you’re doing.

You might not be aware that you have anendophasia. Many people only realize it when they learn that others hear constant self-talk in their heads.

Daily life can still feel normal. You can plan, reason and understand conversations. You just don’t “talk things through” in your mind the way others do.

Because there are no outward signs, others can’t tell you think this way. For many people, learning about anendophasia simply helps explain why their inner experience feels different from what others describe.

Does anendophasia affect memory and problem-solving?

Not having inner speech may slow you down on tasks that depend on words. But it doesn’t limit your intelligence or reasoning. Some tasks may feel more challenging, like:

• Word-based memory: You may have a harder time holding words in your mind for a short time, like when you try to remember a list.
• Language-based tasks: You may find tasks like judging rhymes or talking through a word problem more difficult.

You can still solve problems and remember information in many other ways. This is especially true for tasks that use visual or nonverbal thinking. You might rely more on visual imagery, written notes, patterns or step-by-step planning instead of inner speech.

What causes anendophasia?

The exact reason there’s a difference in how often people experience an inner voice is unknown. Researchers believe it relates to how your brain is wired.

It’s not clear if your brain produces less inner speech or if you think in other ways and don’t experience inner speech the same way. Researchers continue to study why this happens.

How is anendophasia diagnosed?

Healthcare providers don’t diagnose anendophasia, and it’s not a medical diagnosis. Researchers may identify it by asking you questions about how you think and what your experiences feel like.

You may answer questionnaires or complete simple tasks. These often involve things that trigger inner speech, like rhyming words or remembering a list. Your responses help them better understand how your mind works.

Anendophasia treatment

Treatment isn’t usually necessary. If it makes certain tasks harder, you might try simple thinking strategies to help you use other strengths. These may include using visual imagery or speaking out loud to support your memory when needed.

Here’s an example. You’re trying to remember directions to the park. Someone tells you to go to the corner of Main and Third Street, then turn left at the red building. Instead of repeating these words in your head, you picture the street signs for Main and Third Street. You also picture a red building. You may also say these directions out loud to reinforce the memory.

When should anendophasia be treated by a healthcare provider?

You should see a healthcare provider if the loss of your inner voice happens suddenly. This is especially important if it occurs after a head injury or a stroke. In these cases, it could be a sign of aphasia (a condition that affects language and communication).

A healthcare provider can check what’s causing the change and help you manage any related symptoms.
