Effective verbal communication is vital to our ability to connect with one another, get things done, and generally thrive as humans. So, it can be concerning when language (either yours or someone else’s) is marked by non-sequiturs, confusing phrasing, words that don’t exist, or similar abnormalities. These types of irregularities are known as disorganized speech, and are a common characteristic of schizophrenia and other mental health concerns.

Disorganized speech refers to verbal communication that is irregular and difficult to understand. Also called formal thought disorder, disorganized speech is a common characteristic of schizophrenia and other mental health concerns.

If you think you or a loved one may be experiencing disorganized speech, it can help to know how to recognize and respond to these challenges. Here, you’ll find an overview of disorganized speech, covering why it occurs, how it can manifest, and what you can do if you notice a loved one exhibiting signs of formal thought disorder.

What is disorganized speech?

According to the American Psychological Association, disorganized speech involves verbal discourse in which “ideas shift from one subject to another seemingly unrelated subject” and may also include responding to questions in an irrelevant way, reaching illogical conclusions, and making up words.

When you’re talking to someone who speaks in such a way, you may have trouble following their train of thought or predicting what they might say next. Also known as formal thought disorder, Disorganized speech is a primary characteristic of schizophrenia and is also associated with schizotypal personality disorder and autism spectrum disorder.  

Disorganized speech patterns can affect a person’s social skills, making it difficult for them to communicate effectively and engage in meaningful conversations. Additionally, to someone who is not familiar with disordered speech, the phenomenon can be alarming. There are different irregular verbal patterns that may be used by someone experiencing disorganized speech, several of which are listed below.

Loosening of associations in disorganized speech

Also called derailment, this phenomenon occurs when a person connects ideas or words that don’t seem to go together. They may quickly move from one idea to a concept that doesn’t seem to be related. For example, they might say something like, “I went to the store today. Soccer is a boring game. Grapefruit is too sour”. 

Tangential speech

Similar to forming loose associations, answering a question for someone with disorganized thinking may involve a non-sequitur. This is known as tangential speech. The answer might be vaguely related to the question, or it might not seem to be an answer to the question at all. For instance, if you asked a person with disorganized speech how they’re feeling today, they might answer by saying, “It’s cloudy outside”. 

Paralogism

Sometimes, disorganized speaking involves coming to a conclusion that is not based on reason. Paralogism is an unintentionally illogical assertion. For example, a person might say, “I heard a bird outside, so I know Friday is the last day of the month”. 

Neologism

A person with disorganized speech might make up a new word that does not relate to any established term. For example, they may call an orange a “tofuela”.

Disordered speech: “Word salad”

In some cases, a person might use both words and sentences that don’t bear any resemblance to ordinary speech. It may be difficult or even impossible to understand what they’re trying to say. This is often referred to as word salad.

Word approximations

Some people who display disorganized speech use words that make sense but are unconventional. They may, for example, call a hat a “head topper”. 

Echolalia 

An individual with formal thought disorder may repeat words that their conversation partner is using. For example, if you ask someone, “What time is it?” may be responded to with, “What time”, they may be engaging in echolalia. 

Causes of disorganized speech

While there is no unified theory explaining why formal thought disorder develops, several potential contributing factors have been identified. The following are potential causes and risk factors that have been connected with disorganized speech.

Alterations in brain function/structure related to schizophrenia

Structural changes and dysfunction in certain regions of the brain are considered a primary cause of disorganized speech. A meta-analysis of brain imaging studies found that brain activity in certain regions, including the prefrontal cortex and temporal lobes, is altered in those who have formal thought disorder. These significant alterations can lead to difficulties in organizing thoughts and expressing ideas coherently, which are hallmark features of disorganized speech.

Semantic memory impairment and its impact on mental health

People who have schizophrenia are thought to experience deficits in semantic memory. This term usually refers to the part of your long-term memory that deals with concepts and ideas outside the realm of your own experiences. It can include common knowledge, such as how to turn on a television or the names of state capitals. Alterations in semantic memory function can make it hard to develop the required network of connected words and concepts that facilitate effective communication. These impairments can contribute to difficulties in expressing thoughts clearly, impacting overall mental health and functioning.

Working memory impairment and its connection to formal thought disorder

Your working memory holds conscious, short-term thoughts. A crucial component of executive function, this type of memory helps us get and synthesize information, contributing to our ability to communicate. It is thought that people with formal thought disorder may experience working memory impairment. This impairment can impact the diagnosis and treatment of related mental health issues, including challenges in expressing coherent thoughts.

Genetic factors and their role in treatment for schizophrenia or delusions

Schizophrenia and similar conditions associated with disorganized speech are thought to have a strong genetic component. For example, one study linked schizophrenia and formal thought disorder to a mutation that affects a specific coding gene. Understanding these genetic factors can inform treatment approaches, particularly for individuals experiencing delusions.

Early experiences and their impact on the diagnosis of thought disorder

Some experts believe that the established connection between thought disorder and social functioning challenges can be partially explained by upbringing. Having parents who interpret the world in idiosyncratic ways may increase an individual’s risk of experiencing similar challenges.  This connection highlights the importance of considering early experiences in the diagnosis and treatment of an individual who may also experience delusions.

Symptoms and signs of schizophrenia & bipolar disorder

Because disorganized speech is one of the dominant characteristics of disorganized schizophrenia and bipolar disorder, it can help to know how to recognize other signs of these serious mental disorders.  (Previously, disorganized schizophrenia was considered a subtype of schizophrenia, but is now considered to be the same mental health condition.)

The following are some of the symptoms of schizophrenia:

  • Disorganized thinking and speech

  • Delusions (false beliefs not based on reality)

  • Hallucinations (seeing or hearing things that aren’t really there)

  • Childlike behavior

  • Agitation

  • Engaging in activities that aren’t focused on any goal

  • Resisting instructions

  • Sitting, standing, or laying in inappropriate positions

  • Unresponsiveness

  • Moving excessively

  • Neglecting personal hygiene

  • Lacking any signs of emotion

  • Loss of interest in daily activities

  • Disorganized behavior

  • Socially isolating

  • Inability to feel pleasure

Symptoms of bipolar disorder vary depending on whether the person is in a manic episode or depressive episode.

  • Elated or irritable vs sad or anxious

  • Jumpy or wired vs. slowed down or restless

  • Decreased need for sleep vs. sleep difficulties

  • Talking fast about many things vs. talking slow and forgetfulness

  • Racing thoughts vs lack of concentration

  • Endless energy vs listless

  • Indulging in excessive pleasurable activities vs hopelessness and suicidal thoughts.

How to respond to disorganized speech

It can be hard to know what to do when someone with whom you’re conversing displays signs of formal thought disorder. And it may be concerning if you are experiencing some of the types of disorganized speech listed above. If you or someone you know is experiencing symptoms of formal thought disorder, the following are some tips for addressing the situation. 

Seek help

One of the most important steps you can take when addressing formal thought disorder is to consult a mental health or medical provider. A healthcare professional can provide testing, diagnosis, and treatment. Often, treatment for schizophrenia and other conditions associated with disorganized speech consists of a combination of medication and therapy. 

While disorganized speech can be alarming, try to avoid trying to diagnose the problem yourself. What seems like disorganized speech may have a cause that is unrelated to a brain disorder. For instance, if a person quickly shifts from one subject to another, it might be that they are distracted easily or have a lot on their mind. If a person responds to a question with an answer that doesn’t have anything to do with what was asked, it might be that they’re attempting to avoid answering the question, not that they are experiencing disorganized speech. If you suspect that what you’re seeing is disorganized speech, it is typically best to get a professional opinion.Avoid parsing their speech

It might seem natural and constructive to point out irregularities in someone else’s verbal communication. However, it’s possible the person with whom you’re speaking might feel judged or criticized by this response. Instead, try to listen to what they’re saying in a respectful manner, even if you don’t understand it. You can respond to the ideas that have a logical basis and provide emotional support as you listen to those that might not.
