Types of Excessive Talking
(snip)
Disorganized speech: This occurs when thoughts do not connect, causing speech to shift from one thought to another without coherence. Common with schizophrenia and other forms of psychosis, disorganized speech may involve neologisms (made-up words) and echolalia (repeating what someone just said to you).1112

Key Takeaways
Excessive talking occurs when a person talks compulsively, inappropriately, or more than what is outside social norms.
What is excessive might be regarded as subjective or simply a personality trait—but it might also be caused by mental illness or a neurodevelopmental or personality disorder. These include autism, attention-deficit/hyperactivity disorder, social anxiety disorder, and schizophrenia.
There are things you can do to avoid overtalking, like setting a mental timer, paying attention to social cues, or seeking the help of a mental health provider.

Schizophrenia involves a range of problems in how people think, feel and behave. Symptoms may include:
* Delusions. This is when people believe in things that aren't real or true. For example, people with schizophrenia could think that they're being harmed or harassed when they aren't. They could think that they're the target for certain gestures or comments when they aren't. They may think they're very famous or have great ability when that's not the case. Or they could feel that a major disaster is about to occur when that's not true. Most people with schizophrenia have delusions.

* Disorganized speech and thinking. Disorganized speech causes disorganized thinking. It can be hard for people with schizophrenia to talk with other people. The answers people with schizophrenia give to questions may not be related to what's being asked. Or questions may not be answered fully. Rarely, speech may include putting together unrelated words in a way that can't be understood. Sometimes this is called word salad.
* Extremely disorganized or unusual motor behavior. This may show in several ways, from childlike silliness to being agitated for no reason. Behavior isn't focused on a goal, so it's hard to do tasks. People with schizophrenia may not want to follow instructions. They may move in ways that are not typical or not appropriate to the social setting. Or they may not move much or respond at all.
