Associative Looseness · What Is It, Diagnosis, and More

Associative looseness, also known as looseness of association or derailment, refers to a thought-process disorder characterized by disorganized speech due to a lack of connection between ideas. With associative looseness, ideas can be vaguely related to one another or completely unrelated, resulting in speech that is confusing and difficult to understand. Most often, associative looseness presents with a slow, steady loss of coherence, as the speaker’s thoughts become more disconnected with each sentence. 

Diagnosis of associative looseness is based on a psychological evaluation, which is a structured interview with a mental health professional that provides information to assess the individual's behavior, personality, thought processes, and cognitive abilities and identify any disturbances. 

Since associative looseness usually presents in the course of a psychotic disorder, such as schizophrenia, treating the underlying disorder may help improve the associative looseness. Treatment of schizophrenia varies from person to person, but it generally includes a combination of antipsychotic medications (e.g., olanzapine, clozapine, risperidone, quetiapine) and long-term psychotherapy, or talk therapy.
