Definition: Tangentiality is a communication disorder characterized by speech that lacks coherence and wanders off-topic, resulting in difficulty maintaining a logical and meaningful conversation. Individuals with tangentiality often struggle to maintain a clear train of thought and frequently digress into unrelated topics.


  • Psychiatric conditions: Tangentiality is commonly associated with certain psychiatric disorders, such as schizophrenia, bipolar disorder, and schizoaffective disorder.
  • Brain injuries: Damage to the frontal lobe, which is responsible for organizing and planning speech, may lead to tangentiality.
  • Neurodevelopmental disorders: Conditions like attention deficit hyperactivity disorder (ADHD) or autism spectrum disorders can contribute to tangentiality.


  • Excessive diversion from the main topic
  • Difficulty staying on track during conversations
  • Frequent interruption or disruption of others
  • Inability to provide relevant and concise responses
  • Lack of coherence in speech


  • Therapy: Speech and language therapy sessions can help individuals with tangentiality improve their communication skills and stay focused during conversations.
  • Medication: In cases where tangentiality is caused by an underlying psychiatric disorder, medications, such as antipsychotics or mood stabilizers, may be prescribed to manage symptoms.
  • Support groups: Participating in support groups with individuals who have similar communication challenges can provide emotional support and practical strategies for coping with tangentiality.

Conclusion: Tangentiality is a communication disorder that results in fragmented and digressive speech. Seeking professional help and implementing appropriate interventions can significantly improve an individual’s ability to engage in more coherent and meaningful conversations.
