Habenular Commissure Dysfunction

The habenular commissure is a tiny but significant part of the brain, responsible for regulating emotions and certain behaviors. Dysfunction in this area can lead to various issues affecting mental and emotional well-being. In this guide, we’ll explore what habenular commissure dysfunction entails, its types, causes, symptoms, diagnostic tests, treatments (both non-pharmacological and pharmacological), surgical options, prevention measures, and when it’s crucial to seek medical attention.

Types of Habenular Commissure Dysfunction

Habenular commissure dysfunction can manifest in different ways, including:

  1. Hyperactivity: Overstimulation of the habenular commissure leading to excessive emotional responses.
