What Is A Mood Disorder?

Mood disorders are a group of mental health conditions that affect a person’s emotional state, leading to persistent changes in mood that interfere with daily life. Common mood disorders include major depressive disorder, bipolar disorder, and seasonal affective disorder. Symptoms can include sadness, hopelessness, loss of interest in activities, changes in appetite or sleep patterns, irritability, and fatigue. These conditions can be caused by a variety of factors, including genetics, brain chemistry, and life events. Treatment options for mood disorders include therapy, medication, and lifestyle changes.

Signs & Symptoms Of Mood Disorders

The signs and symptoms of a mood disorder can vary depending on the specific condition, but some common symptoms include:

  • Persistent feelings of sadness, hopelessness, or emptiness.
  • Loss of interest or pleasure in activities that were once enjoyable.
  • Difficulty sleeping or excessive sleeping.
  • Changes in appetite or weight.
  • Fatigue or lack of energy.
  • Difficulty concentrating or making decisions.
  • Feelings of worthlessness or guilt.
  • Irritability or restlessness.
  • Thoughts of self-harm or suicide.

It’s important to note that everyone experiences emotions differently, and experiencing one or more of these symptoms does not necessarily mean that someone has a mood disorder. However, if these symptoms persist and interfere with daily functioning, it may be helpful to seek the advice of a mental health professional for proper diagnosis and treatment.

Ketamine for treatment of mood disorders and suicidality: A narrative review of recent progress

Faster-acting and more effective antidepressant medications are needed. Four decades of research has transformed the use of ketamine from an anesthetic to an outpatient treatment for major depressive disorder (MDD). Ketamine is a N-methyl-d-aspartate (NMDA) receptor antagonist and has been shown to rapidly improve mood symptoms and suicidal ideation by targeting the glutamate system directly. 1
