The term "nervous breakdown" is sometimes used by people to describe a stressful situation in which they're temporarily unable to function normally in day-to-day life. It's commonly understood to occur when life's demands become physically and emotionally overwhelming. The term was frequently used in the past to cover a variety of mental disorders, but it's no longer used by mental health professionals today.
Nervous breakdown isn't a medical term, nor does it indicate a specific mental illness. But that doesn't mean it's a normal or a healthy response to stress. What some people call a nervous breakdown may indicate an underlying mental health problem that needs attention, such as depression or anxiety.
Signs of a so-called nervous breakdown vary from person to person and depend on the underlying cause. Exactly what constitutes a nervous breakdown also varies from one culture to another. Generally, it's understood to mean that a person is no longer able to function normally. For example, he or she may:
A number of other unusual or dysfunctional behaviors may be considered signs and symptoms of a nervous breakdown.
If you feel that you're experiencing a nervous breakdown, get help. If you have a primary care provider, talk to him or her about your signs and symptoms or seek help from a mental health professional.
