Why TBIs Deserve Immediate Attention

Many people don’t realize that mood disorders like depression, anxiety, or even relationship breakdowns—yes, including divorce—can stem from an undiagnosed or untreated TBI. The injury doesn't just affect the body; it affects the whole person and their relationships. 

The Link Between TBI and Intimacy Struggles

After a TBI, intimacy may be impacted—both emotionally and physically. Here’s why:

1. Physical Changes 

  • Chronic fatigue, pain, and hormonal imbalances can reduce libido. 
  • Physical discomfort makes intimacy more difficult.

2. Cognitive and Emotional Effects 

  • Memory loss, PTSD, or depression can interfere with sexual interest. 
  • Survivors may feel overwhelmed or confused by closeness. 

3. Self-Esteem and Body Image 

  • Scars, disabilities, and memory loss can reduce confidence. 
  • Fear of inadequacy can cause emotional withdrawal. 

4. Changing Roles in Relationships 

  • Caregiving shifts the dynamic, making romance feel distant. 
  • Open communication may become harder, deepening the disconnect. 

5. Medication Side Effects 

  • Painkillers, antidepressants, and other meds may impact sexual function. 


Healing takes time—and so does rebuilding intimacy. Support from professionals like therapists can help both partners navigate this journey.
