PTSD, TBI, and MDD can all impact decision making and lead to risky behaviors. PTSD may cause aggression, numbness, and lack of care. TBI can impair decision making and emotional processing. MDD can cause feelings of worthlessness and hopelessness. Having multiple conditions makes resisting risky impulses even harder. To reduce risk, identify goals, strategies, and specific tactics like avoiding triggers and using healthy coping skills like journaling or relaxation. Learning about oneself helps recognize unsafe choices and change behaviors to stay safe.
