PTSD (post-traumatic stress disorder) is the psychological condition most commonly linked to stress among the options you listed. Reasoning and key points:
- Stress can trigger or exacerbate PTSD symptoms, especially after exposure to a traumatic event. PTSD encompasses intrusive memories, avoidance, negative changes in thinking and mood, and hyperarousal, and symptoms may intensify under stress. This aligns with clinical descriptions of PTSD and how stress interacts with trauma-related symptoms.
- Increased blood pressure and irritability can occur as part of the physiological and emotional arousal seen in PTSD, though elevated blood pressure is not a standalone diagnostic criterion for PTSD. It is listed among possible stress responses and is documented as part of PTSD symptomatology in patient resources.
- The other options:
- Increased blood pressure alone is a physiological response, not a standalone psychological condition.
- Schizophrenia is a distinct psychiatric disorder with multifactorial etiology, not a direct result of stress in the sense of a stress-induced condition.
- Unusual irritability is a symptom that can occur with several conditions, including PTSD or anxiety, but it is not itself a separate psychological condition.
- Post-traumatic stress disorder is the well-established connection between stress exposure and a lasting psychological condition.
Direct answer:
Post-traumatic stress disorder (PTSD) is the psychological condition most
commonly associated with stress among the listed options.
