A new study, published in the journal Stroke, linked an increased prevalence of post-traumatic stress disorder (PTSD) with a type of stroke called the transient ischemic attack (TIA).  With a TIA, the patient suffers temporary neurological symptoms, but does not have any lasting physical symptoms after the attack.  Suffering a TIA may be a traumatizing experience, leaving the patient at risk for PTSD and other adverse psychosocial outcomes.

The National Institute of Neurological Disorders and Stroke (NINDS) describes TIA as a transient stroke that lasts only a few minutes. It occurs when the blood supply to part of the brain is briefly interrupted. TIA symptoms, which usually occur suddenly, are similar to those of stroke but do not last as long. Most symptoms of a TIA disappear within an hour, although they may persist for up to 24 hours.

According to WebMD, the TIA is also known as a “mini-stroke” and affects five out of 1,000 people at some point in their life.  The TIA can be a warning sign for a person’s risk of stroke.  The study revealed that 14 percent of participants had significantly reduced mental quality of life after their mini-stroke.  Those who suffered mini-strokes also demonstrated symptoms of PTSD, including depression, anxiety, and reduced quality of life.

PTSD can develop when a person experiences a frightening event that poses a serious threat.  As a result, the person suffers from worry, flashbacks, nightmares, and social isolation.  In general, the study found that younger patients and patients who have a greater difficulty coping with stress had the highest risk of subsequent psychological problems.  Those who overestimate their risk of suffering a future stroke are also more likely to have lasting adverse impacts.
