Key result
TIA and depression share a bidirectional link, with ~7% of TIA patients developing depression.
Why the study?
Prior research on cerebrovascular events and psychiatric disorders centered on stroke, leaving a lack of attention to a possible relationship between transient ischemic attacks and depression.
Is there a bidirectional relationship between transient ischemic attacks and depression?
Is there a bidirectional relationship between transient ischemic attacks and depression?
There appears to be a bidirectional relationship between transient ischemic attacks and depression, highlighting the need for clinical awareness of psychiatric comorbidities in cerebrovascular events.
Supports clinical awareness of TIA-depression links; leaves open prospective validation before changing practice.
BACKGROUND: An association between cerebrovascular events and psychiatric disorders has been reported. However, the focus has centered on stroke, and there has been a lack of attention to a possible relationship between transient ischemic attacks (TIAs) and depression. METHODS: We conducted a review of studies that looked specifically at the risk of depression after TIAs and the risk of TIAs in patients with depression. A total of 8 studies were identified, 4 examining the occurrence of depression following a TIA, and 4 examining the occurrence of TIAs after the onset of depression. RESULTS: There was a bidirectional effect: 3 of 4 studies showed an increased risk of TIAs in patients with depression, and 4 of 4 studies found an increase of depression following a TIA. The percentage of patients having a TIA from the pool of patients with depression was 3.18%. The percentage of patients who developed depression after a TIA in the pooled samples was 6.88%. CONCLUSIONS: Both depression and TIAs are serious medical disorders and they appear to have a bidirectional relationship. Further clinical and neurobiological studies in this area are warranted.

Kahlon et al. (2019) conducted a review in Transient Ischemic Attacks and Depression. Transient Ischemic Attacks and Depression was evaluated on Occurrence of depression following a TIA and occurrence of TIAs after the onset of depression. A bidirectional relationship exists between transient ischemic attacks and depression, with 3.18% of depressed patients having a TIA and 6.88% of TIA patients developing depression.
