New Insight into Correlation Among Convergence Insufficiency, Vestibular Abnormalities and Depression in Post-Concussion Syndrome

Concussion and post-concussion syndrome (PCS) cause visual symptoms, including blurred- and double-vision those are partly caused by convergence insufficiency (CI). Depression is also a common complication in PCS. Several studies have suggested that depression recovery in concussion is in tandem with other symptoms. Depressed patients are less motivated and have a tendency to exaggerate their physical and cognitive deficiencies. We studied the correlation between CI and depression, in concussion and vestibular system for the first time. Our findings are interesting and in contrast to the current findings in the literature.
