Resolution of hyperacusis associated with depression, following lithium administration and directive counselling.
BACKGROUND
Hyperacusis may be described as a decreased threshold for discomfort from sound. It may have a serious impact on an individual's lifestyle, as a result of decreased sociability and inability to spend time with family and friends due to intolerance of sound.


METHODS
We present a case of hyperacusis associated with depression, with no other audiological abnormality. The patient reported greater difficulty during the depressive episode.


METHODS
Audiological investigation was undertaken, followed by counselling and medication for depression.


CONCLUSIONS
The pathophysiological mechanism of hyperacusis in depression is discussed. Outcomes following treatment with directive counselling and lithium (an antidepressant) are described. Research indicates that both hyperacusis and depression can be caused by hypoactivity of 5-hydroxytryptamine (also known as serotonin) in the brain. The patient reported improvement which cannot be explained solely on the basis of counselling. Enhancement of serotonin activity due to lithium, prescribed for depression, may also play a role in alleviation of hyperacusis.
