What is akathisia and how to treat it?

People with akathisia are restless, have a compulsion to keep moving, and are unable to stay still.  They may fidget, cross and uncross their legs repetitively, or constantly walk around.  The movement disorder is associated with certain types of medications such as antipsychotics as well as some medical conditions, like Parkinson’s disease.  While there is no specific treatment for akathisia, if medication-induced, changing the medication or lowering the dose may relieve symptoms.  Beta-blockers and sedatives may also help.
