The presence and severity of<unk>  can be measured using the Barnes<unk>  Scale, which assesses both objective and subjective criteria. Precise assessment of<unk>  is problematic, as there are various types making it difficult to differentiate from disorders with similar symptoms. The primary distinguishing features of<unk>  in comparison with other syndromes are primarily subjective characteristics, such as the feeling of inner restlessness and tension.<unk>  can commonly be mistaken for agitation secondary to psychotic symptoms or mood disorder, antipsychotic dysphoria, restless legs syndrome, anxiety, insomnia, drug withdrawal states, tardive dyskinesia, or other neurological and medical conditions. The controversial diagnosis of "pseudoakathisia" is sometimes given.
