Explain why failing to specifically recognise akathisia as a medication effect, rather than as anxiety or worsening illness, can lead to a genuinely harmful clinical error.

Akathisia can closely resemble anxiety or a worsening of the underlying psychiatric condition, particularly when its subjective component of inner restlessness and unease is prominent and its visible movement is relatively subtle. If a clinician attributes this presentation to anxiety or clinical deterioration rather than to the antipsychotic itself, the instinctive response is often to increase the dose of the very medication causing the problem, which will typically worsen the akathisia rather than improve it. Recognising the clear temporal link to starting or increasing the antipsychotic, and the specific quality of restlessness involved, is what allows the correct response — reducing or changing the causative medication — rather than a response that compounds the harm.
