More descriptions of akathisia: "The patient suffers from akathisia, an unbearable feeling of inner restlessness that manifests in movement. Whether the person shuffles the feet back and forth, or repeatedly rises and sits from the chair or paces in place, remaining immobile is nearly impossible. The symptoms may arise as a side effect of medications. Neuroleptic antipsychotics (the major tranquilizers)…are known to bring about the problem. People with Parkinson’s disease, and Huntington’s disease may suffer with the condition.
The patient describes rage, feeling like he must fight against the world. He doesn’t want to meet people for lunch, go for a walk, leave the house or exercise. He feels he constantly maintains equilibrium by practicing anger management. He gets no relief, and he states he’s worn down by the constant agitation, anxiety and feeling of coldness. Whatever the physician has tried is not working. He needs a new solution as fast as possible…The muscles of your jawbone go berserk, so that you bite the inside of your mouth and your jaw locks and the pain throbs. For hours every day this will occur. Your spinal column stiffens so that you can hardly move your head or your neck and sometimes your back bends like a bow and you cannot stand up. The pain grinds into your fiber … You ache with restlessness, so you feel you have to walk, to pace. And then as soon as you start pacing, the opposite occurs to you; you must sit and rest. Back and forth, up and down you go in pain you cannot locate, in such wretched anxiety you are overwhelmed, because you cannot get relief even in breathing. Jack Henry Abbot, In the Belly of the Beast (1981/1991)."
“Akathisia is another common EPS. 32, 46, 53-55 Akathisia is distinct in being defined by subjective as well as objective features, more often affecting the lower extremities, remaining a problem even with SGAs, and being less responsive to treatment. Subjectively, patients complain of inner tension, restlessness, anxiety, urge to move and inability to sit still, and drawing sensations in the legs. Observable motor features are complex, semi-purposeful and repetitive, including foot shuffling or tapping, shifting of weight, rocking, pacing incessantly and even running. Although the severity of these sensations varies with stress and arousal, they can become intolerable and have been associated with violence and suicide. 53, 55” From: Movement Disorders Induced by Antipsychotic Drugs: Implications of the CATIE Schizophrenia Trial.
