Akathisia is a clinical term for extreme inner restlessness. People who are experiencing akathisia have great difficulty sitting still, or maybe even sitting at all. I first experienced akathisia on Abilify (which I ultimately discontinued because it gave me a facial dyskinesia), and it continued to plague me as I tried different antipsychotics, such as Haldol. I found myself unable to do anything except to go outside, pacing back and forth and smoking cigarettes. Propranolol offered me some relief from the worst of it, but the effect eventually faded.
The medications that are most likely to cause extrapyramidal side effects (EPS) — including tardive dyskinesia — are also the most likely suspects for akathisia. In fact, you might even say akathisia is a type of EPS, even though it does not cause per se involuntary movements. Common suspects would include Haldol and probably also Abilify, which has much greater risk of EPS than we once believed.
It’s excruciating to live with akathisia, and yet most people have never even heard the term. A common descriptor is the feeling of “wanting to crawl out of your skin”.
I’ve had some trouble over the years differentiating between akathisia and hyperactivity associated with my ADHD. The main difference between these two scenarios is the cause, but when you’re on a regimen of multiple antipsychotics plus lithium plus stimulants plus benzodiazepines it becomes difficult to discern cause and effect. No doubt in my mind, at its worst akathisia feels worse and even more frustrating than ADHD — but what about those days where it’s just kind of there?
I’ve also experienced restless leg syndrome. Some scholars believe there is a link between RLS and akathisia — essentially, that akathisia is like RLS experienced during the day (as well as at night — akathisia has kept me awake many nights). I would say this is a pretty apt comparison.
When I first started propranolol, and was able to sit and rest for a few minutes for the first time in weeks. It was like getting your first pair of glasses, and realizing you can see clearly now. The relief was nearly immediate. Unfortunately, it faded somewhat over time. But I’ll remember that instant where it hit me, the moment I put on the glasses, forever. I hadn’t even realized how bad it was until then.
