Background, about a year ago, my father-in-law who is 62 years old, suffered from severe panic attacks and depression that landed him in the phych ward twice. He would hyperventilate and tremble to the point that he could not function for hours at a time. Although he could stop the symptoms when his mind was not on the thing that we agreed was causing the panic attacks. The doctors in the ward treated him with several medications including Prozac and eventually Abilify and Respridol and those types of Anti-psychotics. I'm not sure why they gave him the anti-psychotics but they did. With drug and behavioral therapy, He finally improved to the point where and they sent him home after about 3 weeks the second time he was in. He was getting back to a normal life until he started exhibiting an even more bizarre behavior.
He is now suffering from a condition that is causing sever shaking and constant movement in his legs. It is so bad that he can barely walk. Now he can't stop the behavior no matter how hard he tries. He is so debilitated that he can not even stand for enough time to make himself a sandwich to eat so he is now depending on others to prepare his food. After he walks, well, shuffles he has to get down on all fours and crawl around in a vain attempt to stop the shaking and trembling. He is completely lucent during this. You can ask him questions and he responds, however he doesn't keep a conversation. He does not feel depressed but is debilitated enough to want to not go on.
The psychiatrist has taken him off the Abilify and he is no longer on anti psychotics but is still on prozac.
Can this be a severe form of TD or Akathesia caused by the drugs? If so please tell me there is hope. If not, what the heck could this be.
