Risperidone-Induced Dysphagia?

I read your case report's abstract, Risperidone-Induced Balbar Palsy-like Synd
 rome, PMID:20922432.

My family member, 97, has had difficulty swallowing
  since the next day after admission to the Kobe Red Cross Hospital(May 18, 201
 2)due to cerebellar infarction.He got diapered and strapped to the bed for the
  first time. He surely had psychological trauma. The cerebellar infarction res ulted diagnosedly from March 12 falling resulting in facial contusion and internal bleeding. Since then till October 31, he had been given risperidone throu gh three hospitals. I asked the director of the third hospital to stop risperi done due to its side effects. And then, risperidone  was completely withdrawn.

According to pharmacists' association, sudden drug withdrawal might result in adverse effect, or retroaction.They recommended dose reduction after long-term medication. Amoban has still been given to him. The doctors here said dysphagia is due chiefly  to blood clot and age, and he won't get better. But at the third and fourth hospitals,  he takes foods for dysphagia  by mouth.

His symptons before admission are as follows:

 Aug.2010 one-eye cataract operation, Since then, unable to walk without a sti
 ck. neurologically nothing abnormal detected.

Aug. 2011 the other eye cataract operation, still unable to walk without a sti
 ck.

Apr.26 2012 instead of a few years long steroid external medication by a town
 doctor, resulting in internal bleeding and scrabbling,  Yokukansan and Alrock
 administered as a drink. after that, feeling sluggish.

May 9 tooth extraction

  every third day medication of sennoside by his town doctor

 of every after meal medication of a purgative by the surgeon after that, he fo
 llowed the surgeon.
