Delirium

Two years ago, I went back to visit my parents and sibling on Malaysia. My sister bought a new apartment in the urban city. The size of the apartment is one-third size of my old hometown terrace house in rural area. My sister assigned some construction workers to decorate the interior of her new house, and badly that the paint was sit on the surface of concrete floor. It was completely messy and we need to remove the stain in those few days. I was too much plate on my hand to rip the stains off from the ground and was not talking to my father too much. However, he was happy and sat beside us but giving us a long rambling speech.

He said that he did not want to move to new house, he would like to stay at old house until his death. He was struggling to move far from the area with being acquaintance for almost 50 years already. Unfortunately, how hard he was rejected, was my sister the various method pursuing him with relentless energy. Finally, he was forced to live there after I left my home for several days. On those days, our family dog has disappeared when my family travelling for few days. My father almost lost his sense of happiness ever since those days.
For this two years, he always trapped in a small living room and sleeping beside my mother’s. They are fighting against each other continuing in an extreme way every day. Sometimes, yelling, screaming and cursing each to die. It was very normal and we were trying to ignore this subtle problem as we were busy working and had not enough time to meddle their difficult and complicated feelings. I felt fortunate that my brother back home for this two years as he could not travel to anywhere or working overseas. Even though my mother and my sister always blamed about his ignorance, but I still could feel his responsibility when somebody needs help.
The fact that, if my mother appeared and scolding at him. He started beating my mother and knocking her door badly. Everything were thrown everywhere and random violence occurred in some complicated manners.  My older brother has been beaten hardly with a chair at midnight. Doors broken, fling goods away from home to balcony or gallery. His mental and behaviour has been changed rapidly and becomes more irritated or restless especially at midnight.
My brothers immediately sent him to the public hospital with putting a lot of energy. He was sedated after given a drug to calm him down and make him sleep. Psychiatric doctor checked his head with CT scans and suspected he may develop delirium but still need neurologist to judge it in detail.
