Ch Shujaat, the other day, had hinted at going to ask about Hassan Nawaz Sharif's health, a move that could become a chance for meeting of both the leaders. A remarkable breakthrough is expected with regard to the unification of both the league factions, the sources said. Our Lahore Staff Reporter adds: Punjab Chief Minister and PML-N President Shahbaz Sharif will fly to London here on Tuesday (today) to inquire after his nephew Hassan Nawaz's, son of PML-N Patron-in-Chief Mian Muhammad Nawaz Sharif health. Nawaz Sharif has already in London in connection with the medical treatment of his son. It is to be noted that Hassan Nawaz was diagnosed as having multiple sclerosis in 2005. Multiple sclerosis (MS) is a chronic, long-term condition that affects the central nervous system, including the brain and spinal cord. It is an auto-immune disease, which means that the body's immune system mistakenly attacks itself, targeting the cells, tissues, and organs. Scientists now believe that MS results from an abnormal response to an infection or an environmental factor. Numerous studies show that genetics may play a role in the development of MS, but are not the sole cause of the disease. MS affects over 2.4 million people worldwide. This disease is not uncommon in Western countries and most victims are young people aged from 20 to 30 years. It is treatable and curable and is not as life threatening. After treatment, a patient normally recovered within a reasonable span of time and resumed his or her life as a normal healthy human being.
