Parkinson's disease is rare for former President Bush

George HW Bush suffers from vascular Parkinson's - a rare form of this disease and affects the lower part of his body so that he cannot walk .

Former US President George HW Bush died on November 30 after nearly 8 months of hospitalization due to "infection spreading into the blood". He was admitted to the hospital just a day after his wife's funeral, Barbara Bush.

According to the AP, Bush has struggled with vascular Parkinson's for the past few years, affecting his lower body, making him unable to walk. Bush "father" had to use a wheelchair since losing his vertebra in 2015.

Dr Alberto J. Espay, professor of neurology at the University of Cincinnati, USA, said people with vascular Parkinson's do not have specific symptoms. They also did not respond to Parkinson's medicine.

According to the Parkinson's Foundation, the disease caused by a series of small strokes in the brain causes the body to slow down, tremor and stiffness. The patient is often affected in the lower body (from the waist down), so it is difficult to walk and maintain balance.

Bush "father" said in an interview with Parade magazine in 2012, that the condition was not painful and only affected the legs. "These symptoms make it difficult for me, because I like to be active, play sports. But now I need to face reality and do my best , " he said.

Dr. Tanya Simuni, the Northwest Chicago Hospital, USA, said people aged 70 and older are at high risk of getting the disease. Vascular Parkinson's can cause depression, affect behavior and memory . "The diagnosis of this disease is quite difficult because of the lack of accurate tests," the doctor said.

Because the disease does not respond well to the drug, the initial treatment focuses on reducing the risk of stroke such as controlling blood pressure, cholesterol and diabetes. The solution is to quit smoking, exercise, eat healthy and take aspirin daily. Patients can be physiotherapists to improve balance and prevent falls, said Dr. Corneliu Luca, assistant professor of neurology at the University of Miami, USA.

Later, Parkinson's symptoms appeared more and more, the 41st President of the United States remained optimistic and participated in many social activities . his son, former President Bush "child" once shared about his father.

Parkinson's disease (also known as PD) is a degenerative disorder of the central nervous system that affects the movement, balance and control of a patient's muscles.
