Patients Concern
Disease/Condition Glossary
Parkinson's disease: It is a disorder of the central nervous system that affects movement due to damage to nerve cells in the brain, which reduces the levels of dopamine and leads to symptoms such as stiffness, tremors in one hand, shaking, difficulty in walking, coordination, and balance. If proper treatment is not provided at the right time, then symptoms may worsen with time. This condition can last for many years or a lifetime. The symptoms of Parkinson's include tremors in the hands, reduced coordination and balance of the body, changes in posture, tremors in the voice, changes in the sense of smell, and sleep problems. Other common signs and symptoms include constipation, skin problems, sleep disorders, and trouble chewing and swallowing. Usually, most people misunderstand the early signs of Parkinson's disease as normal signs of ageing, and they do not seek medical help. However, treatment at the early stage of this disease is more effective and helpful.
