Most of the movement-related symptoms of Parkinson's disease are caused by a lack of dopamine due to the loss of dopamine-producing cells in the substantia nigra. When the amount of dopamine is too low, communication between the substantia nigra and corpus striatum becomes ineffective, and ...
Loss of motor control is the most familiar symptom of Parkinson's disease. However, people with Parkinson's can also have a range of non-motor issues including sensory, swallowing, gastrointestinal, sleep, and mental health symptoms. Doctors classify stages of Parkinson's based on the severity a...

Parkinson disease, degenerative neurological disorder characterized by the onset of tremor, muscle rigidity, slowness in movement, and stooped posture. Parkinson disease was first described in 1817 by British physician James Parkinson. Learn more about t
The stage can help you get a better feel for where your symptoms fall and what to expect as the disease gets worse. But keep in mind, some people could take up to 20 years to move from mild to more serious symptoms. For others, the change is much faster. ...
Parkinson’s disease is one of Lundbeck’s focus disease areas, and is a chronic progressive neurodegenerative disorder, characterized by the presence of predominantly motor symptoms (resting tremor, rigidity, bradykinesia and postural instability). It is also associated with a diversity of non-motor ...
Parkinson's disease is a common age-related and progressive disease of brain cells (brain disorder) that affect movement, loss of muscle control, and balance. Usually, the first symptoms include a tremor (hand, foot, or leg), also termed a "shaking palsy." Some experts term the disease as...
Parkinson's disease is a progressive nervous system (neurological) disorder that affects your movement and may cause shaking (tremor), muscle stiffness (rigidity), slowing of movement (bradykinesia), impaired balance or other symptoms. Parkinson's disease is a common movement disorder. Parkinsonism ...
